Title: Manifolding carbon supply pack
IPC: B41L1/16
Filed: 1958-09-09
Abstract: 865,548. Carbon paper arrangements. FLEISCHMANN, L. K. Sept. 9, 1958, No. 28900/58. Class 16. A carbon paper pack, for use with continuous stationery strips, from which fresh lengths of carbon paper can be withdrawn comprises a bottom carrier sheet 10, Fig. 2, provided with a pocket to receive a holding bar for retaining the pack on a manifolding machine, a top carrier sheet integral with the bottom sheet, and a continuous carbon strip 24, zig-zag folded upon itself along fold lines 16 to provide offset portions 21 which are adhered to the carrier sheet 10 by an adhesive which becomes tacky when heated. A rod 22 is secured to the forward portion of the sheet 10. In use, the operator grasps the rod 22 and moves it towards the dotted line position, to pry the carbon strip 24 and sheet 10 apart at the first offset portion 21, so that a fresh length of the carbon strip can then be drawn from the pack. In the form shown in Figs. 3 and 4, the pack comprises bottom and top carrier sheets 40, 41 secured to a holding bar 14 for retention on a machine, and a zig-zag folded carbon strip 49 with offset portions secured by pressure-sensitive adhesive to a tape 46, the latter carrying at the forward end a paper tube 50 within which is a square rod 51, and the rear end 47 of the tape 46 is adapted to adhere to the flap 41 when the latter is folded down. In use, the leading end of the carbon strip 49 is held taut while the rod 51 is rotated to roll the tape 46 on the tube 50, thus prying the first offset portion 53 of the carbon strip from the tape, whereupon a fresh portion of the carbon strip can be withdrawn from the pack.

Title: Improved hydraulic piston-actuating apparatus
IPC: B25D9/12
Filed: 1963-07-23
Abstract: 1,042,349. Percussive tools. THOR POWER TOOL CO. July 23, 1963 [July 31, 1962,] No. 29096/63. Heading B4C.  An hydraulically-actuated percussive tool, such as a rock drill, comprises a piston 23 reciprocable in a cylinder 25 between first and second terminal positions and having small and large operative areas 59, 60 respectively, the smaller area being permanently acted upon by fluid pressure so as to urge the piston toward the first terminal position, and a valve 39 for intermittently placing the larger area in communication with the pressure source so as to urge the piston toward the second terminal position against the action of the biasing pressure. The cylinder is mounted in a housing 21 including ports 49, 51 and 52 connected to the pressure fluid and ports 44, 45 and 46 connected to the return back to the supply reservoir. The valve spool is slidable in a cylinder 38 mounted in a housing 22 and is normally biased to the position shown by pressure fluid acting on the end 40 of the spool via port 50 and passage 52. In operation, when a control valve is actuated, pressure fluid is fed, via the port 49, to act on the small area 59 defined by a land 56 on the piston. The piston then moves to the right, causing the fluid in front of the larger area 60 defined by a land 57, to be forced back to the reservoir via ports 66, 68, annular passage 69, ports 70 and 45. When the land 56 passes a port 71, the pressure fluid flows via ports 72, 73, into a chamber 40 so as to act on the large end 41 of the spool valve moving it to the right and thereby causing a land 74 thereon to cut-off the return flow. Pressure fluid is now able to flow via ports 51, 78 anular chambers 77, 69, ports 68, 66, to act on the large area 60 of the hammer piston to thereby drive it on its working stroke. Pressurized fluid for clearing the tool bit is fed via a pipe 32 and port 33. The tool is also rotated by means of an independent hydraulic mounted on the housing 21.

Title: Improvements relating to the production of insulating coatings by spraying asbestos fibre
IPC: E04F21/12
Filed: 1946-10-02
Abstract: <PICT:0617468/III/1> <PICT:0617468/III/2> <PICT:0617468/III/3> Mineral fibres are supplied to a spraying device by a process characterised in that the fibre which, in passing through an apparatus in which it is opened up and from which it is discharged as particles in a current of air, is formed into a thin layer which is sprayed with an atomized jet of water or other damping agent before it is suspended in air and the spraying is controlled in accordance with the flow of fibre through the apparatus.  Referring to the drawings, a drum 10 forms the upper roller for an endless belt conveyer 11 which also passes over roller 12.  The drum 10 is driven by motor 15 connected by belt 16 to shaft 23 normally free to rotate and carrying wheel 24 with holes 28.  When plunger 26 is inserted in any of the holes 28, shaft 23 cannot rotate and hence drum 10 revolves; on removal of the plunger the frictional resistance of drum 10 and conveyer 11 causes the gear to drive the shaft while the drum and conveyer stop.  Conveyer 11 which carries a series of spokes 34 picks up asbestos fibre from hopper 42, carries it past bush 35 which removes all but a thin layer, past damping chamber 41 where spray nozzle 44 delivers an air-atomized spray of water on to the fibre, and on to stripping brush 60 which removes the damped fibres which then drop down ducts 80 and 81 and are delivered by air fan 82 to spraying device 85.  From this device the fibres are sprayed, at the same time as an aqueous rubber emulsion, by <PICT:0617468/III/4> <PICT:0617468/III/5> <PICT:0617468/III/6> the action of compressed air delivered through pipe 87.  Duct 80 lies wholly within the mouth of duct 81 which is itself surrounded by hood 90 so as to leave an annular opening 91 through which air is drawn in by fan 82.  The apparatus is so constructed that the asbestos before damping travels through a substantially closed casing.  Operation is controlled by a single operating handle 95 connected to a double valve controlling the flow in pipes 86 and 87.  Pipe 96 carrying plunger 26 branches from pipe 86 and runs to cylinder 27 which contains piston 98.  When air is allowed to flow in pipe 96, this piston 98 is forced against spring 99.  Thus, whenever handle 95 is turned to stop the spraying of the fibre, plunger 26 is withdrawn, wheel 24 turns and the belt is stopped. Pipe 48 runs from cylinder 27 to nozzle 44 and whenever the conveyer is stopped, the air to nozzle 44 is also stopped.  The p water spray is then stopped because needle valve 50 is moved by diaphragm 51 to close orifice 49.  Specifications 368,368 and 583,077 are referred to.

Abstract: 854,832. Starting oil engines. SIMMS MOTOR UNITS Ltd., DUNN, H. G., and NORTH, G. R. Nov. 24, 1958 [Sept. 23, 1957], No. 29884/57. Class 7(3). The normal maximum delivery stop 27 for a fuel injector pump control rod 47 is moved sideways by an arm 36, whereupon a spring-loaded latch 42 moves forward temporarily to prevent the stop 27 returning to its initial position and permit the rod 47 to move past its normal maximum position, Fig. 6, to a starting position, Fig. 10. The arm 36 is carried by a rotatable casing 22, Fig. 3, spring-loaded by a torsion spring 37 to a position in which it holds an auxiliary stop 28 away from the latch 42. The stops 27, 28, Fig. 5, are pivoted at 29, 31, and urged by a leaf spring 32 towards the latch 42. Prior to starting, casing 22 is rotated clockwise to dislodge stop 27, the stop 28 moving to a position in which it limits the forward movement of latch 42 and the stop 27 being held by its spring against the side of the latch 42. On release of the casing 22 it returns, along with stop 28, to its normal position and the control rod 47 is moved by its loading spring to its starting position, Fig. 10, in which it forces the latch 42 back. When the engine starts the rod 47 immediately moves to the right and the stop 27 returns to its normal position.
