Patent GB-1384645-A (GB)
Title: Method of crimping and texturing
IPC: D01D10/04
Filed: 1972-05-05
Abstract: 1384645 Crimping and texturing fibres TEXTILKOMBINAT COTTBUS VEB 5 May 1972 21064/72 Heading B5B Filaments are crimped and threads textured by modifying them intermittently over their length, and optionally also to a varying degree over their diameter or thickness, either by intermittent irradiation with electron beams or by uniform irradiation with electron beams and intermittent heat treatment before and/or during and/or after said irradiation so as to produce inhomogeneities which provide sites for crimping or texturing; self-crimping may take place, or, otherwise, the modified filaments or threads are thereafter crimped. Cross-linking or partial destruction of the filaments or threads intermittently over their length and optionally also to a varying degree over their diameter or thickness may be effected, as may similarly intermittent or varying radical formation, or the initiation of graft polymerization, suitably by controlling the position and/or intensity of the electron beam. Intermittent heat treatment, e.g. using laser beams or heated profiled rollers, may be used to effect intermittent radical formation, especially after homogeneous irradiation. In Fig. 1, a polyacrylonitrile sliver 1 is intermittently irradiated over the longitudinal axis of the filaments by the electron beams 2 under the scanner 3 of an electron accelerator 4, through a grid moving along the sliver. Acrylamide in vessel 6 is grafted on to the locally initiated parts of the filaments, the resulting anisotropy effecting crimping through differential shrinkage or drying in drier 7. Maleic acid may replace acrylamide. In Fig. 2, a fleece of polypropylene fibres 8 is irradiated by electron beams 2 and passes over a heated profiled roller 9 provided with cross-grooves. Due to the selective thermal treatment, intermittent degrees of cross-linking occur over the longitudinal axis of the fibres; thermal treatment in dyeing bath 11 causes selective shrinkage and produces self-crimping. Further examples relate to the electron beam irradiation of polyamide filaments followed by passage over a heated profiled roller and grafting with styrene, and the electron beam irradiation of polyacrylonitrile sliver, followed by laser beam treatment and grafting with acrylic acid.

Title: Improvements in the preparation of dichloroacet-4-hydroxy-n-methylanilide
Inventor: BRISTOW NORMAN WILLIAM
IPC: C07C231/00
Filed: 1955-07-22
Abstract: Dichloroacet - 4 - hydroxy - N - methylanilide is prepared by reacting 4 - hydroxy - N - methylaniline or a water-soluble salt thereof with chloral cyanhydrin in the presence of an acid-binding agent.  The chloral cyanhydrin may be prepared in situ, e.g. by reacting chloral hydrate with an alkali metal cyanide and an alkali metal bisulphite.  The molecular ratio of 4-hydroxy-N-methylaniline to chloral cyanhydrin is preferably at least 1 : 1, and when the former compound is in the form of the free base a part thereof may act as the acid-binding agent.  Other suitable acid-binding agents are tertiary alkyl amines and alkali metal hydroxides, carbonates and acetates, preferably in an amount of two equivalents per mol. of chloral cyanhydrin when using free 4-hydroxy-N-methylaniline and proportionately more when using a salt thereof, the reaction being advantageously performed in an organic solvent in the former case and in an aqueous medium in the latter case.  Examples describe the reaction of: (1) preformed chloral cyanhydrin, free 4-hydroxy-N-methylaniline and triethylamine in pyridine; (2) the same reactants in dioxan; (3) as in (1) except that triethylamine is replaced by aqueous caustic soda; (4) chloral cyanhydrin, 4-hydroxy-N-methylaniline sulphate and triethylamine in water containing a trace of sodium sulphite; (5) as in (4) except that triethylamine is replaced by aqueous caustic soda; (6) as in (4) except that triethylamine is replaced by an aqueous solution of sodium carbonate; (7) as in (5) but using a larger amount of sodium sulphite; (8) chloral hydrate, sodium bisulphite and sodium cyanide in water, and the resulting solution with 4 - hydroxy - N - methylaniline sulphate and caustic soda; (9) as in (8) except that caustic soda is replaced by sodium carbonate; (10) 4 - hydroxy - N - methylaniline, potassium cyanide, sodium sulphite and chloral hydrate in water; (11) as in (10) with the addition of sodium acetate; (12) and (13) as in (10) with the addition of calcium carbonate and reduction of the amount of potassium cyanide; (14) as in (10) with the addition of sodium carbonate; (15) 4 - hydroxy - N - methylaniline sulphate, sodium acetate, sodium sulphite, potassium cyanide and chloral hydrate in water; (16) as in (15) except that sodium acetate is replaced by sodium carbonate; (17) and (18) 4-hydroxy-N-methylaniline sulphate, sodium sulphite, caustic soda, sodium cyanide and chloral hydrate in water.

Patent GB-1060623-A (GB)
Title: Polyester filaments which can be dyed with dispersion dyestuffs, vat dyestuffs and acd dyestuffs
IPC: D01F6/62
Filed: 1964-05-25
Abstract: In a process for improving the dyeability of filaments or fibre tows made of or containing high molecular weight linear polyesters, which have not been heat-set, the filaments or tows are treated, prior to or after stretching, with a tertiary monoamine which carries at least one aliphatic radical having 6 to 20 carbon atoms and/or an aromatic radical on the nitrogen atom, or an ammonium compound derived therefrom, the filaments or tows are stretched if not already stretched, and dried if the amine or ammonium compound has been applied as a solution or emulsion and are than allowed to shrink by a determined amount at temperatures above 190 DEG C.  The amine may have the formula <FORM:1060623/D1-D2/1> where R is an aryl or aralkyl radical or an aliphatic radical having 6-20 carbon atoms, which may also contain an alcoholic hydroxyl group, an ester group or one or several ether group, and R2 and R3 are saturated aliphatic radicals having 1-20 carbon atoms, which may also contain an alcoholic hydroxyl group, an ester group or one or several ether groups, or are aliphatic radicals containing 1 to 3 carbon atoms.  R1 may be inter alia an alkylene glycol ether or polyalkylene glycol ether radical, the free hydroxyl groups of which may be etherified with an aliphatic alcohol, or esterified with a fatty acid.  R1 may also be a benzalkyl phenyl or diphenyl radical.  R2 or R3 may be inter alia an alkanol radical having 1-3 carbon atoms, an alkoxy radical, or a polyalkylene glycol ether radical. Many amines and ammonium compounds derived therefrom are exemplified, e.g. dimethyl aniline, and didodecyl-methylamine. The amine may be applied to the stretched or unstretched filaments in the pure state or in the form of an aqueous or non-aqueous solution or emulsion at room temperature or elevated temperatures up to 90 DEG C., by passing the filaments through a bath, or by spraying, or by use of rollers.  The amount of base on the filaments is preferably 0.5-1.5% of the weight of the polyester filaments.  Shrinkage may be carried out by passing the filament or tow through a heated zone between conveyers, e.g. rollers rotating to allow shrinkage of e.g. 10-50%.  The heating may be effected by hot air, heated liquid, e.g. metal, baths, infra-red radiation or heated plates.  The treated filaments are preferably restretched after shrinkage.  The treated polyester filaments may be dyed with acid, vat or dispersion dyestuffs, which may be added, if desired, to an aqueous solution or emulsion of amine with which the filaments are treated so that the dyestuff diffuses, together with the amine, into the filament.  Examples relate to the impregnation of polyethylene terephthalate filaments.

Abstract: 599,676. Fluid-pressure servomotorcontrol systems. BENDIX AVIATION CORPORATION. Dec. 25, 1943, No. 21694. Convention date, Oct. 31, 1942. [Class 135] In a clutch control mechanism for vehicles, the clutch (not shown) is operated through a shaft 14 by a servomotor 10 under control of the accelerator pedal 46 and an engine-operated governor 67 to give a two-stage engagement. In the first stage, the accelerator pedal, which is connected through a lost-motion slot 96 to the engine throttle lever 100, operates through a rod 54, spring 58, lever 48 and rod 42, a pistonvalve member 40, Fig. 2, within the hollow piston-rod 16 to control the engine suction acting on the piston 12 of the servomotor which '' follows-up " the movement of the valve to give an initial light engagement of the clutch. Further movement of the accelerator to open the throttle valve and speed up the engine does not operate valve 40 directly, owing to a stop 94 on a governor lever 82 limiting movement of lever 48, but governor 67 then comes into operation through levers 82 and 48 to operate valve 40 for full engagement of the clutch. A cut-out valve unit 32 is provided for the servomotor 10, which controls the conduit 30 from the induction manifold 26 and is electrically operated, being in circuit with an ignition switch 53 and a clutch control switch 55. Thus, when the ignition is switched on, valve 32 connects the servomotor to the suction conduit, but this connection may be broken by a switch 59 operated when the transmission is in high gear and/or a vehicle governor switch 57 operated at a sufficiently high speed of the vehicle. When these conditions exist the clutch must be operated manually.
