Abstract

196,657. Tester, W. Andrews-, and Thompson, S. Jan. 12, 1922. Drawings to Specification. Systems for alternating-current motors only.- In switching-on alternating-current motors, connection to the main is made through one or more choking coils fitted with movable cores for varying the inductance. Reference has been directed by the Comptroller to Specification 11168/04.
