The Forests Commission developed the use of helicopters for aerial ignition from the mid 1960s. Bryant and May at Richmond worked with the Commission to develop a Delayed Action Incendiary Device. DAIDs as the were known, had an overall length of 180 mm, striker end length - 10 mm. Ignition end length - 80 mm, then a layer of high melting point wax (to prevent accidental ignition when rubbing together in transit). Both ends coated with a modified match head compound with safety fuse exposed length between coated match ends. There was a 17-second delay from when the small end was struck to an intense flaming of the large end, which lasted for 40 seconds. DAIDs were dangerous so were stored in a metal box outside the helicopter along with a disposable striker patch attached with a quick release pin to a special half-door. The first test was with a Bell 47G on 4 October 1967 and the first use, anywhere in the world, of DAIDs to backburn a large bushfire was undertaken in north eastern Victoria in February 1968. There was a crash of an FCV helicopter conducting aerial ignition near Wandiligong on 19 April 1978 with the tragic death of two forest officers and their pilot. The crash led to the immediate end of the use of DAIDs and the adoption of the safer Premo ping-pong ball incendiary machine which originally came from Canada but was modified at the Altona workshops. Overall, the development of aerial ignition techniques by the Forests Commission from the mid-1960s resulted in a steady climb in the area burnt each year…. peaking at 477,000 ha in 1980-81 and with an impressive 10-year rolling average of 220,000 ha around the time of 1983 Ash Wednesday Bushfires.Developed in Victoria for aerial ignitionLarge double ended match used for aerial ignition and back burning by dropping from a helicopterbushfire, forests commission victoria (fcv)

This is one of a collection of items associated with Dr Felix Henry Meyer (1858-1937). Meyer was a very prominent early obstetrician and doctor, playing a part in the establishment of the role of the chair of obstetrics at the University of Melbourne in 1929. He was also a foundation member of the Royal Australian College of Surgeons.Metal optometer. Consists of a glass lens, metal scale and a sliding sight test plate. The words 'CONVEX' and 'CONCAVE' are engraved on the side of the scale. Top of the scale is engraved with various measurements. Test plate is engraved with the words 'COUNT THE DOTS' and a series of dots.optometry

suction regulating deviceOf significance to AHNL as similar to equipment used by nursesLarge glass test tube, with rubber stopper with two holes in top. Through one hole is inserted a long hollow glass tube, through the other hole is inserted a plastic y connector. On one arm of y connector is a short length of orange rubber tubbing, to the other end of this tubing is another larger y connection, with another short length of orange rubber tubing, with a metal clamp attached to bottom. The test-tube is attached to a varnished wooden board by two metal brackets. At the base of the test tube is a small wooden shelf for protection. On this backboard is a marked gradient of 60 cms. Two instruction diagrams are attached. Old catalogue numbermedical equipment, surgical drainage, suction regulator, thoracic surgery
