Title: Improved alternating current motor control system particularly for position regulating applications
IPC: G05D3/18
Filed: 1967-01-11
Abstract: 1,137,802. Automatic control of speed. WESTINGHOUSE ELECTRIC CORP. Jan. 11, 1967 [Jan. 20, 1966], No. 1535/67. Heading G3R. [Also in Division H2] Pulses of an A. C. supply voltage are supplied to a servomotor 28 at a rate which depends upon the difference between the actual position of a load 14 and a demand position by a system having higher and lower error feedback loops to produce higher and lower motor velocities respectively. As shown, the difference, derived at 32, is used as a variable reference value for comparison with an actual speed signal from tachometer 108, and the result, integrated at 110, controls the pulse rate, but in an alternative arrangement Fig. 2 (not shown) the position error controls the pulse rate directly. The motor is preferably a 3 phase squirrel cage machine; one phase is connected directly to the supply, the other two via pairs of back-to-back thyristors, triggered by 1000 CPS. oscillators via a transistor gate; there are separate thyristors and triggering circuits for each direction of rotation Fig. 9 (not shown). The triggering gates are opened for a time sufficient for the thyristors to conduct preferably for a complete cycle of the supply by pulses which originate in a transistor "staircase" circuit 64; this builds up voltage on a capacitor by one increment for each cycle of the A. C. supply until a transistor conducts to start a pulse, the length of which is predetermined by a delay network; the number of increments necessary, and hence the pulse rate, is determined by the biasing effect of the position error dependent voltage. The position error voltage is also compared with set points in comparators 48, 56 or 50, 58 and by a system of AND and OR gates it is arranged that when the error exceeds a predetermined value the motor is continuously energized to. run at full speed and the controlled pulse rate system is effective only when the error is below this value. In the speed controlled system shown the drive pulses are blocked when the speed is above the instantaneous reference value and shorter pulses, of length determined by circuit 117, of reverse current are applied to brake the motor. When the load reaches the demand position it is held by D. C. applied to the motor or by a mechanical brake.

The working stroke of a machine tool is maintained at a constant speed by discharge regulator 25, except when cylinder 2 has moved to such a position that cam follower 31 rides over cam face 33, which causes valve 26 to open and allow liquid to exhaust freely. At the end of the stroke, lever 18 of reversing valve 15 is knocked over by bracket 29 on the cylinder. The return stroke is effected at high speed, since valve 26 has no resistance to pressure liquid from the pump, and liquid from chamber 4 of the cylinder may exhaust freely. Specification 830,853 is referred to.

Title: Hydraulic Flow Limiting Device
IPC: F15B11/042
Filed: 1968-01-11
Abstract: 1,192,091. Fluid-pressure servomotor systems. BELL AEROSPACE CORP. Jan. 11, 1968 [Jan. 13, 1967], No. 1671/68. Heading G3P. A device to control the rate of fluid-flow from a servovalve Fig. 3 comprises a differential piston 22 slidably mounted in a chamber 20 between an inlet 56 and an outlet 58 and having a restrictor 24 to permit flow therethrough, a continuously variable valve 30 in the path of the fluid-flow, and means 28f responsive to the pressure on the downstream side of the restrictor to determine the opening of the valve as a function of the pressure, whereby fluid-flow greater than normal will cause an increased pressure drop across the restrictor to cause the piston to move downstream tending to maintain the pressure downstream of the restrictor until the piston has reached the end of its travel when the opening of the valve 30 is reduced by the fall in downstream pressure. When the device is used in an automatic flight control system, the delay in operation of the valve 30 caused by the travel of the piston 22 enables the controls to be taken over manually when a malfunction occurs. A stop 72 may be used to adjust the delay. The valve 30 is interposed between the servovalve which is electrically controlled by a torque motor and a double-acting ram controlling the position of an aerodynamic element in the pitch of the blades of a helicopter.

The zinc cups of a battery of the layer type which may be as described in Specification 579,986 are lined with sheets of cardboard &c., which carry the electrolyte where they make contact with the bottoms of the cups and insulate the sides of the cups from adjacent cups, the sides of the linings being rendered impermeable by an insulating substance which is applied by a printing process to a continuous thin cardboard band which is then cut into sheets from which the linings are formed. The insulating substance may be delivered to the printing roller as an ink of bitumen dissolved or softened by a solvent, or of a plasticized or dissolved synthetic plastic material. The band is printed on both sides either by separate rollers or by passing the band twice over the same roller. Teeth on the roller enter holes in the band to ensure accurate registration of the unprinted areas on the two sides of the band. The Figure shows a part of a band of thin card which will absorb and retain the electrolyte in the unprinted areas 3, the edges of the band being provided with holes 2. The blank areas 3 may be produced by forming the surface of the printing roller with corresponding openings. After the band has been printed on one side it is passed through an oven to evaporate the volatile constituents of the ink and to melt the bitumen or plastic which then penetrates into the band. The printing, drying and impregnating processes are then repeated on the other side of the band. The linings for the zinc cups are then cut or punched out as shown at 4. The punching machine may also crimp the corners 5 of the linings which may be inserted in the cups by the machine described in Specification 642,361, or the punch of this machine may be shaped to pleat the corners as the lining is being forced into the cup.
