Abstract

392,391. Thermionic valves. TELEFUNKEN GES. FœR DRAHTLOSE TELEGRAPHIE, 12,. Hallesches Ufer, Berlin. Aug. 8, 1932, No. 22224. Convention date, Aug. 7, 1931. [Class 39 (i).] The anode 1 is of platelike material with openings 2 non-uniform as regards magnitude or form, for example, as shown, or as regards closeness of spacing, to obtain the " variable-mu " effect. The valve has one or more grids which may be non- uniform and the cathode may have different emission at different parts. The electrodes are shown as coaxial cylinders but may be non- uniformly spaced.
