Abstract: 586,110. Electric control systems. VICKERS-ARMSTRONGS, Ltd., and WATSON, J. P. April 28, 1939, No. 12805. [Class 40 (i)] In a system in which a primary control member such as a director 1 having unrestricted movement controls an object such as a gun 16, having its movements limited as regards speed and acceleration, the control transmission includes a power amplifier 4, such as that described in Specifications 501,030, 586,106, the output of which is connected to the operating shaft of the controlled object by a coupling 10, which may be a slipping clutch, capable of transmitting torque limited by the limitations of movement of the operating shaft, and any want of correspondence between the control member and controlled object is recorded on a hunting switch 23 which controls a motor 13 to drive the operating shaft until correspondence is achieved. The power amplifier 4 is such that there is in the course of its operation want of correspondence between its input and output shafts 3, 5 and in order that the motor 13 shall not be used to correct this, its circuit is closed at 26 only when such correspondence has been restored by the amplifier. As shown, corrections for movement of the target may be introduced on the control side by shaft 20 and differential gear 19, and the shaft 8 driven by the coupling 10 operates the gun by an electrical transmission system 14, 15, the position of the gun being transmitted to the hunting switch 23 by an electrical transmission 17, 25. The drive at 7 between the amplifier 4 and coupling 10 is irreversible. The speed of the transmitter 14 is limited by the speed of the motor 29 of the amplifier, but excessive acceleration of the amplifier output shaft is limited by the flywheel 9. Electrical transmission may be used between the director and the amplifier and the hunting switch may be located at the gun or operating shaft of transmitter 14 together with a follow-the-pointer indicator, both electrically controlled from the director and mechanically controlled by the gun or operating shaft.
