Title: Improvements in or relating to gas turbine plant
IPC: F02C3/26
Filed: 1946-09-16
Abstract: 616,864. Gas turbine plant. BABCOCK & WILCOX, Ltd., DAVY, C. H., and WEBB, T. B. Sept. 16, 1946, No. 27719. [Class 110 (iii)] [Also in Group XII] Granular fuel is burnt in a chamber 4 to provide working fluid for a gas turbine plant. The fuel, entrained by compressed air, enters the chamber by a tangential nozzle 7 and secondary compressed air enters by a nozzle 8. The fuel is thrown, by the whirling motion, on to the chamber wall which, during operation, is sticky with molten ash. The molten ash runs down the chamber wall and is evacuated under pressure at 22. The whirling combustion products descend through an opening 20 formed by a conical partition 18 and, in the lower chamber 5, are cooled by admixture with compressed air admitted through tangential openings 42. The chamber 5 operates as a cyclone separator, the cooled ash being collected in the hopper-like .part 50 and the separated hot gases passing upwards into a pipe 55 by which the gases are conveyed to the turbine. The chambers 4, 5 are enclosed in a pressure casing 6 and cooling air from the line 43 passes between the walls of the casing and chambers. The additional air admitted to the chamber 5 is pre-heated in passing through the casing 6 from the lines 43 by finned pipes 27 forming part of a closed system for cooling the walls of the chambers 4 and 5. This system includes a circulating pump 41 delivering to a header 52 from which pipes imbedded in the chamber walls lead to a header 26. Thence, the heated fluid passes through the pipes 27 to a header 29 and back to the pump. The conical partition 18 is cooled by means of an imbedded pipe coil. The fuel is in granular form; the particles being not greater in size than half an inch, all or the great majority being less in size than one-fifth of an inch and considerably less than 20 per cent being fines. Air from the compressor 57 is heated in an exchanger 60 by the turbine exhaust and passes to the fuel pipe 9, the secondary air pipe 15 and the cooling air line 43. The exchanger may be byepassed by pipe 62. Fuel from a hopper 14 is fed into the air stream in the pipe 9 by a screw feed 12. In a modified plant, the finned pipes and header 29 are omitted. The cooling fluid goes from the header 26 to a heating coil submerged in a vapour generator and is returned to the header 25. The vapour is superheated by being used as the cooling fluid in the pipe coil in partition 18 and is admitted to the turbine with the combustion products.

Title: A new or improved apparatus for "marbling" paper
Filed: 1919-11-12
Abstract: 160,872. Jackson, W. J. Mellersh-, (Orcutt, C. C.). Nov. 12, 1919. Coating materials in long lenaths.-A machine for producing in a continuous manner on a web of paper a marbled or mottled finish on a coloured or white ground comprises means for coating the paper with ground colour or water, means for spattering drops of colour on to the wet surface, compressed air jets directed on to the paper to spread and blend the colour drops, and heating means for quickly drying the web and setting the colours. In the arrangement shown, the paper web is drawn from a supply roll 1 and receives an application of ground colour or water from feltcovered rolls 5, 6, which rest upon and are driven frictionally by the colour-rollers 7, 8, rotating in the colour-trough 9. The web then passes round a drum 10, where surplus liquid is removed by an adjustably-mounted squeegee 11, and the remaining liquid is spread evenly over the paper by a felt-covered longitudinally reciprocated pad 17. Flecks of marbling colours are then spattered on the web by brushes 33 rotating in contact with rollers 29, 31, rotating in colour troughs 28, 30, and are spread and blended by jets of compressed air from nozzles 38 on pipes 35, which are flexibly connected to the air supply and are reciprocated over the web so as to form waves or sinuous lines of colour. The web thence passes over an arched support 44 heated by gas-burners 47 and preferably faced on the top with a layer of woven wire 45 to distribute the heat evenly, so that the paper may be dried quickly, thereby preventing excessive spreading of the colours, without danger of injury to the paper or to the colouring- material. From the arched support, the web passes round a heated drum 46 and is led over a series of cooling-fans 63, being supported at this stage between lower tapes 67 and endless upper tapes 66. The finished product is wound up on the winding-drum 75. Means are provided for lifting the web from the arched support to prevent it from overheating if for any reason the machine is stopped, comprising transverse ends 48 underlying the paper and supported at the ends of vertical hinged arms 49, which are connected by rods 50 to a manipulating arrangement at the centre of the arch consisting of links 52 and vertical push-rod 54. Means are provided for lifting the paper off the coating-rolls when the machine is stopped, said means preferably being operated automatically by the device for lifting the paper off the heated arch, and comprising a transverse rod 56 underlying the paper between the coating-rolls 5, 6, and supported by links 57 from levers 58. One of the latter is adapted to be engaged by a pin 59 carried on the end of one of the vertical arms 49 of the device for raising the paper off the arch. Specification 12645/07, [Class 31, Cutting &c.], is referred to.
