Zusammenfassung:	POWER TRANSMISSION A speed controller for a rotary pump and motor hydraulic power transmission comprises a pair of pulse generators, one driven at a reference speed and the other proportionally to motor speed. An algebraic summing circuit connects the two pulse generators to the displacement regulator of the hydraulic pump. Error signals produced by the changes in phase of the pulse generators adjust the pump displacement to maintain the motor speed in step with the reference speed. i.
