IPC: F02M69/26
Filed: 1971-11-05
Abstract: 1374444 Fluid-pressure servomotive systems ROBERT BOSCH GmbH 5 Nov 1971 [7 Nov 1970] 51461/71 Heading G3P [Also in Division F1] The pressure acting on the end-face 9 of a spool 6, controlling the delivery of fuel through metering slots 21 to a plurality of fuel injectors and acting on the pivoted lever 4 of an air-flow measuring element 2 in an I.C. engine intake manifold I to provide a restoring force for the element, is controlled by a pressure regulator 33. The regulator has a diaphragm 37 co-operating with a valve seat 36 to define a valve controlling fuel-flow from a pump 10 back to a tank 12. The diaphragm 37 is connected by a pin 38 to a diaphragm 39 biased by a spring 40 and subjected on opposite sides to the air-pressures upstream and downstream of the element 2. The diaphragm 37 is subjected to the upstream air-pressure and the fuel pressures upstream and downstream of the seat 36 over differential areas. The force exerted by the spring 40 may be controlled by a member 50 which increases the spring force with increasing engine temperature, a three-dimensional cam (53), Fig.2 (not shown) positioned in accordance with throttle valve position and the vacuum downstream of the throttle valve 3, a cam plate (63), Fig.3 (not shown), moved axially in accordance with the vacuum or a cam (66), Fig.4 (not shown), rotated with the throttle valve. To maintain the pressure across the slots 21 substantially constant a diaphragm 20, subjected in chambers 18, 19 to the pressures upstream and downstream of the slots, provides the movable part of valves controlling fuel-flow to the ducts 23. The air-flow measuring element may be a piston displaceable transversely to the direction of air-flow. Reference has been directed by the Comptroller to Specification 1231967 and 1250345.

Abstract: 1,136,360. Brakes. GENERAL MOTORS CORP. 23 Nov., 1967 [22 Dec., 1966], No. 53313/67. Heading F2E. [Also in Divisions G1 and H1] An indicator lamp is associated with the hydraulic fluid of a vehicle to light up when the fluid level is low, and when a mechanical brake lever is operated. The brake drum 14 (Fig. 1) on each wheel carries two brake shoes 12 operable by a spreader bar 30 linked to a brake pedal 24, or by fluid cylinder 16 fed by master cylinder 18, controlled by brake pedal 23 operating on rod 22 in piston assembly 20. Brake pedal 24, used when parking, also operates switch 44 to light lamp 36. Cylinder 18 carries a liquid level sensing device 48 comprising a cylindrical N.T.C. thermistor 72 (Fig. 2) coated with a layer of resistance material 78 to be used as a heater, the end faces of the cylinder being coated with nickel electrodes 74, 76.

Title: Production of filled sealed containers
IPC: B65B3/02
Filed: 1973-11-20
Abstract: 1408682 Forming; filling and sealing containers PMD ENTWICKLUNGSWERK FUR KUNSTSTOFF-MASCHINEN, GmbH & CO KG 20 Nov 1973 [20 Nov 1972] 53766/73 Heading B8C [Also in Division B5] A method of producing a filled sealed container comprises inserting a portion of a tube 11 of synthetic thermoplastics material into a divided blow mould 12 provided with separately displaceable top mould halves 13, sealing the tube at its bottom end, inflating and filling the tube, sealing the tube section at its top end within the closed top mould halves 13 and applying an external pressure to at least one portion of the bottom, and/or side, wall of the container thus formed to press the said wall portion into the interval space of the container whereby, as a result of the overpressure thereby generated within the internal space of the container, the top wall portion of the container, which still retains its plasticising heat, is pressed against the moulding surface of the said top mould halves 13. As shown, a length of tube 11 of synthetic plastics material, e.g. polyethylene, or P.V.C., is extruded into the space between the two halves of the split blow mould 12 which has the pair of container top mould halves 13 superposed by two vacuum-type tube holder segments 14, and a cutter mechanism, not shown, and, after the mould 12 is closed, the tube is cut off and a mandrel 26 is inserted and sealed into the upper end of the tube 11 which is held open by the segments 14. Compressed air is then fed from a feed pipe 27 to the mandrel 26 to expand the tube in the bottle-shaped chamber 16 of mould 12 and form a liquid-tight container 31, whereupon the filling valve 29 of a liquid supply pipe 28 is opened to fill the container. The top mould halves 13 are subsequently closed so that their upper edges 20 seal the upper end of the tube 11 and cut off the tube scrap held by the holder segments 14. A surge of compressed air is then fed from a pipe 24 to a distributor chamber 21 in the mould 12 and through a ring of passages 22 into the chamber 16 beneath the container bottom 16 to press the latter inwards and expand its upper end, which is still plasticized, into contact with the upper mould surface, Fig. 6, to form the container neck. The external pressure also tears off the lower tube scrap 33. If the tube were to puncture, as at (30), Fig. 3 not shown, the inflating air flows through the fluid pipe  system 21-24 and actuates a contactor, not shown, which ensures that the filling valve 29 remains closed. The upper tube scrap may be cut off by apparatus controlled by compressed air instead of by the mould halves 13. In a mechanical arrangement a portion of the moulding surface may be displaceable into the moulding chamber.

Cross beams 64, 64<SP>1</SP> are mounted on the outer ends of the inner and intermediate beams and oppositely directed piston and cylinder units 88, 90 are connected between the outer beam and the cross beam to effect the extension and retraction of the spreader. A frame actuated latch (104) Fig. 6 (not shown) engages in a selected aperture of a series of apertures in the inner and intermediate beams to lock the spreader at a desired extension. Further cross beams 66, 68 have a hook 194 pivotally mounted at each end thereof and movable by a piston and cylinder unit 204 for engagement with the corner castings on a freight container. The pivot point 200 of each hook is vertically displaceable to accommodate different positions of the holes in the corner castings. The spreader is suspended by cables 57, 59 from cross beams 54, 56 carried by hydraulic rams 50, 52 mounted on the limbs 12, 14 of a U-shaped chassis of the carrier and is guided during its vertical displacement under the action of the rams 50, 52 by guide beams 60, 60<SP>1</SP> extending transversely thereof and carrying sliders (78) Fig. 3 (not shown) which engage in guides (76) secured to the limbs 12, 14. Hydraulic rams 156 act between its outer beam 74 and each of the guide beams to effect slewing or side sifting of the spreader relative to the chassis.
