This item was used at the Ballarat School of Mines Physics department until the 1970s-1980s to demonstrate that electrons have a straight line. A sealed conical glass tube, equipped with two electrical connections. One, at the narrow end, terminated inside with a sic shape electrode and faces a cross-shapped aluminium steel target near wide end. Other electrode is side branch, which also provided means of mounting on a polished wood circular stand. A Crookes Tube is an early experimental electrical discharge tube, with partial vacuum, invented by English physicist William Crookes and others around 1869-1875, in which cathode rays, streams of electrons, were discovered. May also be called a Crookes–Hittorf tube or Maltese Cross Tubemaltese cross, crookes tube, physics, electron emission demonstration, cathode rays, vacuum tube, electrons, crookes–hittorf tube, maltese cross tube

The book was published for the use of personnel of the army, navy, marine corps and coast guard. The book was used by Charles Bacon who studied at the University of Nevada in the late 1930s/early 1940s. Bacon worked at Bunker Hill Mines and Kellogg Idaho, before arriving in Australian in 1951. He worked for CN Myers, a company involved with paper converting. CN Myers was a family business (on Charles Bacon's maternal line).Blue soft covered book of 607 pages.

Standard Telephones and Cables Pty Ltd was a telecommunications company that began as part of Western Electric, a telephone manufacturing company set up by Alexander Graham Bell. Following the First World War, Western Electric diversified to include electric generators and wireless receivers, all still imported. In 1925, Western Electric was sold to the International Telephone and Telegraph Company. In Australia, it became known as Standard Telephones and Cables (Australasia) They worked closely the Postmaster Generals department to set up telephone and radio networks throughout Australia. Its first factory was in Chippendale, New South Wales but ut developed to have branches in all stated of Australia. By the end of the Second World War STC was Australia's biggest manufacturer due to its critical role in producing telecommunications equipment, domestic radio receivers, telecom cables, military equipment and electron tubes. The company returned to peacetime manufacture. Rather than reduce staff it used its excess capacity to produce electric irons and other domestic appliances including vacuum cleaners and floor polishers. This model was produced at the beginning of the 1950s. It was once owned by Mr. Stiff from Stiff and Gannon, Wodonga.This item has local and national significance. It was used in a local Wodonga business and is representative of domestic appliances used in the 1950s. It also has national significance as it is an excellent example of good produced by the manufacturing industry in Australia during that period.Model 30 Airzone Vacuum Cleaner and accessories.

Merle Hall Collection: Rosalind Park Creative Village Bendigo Project Pamphlet for Rosalind Park Lookout - two copies. One side of the pamphlet has a layout image of the five sections of the mosaic and the poppet head base. The sections are numbers 1 to 5 Section 1: A stylised representation of the main Bendigo Goldfield based on a geological plan (Publish in 1992). It shows the lines of reef, including the famous Hustlers, Garden Gully and New Chum. Section 2: A typical cross section of the Bendigo Goldfields Section 3: The mine layout shown in this design features part of the Garden Gully line of reef. Section 4: Shown here is the Iron Bark mine on the Sheepshead reef. It has an interesting pattern of drives, stopes and winzes. Section 5: In this section the artist uses gold as her inspiration. The larger mosaic shows quartz veins winding through the earth containing gold in its various forms. The smaller mosaic represents the atomic structure of gold. It shows the the nucleus, the six shells of the atom, their electrons and orbits. The other side of the pamphlet describes the background of the community arts project, the artist, and volunteer workers, also notes mentioning the Bendigo community history. It also lists the donors for funding and business's that supported the project, with special thanks to Eric Wilkinson - Geolpogical advoser, the students and staff from Camp Hill, St Killians and Violet Street primary schools.

A Crookes tube is an early experimental electrical discharge tube, invented by English physicist William Crookes and others around 1869-1875, in which cathode rays, streams of electrons, were discovered. Wilhelm Röntgen discovered X-rays using the Crookes tube in 1895. The term is also used for the first generation, cold cathode X-ray tubes, which evolved from the experimental Crookes tubes and were used until about 1920.(http://en.wikipedia.org/wiki/Crookes_tube)Glass vacuum tube with a metal maltese cross inside.
