Abstract
212,656. British Thomson-Houston. Co., Ltd., and Hastings, H. C. Dec. 15,. 1922. Controllers, actuating; master control systems, electromagnetic. - In controllers comprising motor-operated cam-shaft contactors of which one or more are employed as circuit-breakers, the circuit-breaker contactor, indicated in the diagram as a switch 1, and adapted to be closed through a cam shaft by an auxiliary motor 10. is left mechanically free after the closure and is retained set by a shunt coil 1<b>. The control circuits running from master switches 11, 12 are arranged so that the hold-on coil remains energized in all the normal starting and running stages, but is de-energized so as to open the power circuit, when the master switch 11 is returned to its off position, or when an overload relay 6 or a no-voltage relay 7 responds. Specifi. cation 201,105 is referred to.
