Abstract

503,638. Automatic volume control. COLE, Ltd., E. K., and BROOKE, H. A. Nov. 30, 1937, No. 33010. [Class 40 (v)] A switch S1 ganged with a wave-range switch is closed in the short wave position to short circuit resistance R2. The latter is in the cathode circuit of a H.F. amplifier V1 and in the A.V.C. diode circuit D1, so that when short-circuited the amplification of valve VI is increased and the delay voltage on the diode D1 reduced.
