Abstract

396,527. Thermionic valves. ERBER, B. and SCHWITZER, A., (trading as GANZ & CO., G.), 45, Van der N³llgasse, Vienna. June 4, 1932, No. 15844. Convention date, July 11, 1931. Addition to 371,419. [Class 39 (i).] A thermionic cathode according to the parent Specification and with the heater filament located in bores of one or more separately formed insulators is mounted at right angles to the re-entrant foot of a thermionic valve used in the vertical position so that the filament lies horizontally and is adequately supported.
