Title: Filter for tobacco smoke
IPC: A24D3/08
Filed: 1967-02-24
Abstract: 1,149,115. Tobacco smoke filters. CHISSO CORP. 24 Feb., 1967 [24 Feb., 1966], No. 8958/67. Heading A2C. [Also in Division D1] A tobacco smoke filter comprises a core formed of split fibres of an oriented linear high molecular weight material, the split fibres having a network structure, more than 50% of the split fibres having a denier of 2 to 20, the split fibres being bundled into cyindrical rod like form and the core being enclosed in an outer wrapper. Orientation of the high molecular weight material is effected by stretching a film of the material, with the aid of heat if necessary, prior to splitting. The splitting is effected by means of a coarsely abrasive cutting surface such as a rotating file or tap-like cutter, or less preferably a rotating wire brush or wire cloth cutter. The preferred film materials are polypropylene and cellulose acetate; also specified are polyethylene, polyesters, polyamides, polyvinylacetate, polyacrylonitrile, and regenerated cellulose. Crimped fibres may be produced either from the fibres by conventional crimping apparatus or by forming a film having different coagulation velocities at its two surfaces and treating the surface with the faster coagulation velocity with the coarsely abrasive surface. Optionally the fibres may be sprayed with a binding agent prior to forming into a rod.

Title: Anthraquinone dyestuff compositions
Inventor: HESLOP ROBERT NORMAN
IPC: C09B62/06
Filed: 1956-03-23
Abstract: The invention comprises anthraquinone dyestuff compositions consisting of, in the free acid or salt form, a dyestuff of the formula <FORM:0838335/IV(c)/1> where X is an aromatic bridging group containing at least one anionic solubilizing group and Y is chlorine or bromine, and a solid buffer whose aqueous solution has a pH of from 6 to 8.  The bridging group X may be a phenylene group, a group -C6H4C6H4- or a group -C6H4-N=N-C6H4-, each of which is substituted by an anionic solubilizing group such as a sulphonic acid or carboxylic acid group, and may be further substituted by alkyl, alkoxy or halogen.  The buffer may be a mixture of sodium dihydrogen phosphate and disodium hydrogen phosphate or of disodium hydrogen phosphate and potassium dihydrogen phosphate. The composition may be made by mixing or milling the dye with the buffer, by addition of the buffer to a moist dyestuff paste before drying, by washing the dyestuff with an aqueous solution of the buffer, or by addition of the buffer to the reaction mixture in which the dyestuff is made, before, during or after the preparation.  The composition may also contain diluents such as urea, Glaubers salt or sodium chloride.  The dyestuff is made by reacting, in free acid or salt form, a compound of the formula <FORM:0838335/IV(c)/2> with one molecular proportion of cyanuric chloride or cyanuric bromide.  The amines of the above formula are made by reacting 4-bromo - 1 - aminoanthraquinone - 2 - sulphonic acid in aqueous alkaline medium with an aromatic diamine containing at least one anionic solubilizing group.  Aromatic diamines specified are m-phenylenediamine-4-sulphonic acid, p-phenylenediamine-2-sulphonic acid, 4 : 41-diamino - azobenzene - 2 - sulphonic acid, p-phenylenediamine -2-carboxylic acid and benzidine -3-sulphonic acid.  In examples, dyestuff compositions are made from dyes prepared by reacting cyanuric chloride with (1) 1-amino-4-(41 - aminoanilino) - anthraquinone - 2 : 31 - disulphonic acid; (2) 1 - amino - 4 - (31 - aminoanilino) - anthraquinone - 2 : 41 - disulphonic acid; (3) 1 - amino - 4 - (31 - amino - 61 - methyl) -anilinoanthraquinone - 2 : 41 - disulphonic acid; (4) 1 - amino - 4 - (31 - amino - 21 - methyl) - anilinoanthraquinone - 2 : 51 - disulphonic acid; and by reacting cyanuric bromide with (5) 1-amino - 4 - (31 - aminoanilino) - anthraquinone - 2 : 41-disulphonic acid.

Abstract: 952,489. Endless belt conveyers. JUENGEL V-MATIC SYSTEMS Inc. March 14, 1961 [March 25, 1960], No. 9280/61. Heading B8A. The upper run 16 of an endless conveyer belt 2 driven by a motor 24 is supported in a shallow channel 14 formed on the top surface of a tubular carrier member 1, and the lower run 17 of the belt is supported on the lower inner surface of the carrier. The top surface of the belt run 16 lies above shoulders 13 forming the channel 14 and hooks 7 of garment hangers 6 thus contact only the top surface of the run 16. A roller device 34 holds down the run 16 in the region 33 but the belt is of sufficient elasticity to permit the hooks 7 to pass beneath the roller which may be free or positively rotated. To permit the belt to change direction in the plane of travel of the goods, the run 16 passes around a pulley 35 having radial recesses 38 which provide clearance for the hooks 7. A guide member 39 slidably supports the hooks as they move from the carrier member 1 to a further carrier member 36. The lower run 17 of the belt passes around a pulley 44. The hangers 6 slide on to the conveyer down an inclined supply member 31 and are discharged on to an inclined bar 28. Support members 3 are secured, e.g. soldered or brazed, to the carrier members. The belt may be of rectangular, oval or circular crosssection and may be ridged or serrated to increase the grip in moving the goods. One or more conveyers may support directly articles on the top surfaces of the upper belt run.

Title: Gaseous fuel burners
IPC: F23D14/06
Filed: 1972-04-19
Abstract: 1370326 Gaseous fuel burners RADIATION Ltd 19 April 1972 [19 April 1971] 9792/71 Heading F4T A gaseous fuel burner head comprises at least one body member and a cap defining a gaseous fuel supply chamber, the burner head having a first flame port (49) and the body and cap defining a first gaseous fuel passageway between the chamber and one part of the first flame port and also a second gaseous fuel passageway between the chamber and another part of the first flame port. The head also incorporates at least one second flame port (28) supplied by a further gaseous fuel passageway in non-communicating relationship with the first port and its fuel supply. As shown, the head comprises three body members 1, 2, 3 and a cap 4. The three body members are mounted one on top of the other and are shaped so that they rest together in the correct orientation. The locating means between the first two members 1 and 2 is provided by an annular ridge 7 on the upper surface of member 1 and an annular recess 9 in the lower surface of member 2, there being a pin (8a) which locates in recess 8 to ensure correct orientation of the two members relative to each other. The locating means between the members 2 and 3 is an annular ridge 21 on the lower surface of member 3 and an annular trough 12 in the upper surface of member 2. The cap 4 is provided with downward extensions 35 which nest in slots 32 to locate the cap with respect to the other members. The body members together define a first gaseous fuel duct 5, 10, 30 which widens out under the cap to form a first fuel supply chamber. The fuel flows from this chamber to a first set of flame ports (49) via the passageways 43 (between castellations (37) and via the passageway 39 (more clearly illustrated in Figs. 8 and 9, not shown) and the second chamber 40. This second route has greater resistance against fuel flow and thus the fuel emerges at the lower parts of ports (49) at a lower velocity than the fuel emerging from the upper parts. The lower flame from the gas at low velocity thus acts to stabilize the flame from the gas at higher velocity. A second duct 6 is defined by members 1 and 2 and leads to a third chamber 12 from where the fuel passes to a fourth chamber 24. The fuel then passes through either a third passageway to a set of second ports 28 or a fourth passageway to a set of third ports 48, this fourth passageway having greater resistance to flow than the third passageway arid the flame from the ports 48 stabilizing the flame of the ports 28. The ports 28 and 48 form "simmer" ports and have a lower thermal capacity than the first flame ports 49 and the fuel supplies to the main and "simmer" ports may be regulated by a multi-position tap.
