Marked in a very light almost clear finish on one side "Made in Occupied Japan" See item 8534 for another example - a larger size. https://www.gotheborg.com/glossary/occupiedjapan.shtml - accessed 15/4/20201 gives some background: "For the period from the end of World War II in 1945 through April 28, 1952, the United States and its Allies occupied Japan. The Occupation involved approximately 130,000 Americans (both military and civilian) and about 35,000 British Troops based in Japan. SCAP (Supreme Commander for the Allied Powers), led by General MacArthur, wrote a new constitution for Japan. As Japan needed to rebuild their economy after the war, part of the agreement to allow them to export goods out of their country was that they had to mark 50% of all items with "Occupied Japan" or "Made in Occupied Japan." This could be done with a paper label, cloth label (as on scarves, doilies, clothing), engraved, handwritten or stamped. Thus, you may come across things, such as a salt and pepper set, where only one of the pair is marked OJ and the other will just have "Japan" on it. The tags, labels, marks were placed on the items in Japan, before they were exported to other countries. "trams, tramways, overhead, trolley wire, insulation, electrical equipment

A single rollover kerb has just been laid on western side cut into the embankment. At the crest of the hill on right in front of the Ford Laser is a fire hyrdant. This photo was processed at the same time as image EDHS_07261 of roadworks in Sackville Street about 200 m away which has been dated as c.1983 (between Sep 1982 and May 1983). The paling fence on the left has a change of angle just before the crest of the hill then flattens. More recent Google Streetviews show the same fence and shape and in more recent times a new fence but same shape. Google Streetview for Jan 2008 indicates a more recent road widening and new profile kerb and channel. The embankment was further cut away and the footpath that was adjacent to the fence lowered to road level. The fire hydrant that was on the right hand side has been relocated to the left next to the footpath. Significantly more electrical wires are now strung on the telephone poles. In 2017 Bolton Street was again upgraded. The fire hyrdrant was then relocated to another (unknown) location.1983, footpaths and gutters, road construction, road drainage, road sealing, bolton street, eltham, sackville street

Aerial photos were used to make maps of forest types, timber resources, to survey logging areas and regeneration, to mark boundaries of public land and new plantations, to identify new roads and tracks, as well as for fire suppression. Infrared film was sometimes used to monitor insect and disease attack. The images needed to sharp, with high contrast, and in a large format (most were printed in B&W on 9-inch by 9-inch glossy photographic paper) with at least a 60% overlap to enable stereoscopic viewing and with a 20-30% side lap to allow for aircraft drift. Preferably, the photo scale was close to the final map scale avoid to problems when enlarging and to reduce distortion. Something was needed to supplement the very expensive and infrequent large-area photography programs. From the mid-1960s Victorian foresters began experimenting with small format 70mm and 35mm cameras which proved simple, practical, cheap and flexible. It was found that any SLR camera could be used provided it had a good quality lens and fast shutter speed (preferably down to 1/1000 second). Motorised cameras with a large film capacity had obvious advantages and were essential when access to the camera was not possible during flight. It is also essential for the shutter to operate at low temperatures and those lubricated with silicones were recommended. Components of a typical FCV Divisional Office system included – A Hasselblad or Vinten 70 mm format aerial camera with a focal plane shutter which could be electrically operated. Interchangeable lenses to allow for different photo scales and flying heights. Several large film magazines, which were loaded in a darkroom, each with a capacity of 100 feet or approximately 500 frames. A remote control for the camera in single-shot mode or automatic firing at selected intervals of 2 to 50 seconds. It also needed a frame counter. A light aircraft was modified with an internal mounting for the camera to keep it level and steady. Often a hole was cut through the floor for the lens. The aircraft also needed an inbuilt 12 Volt DC battery to operate the motorised camera shutter. The front passenger seat was generally removed to improve access to the camera. An Aldis drift sight was also fitted. This might be likened to an inverted periscope and is used to determine drift, to facilitate accurate navigation along flight lines and to determine the exposure interval for stereoscopic overlap. This item is kept at Traralgon.Hasselblad 500 ELM camera with 70mm lens, film pack, motor drive and battery In 1964 Hasselblad started production of a motorized camera, the 500 EL The EL/M is a modified version of the EL, "M" means modified, "EL" electric. Perhaps the most famous use of the Hasselblad camera was during the Apollo program missions when man first landed on the Moon. Almost all of the still photographs taken during these missions used modified Hasselblad cameras. forests commission victoria (fcv), forest measurement, surveying, mapping

After the 1939 bushfires the Forests Commission placed orders for 130,000 feet (nearly 40 km) of 1½ inch canvas hose in Britain to accompany over 200 new pumps of various types. The Altona workshop became a major centre for fabrication, repair and storage of hose. But lack of standardisation of hose couplings plagued Australian firefighters for decadesUsed to repair canvas hose A rubber patch is placed over the hole in the hose and clamped. It is then heated electrically to melt the rubber patch Canvas hose needs to be washed, dried, rolled and stored properly after it has been used otherwise it will rot. Unrolled hose is notorious for becoming tangled.forests commission victoria (fcv), bushfire, fire pump, fire tanker

Early form of home heating and because of the copper dish was considered one of the better models|Manufacturing History Museum Victoria|Commentary: Australian manufacturing history Philip Wollen|Many years ago, when I was an ambition young man, I took over a company called Hecla.|This business was formed in 1872, long before Federation was even contemplated. The company established a rich tradition in the Australian manufacturing industry. The prodigious product range included kettles, mixers, toasters, hairdryers, urns, pie warmers, bain maries, and electric blankets for the domestic and commercial market. During the war it even manufactured parts for aircraft. It was one of Melbourne's largest employers.|Hecla was one of the pioneers in TV advertising, led by icons like Bert Newton, Bobby Limb, Evie Hayes and Graham Kennedy who ad Jibbed his way through irreverent and unscripted naughtiness about Hecla electric blankets and foot warmers. The slogan was 'By Hecla, its good.'. One can imagine the fun Bert and Graham had with their double entendres.|In the 60's Hecla entered into a partnership with General Electric and expanded rapidly. The massive factory, on the corner of Alexandra Parade and Chapel Street overlooking the Yarra River was a Melbourne landmark.|The business was formed by one of the scions of Melbourne industry. Mr Marriott was a metal worker of some repute, building the lights in front of Melbourne's Parliament House, the first steam car, the sideboard at the RACY Club, and the first factory to run on electricity.|By the time I acquired the company it was a shadow of its former self, incapable of competing with cheap Chinese imports. Wandering around the warehouse late one night I discovered a large, boarded up storeroom which appeared not to have been opened in decades.|Over several months I combed through the room, unearthing a treasure trove of products from a bygone era. Dusty files, engineering drawings, wooden prototypes, patent records, and correspondence from distributors on every continent.|I decided to track down an old man, Ray, long retired after 50 years with Hecla. He was not well off financially and welcomed the paid work. It turned out that he had done his apprenticeship with the company and there wasn't much he didn't know about it. He had been personally involved in the manufacture of almost every type of product on the Hecla smorgasbord's of products.|So for over 2 years he methodically assembled a mini museum of Hecla products, painstakingly polishing them and ensuring they were in working order. He attached the original brochure of each product and their respective warranty cards. For him it was ,a labour of love. For me it was a fascinating, if vicarious journey, into Australia's manufacturing past.|My colleagues complained that I was wasting money on his salary, our time and factory space on stuff that should have been dumped years ago. I tried to explain that I was merely a steward of the Hecla tradition, not merely an owner. Besides, the look on Ray's face convinced me that there was another dynamic at work. One I could see, but didn't really understand.|After he Passed away I faced a dilemma. What to do with this 'museum' of Hecla history. Nobody was interested.|So I kept the 'stuff' in private storage, hoping that same day someone would be interested in it. And the years passed.|Finally, I had a brainwave. Perhaps the Melbourne Museum would be interested. It was a long shot but I made the call. I had a nagging suspicion that they would think I was simply trying to get them to relieve me of paying for this huge collection to be taken to the tip.|To my surprise they said they would be willing to take a look, I secretly hoped that they would take the whole collection and not leave me with an incomplete jumble of appliances that I would indeed have to take to the tip.|On the appointed day, four serious looking young people showed up. Armed with digital cameras, note books and poker faces they spent four hours analysing the goods and the supporting materials. I asked them if they had any interest and their response was decidedly non-committal. It depends on the acquisitions committee, I was told. I was disheartened and packed up the exhibits to go back into storage.|Imagine my surprise when months later they telephoned to say that they had researched the history of the company, and yes, they would like to take the whole collection. And a truck with 'handlers' would arrive the following day to pick it up. Two years ago all Hecla's archives left me forever and went to the Museum's warehouse.|Well, to my delight I received a call yesterday inviting me to a private viewing of the exhibition at the Melbourne Museum. These young historians had meticulously assembled an impressive display of Melbourne's industry and technology going back to the 1800's. They thanked me like a significant benefactor when it is I who should have thanked them.|I saw the excitement in the eyes of these young people who had somehow managed to dig out and assemble memories from Australia's past. If this is the standard of care that the curators of the Melbourne Museum show all their exhibits, our history is in safe hands.|Their meticulous work took me back to those years long ago when I saw an old man lovingly assembling and cataloging a lifetime of his work.|It took me back to the day when Australians actually made things. Long before we became a nation of quarrymen. Before we became animal-factory 'farmers'. Of a time when products didn't break down, or dumped and replaced before the warranty expired. When men like Mr Marriott cared deeply about what their hands produced.|It reminded me of the call I received from an elderly lady in Tasmania asking for the electrical element for a Hecla K7 kettle. I searched the archives and called her back. The K7 was produced decades earlier and we no longer carried that spare part. She was quite disheartened and told me her kettle had finally 'given up the ghost' and she couldn't bear to part with it. It was a present from her husband on their wedding day 45 years ago. Her final words were 'they don't make them like that, do they? By Hecla they were good.'|I'm glad I followed my instinct and put Ray back on the payroll all those years ago..|I like to think Mr Marriott would have been pleased.Pedestal radiator.

Bushfire behaviour is influenced by many things including temperature, relative humidity, forest type, fuel quantity and fuel dryness, topography and even slope. Wind has a dominant effect on the Rate of Spread (ROS), and also bushfire size, shape and direction. Fuel arrangement is as important as fuel quantity (tonnes/ha). Fibrous and ribbon bark, together with elevated and near-surface scrub fuels act as ladders which lead flames into the tree canopy. But the availability of fuel to burn depends largely on its moisture content. When it exceeds 20-25% not much will burn, whereas 12-15% is generally ideal for fuel reduction burning, but if the moisture content drops as low as 7-10% virtually everything will ignite, and fire behaviour becomes extreme. During the afternoon of the Ash Wednesday bushfires on 16 February 1983 fuel moisture contents were recorded at Stawell as low as 2.7%. Fine fuels like leaves and bark can rapidly absorb moisture after a shower of rain, or from the air when the Relative Humidity (RH) is high, and the temperature is low. Conversely, they can also dry out very quickly. So even though the overall fuel quantity in the forest doesn’t change, the fine fuel availability can increase rapidly from zero after rain to many tonnes per hectare as the fuel dries out. This can happen over a few hours on hot and windy days. Heavy fuels like logs on the ground take longer to dry out. Since the 1930s foresters, firefighters and researchers have been working to develop quick and reliable techniques for measuring fuel moisture content. One of the most accurate methods is slowly drying a sample of fuel in a conventional oven for 24-48 hours to remove all the moisture and measuring the weight difference, but this takes time and is not practical in the field when rapid measurements are needed. But oven drying is often used as a benchmark to compare other methods. Microwave ovens are faster but can cause uneven drying and even char the fuel. They are also not very practical for use in the field. Some mathematical models rely on weather records such as rainfall, wind speed, evaporation, cloud cover, shading, relative humidity, slope, aspect and season of the year to predict soil and fuel moisture. The Keetch-Byram Drought Index of soil dryness is the most common. But complex fuels with leaves, twigs, grass etc make the predictive models often inadequate for fine fuels. The most common technique in Victorian forests until recently was the trusty Speedy Moisture Meter. Originally developed in England during the 1920s for measuring moisture in wheat and other grains it was adapted for Australian forest fuels in the 1950s (I think). Fuel was first ground using a Spong mincer, often attached to the bullbar of a vehicle, and a small sample placed into the Speedy together with a measure of calcium carbide and then sealed. A chemical reaction created gas pressure which was read on the external dial. There were important techniques with cleaning, mincing and using the chemicals with the Speedy to give reliable readings, but it was quick, inexpensive, robust, portable and practical in the field. It was used routinely before igniting a fuel reduction burn or measuring fuel moisture differentials on slash burns. But in about 1996, Karen Chatto and Kevin Tolhurst from the Department’s Creswick Research Station developed the Wiltronics Fuel Moisture meter which measured electrical resistance. Wiltronics is an Australian owned company operating from Ballarat. The final result was a kit that was portable, accurate and could reliably measure fuel moisture contents between 3% and 200%. Although expensive, it is now widely used by fire agencies around the world which has virtually relegated the Speedy to the back cupboard.Prototype Fuel moisture meterT-H Fine Fuel Meterforests commission victoria (fcv), bushfire, forest measurement
