Abstract: 1,126,855. Modified acrylic resins and graft polymers. HONNY KASEI K.K. (Honny Chemicals Co. Ltd.). 1 March, 1966, No. 9041/66. Headings C3G and C3P. [Also in Division C7] Aqueous solutions of water-soluble thermosetting resin compositions which may include pigments or water-soluble dyes and are suitable for producing coatings by electrodeposition, the coatings being cured by heating, are produced as follows:- (a) A mixture of methacrylic acid, ethyl acrylate, methyl methacrylate and styrene with benzoyl peroxide as catalyst and dodecyl mercaptan as regulator, together with methylol acrylamide is added in five portions to a mixture of ethylene glycol monobutyl ether and methanol and refluxed. After cooling the acid values are neutralized with aqueous ammonia and the product diluted with water. (b) A mixture of ethyl acrylate, methyl methacrylate, acrylic acid, butyl acrylate and hydroxyethyl acrylate together with benzoyl peroxide and dodecyl mercaptan is similarly reacted and neutralization is effected with triethylamine. The resulting solution is reacted by heating with a water-soluble melamine resin derived from hexamethylol melamine hexaalkyl ether. (c) An alkyd resin is formed from phthalic anhydride, safflower oil and glycerol. A graft polymer is then produced by adding to a solution of this alkyd resin a mixture of ethyl acrylate, methylol acrylamide, methacrylic acid, 2-hydroxyethyl acrylate, methyl methacrylate and styrene, together with benzoyl peroxide, and heating. The contents of the reactor are then cooled and neutralized with diethylamine. A similar graft polymerization is described in Examples 6 and 7.

Title: A process for preparing urea and quaternary ammonium salt mixtures
IPC: D06M13/432
Filed: 1963-03-11
Abstract: Solid mixtures of urea and a quaternary ammonium compound having at least one aliphatic C8 group, especially a C8 to C22 hydrocarbon and two alkyl groups each having a C1 to C20 chains together with a further C1 to C4 alkyl, or arylalkyl, alkylaryl, aryl, alicyclic or heterocyclic group, wherein one of the four groups constituting the quaternary ammonium group may carry a further quaternary ammonium group, are made by mixing the quaternary ammonium compound, optionally as a solution, to a melt or a solution, especially aqueous, of urea and recovering the solid mixture from said melt or solution, e.g. by evaporation, and preferably converting the dry melt into a particulate or prill form. 5 to 20% of quaternary per weight of urea is the preferred amount. In the embodiment an aqueous alcoholic solution of the quaternary, as obtained may be fed to the final urea concentration in a typical urea synthesis plant stream which thereafter is fed to prilling equipment.  The resulting prills may subsequently be tabulated. Examples of typical mono quaternaries include N-fatty dimethyl ammonium e.g. halides, N,N-di fatty dimethyl ammonium e.g. methosulphates, N,N,N,-trifatty methyl ammonium e.g. nitrites, N-fatty methyl benzyl ammonium e.g. sulphates, N,N-difatty methyl allyl benzyl ammonium e.g. chlorides, N-fatty dimethyl furfuryl ammonium chlorides. Examples of diquaternaries are also given.ALSO:Biocidal, e.g. bacteriocidal compositions, made by a novel process (see Division C2) comprise a solid mixture of urea and a quaternary ammonium compound of the general formula <FORM:0977099/A5-A6/1> where R1 is a C8 to C22 aliphatic hydrocarbon group, R2, R3 are each a C1 to C22 alkyl group and R4 is a C1 to C4 alkyl group, aralkyl, alkaryl, aryl groups or an alicyclic or hetero cyclic group, and one of R1 to R4 may carry a further quaternary amino group, and X- as a mono or polyvalent anion.  The composition preferably contains 5 to 20% by weight of quaternary based on the weight of urea and may be hard, dry, free-flowing particulate or prill form.  Specific quaternary ammonium ions are exemplified together with halide, sulphate, nitrite, nitrate, metho or ethosulphate radicles.  Other ingredients may be incorporated for specific end use of the products.

Title: Improvements in or relating to the processing of cellulosic textiles for imparting abrasion resistance and wash and wear characteristics
Inventor: DESAI RAMANLAL MARKANDRAI
IPC: D06M13/11
Filed: 1964-03-06
Abstract: Threads, yarns, nets and woven or knitted fabrics made from natural or regenerated cellulose-fibres, e.g. cotton or rayon, are crease proofed and their abrasion resistance is improved by p  reacting them with one or more aliphatic or aromatic acid esters of a 1:3-dihalopropanol-2 in the presence of an alkaline catalyst, e.g. sodium or potassium hydroxide.  The dihalo propanol ester may have the formula:  <FORM:1060902/D1-D2/1> in which X is a chlorine, bromine, iodine or fluorine atom and R is an aliphatic or aromatic acyl radical containing 2 to 30 carbon atoms.  Specified esters are the acetyl, propionyl, butyryl, lauroyl, myristoyl, stearoyl, benzoyl, salicyl and napthoyl esters.  The materials may also be treated with a 1:3-dihalo propanol-2.  The material may be treated with a solvent solution or aqueous-emulsion of the ester, squeezed to remove excess and then treated with an aqueous solution of the alkaline catalyst or it may first be treated with caustic soda solution to form soda cellulose, squeezed to remove excess caustic soda solution and then treated with a solvent solution or aqueous emulsion of the ester.  Alternatively the material may be treated with a solvent solution or aqueous emulsion of the ester, dried, impregnated with caustic soda solution, wrapped in a polythene sheet and kept with or without pressure for up to 24 hours.  The materials may subsequently be subjected to a second treatment with one of the esters or a 1:3-dihalo propanol-2 or a resin.  Suitable solvents for the esters are benzene, acetone, carbon tetrachloride, diethanolamine, chloroform and ethylene dichloride.  The process may be carried out at a temperature of 0-60 DEG C. 0.5-50% by weight of ester being applied.  10-40% by weight aqueous solutions of caustic alkali may be utilized.

Title: Improvements in mechanisms for feeding record and duplicating materials in manifolding machines

IPC: B41L1/00
Filed: 1960-03-18
Abstract: 945,612. Typewriters &c. ALACRA Ltd. March 16, 1961 [March 18, 1960], No. 9753/60. Heading B6F. In a typewriter or like machine wherein superposed webs of record material frictionally draw the interleaved carbon webs forward but at a slower speed, and a carbon-release mechanism is provided for controlling the carbon feed, a pin-wheel 411a or pin-band at one or each edge of the record material serves both to feed the material to and away from the platen 20, and guide means are provided which separate the record webs over a part of their travel from the pin-feed to the platen or from the platen to the pin-feed or both, so that the separated record webs travel along paths which are substantially of equal length and the divergence as they pass around the platen is reduced. As shown, the record webs 23 are separated after leaving the platen 20, by passing the innermost web over the lowest one of a series of rollers or bars 404 arranged in a plane tangential to the platen, the other webs 23 passing singly over the successive rollers 404. The webs then pass horizontally to and under a second series of rollers or bars 405 arranged in a plane parallel to the plane of the rollers 404 and tangential to the pin-wheel 411a. The carbon webs 22a pass diagonally from a roller 404 to a roller 405 as shown, and the reassembled webs pass from the top roller 405 to the pin-wheel 411a. The rollers 405 are mounted on a frame so as to be movable into the dotted-line positions adjacent to the rollers 404 to facilitate loading of the strips in the machine. The angle through which each web is turned by a pair of rollers 404, 405 can be otherwise than 90 degrees and the planes of the two sets of rollers need not be parallel, but the paths of the webs are such that their total lengths are substantially equal. Two adjustablyspaced edge-engaging channels 421 flared at their ends 423 may be provided in advance of the platen so as to cause any looseness in the webs to appear beyond the platen at B thus preventing misalignment. The channels may be moved away from the pin-wheel 411a during loading by cam means 425. A bar 406, Fig. 1 (not shown), may be provided on the infeed side of the pin-wheel 411a and moved close to the wheel to assist in engaging the pins in the perforations of the stationery during loading. The shaft 411 of the pin-wheel 411a is driven from and adjustable with respect to the platen. The pins on the wheel 411a may be projected only at the stationery-engaging positions by mechanism as described in Specification 408,125. Specifications 634,692, 848,797, 885,688, 886,254, 941,881 and 945,611 also are referred to.
