Abstract
Abstract A synchro-torquing device having a control transmitter synchro, a control receiver synchro connected to receive a data output signal from the transmitter synchro, and means for supplying a torquing current to the receiver synchro, electrical means being provided to obviate the effect of the torquing current on the data signal output from the receiver, whereby there is provided a control synchro system from which can be obtained currentcontrolled torque outputs from either transmitter or receiver without having to employ a separate torque motor.
