Patent GB-1033605-A (GB)
Title: Woven fabrics
Inventor: MANOCK GEOFFREY WINDLE
IPC: D03D15/56
Filed: 1963-11-25
Abstract: In a woven fabric having stretch characteristics due to yarn crimp in the fabric which has been fixed by a heat treatment in fabric form, the stretch characteristics are imparted in that direction, i.e. in the warp or weft, in which a crimped filament yarn, as hereinafter defined, has been incorporated and in which the yarns in the other direction have substantially no yarn crimp and preferably contain a major proportion of thermoplastic fibres, e.g. polyethylene terephthalate fibres.  The crimped yarns consist of thermoplastic synthetic linear polymer filament yarns which impart at least 15% stretch in a suitably woven fabric and which have been subjected to a crimping operation as a result of which the yarns, having an initial denier of 40-250, develop crimp and bulk in woven fabric form during finishing operations.  The yarns are capable of shrinking at least 15-50% or more when placed in boiling water for one minute and simultaneously develop crimp and bulk by curling up.  Subsequently, on applying a load of 0.04 g.p.d., the yarn will retract 90-100% on removal of the load. Specified yarns are nylon, polyester, e.g. polyethylene terephthalate or a copolymer of polyethylene terephthalate with up to 10% of another polyester, and polyacrylonitrile or a copolymer thereof with up to 20% of another polymer.  The woven fabric is overfed or relaxed by 5-20% in that direction in which the crimped filament yarns are situated, e.g. when entering a stenter, and stretching the fabric 4-15% in the other direction to bring about yarn crimp interchange.  The fabric is heatset for a suitable time and at a suitable temperature and then allowed to cool.  The treatment superimposes yarn crimp on filament crimp. The treated fabric can be elongated by at least 15% in the direction of the crimped filament yarns under a load which must be below the elastic limit of the yarn crimp and does not cause fibre rupture and this elongation is recoverable by at least 85%. Textile lubricants containing silicones may be used on the surfaces of the fabric yarns.  Stretch may be imparted on apparatus identical with that described in Specification 983,968. A fabric may be given a crease-resisting treatment at a first temperature of at least 30 DEG C. below the melting point, followed by one of the stretch-imparting treatments at a second temperature of at least 60 DEG C. below the melting point; the first and second temperatures may be equal.  A durable pleat can be subsequently inserted in a garment made from the fabric at a third, lower, temperature on a Hoffman press.

In a method of providing a drum core with a continuous groove having helical and parallel sections in sequence, a sleeve 10, which is of a diameter to fit over the core and which has parallel grooving around its outer periphery, is severed into segments of complementary wedge shape, 40, 42 and 46, 48 which are secured in reverse order to the drum core together with segments 38, 44 to provide the continuous groove. Arcuate end filler bars are used to fill the gaps between the ends of the sleeve and the flanges of the drum, and to assist in the formation of the second cable layer. The width of the sleeve may be the same as the width of the drum to provide an " alternate rise grooving " or half a cable diameter less to provide a " conventional rise grooving." In either case part of one turn of the sleeve is cut away. Alternatively, from Fig. 2, cuts 26, 28, 30, 32 may be inclined to the axis of the sleeve with cuts 34, 36 parallel to the axis to provide a " bias cross-over " grooving system.

Abstract: 1,120,417. Feeding webs. BEHALTERUND MASCHINENBAU MITTWEIDA, VEB. 4 Nov., 1965, No. 46880/65. Heading B6B. [Also in Division B8] An apparatus for conveying foil webs to capsuling machines has a ratchet mechanism connected with each capping device which feeds the web in steps. Several capping devices, such as shown at 2, revolve around a central main shaft 1. Each capping device 2 has a web feeding apparatus for conveying the foil 3 beneath it. The main shaft 1 drives through gears, &c., 4 . . . 8, to a crank arm 9. The crank arm 9 is connected to a pawl 10 which steps round a ratchet wheel 11. The stepping movements are transmitted through gear wheels and sprockets 13, 14, 17, 18 to drive rollers 16, 19, feeding the web. As the capping device 2 rotates around the axis, a lever 26 is raised as it abuts a stop 30. This movement displaces a resilient masking control 28, connected to the lever 26, and allows the pawl 10 to engage the ratchet wheel 11 under spring bias. The movement of the crank arm 9 pulls the pawl 10 and the ratchet wheel 11 to the position b. The crank arm 9, then pushes the pin 29 on the pawl 10 back along the outside of the masking control 28, and hence the ratchet wheel is disengaged.

Abstract: 1,201,952. Step-by-step jacks. H. LAMPERT. 16 Oct., 1967 [20 Oct., 1966], No. 47015/67. Heading B8J. [Also in Divisions E1 and E2] A linearly adjustable telescopic device, Fig. 1, comprises a base element 1 and a load supporting element 4 arranged concentrically and for telescopic movement, and first and second coaxial coupling-carrying members 2, 3 concentric with the elements and each carrying a respective one of first and second disengageable one-way frictional couplings 5, 6 which are normally in coupling engagement with the same one 4 of said elements, the first coupling- carrying member 2 being movable away from the second coupling-carrying member 3 to move said same one 4 of the elements relative to the other of said elements 1 and the second coupling- carrying member 3; and the second coupling- carrying member 3 being normally stationary with respect to the other of said elements but cooperating with the first coupling-carrying member and the other of said elements so that movement of the first coupling-carrying member against the second coupling-carrying member disengages the first coupling from said same one of said elements and then causes the second coupling-carrying member to move against said other element to disengage the second coupling from said same one of said elements. As shown the member 3 includes a cup 7 into which a head 8 of the member 2 can move so that a knife edge 11 of the cup abuts the coupling 5 to disengage it from the drum 14. The downward movement of the member 3 also causes downward movement of the member 2 which engages the coupling 6 against a knife edge of the element 1 so causing its disengagement from the member 4. The member 4 can then move downwardly relative to the member 1 under the influence of gravity. Movement of the member 3 relative to element 1 is limited by a pin 13 engaging a slot 14 in element 1. In a modified construction the cup 7 instead of being rigidly connected to the member 3 is supported on it by a coil spring and there is a ball coupling between the element 1, and members 2 and 3 which aids the operation. In a further construction the element 4 is a rod instead of a tube and this is surrounded by the element 1 which in turn is surrounded by the member 3, the rod like member 2 of Fig. 1 being substituted by a cup-like member which slides relative to a reduced portion of the tubular member 3, the couplings 5, 6 engage respectively between the rod 4 and the member 3 and between the rod 4 and the cup-like member as in the first construction and the operation is similar.

The extrudate may be in the form of a rod or tube, or of a board whose surfaces are rapidly cooled to-form skin layers before effecting step (b) above. In the examples mixtures of polyethylene, ethylene/butene copolymer, polypropylene or polystyrene with calcium carbonate, clay or zinc white as nucleating agent and trichlorofluoromethane or butane as foaming agent were extruded through a slit or rod-shaped die to form boards or rods.
