Abstract

341,963. Master control of A.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, and BOURNE, S. N., Birdingbury, Rugby. Oct. 25, 1929, No. 32449. [Class 38 (iii).] Star-delta starters; push-button control.-Star and delta contactors A, B are controlled by two pushbuttons. Depressing button T energizes coil a of contactor A, which at auxiliary contacts x completes the circuit of no-volt relay v causing contacts V to close and maintain the relay circuit and prepare the circuit of coil b of contactor B, so that this coil is energized when button T is released.
