Altering physical structure.-A method for the treatment of journal bearings, e.g. bushes or liners of aluminium-tin alloy or of an aluminiumtin alloy facing bonded to a steel or bronze backing comprises positioning the bearing on a cylindrical die and cold working the bearing to conform closely to the die and thereafter heating the formed bearing to a temperature of from 350‹ to 500‹ C. to cause re-crystallization and dispersal of the tin-rich constituent. The cold working is effected at room temperature by a rotary tube expander of the conventional three-roll type comprising tapered rolls revolving about a central driving roller having an opposite taper, the axes of the outer tapered rolls being inclined to the axis of the central roller so that on rotation the outer rolls travel up the taper of the central roller and expand the bearing. The cold working may be carried out by applying an upsetting pressure on the ends of the bearing. After said heat treatment the bore of the bearing is machined to a predetermined size and coated with lead or tin or leadtin by electro-deposition. Specifications 680,444, 681,841 and 708,846 are referred to.

Title: Improvements in or relating to method of preparing a mixture of polymers
IPC: C08L33/20
Filed: 1951-04-27
Abstract: Dyeable fibre-forming compositions are prepared by mixing (a) an aqueous dispersion of a polymer of at least 90 per cent acrylonitrile prepared in an aqueous medium in the presence of sufficient alkali metal salt of a peroxy acid to render the dispersion acidic, and (b) a stable aqueous emulsion of a polymer of at least 15 per cent of a tertiary amine containing a polymerizable double bond, and separating the precipitated polymer blend.  Specified peroxy salts used in the preparation of the acrylonitrile polymers are sodium and potassium persulphates. Dispersing agents, e.g. sodium salts of alkylarylsulphonic acids, may also be used.  The acrylonitrile may be copolymerized with vinyl esters, e.g. vinyl acetate, styrene, alkyl acrylates or methacrylates, dialkyl fumarates and maleates, vinyl chloride and vinylidene chloride.  Specified tertiary amines are 2-vinyl-, 4-vinyl-, 5-ethyl-2-vinyl-and 5-methyl-2-vinyl pyridines, vinyl quinoline, vinyl thiazole, vinyl benzothiazole, vinyl pyrimidine, allyl pyridine, methallylpyridine, allyl quinoline, methallyl quinoline, and N-dimethylaminoethyl acrylate and methacrylate. These may be copolymerized with olefinic compounds, e.g. acrylonitrile, in an aqueous alkaline medium containing an anionic basic emulsifier such as sodium oleate and stearate. Persulphate catalysts and alkaline buffer salts may also be used. Mixing of the emulsion and dispersion results in precipitation of an intimately blended mass which can be separated by filtration and dried.  The mixture may be dissolved in a solvent such as N,N-dimethylformamide, N,N-dimethylacetamide, ethylene carbonate, butyrolactone and N,N-dimethylmethoxy acetamide, and the solutions, usually of 5-25 per cent solids, spun into fibres.
