Abstract

1,070,231. Electric selective signalling. CREED & CO. Ltd. March 4, 1966, No. 9537/66. Heading G4H. [Also in Division H4] A keyboard-operated code generator, e.g. for a teleprinter, comprises a plurality of resilient tubes (4, Figure not shown) combinations of which are compressed by projecting parts (3) of a keybar (1) when pressed, the tubes being supplied with a gas under pressure and there being means such as a temperature-sensitive heating element (9) for each tube which responds to the cutting off of the gas to produce a signal.
