Title: Lubricant aerosol generator
IPC: F16N7/34
Filed: 1958-06-18
Abstract: 864,623. Spray-producers. STEWARTWARNER CORPORATION. June 18, 1958 [June 25, 1957], No. 19533/58. Class 69 (3). An aerosol generator includes a reservoir 3 for liquid, e.g. oil, to which a head 1 is attached having an air inlet 11 and an aerosol outlet 12. A by-pass passage 13 interconnects inlet and outlet 11 and 12 and, when the air inlet pressure is below a predetermined value, is closed by a spring-urged ball 14. A disc 7 separates an aerosol chamber 9 from the reservoir interior. A bore 18 extending laterally from the inlet 11 receives the front end of a liquid nozzle 43, and a Venturi is provided between the nozzle and bore so that the flow of air through the bore causes oil to be drawn up from the reservoir and delivered from the nozzle and formed into an aerosol. The aerosol passes into the chamber 9 before leaving the outlet 12 via an aperture 20. The oil is drawn up a tube 22 via a filter 44 and flows past a ball 28 and upwardly through a passage 37 and then down passages 39, 40 to a chamber 41 and the nozzle 43. The oil flow may be reduced by a needle valve 74 which may open a bore 72 to allow the inflow of aerosol to the chamber 41. The opening in the disc 7 through which the tube 22 passes is sealed by a spring- urged sealing ring 25. In order to fill the reservoir without interrupting the air flow a spring- urged hollow sleeve 51 is slidably arranged in the head, and is normally urged downwardly by a threaded closure plug 64 to keep open the aperture 48 and to allow the outlet pressure to be applied to the oil in the reservoir. To fill the reservoir the plug is removed whereupon the sleeve is urged upwardly and the aperture 48 closed by a sealing ring 60; liquid is then fed through the sleeve to the reservoir.

Title: Emulsified oxidised polymer oil latex
Inventor: MCKAY JOHN FRANCIS
IPC: C08C19/04
Filed: 1958-06-20
Abstract: Oily polymers of conjugated diolefins of 4-6 carbon atoms or copolymers thereof with other ethylenically unsaturated compounds which have been oxidized in the liquid phase with molecular oxygen at 20-250 DEG  C. are emulsified by forming an alkali metal salt by treatment with a water-soluble alkali metal alkali and mixing the resultant product with water.  Suitable diene monomers are butadiene, isoprene, dimethylpentadiene, piperylene and methylpentadiene, which may be copolymerized with minor amounts of styrene, paramethylstyrene, dimethylstyrene, diethylstyrene, acrylonitrile, methacrylonitrile, methyl acrylate or methacrylate, vinyl isobutyl ether and methyl-vinyl- or -isopropenyl-ketone. They may be polymerized with benzoyl peroxide or cumene hydroperoxide or metallic sodium, preferably in the presence of a solvent.  The oily polymer is oxidized by treatment with air at 20-250 DEG  C. in the presence of a solvent, which is preferably an aromatic hydrocarbon or mixtures thereof.  A catalyst such as the naphthenates or octoates of cobalt, lead, iron or manganese may be added in amounts of 0.001-1%, optionally with benzoyl peroxide. Up to 20% by weight of the polymer of oxygen may be absorbed.  The resultant oxidized oil is neutralized with sodium or potassium hydroxide, carbonate or bicarbonate, preferably in aqueous solution, to form a salt which readily emulsifies.  Where sodium is used as the polymerization catalyst this need not be removed before the oxidation and addition of water to the oxidized product forms the alkali, further addition of alkali being unnecessary.

Title: Process for the conversion of aliphatic and cycloaliphatic nitrous acid esters to the corresponding alcohols
IPC: C07C35/06
Filed: 1953-07-22
Abstract: Aliphatic and cycloaliphatic nitrous acid esters are converted to the corresponding alcohols by treating such an ester, in aqueous solution, with a reducing acid, or with a non-reducing acid in the presence of an ionisable reducing agent.  Suitable nitrous acid esters include methyl nitrite, ethyl nitrite, n-propyl nitrite, butyl nitrite, isobutyl nitrite, n-heptyl nitrite, cyclohexyl nitrite and cyclopentyl nitrite.  Suitable reducing acids include sulphurous acid, selenious acid, arsenious acid, phosphorous acid, hydrogen sulphide and formic acid.  In place of reducing acids a non-reducing acid in the presence of reducing ions introduced, e.g., by adding stannous chloride or a metal such as iron, may be used.  Elevated temperatures may be used.  The process may be applied to the mixtures of nitro-hydrocarbons and esters of nitrous acid obtained by nitration of aliphatic and cycloaliphatic hydrocarbons.  In the examples: (a) n-hexyl nitrite is treated with an aqueous solution of arsenic trioxide to give n-hexyl alcohol; (b) cyclohexyl nitrite is treated with 20 per cent sulphuric acid and powdered iron to give cyclohexanol; and (c) cyclohexyl nitrite is treated with sulphurous acid to give cyclohexanol; the starting material is formed along with nitrocyclohexane and dinitrocyclohexane by the nitration of cyclohexane.
