Title: Improvements in the production of crimped staple fibre
IPC: D02G1/18
Filed: 1966-05-26
Abstract: 1,126,552. Crimped staple fibre. FIBER INDUSTRIES Inc. 26 May, 1966 [4 June, 1965], No. 23554/66. Heading B5B. Crimped staple fibre is made from synthetic thermoplastic polymer filaments which exhibit asymmetric birefringence differentials across their diameters, by cutting the filaments into staple fibres, and feeding this into a stream of an unreactive gas heated to a temperature above the second order transition temperature of the polymer, but below its m.p., the stream of gas having a sufficient velocity to maintain the fibre in suspension, and the fibre being kept in suspension until it becomes crimped. Polyethyleneterephthalate is exemplified, using air as the unreactive gas at 140-180‹ C. Other polyesters are also mentioned. The filaments used in the process may have been obtained by conventional spinning, but with an asymmetric cooling step included. In the examples the filaments are drawn before being cut and crimped.

Patent GB-615395-A (GB)
Title: Improvements relating to the production of factices
Filed: 1946-08-12
Abstract: In the manufacture of factice from fats or fatty oils and sulphur, a relatively small proportion of iodine is added prior to heating, which enables the reaction to be carried out at appreciably lower temperatures than normally used and produces a factice which does not appreciably depress the tensile strength and elongation at break of cured rubber compounds to which it has been added, and also maintains a low modulus.  From 0.05 to 2.0 per cent of iodine may be used.  The iodine may be used in conjunction with the accelerators described in Specification 588,353.  In an example, refined rape oil 100 parts, sulphur 25 parts and iodine 1 part are heated at 160 DEG  C. with stirring until gelation occurs in about 30 minutes.  A rubbery dark-brown mass containing 1.9 per cent sulphur is produced as compared with one containing 4.1 per cent sulphur without the use of iodine.  A typical rubber mix containing the product is exemplified (see Group V).ALSO:Factice which has been produced by heating fats and fatty oils with sulphur in the presence of a small proportion of iodine [see Group III], is employed for incorporation with rubber and is stated not to depress appreciably the tensile strength and elongation at break of the cured rubber compounds while maintaining a low modulus.  In an example, a rubber mix made from factice prepared according to the invention comprising rubber 100 parts, zinc oxide 5, stearic acid 2, activated calcium carbonate 78, sulphur 2.5, mercaptobenzothiazole 1, and factice 50, is press vulcanised at 126 deg. C. for 45 minutes and has a modulus at 500 per cent elongation of 1,000 lbs./sq. in., a tensile strength of 2,060 lbs./sq. in. and an elogation at break of 680 per cent. as compared with figures of 1,235, 1,570 and 565 for the last three items in a similar rubber compounded with standard dark factice.

Loom beat-up motions; reeds; shuttle-races; lays; weft, deflecting for slackening.-After a weft z, Fig. 6, has been inserted by the shuttle. the shed closes lightly. A number of undulators or rocking members 13, 8, 6 are then turned in succession about an axle 1 passing through holes in the reed dents 2, 4 so as to move between projections 9 on the reed dents, the weft being thus caused to assume an undulated form and the extra length necessary to produce this form being withdrawn from the shuttle. The undulators are rocked in succession by means of a member 18, 19, Fig. 7a, with an inclined part 19 mounted on an eye on a sliding carriage, which is moved from one end to the other of the batten by a chain or rope or otherwise. When the sliding carriage moves in one direction, rollers 20, Figs. 6 and 7<a>, on the member 18, 19 mount two pivoted spring- controlled tongues or points 52 forming extensions of rails 14, 15 on the batten, and the member slides on these rails so as to act on the rounded parts 8 of the undulators and rock these in succession. The member finally falls through apertures in the rails, and on its return movement displaces the tongues 52. The undulators have extensions 13 actuated bv a cam-controlled rod 22 to cause them positively to resume their non-working position in due course. The reed comprises stamped steel sheets 2, 4 reinforced by riveted plates 3 and with notches 5 for engaging their supports. The reed finally beats up the undulated wefts. A modification is described wherein the weft is formed into an undulated shape by means of a series of rocking undulators and a series of rocking separators actuated by means of cam links on an endless chain. The reed is held in position on the batten by a steel member and set screw. A member on the batten is provided with cast-iron supports connected by rods and screws and bolts to the steel member, these rods serving as a shuttle race. The weaving is stopped during the operation of the undulators and is then re-started. The Specification as open to inspection under Sect. 91 (3) (a) states that the sliding carriage may be operated by a cam or lever. This subjectmatter does not appear in the Specification as accepted.
