Abstract

454,116. Supplying consuming devices. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London.-(Patent Treuhand- Ges. f³r Elektrische Gl³hlampen; 11, Ehrenbergstrasse, Berlin) July 23, 1935, No. 20920. [Class 38 (iv)] A number of electric discharge tubes operated from high voltage are independently controlled by connecting in series with each tube a thermionic valve 9, 9<I>, 9<II>, 9<III>, 9<IV> cathode heating of which is electrically controlled independently of that of the other valves.
