Abstract: 1,040,154. Hydraulic shock absorbers. GIRLING Ltd. Dec. 6, 1962 [Dec. 16, 1961; March 3, 1962], Nos. 45180/61 and 8318/62. Heading F2S. A telescopic hydraulic damper comprises a piston 13 which works in a cylinder 10 closed at one end by a member 11 and which has a rod 14 which extends into the cylinder 10 through a bore in a bush 15 which is axially slidable in the other end of the cylinder. The bush 15 carries a high-pressure seal 16 which cooperates with the rod 14 and the inner surface of the cylinder 10. A coiled compression spring 18 surrounds the rod 14 and is constrained between abutments 17, 19 on the outer ends respectively of the bush 15 and the rod 14 the latter also carrying a dust shield 22 which is guided at its inner end by an annular seal 23 clamped against the abutment 17 by the spring 18. In a modification, Fig. 2 (not shown), which incorporates means for maintaining a vehicle at a substantially constant height, a piston rod 33 extends through a fixed closure 32 at one end of a cylinder 31 the other end of-which is closed by an axially-slidable, hollow sleeve 41 which has end flanges 43, 44 the flange 43 carrying an 0-ring seal 42. A spring ring 45, located in an annular groove in the cylinder 31 limits the axial movement of the sleeve 41 in both directions. A pump piston 47 works in a tube 46 mounted in the sleeve 41 and, during compression strokes, co-operates through its rod 48 with the corresponding end of the rod 33 to draw fluid from a reservoir 55 in the sleeve 41 through a non-return valve 54 in an end plate 49 for the sleeve 41 and into an annular space around the piston rod 48. On extension of the unit a spring 56 moves the piston 47 in the opposite direction so that fluid is pumped from the annular space through bores 53, 51 in the rod 48 and past a non-return valve 52 and into the cylinder 31. This action continues by relative movement between the piston 35 and the cylinder due e.g. to the suspension movements of the vehicle until a port in communication with the bore 51 communicates with a valve in the end plate 49. In a further modification, Fig. 3 (not shown), the piston 47 pumps fluid from a reservoir 55 through a oneway valve 61 into the tube space 46 and from the latter through a one-way valve 59 located in the piston at the inner end of the bore 51. In both embodiments the reservoir accommodates a flexible bag 62 filled with air or gas. A rubber or air spring may replace the spring 18, or 36.

Abstract: 1322921 Cable strippers GENERAL ELECTRIC CO 24 Sept 1970 [29 Sept 1969] 45539/70 Heading H2C A machine for cutting an insulated conductor to a desired length and stripping the insulation from both ends comprises an electric motor 41 driving drive wheels 31, 32 which drive endless belts between which the insulated conductor 41 is carried. The length of conductor fed is measured by a device 25 comprising a light directed through an apertured wheel 59 attached to drive wheel 31, the length desired being preset by hand or by numerical control. After the desired length of conductor has been fed actuators 79 are energized to drive together heads 81, 83 carrying cutter heads 85 to sever the conductor and insulation cutting heads 87, 89 to cut the insulation on each side of the plane of severance. When the heads 81, 83 have come together the bevelled ends of two camming members 101, 102 abut and member 102 is forced up against a spring and triggers a switch 99 which energizes actuators 79, which drive together clamps 113 which triggers switch 119 via camming members 121, 122 and spring 123. The heads 81, 83 are mounted on one carriage 69 movable on rails 67 by an actuator (95, Fig. 2, not shown) mounted on the machine frame, and the clamps 113 are mounted on a second carriage 105 movable by an actuator (115, Fig. 2, not shown) mounted on this second carriage whose piston is connected to the first carriage. When the switch 119 is triggered it energizes both carriage actuators. The insulation cutter heads 87 strip the insulation from the end of the conductor held between the now stationary belt 27, 29 and, as the carriage holding the clamps 113 moves further than the other carriage the insulation cutter heads 89 strip the insulation from the end of the cut conductor. When the carriage 105 reaches the limit of its travel it triggers switch 129 which releases the cutter heads and clamps and the conductor falls into the shoot 23. The switch 129 also resets the machine to begin a further cycle. The belts 27, 29 are pressed together by springs 51 acting on a pressure member 45 on which an idler gear 34 for the belt 29 is mounted, this being retractable for feeding in the start of the conductor. A further switch 127 may be used to indicate when the carriage 69 moves away from its home position and the two actuators for the carriages may be replaced by one driving directly carriage 105 and driving 69 through a lost motion device.
