Abstract: 1,193,249. Improving the dyeability of polyester fibres. E. I. DU PONT DE NEMOURS & CO. 17 Jan., 1969 [17 Jan., 1968], No. 2954/69. Heading B5B. The dyeability of polyester filaments is improved by sequentially: (a) drawing the amorphous filaments at a temperature below their " apparent minimum crystallization temperature "; (b) effecting limited crystallization of the filaments to increase their tenacity by heating them to a temperature above their apparent minimum crystallization temperature while allowing the filaments to relax no more than 45% of their drawn length; and (c) further crystallizing the filaments to dimensionally stabilize them with an annealing treatment by heating them under tension at a temperature higher than the temperature during relaxation and lower than the softening temperature of the filaments, with the proviso that during the further crystallization, if the filaments are stretched the extent of elongation does not exceed the extent that the filaments were allowed to relax in step (b). As an alternative to step (c) of Claim 1 the filaments may be further crystallized by exposing them to the vapour of a boiling chlorinated hydrocarbon which is a swelling agent for the filaments at the temperature of treatment. The amorphous filaments may be drawn at a temperature within the range 50‹ to 80‹ C., relaxed at a temperature within the range of 100‹ to 180‹ C. while allowing a relaxation of 5 to 45% of their drawn length, and annealed at a temperature of at least 185‹ C. The filaments may be held at constant length and at a temperature within the range of 200‹ to 230‹ C. during the annealing step (c). The polyester filaments may consist of polyethylene terephthalate, poly (p-hexahydroxylylene terephthalate), poly (diphenylolpropane isophthalate), a polyethylene naphthalene dicarboxylate, polyethylene terephthalate/hexahydroterephthalate of which at least 85 mole per cent is polyethylene terephthalate, polyethylene terephthalate/5 - (sodium sulpho) - isophthalate of which at least 95 mole per cent is polyethylene terephthalate, and polyethylene terephthalate/ isophthalate of which at least 85 mole per cent is polyethylene terephthalate.

[Class 103 (v)] In an automatic coupling for vehicles of the kind in which the respective parts are guided into coupling position by means of coacting male and female conical surfaces 32 and 10, 11, Fig. 1, the coupling elements comprise hooks 13 pivoted, e.g. on the female part and adapted to engage pins 24 on the other part, the pins being longitudinally displaceable for the purpose of subsequently tightening the coupling. The arrangement may include either a female member on each vehicle and a separable duplicate male member, or a single male and female member, one on each vehicle, Figs. 1A, 1B, (not shown). The female or socket member 10, Fig. 1, is preferably swivelled to its draw-bar 1 by means of a union comprising a sleeve 3 with an internal rubber cushion 4, and the hooks 13 are mounted on transverse trunnions 12. The male member comprises a tube or bar 19 terminating in a conical nose 32 having a renewable tip 35, a rotatable threaded sleeve 25 being disposed on a reduced portion 21 of the bar 19 for effecting a longitudinal adjustment of a screwed collar 22 carrying the pins 24. Rotation of the sleeve 25 is produced through the medium of a toothed intermediate sleeve 29 engageable with a slidable toothed sleeve 44, which is rotated by means of handles 45 and is associated with a clutch for throwing it into operative or inoperative position. As the tightening is thus accomplished after the coupling is made entry of an operator between the vehicles in the act of coupling is obviated. During the actual coupling operation a transverse bar connecting the two hooks 13 is raised by a ramp 49 on the male element, and then allows the hooks to drop behind the pins 24. Flats 33, 34 on the end of the cone 32 ensure that the male member is carried in correct position for engaging the opposite head. In a modification the hooks are carried upon the male member and the pins on the female, while means are provided to prevent undesired rotation of the screw collar 32 with consequent accidental unlatching of the coupling.

Title: Spinnerets for production of artificial filaments
Inventor: LIDDEL WILLIAM
IPC: D01D4/02
Filed: 1952-12-19
Abstract: A spinneret consists of a number of fine-bore metal tubes which have been fitted into the holes of a perforated rigid metal plate and brazed or welded to the plate in order to hold them rigidly in position.  The tubes may be made by drawing down thicker tubing. The tubes, after being welded or brazed into the metal plate, may be broached or drilled for greater accuracy.  The extended ends of the tubes may have been removed, e.g. by grinding.  A hole of larger diameter in the internal face of the spinneret may taper into the fine tube which constitutes the final extrusion orifice. Alternatively, grooves may be cut in the internal face of the spinneret to guide the spinning solution or melt to the fine-bore tubes.  In the example a spinneret for melt spinning is made by drilling 33 holes of 3.2 mm. diameter in a stainless-steel plate, 7.6 cm. diameter and 6.4 mm. thick.  Into each of these holes a mild-steel tube 9.6 mm. long, an external diameter just to fit the hole and an internal diameter of 0.22 mm. is fitted and brazed into place.  The projecting lengths of tubing are then ground off. The spinnerets may be used in wet, dry or melt spinning and are cheaper to manufacture than spinnerets in which holes of similar length have been drilled.
