Abstract
1,020,284. Cathode heaters. STANDARD TELEPHONES & CABLES Ltd. Oct. 26, 1962 [Oct. 31, 1961], No. 40613/62. Heading H5H. A cathode heater has an insulating coating covered by a layer of uranium oxide for good heat radiation. This layer may be formed by dipping a tungsten heater, having a sintered aluminium oxide coating, in a solution of uranium nitrate, which decomposes to uranium oxide when heated.
