Williamstown Botanic Gardens- Hobsons Bay City Council
Photos - Cannons, 1970
The Armstrong Cannons were originally placed at Fort Gellibrand, located at the southernmost tip of the Williamstown peninsula. The Fort was developed during the 1850s as part of a defensive system for the city and port of Melbourne. The importance of the Fort batteries declined from the 1890s, when they were effectively replaced by new facilities at Queenscliff and Point Nepean, but they were still used for gunnery practice. Local residents, through the Williamstown Town Council, complained to the Acting Minister for Defence that the concussion from the guns damaged windows, walls and foundations of buildings. The Armstrong Cannons were moved from Fort Gellibrand to the Gardens in 1906. A primary source of evidence of the cannons being in the Gardens. The cannons are remembered fondly as play equipment for the local children. Many tales have been told of climbing over them and pretending to be shot out of them A collection of seven black and white photographs documenting the removal of the cannons from the Gardens Photo 1 (a) Black and white landscape image. View is looking through the main gates looking at the front of the truck, which has the name Walter Wright across the front bumper, the crane and canon. The gates and fence are painted a light colour, probably white. Photo 2 (b) Black and white landscape image. Back of loader with cannon on it.

Vision Australia
Equipment - Object, Telesensory Systems, Optacon, 1974
The Optacon OPtical-to-TActile-CONverter is a compact, portable reading aid for the blind. It is about the size of a textbook, and weighs less than 2kg. It works by converting a printed image into a tactile image that a blind person can feel with one finger. After a period of training and practice, a blind person can use the Optacon to read ordinary books, magazines, newspapers, and other printed materials. The Optacon was developed after intensive research at Standford University, California, USA and was trialed by clients of the Royal Victorian Institute for the Blind (now part of Vision Australia) in 1973. It has three main sections: 1 a miniature camera, 2 an electronics section, and 3 a tactile stimulator array. The miniature camera, about the size of a pocket knife, is mounted in a housing that has rollers for easy movement along a line of print. The camera is connected to the electronics section by a lightweight cable. The electronics section and the tactile stimulator array are in the main chassis. The array consists of 144 tiny metal rods arranged in six vertical columns and 24 horizontal rows. Each of the rods can vibrate independently. The tips of these rods protrude through holes in a concave finger plate where the index finger is placed flat in order to read. These three components act together to convert the image of a printed letter or other shape into a pattern of vibrating rods, a tactile image of the letter or shape. The letter shape is tactually perceived as an image that moves from right to left on the finger, showing the left or leading edge of the letter first. Letters are felt sequentially rather than all at once, and the image should be kept moving. The Optacon converts a printed O into a tactile form that resembles a crater with a vibrating rim -- a completed circle. C would have a gap or opening on the right side of the curve. The letter F would be felt, sequentially, as a vertical line with two trailing horizontal lines. Because it can convert any ordinary printed image into a corresponding tactile image, the Optacon is not restricted to any special typestyle or language. The camera has a zoom lens that compensates for differences in the size of type. The standard Optacon lens can accommodate type sizes from 6 point to 20 point. With the optional F4A magnifier lens, type sizes as small as 4 point can be read. Powered by a rechargeable battery, and comes with its own battery charger. The battery is contained within the main chassis, and is not removable by the user. There are four basic controls on the Optacon: the Magnification Adjustment zoom button located on the camera section on the side opposite the rollers; and the On-Off switch, the Stimulator Intensity Adjustment knob, and the Threshold Adjustment knob located on the right side of the front panel. The Circuit Breaker protrudes from the right-hand wall inside the chassis compartment. From left to right when the back panel is facing you, are located: the jack for connecting the battery charger; the Battery Check button; the Normal-Invert switch; and the Input/Output I/O connector for use with the Visual Display, when using the Repeater Cable to connect two Optacons to one another or with other accessories. Designed not be removed from the leather case during normal operation, the On-Off switch is a slide switch located on the right side of the front panel. It slides up and snaps into place in the on position. 1 black with orange front, rectangular device in leather case assistive devices, audio equipment -
Parks Victoria - Cape Nelson Lightstation
Instrument - Morse Code Key Set
The battery powered set, which dates from the second half of the twentieth century, comprises two main components, the electronic keyer with a single lever for tapping, and a transmitter (?), both connected by a keying cable. Morse code was invented in the 1830s by American, Samuel Finely Breese by using electrical signals to quickly transmit information over a long range. In the early 1890s Italian inventor, Guglielmo Marconi improved the technology to the point where it became an essential device used for commercial and government purposes. The first practical applications were demonstrated with maritime messaging, where this simple mode of communication was seen as a timely replacement for the historic practice of signaling by flags, lights and foghorns. Cape Schanck has an earlier Morse code key, which is original to the lightstation (CSLS 0035), and Cape Otway has another early example although its provenance to the lightstation has not been formally verified (COLS 0074). The Morse code set has first level contributory significance for its historical value as an earlier communications device that has since been made redundant by more sophisticated technologies.Morse code key set.

Parks Victoria - Point Hicks Lightstation
Lamp, Aldis
This portable, hand held visual signalling lamp was used for optical communication via Morse code. It comprises the metal encased Aldis lamp with electrical cord and its associated green-painted, hinged wooden carrying case, which has a metal clasp and leather hand grip. Larger versions of these lamps are fixed on ships or pedestals and have shutters on the front that are opened and closed to transmit signals. Smaller hand held versions like the Point Hicks example have a concave mirror that is tilted to focus the light into pulse signals via a trigger. The lamps were pioneered by the British navy in the late nineteenth century and continue to be used to the present day.317 Details on the Point Hicks lamp include a serial number and other information. Another Aldis lamp and case remaining at Cape Nelson Lightstation dates to 1960 and has the initials of the Department of Transport, which at that time incorporated the Commonwealth Lighthouse Service. Wilsons Promontory also has an Aldis lamp and case that dates from around the same year. A lamp formerly at Cape Schanck has disappeared. The Aldis lamp and associated case at Point Hicks has first level contributory significance for its historic values and provenance to the lightstation. PHLS0007.1 Hand held signal light.

Pan, Berdan
A Berdan pan was a grinding pan. The circular pan was set at an angle, and as the pan revolved, a heavy iron ball rotated in the lowest point, grinding sand or mineral to a fine powder. It was frequently used to grind impurities out of amalgam (gold in mercury), and to grind batch-lots of heavy mineral. It is also known as a ball mill. Two strong wooden A frames supporting large iron pivotable bowl with a large iron ball inside the bowl. There are cogs underneath bowl which are connected to rotating belts extending from main battery shaft. The chute attached below the bowl is directed into a circular metal container. The frame is painted green.
