This is a set of five photographs of Multiplex mechanical stereoplotting equipment at the Army Survey Regiment, Fortuna Bendigo. c1950s. Multiplex equipment was imported from the UK in 1951 and introduced in the following year, to accelerate map production output covering CMF training areas at 1:25,000 map scale. Multiplex plotting was a productive advancement replacing the ‘Arundel’ method of graphical plotting planimetric detail that was expensive and slow, especially in timbered mountainous terrain. Air photos were made into small diapositives and mounted on racks in the exact position relative to when the aerial photos were taken. The technicians operated the Multiplex in a darkened room, with one photo projected with a green filter and the other through a red filter to form a 3D view of the overlapping photos. The 3D model projected onto a platen, which was a small platform that was raised up and down. The technician viewed the 3D image with special glasses fitted with red and green lenses. In the centre of the platen was a small pinhole that served as a floating mark, with a vertical pencil located exactly below the pinhole. This tracing table was moved to follow the topographic feature or contour line and draw it on the paper underneath. The technician raising or lowering the platform’s floating mark to match the height of the 3D terrain. It also replaced the slotted template method of mechanical adjustment of strips of aerial photography, however was restricted to each strip rather than between strips in the block. Although the Multiplex was phased out of production in 1968, it was used in the training of photogrammetry and aero-triangulation at the School of Military Survey located at Bonegilla, Victoria until the early 1990s. The history of the Multiplex is covered in more detail with additional historic photographs, in pages 50 to 51 of Valerie Lovejoy’s book 'Mapmakers of Fortuna – A history of the Army Survey Regiment’ ISBN: 0-646-42120-4.This is a set of five photographs of Multiplex mechanical stereoplotting equipment at the Army Survey Regiment, Fortuna, Bendigo. c1950s.

This collection of 10 photos was most likely taken at Lithographic Squadron, Army Survey Regiment, Fortuna, Bendigo in 1988. The main tasks undertaken by technicians in Photo Troop were most likely enlargements, reductions and duplication of map reproduction material, and processing of aerial photography.This is a set of 10 photographs of Photo Troop personnel and equipment from Lithographic Squadron at the Army Survey Regiment, Fortuna, Bendigo, 1988.

"The United Pyrites Company's Works are situated about three quarters of a mile from Spargo Brothers, and are on the northern side of the Marong road, in Pinch-gut Gully. Two processes are followed at these works, viz., the amalgamating process and the treatment by means of chlorine gas. The latter is called the Newbery-Vautin system, and the mode pursued is that laid down by Mr. Cosmo Newbery and Mr Vautin, whose names have been given to the process. Mr. Edwards manages these works. Three reverbatory furnaces are used to roast the pyrites, which is weighed in the truck before being put into the furnaces. At this weighbridge a sample of each lot is kept, and if the yield is not equal to expectation, the works are carefully gone over to see where the fault occurs. Care is taken at the furnace to regulate the heat, otherwise the pyrites might slag instead of roasting evenly right through. An immense revolving furnace (made of boiler iron) was used at these works. It was found to be suitable for treating blanket sand, but was not a success for roasting coarse pyrites. The process of amalgamating by means of Chilian mills is the same in these works as at the Western Works, but the United Works are on a larger scale, and eleven mills are utilised. It is the chlorine gas process which is most interesting here. The gas is made from sulphuric acid, black oxide of manganese, and common salt, and the gas is introduced into huge vats, where it works its way through a filter of pieces of quartz and then through the bed of roasted pyrites lying above. The action of the gas transforms the gold into chloride of gold. This is easily dissolved in water, and in that form is drawn off into huge delf jars, where the use of sulphate of iron precipitates the gold to the bottom. A small battery—eight head of stamps in two boxes—is in use here to crush small consignments of stone sent for trial. Test crushings come from all the Australasian colonies, and even from India. The jars used are manufactured at Epsom, and some of the salt used is also of home manufacture, from the Salt Lakes on the Northern plains. Mr. Edwards took us over a new building in course of erection, and in which the chlorine gas is to be generated in the midst of the pyrites— a still further advancement in the new process. There is some very good machinery in this new building, and the tailings from the ordinary pyrites works will also be treated by this chlorine gas system, which has been found to work well at Mount Morgan, in Queensland. The purest of gold is obtained by this process, the gold passing in solution into a charcoal filter, from which it emerges in the shape of metallic gold. We saw some nice cakes of retorted gold at the works. One of 26oz. was from some New Zealand pyrites (2½ tons), and assayed over 23 carats. There were also cakes of Avoca gold, of silver, and of the tremulous amalgam."
