Abstract

456,208. Valve circuits. RADIOAKTGES. D. S. LOEWE, 10, Wiesenweg, Steglitz, Berlin. May 8, 1935, No. 26637/36. Convention date, May 9, 1934. Divided application. Addition to 423,427. [Class 40 (v)] The deflecting-plates 16, 17 of a highly evacuated cathode-ray tube for television are fed in push - pull from an amplifying circuit using a double valve 20. The input 22 of one electrode system is controlled by the output 25 of the other electrode system.
