Abstract: 562,508. Wireless receiving circuits. PERCIVAL, W. S. Dec. 21, 1942, No. 18091. [Class 40 (v)] An arrangement for eliminating heterodyne interference in a wireless receiver comprises a pair of circuits 6, 10 and 7, 11 coupled to the intermediate frequency output circuit 1, 2 and tuned to frequencies lying on either side of the intermediate frequency. Circuits 6, 10 and 7, 11 feed respective diodes 4 and 5 having dividsd load resistances 8, 9 connected as shown. Potentiometer 15 is connected so as to take off the desired amplitude modulation together with heterodyne interference, while potentiometer 20 is connected across opposed halves of load resistances 8, 9 and will receive only the frequency modulation products due to the interference. The outputs are fed to the grids of valves 21, 22, the outputs of which are fed (additively or in opposition according to the position of switch 27) to winding 26 of the audio-frequency transformer 3. The phase of the interference depends on which side of the carrier frequency the interfering frequency lies, and switch 27 is set to give the correct phase for balancing out the interference. A filter 18, 19 in the interference line has a characteristic response such that it maintains the amplitude of the interference at the correct level for balancing, notwithstanding changes in the interfering frequency. A suitable phasing network may be inserted in one of the lines feeding to valves 21 or 22.

IPC: H03F1/54
Filed: 1949-07-14
Abstract: 666,019. Valve circuits. PLESSEY CO., Ltd. July 14, 1950 [July 14, 1949], No. 18601/49. Class 40 (vi). In a self-biased R.F. power amplifier, the screen supply is taken through a D.C. amplifier or a valve controlled by a D.C. amplifier, the grid of which is fed from the bias of the P.A. stage so that when the bias falls, the amplifier conducts to reduce the screen grid potential. A negative potential, derived from resistor R, due to grid current in valve V1, causes valve V3 to be cut off. The resulting high anode potential maintains valve V2 conducting and thus normal screen grid potential on valve V1. Upon failure of the R.F. drive, the grid potential of valve V3 rises causing the anode potential and thus the cathode potential of valve V2 to fall. A resistor R4 is arranged in series with resistor R3 to ensure that valve V3 does not conduct until a minimum R.F. drive has been exceeded. Where valve V1 is a directly heated valve following an indirectly-heated valve, protection is afforded during the warming-up period due to valve V2. In a modification, Fig. 2 (not shown), the screen-grid of valve V1 is connected to the anode of valve V3, and valve V3 must have a shorter heating time than valve V1.
