The Forest Fire Danger Index (FFDI) was originally invented by the grandfather of Australian bushfire science, Alan Grant McArthur, during the 1950s and ‘60s. Alan published his landmark paper, “Controlled burning in eucalypt forests” in 1962. Leaflet No. 80, as it was known, proved a turning point for forest and fire managers across Australia. More importantly, Alan was very practical forester and wanted his work to be useful to people in the field, so after several iterations he came up with the now familiar circular slide rule called the Forest Fire Danger Meter (FFDM). The Mk 4 version first appeared in operational use in 1967. This is the Mark 5 from 1992Alan McAthur's scientific legacy with the FFDI meter is unquestionably huge and has served forest firefighters very well over the decades.Control burning meter Series of circular slide rules to calculate Forest Fire Danger Index (FFDI)bushfire, forests commission victoria (fcv)

This item permitted ironing of clothes to be separate and away from heating stoves. It permitted greater flexibility for ironing clothes and permitted more control (consistency) of the temperature of the iron.Historically and significantly this item enforces the relative isolation of the Kiewa Valley and period when and where this domestic item was in use(manufactured circa 1950). A rural setting with mining, beef , milk and tobacco production in the early 1900s. Even though the community was in a rural setting, the standards of dress was the same as in the bigger towns and cities. Social and religious mores and values demanded that the personal appearance be clean and crisp no matter where a person was living or working. Heavy laborious work was considered by some religions as virtuous, therefore the heavy and tiring work of ironing during this period had its rewards.

The first commercial digital hearing aid was created in 1987 by the Nicolet Corporation. The hearing aid contained a body-worn processor that had a hardwire connection with an ear mounted transducer. While the Nicolet Corporation’s hearing aid was not publicly successful and the company shortly folded, it was able to start a competition between companies to create more effective hearing aids. Two years later, in 1989, the behind-the-ear (BTE) digital hearing aid was launched. In addition to the Nicolet Corporation, Bell Laboratories expanded upon the hearing aid business by developing a hybrid digital-analog hearing aid. When the hearing aid was put on in the market, it was instantaneously successful. This development helped bring major changes to the world of the hearing aid. The next major milestone was creating an all-digital hearing aid. The Oticon Company developed the first digital hearing aid in 1995, but it was only distributed to audiological research centers for research on digital technology in the realm of acoustic amplification. The Senso was the first commercially successful, all-digital hearing aid, and was created by Widex in 1996. After the success of the Senso, Oticon began marketing their own hearing aid, the DigiFocus. Presently, the digital hearing aid is now become programmable. By making the hearing aid programmable, it has allowed hearing aids to be capable of regulating sound on their own, without using a separate control. The hearing aid can now adjust itself depending on what environment it is in and often does not even need a physical volume control button. Silver metal case with side clips and hearing aid attached. Has battery compartment for AA batteries. Volume control is the top left hand corner. "C OF A/CALAID/36778" on back of case deaf children australia, hearing aid, calaid
