The first electrical hearing aids were carbon and were made possible by the invention of the carbon microphone and were made between 1900 and 1939. Carbon, which can be made to amplify electrical current, was used to provide some amplification prior to the invention of vacuum tubes. Later models often came with mechanical (carbon) amplifiers to try to boost the amount of amplification. The carbon microphone was originally invented for use in the telephone and had the properties of being able to modulate current. It is this property that made it useful in the early electrical hearing aids. An example of a carbon hearing aid. This has an imitation tortoise shell casing.

A barometer is an instrument used for measuring atmosphere pressure thus determining weather changes.The first apparatus generally accepted as a barometer was that set up in Florence in 1644 by Evangelista Torricelli (1608–1647), a mathematician and physicist. Torricelli filled a glass tube with mercury, sealed it at one end, and inverted it with its open end in a dish of mercury. The level always fell a short way down the tube, then settled at a height of about thirty inches. He concluded correctly that the mercury column was sustained by the weight of the air pressing on the open surface of mercury, and further experiments convinced him that the space above the mercury in the tube was a vacuum. He noted that the level rose and fell with changing temperature, but he was unable to use his apparatus to measure variations in the weight of the atmosphere because he had not foreseen that temperature would affect the level of the mercury. News of this experiment circulated quickly among European scientists, who hastened to replicate the experiment. Torricelli's conclusions were not universally accepted because some disputed whether the air had weight, while both Aristotle and the Catholic Church denied the possibility of a vacuum. In France, the philosopher René Descartes (1596–1650) seems to have been the first person, probably in 1647, to attach a graduated scale to the tube so that he could record any changes attributable to the weather. At around this time Duke Ferdinand II of Tuscany organized the first short-lived meteorological network among scientists in other Italian cities, gathering observations of pressure, temperature, humidity, wind direction, and state of the sky.Theis barometer is an example of a household item from the early 20th century, used to determine the day's weather. The barometer is significant as an aid to human social, material and scientific development.Barometer, round, brass housing inset into carved wooden casing (lacquer mostly worn off).

Scarifiers were traditionally used for blood letting, and in folk medicine for the practice of cupping. Spring loaded knives cut the skin, then a warmed metal or glass cup is placed over the cuts. As the air inside the cup cools, it creates a vacuum drawing out the "bad" blood. The process is also related to the ancient medical theory of "humors". This theory dates back to the Hippocratic tradition and persisted through to the mid-19th Century. According to this theory, the body had four "humors", "airs" or "elements" which neeed to be kept in balance. Any imbalance could cause illness and this was often explained in terms of excess fluids. One prescribed treatment was to remove the excess blood which would restore the balance.Square, solid brass object with lever to release blades underneath.Etched on side: Mundy / Londonmetal, blades, bloodletting

This cash ball was used by Cramond and Dickson, a large clothing store on the corner of Liebig and Timor Streets, Warrnambool. The Cash Ball system serviced the ground floor, which measured about 30 metres by 25 metres. An overhead pipe connected each service point in the store, with the pipes connected to the upstairs office. The ball would be filled with a note of details of the sale, and the cash payment; a vacuum system would be activated that would transport the ball upstairs to the office where details were recorded and change assembled. Change was placed in the ball, and the vacuum system activated to return the ball to the correct sales point. A frequent customer has reported that she never remembered the system not working efficiently, and the service was probably quicker than having a cash register at each sales location. John Glass Cramond and James Dickson migrated from Scotland to Melbourne where they opened a Cramond and Dickson store in St Kilda. They were inspired by the growth in Warrnambool after a visit and opened a second store there in 1855. The Cramond and Dickson store, grocers – drapery – ironmongery - chemist, was located on the corner of Liebig and Timor Streets, Warrnambool (now the site of a Mexican restaurant). Both Cramond and Dickson were involved in the business and social aspects of Warrnambool’s community. Cramond and Dickson closed in 1974. An advertisement placed by Cramond and Dickson in The Camperdown Chronicle, Saturday 6th April 1895, states them “showing the latest novelties for the coming winter season” … “import directly from English and Continental manufacturers” … “representatives in London … always in touch with the Newest Continental Fashions” ... “having been established for so many years we know the requirements of the Western District”… “allow 5 percent discount on goods paid for at the time of purchase”.

Mullard Limited was a British manufacturer of electronic components. The Mullard Radio Valve Co. Ltd. of Southfields, London, was founded in 1920 by Captain Stanley R. Mullard, who had previously designed valves for the Admiralty before becoming managing director of the Z Electric Lamp Co. The company soon moved to Hammersmith, London and then in 1923 to Balham, London. The head office in later years was Mullard House in Torrington Place, Bloomsbury, now part of University College London. In 1923, in order to meet the technical demands of the newly formed BBC, Mullard formed a partnership with the Dutch manufacturer Philips. The valves (US vacuum tube) produced in this period were named with the prefix PM, for Philips-Mullard, beginning with the PM3 and PM4 in 1926. Mullard finally sold all its shares to Philips in 1927. In 1928 the company introduced the first pentode valve to the British market. Mullard opened a new manufacturing plant at Mitcham, Surrey in 1929 and in late 1930s Mullard opened a new plant in Blackburn, Lancashire. By 1949 Mullard had produced a number of television sets, such as the MTS-521 and MTS-684 and in 1951 Mullard was producing the LSD series of photographic flash tubes. In the early 1980s, Mullard manufactured the SAA5050, some of the earliest teletext decoding modules made in the UK. In 1957 Philips-Mullard helped to set up the Mullard Radio Astronomy Observatory (MRAO) at the University of Cambridge. Philips continued to use the brand name "Mullard" in the UK until 1988. Mullard Research Laboratories in Redhill, Surrey then became Philips Research Laboratories. As of 2007, the Mullard brand has been revived by Sovtek, producing a variant of the ECC83 and EL34. The Z Electric Lamp Co. continued business into the 1970s operating from premises in Thornton Heath, south London, manufacturing lamps of specialised design but it closed due to the recession in the mid 1970s. Sovtek is a brand of vacuum tube owned by Mike Matthews's New Sensor Corporation and manufactured in Saratov, Russia.

Zeehan & North East Dundas Tramway Bogie 1896 The North East Dundas Tramway (NEDT) was a 2 ft (610 mm) narrow gauge tramway on West Coast Tasmania that ran between Zeehan and Deep Lead (now Williamsford). It was part of Tasmanian Government Railways. The line was opened in 1896 to carry ore from the Williamsford mines to Zeehan where it would be loaded onto another train for shipment to Burnie. The narrow-gauge (2 ft) was chosen because of the extremely difficult terrain that the railway crossed, requiring several big trestle bridges, including one at the foot of Montezuma Falls. After some rain the engine and carriages would get soaked by spray from the falls. There was a break-of-gauge with the mainline 1,067 mm (3 ft 6 in) system at Zeehan. The railway was closed in 1932. The rolling stock for the Tramway was built in the Launceston Railway workshops, and comprised twenty five eight-wheel low-side trucks, tare 3 tons 1 cwt. 1 qr., load 10 tons; six eight-wheel flat trucks, tare 2 tons 18 cwt. 1 qr., load 10 tons; two four-wheel bolster trucks, for carrying long timber, tare 1 ton 19 cwt., load 5 tons; and four passenger cars, each with six cross-seats with reversible backs, to carry eighteen passengers, also a locker for mails and parcels. All trucks and cars have cast-steel wheels 21 inches in diameter and are fitted with automatic vacuum brakes. The trucks have side levers and the cars have hand-screw brakes. The vacuum brake can be worked from the engine or from the passenger cars, which act as brake vans. When this brake was introduced, one effect was to accelerate the journey speed by about 10 minutes owing to more even running on down gradients.

This clear, light green, glass "hand blown" fruit preservation jar was used before the mass manufacturing of "screw topped" fruit preservation glass jars imported from Asia or great Britain. The "Mason's Patent" on the jar was for the screw-neck form of the jar top. The screw neck provided the jar with a vacuum seal (preservation) method of fruit jar storage. The reference on the jar of the actual date that the patent was established was in effect for 13 years with extension of a further 7 years. It was an American world wide patent which resulted in only specific manufacture to Glass Works that had paid the manufacturing levy imposed. The air bubbles in the glass suggests that this jar was "hand blown". This would then place the manufacture date before 1900. Preserves came in glass jars bought at the local grocery store or at a large city store on a shopping expedition. The shape of the jar changed as did the stopper used to seal it. Jars were recycled remaining the property of the manufacturer. History of Mason's.This fruit jar is significant to a rural area such as the Kiewa Valley and in the early 1900's when the preservation of fruit and vegetables was an intrinsic part of the typical rural farm/property family. Local shops could only supply fruit and vegetables as seasons permitted. The travelling "green grocer" was more prevalent in towns and cities but not in semi remote rural areas. Historical: Change of jars - shape, glass, stopper, embossing & use. Aesthetic: Display showing embossing & shape especially if in good condition.This vintage "Mason's Patent", screw on thread lid fruit jar was hand blown (air bubbles).

The Tilley lamp & heaters derives from John Tilley’s invention of the hydro-pneumatic blowpipe in 1813 in England. W. H. Tilley were manufacturing pressure lamps at their works in Stoke Newington in 1818, and Shoreditch, in the 1830s. The company moved to Brent Street in Hendon in 1915 during World War I, and started to work with paraffin (kerosene) as a fuel for the lamps. During World War I Tilley lamps were used by the British armed forces, and became so popular that Tilley became used as a generic name for a kerosene lamp in many parts of the world, in much the same way as Hoover is used for vacuum cleaners. During the 1920s the company had diversified into domestic lamps, and had expanded rapidly after orders from railway companies. After World War II fears about the poisonous effect of paraffin fumes, and widely available electricity, reduced demand for domestic use. The company moved from Hendon to Ireland in the early 1960s, finally settling in Belfast. It moved back to England in 2000.Item is significant as it was an early form of portable heating used in a domestic situation or any small room that required to be heated.

This business was the first Cleaning Service operating in Wodonga, later branching out into cleaning supplies. The business was owned by Charles De Guara who had migrated to Australia from Malta at the age of 16. After various jobs in Melbourne, marriage to Latvian migrant Maija and three children, he and his family moved to Wodonga in 1971. He initially worked at the Wodonga Meat Works and soon became the union delegate, initiating strike action related to inaccurate practices in recording slaughtered animals which affected workers’ payments. This action successfully secured back pay for the workers. Mr De Guara started his cleaning enterprise in 1981 while still at the meatworks and then became full-time with cleaning in 1983. He set up his showrooms in the former Wodonga Library building in Hugh Street, Wodonga. The business employed up to 25 full and part-time workers with a turn over close to a million dollars annually. In addition to cleaning, Mr De Guara sold carpet cleaning machines and vacuum cleaners to individuals as well as businesses, hospitals and clubs. Due to changed family circumstances, the business closed in the late 1980s. Mr. De Guara moved to the Mornington Peninsula district, where he passed away on 30 June 2022This item has a clear connection to a former Wodonga business.A square clock advertising the "Around 'D Clock Cleaning service.

These five photographs were most likely taken in the 1970s in Lithographic Squadron at the Army Survey Regiment, Fortuna, Bendigo. Photos .1P to .3P are annotated with the name of the technicians written on the back. Although Photo .4P is not annotated the technician is positively identified. In these five photos the technician is applying a UV-sensitive pigmented dye emulating one of the print colours to a white opaque polyester sheet mounted on a rotating table in a whirler. The coated sheet was dried before placement in a vacuum light frame beneath a stud registered map negative. They were then exposed to a carbon arc lamp. If there was more than one negative – typical for a type impression or 1st proof, the process was repeated for the other negatives of that print colour. There was a single exposure for composite negatives which was typical for the 2nd and final proof - the pre-press proof. The sheet was removed and washed with water and dried leaving the exposed colour impression. The technician repeated this process using process or spot dyes for remaining publication colours. Type impressions were a combination of the map grid and the topographic features in their correct print colours, forming a base for the cartographer to accurately position map names and symbols on a clear film overlay. The pre-press proof was a cost-effective way of producing a one-off visual copy of the map or chart product. It enabled cartographers to perform a quality inspection and correct any faults before publication. The pre-press proof was deemed authoritative before its release to Print Troop for bulk printing and distribution.This is a set of photographs of lithographic technicians preparing map proofs at the Army Survey Regiment, Bendigo c1960s c1970s.

W.B Withers wrote of Sutton: "In the realm of science Ballarat has become of world-wide fame through the inventions by Mr Henry Sutton, a native of the place. His skill and acquirements in electricity, telegraphy, telephony, photography and also in astronomical and microscopal studies have won for him a high position as a practical scientist, and the credit is the greater as he is a self-taught student … Mr Sutton, before he was fourteen years old, had read every book on science to be found in the library of the Ballarat Mechanics' Institute." The Ballarat School of Mines (SMB) was fortunate to have this genius appointed as the lecturer-in-charge of the new Electricity and Magnetism department from 23 April 1883. Although Henry Sutton submitted his resignation to the Council of SMB in October 1884 it was resolved that he be asked to reconsider, and Mr Sutton continued to teach at SMB until the end of 1886. He was a prominent member of the Camera Club, and many of the other SMB clubs. Sutton had an active and fertile brain, and was known for his inventions, especially his work on the telephone, telephane and carbon lamps. Sutton presented a vacuum pump, worked by water jet, for use in SMB Chemistry classes. His report of 1883 states: ‘A telephonic circuit has been laid down between the [SMB] engine-house and workshops, to be used for experimental purposes.’ Henry Sutton spent much thought on artificial flight, and made some interesting experimental studies with flying birds. The storage of electricty also attracted his attention, and, after much work and thought evolved the Sutton Secondary Battery. A paper on this battery was presented to the Royal Society, London, and was afterwards printed in the 'Transactions'. Henry Sutton is listed on the Federation University Honour Roll at https://www.federation.edu.au/curator/honour-roll/honourroll_sutton.shtmlA crude scientific instrument that measures amps, with a timber base and frame. Terminal posts and sliders contacts are positioned on top of the base, with flex attached. Henry Sutton lectured at the Ballarat School of Mines (SMB) in Electricty and Magnestism between 1883 and 1886. In 1883 Sutton reported: ‘…The class has been unfortunately situated, by having to wait for instruments of precision ordered from England, but which have not come to hand. The delay has caused us to start constructing instruments, which it is hoped will bear favourable comparison with those of older date.'ammeter, henry sutton, electrical, inventor, electricity and magnetism, sutton, scientific instruments

These are the Lenses from the Klimsch Commodore Cartographic Camera that was located in Lithographic Squadron at the Army Survey Regiment, Fortuna, Bendigo. The KLIMSCH Commodore camera was originally introduced to the Survey Regiment in 1953 and was the largest in the Southern Hemisphere. It was replaced with a new model of the same size in 1977. These lenses are from this new model. The new model with its computer-based interface provided productivity gains with improved speed and its consistent results led to less wastage in time and materials. Its variomat lens system provided improved retention of map feature linear weights during the camera reduction process. The camera which was specially made for the Australian Army in Germany was fully automatic and power operated. It was claimed to be one of the biggest automatic cameras of its type in the world. It was made to the specifications of the Royal Australian Army Survey Corps to assist in the production of the very high standard maps for the Australian Army. THIS KLIMSCH COMMODORE CARTOGRAPHIC CAMERA was in operation 1977 - 1997". It was a Precision Darkroom Camera especially suited for Cartographic Reproduction of Line, Continous Tone, Halftone and Colour Separation. Reproduction of Negatives and Positives from a variety of Reflection or Transmission Originals. Its characteristics were: Maximum Negative Size 1.27m sq, Copy Holder (Vacuum) 2m sq, Maximum Enlargement 400%, Maximum Reduction 13%, Automatic 60, 90 and 120cm Focal Length Lens, Transmission or Reflection Originals, Pulsed Xenon, Photo Flood or Fluorescent Tube Light Source, Maximum Reflection Original 1.3m x 1.85m, Maximum Transmission Original 1.3m x 1.85m, Exposure Light Monitoring System." The camera was superseded by computerized image manipulation software associated with the Automap system. These significant and extremely high-quality Lenses were retrieved by WYCOMBE Constructions Pty Ltd during the demolishment of the camera in 1997 and then mounted on a display board. See also Item 6189.4P for more photographs of the camera.Lenses from the Klimsch Commodore Cartographic Camera mounted on a very heavy timber display board.

In March 1995 ATCV had circulated a proposal for an ‘Australia Corps’. The proposal emerged over time from ATCV board and staff through debate and experience. ATCV Board member Alan Wright had written earlier: “There is in our society a terrible vacuum for adolescents to give expression to their independence and idealism in a constructive way, a chance to try themselves out independent of their parents/teachers in adult roles.” ATCV’s Brisbane office manager Phil Harrison had first been involved with ATCV as a volunteer from UK, drew together ideas about an ‘Australia Corps’, that had been discussed with Alan Wright, John Fenton and others at the ATCV staff/board planning workshop at Sorrento in December 1993 and “…based upon our experience and participation in the LEAP program and observations of Conservation Corps around the world”. The concept of a six-month program for young people with a training wage and accredited training which encouraged both competencies and personal development emerged, with a standard format of ten participants working fopr six months under the direction of a supervisor. The ‘Australia Corps’ proposal was widely distributed to Federal, State and Territory parliamentarians and received positive feedback. The Liberal Party, then in Opposition, included the idea of a “Green Army” in their environmental policy, placing more emphasis on environmental outcomes and less on job creation than the Keating ALP Government had. A young and up-and-coming parliamentarian, Tony Abbott MP, was enthusiastic and was to visit several ATCV projects (both before and after Green Corps started) to learn about their workings direct from volunteers and CVA staff. Several times he visited projects with Ian Smith project and Ian recalls being impressed by the efforts he made to talk at length with all participants. Tony Abbott took a personal interest in the progress of Green Corps. Colin Jackson and Phil Harrison were guests of Abbott in Parliament House, Canberra, on the evening of 20 August 1996. The Federal Treasurer, Peter Costello, announced in his first Budget Speech that: - “the Government will provide $42 million over the next 3 years to establish the Green Corps. The Green Corps will be open to young Australians aged 17 to 20 to demonstrate their commitment to the environment by working on projects to preserve and restore Australia's natural environment and cultural heritage. The projects will also contribute to their career and employment prospects through training, skills development, work experience and personal development.” ATCV’s chief executive officer Colin Jackson worked with senior staff Madeline Townsend, Garry Snowden, Phil Harrison, and John Fenton to fine-tune the ATCV proposal. On the strength of unique national coverage and credible record ATCV went on to win the tender to administer and manage the day-to-day operations of the Green Corps program for five years (1997-2002). Winning a $36 million contract was a big breakthrough for ATCV. Fourteen years before, a small non-profit group had started in Ballarat in country Australia with a vision – but little else. Its key people had shaped opinion and won political support for a concept. There was about to be transformation from hand-to-mouth existence into a nation-wide business with resources to build for the long term. This documents records many positive comments about Green Corps and ATCV's implementation of it.24pp illustrated booklet printed in green and some gold.atcv green corps australia-corps tony abbott mp phil-harrison

The discovery of the first telescope in 1608 can be attributed to Hans Lippershey of the Netherlands when he discovers that holding two lenses up some distance apart bring objects closer. He applies for a patent on his invention and this becomes the first documented creation of a telescope. Then in 1668, Newton produces the first successful reflecting telescope using a two-inch diameter concave spherical mirror. This opened the door to magnifying objects millions of times far beyond what could ever be obtained with a lens. It wasn’t until 1729 that Chester Moor Hall develops an achromatic lens (two pieces of glass with different indices of light refraction combined produce a lens that can focus colours to almost an exact point resulting in much sharper images but still with some distortion around the edges of the image. Then in 1729 Scottish instrument maker James Short invents the first parabolic and elliptic, distortion-less mirror ideal for reflecting telescopes. We now come to John Dollond who improves upon the achromatic objective lens by placing a concave flint glass lens between two convex crown glass lenses. This had the effect of improving the image considerably. Makers Information: John Dollond (1707-1761) London England he was a maker of optical and astronomical instruments who developed an achromatic (non-colour distorting) refracting telescope and practical heliometer. A telescope that used a divided lens to measure the Sun’s diameter and the angles between celestial bodies. The son of a Huguenot refugees Dollond learned the family trade of silk weaving. He became proficient in optics and astronomy and in 1752 his eldest son, Peter joined his father in an optical business, in 1753 he introduced the heliometer. In the same year, he also took out a patent on his new lenses. He was elected a fellow of the Royal Society in May 1761 but died suddenly in November and his share in the patent passed to his son Peter. In subsequent squabbles between Peter and the many London opticians who challenged his patent, Peter’s consistent position was that, whatever precedents there may have been to his achromatic lenses, his father had independently reached his practical technique on the basis of his theoretical command of Newtonian optics. As a result of maintaining his fathers patent, Dollond s became the leading manufacturer of optical instruments. For a time in the eighteenth and nineteenth century the word 'Dollond' was almost a generic term for telescope rather like 'Hoover; is to vacuum cleaner. Genuine Dollond telescopes were considered to be amongst the best. Peter Dollond (1731-1820) was the business brain behind the company which he founded in Vine Street, Spitalfields in 1750 and in 1752 moved the business to the Strand London. The Dollonds seem to have made both types of telescopes (reflecting and refracting), possessing the technology to produce significant numbers of lenses free of chromatic aberration for refracting telescopes. A Dollond telescope sailed with Captain Cook in 1769 on his voyage to observe the Transit of Venus. Thomas Jefferson and Admiral Lord Nelson were also customers of the Dollonds. Dollond & Co merged with Aitchison & Co in 1927 to form Dollond & Aitchison, the well-known high street chain of opticians, now fully part of Boots Opticians. They no longer manufacture but are exclusively a retail operation.    John Dollond's experiments in optics and how different combinations of lenses refract light and colour gave a better understanding of the divergent properties of lenses. That went on to inform and pave the way for the improvement of our understanding of optics that are represented today. Dollond was referred to in his time as the "Father of practical optics" as a leader in his field he received many prestigious awards. The telescope in the collection is a good example of one of Dollonds early library telescopes and its connection with one of England's 18th-century pioneers in optical development is in itself a significant and an important item to have within the collection.
