Filed: 1958-08-11
Abstract: 898,777. Valves. FIFE, I .L. Aug. 11, 1958, No. 25762/58. Class 135. A diaphragm-operated plunger valve comprises a housing 12 having a plunger 44 disposed within a bore 50 and actuated by a diaphragm 22. The plunger 44 is provided with three grooves 92, 94 and 96, the groove 94 having ports 95 communicating with an internal bore 100. The plunger 44 slides within a liner 52 secured in the valve housing 12, the liner 52 having three external grooves 82, 84 and 86. The grooves 82 and 86, Fig. 6, are provided with a plurality of relatively small spaced ports 88 and 90 respectively. A plurality of circumferentially spaced ports 89 are provided in groove 82 below the ports 88. Similarly, a plurality of circumferentially spaced ports 91 are provided in groove 86 above the ports 90. The central groove 84 has a single port 85. The valve housing has three ports 76, 78 and 80 and the liner 52 is secured in the housing such that the group of ports 90 are adjacent the port 80 and the group of ports 88 adjacent the port 76, the port 85 being aligned with the port 78. The diaphragm 22 is subject on its upper surface to loading from an adjustable spring 34. The lower surface of the diaphragm is open to atmospheric pressure through the bore 50, chamber 74, passage 72, chamber 70 and bore 62. To actuate the valve a vacuum is introduced into the compartment 24 above diaphragm 22, causing the diaphragm to be deflected upwards. In the position of the plunger shown in Fig. 3, pressure fluid entering at port 78 passes, via groove 92 of the plunger 44, to the group of ports 90 in the sleeve 52 and from there out through port 80 to actuate a fluid motor. Exhaust fluid returning from the fluid motor enters port 76 and passes through the circumferential ports 89 to the bore 50 below the plunger 44 and thence to exhaust through the pipe 64. When the plunger 44 in the lowermost position port 80 then becomes the exhaust port and port 76 the supply port to the fluid motor. The ports in the liner grooves 82 and 86 are so disposed that whatever position is assumed by the plunger 44, other than the neutral position, the total area open to exhaust from the fluid motor is always greater than the total area through which fluid passes to the fluid motor from the valve in order to eliminate hydraulic knocking. The degree of vacuum in the chamber 24 may be determined by a sensing head or feeler member.

Title: Improvements in fluid flow control valves
IPC: F16K13/00
Filed: 1963-07-02
Abstract: 1,100,112. Valves; pipe joints. S. B. WESTON. 1 Oct., 1964 [2 July, 1963], No. 26118/63. Headings F2G and F2V. A valve adapted to be mounted in a barrel to permit pressurized dispensing of the contents includes a hollow plug c slidable in a casing a, m. When a dispensing head is pushed into the top of the casing part a, the plug is depressed and causes a rubber 0-ring e to roll downwardly relative to part m and upwardly relative to the plug. This permits gas from the dispensing head to enter the barrel via chamber p, grooves u, chamber t and ports k. The barrel contents are forced up a riser tube (not shown) to chamber n and pass to a central passage of the dispensing head via ports f and passage g in the plug. The dispensing head is secured to part a by means of a two-start interrupted thread which engages lugs o on part a. The energy stored in the 0-ring returns the valve to the closed position when the head is removed. In the valve of Fig. 2, rotation of handle 8 about enlarged portion 2 of pipe 1 causes rotation and upward movement of sleeve 6 since balls 4 located in holes 5 of the sleeve engage helical tracks 3 in portion 2. This movement rolls 0-ring 11 up part 12 of the pipe to allow flow to outlet 17 via ports 13. The energy stored in the ring closes the valve.

Abstract: 1,208,820. Controlling braking electrically. SOC. ALASACIENNE DE CONSTRUCTIONS ATOMIQUES DE TELECOMMUNICATIONS ET D'ELECTRONIQUE "ALCATEL". May 31, 1968 [June 2, 1967], No.26368/68. Heading G1N. An arrangement for stopping an aircraft arriving at the end of a runway at a speed higher than that corresponding to the stopping distance comprises a net 3 and two restraining straps 1, 2 which are retarded by brakes 4, 5 in dependence on control signals derived from measurements of the strap speed and the length of strap unwound. As shown in Fig. 5, the slider of a potentiometer 27 having a desired non-linear characteristic is moved in dependence on the length of strap 2 unwound and a tachometer 28 generates a voltage proportional to the speed of the strap. The output of a difference amplifier 30 is fed to servomechanisms 14, 15 to control the brakes. The voltage applied to the potentiometer 27 is set in accordance with the arrival speed of the aircraft. Initially, relays 19, 25 are in their rest positions R and a voltage source 20, the voltage of which corresponds to the highest anticipated arrival speed, is connected through an operational amplifier 22 to the potentiometer 27. When an aircraft arrives at the net and the straps have started to unwind, relay 19 is energized so that a capacitor 23 in the feedback circuit of amplifier 22 is charged from a voltage source 26 whereby the voltage applied to the potentiometer 27 decreases. When the output of a difference amplifier 29 becomes slightly positive, relay 25 is energized thereby disconnecting the source 26 so that the voltage fed to the potentiometer 27 remains constant from then on at a value appropriate to the arrival speed of the aircraft. Each strap may have its own control circuit, the brakes being controlled independently or by the average of the outputs of the control circuits. By comparing the lengths of the straps unwound, action may be taken to correct the direction of travel of the aircraft. A plurality of arrangements may be used having different characteristics.
