A foghorn is a device that uses sound to warn of navigational hazards like rocky coastlines, or boats of the presence of other vessels, in foggy conditions. The term is most often used with marine transport. When visual navigation aids such as lighthouses are obscured, foghorns provide an audible warning of rocky outcrops, shoals, headlands, or other dangers to shipping. An early form of fog signal was to use a bell, gong, explosive signal or firing a cannon to alert shipping. From the early 20th century an improved device called the diaphone was used in place of these other devices, The diaphone horn was based directly on the organ stop of the same name invented by Robert Hope-Jones, creator of the Wurlitzer organ. Hope-Jones' design was based on a piston that was closed only at its bottom end and had slots, perpendicular to its axis, cut through its sides, the slotted piston moved within a similarly slotted cylinder. Outside of the cylinder was a reservoir of high-pressure air. Initially, this air would be admitted behind the piston, pushing it forward. When the slots of the piston aligned with those of the cylinder, air passed into the piston, making a sound and pushing the piston back to its starting position, whence the cycle would be repeated. This method of producing a low audible sound was further developed as a fog signal by John Northey of Toronto and these diaphones were powered by compressed air produced by an electric motor or other mechanical means that admitted extremely powerful low-frequency notes. The example in the Flagstaff collection is an early cased and portable diaphone used on pleasure or sailing craft. By manually turning the crank handle air is produced and fed into valves that direct air across vibrating metal reeds to produce the required sound. in foggy weather, fog horns are used to pinpoint a vessels position and to indicate how the vessel is sailing in foggy conditions. One blast, when sailing on starboard tack and two blasts, when sailing on a port tack and three dots, when with wind is behind the vessel. Since the automation of lighthouses became common in the 1960s and 1970s, most older foghorn marine installations have been removed to avoid the need to run the complex machinery associated with them, and have been replaced with an electrically powered diaphragm or compressed air horns. The example in the collection is significant as it was used in the early 19th century for sailing vessels was important but these portable crank fog horns have also been superseded by modern electric varieties. Therefore the item has a historical connection with sailing and maritime pursuits from our past.English Rotary Norwegian Pattern nautical foghorn within a boxed pine varnished case with exposed corner dovetailing, original leather carrying strap, brass side crank, and original copper trumped horn.

he subject item is a pedal-powered rip saw with a tilting table made in the USA by W.F. & John Barnes Co. of Rockford, Illinois, between 1874 and 1890. The saw's blade moves rapidly in a circular motion and is driven by a pedal that spins a heavy flywheel with a leather belt attached to a gear drive that in turn drives the circular saw blade. The operator holds a wood workpiece on the table and moves it forward so the blade cuts it to the desired width and length. Company History: WF & John Barnes Co. was established in 1869, by making a formal partnership between William F. Barnes and John Barnes in 1872, and then incorporating in 1884. This company was an early manufacturer of pedal-powered equipment. By 1881 they were also making powered machinery such as lathes and pedestal drills. Many companies were making lightweight foot-powered equipment, but Barnes and the Seneca Falls Co. were the only ones to also make professional-grade workshop machines. From the beginning of their existence, they focused on pedal-powered machinery and specialised in making scroll saws. By 1937 the company focus had completely shifted to automotive assembly machinery, and custom-built machinery, machine tools, electrical, hydraulic, and mechanical controls and systems, including nuclear hardware. their production of foot-powered machinery had ceased. In the intervening years, they have got out of manufacturing completely. After a series of ownership changes, their equipment parts and stock were purchased in 1998 by LeBlond Ltd. of Amelia, Ohio. An item that although incomplete gives a snapshot into the manufacture and use of early woodworking machinery before the introduction of electricity or electric motors to power machines.A Treadle powered tilting table saw benchWF & J Barnes, Rockford Ill USA flagstaff hill, warrnambool, shipwrecked-coast, flagstaff-hill, flagstaff-hill-maritime-museum, maritime-museum, shipwreck-coast, flagstaff-hill-maritime-village

This AC generator operated for the State Electricity Commission in the Ballarat North Power Station prior to World War Two. James Oddie of Ballarat has an association with Thomas Parker of Elswell-Parker. In early 1887 Oddie arrived in England seeking information on electrical knowledge and its developments. At this time Henry Sutton was teaching Electricity and Magnetism at the Ballarat School of Mines. Oddie stayed in the United Kingdom for around three years and during that time became a close friend of Thomas Parker and his family. The two first met at the first official running of the Blackpool tram, and Oddie was invited to visit Parker at Wolverhampton. Over the years Thomas Parker kept newspaper cuttings (mainly Australian) relating to James Oddie and his work. The following article is a description of the Wolverhampton works by James Oddie, and was collected by Thomas Parker. After the dinner at Blackpool, Mr. Parker visited me, and cordially invited me to see his extensive works at Wolverhampton, an invitation I was not slow to avail myself of. This was the keynote of the best friendship I made in England. I went shortly afterwards and stayed several days, visiting the works daily, as Mr. Parker gave me the run of the whole works. There I ordered the installation of a 60 light dynamo, with a 28 cell storage battery and paraphernalia, now doing duty at the Observatory. I subsequently visited the works frequently, sometimes for a week at a time, and I regard it as the brightest spot in my English constellation. Mr. Parker started his works in 1880, with one man beside himself. He never had a single day’s instruction in electricity in his life; now he daily instructs between 300 and 400 employees, who worship him as a father. He is said to be now the most practical electrical engineer and mechanist in Europe. During one of my visits I took with me an artist, who is painting for me a portrait, 6 feet by 5 feet, of Mr. Parker, surrounded by dynamos, secondary batteries, measuring instruments etc. Electric tram cars are going to be a big thing in England. Parker’s Company Limited, is now, with three other companies, in the hands of the Electric Construction Company, with Mr. Parker as manager of the lot. The whole of the works will be taken to Wolverhampton. Before I left, a tender for £50,000 was accepted for the construction of new works.AC Generator painted read and black on a stand.

DEFINITION microfarad Posted by: Margaret Rouse WhatIs.com Contributor(s): Kenda, Jack Clements The microfarad (symbolized µF) is a unit of capacitance, equivalent to 0.000001 (10 to the -6th power) farad. The microfarad is a moderate unit of capacitance. In utility alternating-current (AC) and audio-frequency (AF) circuits, capacitors with values on the order of 1 µF or more are common. At radio frequencies (RF), a smaller unit, the picofarad (pF), is often used. This unit is equal to .000000000001 (10^-12) µF. In RF scenarios, capacitances range from about 1 pF to 1,000 pF in tuned circuits, and from about 0.001 µF to 0.1 µF for blocking and bypassing. At audio frequencies (AF), capacitances range from about 0.1 µF to 100 µF. In power-supply filters, capacitances can be as high as 10,000 µF. Capacitor, 1/3 M.F.D.

George Reed was a draftsman living in the City of Moorabbin c 1950 1899, David Misell, invented this "electric device" ( torch / flashlight) powered by "D" batteries laid front-to-back in a paper tube with the light bulb and a rough brass reflector at the end. Misell assigned his invention over to the American Electrical Novelty and Manufacturing Company owned by Conrad Hubert. In 1905, Hubert changed the name again to The American Ever Ready Company, selling torches / flashlights and batteries under the trademark Ever Ready. In 1906 the British Ever Ready Electrical Company was formed for export of batteries; it became independent in 1914. The American Ever Ready Company became part of National Carbon Company in 1914. The trademark was shortened to Eveready. In 1986, Union Carbide sold its Battery Products Division to Ralston Purina Company becoming the Eveready Battery Company, Inc. and in 1992, it bought the British Ever Ready Electrical Company. Prior to March 1, 1980, the company's alkaline battery had been called the Eveready Alkaline Battery (1959–1968), Eveready Alkaline Energizer (1968–1974) and Eveready Alkaline Power Cell (1974–February 29, 1980). On March 1, 1980, it was rebadged under its current name, Energizer. 2019 production plant in Portage, Wisconsin, but the majority of batteries are made in China and there are also numerous production facilities outside the US.

In 1940 doctors started experimenting with curare for use with electric shock therapy. Electric shock therapy regularly caused broken bones, including vertebrae, and all sorts of dislocations. The intensity of convulsions was high and couldn’t be controlled. During the 19th Century curare was unsuccessfully used to treat rabies, tetanus and epilepsy. By 1935, Harold King had isolated tubocurarine, curare’s active ingredient. In 1942, Harold Griffith successfully used standardised curare (Intocostrin) with cyclopropane. Within five years synthesised muscle relaxants were available. Intocostrin, combined with an anaesthetic agent, was a break-through for this treatment.Solid wooden box with three separate sections inside box. First section contains electrical lead for attaching unit to mains power. Second section contains ECT unit and controls. Third sections contains electrical lead ending in plugs for holding in hands.

Greenbat Battery Loco Built by Greenwood & Batley Ltd Builders No. 420363/2 This Greenbat Battery Loco has been loaned to the Museum by the Walhalla Goldfields Railway, who had acquired it in 2013 along with a large quantity of narrow gauge trollies and light rail from Orica’s now closed munitions factory in Melbourne’s western suburbs. The trolley on display was one of two in use from the 1970s. Orica - Deer Park Munitions factory Orica Deer Park in Melbourne’s west has been used since circa 1875 for various forms of manufacturing and storage of chemicals. Although the site is bounded by Ballarat Road, Station Street, Tilburn Road and the Western Ring Road, the current entry point for industrial operations is situated at Gate 6 off Tilburn Road. Operations include: • a specialty chemicals facility producing products for mining services operations • quarry services • other chemical manufacture activities. The Deer Park factory complex is of historical significance as the location of the first plant for the manufacture of high explosives in Australia and has been, for its entire history, the most important, if not only, commercial manufacturer of high explosives in Australia. It commenced operation under the importer Jones Scott and Co, and then the Australian Lithofracteur Company (Krebs Patent), a rival to Nobel's dynamite patent. The factory was producing nitro-glycerine based explosives in Australia only a couple of years after Nobel's Ardeer factory began operating in Scotland. The explosives factories complex is of historical significance for the association with the Australian Lithofracteur Company, Australian Explosives and Chemicals, the Nobel company and later ICIANZ, which grew to become one of the largest explosives, chemical and plastics manufacturers in Australia. It was the pioneer of the industry and retained its dominance through monopolistic practices, taking over most of its competitors in the Australasian region. Substantial parts of the pre-Second World War layout of the site remain which, with a number of significant buildings dating back to the 1920s and '30s, indicate past and present processes of manufacturing, the necessary safety measures required and the integrated nature of the explosives and chemical industry. The narrow gauge tramway, which ran through the explosives section, was a rare survivor of nineteenth century materials-handling methods into the 21st Century. Greenwood & Batley were a large engineering manufacturer with a wide range of products, including armaments, electrical engineering, and printing and milling machinery. They also produced a range of battery-electric railway locomotives under the brand name Greenbat. The works was in Armley, Leeds, UK. Greenbat was the trade name for the railway locomotives built by Greenwood & Batley. The company specialised in electric locomotives, particularly battery-powered types for use in mines and other hazardous environments.
