Abstract

257,896. Krupp Akt.-Ges., F. Sept. 4, 1925, [Convention date]. Drawings to Specification. Controlling consuming devices. - The heating resistance of a furnace is in three sections which, by means of a switch, may be star connected to a three-phase supply or may be connected in -series across two of the supply leads.
