Abstract
486,743. Mercury-vapour converters. SIGNUM AKT.-GES. Jan. 7, 1937, No. 4612 /38. Divided out of 486,675 and addition to 486,675. [Class 39 (i)] In a starting arrangement according to the parent Specification, the voltage drop at the starting electrode e is increased by a surrounding shield q. The glass or metal cup q preferably extends towards the cathode further than the electrode e and is integral with a sleeve r. Starting may be effected by a thermal element or by the use of an electromagnet h.
