Abstract
481,071. Metallic - vapour apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. June 10, 1937, No. 16149. Convention date, June 11, 1936. Drawings to Specification. [Class 39 (i)] Relates to ignition devices for rectifiers &c. with liquid mercury cathodes of the type in which a rod of semi-conducting material dips into the mercury pool, and consists in making the surface of the rod smooth. The surface may be polished, or formed by producing the semi-conductor in the form of a glaze on a smooth body. Alternatively, a rod of insulating material such as glass or quartz, finely polished, may have applied to its surface a thin layer of burnt-in platinum of such thickness that its resistance corresponds to that of a semiconductor.
