Abstract: 909,710. Fluid-pressure servomotor control systems; valves. RECHERCHES ETUDES PRODUCTION. March 25, 1959 [March 25, 1958; March 18, 1959], No. 1042/59. Class 135. A control valve for an hydraulic servomotor comprises an electromagnetic motor with a magnetic circuit polarized by two permanent magnets and controlled by two electrical control coils acting upon a plate of magnetic material wherein the plate moves a valve closure member over two nozzles, the valve closure member being mounted on two elastically deformable suspension plates, each nozzle being adjustable in position with respect to the valve closure member during assembly of the control valve. As shown diagrammatically in Fig. 12 the valve comprises an inlet port 23, an exhaust port 23a and a working port 21 leading to the cylinder of a spring-loaded piston. The nozzles 17, 18 enter a pressure chamber and are connected respectively to the ports 23, 23a. Between the nozzles is a closure member 35, 36 carried by two resilient arms so as to be movable to open one nozzle while closing the other connecting the working port 21 to supply or exhaust. In practice the closure member comprises two L- shaped bars 35, 36, Fig. 14, extending across a cylindrical member 30 mounted on a magnetic plate member 9, Fig. 9, supported in the gap of a magnetic circuit by two spring arms 6 and 7 fixed to a bracket 8. The inside of the cylinder 30 constitutes the pressure chamber. The member 9 is located by two adjustable springs 13, 14 and is moved by excitation of coils 2, 2a. Where the servo-piston is double acting and a four-way control valve is required two of the above described three-way valves are coupled as shown diagrammatically in Fig. 7. The assembly comprises an inlet port 21, an exhaust port 22, two working ports 23, 23a, two pairs of nozzles 17, 18 and 17a, 18a and closure members 5, 5a. In practice the closure members 5, 5a are not mechanically coupled together but operate simultaneously, each being carried by a corresponding member 9, 9a, Fig. 2, disposed in gaps of a magnetic circuit comprising coils 2, 2a and four permanent magnets 3, 3a, 4, 4a. Each of the pressure chambers in which a closure member 5 or 5a is located is bounded by a diaphragm 15 or 15a which prevents the operating fluid from circulating near the magnetic parts. The members 5, 5a and the nozzles 17, 18 and 17a, 18a are constructed as shown in Fig. 5.

Title: Improvements in fuel flow proportioners
Inventor: MCCOURTY WILLIAM DONALD
IPC: G05D11/13
Filed: 1957-04-01
Abstract: 831,284. Automatic flow-control systems. HOBSON Ltd., H. M. June 10, 1958 [April 1, 1957], No. 10556/57. Class 38 (4). In a fuel supply system, the rate of flow of fuel from each of a plurality of slave tanks to a common manifold is maintained at a predetermined ratio with respect to the rate of flow of fuel from a master tank by a fuel flow proportioner. In one embodiment for each fuel line 2 a rotating impeller transmitter 3 of the kind described in Specification 752,496 generates an alternating signal which is fed to a pre-amplifier 4 of the kind described in Specification 791,655. The resultant variable-frequency constant amplitude signal is differentiated by a shaper 5 and triggers a rate-of-flow circuit 6 comprising a mono-stable flip-flop. A negative D.C. rate signal derived from the anode of the normally non-conducting valve of the flip-flop has a pulse width determined by the natural recovery time of the circuit, and is adjusted so that the average anode current of the valve has a predetermined value at a maximum rate of flow from the tank. A positive D.C. rate signal is derived from the anode of the normally conducting valve. The negative D.C. rate signal of a slave channel is compared with a positive D.C. rate, selected by a switch S1, in an error comparing circuit comprising a servo amplifier 11 responsive to the sum of the signals in resistors 8, 9 by actuating a polarized relay 16 controlling the rotation of an A.C. motor 18 driving a flow restrictor valve 19 so as to maintain the fuel flow ratio at the predetermined value. The negative D.C. rate derived from a master tank channel 1 is fed to an automatic reference change-over, which on failure of the master channel changes over the switch S1 to a positive D.C. rate from a slave channel 101 and through a switch S2 applies a positive bias to the servo amplifier of slave channel 101 so as to position the flow restrictor valve for maximum flow. In a modification a diode amplitude limiter is connected between the preamplifier 4 and the shaper 5. The positive and negative D.C. rates of a slave channel are compared with those of the master channel in an error comparing network 30 and the resultant signal is fed to a servo amplifier 11 comprising a push-pull amplifier feeding the control windings of a magnetic amplifier determining the rotation of a two-phase motor positioning the flow restrictor valve 19. On failure of the master channel 1, a fail-safe circuit 48 applies a bias to the slave channels 101-103 to fully open flow restrictors 19. The fuel flow from the master tank is controlled by a restrictor valve actuated by a pressure capsule affected by the pressure difference between atmospheric pressure and the pressure in the manifold.

Abstract: 811,409. Fluid-pressure brakes. COMPAGNIE DES FREINS ET SIGNAUX WESTING- HOUSE. April 3, 1957 [April 3, 1956], No. 10870/57. Class 103 (1). A relay valve for use in fluid pressure railway brake systems between a distributer valve D of known type and the water cylinder CF for varying the pressure in the latter in dependence on a vehicle's load or speed, comprises a hollow valve stem 15 subject at all times to movement by a diaphragm 9 having distributer valve pressure below it in space 10 and brake cylinder pressure above in space 19. A second diaphragm 3 at the top of the relay valve has, above it, either atmospheric or control valve pressure depending upon the position of a cock R which may be moved in accordance with the weight on the vehicle by connection to an unsprung part. If control valve pressure is above the diaphragm 3, this is forced downwardly and engages thrust rod 4 to oppose the effect of the lower diaphragm so that the total effect of the distributer valve pressure on the movement of valve spindle 15 is substantially reduced. A similar embodiment in which there is a speed-sensitive control of the cock or valve R is also described. Specification 618,543 is referred to.

Filed: 1968-03-07
Abstract: 1,219,013. Automatic temperature control. KLOCKNER-WERKE A.G. March 7, 1968 [March 8, 1967], No.11266/68. Heading G3R. Temperature detectors, insensitive to ambient temperature changes and responsive to the temperature of travelling rolled material at the entry and exit of a cooling zone are maintained in linear regions of their characteristics to control the rate of cooling and thus maintain a desired exit temperature. As shown, photo-electric cells 1 and 2, responsive to the temperature of rolled wire 8 at the entry and exit of a cooling zone, produce signals which are caused to have a linear relationship with temperature by a servo-operated potentiometer 3 which adjusts the range of operation of the photocells. These signals operate through a controller 4, thyristor unit 6, and a step by step motor 7, to adjust a valve in the coolant supply so that the wire temperature at the cooling zone exit is maintained at a desired value selected by a unit 5 the range of operation of which is also adjusted by servo unit 3. The supply of coolant may be maintained at its previous value in the intervals between runs to prevent large changes. To make the temperature measurement independent of wire diameter, guide ducts may transmit radiation from the wire to the photo-cells which may be of the silicon type. The photo-cells may be made independent of ambient temperature changes by reducing their temperature to a low value by Peltier elements which are cooled by compressed air.
