Abstract

425,593. Thermionic valves. RADIOAKT.-GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, and KAPTEYN, P., 5, Schwalbacherstrasse, Friedenau, both in Berlin. June 12, 1933, No. 16701. Void [Abridged as open to inspection under Sect. 91 of the Acts, Dec. 14, 1933]. [Class 39 (i)] In a screened-grid valve adapted more particularly for resistance - coupled receivers the screening- grid 6 disposed between the control grid 5 and anode 7 is connected electrically to the cathode by a conductor 8. The cathode is of the indirectly heated type with a filament 2 connected to supply leads 3, 4.
