Abstract

470,366. Wireless signalling. COLE, Ltd., E. K., and GARTHWAITE, E. May 12, 1936, No. 13393. [Class 40 (v)] A combined transmitter and receiver comprises a valve 1 the anode voltage of which is reduced for reception, the resulting change in tuning of the circuit 2, 4, 11, 12 being compensated for or supplemented if the valve is to be used as a local oscillator by the introduction of a series resonant grid circuit 15, 13 shunted by an extra grid resistance 7.
