Abstract: Acetate rayon and polyamide fibres are dyed with dyestuffs of the formula:- <FORM:0758462/IV(c)/1> <FORM:0758462/IV(c)/2> where R i H, alkyl, or, in the case of polyamide fibres only, cycloalkyl, or hydrocycloalkyl, R1 is OH, NH2, NH-alkyl, N-(alkyl)2 or O-alkyl, or in the case of polyamide fibres only, -NHCO-alkyl, and X is H orOH. The dyeing is carried out in known manner, e.g. from an aqueous dispersion.  The dyes are made by condensing a substituted cyclohexylamine of the formula:- <FORM:0758462/IV(c)/3> with 1-amino, to 1-alkylamino, 1-cycloalkylamino, or 1-hydroxycycloalkylamino anthraquinones carrying exchangeable substituents in 4-position, or with anthraquinones carrying two exchangeable substituents in 1- and 4- position, or with leuco compounds thereof.

Title: Preparation of urea-dialdehyde starch derivatives
IPC: C08B31/18
Filed: 1959-09-28
Abstract: Mono- and di-urea oxystarch addition compounds are obtained by reacting at a temperature of from 20 DEG -70 DEG C. for 1-24 hours, urea with 2, 3-dialdehyde starch in the presence of water, acetone or a lower alcohol, the urea being dissolved, and the 2, 3-dialdehyde starch being slurried in said medium, and recovering the desired product by direct filtration from the reaction mixture.  The dialdehyde starch may be prepared by the electrolytic method of U.S.A. Specification 2,713,553 or by the oxidation of starch with periodic acid.  The mono-urea compound is obtained in 100% yield by reacting equimolecular proportions of urea and oxystarch in methanol at room temperature for about 16 hours, or at elevated temperatures for about 1 hour.  The diurea compound is produced by reacting two mols of urea with one of oxystarch polymer in the presence of 1%-8% of sulphuric acid for 1-3 hours at 30 DEG -70 DEG C. The compounds may be used as moulding powders, in the textile industry for yielding crease and crush-proof fabrics and in the adhesive and laminating industries.

Abstract: 1,159,242. Opening fibres; break spinning. VYZKUMNY USTAV BAVLNARSKY. 22 July, 1966 [19 March, 1966], No. 32974/66. Headings D1D and DIN. A device for separating textile fibres from a fibrous body e.g. a sliver 29 particularly preparatory to feeding the fibres to the chamber 24 of a break spinning device comprises a rotary comb 3, fed by means such as a roller pair 9, 10 which grips and feeds the fibrous body, the distance between gripping point of the feed device and the area A where the fibres are strongly worked by comb 3, being adjustable; the distance is preferably less than the staple length of the sliver fibres. As shown the adjustment is effected by moving a member 13 on which rollers 9, 10 are mounted. A channel 6 is provided in the body portion 1 of the device so that the fibres are carried to chamber 24 by the air currents it generates. In Fig. 3, not shown, rollers 9, 10 are provided with engaging elastic belts extending towards comb 3 and running around reversing elements. In Fig. 5, not shown, the feeding means comprises a feed roll (33) co-operating with a nose (38) on a removably mounted insert (39) which also provides the curving wall portion converging on the comb equivalent to wall portion 8 in Fig. 1. To adjust the distance between feed roller (33) and area (A), the feed roller is moved about the circumference of comb 3 by rotation of its supporting bracket (36) and insert (39) is replaced to ensure that nose portion (38) remains closely adjacent the feed roller.

Title: Method of increasing the size of the dispersed particles in a synthetic rubber latex
IPC: C08F36/04
Filed: 1959-09-29
Abstract: Dispersed polymer particles in a butadiene polymer synthetic rubber latex containing 2 to 10 parts of a water soluble soap of a soap-forming mono-carboxylic acid and having a pH from 8 to 11 are increased in size by reducing the pH to 55 to 75 in the presence of 0,05 to 1% of polyvinyl alcohol or polyethylene polyamine based on the solids weight and then increasing the pH to 8 to 11. The latex may then be concentrated e.g. from a solids content of 25 to 50% to one of 55 to 70%.  Specified polymers are those of butadiene, 2-methylbutadiene, 2, 3-dimethyl butadiene, piperylene, and their copolymers, with styrene, substituted styrenes, vinyl naphthaline, acrylic acid, methyl acrylate or methacrylate, acrylonitrile, methacrylonitrile, methacrylamide, vinyl pyridines, methyl vinyl ketone and vinylidene chloride.  Specified soaps are, the alkali metal, ammonium and amine salts of higher fatty acids having 10 to 24 carbon atoms in the molecule or of rosin acids including dehydrogenated, hydrogenated and disproportionated rosin acids. Other types of surface active dispersing agents may also be present. The pH is reduced with anidic material, e.g. carbon dioxide, formic acid, acetic acid, sodium silicofluoride, and ammonium and formaldehyde.  The pH is increased by the addition of ammonia or sodium or potassium hydroxide.

A composition may be formed from (A) the alkylolated polyurethane and (B) 0 to 1 mole per reactive tertiary amine group in (A) of a water-soluble inorganic acid or organic acid containing 1 to 4 carbon atoms, (C) 0 to 20% by weight of (A) of a surfactant, (D) 0 to 1 mole per reactive H atom present in (A) of an epoxide having at least 8 carbon atoms, (E) 0 to 1 mole per reactive alkylol group in (A) of a crosslinking agent, (F) 0 to 40% by weight of (A) of a pigment, and (G) 0 to 99% by weight of (A) of a solvent. The polyisocyanate (i) and those used to form the prepolymer (ii) are those aliphatic, cycloaliphatic and aromatic polyisocyanates conventionally used in the art. Linear and branched polyethers and polyesters may be used to form the prepolymer and as the reactant (c) when used. The reaction between the organic polyisocyanate or prepolymer and hydroxy ethyl carbamate may take place in the presence of a solvent and a catalyst. Alkylolation is effected by reacting the aldehyde or aldehyde liberating composition with the resin at 5 to 110 C. optionally in the presence of a solvent such as water, methanol, ethanol, butanol and xylene. In specific examples wood-to-wood bonds are produced from various compositions containing the alkylolated polurethanes after curing at room temperature.

In order to ensure that the filament of an incandescent lamp or the electrodes of a discharge lamp are accurately located with respect to the cap, the lamp has a glass base member forming part of the lamp envelope through which the leading-in conductors extend so as at least partly to support the filament or electrodes, at least one further member unconnected internally of the envelope to the filament or electrodes but accurately positioned relatively thereto being provided which frictionally engages and secures the cap to the envelope so that the filament or electrode is accurately positioned with respect to the cap. In the form shown, the envelope 1 of a projection lamp is sealed to a glass base 4 through which pass leading-in conductors 7 and one or more stub leads 13 which engage eyelets 14 in the cap 3. The filament 2 is of flat form consisting of a series of flat sections supported by arms 8 sealed into glass, beads 9, the beads being mounted on frame members 5 connected to the leading-in conductors 7 and to the ends 6 of the filament. The stub leads 13 may be secured in the eyelets by soldering.

Convention dates, Nov. 24, 1933 and Dec. 30, 1933. [Class 23] A centrifugal separator has collecting vessels 5, 6 for the separated liquids arranged above the bowl 1, and a collecting device consisting of a tube 4 for the overflow liquid. The tube leads to a funnel 7 and liquid from the funnel passes through the pipe 8 into the vessel 5. The pipe 8 is placed low down in the vessel so that it always contains liquid to prevent the escape of gas from the vessel. The tube 4 has a hinged door 9 which opens when liquid flows through the tube. In a modification a funnel 13, Fig. 2, is arranged in the discharge spout 14 of the vessel 5, and the tube 12 carries the overflow liquid from the annular basin 11 which receives it from the bowl. A liquid seal is provided between the funnel and the spout, and the tube 12 may be provided with a faucet 15 as shown on the right-hand side of Fig. 2. In another modification the overflow liquid flows through a channel into a small sight chamber from which it passes to a collecting chamber which also receives liquid from the chamber 5. In a further modification, the overflow liquid flows through the channels 16, 24, Fig. 5, to the chamber 19, and separated liquid flows through the channel 20. A sight glass 27 is provided in the door 26 of the chamber so that both liquids can be observed. Tubes may be added to extend the channels 20, 24.
