Title: Improved fibrous article and method of manufacturing same
IPC: D01D5/42
Filed: 1963-08-10
Abstract: 1,103,141. Films and fibrillation thereof. O. B. RASMUSSEN. 11 Sept., 1964. [10 Aug., 1963; 16 April, 1964], Nos. 31676/63 and 15753/64. Heading B5B. [Also in Division D1] A fibrous product is made by forming a film of a first thermoplastic polymer in which is incorporated fibrils of a second synthetic polymer, orienting the first polymer by stretching the film and splitting the oriented film. The product comprises individual or interconnected split fibres of the first polymer and fibrils of the second polymer, the fibrils each being embedded at least partially in at least one of the fibres and transversing this or these fibres at an angle to the longitudinal axis of the fibre or fibres (Fig. 3). The mixture of first and second polymers may be extruded to form a tubular film, particles of the second polymer being drawn out longitudinally during extrusion to form fibrils, and the tubular film then cut helically to form a continuous flat film. The term " fibril " is defined as a small body of polymer having one dimension much greater than the others. In one embodiment (Fig. 7), a tubular film-forming device consists of two annular slit dies 21 and 22. The fibril-forming polymer is fed to annular orifice 33 of inner die 21 via inlets 31 and space 23, and is worked up, while still fluid, into coarse filaments by comb device 21. Shaft 26, carrying cog-wheel 27 engaging on rack 28 on top of comb 21 is rotated, thus producing a reciprocatory movement of the comb teeth 32 along the slit orifice 33. The filaments leaving the comb device, surrounded by the film-forming polymer fed to space 25, become stretched into fibrils lying close together. The film-forming (first) polymer is extruded through annular orifice 34 of outer die 22. After helically cutting the film and orientation by longitudinal stretching so that the fibrils lie at an angle to the direction of orientation (Fig. 1), the film is split into fibres by rubbing or laterally drawing it sandwiched between rubber surfaces. The orientation and splitting may also be effected in a single step. The film-forming (first) polymer may be e.g. polyethylene or polypropylene. The fibrilforming (second) polymer may be a polymer of low softening point such as polystyrene or polyvinyl chloride, or a polymer which, after splitting the film into fibres, may be cured by polymerization, cross-linking or condensation, as by a polyisocyanate process. The fibrilforming polymer may differ only in molecular weight from the first polymer. Addition of a third polymer may be made to ensure a high degree of dispersion of the second in the first polymer. The fibrous products may be formed into highly bulked yarns.

Title: Catalytic removal of organic sulphur compounds from town gas or other fuel gases
IPC: B01J27/188
Filed: 1955-11-07
Abstract: In a process for removing organic sulphur compounds from fuel gases the gases are passed at about 400 DEG  C. over a catalyst comprising a compound containing molybdenum or tungsten, phosphorus, sulphur and a metal in its molecule.  The compounds may be copper, nickel, cobalt, iron, lead, zinc or tin phosphothiomolybdate or phosphothiotungstate deposited on a carrier, e.g. activated alumina or ceramic granules.  In an example the catalyst employed contained nickel phosphothiomolybdate on a granular support.  The catalyst was prepared by dissolving 100 gms. of ammonium phosphomolybdate in aqueous ammonia, the solution being treated with H2S at room temperature, boiled to remove excess of H2S and the resulting solution containing ammonium phosphothiomolybdate was used to impregnate 300 gms. of activated alumina granules.  The granules were dried, treated with an aqueous solution of nickel sulphate and again dried and finally gradually heated to 400 DEG  C. in a non-oxidizing gas stream.  The catalyst containing the corresponding copper compound may be prepared by adding a solution of cupric sulphate in aqueous ammonia to the solution containing ammonium phosphothiomolybdate and impregnating porous ceramic granules, the granules being then dried and heated to remove ammonia and volatile ammonium salts.
