Abstract
588,227. Non-contact-making relays. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., and WALKER, A. H. B. Feb. 7, 1945, No. 3094. [Class 40 (iv)] [Also in Group XXXV] A reactance for controlling alternating currents comprises a core carrying one or more controlled A.C. windings and one or more controlling windings carrying D.C. derived from the controlled current, in which a permanent magnet having a high coercive force is inserted in the magnetic circuit to oppose or otherwise co-operate with the flex of the D.C. windings, thereby forming a standard of reference for the control.
