Patent GB-610712-A (GB)
Title: Improvements in or relating to error signal control systems
IPC: G05D3/14
Filed: 1945-04-16
Abstract: 610,712. Electric follow-up systems. SPERRY GYROSCOPE CO., Inc. April 16, 1945, No. 9521. Convention date, April 15, 1944. [Class 40 (i)] In a servo-control system of the type incorporating fine and coarse Selsyn transmitters and receivers, the output voltages of the latter are respectively applied to the control grids of triodes 15, 16 which are so interconnected with one another that for a minor-range of positional disagreement between the input member 1 and the controlled member driven by the servomotor M the output voltage of the fine receiver only is operative in controlling the motor M and for a major range the output voltage of the coarse receiver is so operative. The triodes 15, 16 are included in a signal control circuit enclosed by the dot-dash line as shown. In this circuit the arrangement is that at zero error, the voltage between points A and C is such that valve 15 conducts and that between A and B such that valve 16 is cut-off. Up to, for example 2 degrees of zero, the amount of voltage between A and B due to valve 15 conducting overrides the coarse signal voltage therefore within this range valve 16 remains cut-off and valve 15 amplifies the fine error voltage so that an output voltage is applied by transformer 18 to the servo-amplifier circuit. As the displacement goes beyond 2 degrees, the coarse signal voltage increases to remove the bias on valve 16. This action causes an additional current to flow through resistance 21 which increases the voltage drop between A and B until finally the coarse signal voltage has increased to such an extent that A-the cathode potential-is positive to the anode of valve 15 rendering the latter non-conductive. In the transition from the fine to the coarse range of control the two signal voltages are additive in controlling the motor M, Figs. 3 and 4 (not shown). The ratio of the high to the low speed Selsyn is an even number 36-1, therefore a phase-shifting circuit 24 is included to control the grid potential of valve 16 to prevent synchronization of the two Selsyns at any point other than zero error. In a modified form of signal control circuit, Fig. 2 (not shown), the arrangement is that when the valve 16 conducts the bias on the tube 15 becomes more negative and the plate voltage less positive The servo-amplifier circuit is of the type employing two thyratons as the control over the motor M. The Selsyn receivers 9, 12 are driven by the motor M through a system of bevel gears and connecting shafts.

Abstract: 729,753. Linkwork. METROPOLITANVICKERS ELECTRICAL CO., Ltd. April 16, 1953 [April 17, 1952], No. 9715/52. Class 80 (3). [Also in Groups XXVI and XXIX] A turbine having two or more inlet valves actuated by a longitudinally-movable operating member connected to the valves by linkage including a floating lever has surfaces provided on the operating member to prevent actuation of the valves other than the first until the surfaces are moved away from the paths of movement of respective points in the linkage system when the operating member has been moved to a position at which the preceding valve or valves are fully actuated. The inlet valves VS<SP>1</SP>, VS<SP>2</SP> and VS<SP>3</SP> of a steam turbine are actuated through linkwork D, G and J by a longitudinally-movable operating member C. The member C is moved by a hand wheel A through bevel gearing B and a threaded extension Cl. Movement of the member C to the right will rotate the bell-crank lever clockwise and lift the lever G and valve. VS<SP>1</SP> will com-. mence to lift. In the event of excessive friction in the guides of valve VS<SP>1</SP> there will be a tendency for the other end K of the lever G to lift and raise the lever J to -the ends M and N of which are attached the valves VS<SP>2</SP> and VS<SP>3</SP>. This is prevented by the surfaces P and Q on the lever C. When the lever C is moved farther to the right and the valve VS<SP>1</SP> is opened fully, the surface P is moved clear of the righthand end of lever J. The lever J then moves about the pivot N and opens the.. valve VS<SP>2</SP>, the lifting of the vavlve VS<SP>3</SP> being still obstructed by the-surface Q.., When the lever C is moved still further to .the right the valve VS<SP>2</SP> is opened, fully. When this happens the surface Q is moved clear of end N of the lever J and valve VS3 will commence to open. When the lever C is moved to the left .the valves will close in the reverse order. Due to the spring S, the surfaces P and Q will only come into action when there is excessive friction in the valve guides. The spring S also ensures that the valves VS<SP>2</SP> and VS<SP>3</SP> are held on their seats when the valve VS<SP>1</SP> is open or partly open. The surfaces P and Q may'be shaped to cooperate with rollers on the ends of the lever J so that as the lever C' is moved to the left the valves VS<SP>2</SP> and VS<SP>3</SP> are positively closed. The invention may be applied to an arrangement having only two valves by omitting the lever J. By the addition of extra floatirig levers and surfaces, the invention may be applied to any number of valves.
