Abstract: 1389839 Carburtters; fuel systems CALOR GAS Ltd 22 Sept 1972 [23 Sept 1971] 44420/71 Heading F1B Liquefied petroleum gas control apparatus comprises liquid l.p.g. fuel inlet means 17, Fig. 1, communicating with an engine air inlet duct 1 through a fuel metering aperture 13 which is  movable transversely of the air duct in dependence on air-flow, the fuel flowing continuously through the fuel metering aperture, a control member 20 mounted on the opposite side of the air duct to control the area of the fuel metering aperture in dependence on the position of the latter and heating means 43 for the control member remote from the part co-operating with the fuel metering aperture. Member 20 is movable to control the fuel/air ratio by rotation of lever 32 or by screwing member 26 into or out of part 24. The engagement of member 38 with pad 39 prevents fuel escape when the engine is stopped. Chamber 40 receives hot water from the engine and a throttle 2 may be heated by hot water fed through ducts 43. Alternatively the member 20 is electrically heated. Ice or hydrate deposition may be reduced by coating internal surfaces with P.T.F.E. The fuel supply pressure is maintained constant by a controller 50, Fig. 2, in which fuel from inlet 51 flows to outlet 52 and fuel pressure acting on diaphragm 55 varies the bleed-off via a tapered valve member 56. In a modification inlet manifold pressure is admitted to chamber 62 to control the fuel supply in the engine idling condition. A fuel supply system includes a storage tank 100, Fig. 3, from which fuel is pumped by pump 101 through filter 102 to the pressure controller 103 and thence to carburetter 104. Fuel from the pressure controller returns via line 53 and excess fuel from the carburetter returns via line 105. In a modification of this system the pressure controller is arranged in the carburetter excess fuel return line (105), Fig. 4 (not shown) and has its first outlet 52, Fig. 2 omitted.

Title: Fluid-operated telescopic devices
Inventor: WINDER RICHARD HENRY BRYAN
IPC: E21B19/086
Filed: 1959-12-31
Abstract: 908,133. Percussive drills. DOWTY MINING EQUIPMENT Ltd. March 21, 1961 [Dec. 31, 1959], No. 44440/59. Class 124. [Also in Group XXIX] A fluid-operated telescopic device for a rock drill comprises a cylinder 2 having a piston 4 mounted on a rod 5 so that the area of the piston at the rod end is substantially less than the area at the opposite end, passage means having a pressure inlet 12 adapted to be connected to a source of fluid pressure and leading to the piston-rod end of the piston and a fluid exhaust 13 leading to the opposite end of the piston, a first fluid flow restrictor between the ends of  the piston and a second fluid flow restrictor 17 in part of the passage means, at least one of the restrictors being controllable for varying the fluid flow through the passage means and therefore the pressure drop across the piston, whereby the resultant force acting on the piston is variable both in direction and magnitude. The first restriction may consist of an axiallymovable tapered rod in a bore through the piston, the clearance formed by the space between the piston and cylinder, or radial or axial grooves in the bore of the cylinder. The rod end of the piston is connected by the annular space 10 between a tube 8 and the hollow piston-rod 5 to a chamber 11 connected to the pressure inlet 12, and the other side of the piston is connected by the tube 8 to a chamber 9 having a passage 15, which is controlled by a needle valve 17 and forms the second restriction, connected to the exhaust 13. The valve 17 is axially adjustable by a pin 22 connected to a sleeve 19 axially movable by a nut 18 screw-threaded to the housing 6 of the valve. The device may serve as a strut for a rock drill and at one end be fitted with a socket 1 for a spiked foot and at the other end have a male bayonet fitting 25. When the valve 17 is closed, the pressure on opposite sides of the piston will be substantially equal and, because of the differential areas, the device will expand. When the valve 17 is fully open to permit a flow of fluid, the pressure drop across the piston will cause the pressure on the rod end of the piston to be greater than that on the other so that the device closes. Settings of the valve between the fully open and fully closed positions will determine the direction and force exerted by the device. The bore of the cylinder may be stepped so that the clearance between the piston and cylinder varies according to the position of the piston to vary the speed, or to stop, the piston. A further valve may be provided to control the resistance to the flow of fluid to suit fluids of different viscosities.
