Abstract

252,408. British Thomson-Houston Co., Ltd., (Assignees of Alexanderson, E. F. W.). May 25, 1925, [Convention date]. Vapour and vacuum or low-pressure apparatus, arrangements of.-Smoothed unidirectional current for feeding motors is obtained from an alternating-current supply by an electron discharge tube 12, which may be a mercury vapour rectifier, fitted with four anodes and four grids subject to a variable potential device such as a manually-operated phase-shifter 42.
