With the Japanese cities of Hiroshima and Nagasaki destroyed by atomic weapons, the will of the Japanese leadership was tested Emperor Showa of Japan announced his intention to surrender to the Allies unconditionally over public radio on 15 Aug 1945. The date of Japan's formal surrender was 2 Sep 1945, and it took place aboard American battleship Missouri in Tokyo Bay. There were other surrender ceremonies including that on Sept 6 1945. At 0900 hours, sloop HMS Hart picked up Hitoshi Imamura and Jinichi Kusaka at Kabanga Bay, who would sign the surrender documents aboard HMS Glory at 1127 hours which surrendered 139,000 remaining personnel at Rabaul plus all forces in Australian territory in the South Pacific. The surrender of Imperial Japan was announced on August 15 and formally signed on September 2, 1945, bringing the hostilities of World War II to a close. The surrender ceremony at Rabaul, New Britain took place on 6 Sep 1945 aboard the British carrier HMS Glory surrendering 139,000 remaining personnel at Rabaul plus all forces in Australian territory in the South Pacific.

This item was acquired by the Ballarat School of Mines Electrical Engineering department for use in electric power laboratory as a source of D.C., and also for instructional purposes. This central mercury arc element was located in a cabinet with transparent side panels, and equipped with the required electric accessories, to be a self-contained stand-alone unit. Head of the Electrical Engineering Department at the time was John M. Sutherland.Mercury arc rectifier, 3-phase input. Constructed of blown glass, and complicated configuration: the central inverted truncated cone is provided with 3 large diameter "horns' and four smaller ones. Each horn has electrical connection to outside, some have side horns. Approximately half a cup of free mercury inside the glass complex.

An anemometer is intended for determining velocity distribution over an area or in a boundary layer. This item was purchased by Mechanical Engineering upon the request of Dr Len Cubitt, to determine wind speed at various heights above the ground. Investigation related to wind energy harnessing projects, including that undertaken by MARS Industries in Ballarat. The 6-cup anemometer had a marked superiority in tests over the 3-cup anemometer and also had lower starting speeds.Anemometer in a case complete with mounting blocks, but without electric leads for connecting the black finished wood case which also incorporates pulse counters and connections for power supply and for other logging instruments.

DEFINITION microfarad Posted by: Margaret Rouse WhatIs.com Contributor(s): Kenda, Jack Clements The microfarad (symbolized µF) is a unit of capacitance, equivalent to 0.000001 (10 to the -6th power) farad. The microfarad is a moderate unit of capacitance. In utility alternating-current (AC) and audio-frequency (AF) circuits, capacitors with values on the order of 1 µF or more are common. At radio frequencies (RF), a smaller unit, the picofarad (pF), is often used. This unit is equal to .000000000001 (10^-12) µF. In RF scenarios, capacitances range from about 1 pF to 1,000 pF in tuned circuits, and from about 0.001 µF to 0.1 µF for blocking and bypassing. At audio frequencies (AF), capacitances range from about 0.1 µF to 100 µF. In power-supply filters, capacitances can be as high as 10,000 µF. Capacitor, 1/3 M.F.D.
