A Fresnel lens is a type of composite compact lens developed by the French physicist Augustin-Jean Fresnel (1788–1827) for use primarily in lighthouses.  Made from high-quality glass Fresnel lenses were used originally in lighthouses and later for many other applications They were later being used for automobile headlamps, brake, parking, and turn signal lenses, and many other applications. Fresnel lenses used in lighthouses were considered state of the art from the late 19th through to the middle of the 20th century. The subject item is a Fresnel replacement lens used in a ships navigation light. For lighthouses, these lenses have now been replaced with much less expensive and more durable aerobeacons, which themselves often contain plastic Fresnel lenses. The lens design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design. A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. The simpler dioptric (purely refractive) form of the lens was first proposed by Count Buffon and independently reinvented by Fresnel. The catadioptric form of the lens, entirely invented by Fresnel, has outer elements that use total internal reflection as well as refraction; it can capture more oblique light from a light source making the light visible from greater distances.The subject item at this time cannot be associated with a historical event, person or place, provenance is unknown, the item is a replacement for a ships navigation light and it is believed to have been produced before 1950.Fresnel glass replacement lens for a navigation side lamp of a ship.

Geelong is famous for its bollards. Created by local artist Jan Mitchell, the colourful bollards spot the foreshore, representing a fascinating and fun chronicle of the city’s past. Few people know that Mitchell planned for a flock of sheep to be part of her public art project. The wool industry is an important part of Geelong’s history, so Mitchell thought what better than a flock of sheep to welcome people to the city. The flock (and a Shepard) were to be placed out on the Melbourne-Geelong highway, near Lara, to welcome travellers to the city. The sheep would then be scattered along the road as a wayfinding signal to bring people to Geelong. When traffic authorities heard the plan for bollard sheep along the road, they squashed the project as a potential distraction for drivers. Another flock was also suggested for the hills of the eastern gardens, overlooking the bay. This was also disapproved; so Mitchell only ever partially completed four sheep bollards. The bollards are remnants of Jan Mitchell’s flock of sheep. The sheep also show the evolution of one of Geelong’s most iconic art installations. From the first sheep showing the raw timber of the old Yarra Street pier, to the sheep without a face, through to the completed sheep, it is possible to trace Mitchell’s process in the preparation of the bollards. The lost bollards form part of the National Wool Museum’s unique collection. The first bollard is the least complete, still in its original timber colour. From the central cylindrical shape, an additional wedge protrudes. This unpainted wedge forms what would have been the face of the sheep, with an ear present on either side that would have been painted white. Presently they are a bare metal. No legs are present on this bollard. The second and third bollard are completed to a similar level. They have a central cylindrical shape with an additional wedge protruding from the front of the timber. This wedge forms what would have been the face of the sheep, with an ear present on either side. The face and ears have been painted white but the finer details such as the eyes have not been added. These bollards bodies have also been painted white and have their legs attached. The legs are thin metal cylinders, approximately 50mm in diameter and 500mm long. The fourth bollard Is complete. It has the same central cylindrical shape with an additional wedge protruding from the front of the timber. This wedge forms the completed face of the sheep, with an ear present on either side that has been painted white. The face also features completed painted eyes. This bollard has its legs attached. The legs are thin metal cylinders, approximately 50mm in diameter and 500mm long. geelong, bollards, geelong's bollards, jan mitchell

In 1975 the Melton Fire Station opened in McKenzie Street. In the 1950s with the introduction two-way HF and later VHF very high frequency radio sets. Melton Rural Fire Brigade was part of the Bacchus Marsh Group. Radio sets where located in the Melton Fire Truck, and in the house of the Barrie family at Ferris Road. This was an ideal location to observe a 360 degree view in all directions when smoke appeared on the horizon. An antenna was erected beside the house. The set OX 7 was located in the kitchen and monitored 24 hours by the family. When an electrical fire occurred at the junction of the electricity to the house there was time to radio the fire station and summons the men working in the paddocks, thus saving the house from possible destruction. With the introduction of UHF – ultra high frequency Vinten Radios the signal was clearer and static and interference lessened and radio traffic became easier to read, and reduced noise levels in the household. In 1974 when the family moved to First Avenue, another antenna and a small building were erected adjacent to the residence and used to house the equipment, maps. Radio traffic consisted of regular schedule times and communication with adjoining groups of brigades such as Bacchus Marsh, Mt Macedon and Little River Groups. Many of the brigade and group base radios were situated in private residences and operated primarily by fire fighters wives who held the position of Communications Officer, either registered as a brigade member or informally.Regional News Gazette article about the construction of a new fire station in Melton and an Express article with brigade members at the opening of the station.emergency services

Lightning is one of the major causes of bushfires, particularly in the remote mountains. This lightning detector system was developed by Dr. Peter Kourtz at Canada’s forest fire research institute. By 1977, some 300 were in use across the country. The small mushroom antenna could detect short-range (20-mile) changes in electrostatic field associated with lightning strikes. It needed to be placed out in the open on a hilltop and away from nearby trees. It simply counted the number of "strikes". The detector doesn't seem to have a direction finding capability or be able to distinguish between cloud-to-cloud or cloud-to-ground lightning. It's not sure how this particular unit found its way to Victoria. The Bureau of Meteorology's (BOM) current lightning detector network uses radio waves emitted by lightning to pinpoint the location of lightning strikes. The network is operated by a private company that sends data to the BOM in real time. Lightning detection systems use sensors like antennas, GPS receivers, and processing systems to detect radio waves, also known as sferics. The systems calculate the lightning's location and speed by measuring how long it takes for the radio signal to reach the different antenna stations. The BOM also has a Thunderstorm Tracker that uses weather radar data to identify areas of potential thunderstorm activity. The tracker updates every six minutes and shows the direction thunderstorms are moving, as well as their expected position in 10, 20, and 30 minutesLightning detector 1970sQ-Techforests commission victoria (fcv), weather, bushfire, bushfire aviation

After the 1939 bushfires, the Forests Commission Victoria invested heavily in a radically new communications network. After suffering some inevitable delays due to the war, radio VL3AA switched into full operation in October 1945 proudly beaming out 200 watts across the State. But by today’s standards, the technology was primitive and the reception poor unless the user was on a high point somewhere. The radio signal was "line-of-sight" and bounced between fire towers and relay transmitters across the mountains back to the District offices. The advent of solid-state electronics in the 1960s replaced the more delicate valve sets which enabled greater use of vehicle mounted radios. The Commission continued to research, develop and build new radios at its many workshops around Victoria. The network was supported by a large team of skilled radio technicians. The more secure and versatile State Mobile Radio (SMR) digital trunk system came into operation in about 1995. Upgraded Tait Radios were purchased in 2014 after recommendations of the 2009 Bushfires Royal Commission. But it was the convergence of separate technologies such as 5G mobile phones, high-capacity and light-weight lithium batteries, Wi-Fi, the ever-expanding internet, cloud data storage, digital cameras, GPS, personal organisers and hundreds of supporting Apps into powerful smartphones and tablets which revolutionised bushfire communications from the mid-2000s.

Upgraded Tait Radios were purchased in 2014 after recommendations of the 2009 Bushfires Royal Commission. But it was the convergence of separate technologies such as 5G mobile phones, high-capacity and light-weight lithium batteries, Wi-Fi, the ever-expanding internet, cloud data storage, digital cameras, GPS, personal organisers and hundreds of supporting Apps into powerful smartphones and tablets which revolutionised bushfire communications from the mid-2000s.

After the 1939 bushfires, the Forests Commission Victoria invested heavily in a radically new communications network. After suffering some inevitable delays due to the war, radio VL3AA switched into full operation in October 1945 proudly beaming out 200 watts across the State. But by today’s standards, the technology was primitive and the reception poor unless the user was on a high point somewhere. The radio signal was "line-of-sight" and bounced between fire towers and relay transmitters across the mountains back to the District offices. The advent of solid-state electronics in the 1960s replaced the more delicate valve sets which enabled greater use of vehicle mounted radios.
