Abstract

459,568. Valve circuits for wireless reception. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and ACKROYD, J. O., c/o General Electric Co., Ltd., Wembley, Middlesex. Dec. 6, 1935, No. 33871. [Class 40 (v)] The anode of the signal diode rectifier 6, 19 of a wireless receiver is positively biassed by the inclusion in its circuit of the resistance 10 carrying current from the H.T. supply, so that its impedance is low for weak signals and the rectified output is inappreciable. This muting action may be removed by the closing of a switch 14 connected across the resistance 10 and the switch may be ganged with the volume control resistance 2 so that it is closed when the sensitivity of the controlled valve 1 is at a maximum.
