Abstract
426,180. Converting. WESTINGHOUSE ELECTRIC & MANUFACTURING CO., East Pittsburg, Pennsylvania, U.S.A.-(Assignees of Slepian, J. ; 1115, Lancaster Street, Pittsburg, and Ludwig, L. R. ; 738, Princeton Boulevard, Wilkinsburg, both in Pennsylvania, U.S.A.) Nov. 21, 1933, No. 28233/34. Convention date, Nov. 25, 1932. Divided out of 426,360. [Class 38 (ii)] [See also Group XL] A mercury-arc rectifier comprises a cathode 1 spaced by an insulator 2 from an anode which consists of a plate 3 and a water-cooled jacket 4. A tubular auxiliary electrode 35 is provided with a heater 38, a quartz extension 36 dipping into the cathode, and a nozzle 37 which directs vapour on to the cathode to form the auxiliary arc. The electrode 35 is connected to the supply transformer 9 through a rectifier 8 and a transformer 20, and the heater is energized by a battery 39.
