Abstract: 591,128. Electric control systems. BELL, J., and DRYSDALE, C. V. Sept. 5, 1933, No. 24554. [Class 40 (i)] In a. correspondence control system employing resultant field devices the lag which occurs when the controlling member 18 being moved is eliminated by advancing the magnetic field of the transmitter rotor in accordance with its speed so that the transmitted signal corresponds to the rotor being in a position in advance of its actual position. As shown, an additional winding E is provided on the transmitter rotor and is energized through a phase-advancing machine which is mechanically coupled to the transmitter rotor so that it gives an output proportional to the transmitter speed. The stator signals are applied to device I, mechanically coupled to a device J. Any change causes the rotor of I to rotate until the change in the signals from the stator of J have caused the resultant stator field of I to change as much as the rotor field. The rotor K of J is provided with a similar winding to E which may be shorted, or energized in the same manner as E. Device A may be replaced by a variable coupling transformer, the coupling control being coupled to the transmitter through a differential device. Specification 395,764 is referred to.
