Abstract
466,124. Valve circuits for wireless reception. RADIOAKT.-GES. D. S. LOEWE. Nov. 21, 1935, No. 32285. Convention date, Nov. 24, 1934. [Class 40 (v)] In a short-wave receiver, particularly a superheterodyne receiver for television, electrodes or other elements which are intended to be at zero radio-frequency potential are connected immediately to earth by a condenser which with the unavoidable inductance of the leads forms a circuit with a natural frequency higher than the operating frequency. The screen 3, Fig. 1, of a mixing-valve V1 is connected to H.T. supply in the usual manner through a resistance 8 with a capacity shunt 6 to earth. On account of the inherent inductance, indicated at 9, of the lead, this does not effectively earth the screen nor prevent it from carrying a radio-frequency voltage relatively to the cathode K. The screen 3 is therefore connected to the cathode by a condenser 17 adjacent to or within the valve, and of capacity of 100-500 mmf. A series resistance 16 is connected in the supply lead close to the connection point 20 of the condenser or the lead is formed of resistance wire. Similar combinations of condenser 21 and resistance 22 are provided in the grid-bias lead to the input grid 2, and in the grid input circuit of a following valve V2. The resistance 16 may be housed within the condenser 17 in the manner indicated in Fig. 2.
