Title: Improved resinous lacquers or enamels and products therefrom
IPC: C09D161/28
Filed: 1942-01-08
Abstract: A wire baking lacquer or enamel comprises a solution, in a suitable solvent, of a heat-hardenable cresol-modified melamine-aldehyde condensation product together with a polyvinyl acetal resin.  The cresol-modified resin is prepared by reacting a melamine-aldehyde resin with cresol, either at room, or preferably, at elevated temperature with the aid of a catalyst; thus, a melamine-aldehyde resin, in solution in butanol or a mixture of xylol and butanol, is heated with cresol containing 50 per cent of metacresol, under reflux at 110 DEG  C. using triethanolamine or other alkaline catalyst, until no free cresol is left, the solvent being then removed by distillation.  The prepared resin is dissolved with twice its weight of a polyvinyl acetal resin in a mixture of heavy coal tar naphtha and ethyl lactate.  In a modification, the melamine-aldehyde resin and the polyvinyl acetal resin are dissolved in cresol and reaction allowed or caused to take place to convert the melamine-aldehyde resin to the cresol-modified resin.

Title: Fabric
IPC: B29C41/28
Filed: 1965-04-02
Abstract: A moisture-pervious non-woven polyamide fabric is made by dissolving a polyamide at elevated temperature in a liquid that is a non-solvent at room temperature but a solvent at elevated temperature, forming a layer of such solution by distributing it over a surface, cooling the layer of solution to achieve formstability and removing the solvent from the form-stable layer.  The solution may be cooled to a temperature at which said liquid is a non-solvent thereby forming a solid solution and removing the solvent from the solid solution.  The solvent may be removed by vapourization, e.g. under vacuum, or by leaching, preferably by means of a hot water bath, or by vacuum distillation.  The form stable layer may be calendared and embossed. The surface may be of a fibrous material preferably woven, knitted or felted cloth.  The fibrous material may be coated with the solution and the coating may be aided by subjecting the distributed layer to pressure.  The solvent may be certain monohydric alcohols or a polyhydric alcohol, e.g. a glycol such as ethylene glycol, preferably triethylene glycol, propylene glycol and glycerine.  The solution may be sprayed on to and distributed over the fibrous surface by doctor blades and smooth calender rolls.  Examples of polyamides are given.

Title: Improvements in or relating to the operation of machinery exposed to atomic radiation
IPC: G21F7/06
Filed: 1958-05-02
Abstract: A radiation-resistant lubricant comprises a mineral lubricating oil and a minor proportion of an oil-soluble polymer which contains benzene rings in its molecule.  The proportion of polymer employed is sufficient substantially to prevent increase in the viscosity of the lubricating under the influence of atomic radiation.  The lubricant may be employed for lubricating the relative movable parts of machinery contained in any atomic plant, including atomic power plant, vehicles and machinery used in atomic warfare and machinery-containing plant used in nuclear research and development projects.  The polymer may be hydrocarbon or it may contain atoms other than carbon and hydrogen, such as oxygen and nitrogen.  Thus it may be a polyester (such as a condensation product of phthalic anhydride with glycerol), a polyamide (such as a condensation product of phthalic anhydride with 1,6-diaminohexane) or a low molecular weight phenol-aldehyde condensation product (such as a phenol-formaldehyde condensation product).  Hydrocarbon polymers mentioned are alkylated styrene polymers, and copolymers of styrene or alkyl-substituted styrene with one or more olefinic hydrocarbons, such as butadiene, propylene, ethylene or butylene.  In an example, 0,9% by weight of a polystyrene alkylated with nonylene (triisopropylene) is added to mineral lubricating oil.

Title: Production of shaped toughened polystyrene articles of low density
Inventor: COOK JOHN MAITLAND
IPC: C08J9/04
Filed: 1962-04-13
Abstract: Toughened polystyrene particles comprising a blowing agent are injection-moulded to give a shaped article having a density between 15 and 55 pounds per cubic foot, the quantity of blowing agent originally present being such as to give the required density. The toughened polystyrene may be a mixture of a styrene polymer and a rubber, or a graft polymer of a rubber and styrene with or without another monomer such as acrylonitrile, vinyltoluene and a -methylstyrene.  A natural or synthetic rubber may be used, e.g. a diene polymer or copolymer which may be derived from butadiene or isoprene.  The rubber may be present to the extent of 3-12% by weight of the toughened polystyrene. The blowing agent may be chemical, e.g. ammonium or an alkali metal bicarbonate, or an organic N-nitroso, azo, diazo or hydrazo compound, or physical, e.g. a volatile solid or liquid such as pentane or other hydrocarbon, or an adsorbed vapour. Blowing agents may be incorporated during polymerization or by tumbling optionally in the presence of an adhesive such as a mineral oil or in the case of a volatile liquid by steeping or by exposing the polystyrene particles to the vapour.  Generally 0.05-3% by weight of blowing agent is used but 4-10% or even 15% may be used in moulding thin sections. A nucleating agent is preferably included, e.g. a metal stearate or a hydrated inorganic solid such as hydrated silica or salts containing water of crystallisation. Alkali metal bicarbonates may be used as blowing and nucleating agents, preferably in conjunction with an acid salt such as an alkali metal citrate. 0.05-5% of nucleating agent may be used. It may be introduced by a tumbling or extrusion technique. The process may be used to mould shoe heels or cotton reels.
