'Calcium Borogluconate ia a stable , non-irritant calcium preparation for subcutaneous or intravenous injection in the treatment of milk fever and other forms of acute hypocalcaemia. It is available in the dry state as 'Wellcome' Calcium Borogluconate, a granular product in single dose containers of 2 1/2 oz. Milk Fever In the treatment of milk fever in cows, 21/2 oz. to 31/2 oz. of the granules should be injected subcutaneously at two or three points in the neck, with the usual aseptic precautions. The granules should be dissolved in 10 fl. oz. of boiling water, the solution allowed to boil for five minutes, then cooled to body temperature before administration. Repetition of the dose is very rarely necessary. Should a more rapid response be desired, the whole of the solution hay be given by slow intravenous injection; alternatively , the greater part of the solution may be injected by this route and the remainder given subcutaneously in the manner described above. A convenient apparatus for the controlled administration of large volumes of fluid (leaflet side two) is the 'Wellcome' Flutter Valve Injection Apparatus. Prophylaxis Recurrent attacks at successive parturitions may be prevented by giving calcium borogluconate immediately after calving and again about 20 hours later. Each dose should be from one or two ounces of 'Wellcome' Calcium Borogluconate, dissolved as directed above. Other Indications Certain other conditions have been found to respond readily to calcium borogluconate therapy. These include parturient hypocalcaemia or milk fever in ewes, parturient eclampsia in sows and bitches, so-called "staggers" in lactating dairy cattle suspected to be due to hypocalcaemia, and transit tetany in horses. The dosage for various species is generally within the ranges indicated below : horses and cattle 11/2 to 31/2 oz. Sheep, goats and pigs 1/2 oz. to 1 oz. Dogs 11/2 dr. to 3 dr.

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

In 1913, Mark Cowley Lidwill designed a machine for the purpose of mechanical or insufflation anaesthesia. The Lidwill machine was a portable machine weighing 7kg that could easily be packed into two small bags. The machine involved compressed air being delivered to an ether vaporiser. An ether/air control device allowed varying concentrations of ether to be delivered. The ether vaporiser could be immersed in hot water to prevent cooling and the ether temperature was measured. From the vaporiser, the ether/air mixture went through a trap bottle, then to a crude mercury blow-off valve and subsequently to the patient.Large leather suitcase style bag divided into two levels containing and insufflation anaesthesia machine.insufflation, mark cowley lidwill, thoracic surgery, positive pressure

The Lister Auto-Truck was a small monowheel tractor built for moving light loads around factories, railway yards and similar sites. They were built by R A Lister and Company of Dursley, Gloucestershire, well known for their range of small stationary engines The Auto-Truck was one of several monowheel tractors to appear in the 1920s and '30s, with the availability of small, reliable petrol engines, as developed for motorcycles and the stationary engines for which Lister were already known. These were tricycle vehicles, with the single leading wheel used for both drive and steering. Their simple construction carried most of the mechanism on this wheel as a single unit, the chassis with the trailing wheels being little more than a trailer for balance. Simplicity was a key feature. The engines were single-cylinder and air-cooled. Ignition was by magneto, rather than requiring a battery and electrical system. One of these designs was produced in the 1920s by George Grist of the Auto Mower Co., Norton St Philip, Somerset. The engine was a JAP 600 cc four-stroke air-cooled sidevalve, a typical small engine of the time. The Auto Mower Co. were Lister agents and when Lister heard of this 'Auto-Truck' they bought one for use in their own factory. It was used to carry heavy engine castings from the foundry to the machine shop. Lister customers saw them and there was such interest in wanting to buy them that Lister negotiated with Auto Mower to build them under licence. Although Lister were already well known for their small petrol stationary engines, these were heavy cast-iron engines with water hopper cooling and unsuitable for vehicle use. Lister remained with the JAP engine for the Auto-Truck. The Auto-Truck was designed for use in factories or other places with smooth surfaces of concrete or tarmac. This allowed the use of small solid-tyred wheels with only simple suspension, making the vehicle simple, cheap and lightweight. They had little ability on soft surfaces though and could even topple over if driven carelessly across slopes. Their design was a compromise between the top-heavy nature of the tall engine grouping above its wheel and a well thought-out chassis for stability. The bearing between them was a large diameter ring roller bearing, mounted at the lowest part of the chassis. This gave rigidity and stability, even after long wear. A ring of rolled channel girder was attached to the engine group and rollers on the chassis carried the load upon this. On early Auto-Trucks this bearing is set very low, in line with the chassis members, and is covered by thin steel plates. The front panel of the engine cover is distinctive with large ventilation holes and a Lister signature cut through it. Strangely this panel is made of thick cast iron, providing substantial weight high on the engine and only adding to its top heaviness. To improve visibility of moving vehicles in noisy factories, this panel was often painted white, the rest of the vehicle being Lister's usual brunswick green. The driver was seated on a Brooks bicycle saddle, which in recognition of the lack of vehicle suspension, was carried on the end of a cantilevered bar that acted as a leaf spring. A wide handlebar on the engine group was used for steering. A squeeze bar the width of this handlebar engaged the clutch. Controls included a hand throttle, a gear lever with two forward and one reverse gears, and a large handbrake lever. The engine unit rotated freely for a full 360° rotation. When used in reverse, the Auto-Truck could either be driven from the saddle, looking backwards over the driver's shoulder; or they could dismount, swivel the engine unit around and control it as a pedestrian-controlled truck from behind. Under the engine cover were two equal diameter tanks, a fuel tank for petrol and a shorter oil tank. Engine and chain-drive lubrication used a total-loss oil system, controlled by a small pump and needle valve.

The origins of the humble handheld driptorch have been lost in time. They are widely used for ignition in controlled burning operations in forest and grasslands. The “Pacific Forester“ with its short central wand and somewhat leaky ball-valve was made by the American Wajax company in the 1940s. The Pacific Forester is slightly different in design from the more robust and common “Panama” driptorch first manufactured in 1933 and used extensively by Queensland cane farmers. The Panama is closely related to the current “Firebug” used in Victoria which is manufactured by Rodney Industries in Brisbane and has an offset wand design which gives it good balance. The fuel is a mixture of petrol and diesel and every FCV District had their own closely-guarded secret formula ... 2:1, 3:1, 1:1, 4:1 or 3:2 ratio. There was also the choice of 91, 95 or 98 octane petrol mixed with summer or winter diesel. Occasionally some of the old Avgas or Jet-A1 lying around the depot was added with a splash of engine oil to make the mixture stick to the fuel to be ignited. The fuel mixed also varied between autumn or spring, heathland, mixed forest, or high-intensity slash burnsCommon driptorch used throughout AustraliaDrip torch with handle Wand has loop and valve. The loop is designed to assist with even flow of fuel which flows out onto the burning head of the wand.

Japanese style box bellows (fukisashi/吹差鞴) reached their current and finalized form by about the sixth century. They are constructed almost entirely of wood and allow a smith to supply a highly controlled air blast to the forge by pulling and pushing the handle slowly back and forth. Using dual chambers and two sets of valves, the air is supplied on both the push and the pull stroke, and the blast may be highly intensified or stopped in an instant as needed by the smith.(http://islandblacksmith.ca/2015/06/why-you-need-a-swordsmiths-fuigo-box-bellows/, accessed 18 February 2018)Timber box with handle on the side which pulls out.fuigo bellows, japanese, bellows, fukisashi bellows, oriental box bellows, pump

Drivers were highly skilled enginemen. Taking a train from Beech Forest to down to Gellibrand required the train to be controlled at 10 mph (16 km) without running out of air. When a brake application was made the brakes on the locomotive were applied harder than the train brakes. The brakes locked up and the engine would just slide along. Drivers used a retention valve on the loco, then released the loco brakes so as not to wear out the brake shoes. So the train pulled into Gellibrand ready to pull out again after refilling the loco with water.At Gellibrand, a Down goods train is about to depart the station on 14 December 1955. The train consists of the locomotive G42, a louvre van NO, two NQ wagons and a guard's or brake van NC. B/W.gellibrand; colac; beech forest; railway;

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.

Released in August 2004, the VZ series was a minor facelift of the previous VY series that featured a new V6 engine in different tune guises. The powerplants included 175 and 190 kW (235 and 255 hp), 3.6-litre Alloytec V6 engines in place of the older 3.8-litre Ecotec V6. Other changes to the V6 was the loss of the supercharger that was included in the S models The VZ Commodore was available in several model variations, most of which carried over from the VY range, with the exception of the newly introduced SV6, a specification level that replaced the S range. All models in the Commodore range (Executive, Acclaim, Berlina, Calais, SV6, SV8 and SS) were available as sedans. The advanced 3.6-litre Alloytec engines were more powerful, responsive and fuel-efficient than the outgoing Ecotec V6. To achieve 190 kW (255 hp), the Alloytec V6 gains variable valve timing on both inlet and exhaust sides as well as a dual stage intake manifold, while the 175 kW (235 hp) version retains variable valve timing on the inlet side only. Sales of the VZ series failed to match those of the preceding VY in light of rising small car sales, higher fuel prices and growing interest in the whole new replacement, the VE series. Selected models bring advanced active safety features that electronically assist the driver to maintain vehicle control in emergency situations.
