Title: Improvements in the bleaching of viscose rayon yarns and filaments
Inventor: SPEIR ROBERT DAVIES
IPC: D06L4/70
Filed: 1958-06-03
Abstract: Viscose rayon filaments or yarns are bleached at a convenient stage between the extrusion bath and drying zone by subjecting them to successive separate treatments with (1) an aqueous acid solution, (2) an aqueous solution of an alkali metal permanganate and (3) an aqueous solution of hydrogen peroxide.  The acid employed in stage (1) is preferably sulphuric acid having a concentration of 11-13% by weight at a temperature of 60 DEG -80 DEG C. although acetic and phosphoric acids are also suitable.  Dilute aqueous sulphuric, acetic or phosphoric acid solutions of potassium permanganate and hydrogen peroxide may be used although, depending on the acid carried over from stage (1), aqueous solutions of potassium permanganate and hydrogen peroxide without the addition of acid may be used.  The filaments or yarns may be contacted with the permanganate for 1-20 seconds followed immediately by the application of the peroxide solution, the time of interaction of the permanganate and peroxide prior to washing the filament or yarn preferably being 10 seconds or less.  The treatments with permanganate and peroxide in stages (2) and (3) may be repeated one or more times, the material being treated with peroxide after each treatment with permanganate.  Specifications 620,440 and 826,190 are referred to.ALSO:Viscose rayon filaments and yarns are bleached by subjecting them to successive separate treatments with (1) an aqueous acid solution, (2) an aqueous solution of an alkali metal permanganate and (3) an aqueous solution of hydrogen peroxide.

Abstract: 1,216,454. Gas burners. KOHO-ES GEPIPARI MINISZTERIUM TUZELESTECHNIKAI KUTATOINTEZET. 8 April, 1969 [8 April, 1968], No. 17764/69. Heading F4T. Either a low or a high heat output may be obtained from a non-atmospheric gas burner by the operation of a solenoid 11 which adjusts both air and gas supplies to the burner by means of a conical air valve 12 co-operating with a valve seat 28 in an apertured partition 26 of the casing, and a valve needle 24 in a gas nozzle 20. In the high output position illustrated, a fan 9 driven by electric motor 1 conveys air past the valve cone 12 where the air is made more turbulent by helical grooves in a collar 31 on the cone, and a sping 27 holds the valve needle 24 in its open position against an adjustment screw 29. On de-energization of the solenoid 11, the cone and needle are moved by spring 14, reducing the gas flow and permitting air to flow only through apertures 22 in a less turbulent manner, maintaining the air-gas proportion and the length of flame substantially constant. An igniter 15 and flame detector 16 are also provided. The fuel may be natural gas.

IPC: D06B3/10
Filed: 1947-07-07
Abstract: <PICT:0631279/IV (c)/1> <PICT:0631279/IV (c)/2> In an apparatus for treating webs with fluid such as dyes, or gases, the web is fed through a covered chamber 10 in festoon form, and is advanced in such a manner as to avoid undue strain regardless of shrinkage or elongation of the web, and to avoid curling of the edges.  As applied to feeding a web 24 through a series of tanks, the web is passed over rolls 16, over guide rolls 26, and is finally fed out of the apparatus by an idler roll 22 and a roller 20 which is driven at a lower speed than the rolls 16.  The rolls 16 slip forwardly relatively to the advancing web and thus diminish strain on the web. The roller 20 is preferably geared to the driving means for the rolls 16.  The rolls 16 may be constructed as shown in Fig. 3 with battens 32, and right and left p  spiral wires 34 which spread the web laterally and prevent curling.  The webs are led over guide rollers 26 which may be braked by an adjustable friction device 28.  The rollers 16 may be replaced by rollers having inclined projections 40, Fig. 4, not shown, or by reels which are perforated, or formed of wire construction.

Abstract: A fibrous composition is made by mixing the sodium salt of one or more of polyacrylic acid, alginic acid and cellulose-glycollic acid with a latex of a rubber and with fibrous material, and then adding a water-soluble salt of a multivalent metal to coagulate the mixture. The rubber may be a styrene-butadiene copolymer, an acrylonitrile-butadiene copolymer, polychloroprene or natural rubber. The fibres may be a cellulosic pulp e.g. kraft pulp, sulphate pulp or regenerated cellulose, synthetic fibres such as polyvinyl alcohol, polyamide or polyester, leather scrap or asbestos.  The coagulant may be alum, sodium aliminate, zinc sulphate, magnesium chloride, calcium chloride or calcium nitrate.

Abstract: An oxide of a tertiary amine in which none of the residues linked to nitrogen contains more than six carbon atoms, but which contains a hydroxyl group, is treated with a reagent which is capable of reacting with a hydroxyl group and contains an aliphatic or hydroaromatic radicle of at least six carbon atoms. Suitable reagents are aliphatic or hydroaromatic carboxylic acids of high molecular weight or their halides, or higher alkyl halides.  An example is given in which diethylaminoethanol oxide (from diethylaminoethanol and hydrogen peroxide) is esterified in pyridine with lauric acid chloride.  Other specified oxides which may be treated are triethanolamine oxide, morpholine-ethanol oxide, oxyethylpiperidine oxide, oxyethylmethylcyclohexylamine oxide, and diethylaminopentanol oxide.  The products resemble those of the parent Specification and are useful as textile assistants.

Title: Hydraulic control device for two non simultaneous displacements

Abstract: 931,691. Milling. FABRIQUE DE MACHINES MIKRON S.A. May 14, 1962 [Sept. 1, 1961], No. 18533/62. Class 83 (3). [Also in Group XXIX] An hydraulic control device for two non- simultaneous displacements comprises two coaxial pistons 6, 7, each slidably mounted in a chamber 4, 5 of a cylinder 1, 2 and urged away from the other by an elastic device 20 between the pistons, the feeding of fluid under pressure to one of the chambers being controlled through the displacement of the piston sliding in the other chamber. The device may be applied to a machine tool having a cutter F carried on a lever 37 connected by a pivot 38 to a slide 39, the lever being rocked by a member 43 operated by the piston 6 and the slide being moved by the piston 7. The piston 6 is movable against the elastic device 20 by fluid pressure supplied to the chamber 4 from a pump 21 under the control of a valve 22 and a regulator 23, and during its movement causes a part 14 to engage the member 43 which is rocked about a pivot to displace a pin 43 engaging an adjustable pin 46 on the lever 37 to raise the cutter F. Towards the end of the movement of the piston 6, a land 17 uncovers a passage 28 to enable fluid from the pump to pass through a passage 25 into the passage 28 which has a regulating valve 29 controlling the flow to the chamber 5 so that the piston 7 moves against the elastic device, the piston being connected to the slide by an arm 41 secured to a threaded extension 8 of the piston. The extension 8 of the piston carries a ring 32 which is held in contact with springs 35 by an adjustable nut 34 and carries an arm 33 having an adjustable screw 36 co-operating with a microswitch M, operation of which stops the pump and reverses the valve 22 to permit the elastic device 20 to return the pistons to their original position. A one-way valve 11 prevents return flow through the passage 25 and prevents the piston 7 returning to its original position until after the fluid has been exhausted from chanber 4 and the land 17 permits fluid from chamber 5 and passage 28 to pass to an exhaust passage 31. One-way valves 27, 30 permit the flow from the chambers to by-pass the regulating valves 23, 29 and the pistons to rapidly return to their original positions. In an alternative embodiment, the piston 7 is not connected to a movable member and its movement serves to control the time the piston 6 is in its advanced position.
