Title: Improvements in or relating to amplifiers using space discharge devices
IPC: H03G11/00
Filed: 1930-04-03
Abstract: 352,030. Valve circuits. STANDARD TELEPHONES & CABLES, Ltd., Columbia House, Aldwych, London.-(Western Electric Co., Inc. ; 195, Broadway, New York, U.S.A.) April 3, 1930, No. 10570. [Class 40 (v).] A circuit for limiting electric signal amplitudes comprises two parallel paths connected in opposition at their output ends, and each comprising a push-pull valve pair; the arrangement being such that only signals above a certain amplitude are transmitted through one of the paths. As shown in the Figure, the output from a telephone modulator M is applied in push-pull to two valve 19, 20, the plate circuits of which are jointly coupled through an amplifier A to a transmitting aerial. In parallel with the valve pair 19, 20 is an auxiliary valve pair 21, 22, the plate circuits of which are reversely connected to the output transformer. For normal values of input, the auxiliary pair 21, 22 are inoperative on account of the heavy negative bias applied to their grids by the reresistances 28, 29 in the HT supply circuit 24, 25; whereas the operative pair are biased to a less extent by the resistance 28 only. When input voltage is excessive, the auxiliary pair come into action and oppose the operative pair, thus limiting the output to a definite maximum value. The two pairs may be opposed to each other in their grid circuits instead of their plate circuits, and bias may be applied by batteries. Regulating resistances 30, 31 are provided in the plate circuits of valves 21, 22. Specification 270,817, [Class 40 (v), Wireless signalling &c.], is referred to.
