Title: Improvements in or relating to straight bar knitting machines
Inventor: BLOOD RAYMOND
IPC: D04B11/00
Filed: 1958-07-18
Abstract: 925,592. Knitting-machines. WILLIAM COTTON Ltd. July 13,1959 [July 18, 1958], No. 23056/58. Class 74 (2). During running of a straight bar machine, a machine part, e.g. selvedge stops 14, 15, is intermittently adjusted in opposite directions from a starting position, when starting a blank, to a finishing position, when finishing the blank, and, when the blank is finished and the machine is stopped, a reversible power drive, e.g. a reversible electric motor 20, is operated, under the control of means influenced by the different directional movement of this part from one side to the other of the starting position, to reset the part in the starting position with a continuous motion. Draw screw nuts 7a, 7b are similarly intermittently adjusted; and they are reset with the selvedge stops by the motor. In the arrangement of Fig. 1, the usual racking means effects the intermittent adjustment of the selvedge stops and, through chain and sprocket control means 12, similar adjustment of the draw screw nuts. In a modification, the sprocket-wheel 43 on the shaft 10 is loose thereon and is connected thereto by a clutch having coacting teeth 45a, 43b -which are widely spaced to provide lost motion during which the selvedge stops can be adjusted by their racking means. During this adjustment, rotation of the sprocket-wheel 43 causes traversing of a nut 46 along a screw-threaded bush 43a of the wheel and consequent operation of two-way switch means 47, 48, 49, to cause the motor 20 to provide follow-up adjustment of the draw nuts. The control circuit, Fig. 5 and Fig. 8 (not shown), includes switch means ensuring that the resetting and follow-up operations of the motor can only take place when the machine is stationary, and running, respectively. A switch 28 associated with a re-set stop 18a and coacting with a screw 32 on the selvedge stop 14, determines the appropriate direction of rotation of the motor; a switch 33 also associated with the reset stop and coacting with a cam-plate 34 on the stop 14 determines the stage at which electro-magnetic clutches 24a, 26a shall be operated to change over from a high speed drive 26 to a low speed drive 24; a switch 35, also associated with stop 18a and operated by a screw 36 on stop 14, prepares the circuit for stopping; and a final stop switch 37 is operated by a screw 40 on the plunger 39 of an index wheel. Further switch means ensures that the operation of the motor for follow-up adjustment of the draw nuts shall occur when the variable draw is in its position of minimum load, the mid position.

Title: Improvements in leather substitutes
Inventor: GRAHAM BOYNTON
IPC: D04H1/4382
Filed: 1955-08-12
Abstract: 782,952. Agglutinated fibrous sheet materials. DU PONT DE NEMOURS & CO., E. I. Aug. 12, 1955, No. 23350/55. Class 140. A leather-like product comprises, by weight, 40 to 85 per cent of matted oriented fibres of a synthetic linear condensation polymer and, distributed therethrough, 60 to 15 per cent of a polymeric binder, chemically dissimilar to the said linear condensation, polymer, incompatible therewith and melting below the softening temperature thereof, the said product containing a volume per cent of interconnecting void space distributed therethrough at least equal to 3000 (weight per cent fibre)<SP>-1</SP>-30 and not greater than 70 per cent. The product may be prepared by mixing the fibres with the binder and then partially consolidating the mixture under controlled conditions of temperature and pressure. Mixing may be carried out by impregnating a porous non-woven mat, web, or felt of the fibres with a solution or dispersion of the binder or, where fibrous or particulate forms of the binder are used, by mixing such as is achieved in conventional carding procedures. The mat, prior to impregnation with the binder should have a bulk density of less than 0.5 g/cc. Mats may be formed by paper-making techniques, carding or deposition from an air stream. Specified polymers for use as the fibre component are dibasic acid/diamine or amino acid polyamides, the dibasic acid/diol or hydroxy acid polyesters or the intermixed polyester/polyamide products or mixtures thereof; such as polytetramethylenesebacamide, polyethyleneterephthalamide, poly-D-, or L-, or DL-alanine, poly-D, or L-, or DL-leucine, and polyepsilon-amino-caproic acid, polydodecamethylene adipate, polyethylene sebacate, polyhexamethylene oxalate, poly-D-, or L-, or DL-lactic acid, poly-D- or L-, or DL- mandelic acid and poly-epsilon-hydroxy-caproic acid. Structural fibres ranging in length from 0.01 inch to 8 inches may be used. Specified polymers for use as the binder are cellulose acetate, cyanoethyl cellulose, polyethylene, polypropylene, polyisobutylene, polybutene-2, polyisoprene, vinyl chloride, 2-3-dichlorobutadiene, vinyl acetate, butadiene (styrene, tetrafluoroethylene/ethylene, vinyl chloride/vinyl acetate and vinylidene polymers and copolymers including both the monoene and diene types. The fibre-binder ratio may vary, on a weight basis, from 40/60 to 85/15. In an example 2 mats of polyhexamethyleneadipamide fibres are impregnated with a dispersion of polyvinyl chloride/di-2-ethylhexyl phthalate in a tetrahydrofuran/dimethyl formamide solvent mixture, dried, plied together and then pressed for 10 minutes at 160 C.

Title: Production of substituted arylamino acridine derivatives
IPC: C07D219/10
Filed: 1944-11-24
Abstract: Arylamino acridine derivatives having the general formula <FORM:0604279/IV(b)/1> in which R represents hydrogen or an alkyl, aryl or aralkyl group and n represents an integer not greater than 8 are obtained by heating a meso-halogenated acridine with a primary or secondary arylamine of the general formula <FORM:0604279/IV(b)/2> in which R and n are as above defined.  The meso-halogenated acridines are advantageously meso-chloroacridines and may contain one or more nuclear substituents such as alkyl, alkoxy, nitro, amino, substituted amino, cyano or halogen in either or both of the benzenoid nuclei. Specified acridines are: 9-chloroacridine, 9-bromoacridine, 2-methoxy-9-chloroacridine, 2- and 3-cyano-9-chloro-acridines, 2-methoxy-6-cyano-9-chloro-acridine, 2-methoxy-7-cyano - 9 - chloro - acridine, 2 - methoxy - 6.9-dichloroacridine - 2 - methoxy - 6.9 - dibromoacridine and 2-dimethylamino-6.9-dichloroacridine.  The primary or secondary arylamine used has the residue -(CH2)n-CN in the p-position with respect to the amino group and there may be p present one or more additional nuclear substituents, viz. alkyl (e.g. methyl, ethyl and isopropyl), alkoxy (e.g. methoxy and ethoxy) and halogen substituents.  Specified arylamines are: a para-aminophenyl-acylonitrile, e.g. p-amino-benzyl cyanide; a mono-N-alkyl substituted p-aminophenyl-acylonitrile, e.g. an N-methyl-p-aminophenyl-acetonitrile, or an N-aryl or N-aralkyl-p-aminophenyl-acylonitrile.  Advantageously, the reaction takes place in an alkanol solution, the alkanol containing not more than eight carbon atoms, preferably anhydrous, and preferably in the presence of a small amount of copper powder. Alternatively, when R represents hydrogen the reactants may be heated in an excess of a phenol, e.g. phenol, the cresols, or higher alkylated phenols, the meso-halogenated acridine and phenol being first heated together and the product, with or without isolation, is then heated with the primary arylamine.  In examples: (1) 9-chloroacridine is dissolved in an excess of molten phenol and the solution treated with p-amino benzyl cyanide to obtain 9-(41-cyanomethylphenyl-amino)-acridine; (2) 2-methoxy-6 : 9-dichloroacridine is heated with an excess of phenol and the mixture is treated with p-amino benzyl cyanide to obtain 2-methoxy-6-chloro-9-(41-cyanomethyl phenylamino)-acridine.  The aminophenyl acylonitriles may be obtained by the reduction of the corresponding nitro compounds by known methods.
