Abstract

146,610. Eckersley, P. P. April 10, 1919. Wireless telegraphy and telephony; electric oscillations, producing.-In a system in which energy is only radiated when the microphone or equivalent controlling-device is operative, the grid potential of the power valve R is continuously varied by an independent source of high-frequency current such as an oscillating-circuit C<1>, L' connected to an oscillating valve 0, the frequency of which is equal to that of the antenna circuit. A microphone M, when disturbed by speech, acts on a valve amplifier A and transformer T to apply high potentials across a condenser C<2> in the plate circuit of the power valve R.
