Abstract

453,463. Television. RADIOAKT.- GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, Berlin. Dec. 5, 1934, No. 19660/35. Convention date, Dec. 6, 1933. Divided out of 451,578. [Classes 40 (iii) and 40 (v)] Synchronizing signals, isolated by a gasfilled hot-cathode valve 9, Fig. 1, are used to control the amplification of the receiver. The signals are applied to the resistance condenser combination 14, 13 and a lead 9 is taken to the grids of the amplifier valves. Alternatively, the signals may first be amplified by a valve 15, Fig. 2. Specification 447,401 is referred to.
