Abstract

230,492. Huth Ges. f³r Funkentelegraphie, Dr. E. F. March 8, 1924, [Convention date]. Vacuum tubes. - A thermionic cathode and electrodes producing a secondary emission of electrons are made of a mixture or an alloy of molybdenum and thorium which is capable of emitting electrons without the employment of any heat treatment for rendering it active; or an electrode of molybdenum is mounted in a bulb and heated for a short time before or after being coated with thorium nitrate, no reducing or binding agent being employed. Specification 230,226 is referred to.
