Title: Improvements in or relating to apparatus for use in the manufacture of artificial filaments, films or the like
IPC: D01D1/09
Filed: 1927-12-17
Abstract: 314,099. British Celanese, Ltd., and Kinsella, E. Dec. 17, 1927. Fluid-actuated valves.-A device for use in the manufacture of artificial silk, films, &c. for delivering a constant flow of liquid under pressure, comprises a. static measuring-device of the orifice, capillary tube, construction or other type, the communication from the source of liquid under pressure to the static measuring-device being through a valve the motor-member of which is exposed on opposite sides to the pressures on the inlet and delivery sides of the static measuring-device, the arrangement being such that a constant difference as between the pressures is maintained. The static measuring-device may also be provided with means such that the desired constancy is preserved notwithstanding variations in the temperature of the liquid. In the form shown in Fig. 1, the static measuring- device consists of an orifice 18 in a plate 17, and the pressure-balance valve comprises a piston valve member 6 mounted on a piston 5, the latter, by means of appropriate passages, being exposed on opposite sides to the pressures on the inlet and delivery sides of the static measuring- device ; the valve 6 controls by one or more ports 12 the supply of liquid under pressure from a groove 13 communicating with the inlet pipe 1, and the construction is such that should an excess pressure develop on either side of the static measuring-device, the supply of liquid is cut off temporarily. In this form the necessary pressure-difference is obtained by means of a spring 16. In other forms the difference of pressure is obtained by employing a heavy piston 5, Fig. 4, the parts being suitably re-arranged; and the piston is replaced by a diaphragm 28, Fig. 3, and the piston valve 6 by a double conical valve 30, Fig. 3. To ensure constant delivery under varying temperatures a conical member 21, Figs. 1 and 2, mounted on a bimetallic strip 22, is fitted within the orifice 18 of the static measuring-device, the parts being arranged so that the conical member 21 enters more deeply into the orifice as the temperature rises. As an alternative, the control-member 21 may be mounted on an expansible capsule 22, Fig. 4, containing a liquid, and, in this case, the member is connected by means of an extension 21A to a diaphragm 26 so that the pressure on the capsule is balanced by the pressure on the diaphragm, actuation of the member 21 by variations in the liquid pressure being thereby avoided.

Filed: 1957-11-05
Abstract: 832,118. Regulating; spray carburetters; starting. FORD MOTOR CO. Ltd. (Ford Motor Co.). Nov. 5, 1957, No. 34439/57. Classes 7(3), 7(5) and 7(6) [Also in Group XXXV] A pressure-responsive control means 23 for a fuel injection pump is connected by a conduit 29 to the intake pipe 21 downstream of the throttle valve and by conduits 30, 28, to a source of atmospheric pressure, the conduit 28 including a normally closed valve 28 which is opened by a temperature responsive device when the engine is cold to increase the fuel flow. The conduit 30 is connected to conduit 27 by parallel branch conduits 38, 39, a subsidiary conduit 28 connecting the branch 38 to the air intake 21. A normally closed suction operated valve 47 opens branch 39 at idling suction to increase the pressure in pipe 27 and increase the fuel supply. During over-running the suction in pipe 29 is sufficient to close a valve 36, producing a decrease in the pressure in chamber 24 which moves the fuel control member to cut off the fuel. An accelerator pump 51 supplies fuel direct from a float chamber 47 to the intake pipe through passages 48, 50. When the engine is at normal operating temperatures a thermostatically operated valve 52 is raised to return the accelerating fuel through a by-pass 53. Fuel is also supplied through a passage 49 controlled by valve 54 when the engine is cranked at cold starting. The valve 54 is actuated by a solenoid 57 the circuit of which includes solenoid operated switch 61, Fig. 2, operated when the starting switch 58 is operated, and a thermostatically operated switch 62 which is closed when the engine is cold. If the accelerator pedal is fully depressed a switch 64 is closed to cause opening of the valve 54, irrespective of the action of switch 62, to prevent vapour locks in the pipe 49.

IPC: G05D16/06
Filed: 1964-08-25
Abstract: 1,083,505. Valves. MASTER PNEUMATIC Inc. Aug. 25, 1964 [Sept. 12, 1963], No. 34646/64. Heading F2V. A pressure regulator has an air inlet 14 and an air outlet 16 with a valve 54 controlling the passageway therebetween. The carrier 52 of valve 54 is urged by spring 88 to its seat 48 being guided by a plug 98, its upper surface being open to the inlet pressure through ports 86. The plug 98 is laterally slidable in a socket 104 and is sealed by an 0-ring 94 which can roll in a groove 92 and in closed position is urged against the upper side of this groove by the pressure difference to effect sealing. The valve is operated by a control rod 66 which seats on an 0-ring 70 to seal an aperture 62. Pressure in the outlet is communicated by tube 58 to chamber 56 the tube having a rounded end with an orifice placed close to the wall of the passage to form a restriction in the direction of flow and being situated in a narrower section of the outlet. When the pressure is too low, therein, a spring 28 urges diaphragm 40 upwards against the outlet pressure to move rod 66 upwards and open the valve. When the pressure is too high, the pressure in chamber 56 depresses the diaphragm against the spring and opens aperture 62 to release excess air through housing 26 and vent 64 to atmosphere. The fall of rod 66 is limited by spring 84. The tension of spring 28 is adjusted by knob 36 to adjust the outlet pressure permitted before aperture 62 is opened. A pressure gauge 22 is connected.

Title: Improvements in control system
IPC: F02K1/15
Filed: 1964-08-25
Abstract: 1,061,396. Jet propulsion nozzles. GENERAL ELECTRIC CO. Aug. 25, 1964 [Sept. 26, 1963], No. 34738/64. Heading F1J. [Also in Division G3] The exhaust nozzle 11 of a jet engine employing an exhaust reheat system is normally controlled by a first control but in the event of failure, a second control is operated to move the nozzle to a predetermined position and lock the nozzle in this position so that a subsequent failure of the second control will have no effect. The nozzle 11 is operated by an actuator 30, 31 by fluid supplied by a wobble plate pump 21. The pump 21 is controlled either by the pilot or by the turbojet fuel control in known manner. A valve 35 normally connects the lines 23, 24 to lines 28, 29 leading to the actuator. A second supply 40 normally supplies oil through a line 42 to a chamber 43 between lands of a second valve 44. The second supply then flows through port 46, passage 47 and line 48 to drain. In the event of failure of the first supply, the gases passing through the nozzle act to open this nozzle causing loss of thrust. The pilot actuates the lever 55 to move the valve 35 downwards which opens line 29 to the port 46 and closes the connection between the port 46 and passage 47. As the actuator is then moved to close the nozzle 11, a rod 59 rotates a cam 61 to move the second valve 44 upwards to open a port 46a which thus allows relief of the secondary fluid. Actuation of lever 55 also acts through a connection 65 on a locking device 66 which is actuated to lock on a flange of the actuator rod 18 to hold this in a closed position.
