Title: Method of making yarn and yarn produced by the method
IPC: D02G3/34
Filed: 1974-02-11
Abstract: 1423484 Forming cored yarns SPANCO YARNS INC 11 Feb 1974 06187/74 Headings D1F and D1W Cored yarn is made by drafting a strand of parallel, untwisted, discontinuous fibres e.g. of polyester and/or cotton by passage through a roller drafting unit and, downstream thereof, wrapping a continuous binder strand e.g. a fine, nylon or polyester multifilament strand or yarn, about the drafted strand to form spaced helices therealong, as the drafted untwisted strand moves from the drafting rollers along a predetermined path. The discontinuous fibres are of a length sufficient to be engaged by and extend from the rollers of the unit while the leading ends are being wrapped by the binder strand. A continuous strand of "spandex" (comprising polyurethane) may be incorporated in the drafted strand and wrapped therewith. The fibre-aligning action of the draft rolls may be enhanced by air flowing longitudinally of the drafted fibre strand. As shown, a sliver 10 passes through a drafting unit 10, a guide 16 and a hollow chamber 22 of a bobbin-carrying spindle 20 (at a wrapping station 18) rotated by engagement of a belt 26 with a hub 24 so that a yarn 36 from the bobbin winds about strand 10 at 38. A vacuum source 28 induces an air flow in the same direction as the strand &c travel and also collects any loose lint in the strand. Nip rollers 30 (and/or others not shown) ensure uniformity of the final yarn taken-up on roll 32.

Title: An improved process for obtaining a patterned mechanical finish on woven or knitted fabrics
IPC: D06Q1/08
Filed: 1953-03-06
Abstract: Textile fabrics which are provided with a patterned mechanical finish are treated with shrinking agents which shrink the unpatterned areas to a greater extent than the mechanically patterned areas, and the puckered fabrics so obtained are stretched smooth, more especially during drying.  The mechanical pattern may be obtained by calendering, with or without friction, wih engraved or smooth calender rolls, by embossing or stamping on the stamping calender, or by a combination of these operations, and may be fixed upon nonthermoplastic material by synthetic resin compositions or aldehydes applied to the patterned areas or to the whole fabric, the non-patterned areas being printed with a reserve and the fabric being heat treated after the mechanical operation.  On thermoplastic fibres a permanent mechanical pattern may be obtained without the aid of synthetic resins.  The fabrics may be of cotton, regenerated cellulose, cellulose acetate, polyamides or polyacrylonitrile, and the shrinking agent, which is selected and applied at a temperature and concentration appropriate to the fibres treated, may be potassium or sodium hydroxide or a mixture thereof; sulphuric, hydrochloric, nitric, acetic, formic or phosphoric acid; alkaline or benzene solutions of phenol; alkaline solutions of cresol or xylenol, their substitution products or homologues; dimethyldibenzylammonium hydroxide; tetramethylammonium hydroxide; zinc chloride; cupric ethylene diamine; ammoniacal copper oxide; calcium or ammonium thiocyanate; formaldehyde; acetaldehyde; pyrogallol; benzyl alcohol; thymol; p-butylphenol; acetophenone; acetic acid and hydrogen peroxide or sulphuric acid and hydrogen peroxide. Sodium chloride, Glauber's salt or soda ash may be added to the shrinking agent when treating regenerated cellulose.  The shrinking treatment may be applied with the fabric untensioned or with a tension less than that required to stretch the fabric completely smooth in the wet state. After the shrinking treatment the fabric may be washed and neutralised and may be stretched in either or both direction to an extent sufficient to make the fabric smooth or so as to return it to its original dimensions, and a urea formaldehyde resin composition may be cured upon the fabric in this condition.

Title: Improvements in hydraulic torque converters
IPC: F16H41/26
Filed: 1950-03-15
Abstract: 677,179. Hydraulic torque converters. AKTIEBOLAGET LJUNGSTROMS ANGTURBIN. March 15, 1950 [March 15, 1949], No. 6485/50. Class 69 (ii). In a hydraulic torque converter consisting of at least one pump blade ring 1, at least two turbine blade rings 2, 4 and one or more guide or reaction blade rings 3 and of which one is located between the first two turbine rings 2, 4, the blades of at least the first blade ring reaction member 3 are arranged to have a ratio of inlet edge radius to the maximum distance from the outlet edge of the blade to a tangent to the inlet edge thereof greater than the corresponding ratio of the blades of the turbine blade rings ; the blade length of at least the first blade ring of the reaction member 3 may be greater at the outlet edge than at the inlet edge. The cross-section of the duct between the outlet of the second-stage turbine 4 and the inlet to the pump 1 in the direction of'liquid flow firstly increases, reaching a maximum approximately halfway round the duct, and subsequently decreases ; similar variations are provided in the duct between the first-stage turbine 2 and the reaction member 3. The dotted lines indicate the duct crosssections of prior converters. The shortening of the inlet edges of the reaction blades results in a decrease of the angle between the inlet directions of liquid flow on starting and at the point where the primary and secondary torques are equal whilst the large inlet edge radius of the reaction blades give rise to a decrease of converter maximum efficiency, whereas the efficiency between the turbine and impeller at both low and high speeds is increased so improving the acceleration characteristics. The invention can also be applied to single- and three-stage converters.

Title: Nail strip manufacturing apparatus
IPC: B65B15/04
Filed: 1969-02-06
Abstract: 1,209,861. Making nail strips. FASTENER CORP. 6 Feb., 1969 [20 March, 1968], No. 6529/69. Heading B8C. Apparatus for forming a coiled strip of nails mounted in a plastics carrier web using a U-shaped flexible carrier having an elongated web from the opposite edges of which project two flanges with slots for resiliently receiving the nail shanks, includes a nail transfer mechanism for inserting nails in successive slots in the carrier, a rotatable mandrel, a guideway for feeding the carrier from the nail transfer mechanism to the mandrel, a pair of jaws disposed around the mandrel and movable between an open position and a closed position, means for moving the jaws between said open and closed positions and drive means for rotating the mandrel to coil the carrier on the mandrel. Nail transfer mechanism.-The plastics carrier web 21 is fed to the inlet of the nail transfer mechanism and the edges are folded upwards at 31 to form flanges 24 with nail holding slots 25. The nails 22 are supplied by gravity from a shoot 48 to transfer wheel 44 where they are forced into grooves 45 in the periphery of the wheel, with the same spacing as that bet ween the slots 25. The nails are held in position by guide 51 and at the base of the transfer wheel are forced into the slots 25 of the strip. Ejector 53 running in a radial groove in the transfer reel, removes any nails which "hang up". Cutting mechanism.-The loaded carrier strip is severed by a blade 61 on rotating wheel 60. The wheel has a grooved periphery and is rotated by passage of the nails beneath it. Blade 61 is spring biased into the centre of the wheel, but can be forced outwards by a cone shaped actuator operated by piston and cylinder 69, 70 to cut the strip into the desired lengths. Coiling mechanism.-The coiling mandrel 75 has a plurality of grooves 76 on its surface for receiving the nail shanks. The mandrel is surrounded by the two jaws 78, 79 of a clamp, the jaws being controlled by a cylinder 80 and linkage 81 and biased to the closed position by spring 82. The jaws are maintained in the closed position (Fig. 10) while the first turn of the nail strip is wound on the mandrel and opened by cylinder 80 as the second turn begins. The drive to the mandrel operates through two clutches 85 and 90, which speed up the mandrel after the first turn has been wound. When fully wound on the mandrel, the coil is pushed into tube assembly 41 by a pusher 94 actuated through linkage 97 by cylinder 96.
