Title: Improvements in the production of carburetted water gas
IPC: C10J1/213
Filed: 1941-02-17
Abstract: 547,251. Carburetted water gas generation. ROGERS, F. H. (Fuel Research Development Corporation). Feb. 17, 1941, No. 2152. [Class 55 (ii)] Oil gas is obtained by supplying oil to refractory material moving downwards continuously through an externally heated vertical retort, and the carbon deposited on the refractory material is gasified with steam, generating water gas which passes upwards to mix with the oil gas. The retort 10 is fed with granular solid material M such as calcined clay, broken fire-brick, or coke, the charge passing slowly down the retort which is heated externally by a series of combustion chambers 20 with separate heat control in each space. Oil is admitted through a pipe 34 and preheater 36, and vaporizing and cracking of oil takes place, resulting in the deposit of carbon on the material. Steam from a pipe 40 cools the residue in chamber 30, and the heated steam passes upwards into the retort, and generates water gas by action on the deposited carbon, additional steam being supplied if required through pipe 44. The water gas travels upwards through the retort and mixes with the oil gas, the carburetted water gas being withdrawn through pipe 37 leading to a fractionating column 38 for separating the liquid and gaseous products, and condensing the various liquid products.

IPC: D05B3/02
Filed: 1918-02-07
Abstract: 123,794. Fairweather, W., (Singer Manufacturing Co.). Feb. 7, 1918. Multiple-needle sewing-machines; extra threads, attaching; chain-stitching, seams. - Relates to sewing-machines, such as described in Specifica.- tion 122,905, and consists in the mechanism for uniting the meeting edge-portions of material to form a fiat seam. The stitching mechanism comprises two pairs of needles 20, 21, Fig. 7, arranged at right-angles to the line of the seam, each pair co-operating with a threaded looper. The forward pair of needles 20 are. spaced more widely than the rear pair 21, and co-operate with devices for laying a surface thread. The needlebar 23, Fig. 2, is reciprocated by a lever 28 pivoted at 31 to a pitman-lever 30 driven by a crank 32 on the main-shaft 6. The looper-shaft 37 carries a crank 38 which is connected by a link 39 to the upper end of the lever 30. The link 39 is anchored by a link 44 extending in the general direction of the needle-actuating lever and loopershaft, and the arrangement is designed to produce a dwell in the sideways movement of the loopers during their loop-seizing strokes. The surface-thread laying devices comprise a threadcarrying finger 102 adapted to reciprocate in the line of the seam and a spreader 115 reciprocating across the seam. The finger 102 is adjustably secured to a bell-crank lever 104 pivoted on a horizontal stud 108 and actuated by the link 109, bell-crank 110, and link connexion 112 with the needle-actuating lever, the connexions providing for a dwell in the motion of the thread-laying devices during the first part of the down-stroke of the needles. The spreader 115 oscillates about a vertical axis and is driven by a link connexion 121 from the lever 104. The seam produced by these devices is shown in Figs. 10 and 11, in which c, d indicate the loops of thread formed by the forward needles 20, and e the co-operating looper thread, h, i the loops of thread formed by the rear needles 21, and j the co-operating looper thread, and f the surface thread. The arrangement of threads shown in Fig. 10 is that obtained when the spacing of the pairs of needles is a multiple of the stitch-length; the staggered relation of the loops shown in Fig. 11 is obtained when this relation between the spacing of the pairs of needles and the stitch-length is altered.

Title: Improvements in or relating to cellulosic textile materials
IPC: D06M14/22
Filed: 1962-01-23
Abstract: The crease resistance of cellulosic textile materials, e.g yarns threads and woven, knitted or unwoven fabrics composed wholly or partially of natural cellulose such as cotton, regenerated cellulose or cellulose derivatives such as cellulose acetate is improved by treating the materials with a sensitiser which is an ethylenically-unsaturated organic compound, an aromatic compound or a primary, secondary or tertiary amine in a proportion sufficient to sensitise the cellulose to irradiation without causing any changes in its appearance or finish, subjecting it to ionising radiation able to penetrate the material without inducing substantial radioactivity therein, e.g. gamma radiation, X-rays and accelerated electron radiation, at a dosage less than 107 rad and then contacting it, preferably at a temperature above 40 DEG C., with a substance able to undergo graft reaction with substances having free radicals, with the exception of aldehydes or condensable substances as defined in Specification 930, 427, to effect grafting between the graftable substance and the cellulosic textile material.  In a modification of the process the irradiation and grafting are carried out simultaneously by treating the material first with the sensitiser and then with the graftable substance and then irradiating.  The sensitiser may be an aromatic hydrocarbon having 1-4 rings either condensed or uncondensed, an aliphatic compound having 4-20 carbon atoms in a chain and 1-3 isolated or conjugated double bonds or an aromatic saturated or unsaturated ketone, preferred sensitisers being 1,4-diphenyl benzene, pyrene and 1,4-diketo 2,3-dihydronaphthalene. Suitable sources of gamma radiation are Co60 and Cs137 and the accelerated electrons which preferably have an energy of 0.50-0.6 Mev may be generated by cascade, Vander Graaf or linear accelerators or radioactive sources such as Sr90 may be used.  The graftable substances may be polymerizable monomeric compounds, e.g. acrylamide, acrylates, methacrylates, styrene, vinylacetate, vinyl chloride, vinylidene chloride, ethylene, tetrafluorethylene, butadiene, isoprene and divinyl sulphone, substances incapable of polymerization, e.g. alcohols, ketones, acetals, halogenated hydrocarbons, amines, esters, ethers and phenols, or fully polymerized compounds, e.g. polyethylene, polymethacrylates and polyvinyl chloride.  The sensitisers and the graftable substances may be applied to the cellulosic materials in the form of a solution or dispersion in water or an organic solvent. Transparentised fine fabrics obtained by the treatment of cellulosic fabrics with sulphuric acid, cuprammonium solution or sodium zincate cellulose solution and fine cellulose fabrics composed or relatively high twist yarns, e.g. voiles and marquisettes, may be treated. Specification 895, 478 also is referred to.
