Title: Fabric
IPC: B29D30/38
Filed: 1964-08-28
Abstract: A continuous chafer fabric is prepared by weaving a tubular fabric, wick-proofing the fabric, tackifying the wick-proofed fabric and bias cutting the tubular fabric at any stage subsequent to the weaving thereof.  After wick-proofing and for tackifying, the fabric is dried in a tenter frame.  Wick-proofing involves treating the fabric so that air cannot leak out of the interior of the tyre by 'wicking' along the yarns and polymeric material of the carcass.  Specified wick-proofing baths contain a vinyl-pyridine/butadiene/styrene terpolymer, dispersions of latex and resorcinol formaldehyde solutions, dispersions or solutions of acid catalyzed regorcinal formaldehyde and butadiene vinyl-pyridene copolymer, solutions or dispersions of resorcinal formaldehyde with neoprene or with bromine containing iso-olefine-polyolefine interpolymer, or combinations of the above.  Tackifying includes both calendering green rubber on to the fabric and dipping or padding with tackifying coating compositions.  Specified tackifying baths are solutions or emulsions of pressure sensitive adhesives.  Solutions of raw rubber, e.g. smoked sheet rubber dissolved in organic solvents such as benzol or naphtha, are specified.  The bias cutting may be a single operation or a number of cutting operations taking place either simultaneously or at various stages of the process. The bias cutting angle is preferably between 40 degrees and 50 degrees, e.g. 45 degrees.  The fabric which has been wick-proofed alone or both wick-proofed and dip coat tackified may be coated with rubber or other elastomers by passage of the treated fabric together with green rubber into a friction calender.  The fabric may be made of rayon, nylon, polyester or cotton yarns. Continuous filament rayon or nylon yarns are specified.

Title: Improvements in or relating to the preparation of sulphur for transport
Inventor: ELLIOTT HERBERT JAMES
IPC: B65G53/30
Filed: 1966-08-11
Abstract: 1,203,031. Sulphur. ELLIOTT ASSOCIATED DEVELOPMENTS Ltd. 9 Aug., 1967 [11 Aug., 1966], No. 36083/66. Heading CIA. A method of preparing sulphur for transport by pipe-line in a carrier liquid comprises introducing molten sulphur into a liquid medium different from the carrier liquid to create a dispersion of solid sulphur particles in said different liquid medium, separating the sulphur particles from at least the bulk of the different liquid medium and blending them into the carrier liquid for transport. Molten sulphur is introduced, preferably at 128‹ C. into a light oil fraction in vessels 11 equipped with stirrers 26. The dispersion of sulphur produced is withdrawn by means 12 and passed through two stages of a three-stage heat exchanger, preferably a plate heat exchanger, 14 in stage 21 being in counter current with stripped oil and stage 20 cooled by water. From the heat exchanger the sulphur dispersion passes to a precipitation tank 23 having a stirrer 25 and from there to a hydrocyclone or centrifuge 15 where the sulphur is stripped from the oil. The sulphur passes into a blending tank 24 stirred by stirrer 31 where it is blended with carrier liquid and, if desired, sulphur in granulated form produced by known methods. The stripped oil passes to a tank 16 from where it passes to two stages 21, 22 of the heat exchanger 14, in stage 22 being heated by steam prior to passing to the vessels 11. The sulphur blended with the sulphur produced according to the invention may be made by passing molten sulphur through fine nozzles into a granulator which has an impeller operating counter to a swirl produced in a cooling liquid by tangentially disposed nozzles, Fig. 2 (not shown).

Title: Process for the preparation of gases and/or liquids entirely or substantially free from carbon oxysulphide
IPC: C10G25/00
Filed: 1966-08-15
Abstract: Gases and/or liquids which are at least partly immiscible with water and which contain COS as impurity, e.g. low boiling liquid hydrocarbon oil fractions, refinery and other industrial gases, and liquefied natural gas (including ethane, propane and butane), are purified by contacting them with a concentrated aqueous salt solution containing at least one alkali metal phosphate and having a pH of at least 9, and separating the gases &c. from the solution.  The COS is hydrolysed to H2S and CO2. Potassium phosphates are preferred and may be in part replaced by other alkali metal salts, e.g. sodium and potassium carbonate and chloride, and lithium acetate.  The process may be carried out at temperatures up to 200 DEG  C. and at pressures up to 100 atmospheres, and may be followed by conventional H2S and/or CO2 removal with aqueous caustic alkali or an alkanolamine. Contacting of the fluids with the solution in the first step may be by propeller or centrifuge mixing apparatus, or, in the case of gases, in columns provided with atomizers, bubble trays or packing material.  The water content of the fluid may be adjusted before the contacting, e.g. by drying over alumina or by adding water. The contacting is preferably performed in two stages in series, with an intermediate separating stage where the fluid being purified is a liquid. Contacting times are at least 10 seconds for gases and 5 minutes for liquids.  In a modification, the phosphate solution is impregnated on to a carrier, e.g. silica and/or alumina, activated carbon, and natural materials, e.g. fuller's earth, bauxite, clays &c., and the carrier dried. In one example, a fixed bed of activated carbon contained, after drying, 6% b.w. tripotassium phosphate in a 45% solution.  The carrier bed may be in dispersed or fluidized form.
