Abstract
368,190. Thermionic valves. RADIORÍHRENFABRIK GES., 101, Neu Lokstedterstrasse, Hamburg, Germany. July 24, 1931, No. 21170. Convention date, Aug. 21, 1930. Drawings to Specification. [Class 39 (i).] In flat-shaped valves having three contact pins arranged linearly on the cap the anode pin, which may be central or at an end, is made of larger cross section than the two pins connected to the cathode. An external control grid may be used.
