Title: Improvements in and relating to plants for delivering measured volumes of liquids
IPC: B67D7/16
Filed: 1927-12-10
Abstract: 311,431. Higgins. H. R. Dec 10, 1927. Direct air-pressure apparatus, non-automatic.- Various grades of lubricating oils &c. stored in drums e are raised by a piston pump f operated by treadle which causes a suction on the branch pipes o of each drum and so raises oil to each of the measured volume containers n from which the oil can be drawn off by taps n<2>. On release of the treadle j, the spring g raises the pump piston and so gives air compression on the top of each container n, to assist in drawing off the oil. To prevent oil being sucked into the pipes of the pump, a fine gauze p<3> is fixed in the top pipe entrance to each container which allows air suction and compression but prevents the heavier oil from passing through. The tap n<2> has a non-return valve n<3>. The four drums e are arranged in a chamber d and the four treadles j are on one shaft roller guided to slide on channels b forming the framework. The drawing off vessels can be placed on platform c covered by a canopy q. In a modification, Fig. 3, each container n is connected to common vacuum and pressure chambers through pipe p<2> and valve r. When valve r is open to vacuum pipe r<1> until the container is filled with oil, the oil presses up on the gauze p<3> as before, but the gauze forms the bottom of a piston the rod p<5> of which moves up to trip the spring- pressure lever and so free the valve and allow it to be turned over by hand to the pressure pipe r<2>. When the pressure empties the container the air rushing through valve p' causes a sudden drop of pressure in pipe p<2> so that piston t<1> descends, releasing valve r from catch t so that the valve can be turned to vacuum again. A syphon delivery pipe u may be used within the container, the pipe being adjustable in height to adjust the quantity delivered. In another modification the valves to suction and delivery may be inside the container and be hand operated.

Filed: 1972-07-18
Abstract: 1425015 Valves LUCAS ELECTRICAL CO Ltd 28 June 1973 [18 July 1972] 33517/72 Heading F2V In a valve, a vacuum inlet 13 leading to a chamber 9 is normally connected to an outlet (15) (Fig. 2, not shown), leading from a chamber 10 but upon lifting of a closure member 16 by an actuating rod 25, the inlet 13 and outlet (15) are isolated from one another and a second inlet 14 (from atmosphere) is connected to chamber 10 and so to outlet (15) for a period wherein, as explained below, the fluid pressure from the inlet 14 slowly builds up in space 7 until a diaphragm 8 moves with snap action against a spring 19 to move the closure member 16 back to its original position unless the rod 25 is still held in the operative position. The space 7 and a space 6 below the diaphragm are normally connected via conduits 22 and 23. When the closure member 16 is lifted, a second free-floating closure member 21 moves under pressure from inlet 14 to isolate the two sides of the diaphragm from one another and connect the space 7 to the inlet 14 via a restricted passage 24 so that the pressure in space 7 builds up. The valve is used in a pneumatic control circuit for the movement of headlamps.

Title: Fuel injection pumping apparatus
IPC: F02M/
Filed: 1974-06-27
Abstract: 1475296 Fluid-pressure servomotor systems CAV Ltd 27 June 1974 [13 July 1973]  33561/73 Heading G3P [Also in Division F1] In a fuel injection pump particularly of the rotary distributer type wherein the timing of injection is controlled by a piston 23 urged in the retard direction by springs 27, 30 and in the advance direction by fuel supplied to a passage 38 by a speed dependent feed pump, a fluid-pressure operable stop.member 33, 34 positions the piston 23 to provide the correct timing for starting when the pump is at rest. The stop 33, 34 is urged to the rest position shown by a spring 36, the latter yielding when, on start up, pressure builds up in the passage 38. The timing is rendered speed and load responsive by pressurizing a piston 26 which feedpump pressure derived from a point situated between a restrictor (39) and an adjustable throttle (15) in the feed line to the pumping chamber (7). The throttle (15) controls the quantity of fuel fed to the pumping chamber and thus the pressure upstream thereof varies inversely with respect to the load. Thus at high speed and low load the piston member 26 is urged by the spring 27 and the load dependent pressure against a shoulder and the piston 23 assumes a position in which it compresses the spring 30 so that an enlargement 32 on the piston 23 contacts a spring abutment 31, 28. If the load should increase, the pressure acting on the piston 26 decreases and the pistons 23, 26 move as a unit against the action of the spring 27.

Title: Monitoring and Control Devices for Blower-Assisted Gas and Oil-Fired Burners
IPC: F23N5/18
Filed: 1968-07-16
Abstract: 1,175,787. Burner control. LANDIS & GYR A.G. 16 July, 1968 [20 July, 1967], No. 33909/68. Heading F4T. An air supply monitoring and control device for blower burners fired by gas or oil comprises an air flap control means 20 which opens an air flap to ventilate the burner on starting and at least partially closes the air flap for ignition of the fuel, a mechanism 6 responsive to the pressure of the air fed to the burner, and a programme control motor 23, wherein a contact 8 of the mechanism 6 is connected into a start circuit of the burner and at least one contact actuated by the air flap control means is connected into a circuit of the programme control motor. When A.C. voltage is applied to terminals 1, 25, a switch 7 is closed and a current flows to the winding 12 of a relay A causing contacts 3 and 4 to close which allows current to flow to the winding 15 of a blower motor and a motor 21 of the air flap control means via a cam selector switch 13 which is controlled by the programme control motor and a limit selector switch 18, to open the air flap. As soon as the air flap is open, the limit selector switch 18 changes over to pass current to the programme control motor via a lead 22 and a cam selector switch 14, which is also controlled by the programme control motor, to begin the ventilation period. At the end of this period cam selector switch 13 changes over to a contact 17 and current flows to the motor 21 via a limit selector switch 19 to close the air flap, the programme control motor being inoperative whilst the motor 21 is operating. When the air flap is closed the motor 21 is cut out and the programme control motor is cut in by the switch 19. After a predetermined time the switch 14 changes over so that the programme control motor receives current directly from the contact 4 and not via the air flap control means. These means can then be set to any required position. If no air pressure is registered by the mechanism 6 then a selector switch 5 does not change over to a contact 9 which is connected to an ignition circuit and fuel supply valves of the burner, thus preventing supply and ignition of fuel.
