Title: Bonded staple fibre yarns
Inventor: CARR PAUL L
IPC: D02G1/02
Filed: 1974-03-21
Abstract: 1495546 Heat-bonding staple fibre yarn IMPERIAL CHEMICAL INDUSTRIES Ltd 3 March 1975 [21 March 1974] 12587/74 Headings D1F and D1W A process for making a bonded staple fibre yarn from a sliver containing at least a proportion of thermally bondable fibres comprises withdrawing the sliver under tension from delivery means by the action of a fluid twisting the tensioned sliver by the action of fluid, activating the bondable fibres in the sliver by heated fluid, forwarding and tensioning the sliver in a stream of heated fluid through a heat treatment duct constructed such that the angle formed by the sliver entering and leaving the duct is at least 70‹ and from which the sliver issues as a bonded yarn at a temperature below the bonding temperature of the bondable fibres and receiving the yarn under tension in collecting or forwarding means. The various steps may be carried out by different fluid jets but preferably by the single fluid jet shown, the heat treatment duct being in the form of a tail pipe 11. Heated compressed air entering through inlet 9 spirals around helical thread 21 thereby drawing the sliver through inlet 17 and twisting and heating it. Preferably insert member 13 is of low thermal conductivity so that stray fibres do not adhere. The fluid jet may draw the sliver from the last pair of rolls of a drafting apron. The arc of curvature and length in inches of specified curved tail pipes are 780‹/30 in., 420‹/30 in., 330‹/30in., 180‹/16in., 85‹/16in., and 77‹/16in. In other embodiments the tail pipe as a sharp or a radiused 90‹ bend or is a straight pipe with a hole in the side through which the yarn is removed. The yarn may be taken up on a cheese. The sliver may comprise a mixture of bondable fibres, preferably 5 to 40% by weight with fibres that are non-bondable under the conditions used or all the fibres may be bondable. The bondable fibres may be conesheath or side by side (e.g. trilobal) composite filaments. Examples (bondable component first) are nylon 6/nylon 66, polyethylene terephthalate - ethylene adipate / poly(ethylene terephthalate and poly(ethylene terephthalate - ethylene isophthalate)/poly(ethylene terephthalate). Thermally bondable homofibres which may be used alone include nylon 66 and poly (ethylene terephthalate). Those which may be mixed with non-bondable fibres are nylon 6 and polypropylene. Fibres which are non- adhesive under suitable conditions are nylon 66, regenerated cellulose poly(ethylene terephthalate) polyacrylonitrile and natural fibres The examples give many numerical details.

Abstract: 1332761 Making clinching clips SIGNODE CORP 17 March 1972 [19 March 1971] 12598/72 Headings B3A and B3Q [Also in Division B8] Clinching clips C, Fig. 1, formed by bending blanks, Fig. 2, about fold lines 16 and provided with pairs of notches 12, 12 and 14, 14 in their respective side-edges 10, are adapted to be assembled into a stack S by being placed side-byside, Fig. 3, and connected together by a pair of filamentary keys 22 which are engaged respectively, preferably with an interference fit, in the longitudinally aligned rows of notches 12, 14. The filaments 22, which are generally of circular cross-section are preferably formed of lowdensity polyethylene and of such a diameter as to be completely housed in the notches 12, 14. The filaments are also sufficiently resilient to allow a stack S to be inserted into a curved shoot, or, to be coiled for use in a compact dispensing unit. Soft wire twine and solder may be used as filament material. A clinching tool 40 for forming a rigid joint 100, Fig. 10, comprises a J-shaped jaw 50 for supporting, as shown, two wires W and a driven clinching blade 52, a magazine 54 associated with the tool housing a stack S of clips. The clip C beneath the blade 52 is sheared off from the rest of the stack as the blade 52 descends toward the jaw 50, the sheared - off clip carrying the cut-off filament segments 22<SP>1</SP> with it. The pair of filament segments 22<SP>1</SP> are compressed between the inner surface of the folded portion of the clip C and the localized region of the wire W, Fig. 9, the filaments 22<SP>1</SP> acting as resilient packing.

Patent GB-135000-A (GB)
IPC: B23Q3/154
Abstract: 135,000. Arter, W. Sept. 10, 1917. Electro-magnetic chucks.-In an electro-magnetic chuck, a series of long narrow spaced bars 8 project upwardly from the face of a plate-like portion 7 integral with the upper end of a core 6 and extending beyond the core on all sides, a frame or pole-piece 2 surrounding the bars 8 being formed with a series of bars 4, which are spaced to accommodate the bars 8. The portion 7 and its bars 8 are separated from the pole-piece 2 and its bars 4 by non-magnetic material 10, which is run in while the chuck is supported in an inverted position, and, after the non-magnetic material has hardened, the work-supporting face of the chuck is machined. A base-plate 12 of magnetizable material forms a rigid connexion between the pole-piece and the core, which is surrounded by a coil 14. As shown, the pole-piece is of rectangular form, and two cores provided with rectangular portions 7 are located within the pole-piece. The chuck may, however, have more than two cores, which, as manufactured, are made standard for the various lengths of chuck. The pole-piece, moreover, may be annular and surround a central chuck element of the form described in Specification 132,543; the bars of the pole-piece and cores, in this case, have radial, instead of parallel, sides. The chuck may be magnetically insulated from the machine by non-magnetic feet 20, or, if clamps are used, by pieces 22, and it may be provided with lining strips 24, 26, 28, and also with a slot 30, which is useful for fixing a worklocating member or for clamping non-magnetic material upon the chuck.

Abstract: 135,167. Gorsky, S. de Procoudine-. Nov. 9, 1918, [Convention date]. Spring-motor actuation; retarding-devices.-An apparatus for closing a cir- .cuit for a pre-determined time, for use in photography and for other purposes, comprises a contactdrum 28 connected with a hand 4 which can be set in any predetermined position on a dial 3, and a clockwork-controlled contactmember 30 which, on the release of a starting-rod 6, slips from a hook or groove on an insulating-member 22 carried by the drum and moves over the drum until it is lifted therefrom by a fixed insulating-member 34 at the end of the circuit-closing period. The rod 6 carries an adjustable contact-member 37 which breaks contact with a plate 35 when the rod is depressed to wind up the clockwork mechanism. On depressing the rod, a stop 7 engages an arm 8 keyed to a wheel 12 gearing with a pinion 13 on a shaft 14 to which is keyed a crank 15 connected to a two-armed lever 26 carrying the lever 27 on which the contact-member 30 is mounted. The arm 8 is moved against the action of a spring 9, and the lever 26 carries the contact-member 30 around the drum 28 to the stop 22, the circuit meanwhile being broken at the plate 35. During this movement, a spring- pressed pawl 16 on the lever 15 slips over the teeth of a ratchet-wheel 18 fixed to a wheel 19 which engages clockwork mechanism 20 controlled by a pendulum 21. On releasing the rod 6, it immediately returns to its original position under the action of a spring 11, thereby re-establishing contact at 35, 37, and at the same time the pawl 16 engages the ratchet wheel 18 so that the return of the lever 26 under the action of the spring 9 is controlled by the clockwork mechanism 20, 21.
