Title: Control valve arrangement for a pneumatically operated actuator such as a pneumatic stapler
IPC: B25C1/04
Filed: 1972-09-11
Abstract: 1355929 Fastener driving tools BUKAMA GmbH HANNOVER 11 Sept 1972 [10 Sept 1971] 42061/72 Heading B4C [Also in Division F2] A pneumatically operated stapler or nailing device comprises a magazine 10 from which the staples or nails are projected by a blade 7 when compressed air from a reservoir 2 is admitted into the upper end of a piston cylinder 4. The air passes into the cylinder through a passage 17 and ports 41 and displaces a piston 5 to which the blade is attached. The pressure of air temporarily trapped beneath the displaced piston returns it to its uppermost position where it is retained by a magnet 39. The supply of air to and from the cylinder 4 is controlled by a valve arrangement (see Division F2) in which radially deformable elastic rings 19 and 33 are used to control the supply of air to and from the cylinder. The rings themselves are deformed into sealing positions by compressed air supplied through an auxiliary valve 41. A trigger 25 actuates the auxiliary valve.

Abstract: 1374173 False twist crimped yarn MITSUBISHI RAYON CO Ltd 18 Sept 1972 [20 Sept 1971 19 July 1972] 43137/72 Headings DID and D1F A method for producing crimped synthetic thermoplastic yarn wherein the yarn is passed through a twisting tube to apply false twist, is carried out under conditions satisfying the following relationships:- where V= yarn speed in m/min at the twisting surface; S=surface speed in m/min at the centre of the yarn engaging portion of the twisting surface; D=denier of treated yarn; T 1 = tension of yarn in grams at the inlet side of the twisting tube; and T 2 =tension of yarn in grams at the outlet side of the twisting tube. The crimping process is carried out at speeds in excess of 300 m/min and is said to provide a uniformly crimped yarn. The yarn may be polyester or polyamide and may be drawn prior to or simultaneously with false twisting. In a preferred embodiment, an undrawn yarn 1 is fed via rolls 2 through a heater 4, cooling roll 5, friction twist tube 6 and draw rolls 7 and is wound on a bobbin 8. A diagram is given relating the ratio V/S to the denier D of the   treated yarn and giving examples which satisfy the above conditions.

Abstract: 1,068,737. Winding cores with wire. ORION RADIO ES VILLAMOSSAGI VALLALAT. Nov. 4, 1963 [Nov. 2, 1962], No. 43445/63. Heading B8G. A winding arm 6 wraps an insulated wire 8 around a half-ring core 1 whilst the core is displaced about its radial axis, the movement of the core 1 being effected by a cam 14 that causes the core to move slowly in one direction during a wire winding period and to move rapidly back to its starting position during a non-winding period. The inclined faces of the cam 17 are used to move the core 1 at a desired rate during a winding period and the radial faces of the cam 17 permit a spring 23 to pull the core rapidly back to its starting position. Just prior to the cam follower 15 reaching the end of an inclined cam face a further cam 17 contacts an electric switch 18 to change a gear setting 24 in a manner reducing the winding speed of the arm 6 to about one ninth of normal. At the same time an electromagnet 28 causes the cam follower 15 to be locked in order, as the cam 14 rotates further, to prevent the jumping of the cam follower 15 into the recess in the cam 14 until such time as the winding arm 6 has turned below the horizontal on the outside of the core 1. When the winding arm 6 has turned below the horizontal a pair of slide contacts 33 are bridged by a metal insert on a winding disc 5 carrying the winding arm 6 and this releases the electromagnet 28 so that the cam follower 15 can jump into a recess in the cam 14. In this manner the cam follower 15 is prevented from jumping into a recess immediately it reaches the end of an inclined surface of the cam 14 and in this way any difference due to manufacture and shaping and to end wear of the cam 14 are eliminated and cannot influence the start of the carrying back of the wire.  A hook 21 holds the wire in position at one end of the core 1 whilst the core moves back to its starting position and during this period a wire-reversing wedge 21 is pressed by a leafspring 36 against the coil. The apparatus is stated to be suitable for winding multi-layer deflecting coils on a ferrite core.

During half-cycles of A.C. from the ringing generator UR which aid the feed battery UB the capacitor C11 is charged, but as the voltage on the line diminishes the control potential of S1 becomes such that it conducts and allows the capacitor C11 to discharge, thus providing A.C. for operating the bell W1.

The capacitor C21 serves to delay the rise of control potential applied to S1 should one subscriber be called immediately after the other has hung up.
