Abstract

525,599. Thermionic valves. MULLARD RADIO VALVE CO., Ltd. June 5, 1939, No. 16480. Convention date, June 8, 1938. [Class 39 (i)] In a valve wherein a screen 5 causes the electrons to form into beams rod electrodes 3 are placed inside the screen and the emissive surface 2 of the cathode is limited to a small part of the circumference. The grids 8, 9 and anode 10 are circular or of other form to ensure that the electrons impinge thereon at right angles to the grid surface. The rods have a zero or negative bias and the screen 5 a positive potential.
