Abstract

806,736. Automatic speed control. SQUARE D CO. Oct. 20, 1955 [Nov. 2, 1954], No. 24880/57. Divided out of 806,735. Drawings to Specification, Class 38 (4). The system described is the same as that in Specification 806,735 wherein the speed of a motor in a Ward-Leonard system is controlled through a pair of electronic circuits but the claims are directed to the switching to the input of the control circuit of the generator output when the connection between the generator and the motor is opened.
