The Junction Dam and Clover Dam Power Station, stages of the Kiewa Hydro-Electric Scheme, were needed to meet the increased power demands of the wartime industry in Victoria. Clover added 26 megawatts to the grid. Junction Dam was completed and ready to hold water by September 1943, but was emptied in December 1943 and not filled again until May 1944. Construction of Clover Power Station commenced in July 1941 and both turbines were in service by May 1945Clover Power Station and Junction Dam were part of the Kiewa Hydro Electric Scheme constructed by the State Electricity Commission of VictoriaSet of 21 black and white photographs taken by the official SECV photographer who gave each photo a number prefixed by K (for Kiewa) K1463- 22 Mar 1944 Inside Clover Power Station K1464- 23 Mar 1944 Valve K1466- 23 Mar 1944 Fittings for the power station K1467- 23 Mar 1944 Valve K1472- 30 Mar 1944 Equipment being installed in Clover Power Station K1474- 31 Mar 1944 Equipment for the power station K1493- 19 April 1944 Transformer K1495- 28 April 1944 Part of the generator being installed K1514- 11 May 1944 Equipment in the power station K1563- 9 June 1944 Turbine under construction K1565- 22 June 1944 Shaft between turbine and generator K1567- 22 June 1944 Turbine in the power station K1568- 22 June 1944 Transformers K1570- 5 June 1944 Guide vane actuators K1574- 22 June 1944 Equipment in the power station K1567- 22 June 1944 Clover Power Station K1607- 14 Aug 1944 Equipment in the power station K1620- 27 Aug 1944 ‘Charles Tavare (?)

Lambert Ormsby was a New Zealand surgeon who migrated to Ireland. He described his inhaler in a letter to the Lancet in 1877.Ormsby listed the advantages of his inhaler as simple, inexpensive, small quantity required to produce sleep, prevents evaporation of ether, portable and small (can be carried in pocket), short time to complete anaesthesia (two minutes) and safe. Disadvantages of this apparatus were that it had to be removed in order to recharge the sponge with ether or when anaesthesia becomes too deep. Considerable carbon dioxide accumulation developed and there would also be some oxygen lack. In thirty years of use, Ormsby's Inhaler underwent certain modifications, an exhalation valve was fitted to the mask and device for recharging the sponge with ether was later added. The Ormsby inhaler was modified by Carter Braine in 1898 with the aim of making it easier to clean. Essentially it is very similar except there is no net around the bag.The inhaler consists of an india-rubber flexible bag enclosed within a net bag to limit expansion. There is a soft metallic mouthpiece with india-rubber tubing around the edge. The tubing had to be purchased separately from the manufacturer. The body contains a wire cage with a similarly shaped hollow sponge into which ether was poured.Maker's details inscribed into metal ring around the bore: Barth Co.

This is an early example of the Boyle's Anaesthetic Machine which was to become widely used throughout the world. The plaque on the wooden plinth suggests it was a display model from the medical equipment distributor Charles A King of London.The gas anaesthesia apparatus is mounted to a rectangular wooden base. It comprises two long, vertical glass cylinders held in place with metal brackets which are connected to a glass chloroform vaporiser container via metal tubes and associated valves and connections. The bottom of the glass flasks have outlet connections and inscriptions on the glass to measure volume. The chloroform vaporiser and adjacent glass ether vaporiser also have volume measurements etched on the glass, and the latter is the same height as the former but is larger in diameter. Both are connected via metal tubes and include outlet pipes that have associated cork stoppers. The maker's details are provided on a brass plaque attached to thewooden platform.A. Charles King Ltd.

BY THE time the FJ Holden was replaced with the FE in July 1956, Australia’s own had taken many steps forward. The six-volt electrics were replaced with a 12-volt set-up, the two-piece windscreen was replaced with a single curved item and the skinny 15in rims were replaced with 13x4.5 steelies. Unlike the FX-FJ, the FE was designed locally by an Australian team. The resulting car was much sleeker than the earlier models, being two inches longer in the wheelbase, four inches longer overall and slightly heavier than its predecessor. To compensate, the 132ci grey motor was blessed with another small dose of horsepower thanks to larger valves and improved cylinder heads. Other mechanical improvements included pendulum-style brake and clutch pedals, hydraulic clutch actuation, larger brake drums and recirculating ball (rather than worm and sector) steering. Other great leaps forward included optional heater, indicators, reversing lights, windscreen washers and demister. In knocked down form was the first model to be exported to New ZealandBlack painted special sedan. Added accessories include exterior sun visor, headlight protectors, and on the interior grab handle mounted across the back of the front seatDiecast special sedan badge on rear quarters.

The Ferranti Sirius is an electronic second-generation transistor computer and is one of three remaining examples of this machine left in the world. It was an important addition to the computing facilities at Monash University in the early 1960s and provided access for computer programming and research for many early computer professionals, academics and teachers. The Ferranti Sirius computer was built in a period of rapid growth in computing technology. The first stored program computers appeared in the late 1940s and used individual designs with valve technology. By the mid-1950s valve technology was replaced by transistors and the first mass produced commercial computers became available. The Ferranti Sirius was announced in 1959 and offered a “small” academic computer. It was designed and built by the English company Ferranti Ltd and sold through a local office of the company in Melbourne. The Sirius was manufactured at the Ferranti Ltd.’s West Gorton, England factory from 1959 to 1963 and, in all, the company produced probably 22 installations although only 16 were actually recorded as sold; this included one at Ferranti’s Bureau in London and one at Ferranti’s Melbourne Bureau. Only 7 were exported and 4 of these 7 were located in Melbourne, Australia. All four were associated with computing at Monash University – the Sirius in the MMoCH collection was purchased by Monash University in 1962, a smaller Ferranti Sirius was used on the Caulfield campus (prior to amalgamation with Monash University) from 1963, the Ferranti company had its own Ferranti Sirius initially temporarily installed at Clayton campus in 1962 and then placed in their office in Queens Road, Melbourne. A fourth computer was purchased by ICIANZ (now Orica) in 1962 and was transferred to Clayton campus in 1967. Only two of these Melbourne examples have survived; one in the MMoCH collection and one at Museums Victoria. There is an example of the Ferranti Sirius in the Science Museum Group collection in the UK as well. The Ferranti Sirius in the MMoCH collection was the first computer purchased by Monash University and it was shipped to Australia to be installed by November 1962. The University had a similar model computer on loan from Ferranti Ltd during the first part of the year and it was returned to the office of the company in Queens Road, Melbourne once the University’s own machine was installed. The computer was placed on site at Clayton campus, Monash University. The computer operated from 1962 until 1972 when it was officially decommissioned. The Ferranti Sirius was sold to Mr Paul Stewart in late 1974 and removed from Monash University. Mr Stewart later donated the computer back to the University in 1988 and it was transferred to the collection of the Monash Museum of Computing History after 2001. The Ferranti Sirius is an electronic second-generation transistor computer and is one of three remaining examples of this machine left in the world. It was an important addition to the computing facilities at Monash University in the early 1960s and provided access for computer programming and research for many early computer professionals, academics and teachers. The Ferranti Sirius is of scientific (technological) significance as one of the early transistor digital computers that transitioned computing from first-generation valve computers to second generation commercial installations. This example of the Sirius is of historical significance in its role as a part of the Computer Centre, Clayton campus, Monash University which provided computing facilities in Melbourne in the early 1960s when there were few installations available for academic, administrative and commercial users. Staff and students were able to undertake investigative research and learn programming techniques. The Computer Centre encouraged the use of the computer across all disciplines and this provided the base to establish computer science as a subject offering and, later, a new department in the University. This growth in computer education eventually culminated in the establishment of the Faculty of Information Technology, Monash University. The Ferranti Sirius in the collection at Monash Museum of Computing History has a main unit with a CPU and memory combined with input/output equipment and one extra cabinet of memory. The Central Processing Unit is a floor-standing unit which contains the computer circuits, power supplies and has a decimal digit display panel and a normal clock. A moveable control panel is placed in front of the Unit (Currently set on a recreated desk/filing cabinet support in the display). The Sirius base unit uses acoustic delay line memory with 1000 word store. An additional 3000 word memory cabinet is set adjacent to the CPU and can be connected to increase the memory. The computer is supported by a range of input/output devices. There is a Ferranti Paper tape reader, located on desk in front of CPU. Red label on front “Ferranti tape reader. Type TR 5. Serial No. 477”. Adjacent to the CPU is a set of Simplified tape editing equipment in three pieces which includes a (1) Table unit with switches on front face. Metal tag on reverse reads “Creed & Co. Model No. S4060. Serial No. 1457. Original Customers Marking GRP7 V706”. The table has a numbered internal tag “Table Serial No. 198579. (2)Creed teletype set on table unit. Metal tag on reverse “Creed & Co. Model No. 75RPR K4M4. Serial No. 5897 Made in England”. (3)Creed paper tape reader set on table unit. This set of equipment could read paper tape and print it, or copy paper tape while allowing it to be edited, or allow a programmer or data preparation person to type and punch a new program or data. It has no electrical connection to the computer. Paper tapes were usually torn off and carried across to the computer. There is also another table unit with switches on front face and changeable setting switch on front right side which holds a Ferranti Westrex paper tape punch set. Label on reverse “Teletype Code BRPE11” This was the Computer’s only output device. BRPE-11 is a teletype model number.

From the Imperial War Museums website (IWM UK): Second World War period transceiver set widely used by US, and Allied, Armed Forces in Italy, N W Europe, and the Pacific. The US Signal Corps developed the SCR-536 early in the Second World War, It was produced from 1942 onwards by the Galvin Manufacturing Co. By 1945 130,000 had been produced. The SCR-536 was an extremely popular set and was colloquially known as a "Handie-Talkie". It consisted of a five-valve, low-power, battery operated, AM (HF) transceiver that was designed for portability and ease of operation. It featured a single channel crystal control between 3.5 and 6Mc/s, and it had an R/T communication range of 1 mile over land and 3 miles over salt water. The set was switched into a receiving mode by extending the telescopic aerial, and to transmit the press-to-talk switch was depressed. The aerial was protected by a connected cover. The set was well-engineered and designed and could be held in one hand, hence "Handie-Talkie" . It was used virtually everywhere in the world, weighed only 2kg, and was proofed against fungi and moisture.The SCR-536 was also modified for use in military gliders under the designation SCR-585.Short range portable transceiver. A large green-painted metal box with perforated small round holes in the shape of hexagons (original perforated round black earpiece and mouthpiece missing).

The Davey Paxman Experimental Steam Engine was purchased as the result of a bequest from Thomas Bath. The 'substantial sum' was used to build an Engineering Laboratory. The Ballarat School of Mines Council minutes of 08 November 1901 record: - Plans for [the] proposed building were submitted ... and ... it was resolved that a temporary building for an Engineering Laboratory be put up.' This laboratory, as an existing building, is first mentioned in the Ballarat School of Mines President's Annual Report of 1901, presented on 28 February 1902, reporting 'the erection of a building 67ft long by 33 ft wide' This report also lists all the equipment that would be accommodated in the Engineering Laboratory, including the experimental steam engine and boiler. The experimental Davey-Paxman steam engine arrived in Ballarat towards the end of 1902. The Engineering Laboratory was opened on 14 August 1903 by His Excellency Sir Sydenham Clarke. This engineering laboratory remained in use till about 1945. By 1944 preparations were under way at the Ballarat School of Mines to expand existing facilities, to be ready for the influx of returned soldiers. A new Heat Engines laboratory was built, this time of brick construction, replacing the previous corrugated-iron shed. In the early stages the steam engine was used to drive an overhead transmission shaft for machinery in the adjacent workshop. Later the steam engine was moved to a space that became the Heat Thermodynamics Laboratory. At the end of 1969 the engine was relocated to the Thermodynamics Laboratory at the then Ballarat Institute of Advanced Education (BIAE) Mt Helen Campus. It was donated to Sovereign Hill in 2006. According to the research of Rohan Lamb in 2001 around five experimental steam engines were made by Davey Paxman, and three of these had similar configuration to the Ballarat School of Mines Steam Engine, however, each of these was also unique with different valve arrangements. The list, which was on a scrap of paper in a folio held in the Essex Archives, confirmed that one was sent to India. The Ballarat steam engine can be dated to late 1901 to early 1902. Zig Plavina was responsible for moving the steam engine to Mount Helen, and worked on it as a technician for many years. He observed the following: * The condenser is driven by the low pressure engine. * The following arrangements are possible: i) the high pressure engine alone, exhausting to atmosphere. Condenser not used, crankshaft flanges not coupled. ii) crankshafts coupled, mains pressure (120 psi) steam supplied to high pressure engine, partially expanded steam delivered to low pressure engine (Tandem operation). Choice available re exhaust steam: either to the condenser or to atmosphere. iii) crankshafts not coupled, reduced pressure steam supplied to low pressure engine. Exhaust steam - either to the condenser or to atmosphere. * Valve arrangement - a choice of Pickering cut-off or throttle governor. On low pressure engine - throttle governor only.Black and white photograph of the Davey Paxman Experimental Steam Engine.
