The tintype (or ferrotype or Melainotype) was produced on metallic sheet (not, actually, tin) instead of glass. The plate was coated with collodion and sensitized just before use. It was introduced by Adolphe Alexandre Martin in 1853. The most common size was about the same as the carte-de-visite, 5.5cm x 9.0cm, but both larger and smaller ferrotypes were made. The smallest were "Little Gem" tintypes, about the size of a postage-stamp, made simultaneously on a single plate in a camera with 12 or 16 lenses. They were often produced by travelling photographers, and were cheaper than Ambrotypes so made photography available to working classes, not just to the more well-to-do. The print would come out laterally reversed (as one sees oneself in a mirror). Being quite rugged, tintypes could be sent by post. Tintypes were eventually superseded by gelatin emulsion dry plates in the 1880s, though street photographers in various parts of the world continued with this process until the 1950s. (Above information abridged from http://www.rleggat.com/photohistory/history/tintype.htm) The firm of Gove and Allen opened in Sydney in 1880 and were responsible for the belated popularizing of the gem tintype in Australia. The firm traded as both The American Gem Studio and The American Studio. Others franchises were opened in Melbourne, Ballarat and Sandhurst (Bendigo). The Sandhurst branch closed in 1882 and Adelaide in 1884. All Gove and Allen studios had ceased trading by 1885. The studio addresses were: 23 King William St, Adelaide; 324 George St, Sydney; 95 Swanston St, Melbourne; Howard Place, Sandhurst; 7 Queen St, Brisbane; The card mounts used in Gove and Allen studios in Australia are identical to those used in America. They were initially made of plain white card with embossing around the oval image opening in the mount while some also had simple geometric and floral printed designs as well. Although Gove and Allen studios produced the majority of gem tintypes in Australia, other studios offered them including: - London, American & Sydney Photo Company, 328 George St, Sydney; - David Edelsten, 55 & 57 Bourke St, Melbourne; - Burman's Portrait Rooms, St. George's Hall, 209 Bourke St, Melbourne; - Bell's Gem Portrait Studio, 57 Bourke St East, Melbourne; - R. H. Kenny, Bridge St, 6 Sturt St Ballarat; - Marinus W. Bent, Sandhurst (Bendigo); - George Fisher, Victoria; - Anson Brothers, Hobart Town.

An induction coil consists of two coils of insulated copper wire wound around a common iron core. One coil, called the primary winding, is made from relatively few (tens or hundreds) turns of coarse wire. The other coil, the secondary winding, typically consists of many (thousands) turns of fine wire. An electric current is passed through the primary, creating a magnetic field. Because of the common core, most of the primary's magnetic field couples with the secondary winding. The primary behaves as an inductor, storing energy in the associated magnetic field. When the primary current is suddenly interrupted, the magnetic field rapidly collapses. This causes a high voltage pulse to be developed across the secondary terminals through electromagnetic induction. Because of the large number of turns in the secondary coil, the secondary voltage pulse is typically many thousands of volts. This voltage is often sufficient to cause an electric spark, to jump across an air gap separating the secondary's output terminals. For this reason, induction coils were called spark coils. The size of induction coils was usually specified by the length of spark it could produce; an '8 inch' (20 cm) induction coil was one that could produce an 8 inch arc. (http://en.wikipedia.org/wiki/Induction_coil)A metal and plastic object on a timber stand. In an induction coil the distance between the plates is often used to measure the voltage of the spark since the air breaks down at 30 000 volts per centimetreballarat college of advanced education, scientific instrument, induction coil, scientific instruments, electricity

The Ballarat School of Mines was established in 1870 through initiatives of the Ballarat Mining Board which felt there was a need for such an institution because of the declining number of mine managers for the goldfields. In c1990 campuses of the Ballarat School of Mines were: Barkly Street (Business and Computer Studies, Hairdressing and Horticulture apprenticeships); Agriculture Training Centre at the Ballarat Common, Ring Road; Davey Street (Carpentry and Joinery); Ararat Campus (Business Studies, Electronics, Welding, short courses); Lake Bolac TAFE Centre (Woolclassing, Post-Primary Service Programs); Ararat Prison (Basic Education and Training Programs) Howitt Street (Bricklaying); Ballarat Airport (Motorcycle Rider Training Facility.13 page soft covered promotional book covering the Ballarat School of Mines.

The weatherboard Ballarat East State School SS 1071 was formerly known as Specimen Hill. According to 'Visions and Realisations' The Eureka gold lead opened in August 1852, running from Little Bendigo, south beneath Yarrowee Creek into Pennyweight flat, where it was joined 100 yards or so from the intersection of main and Eureka Streets by the Canadian Lead. State School 1071 was formerly known as Ballarat Common School No. 71, and was founded by the Free Presbyterian Church on Specimen Hill in Eureka Street, Ballarat on 01 January 1854. On 20 May 1869 the trustees of the Presbyterian School, Specimen Hill, Ballarat, consented to the transfer of the site to the Board of Education. On 01 September 1870, Specimen Hill, Ballarat, was vested in the Board and then became known as SS 1071. On 01 March 1879 the Minister, The Hon. William Collard Smith, and William Dobbie, Inspector of School Buildings, visited Ballarat to report on the buildings with a view to extensions and renovations. The minister issued instructions for the old wooden part of the school to be demolished, and brick additions to be erected, so that the whole premises would accommodate 350 students.

When Ballarat Junior Technical School building was opened in 1921, there was little cleared space for the students to use for sporting activities. The area known as Battery Paddock was used for dodge-ball and football. Gradually the slope area was cleared and planted. In November 1922 a tennis court was opened in the Battery Paddock. It was designed and built by two former students of the Ballarat School of Mines. The old Mount Doran school house was moved to the area as a students' common room. A new tennis court was built in the same vicinity in 1934. This area was on the corner of Grant and Albert Streets. Area is where the Corbould Building and the Automotive Skills Centre of School of Mines Ballarat Grant Street Campus now stand.

The sulphur crested cockatoo (scientific name Cacatua galerita) is a large white parrot with dark grey-black bill, a distinctive sulphur-yellow crest and a yellow wash on the underside of the wings. Sexes are similar, although the female can be separated at close range by its red-brown eye (darker brown in the male). Sulphur-crested Cockatoos are found in a variety of timbered habitats and are common around human settlements. The birds stay in the same area all year round.

Mount Pleasant Primary School 1435 was formerly known as Clayton's Hill, and evolved from a tent school, commenced in 1855 by William McIntosh. When changed from a Wesyleyan day school to a Common School it was given the number 424, received State funding and was conducted by William H. Nicholls. On 01 January 1873 the school became a non-vested school under control of the Education Department until 31 August 1873. The State then leased the school until 31 July 1874, with the current brick school, Mount Pleasant No.1436, opening on 01 August 1874. The Head Teacher of the new school was William H. Nicholls, remained at the school until 1887. His assistants were Thomas Gray, Jane Shaw, Jane Tratham, Catherine J. Berriman, John Blight, Herbert Berchaivaise and Annie Hicks, all who had worked at Mount Pleasant No. 424. William Nicholls and his assistant Gray established after school classes to enable students to gain Exhibitions and Scholarships to matriculate for the University of Melbourne, and courses enabling entry to teaching, pharmacy and civil service. Before the establishment of State Secondary and Technical Educaiton over 100 pupils from Mount Pleasant Primary School has matiriculated and entered the various professions. (Visions and Realisations, Vol. 2, pg 653 and 767) William Henry Williams became the first classifier of teachers for the Victorian Education Department. He died aged 51 while Head Teacher at Yarra Park Primary School on 01 April 1899. Some former students of this school include: J.G. Eagleston (County Court Judge); H.E. Starke (Judge of the High Court of Australia ); Bernard O'Dowd (parliamentary draughtsman and poet); Albert Coates (Surgeon and Medical Officer in Burmese Prisoner of War Camps).

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.
