Abstract

221,029. Hart, H., (Ford Motor Co.). June 19, 1923. Systems for continuous-current motors only.- The power taken by an electric motor 9 driving the runners of glass grinding or polishing apparatus is maintained constant by a relay 5<a> functioning to vary the speed of the motor. The relay is sensitive to potential variations across a resistance 8 in the motor circuit and controls a servo-motor 10, which derives power from a battery 6 and which adjusts a variable resistance in the shunt field of the motor 9.
