Abstract

453,074. Discharge apparatus. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London, and SMEATON, T. F., Shadeholm, Bilton Road, SCOTT, W. J., 16, Oval Road, Hillmorton Paddox, and KNIGHT, H. DE B., 108, Eastlands Road, all in Rugby. July 3, 1935, No. 19288. [Class 39 (i)] An electrode comprises a base of solid metal and one or more layers of the same metal forming the surface are made in a rough crystalline form by oxidizing and then reducing in an atmosphere of hydrogen and water-vapour. A tungsten wire may be thus treated, and may be thoriated or coated with barium or strontium compounds or with nickel, so as to constitute a thermionic cathode. Sheet metal, gauze or stranded wire may be treated similarly.
