IPC: C09B45/14
Filed: 1962-08-07
Abstract: The invention comprises azo dyes of the formula <FORM:1015788/C4-C5/1> wherein R1 represents hydrogen or a substituted or unsubstituted alkyl radical, R2 hydrogen or a substituted or unsubstituted alkyl radical which may be identical with or different from R1, x a substituent capable of metal complex formation, y the carboxylic or sulphonic acid group and wherein the nucleus A may contain further non-dissociable substituents and the complexes thereof obtained by metallization of the metal-free dyes. The dyes may be metallized in substance or on the fibre.  Metals specified include copper, nickel and chromium. The dyes are suitable for colouring wool, silk and synthetic polyamide fibres and leather.

Title: Process for the production of water-soluble acrylic polymers
Inventor: LEWIS JOHN RICHARD
IPC: C08F20/62
Filed: 1968-06-27
Abstract: 1277577 Preparing water-soluble acrylic polymers IMPERIAL CHEMICAL INDUSTRIES Ltd 18 Sept 1969 [27 June 1968] 30758/68 Heading C3P Water-soluble polymers of acryilc acid or a substituted or functional derivative thereof are prepared in substantially dry form by (a) forming an aqueous solution of the monomer and initiating polymerization, (b) adding a waterimmiscible liquid which is capable of forming an azeotrope with water and is a non-solvent for the monomer or the resultant polymer, the liquid being added whilst the aqueous solution is still fluid, (c) dispersing the aqueous solution throughout the liquid and maintaining the dispersion until polymerization is substantially complete, and (d) thereafter heating the mixture to the boil and removing water by azeotropic distillation until not more than 5% by weight of water is left in the polymer. Suitable derivatives of acrylic acid include alkali metal salts, acrylamide, methacrylic acid and methacrylamide. The monomer may be copolymerized with a monomer that, by itself, forms a water-insoluble homopolymer, e.g. acrylonitrile, methyl acrylate, vinyl acetate or vinyl chloride, in proportions that provide water-soluble copolymers. Initiators specified are potassium persulphate/ sodium bisulphite, ammonium persulphate/ copper sulphate or sodium metabisulphite, and hydrogen peroxide/ferrous salt redox systems. Liquids which may be added in step (b) include aliphatic and aromatic hydrocarbons and chlorinated derivatives thereof. A dispersing agent may be used in step (c), e.g. cellulose ethers, soya lecithin, hexadecyl sodium phthalate, sorbitan monooleate or monostearate, sodium cetyl/stearyl phthalate, ethylene oxide/ fatty acid amide condensates, Fuller's earth, talc, bentonite, calcium or magnesium carbonate, calcium phosphate or sodium sulphate; these prevent particles of the polymer coalescing during the drying step (d). In some examples polyacrylamide is produced in which some of the amide groups have been hydrolysed with caustic soda.

Title: Improvements relating to the sintering of materials such as ores
Inventor: DAVIES WILLIAM
IPC: C22B1/20
Filed: 1955-10-31
Abstract: In a process for sintering ore, metalliferous residue or concentrate the material is converted into agglomerates devoid of free moisture at the surface, a small amount of powdered hydratable lime or magnesia or both is added to the agglomerates to be taken up on their surfaces and the material charged on to a sintering grate.  The amount need not exceed 3 per cent.  The agglomerates may be formed in a rotary drum mixer fitted with lifters, and the lime added by a conveyer delivering into the drum near the discharge end thereof.  A bonding agent may be added to the material, which may be bentonite or other clay forming a jelly-like or colloidal suspension with water, e.g. an aqueous suspension of sodium bentoniet.  It is discharged on to the material before or as it enters the mixer or in the initial stages of mixing.  It may be distributed through the material by a system of ploughs on a gathering belt delivering the material to the mixer.  Clays may be added as powders.  Other suitable bonding agents are sodium silicate, starch, dextrin, or sulphate lye.  The lime may be sprinkled on to the agglomerates as finely powdered quicklime or dry partly hydrated lime.  The method is applicable to an iron-bearing material, also to lead concentrates.
