Abstract
692,156. Exciting dynamo-electric machines; electricity supply systems. REYROLLE & CO., Ltd., A., and BAYLES, J. W. June 26, 1951 [June 26, 1950], No. 15953/50. Classes 35 and 38 (iv). A welding generator A having series and interpole windings C, D, has a shunt field winding G connected in series with an adjustable resistance H which is short-circuited to increase the excitation when the welding current ceases. The relay J, which closes when the load current ceases, may be connected directly in the load circuit or in parallel with one or more of the series field windings of the machine. Specifications 534,016, 685,714 and 692,155 are referred to.
