Patent GB-1034407-A (GB)
Title: Improvements in or relating to pneumatic valves of the spool and sleeve type
IPC: F16K31/42
Filed: 1964-07-02
Abstract: 1,034,407. Valves. W. CARLS. July 2, 1964 [July 18, 1963], No. 27439/64. Heading F2V. A spool valve 38 for controlling the connection of cylinder ports 30, 32 with a pressure port 24 and exhaust ports 26, 28 is moved to the left against a loading spring 60 by pressure admitted through a passage 90 under the control of a pilot valve 86. With the pilot valve in the position shown the passage 90 is vented to atmosphere through a passage 108 but when the pilot valve is depressed by a solenoid 96 or push button 98 the passage 90 is connected with a passage 80 opening to an arcuate groove 74 in the face of the pilot valve housing which mates with the end face of the housing 22 of the main valve. This arcuate recess allows fluid under pressure from the port 24 to be communicated through passages 42, 44 to the passage 80 in any of four angular positions about the axis of the main valve in which the pilot valve housing may be mounted by means of four bolts (not shown). The passage 80 may be isolated from the passage 44 by a plug 106 and an atmospheric connection made through a passage 87, in which case a pressure connection is made to the passage 108 so that the action of the pilot valve on the main valve is reversed. Alternatively, an independent pressure supply may be connected at 78 to a passage 76 which communicates with the arcuate groove 74. In a modification the pilot valve and solenoid are coaxial with the main valve which has sprung ball detents to locate it in its two positions and is loaded by fluid pressure instead of the spring 60. A pilot valve may be situated at each end of the main valve. The pilot valves may be removed and replaced by solenoids to provide direct electrical actuation of the valve.

Title: Improvements in and connected with liquid fuel burners
IPC: F23D11/44
Filed: 1958-08-28
Abstract: 858,875. Vapour burners. WYKES, F. May 8, 1959 [Aug. 28, 1958;Nov. 7, 1958], Nos. 27672/58 and 35877/58. Class 75(1). A liquid fuel burner comprises a fuel vaporizer 9 heated by an electric resistance 11, a pump 5 delivering fuel to the vaporizer, a jet 23 for discharging the fuel vapour as a high velocity jet into a mixing chamber 10 and means for controlling the flow of fuel in dependence on the temperature of the fuel vapour. The fuel flow is controlled by an electromagnetic stop valve 8 which is energised by a thermal switch 14 responsive to the wall temperature of the vaporizer. The pump 5 is energised by a rectifier simultaneously with the electromagnetic valve 8. The electric resistance 11 is prevented from becoming overheated by a further thermal switch 12 also responsive to the wall temperature of the vaporizer. When the mains switch 13 is closed the resistance 11 is energised and eventually the thermal switch 14 closes. A push botton 16 is now manually depressed to actuate a relay 15 which closes a first pair of contacts to energise the electromagnetic valve 8 and the fuel pump 5, and a second pair of contacts to form a holding circuit so that the press button 16 can be released. The fuel supply is also controlled by an electromagnetic valve 7 which is energised by a thermal switch 18 responsive to the temperature of water being heated by the burner and allows either full flow or low flow of the fuel. The valve 7 may alternatively be controlled by a room thermostat. In a modified arrangement the push button 16 is dispensed with and the thermal switch 14 is connected directly to the coil of the relay 15. A thermal switch responsive to the temperature of the water being heated energises an igniter for ingiting the burner. The vaporizer, Fig. 2, comprises a cylindrical casing 18a and a tubular metallic core 19 containing the electric heater 11 and having an external square screw thread contacting the inside of the casing 18a, thus forming a helical path for the fuel vapour from the inlet 9a to the discharge nozzle 23. The valves 7, 8 comprise a cone held on a seating by a spring and opened by a solenoid but the cone of the valve 7 has one or more fine grooves which allow a low flow of fuel when the valve is closed. The fuel flow is also controlled manually by a valve 6 comprising a cylindrical valve stem having a triangular flat and adapted to be moved by screwing into a cylindrical fuel passage. The burner may heat radiant elements in a space heater. Specifications 848,203 and 858,876 are referred to.

Abstract: 874,197. Valves for ventilators. BARBERCOLMAN CO. Aug. 14, 1959 [Dec. 22, 1958], No. 27875/59. Class 137 [Also in Group XXIX] A valve regulator for automatically maintaining a constant delivery rate of air through a duct irrespective of variations in the pressure differential inducing the flow, comprises a box-like frame 11, Fig. 1, insertable through a hole in the bottom of the duct and then secured in the duct by screws 18. The frame comprises a partition 12 at its downstream end having an imperforate upper part and a perforate lower part 13 which co-operates with a flexible imperforate curtain 32 extending across the duct and wound upon a roller 38 supported on trunnions 39 in side frame members 33, 34, Fig. 2. A torsion spring 40 anchored at one end to a member 42 fast on the trunnion and at its other end to a cap member 44 secured to the frame winds the curtain on to the roller in opposition to the difference in pressure of air trapped in a pocket 36 between the curtain and the partition 12 and the pressure of air flowing beneath the curtain to maintain a substantially constant volume delivery rate of air. Stops limit the amount the curtain unwinds so that the perforate portion of the partition is never completely covered and a leaf-spring 51 frictionally engages a trunnion to prevent curtain "flutter". Instead of the spring 40 a coil spring 71, Fig. 7, may be fitted. Alternatively the lower part of the partition may be imperforate and the curtain arranged to control an upper perforate part. Sound-proofing material 19 is fitted between the duct and the frame.
