Title: Improvements in the colouring of cellulose triacetate textile materials
Inventor: OLPIN HENRY CHARLES
IPC: D06P3/50
Filed: 1956-11-27
Abstract: Cellulose triacetate textile material is coloured by applying a diazotizable base, diazotizing the base on the material, and coupling the resulting diazo compound with 2 : 3-hydroxynaphthoic acid, applied as an aqueous bath subsequently to the diazotization step, coupling being effected while the material is in a water-swollen state.  The diazotizable base may be a 4 : 41-diaminoazobenzene, especially 4 : 41-diamino-21 : 51-dimethoxyazobenzene, or may be 4 : 41-diamino-1 : 11-benzene-azo-naphthalene. Preferably the material is water-swollen by treatment with water together with a water-miscible softening agent for the cellulose triacetate.  The softening agent may be added to the aqueous bath of diazotizable base, or to the diazotization or coupling baths, but in the preferred method the material is impregnated with an aqueous solution of the softening agent, introduced into the bath containing the diazotizable base, the base is diazotized on the swollen material in a second aqueous bath and the resulting diazo compound is coupled with 2 : 3-hydroxynaphthoic acid in a third aqueous bath which may also contain a wetting agent.  The softening agent may be acetic or formic acid, or a water-miscible alcohol, ketone or ester, e.g. methyl, ethyl, n- or isopropyl alcohol, acetone, diacetone alcohol, or ethyl lactate, but is preferably a water-miscible ether, carboxylic ester, or ether carboxylic ester of a polyhydric alcohol, e.g. a C1-C3 fatty acid ester of diethylene glycol or glycerol, e.g. diethylene glycol mono-acetate or di-acetate, glycerol mono-, di-, or tri-acetate, a C1-C4 alkyl ether -C1-C3 fatty acid ester of a polyhydric alcohol, e.g. diethylene glycol mono-ethyl ether acetate, diethylene glycol monobutyl ether acetate, ethylene glycol monomethyl ether acetate, ethylene glycol monoethyl ether acetate, or a C1-C4 mono-alkyl ether of ethylene glycol, e.g. ethylene glycol monomethyl ether or ethylene glycol monoethyl ether.  Diethylene glycol diacetate is preferred. By the process of the invention dyeings are obtained in full shades which are resistant to steam treatment and to "bleeding off" on soap-scouring. Specifications 500,960, 758,442, 792,838, 813,611, 845,752, 850,365 and 859,685 are referred to.

Abstract: 1,004,208. Cable connectors. ANDERSON ELECTRIC CORPORATION. Sept. 20, 1963 [Dec. 21, 1962], No. 37056/63. Heading H2E. A cable connector comprises a malleable body with a generally U-shaped cable groove 15, Fig. 3, defined by a base 11 and sides 13 with recesses 23 at the junctures of the sides and the base; these recesses and the outer surfaces of the sides adjacent their free outer ends being adapted to receive the dies of a four-way crimping tool D1, D1A, D2, D2A so that upon inward movement of the dies a cruciform shaped crimped connection of the cable C and connector is formed (Fig. 5). Fig. 1 shows an L-shaped connector with similar legs 3 and 7 for making a branch connection to cable TC, the sides 13 having slots 27 which divide each side into two crimping sections which are individually crimped. The body is formed of a material which is not only malleable but has high electrical conductivity such as aluminium or aluminium alloy. The span of recesses 23 is less than the distance from the recesses to the free outer ends of the sides 13, and the sides taper as shown. A step 33 may be formed in the cable groove 31 to prevent deformation along the longitudinal axis during crimping. In a further embodiment (Figs. 8-10, not shown), the connector is T-shaped for connecting three cables together, and separate recesses are provided for each crimping section so that the dies may be accurately aligned. In a further embodiment (Figs. 11-12, not shown) the connector is adapted to crimp-connect a pair of parallel cables within the cable groove, the sides of which merge slightly instead of being substantially parallel, thus one pair of dies contact the sides of the groove before the other pair is seated within the recesses. In a further embodiment (Figs. 13-14, not shown), the connector has a pair of U-shaped cable grooves arranged in parallel offset relation to each other for connecting cables of large diameter.

Title: Process for the preparation of polymers of unsaturated aldehydes by radiation
IPC: C08G2/00
Filed: 1961-10-19
Abstract: Ethylenically unsaturated aldehydes are polymerized by exposing them to high-energy ionizing radiation in an acidic aqueous medium. Aldehydes specified are acrolein, methacrolein and alpha-ethyl, alpha-butyl, alpha-decyl, alpha-cyclohexyl, alpha-chloro and beta-phenyl acroleins. The aldehyde may be homopolymerized or it may be copolymerized with monomers such as dienes, ethylene, propylene, styrene, alpha-methylstyrene, vinyl pyridine and pyrrolidone, alkyl alcohol and its esters, vinyl acetate, vinyl halides, and acrylic and methacrylic acids, nitriles and esters, e.g. methyl acrylate.  The ionizing radiation used may be in the form of high energy electrons, protons or neutrons, gamma rays or X-rays.  The aqueous medium may contain an anti-coalescent, e.g. long chain sulphates and sulphonates, soaps, long chain basic nitrogenous compounds, and non-ionic emulsifiers of various types, including polymers. The resulting polymers are reactive with aqueous sulphur dioxide and alkali metal bisulphites to yield water-soluble products, which may be reacted with alkali to form polyhydroxy polycarboxylic acids or salts.ALSO:The properties of papers, e.g. wet strength, are improved by treatment with a bisulphite- or sulphur dioxide-solubilized polymer of an unsaturated aldehyde, which has been prepared by polymerization in an acid aqueous medium under the influence of high-energy ionizing radiation.  The polymer may be applied at the beater stage, or as an after-treatment for the paper.  The preferred polymer is polyacrolein.  Examples (1) and (2) describe the application of aqueous solutions of SO2-polyacrolein to sheets of bleached sulphite paper.

Abstract: 922,447. Cleaning spinning-machines. PARKS-CRAMER CO. Oct. 23, 1961 [Oct. 26, 1960], No. 37846/61. Class 120 (3). Travelling suction cleaning apparatus for textile machines comprises a blower having at least one inlet through which lint and dust are transferred to a normally closed collection chamber. When the chamber is opened for the discharge of accumulated lint &c. therefrom by the air stream directed therethrough by the blower, a normally closed auxiliary air inlet in the chamber also opens in order to increase the volume of air passing through the chamber. The cleaner 10 shown in Fig. 1 comprises a suction casing 11, communicating with ducts 14, 16, tubes 18 and nozzles 20, and a blower casing 12 housing an air impeller 13 and communicating through an outlet 22 with a collection chamber 24. The casings and chamber are supported and the impeller driven by an electric motor serving as a self-propelled carriage 26 with rollers or wheels 28 riding on tracks 30, 32. The chamber is closed by a hinged, foraminous door 38 and a pivoted auxiliary door 118 sealing an inlet opening 124. Both doors automatically open, and a shield 40 may be positioned to obstruct a filter 39, when the end of the chamber is opposite a waste receptacle 41. In the operation of a mechanism for opening and closing the doors, Figs. 1, 2 and 3, engagement of an abutment arm e.g. 86, with an adjustable, retractable trip finger 92, as the cleaner is travelling in the direction of the arrows, rotates a starwheel 72 one quarter of a revolution to the position shown and thereby moves the high point of an elliptical cam 64 from engagement with follower rollers 60 and allows a spring 52 to expand and shift a rod 48 to rotate a bell crank 46 and cause a link 42 to open door 38. The rotation of cam 64 also moves followers 103 to swing an arm 104 about pivot 105 and pull on cables 112 to open door 118 against the constraint of springs, Fig. 4 (not shown). As the cleaner continues its movement, an abutment arm 74 engages a trip finger 90 and causes rotation of cam 64 through one quarter turn so that it exerts control on followers 60 and releases followers 103 to close the doors. In the operation of another mechanism, Fig. 5, a follower 126 engages a cam 125 and pivots a lever 127 to move a link 132 which operates a crank arm 134 to rotate a shaft 136. A crank arm on shaft 136 moves link 142 against the action of springs, Fig. 6 (not shown), to open door 38 and another crank arm 144 moves a link 146 to open spring- loaded door 118. Disengagement of cam 125 and follower 126 allows the springs to rotate shaft 136 and close the doors. Specification 852,763 is referred to.
