Abstract

531,200. Thermionic valves. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 30, 1939, No. 19076. Convention date, June 30, 1938. [Class 39 (i)'] In a valve the anode 5 has side extensions 9 formed with tapered embossings 12 which enter slots 13 in mica electrode spacers 6. The end 10 of the anode limits its position on the spaces which are perforated to receive the support rods 7 for the assembly and the grid rods and cathode.
