Filed: 1924-09-11
Abstract: 239,051. Chubb & Sons Lock & Safe Co., Ltd., and Butter, F. J. Sept. 11, 1924. Locks, permutation; locks, cases for; reversible locks; multiple-bolt fastenings. - The notched locking discs of a permutation lock are mounted symmetrically about the horizontal axis of the casing in order to render the lock reversible for doors of either hand, and are associated with a lever pivoted on the bolt for locking or operating it. The bolt m, Figs. 1 and 2, has upper arms m<1>, m<1x> and lower arms m<2>, m<2x> which slide past the standard n on the casing b as the bolt moves. The arms m<1x>, m<2x> slide in guide grooves b<2> in the casing wall. A lever k having a lug k<1> which drops into notches d<1> in permutation discs d when these are set, as shown in Fig. 1, is pivoted between the arms m<1>, m<1x>. The discs are set by to-and-fro rotation of a knob f turning a graduated disc g over a ring h. A smaller disc j at the end of the actuating spindle i carries a projection j<2> which engages in a notch in the lever k to withdraw the bolt and also serves to lift the lever out of engagement with the discs d on continued reverse rotation to scatter the combination after shooting the bolt. When the lever k is lifted, it blocks the bolt by engaging the rib b<1> on the casing. The discs are duplex and when set so that the keyholes d<2> in their outer parts 4 are aligned with a hole s in the casing, a square key can turn the cam 2 to allow spring-rocked levers 5 on the parts 4 to disengage the inner parts 3, allowing the combination to be changed. The cover plate c carries a pin c<1> with a projection c<2> engaging a notch n' in the standard n ,and is secured by a grub screw n<2>. To release the cover plate the notches d<1> are aligned with the pin c' so that the cover plate can be moved sideways after removing the screw n<2> to disengage the lug c<2> from the notch n'. The lock is readily adapted for right or left hand doors by taking off the cover plate and fitting an appropriate lever k to the arms m<1>, m<1x> or m<2>, m<2x> and an appropriate disc j. Instead of the sliding lock bolt m a pivoted bolt or vertically sliding bolt or the two combined may be used.

Patent GB-1012828-A (GB)
Title: Process for producing elastic fabrics
IPC: D02G1/18
Filed: 1964-05-26
Abstract: Elastic fabric is produced by stretching an elastic yarn containing segmented polyurethane (spandix) continuous filaments and/or staple fibres by a constant or varying amount which may approach the elastic limit of the yarn, temporarily heat-selling the yarn e.g. by means of boiling water or steam to such a degree that on subsequent boiling it contracts by 30-60%, plying it with an inelastic yarn while maintaining the elastic yarn in fully extended condition, incorporating the plied yarn in a fabric e.g. by weaving or knitting, while maintaining it fully extended, and heat-relaxing the fabric to permit the elastic yarn to contract. The elastic yarn may comprise both the elastic fibres and inelastic natural or manmade fibres e.g. cotton, wool, silk, polyacrylies, polyamides, polyesters, cellulose derivatives or a blend of two or more thereof, and such latter continuous filaments or staple fibres may constitute the inelastic yarn. Examples of elastic yarns include a composite core-spun yarn i.e. a continuous filament elastic core yarn combined with one or more rovings of inelastic staple fibres, and a blended yarn of elastic and inelastic staple fibres.  Constituent yarns may differ in denier, amount and direction of twist, construction and/or fibre composition.  Plying is effected before or after the elastic yarn is heat-set.  Yarns having different retractive properties may be used e.g. in alternate picks or in warp only, to produce ridgid or seersucker surface effects.  Specifications 796,041, 796,044, 849,154, 849,156, 870,292, 893,758, 910,543, 916,287, 979,189 and 997,291 are referred to.

Abstract: 1,033,809. Producing polyester monofilaments. TEIJEN Ltd. May 31, 1963 [June 7, 1962], No. 21983/63. Heading B5B. A process for producing monofilaments derived from dibasic acids and dihydric alcohols, the dibasic acid component consisting of at least 50 mol. per cent of terephthalic acid, comprises melt extruding the polyester in the form of a filament, passing the extruded filament through an air gap, and then passing it into a bath of an inert quenching liquid which is maintained at a temperature not more than 5‹ C. below and not more than 50‹ C. above the second order transition point of the polyester. The polyester may be polyethylene terephthalate, and the temperature of the bath in this case should not exceed 120‹ C. The quenched and solidified monofilament may be stretched. The monofilament may have a substantially circular cross-section. The method is particularly well adapted for the production of polyester filaments of denier above 500 having a substantially circular cross-section. The distance through which the extruded monofilament travels through the air gap before entering the quenching bath is such that the filament is still liquid, or is not completely solidified, when it enters the quenching bath. The dibasic acid component of the polyester is preferably at least 75-100 mol. per cent terephthalic acid. If another dibasic acid is used, it may be phthalic acid, isophthalic acid, oxalic acid, adipic sebacic acid, suberic acid, glutaric acid, pimelic acid, fumaric acid or succinic acid. The polyester may be derived from a polymethylene glycol having 2-10 carbon atoms.
