Abstract
613,555. Receiving circuits. AMALGAMATED WIRELESSS (AUSTRALASIA), Ltd. June 14, 1946, No. 18017. Convention date, June 15, 1945. [Class 40 (iv)] In an arrangement, e.g. for use on aircraft, for applying signals from two separate sources to one receiver and for applying signals from one only of said separate sources to another receiver, the signal to be applied to both receivers is fed to an amplifying valve V1 which drives the parallel connected grids of output valves V2, V3, separately coupled by transformers T1, T2, to telephone head-sets A and B respectively. The other signal is applied to the head-set A at 3, 4, cross-talk arising from feedback of this signal through the network C1, R1 being attenuated by means of a capacitor C2, which may be adjustable, connected between the anodes of V2, V3.
