Hexamine stoves, such as this example, were used in the field by soldiers for the preparation of food and boiling of water. The stove would have been fuelled by hexamine tablets, which contain flammable elements of formaldehyde, ammonia, nitrogen oxide and hydrogen cyanide. Associated tablets have been removed from collection as a safety precaution. Due to the fumes of the fuel tablet, food cooked on such a stove would have been sealed in a container when cooking.Silver coloured aluminium hexamine stove. The stove is made of three pieces of metal, the 'floor' and two sides, which form a box when closed and when open appear like an upturned table. The floor of the stove has a series of holes and lines stamped into it. The sides of the stove have been attached to the base with brass rivets. When open, the sides open to form a stand at the base and the interlocking grooves which line the edges of the sides act as a cooking platform on top. When closed, the stove appears as a small box. cooking, vietnam, field, equipment, rations, food, 1960s

First available in ScubaPro’s catalogue in 1966, the ScubaPro Automatic Decompression Meter was a break through in diving technology and a forerunner to the modern dive computer. The meter attempted to calculate nitrogen absorption based on dive time and depth. This was done mechanically instead of electronically, and without the benefit of any actual computing. The Automatic Decompression Meter was introduced just a year after ScubaPro’s most successful product – the ScubaPro Jet Fins – which still remain popular today.

When Hewitt introduced his regulating stopcock in 1887, attempts were made to dilute the nitrous oxide with air and so obviate the element of asphyxiation. The method was to be seen in London, mainly in dentistry and minor surgery, so late as 1930. It was not very successful. To give even 10% of oxygen (which is not enough) the gas-mixture must contain 55% of air and 45% of nitrous oxide. The latter is thus so diluted by atmospheric nitrogen as to be incapable of producing anaesthesia except by asphyxiation. "Gas-air" was confined to analgesia, for example in midwifery.

The Albion Explosives Factory began as Commonwealth Defence Explosives Annexe No. 5, constructed rapidly in 1939–1940 as part of Australia’s WWII munitions expansion. It was built adjacent to the long‑established Nobel / ICI explosives works at Deer Park and produced TNT, nitroglycerine, cordite, RDX, DNT, and related explosive compounds. This plant manufactured Research Department Explosive (RDX), a nitrogen‑rich high explosive used in military munitions, which is far more powerful than TNT, yet relatively stable to store and transport. It is not a consumer or industrial product and sits firmly in the defence materials category.This series of time elapsed photographs records the demolition of the Northern RDX Acid Plant chimney by controlled demolition by explosive which safely brought the chimney down by making it to fall to one side. The history of the Albion Explosive Factory is tightly connected to the evolution of the Deer Park explosives precinct and the wider ICI industrial township.Chimney Blown Up Explosive Factory Deer Parkalbion explosive factory, ballarat road, deer park, ici

Home is a collection of birdhouses on floating islands using the iconic form of the human house - a pitched roof, square walls, windows and doors. This minimal form is often drawn by children; a dolls house, a cubby house, a letter-box or a chook house. Home creates a safe refuge for birds with the plants acting as a water filtration system. The exposed roots draw out pollutants, such as nitrogen, phosphorous and toxic metals, which have entered the waterway through urban run-off. The result is a beautiful sculptural experience and a healthier water system for all to enjoy. The artwork was funded by The City of Ballarat and The Victorian State Government.The work is of aesthetic significance to the people of BallaratHome is a collection of birdhouses on floating islands home, chris mether, studio mether, public art, ballarat, delecombe, wetlands

Seems to be a non- collapsible mask. Otherwise is a similar, thinner variety of Murray's mask, which was used for the administration of choloroform. John Murray was born in England, 1843 and described his wire mask in 1868 as a young chloroformist at Middlesex Hospital. It was wedge-shaped and made of thick wire and designed to be folded. The removable cover was originally made of several layers of flannel. Murray’s mask became very popular, especially in Australia, and was generally used with a single layer of flannel without an aperture or opening, as is this example. John Murray was an enthusiastic and innovative physician who also had an interest in nitrous oxide anaesthesia and conducted a series of experiments with J. Burdon Sanderson on dental patients comparing nitrous oxide to pure nitrogen. His career was short-lived and he died just before his 30th birthday. (Ball, C 1995, 'Cover Note: Murray's Chloroform Mask', Anaesthesia and Intensive Care, Vol. 23, No. 2, pg. 135)Triangular shaped wire mask covered by flannel. The flannel is sewn over frame and stitched around the base and along the vertical wire. The style and shape is similar to Murray's mask, which was used for the administration of chloroform, however this variation is not collapsible like Murray's mask.dr [e.s] holloway, mask, dr j. murray, chloroform

The author, Georges M. Ville (or George M Ville) was a French agriculturalist and botanist who lived from 1824-1897. His career began as a pharmacist and he is known for his research and experiments on the effects of nitrogen and chemical fertilisers on plants, mostly on his experimental farm, He wrote several books in his field of work. The book is part of Flagstaff Hill's Pattison Collection, a large group of books and records, some of which are rare and valuable. The collection was owned by the Warrnambool Mechanics' Institute, founded in 1853, and is named after Warrnambool's Public Librarian, Ralph Pattison. The handwritten comment on the fly page infers that the book was purchased by a Government subsidy in May 1910 and received in that same month. The book's publisher, Longman, Green & Co. was originally established by Thomas Longman founded his publishing firm in 1724 in London by the name Longman. In August of that year, he bought the two shops and goods of William Taylor and set up his publishing house there at 39 Paternoster Row. The shops were called Black Swan and Ship, and it is said that the 'ship' sign was the inspiration for Longman's Logo. After many changes of name and management, the firm was incorporated in 1926 as Longmans, Green & Co. Pty Ltd. The firm was acquired by Pearson in 1968 and was known as Pearson Longman or Pearson PLC. The Pattison Collection, along with other items at Flagstaff Hill Maritime Village, was originally part of the Warrnambool Mechanics' Institute’s collection. The Warrnambool Mechanics’ Institute Collection is primarily significant in its totality, rather than for the individual objects it contains. Its contents are highly representative of the development of Mechanics' Institute libraries across Australia, particularly Victoria. A diversity of publications and themes has been amassed, and these provide clues to our understanding of the nature of and changes in the reading habits of Victorians from the 1850s to the middle of the 20th century. The collection also highlights the Warrnambool community’s commitment to the Mechanics’ Institute, reading, literacy and learning in the regions, and proves that access to knowledge was not impeded by distance. These items help to provide a more complete picture of our community’s ideals and aspirations. The Warrnambool Mechanics Institute book collection has historical and social significance for its strong association with the Mechanics Institute movement and the important role it played in the intellectual, cultural and social development of people throughout the latter part of the nineteenth century and the early twentieth century. The collection of books is a rare example of an early lending library and its significance is enhanced by the survival of an original collection of many volumes. The Warrnambool Mechanics' Institute’s publication collection is of both local and state significance.

The nine postcards in this set were donated together and date to the early 1900s. All but one postcard in this set shows images of Warrnambool, in the Western District of Victoria; the other has a London image. The postcards were all printed in Great Britain according to that country’s postal regulations. The fronts of all cards have titles printed in red. Most of the images on the cards are attributed to photographer Joseph Jordan and belong to the Jordan Series. The back of these cards has an outline for a postage stamp, a vertical dividing line and a heading on each side of the line to separate the Correspondence from the Address. Postcards or ‘correspondence cards’ appeared in Britain in 1894. They were plain cards with a space for the message on one side and an address on the other; regulations didn’t allow anything but the address to be written on the ‘address’ side. In 1902 the British regulations then allowed a picture to be printed on the front and the address on the back, so messages had to be written on the picture side. Soon, the regulations changed and the back was divided for a message and the address. Pliiar Caves, near Warrnambool – The formation at the front of the cave resembles the pillars of a porch, giving the cave its name. Local social media discussion locates the caves near Lake Gillear, east of Warrnambool. The area was popular with young lads as a place to explore and to go rabbiting. The caves in this area are home to colonies of bats and have been a source of bat feces or bat guano, which is an enriching additive to soil. The 19th century sailing ships in the Nitrogen or Guano trade collected large quantities of guano from caves and popular bird nesting locations to sell as a rich fertiliser, due to its high nitrogen and phosphorus properties. Joseph Jordan - Joseph Jordan was born in 1841 in Leicester England. When he was 16 he joined the 7th Queen's Own Hussars and was sent to India at the outbreak of the mutiny. He took part in the relief of Lucknow and remained in India for eleven years. It was during this time that he became interested in photography. He was posted to New Zealand and later came to Victoria, becoming a sergeant major of the Mounted Rifles. In the mid-1880s he came to the Western district where he was responsible for establishing units of the Mounted Rifles in various country towns such as Dunkeld, Mortlake, Panmure, Bushfield, Koroit etc. He resigned from the army in 1889 and set up a professional photography studio in Liebig Street, Warrnambool. He became very well known in the Western District for family photographs, official photographs of local councillors and groups as well as views of local scenery. In 1891 he photographed the wrecked barque ‘Fiji’ at ‘Wrecks Beach’ near Princetown. His business was taken over by his son Arthur around 1917. Joseph was a keen rifle shot and in 1924 he donated the "Jordan Shield" as a prize to the Victorian Rifle Association. He was made a "Life Honorary Member" of the Warrnambool Returned Soldiers League and in 1933 he was recognised as being the oldest living soldier in Victoria. Joseph died in 1935 aged 95.The image of the Pillar Caves rock formation with figures on it suggests that the location was a popular place to visit. The choice of subject for this postcard indicates the popularity of Warrnambool's natural environment as a tourist attraction at a time when ships called coastal traders brought passengers and cargo to the Port of Warrnambool from ports along Victoria's southwest coast. The presence of bats in local caves also connects the postcard to the 19th century Nitro Trade and Guano Trade, when bat guano was collected and sold for plant fertiliser around the world. Joseph Jordan is a significant figure in Warrnambool history as he helped to establish early units of the Mounted Rifles (G Company) in local towns during the late 1880's and later, photographed local scenes, groups and citizens of early Warrnambool.Postcard, one of nine, landscape orientation, coloured print within an oval border and mauve-toned shading. The cameo image shows figures on the high, grass-topped cliff, one between the likeness of pillars in the cave entry, and others walking on the rocks nearby. The background below is rough ground.

Louis Heinrici, Germany, circa 1900 a small Stirling type hot air engine in which a body of air is worked constantly, being alternately heated and cooled during each revolution of the crankshaft. Heinrici hot air engines are of the valveless, closed cycle type, generally called Stirling cycle engines, after Robert Stirling, the Scottish Presbyterian minister who pioneered their development in the early 1800's. They operate by alternately heating and cooling a quantity of air, called the working fluid, contained in the engine's internal spaces. Heat is applied externally and passes through the cylinder wall, heating the working fluid, which is then expanded against a piston to do mechanical work. After heating and expanding, the working fluid is moved to a cool space where it cools and contracts before being returned to the hot space for the cycle to repeat. It has a displacer (just a loose piston), below and in the same cylinder as the power piston to which it is connected via cranks and linkages so as to lead by 90degrees of crankshaft angle. The displacer space and the piston space are connected by the annular gap around the loose fitting displacer so that the working fluid moves between these spaces and changes volume by the appropriate ratio as the engine rotates. Because they have no valves and experience no sudden pressure changes, Stirling engines are noted for quietness and reliability. Heinricis use air at atmospheric pressure for their working fluid, but for higher specific output (power for size) and better efficiency, modern Stirling cycle engines use pressurised gas- air, nitrogen, helium or hydrogen.Historic - Hot Air Engine - MotorHot Air Motor made of Steel with two drive wheels. a small Stirling type hot air engine in which a body of air is worked constantly, being alternately heated and cooled during each revolution of the crankshaft.
