Abstract: 962,057. Gas turbine plant; gas turbine blades. B M W TRIEBWERKBAU G.m.b.H. April 24, 1962 [April 25, 1961], No. 15571/62. Headings F1G and FIT. A gas turbine engine comprising a radial or diagonal outward flow combustion chamber located between a radial or diagonal flow turbine and a radial flow compressor has supporting plates, between the chamber and the turbine and between the chamber and the compressor, locating seals and the chamber walls, such that the supporting plate between the chamber and the turbine is rigidly fixed to a cold part of the turbine casing by elements extending through the hollow nozzle vanes of the turbine, whereas the turbine nozzle ring is fixed to this assembly or to other structural parts of the gas turbine in a manner permitting relative movement by thermal expansion. A supporting plate 4, Fig. 1, carrying a labyrinth seal is located between the turbine 1 and the wall 3 of a combustion chamber 2. A similar supporting plate (not shown) is located on the compressor side of the combustion chamber 2. The plate 4 is rigidly secured to the turbine casing 10 by a screw 9 in a bush 6 passing through the hollow turbine nozzle vane 5 and flanges 7 and 8. Screw 9 also secures the combustion chamber wall 3. The nozzle vane ring 11 is connected, for example welded, to the flanges 7 and 8 with the interposition of expansion joints 12 and 13 such that cold compressor air 15 passes through the vanes 5. In a modification, Fig. 2, the supporting plate 4<SP>1</SP> is fixed to the turbine casing 10<SP>1</SP> by bolts 16 passing through bushes 6<SP>1</SP> and nuts 17, 18.

Abstract: 357,577. Crape yarns and fabrics. BRITISH CELANESE, Ltd., 22, Hanover Square, London, DICKIE, W. A., and MONCRIEFF, R. W., of British Celanese, Spondon, near Derby. May 24, 1930, No. 16017. [Classes 120 (iii) and 142 (iv).] In the production of crape yarns, artificial filaments of fine denier such as 2, 1¢, 1 or even less are used and a high twist is imparted thereto preferably in two or more stages. A relatively large proportion of the twist is imparted in the first or an early stage of the twisting and a higher degree of twist, up to 80-85 or more turns per inch; may be used. By using yarns of 150 denier composed of this finer filament a more pronounced craping effect is obtained. The sizing is effected as in Specification 357,576. The process is applicable to any kind of artificial filament such as viscose, nitrocellulose, and cuprammonium, but yarns of cellulose acetate or other organic derivatives of cellulose such as cellulose formate, propionate and butyrate, and of methyl and benzyl cellulose, used either alone or mixed together, or mixed or doubled with natural filaments or fibres are particularly suitable. Specifications 348,589, 351,999, 352,000, 352,451, 356,233, 357,084, and 357,169 are also referred to.

Abstract: 586,555. Gas turbines. BAUMANN, K., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Dec. 15,' 1941, No. 16190. [Class 110 (iii)] A gas turbine plant which may be used for jet propulsion of aircraft or supercharging an I.C. engine, or, in air-conditioning or refrigerating plant, comprises a contra-rotational air-compressor driven by contra-rotational turbine discs 36, 37 which are axially beyond the compressor.

The combustion chamber is of annular swan-neck form and delivers products of combustion to fixed bladings I which precede the turbine bladings II, III. The exhaust is received by fixed bladings IV. The air-compressor rotors are driven through tubular shafts or sleeves 15, 39 and there is a bearing 43 between the sleeves. In one modification the fixed blading ring IV is omitted and the outer compressor rotor is directly connected to the foundation ring of the blading III. Modifications of the driving sleeve and bearing arrangements are described.

IPC: B65B7/28
Filed: 1961-05-04
Abstract: 938,438. Packaging. VACUUMATIC Ltd., and JOHN GOSHERON & CO. Ltd. March 21, 1962 [May 4, 1961], No. 16231/61. Class 94(1). Tacky closures for a container 18 such as a tin of biscuits are stripped from a continuous supporting band 6 and pressed on to the containers. The closures may be cut from a continuous strip carried by the band 6 but, in the form illustrated, separate closures, each comprising a synthetic resin sheet, a sheet of prepared paper, or a piece of aluminium foil laminated to paper, and each coated with a tacky latex, are spaced on the upper face of the band 6 which is fed from a roll 5. The band is bent sharply about the edge 9 of a supporting plate 8 so that the closures project at 15 from the end of the plate. In this position the machine is stopped, under the control of a photo-cell device 16, 17, until an operator has inserted a container 18 in the correct position and closed an access flap. A bar 22 then presses the closure on to one edge 23 of the container and is immediately retracted. The container 18 is then pushed to the left in Fig. 1 by a plunger 26, and simultaneously the web 6 is fed so that the closure is pressed on to the container by a spring-biased roller 33 as the container passes to a position above a platform 27. As the platform 27 subsequently raises the container, rollers 36, 37, 38 fold the margins of the closure down on to the sides of the container. Finally a foot 39 on the platform 27 engages the roller 37 so that the platform 27 is tipped about a central pivot to discharge the container 18 on to a shoot 40. All the movements of the machine are effected pneumatically under the control of solenoids controlled by limit switches which ensure that the container 18 is correctly inserted, that the access flap is closed, and that the container 18 has completed its movement into position above the platform 27, before operation of the machine can continue. The machine may close several containers simultaneously. The container openings need not be rectangular, and may be non-planar. The machine is capable of adjustment to suit containers of different sizes. To prevent the adhesive contacting the contents of the box, the box may have an inner liner, or each closure may be masked by a piece of paper cut so that only its peripheral portions are left on the web 6. A neon may indicate when the machine is in operation.

Abstract: 111,479. Axien, J. H., and Jurgens, J. Nov. 11, 1916, [Convention date]. Void [Published under Sect. 91 of the Act]. Movable-abutment type.-Two or more vanes, carried by separate shafts concentric with the casing, are operated by rods which rock and rotate about pins so as alternately to increase and diminish the distance between two vanes. The driving-pulley is loosely mounted on one vaneshaft and is connected by cranks and rods to the two vane-shafts. Fig. 3 shows one arrangement of rods and cranks for operating two double vanes, and Fig. 4 shows the rods and cranks connecting the pulley to the vane-shafts. The pulley carries a pin r, and the vane-shafts, one of which is hollow, and surrounds the other solid shaft, carry cranks o, p, the pins in which are linked to a rod l pivoted on the pin r, by means of rods i, k. The cranks o, p are so placed that the radius through the axis of the shafts and the pin s bisects the angle between the median line of the vanes. Each quarter revolution thus occupies equal time intervals. At the opposite ends, the vane shafts carry cranks m, n, and links c, d connect one end of each crank to a crank g moving about a pin x fixed on the casing. Opposite ends of the cranks m, n are similarly connected by rods e, f, h, in order to obviate great stresses in the rods, but one set of rods may be dispensed with. With this arrangement of rods, two adjacent vane surfaces approach and recede twice in each revolution. Fig. 11 shows a mechanism for driving two single vanes to give one approach and recession per revolution. The vane-shafts carry single cranks m, n, the outer ends of which are linked by rods c, d, e, f, g, h to a fixed pin x on the casing.
