Patent GB-1304504-A (GB)
IPC: C08G69/36
Filed: 1971-04-27
Abstract: 1304504 Composite polyamide filaments E I DU PONT DE NEMOURS & CO 27 April 1971 [1 May 1970] 11684/71 Heading B5B A crimpable filament has two continuous adherent components, one component being a homopolyamide and the second component being a random copolyamide containing 70 to 82% by weight of hexamethylene adipamide units, 13 to 25% by weight of caproamide units and 5 to 17% by weight of hexamethylene dodecanedioamide units.  The homopolyamide may be polyhexamethylene adipamide, or polyepsilon caprolactam. The random copolyamide is preferably 75% by weight of hexamethylene adipamide units, 15% by weight of caproamide units and 10% by weight of hexamethylene dodecanedioamide units. Desirably, the random copolyamide has a differential thermal analysis melting point of 210 to 225‹ C., and an amide group frequency of 8,440 to 8,725 equivalents per 10<SP>6</SP> grams of polymer. The filaments are made by extruding the homopolyamide and copolyamide in either a side-by-side or a sheath-core relationship to form filaments, tensioning and drawing the filaments in conventional manner, passing the drawn filament through a heating zone under low tension to develop crimp and thereafter stretching the filament to remove crimp. In Examples, the filaments are melt-spun, quenched in air, and the wound-up filaments are subsequently drawn at draw ratios of 4À47 to 5À02 using an unheated drawpin. The filaments are then crimped, by passage through a tubular crimping chamber, using temperatures of at least 140‹ C. The filaments are subsequently heated to remove crimp, by passage through a hot air chamber, temperatures of 278‹ C. and 295‹ C. being used in the Examples. The yarn is then passed over a series of snubbing pins, then to a withdrawal roll and finally to a winding device. The snubbing pins act to reduce the speed of the yarn in the heating zone so that the components can shrink differentially and the filaments can crimp under the influence of the heat. In addition, the yarn is stretched sufficiently between the pins and the withdrawal roll to remove most of the crimp. Between the withdrawal and the withdrawal rolls, the yarn may be permitted to retract by 40% of its as-drawn length. When the crimpable yarn is exposed to hot water or steam, it crimps again in very uniform fashion, and the crimp diameter and crimp elongation are quite uniform. Filaments so made may have a crimp elongation of greater than 30%, a crimp diameter of less than 0À152 mm., a shrinkage of less than 4%, and an after boil-off tenacity of at least 4À0 grams per denier.

Title: Improvements in sheet separating mechanism
IPC: B65H3/08
Filed: 1945-05-10
Abstract: 591,433. Feeding sheets. HOE & CO., Ltd., R., and BATTEY, A. P. May 10, 1945, No. 11688. [Class 100 (i)] A device for separating sheets from a pile preparatory to feeding to printing or other machines comprises a suction device 1 mounted on a pivoted member 2 which can move around a pivot 4 and so bend a portion of the top sheet of a pile when pressure is lowered in a chamber 3 forming part of a foot attached to a tube 7 connected to a piston 8 capable of moving in a fixed double-ended cylinder 9. When air pressure is reduced in a vacuum line 11, pressure is reduced on the lower side of the piston 8 via an aperture 10, and the pressure on the upper side of the piston is maintained at atmosphere owing to the suction device 1 not being closed, although the upper part of the cylinder 9 is connected to the line 11 via an aperture 14. The tube 7 extends through the piston 8 to connect the upper part of cylinder 9 to the suction device 1. When the foot and suction device 1 engage the pile the reduction of pressure in the chamber 3, which occurs when the engagement of the device 1 with the pile cuts off the connection of tube 7 to the atmosphere, causes first the pivotal motion of the member 2 and consequent bending of the sheet as shown in Fig. 3, and also causes diminution of pressure on the upper part of the piston 8 through escape of air past an aperture 15 in the tube 7 above the piston. The tube 7 thus is raised owing to the differential pressure action on the piston 8. A valve member 19 may be used to control the aperture 15, the valve being attached by a rod 18 to the suction device, so that the action of the pivoted member 2 takes place quickly. To cause the raising action of the piston 8 to be slow at first an adjustable " bleed " aperture 16 controlled by a valve 17 is formed in the cylinder 9, and when the piston passes this aperture its motion is accelerated. The sucker assembly can be adjusted angularly so as to allow its line of action to be set diagonally, and the cylinder 9 can be given a motion parallel to the top of the pile to forward the separated sheet, and a locking device may prevent the forwarding action until the piston 8 has completed its upward movement.

Title: Improvements in and relating to the production of polymeric esters
IPC: C08G63/672
Filed: 1949-04-29
Abstract: Polymeric esters are produced by condensing (1) hydroquinone bis-(b -hydroxy-ethyl)-ether, or an acyl derivative thereof containing up to 4 carbon atoms in the acyl group with (2) an o ,o 1-dicarboxylic acid, e.g. succinic, adipic or sebacic acid, terephthalic acid, diphenyl-4,41-dicarboxylic acid or a dicarboxylic acid of the type <FORM:0651762/IV (a)/1> in which R is a bivalent group, e.g. -(CH2)-, or -O-(CH2)2-O-, or a diester of such dicarboxylic acids with a monohydric alcohol containing up to 4 carbon atoms. As a modification, a precondensation product of the above reactants is reacted further with a mixture of the dicarboxylic acid or its ester and a diester formed from an aliphatic monocarboxylic acid and an aromatic dihydroxy compound in which the hydroxy groups if on the same benzene nucleus are in the m or p positions with respect to each other and if on different benzene nuclei are in the p and p1 positions or in the m and m1 positions.  Such diesters may be, e.g., the diesters of hydroquinone or resorcinol, as described in Specification 636,429. In a further modification excess of the dicarboxylic acid or its ester is used in the precondensation and the aromatic ester is added for the further condensation.  The preparation of the diols is described (see Group VI (b)).  The reaction is preferably carried out by heating the mixture firstly at 200 DEG  C. in an inert atmosphere to drive off most of the by-product and then at 240-300 DEG  C. under reduced pressure, e.g. 0.1 to 0.5 mm. of mercury.  Suitable catalysts are lithium or sodium methoxide, aluminium ethoxide or paratoluene sulphonic acid. Examples describe the formation of polyesters capable of being drawn into fibres by heating in presence of catalysts mixtures of hydroquinone bis-(b -hydroxyethyl)-ether and (1) dimethyl terephthalate; (2) dimethyl succinate; (3) the compound <FORM:0651762/IV (a)/2> Other examples employ the diacetate of hydroquinone bis-(b -hydroxyethyl)-ether with (6) succinic acid, and (7) dimethyl terephthalate.  Mixed polyesters are prepared by (4) precondensing hydroquinone bis-(b -hydroxyethyl)-ether with sebacic acid, adding hydroquinone diacetate and more sebacic acid, and continuing the reaction; (5) a similar process to (4) using adipic in place of sebacic acid.  Specification 588,833, U.S.A. Specification 2,284,637 and French Specification 866,821 also are referred to. Reference has been directed by the Comptroller to Specification 678,264.ALSO:Hydroquinone bis-(b -hydroxyethyl)-ether is prepared by adding ethylene chlorhydrin to an aqueous alkaline solution of hydroquinone and heating the resulting solution.

Title: Improvements in or relating to the ringless spinning of textile fibres
IPC: D01H4/40
Filed: 1966-03-18
Abstract: In break-spinning to avoid uneveness in the degree of twist in the spun yarn, the inlet to the channel through which the yarn is withdrawn is situated at or near the axis about which the spinning chamber rotates, and the axis of the channel is directed in a straight line from the collecting surface to the delivery rollers. The spinning chamber is in the conventional form of two opposed frustoconical parts with a collecting-surface 4 when they join, and it is closed by a stationary solid body 10 in which the channel is formed by an oblique bore 8 which is substantially in line with the rotational axis and lies along a line which meets the wall of the chamber at the collecting-surface.  The fibres to be spun are fed in through a channel 3 in the body.  The spun yarn is withdrawn by delivery rollers 6 to be taken up on a bobbin.  As the chamber rotates, when the take-off point of the yarn is above the inlet of the channel, there is a difference in the degree of twist in the portion of yarn between the rollers and the inlet, compared with that of the portion in the channel.  This difference is neutralized by the twist running back to the portion in the chamber as the take-off point moves, as the chamber rotates, to a position in line with the inclined channel.
