An International Transistor Exhibition was filmed at Earls Court London May 20. Exhibits range from one of the world's smallest wireless sets to a thermo-electric generator.
British, Belgian, French German, Italian, Japanese and American stands abound with transistorized equipment of the latest technical standard.
One of the smallest portable wireless sets, hardly as large as three match boxes, is shown by the Tokyo Shibaura Electric Company.
A silicon transistor radio receiver made by a British firm is capable of working at an ambient temperature of 100? C (212? F - boiling point).
An exhibit underlining the most important advantage of transistors over the cumbersome conventional radio valve - their tiny size - is a slender cylindrical container filled with GBP3,000 worth of transistors. Visitors to the exhibition are invited to guess how many of the pea-size gadgets there are in this container, a greatly enlarged transparent plastic model of a standard transistor.
From valves to power and from transistors to the thermo-electric generator shown by Wayne Kerr Laboratories. Developed by a Russian professor of the Leningrad Institute of Semi-Conductors this device converts the heat produced by an oil lamp into electric power to operate a radio set. The two-watt junction type generator is mounted round the chimney of the lamp and can provide an anode voltage of 80-90 volts. It is designed to replace dry batteries and, at the same, to be used as a source of light in the remote parts of Russia.
Concurrent with the exhibition is a Transistor Convention promoted by the Institution of Electrical Engineers during which some 200 special papers on transistor and semi-conductor development, design and world technical trends are expected to be read to 2,000 delegates from all over the world.
