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.

This Non-return valve was recovered from the wreck of the Newfield. Non-return valves can be used to pump water out.of a vessel The barque Newfield left Liverpool on 1st June 1892 with a cargo of 1850 tons of fine rock salt for Brisbane. About six weeks later the ship ran into very heavy weather approaching the Australian coast. On 28th August at about 9pm her master, Captain George Scott, observed between the heavy squalls the Cape Otway light on the mainland of Victoria, but due apparently to a navigational error (the chronometers were incorrect), he mistook it for Cape Wickham on King Island, some 40 miles south. He altered course to the north expecting to run through the western entrance of Bass Strait, but instead, at about 1:30am, the ship ran aground about about 100 yards from shore, one mile east of Curdies River. The vessel struck heavily three times before grounding on an inner shoal with six feet of water in the holds. The Newfield remained upright on the reef with sails set for a considerable time as the wind slowly ripped the canvas to shreds and the sea battered the hull to pieces. Seventeen men survived the shipwreck but the captain and eight of his crew perished.Flagstaff Hill’s collection of artefacts from the Newfield is significant for its association with the shipwreck Newfield, which is listed on the Victorian Heritage Registry. The collection is significant because of the relationship between the objects. The Newfield collection is archaeologically significant as the remains of an international cargo ship. The Newfield collection is historically significant for representing aspects of Victoria’s shipping history and its association with the shipwreck.A non-return valve used to connect to a hose on a bilge pump on a vessel.

When the ship Schomberg was launched in 1855, she was considered the most perfect clipper ship ever to be built. James Blaine’s Black Ball Line had commissioned her to be built for their fleet of passenger liners. At a cost of £43,103, the Aberdeen builders designed her to sail faster than the quick clippers designed by North American Donald McKay. She was a three masted wooden clipper ship, built with diagonal planking of British oak with layers of Scottish larch. This luxury vessel was designed to transport emigrants to Melbourne in superior comfort. She had ventilation ducts to provide air to the lower decks and a dining saloon, smoking room, library and bathrooms for the first class passengers. At the launch of Schomberg’s maiden voyage, her master Captain ‘Bully’ Forbes, drunkenly predicted that he would make the journey between Liverpool and Melbourne in 60 days. Schomberg departed Liverpool on 6 October 1855 with 430 passengers and 3000 tons cargo including iron rails and equipment intended the build the Geelong Railway and a bridge over the Yarra from Melbourne to Hawthorn. The winds were poor as Schomberg sailed across the equator, slowing her journey considerably. She was 78 days out of Liverpool when she ran aground on a sand-spit near Peterborough, Victoria, on 27 December; the sand spit and the currents were not marked on Forbes’s map. Overnight, the crew launched a lifeboat to find a safe place to land the ship’s passengers. The scouting party returned to Schomberg and advised Forbes that it was best to wait until morning because the rough seas could easily overturn the small lifeboats. The ship’s Chief Officer spotted SS Queen at dawn and signalled the steamer. The master of the SS Queen approached the stranded vessel and all of Schomberg’s passengers were able to disembark safely. The Black Ball Line’s Melbourne agent sent a steamer to retrieve the passengers’ baggage from the Schomberg. Other steamers helped unload her cargo until the weather changed and prevented the salvage teams from accessing the ship. Local merchants Manifold & Bostock bought the wreck and cargo, but did not attempt to salvage the cargo still on board the ship. They eventually sold it on to a Melbourne businessman and two seafarers. After two of the men drowned when they tried to reach Schomberg, salvage efforts were abandoned.32 In 1975, divers from Flagstaff Hill, including Peter Ronald, found an ornate communion set at the wreck. The set comprised a jug, two chalices, a plate and a lid. The lid did not fit any of the other objects and in 1978 a piece of the lid broke off, revealing a glint of gold. As museum staff carefully examined the lid and removed marine growth, they found a diamond ring, which is currently on display in the Great Circle Gallery.33 Flagstaff Hill also holds ship fittings and equipment, personal effects, a lithograph, tickets and photograph from the Schomberg. Most of the artefacts were salvaged from the wreck by Peter Ronald, former director of Flagstaff Hill. The Schomberg, which is on the Victorian Heritage Register (VHR S612), has great historical significance as a rare example of a large, fast clipper ship on the England to Australia run, carrying emigrants at the time of the Victorian gold rush. She represents the technical advances made to break sailing records between Europe and Australia. Flagstaff Hill’s collection of artefacts from the Schomberg is significant for its association with the shipwreck, The collection is primarily significant because of the relationship between the objects, as together they have a high potential to interpret the story of the Schomberg. It is archaeologically significant as the remains of an international passenger Ship. It is historically significant for representing aspects of Victoria’s shipping history and for its association with the shipwreck and the ship, which was designed to be fastest and most luxurious of its day Valve, non-returning.

The Fluotec vaporizer was made to administer only halothane (Fluothane). It was one of the first vaporizers made for use with only one anesthetic, and one of the first to use a bimetallic coil for temperature compensation.The bimetallic coil is part of the valve that controls how much of the carrier gas enters the vapor chamber to vaporize the anesthetic.Modern vaporisers still use this bimetallic coil technology today. Serial No: 5040 Patent No: 814427 A ready reference “calibration card” came attached to these vaporizers. The card was printed with a scale that indicated the concentration of halothane produced at different flow rates and dial settings.This item does not have a reference card with it.This Flotec vaporiser holds historic significance as a very good example of an early model piece of equipment for halothane only administration.

This model was found in the collection of Bay Steamers Maritime Museum. It is not knowt who created it but it is supposed that it was constructed to educate the many masters of the Wattle in the operation of a steam engine - a not so common mode of power these days. A Bay Steamers Maritime Museum examined the model in March 2012 and discovered that is was in poor repair. Using his existing knowledge, and with reference to some historic texts, he made some repairs and returned the model to working order. Here is his anaylsis of the situation as an excerpt from the Bay Steamers Maritime Museum newsletter Steamlines May 2012 "I was confronted with a model of a steam engine used years ago as a training aid for hopeful steam engineers. Already having a knowledge of steam operations, I considered a museum write-up for that model a ‘piece of cake’. However, on turning the model’s crankshaft, the valve timing seemed ‘out of kilter’ with the movement of the piston. Problem was that the two eccentrics on the crankshaft were not properly secured to it. Eventually I fastened the two eccentrics to the crankshaft where I felt that they should be and then realized that one of them had a chain-driven valve-timing device attached. This would be adjusted while an engine was running to achieve best performance and fuel economy whilst in operation by accurately controlling the period of time during which steam under pressure from the boiler would be admitted to the cylinder and give greater time for the steam to expand in the cylinder, move the piston and turn the crankshaft and thus, drive the attached apparatus. When the valves were correctly set up it was then possible to get the model to function properly.The model comprises a green section, which is the actual the model mounted on a brown painted board. There are two parts of the model, painted white representing the steam passages, and black representing the cast- iron portions of the cylinder-block casting, and of the main valve sliding between the cylinder a second sliding valve. Of the black portions, one slides back and forth being connected to a rod which is connected to an eccentric clamped to the crankshaft and is the nearer to the flywheel of two eccentrics. This eccentric is attached to the crankshaft at an angle of 90 degrees to the crank-pin attached to the flywheel. To operate the model simply turn the flywheel by means of the handle attached to its crank-pin. A second eccentric is also attached to the crankshaft, further away from the first eccentric, and it is adjusted to operate 90 degrees from the first eccentric (that is, 180 degrees from the crank-pin) A piston (painted silver) is located in a plastic cylinder and has a piston rod which passes through one end of the cylinder, (in actual practice a steam-proof gland seals the cylinder against loss of steam) terminating in a cross-head slide between four rails guiding it. From this cross-head, a connecting rod joins the piston-rod to the flywheel via the crank-pin attached to the flywheel which is part of the crankshaft. (In actual practice, a flywheel may not be used, particularly in a multi-cylinder engine.) The white portions of the model painted nearest to the cylinder represent the two steam ports cast into the main cylinder block, whilst one section painted in between those two represents the exhaust outlet (which may be connected to a condenser to conserve water, or to the open air). The main slide valve has three white-painted portions painted thereon. It has two white-painted marks representing the steam passages to the steam ports into the cylinder, and a third section in between the other two, being that part of the valve through which exhaust steam passes in line with the ports in the cylinder block. By rotating the flywheel, the operations of an engine will be observed as steam is admitted to the main valve via the gap between the two jaws of two moveable portions of a second sliding valve which is operated by the second eccentric attached to the crank-shaft. This eccentric is used to finely tune the valve timing of this model to obtain best running results of an engine. There are various methods used for reversing a steam engine. model compound steam engine, steam engine, model, crankshaft, valve, flywheel, wattle, engineer, eccentrics
