Patent GB-872310-A (GB)
Title: Liquid fuel compositions
IPC: C10L1/188
Filed: 1958-06-27
Abstract: Anti-knock performances of leaded or unleaded gasolines having an original performance number of at least 90 (97 octane number) are improved by the addition of one or a mixture of compounds selected from sodium and potassium salts of organic carboxylic acids containing from 4 to 18 carbon atoms.  Aliphatic and cycloaliphatic acids with or without aromatic substitution are exemplified by 2-methyl- and 2,2-dimethyl-propionic acids; 3-methyl-3-phenyl-, 2-methyl-, 2,2-dimethyl-, and 3 - methyl - 3 - cyclohexyl - butanoic acids; 2,2,4,4-tetramethyl-, 2,3-dimethyl-, 2-ethyl-4-methyl-, and 2-propyl-4-methyl-pentanoic acids; 1,2,2,3-tetramethyl-cyclopentane carboxylic acid; 3,5,5-trimethyl-, 2-ethyl-, 2,2-diethyl-, 2-methyl-, and 4,5-dimethyl-hexanoic acids; 1-methylcyclohexane-1-carboxylic acid; naphthenic acids derived from petroleum; oleic acid; and undec-10-en-1-oic acid.  The compounds are normally introduced with the fuel into the engine cylinder but may be introduced therein separately as a powder or with solvents, e.g. in water/alcohol mixtures for aircraft engines or tetraethyl lead/alcohol mixtures for automotive engines.  A fuel of performance number 90 is one whose knock resistance by the F-1 Research Method (ASTM D-908-51) is equal to or greater than the knock resistance of a blend consisting of 97% isooctane and 3% n-heptane.  The compounds of the invention, which are used in amounts equivalent to 0.05 gram to 5.0 grams of sodium or potassium metal per U.S. gallon of fuel, are effective in unleaded fuel and in fuels containing up to 6.0 ml. of tetraethyl lead per U.S. gallon.  Conventional fuel additives such as dyes, antioxidants, &c., may be incorporated into the fuel.  The solubility of the sodium and potassium salts in the fuel is enhanced by the use of blending agents such as alcohols, glycols, esters, ketones, and amides.  In examples isopropanol is used as blending agent.

Title: Improved process for the coloration of polymers and copolymers of vinyl chloride
IPC: C08J3/22
Filed: 1952-08-18
Abstract: Plasticised polymers or copolymers of vinyl chloride are coloured by incorporation of a dye or pigment concentrate which is a mixture of dye or pigment with a plasticised polymer or copolymer of vinyl chloride having a lower working temperature, i.e. the plasticised mass may be rolled or extruded at a lower temperature.  The concentrate is preferably in the form of a powder of particle size less than 1/10 mm., obtained, for instance, by the use of a high concentration of dye or pigment or by the addition of an inert additive such as talc.  For the colouration of polyvinyl chloride the concentrate may be derived from polyvinyl chloride of a lower degree of polymerization, chlorinated polyvinyl chloride, or copolymers of vinyl chloride with vinyl acetate, vinylidine chloride, or methyl or ethyl maleate or fumarate.  In examples, the plasticisers used are dibutyl and dioctyl phthalates, the colouring materials used are diazotized Tobias acid (Vulofix Red), ultramarine blue and chrome yellow, and various working temperatures are specified.  Tubes and profiled elements may be obtained.

Title: Improvements in processes and apparatus for making sulphur dioxide and sulphuric acid
IPC: C01B17/54
Filed: 1925-08-19
Abstract: Sulphur dioxide is produced by using sulphur as fuel in an internal-combustion engine working on the Diesel or like constant pressure principle.  The exhaust gases may be passed into a chamber or burner in which any residual sulphur is oxidized, and the sulphur dioxide, after purification, if this be necessary, and possibly after adjustment of its temperature, may be converted to sulphuric acid by the contact process.  To avoid corrosion the air supplied to the engine is dried, and the sulphur may be introduced into the cylinder after being melted by means of super-heated steam or by the heat of the combustion gases.  The melting pot may be let into a wall of the combustion chamber in which the residual sulphur is burned. Specification 238,621 is referred to.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the production of the sulphur dioxide in an internal-combustion engine of any type. This subject-matter does not appear in the Specification as accepted.ALSO:Sulphur dioxide is produced by using sulphur as fuel in an internal-combustion engine working on the Diesel or like constant pressure principle.
