Abstract

282,123. British Thomson-Houston Co., Ltd., and Parry, R. D. March 23, 1927. Electric governors; maintaining speeds equal. -To maintain constant speed of a machine, e.g. an electric motor 20, a tachometer alternator 30 feeds one winding of a synchroscope 32, the other winding of which is fed by alternating current of constant frequency, e.g. from a tun. ing-fork interrupter 35. Movement of the synchroscope spindle 3 due to variation of speed of the machine switches-in, through a steadying relay 29, an auxiliary motor 24 adapted to vary resistance in the field of the motor 20. When the prime mover is a steam turbine the synchroscope contacts bring into action devices for opening and closing throttle valves.
