In the 18th century, spring scales appeared. To produce these scales, a manufacturer would use the resistance of a spring to calculate weights, which could be read automatically on the scale’s face. The ease of use of spring scales over balance scales is what led most post offices to outfit their clerks with spring postal scales. One of the most common types of spring scales was the kitchen scale—also known as a family or dial scale. Designed for horizontal surfaces, these scales used the weight of goods in a pan at the top of the scale to force the spring down. Such scales were common in early-20th-century households and were sold by Sears and Montgomery Ward. Many had flat weighing surfaces but some were topped by shallow pans. Companies such as Salters, Chatillon, and Fairbanks made both. SALTER HOUSEWARES began in the late 1760 in the village of Bilston, England. At this time Richard Salter, a spring maker, began making 'pocket steelyards', a scale similar to the fisherman's scale of today. By 1825 his nephew George had taken over the company, which became known as George Salter & Co. and later established a large, well equipped manufacturing site in the town of West Bromwich. The business thrived throughout the 1900s, and in 1972 the company was purchased by Staveley Industries Plc. In 2002, the management team at Salter Housewares Ltd, backed by Barclays Private Equity, bought the company out from the group, to concentrate on its consumer businesses.

Resinol is used to treat several different types of skin ailments. Resinol was developed by Dr. Merville Hamilton Carter (1857-1939) in his private practice as treatment for his patients in Baltimore, Maryland during the late 19th century. In 1895, Carter, along with his brother Allan L. Carter and his cousin Henry Stier Dulaney founded the Resinol Chemical Company and began to mass-produce the ointment and other medical products. After over forty years of selling Resinol, the company had John H. Buffham & Co. as an outlet in Great Britain and was a successful global distributor. Henry LeRoy Carter Sr., the son of Dr. Carter, began running the company after the deaths of his father and other staff members. The company's sales began to decline in the 1940s, and after the death of Henry LeRoy Carter Sr. in 1951, his son Henry LeRoy Carter Jr. took the place of his father and grandfather as president of the Resinol Chemical Company. At that time, the company focused more on soap manufacturing, but continued to sell Resinol. For the rest of the 20th century, Resinol's popularity continued to dwindle.

This tester was used between 1950 and 1980's. As part of the Occupation, Health and Safety requirements, equipment used to monitor the performance of electricity producing generators, regularly, hand held testers were used to check the insulation and the "earth" pin were up the the required operational levels. As the generators and their ancillary monitoring equipment was spread over a large area and cumbersome to service small hand held devices were required. These had to always be safe for the user to operate. A selected range of high quality meters were recalibrated every two years in the Meter and Calibration Laboratory at Yarraville(near Melbourne) This meter is very significant to The Kiewa Hydro Electricity Scheme because it was an integral part of maintaining the electricity producing water driven generators of the power stations. The reason why this meter was so essential is that provided the safety check on equipment used to monitor each Hydro Generator that they were complying within the grid network parameters. Grid parameters are set so that if there is an electrical fault on the system, that fault can be attended to with a very small change in the output stability of each generator. It is essential that the voltage of the network remain within the set limits. Generators are at Dartmouth, Mackay, Clover, West Kiewa, Yarrawonga, Cain Curran and three Power Stations in the Thornton area.This hand driven current generator produces 500 volts by winding the handle(on funnel curved side) to keep the voltage constant(one minute per test). The whole body is made from caste aluminium. One of the functions of this meter is to test the isolation resistance of any equipment being tested. This is to see if that equipment is safe to handle(no electrical shocks). The second function is to test the earth pin of any portable electrical equipment. The turn key on one side can direct which function is required(marked insulation or continuity). On the top side(enclosed in a glass fronted marked scale) is a continuity scale(top) and an insulation scale(bottom). This is covered , when not in use by "flip up" lid with manufacturer's details and name of the instrument. Opposite the winder are two screw tight knobs.

The pocket balance was first created in 1770 by Richard Salter in the UK. From the late 18th century onwards these small scales were widely used in markets, grocers and farm shops – wherever people needed to be able to verify the weight of goods to be purchased in order to calculate the correct pricing. Because it was portable, and simple to use, the pocket balance was ideal for weighing goods where accuracy was not required. This balance appears to have been used for weighing fish.Pocket spring scales made of steel. There is a spring fixed at one end with a hook to which an object can be attached at the other. At the top of the scales there. is a metallic ring to fasten the object. This is attached to the main body which on one side has measurements inscribed into the metal surface. Inside the body is a spring loaded mechanism which moves along the scales when weight is added to a hook at the bottom of the shaft.At the top - POCKET BALANCE ARROW and the letters M P inside an oval.scales pocket-balance spring-balance measuring-instrument

An octant is an astronomical instrument used in measuring the angles of heavenly bodies such as the sun, moon and stars at sea in relation to the horizon. This measurement could then be used to calculate the altitude of the body measured, and then the latitude at sea could also be calculated. The angle of the arms of an octant is 45 degrees, or 1/8 of a circle, which gives the instrument its name. Two men independently developed the octant around 1730: John Hadley (1682–1744), an English mathematician, and Thomas Godfrey (1704–1749), a glazier in Philadelphia. While both have a legitimate and equal claim to the invention, Hadley generally gets the greater share of the credit. This reflects the central role that London and the Royal Society played in the history of scientific instruments in the eighteenth and nineteenth century's. There were also two others who are attributed to having created octanes during this period, Caleb Smith, an English insurance broker with a strong interest in astronomy (in 1734), and Jean-Paul Fouchy, a mathematics professor and astronomer in France (in 1732) In 1767 the first edition of the Nautical Almanac tabulated lunar distances, enabling navigators to find the current time from the angle between the sun and the moon. This angle is sometimes larger than 90°, and thus not possible to measure with an octant. For that reason, Admiral John Campbell, who conducted shipboard experiments with the lunar distance method, suggested a larger instrument and the sextant was developed. From that time onward, the sextant was the instrument that experienced significant development and improvements and was the instrument of choice for naval navigators. The octant continued to be produced well into the 19th century, though it was generally a less accurate and less expensive instrument. The lower price of the octant, including versions without a telescope, made it a practical instrument for ships in the merchant and fishing fleets. One common practice among navigators up to the late nineteenth century was to use both a sextant and an octant. The sextant was used with great care and only for lunar sightings while the octant was used for routine meridional altitude measurements of the sun every day. This protected the very accurate and pricier sextant while using the more affordable octant for general use where it performs well. The invention of the octant was a significant step in providing accuracy of a sailors latitude position at sea and his vessels distance from land when taking sightings of land-based landmarks.Octant with metal handle, three different colored shades are attached, in wooden wedge-shaped box lined with green felt.

A Large Rare mid 19th Century Balance Scale (also called a Beam Scale) Made in England by W&T Avery a British manufacturer of weighing machines. The company was founded in the early 18th century and took the name W & T Avery in 1818. The undocumented origin of the company goes back to 1730 when James Ford established the business in the town of Digbeth. On Joseph Balden the then company’s owner’s death in 1813 William and Thomas Avery took over his scale making business and in 1818 renamed it W & T Avery. The business rapidly expanded and in 1885 they owned three factories: the Atlas Works in West Bromwich, the Mill Lane Works in Birmingham and the Moat Lane Works in Digbeth. In 1891 the business became a limited company with a board of directors and in 1894 the shares were quoted on the London Stock Exchange. In 1895 the company bought the legendary Soho Foundry in Smethwick, a former steam engine factory owned by James Watt & Co. In 1897 the move was complete and the steam engine business was gradually converted to pure manufacture of weighing machines. The turn of the century was marked by managing director William Hipkins who was determined to broadening the renown of the Avery brand and transforming the business into a specialist manufacture of weighing machines. By 1914 the company occupied an area of 32,000m² and had some 3000 employees. In the inter-war period the growth continued with the addition of specialized shops for cast parts, enamel paints and weighbridge assembly and the product range diversified into counting machines, testing machines, automatic packing machines and petrol pumps. During the second world war the company also produced various types of heavy guns. At that time the site underwent severe damage from parachute mines and incendiary bombs.Then from 1931 to 1973 the company occupied the 18th-century Middlesex Sessions House in Clerkenwell as its headquarters. Changes in weighing machine technology after World War II led to the closure of the foundry, the introduction of electronic weighing with the simultaneous gradual disappearance of purely mechanical devices. The continued expansion was partly achieved through a series of acquisitions of other companies. After almost a century of national and international expansion the company was taken over by GEC in 1979. Keith Hodgkinson, managing director at the time, completed the turn-around from mechanical to electronic weighing with a complete overhaul of the product range of retail scales and industrial platform scales. In 1993 GEC took over the Dutch-based company Berkel and the Avery-Berkel name was introduced. In 2000 the business was in turn acquired by the US-American company Weigh-Tronix, who already owned Salter, and is today operating as Avery Weigh-Tronix.

Langlands Company History: Langlands foundry was Melbourne's first foundry and iron shipbuilder established in 1842, only 8 years after the founding of the Victorian colony by two Scottish immigrants, Robert Langlands and Thomas Fulton, who had formed a partnership before emigrating (1813–1859). The business was known as the 'Langlands Foundry Co'. Henry Langlands (1794-1863), left Scotland in 1846 with his wife Christian, née Thoms, and five surviving children to join his brother Robert. By the time he arrived in early January of 1847 the partnership of Robert Langlands and Fulton had dissolved as Fulton had gone off to establish his own works. It was at this time that the two brothers took over ownership of Langlands foundry. Several years later Robert retired and Henry became sole the proprietor. The foundry was originally located on Flinders Lane between King and Spencer streets. Their sole machine tool, when they commenced as a business, was a small slide rest lathe turned by foot. In about 1865 they moved to the south side of the Yarra River, to the Yarra bank near the Spencer Street Bridge and then in about 1886 they moved to Grant Street, South Melbourne. The works employed as many as 350 workers manufacturing a wide range of marine, mining, civil engineering, railway and general manufacturing components including engines and boilers. The foundry prospered despite high wages and the lack of raw materials. It became known for high-quality products that competed successfully with any imported articles. By the time Henry retired, the foundry was one of the largest employers in Victoria and was responsible for casting the first bell and lamp-posts in the colony. The business was carried on by his sons after Henry's death. The company was responsible for fabricating the boiler for the first railway locomotive to operate in Australia, built-in 1854 by Robertson, Martin & Smith for the Melbourne and Hobson's Bay Railway Company. Also in the 1860s, they commenced manufacture of cast iron pipes for the Board of Works, which was then laying the first reticulated water supply system in Melbourne. Langlands was well known for its gold mining equipment, being the first company in Victoria to take up the manufacture of mining machinery, and it played an important role in equipping Victoria's and Australia's first mineral boom in the 1850s and 1860s. Langlands Foundry was an incubator for several engineers including Herbert Austin (1866–1941) who worked as a fitter at Langlands and went on to work on the Wolesely Shearing machine. He also founded the Austin Motor Company in 1905. Around the 1890s Langlands Foundry Co. declined and was bought up by the Austral Otis Co. in about 1893. History for Grimoldi: John Baptist Grimoldi was born in London UK. His Father was Domeneck Grimoldi, who was born in Amsterdam with an Italian Father and Dutch mother. Domeneck was also a scientific instrument maker. John B Grimoldi had served his apprenticeship to his older brother Henry Grimoldi in Brooke Street, Holburn, London and had emigrated from England to Australia to start his own meteorological and scientific instrument makers business at 81 Queens St Melbourne. He operated his business in 1862 until 1883 when it was brought by William Samuel and Charles Frederick, also well known scientific instrument makers who had emigrated to Melbourne in 1875. John Grimoldi became successful and made a number of high quality measuring instruments for the Meteorological Observatory in Melbourne. The barometer was installed at Warrnambool's old jetty and then the Breakwater as part of the Victorian Government's insistence that barometers be placed at all major Victorian ports. This coastal barometer is representative of barometers that were installed through this government scheme that began in 1866. The collecting of meteorological data was an important aspect of the Melbourne Observatory's work from its inception. Just as astronomy had an important practical role to play in navigation, timekeeping and surveying, so the meteorological service provided up to date weather information and forecasts that were essential for shipping and agriculture. As a result, instruments made by the early instrument makers of Australia was of significant importance to the development and safe trading of companies operating during the Victorian colonies early days. The provenance of this artefact is well documented and demonstrates, in particular, the importance of the barometer to the local fishermen and mariners of Warrnambool. This barometer is historically significant for its association with Langlands’ Foundry which pioneered technology in the developing colony by establishing the first ironworks in Melbourne founded in 1842. Also, it is significant for its connection to John B Grimoldi who made the barometer and thermometer housed in the cast iron case. Grimoldi, a successful meteorological and scientific instrument maker, arrived in the colony from England and established his business in 1862 becoming an instrument maker to the Melbourne Observatory. Additional significance is its completeness and for its rarity, as it is believed to be one of only two extant barometers of this type and in 1986 it was moved to Flagstaff Hill Maritime Village as part of its museum collection. Coast Barometer No. 8 is a tall, red painted cast iron pillar containing a vertical combined barometer and thermometer. Half way down in the cast iron framed glass door is a keyhole. Inside is a wooden case containing a mercury barometer at the top with a thermometer attached underneath, each with a separate glass window and a silver coloured metal backing plate. Just below the barometer, on the right-hand side, is a brass disc with a hole for a gauge key in the centre. The barometer has a silvered tin backing plate with a scale, in inches, of "27 to 31" on the right side and includes a Vernier with finer markings, which is set by turning the gauge key. The thermometer has a silvered tin backing plate with a scale on the left side of "30 to 140". Each of the scales has markings showing the units between the numbers.Inscription at the top front of the pillar reads "COAST BAROMETER" Inscribed on the bottom of the pillar is "No 8". and "LANGLANDS BROS & CO ENGINEERS MELBOURNE " The barometer backing plate is inscribed "COAST BAROMETER NO. 8, VICTORIA" and printed on the left of the scale, has "J GRIMOLDI" on the top and left of the scale, inscribed "Maker, MELBOURNE". There is an inscription on the bottom right-hand side of the thermometer scale, just above the 30 mark "FREEZING" Etched into the timber inside the case are the Roman numerals "VIII" (the number 8)flagstaff hill, warrnambool, maritime village, maritime museum, flagstaff hill maritime museum & village, shipwreck coast, great ocean road, warrnambool breakwater, coast barometer, coastal barometer, barometer, weather warning, ports and harbours, fishery barometer, sea coast barometer, austral otis co, coast barometer no. 8, henry grimoldi, henry langlands, john baptist grimoldi, langlands foundry co, meteorological instrument maker, robert langlands, scientific instrument maker, thermometer, thomas fulton

The disc-shaped design of these 1LB and 2 LB metal weights enables them to be stacked one on top of the other. The weights are used with a balance scale to accurately weigh the mass of items such as grain, sugar, meat or potatoes. They could have been used in retail or wholesale businesses like a general store or a grain merchant’s premises. The user would place either one or both of these weights on one side of a balance scale. Goods would then be placed onto the other side of the scale until the beam between both sides of the scale was level, showing that the weight of the goods was as heavy as the weight or weights on the other side. These two weights are marked in Imperial units. An Imperial Standard 1LB is equal to 453.592grams. The British Weights and Measures Act of 1824 defined official standards for weights and measurements. This ensured that uniform measurements would be used for trade throughout the Empire. Towns and districts would have an official set of Imperial Standard Weights and Measures. Inspectors periodically used this official set to check the accuracy of traders’ own weights and measures. There would be penalties such as fines or imprisonment for people who broke these laws. The State of Victoria had its own Weight and Measures Act in 1862 and a decade later the inspectors in local councils used their local set of weights and measures to test the local businesses measuring equipment. In the nineteenth century the Victorian Customs Department carried out this role but this was handed over to the Melbourne Observatory at the beginning of the twentieth century. The Measures Branch then followed on with this task from the 1940s until 1995. Australia began converting to the metric system in the 1960s, beginning with its money. The conversion from imperial to metric units of measurement in Australia took place from 1970 and was completed in 1988 when metric units became the only legal unit of measurement.

In the nineteenth century the Victorian Customs Department carried out this role but this was handed over to the Melbourne Observatory at the beginning of the twentieth century. The Measures Branch then followed on with this task from the 1940s until 1995. Australia began converting to the metric system in the 1960s, beginning with its money. The conversion from imperial to metric units of measurement in Australia took place from 1970 and was completed in 1988 when metric units became the only legal unit of measurement.Weight; 2 lbs.

A Storm Glass and Thermometer such as this one would be used in predicting or forecasting the weather. Farmers used predictions they read from their Storm Glass to prepare for stormy weather or for choosing a good time for planting or harvesting their crops. This could mean to them the difference between a good year and a year without income. This design has been in use since the early 1800’s. According to Admiral Fitzroy (who studied the storm glass and wrote instructions on its use) the liquid in the glass changes composition and appearance according to the direction of the air moving around it. He advised the user to disturb the contents once or twice a year by tipping it upside down and shaking it gently. Item is a good example of a barometer/thermometer that would have been in most homes and farms from the late 19th century and early 20th century. This item would have been massed produced at the time therefore easily available and quite cheap to purchase making this particular item not very significant as not associated with a historic person or property or with a known manufacturer or date.Storm Glass and Thermometer, commonly called a 'Cottage Barometer', mounted on a rectangular dark rectangle of wood, top corners rounded. The Storm Glass (or weather glass, or chemical weather glass) is suspended in a long oval shaped hole in the wood on left side, held in place at top and at bottom with 2 metal bands secured by nails. The glass of this gauge is hand blown, sealed at the top with another layer of glass. The watery fluid in the storm glass is opaque brownish colour with dark particles floating in it. (Storm glasses were usually filled with a variation of a mix of camphor, distilled water, ethyl alcohol and silver nitrate.) The alcohol thermometer is mounted on the right side of the wood, bulb resting in a hollow, attached at top and near base by 2 thin metal strips, with clover-leaf shaped ends, nailed into place. Over the bulb is nailed a metal guard with 3 ventilation slits cut into it. On left of thermometer is a scale, stamped into wood, 30 below zero to 130 above zero, in 2 degree intervals. A border of 2 thin parallel lines, with remnants of light coloured paint, is around the block of wood. On the reverse side, a metal plate is nailed to the top with a mounting hole in it. Impressed sideways along edge of barometer is "STORMY" "CHANGE" "FAIR". Across the top of the thermometer is a fleur de leis in the wood, and above this it is stamped "FAHRENHEIT". On right of the thermometer, stamped into the wood, is "BLOOD/HEAT", "SUMR/HEAT", "TEMPE/RATE", "FREEZ/ING". On the back of the wood, at the base, are remnants of a white sticker with "...111.73". Carved into the wood is "HOLLAND / AV". flagstaff hill, warrnambool, shipwrecked coast, flagstaff hill maritime museum, maritime museum, shipwreck coast, flagstaff hill maritime village, great ocean road, barometer, cottage barometer, storm glass, thermometer, chemical weather glass

The steam engine indicator, or dynamometer, is an instrument used on a steam engine (such as that of a vessel or train) to measure and record the change in the pressures of the engine’s cylinders during their operating cycle. The engineer would use it to identify problems or defects such as bad valve settings or constricted steam pipes. It could indicate the difference in efficiency caused by adjustments made to the engine, being able to instantly measure the variation of pressure from the engine stroke at any given time. This force of power would be registered by a pencil, fitted to the adjustable arm, which would trace a line on paper wound around the cylinder. The recorded information could be used in conjunction with mathematical tables. This particular instrument was made by T.S. Mc Innes, one of the better manufacturers of engine indicators. Mc Innes engine indicators were still being used in the mid 1900’s. This specific instrument was used by Mark Forsythe of North Berwial, Scotland and late of Ararat, Victoria when he was chief engineer on the “SS Talawena” in 1892. The Port of Warrnambool, in Victoria, harboured steam ships that carried both passengers and cargo along the south west coast in the late 1800’s and into the 1900’s. The engineer of a steam ship was responsible for reaching and maintaining the optimum level of steam energy to serve the locomotion and efficiency of the steam ship. The engineer would use a steam engine indicator to measure and record information to achieve this purpose. Engine Dynamometer or Steam Engine Indicator in square, fitted oak case. This brass instrument is used to measure and record steam pressure for setting up and adjusting valves on a steam engine. It has an oscillating recording drum with vertical, silver clip attached for holding paper in place around the drum. The drum oscillates left to right. There is a pulley attached to a length of cord, which is attached to the drum. Beside the drum is a fine metal arm, vertically adjustable, small hole in the end to hold a pencil. Inscription stamped into bracket of the arm. The engine indicator is mounted on a hinged side of the case that swings out ready for use. Attached chains prevent the side from opening past vertical. There is storage for other accessories and an empty compartment in the base (where a scale or ruler may have been located). The case has a collapsible wooden handle, brass hinges and two brass, hook-shaped catches. There is a code stamped inside the lid. It contains a brass, ‘T’ shaped steam-cock (or stop cock) with two open ends made of metal pipe with different sized threads. (Turning the handle on top opens and closes the space in the pipe and would close off the flow of steam from one end to the other.) Also inside the case are three different spiral springs, each with a threaded nut on the end that has a threaded hole inside it.

The Crane foundry opened some time before 1827 and was known as Atherton’s Foundry, run by James Atherton and Henry Crane. Initially it was a brass foundry, but by 1827 iron castings were also produced on the site. The main products were castings for the building industry, ironmongery and brassware. In the 1830s castings for the hand tool and lock industries were added to the product range and by 1836 Henry Crane had taken control of the business. The company became known as the Crane Foundry in 1847 with its own registered trademark. By the 1850s iron weights were produced, and a design was registered in 1872 with roundels decorating the edge. Brass weights were also produced, mainly after the regulation of 1890 that required weights of 2oz. or less to be made of brass. In the early 1900s the foundry began to produce castings for electric motors and continued to do so throughout its life. The Crane family continued to control the company until 1917 when William Cyril Parkes of lock makers Josiah Parkes & Sons Limited, Willenhall became a majority shareholder. Things were going well until the company’s liabilities spiraled out of control with the rise in electricity and gas prices along with the loss of two of the company’s largest customers. The factory went into liquidation and then closed in 2006 an end to one of Wolverhampton’s oldest companies.An item made by one of England's foundry’s based in Wolverhampton that exported items all over the world for many years.

T & C Clark & Company Limited, based at Shakespeare Foundry, was founded in 1795 by Thomas and Charles Clark and grew to be one of the largest iron foundries in Wolverhampton. The firm was the pioneers of Enamelled Cast ironware and the founder Charles Clerk went on to became mayor of Wolverhampton in 1860 after also serving as a Councilor, Alderman, and later Chief Magistrate. The company exhibited many products at the International Exhibition of 1862 at South Kensington, alongside the gardens of the Royal Horticultural Society. The company was also awarded the silver medal for its products at the International Paris Exhibition in 1878. The company's product range included thousands of items, both domestic and industrial. T & C Clark pioneered the use of enamelled cast ironware, after taking out a patent in 1839 guaranteed to be free of lead or arsenic. In the late 1940s and 1950s the company produced acid-resisting enamelled cast iron boiling pans; steam-jacketed pans; stills; square and rectangular tanks; open and closed mixing vessels; flanged pipes; bends and tees; laboratory equipment; small scale plant; evaporating bowls; beakers; sulphonates; and glass-lined mild steel tanks for beer, mineral water, and food. The company is listed as enamelled chemical plant manufacturers in Kelly's 1962 Wolverhampton Directory, but within a few years, the company had ceased trading.The item is significant as it was used as a domestic kitchen or camp fire item used to cook food safely without the concern that the metal may contain lead or arsenic as earlier cooking utensils had.

Glass manufacturing has evolved over thousands of years. Glass making has been traced back to 3500 BC in Mesopotamia. The earliest known glass objects were beads, perhaps made by accident while working with metal. In the late Bronze Age, several civilizations discovered how to make vessels and glass bottles by wrapping threads of melted glass around cores of sand or clay. Later, moulds were used to form dishes and table wares. Around the 1st century BC, glassblowing was discovered. This made glass containers less expensive than pottery. Mould-blown glass, the process of blowing a piece of molten glass into a wooden or metal mould, was invented during the 1st century AD. This technique was faster with more consistent results. It paved the way for mass production. It wasn’t until the late 1800s that the production process to become more efficient. In 1887, a company in England created a semi-automatic process that could produce up to 200 bottles an hour. This process has been refined to the point where modern machines can yield more than 600 containers per minute. Blown vs. Manufactured Glass Bottles Nowadays, glass bottles, jars, and cups are usually manufactured on a bigger scale than is found in individual glassblowing studios. If we still depended on hand-blown glass for all of our glass containers, we would see some major differences in the process of creating bottles and jars. First, there's the time. Hand blowing glass takes a significant amount of time, even for one simple container. In contrast, hundreds of jars per minute can be made using modern technology. This leads to the second advantage: price. Because of the automated and streamlined process, the price for manufactured containers is much lower than that of hand-blown glass. Third, manufactured bottles will be much more consistently uniform than bottles blown by hand. Automated glass manufacturing produces nearly identical batches of jars. Glass blowing is awesome for unique, beautiful pieces of art. But for lots of lower priced and uniformly shaped containers, automatic manufacturing is the preferred method to create glass bottles and jars. https://www.containerandpackaging.com/resources/glass-bottles-brief-history The invention and development of glass for domestic items including bottles, has been nothing short of revolutionary. The use of glass bottles, that could be easily washed, led to improved hygiene, and mass manufacturing of drinks of all types, including milk, cordial and alcoholic beverages.Green Glass Bottle Possibly a ginger beer bottle.Concave indentation at the base.

This handheld portable pendulum quadrant scale was used to weigh small paper items such as letters and documents, powdered chemicals or metals like gold, and animal fleece samples. This mechanical scale can weigh up to a maximum of 10 ounces, which is about 285 grams or one-and-a-half cups of brown sugar. The operator holds the scale’s ring and connects the item to be weighed onto the wire clip. The weight of the item causes the pendulum to pivot, and the scale measures the weight of the object, indicated by the arrow. This scale belonged to Dr William Roy Angus and is now part of Flagstaff Hill’s comprehensive W.R. Angus Collection, donated by the family of Dr W R Angus, 1901-1970, surgeon and oculist. The W.R. Angus Collection: - The W.R. Angus Collection includes historical medical equipment, surgical instruments and material belonging to Dr Edward Ryan and Dr Thomas Francis Ryan, (both of Nhill, Victoria) and Dr Angus’ own belongings. The Collection’s history spans the medical practices of the two Doctors Ryan, from 1885-1926 plus that of Dr Angus, up until 1969. It includes historical medical and surgical equipment and instruments from the doctors Edward and Thomas Ryan of Nhill, Victoria. Dr Angus married Gladys in 1927 at Ballarat, the nearest big city to Nhill where he began as a Medical Assistant. He was also Acting House surgeon at the Nhill hospital where their two daughters were born. During World War II He served as a Military Doctor in the Australian Defence Force. Dr Angus and his family moved to Warrnambool in 1939, where Dr Angus operated his own medical practice. He later added the part-time Port Medical Officer responsibility and was the last person appointed to that position. Both Dr Angus and his wife were very involved in the local community, including the planning stages of the new Flagstaff Hill and the layout of the gardens there. Dr Angus passed away in March 1970.This letter scale is the only one of its type in our collection. It is an example of objects belonging to Dr. W. R. Angus, 1901-1970, surgeon and oculist. The W.R.

The core memory of this calculator was a #D metal box. The pin must have been attached to a card reader or keyboard to enter the programme. According to Sharp’s serial numbering scheme, which encodes the month and year of manufacture of their electronic calculators at least through the mid-1970’s, this calculator was manufactured in September 1969. The technology used in the Memorizer 30/Memorizer 60 was very typical of that of the late 1960s, with small-scale integrated circuits containing a few gates or flip-flops, and a magnetic core memory array for storing the program steps that the user keyed in using the calculator attached to the device. (with thanks to Rick Bensene, Curator of the Old Calculator Museum, Beavercreek, Oregon, USA) ISharp Memorizer 60 (Model CSA-12). The Model CSA-12, called the "Memorizer 60", was an accessory that could be connected to a Sharp Compet 22 or Compet 32 electronic calculator to allow these machines to be "learn mode" programmed. Programs were "learned" from the keyboard of the calculator, and stored within a core memory array in the Memorizer 60. Programs of up to 60 steps could be stored. The Memorizer 60 could them "play back" the stored steps at high speed, to allow relatively complex math operations to be performed.

This model of a mechanical ore roasting and chloridising furnace was invented and patented by Thomas Edwards of the Edwards Pyrites Smelting and Ore Reduction Company. This new type of furnace produced a high standard of sulphur free ore known as ‘sweet roasted’. Edwards used this model for demonstrations in the USA. Of note is the central large vertical cogwheel (externally driven) which drives small vertical cogwheels via angled cogging drives. These in turn drive a horizontal wheel. Each side of the vertical wheel is set on an opposite side to the horizontal wheel of its neighbours, resulting in opposite direction rotation of neighbouring horizontal wheels. Each horizontal wheel turns a rabble (set of vertical iron paddles) within the furnace. These rabbles, each turning in opposite direction to its neighbours, move the roasting ore in a zig-zag path through the furnace. The elongated furnace with its line of rabbles produced a much ‘sweeter’ roasted ore than could be obtained from a typical tank-shaped furnace. In 1924, when the model was donated to the Ballarat School of Mines, Ballarat’s Courier newspaper reported, ‘Apart from its historical and education value, the gift should serve to stimulate the inventive faculties of the students who have to win fame for the school and for themselves in the metallurgical world.’ The furnace model was donated to Ballarat School of Mines and used as an educational prop from 1924. The model relates to the mining industry which is a significant part of Ballarat's history and heritage. Ballarat School of Mines is the oldest Technical School in Australia and is celebrating 150 years in 2020.Metal model of Edwards' Ore Reduction Furnace.

In 1903 the oxyacetylene welding process was developed. Around the same time, new cryogenic air separation processes, based on work undertaken by Carl von Linde and others, replaced the barium oxide process. This paved the way for larger scale and more efficient production. British Oxygen Company, [1905 to 1969] was formally BRIN'S Oxygen Company Ltd from 1886 to 1905. In 1969 it became BOC.
