Abstract: 677,274. Gas turbines. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 22, 1949 [Nov. 27, 1948], No. 29914/49. Class 110(iii) A nozzle ring assembly for a high temperature gas turbine comprises two concentric radially-spaced blade support rings 77, 78 having circumferentially-spaced openings, and a plurality of nozzles blades 74 having root and tip portions 76 loosely disposed in the openings which are of substantially the same shape as the co-operating parts of the blades. The openings have projecting portions 85, 85a extending around their peripheries to close the small clearance spaces 84, 84a to prevent leakage of fluid therethrough, the size of the projecting portions being so small that thermal expansion during operation of the turbine will result in some crushing of the projecting portions without imposing excessive stresses on the blades or rings. The blade support rings are formed of segments with clearances between each to allow for expansion, and locking rings 80, 80a fit into circumferential grooves to allow a limited movement of the blades in a radial direction. The outer blade support ring 78 is located circumferentially by means of radially-disposed dowel pins 83 fitted in the main frame ring 38 which engage in notches formed in the axially-extending flange 78c of the support ring. The inner blade support ring is located by means of small dowel pins 77a. The turbine casing comprises rings 38, 42 bolted together which are cooled by water flowing through the passages 42d, 42e and which are provided with heat insulation pads 92, 99. The main frame ring 16 which carries a shaft bearing 15 is protected from heat by a cooling pad 59 having concentric grooves 59a at one side to form a radiating surface. The pad is cooled by water flowing through the passages 60, 59b, 62 and 61. The nozzle blades are cooled by air flowing from the annular passage between the combustion chamber casing 22 and the frame tube 26, through the opening 71c in the outer nozzle casing member 71, through the hollow nozzle blades whence it passes through the clearance between the inner nozzle casing member 65 and the blade support ring 77 into the flow of combustion gases. High pressure air is supplied through a pipe 33a to the annular chamber 33 from which part flows through the labyrinth seal 31 to prevent leakage of hot gases, and part flows through the labyrinth seal 30 to prevent leakage of oil from the bearing 15. The exhaust gases pass through a passage formed by walls 52, 53 in which are disposed guide vanes 53, 54a for straightening the flow of gases or for directing the gases on to further rotor blades. Specification 608,476 is referred to. Reference has been directed by the Comptroller to Specifccation 582,152.

Title: Improvements in or relating to methods of and devices for the production of covers for containers, particularly of conserve containers
IPC: B21D51/44
Filed: 1938-10-17
Abstract: 520,251. Making covers for conserve &c. containers. BUHLER BROS. Oct. 17, 1938, No. 30012. Convention date, Oct. 18, 1937. [Classes 83 (ii) and 83 (iv)] Angular bending; twisting wires together; soldering.-In producing covers, for conserve &c. containers, comprising an outer cover rim and an inner plain cover body providing between them a rip-wire, the portion for the rip-wire carrying the necessary solder or solder provided with flux is automatically severed from wire stock, one end is formed into a looped handle and the rest into an annular insert, the parts are assembled and the joint heated to effect soldering and then cooled by an airblast. Wire from a roll 1 passes through a straightening device 4, and through a bath 8 of soldering flux prior to passing through an orifice 10 where the wire is wrapped in soldering-foil fed from a roll 7. The wire is fed by feed rollers 5 continuously driven from a shaft 12 and by intermittently operating rollers 14, 15 also driven from the shaft 12. The rollers 14, 15 feed the wire along one of a number of longitudinal grooves in the periphery of a roller 23 which is rotated step by step. When the end of the wire reaches electric contacts 20 beyond the end of the roller current is supplied to a solenoid 18 to move roller 15 and so interrupt the feed of wire, the length within the groove being severed by a device 26. The'severed lengths are subsequently moved by a slide 27 into a mandrel 29 having a central bore. The forward end of the wire projects beyond the mandrel and between shaping members 34, 35 and 36. The member 34 moves downwardly to bend the wire into a semicircle and then the member 35 moves around to the position shown in Fig. 9 to complete the wire loop, the ends being then twisted together by a rotation of the mandrel. All the movements of the various parts are controlled by means of a series of cams 28 on the shaft 12. The loop 3a forms the handle of the rip wire. A plunger is now operated to move the loop downwardly from the shaping member 34 on to a member 53 where it is gripped by spring claws 51. The remainder of the length of wire is formed into a ring by being wound into a helical groove 61 on the outside of a rotary disc 60 surrounded by an annular stop member 62. The apparatus includes a number of rotatable heads mounted around a turntable so that each are stopped for an interval at each of a number of work stations. As the table rotates, a cover rim 68 of a can is sprayed internally with soldering-flux, a wire ring formed as described above is inserted within the rim, and the interior again sprayed with solder, a cover 84 has its outer flange sprayed externally with flux and is then inserted within the rim, and the flange pressed outwardly so that the wire is tightly gripped between the cover rim 68 and the flange and the assembly is then heated to effect the soldering of the joint.

Title: Improvements in and relating to the production of threads of thermoplastic cellulosederivatives
IPC: D01F2/28
Filed: 1947-11-12
Abstract: <PICT:0633187/IV (a)/1> High tenacity threads of thermoplastic cellulose derivatives suitable for weaving are produced by heating the pre-formed threads to a temperature sufficient to render them plastic, stretching the threads at least 50 per cent while they are in the heated plastic state, and then permitting the threads to shrink at least 8 per cent while they are in a heated plastic state, the plasticity of the thread during both the stretching and shrinking steps being effected solely by the action of heat.  The thermoplastic cellulose derivative may be cellulose acetate, in which case a temperature of 210 DEG  to 360 DEG  C. may be used.  The stretching and shrinking steps may be effected in two stages; the range for the first stretching operation may be 40 to 150 per cent and that for the second stretching may be 20 to 150 per cent.  The threads are preferably shrunk 10 to 20 per cent.  The Figure shows an apparatus which may be used in the process of the invention, in which four rotating rollers are provided of such diameters and speeds that the thread is stretched as it passes through heating tubes 1 and 2 and shrunk as it passes through heating tube 3. Cellulose acetate thread 8, drawn from a bobbin 9 is passed twice round roller 4, down heating tube 1, round roller 5, down heating tube 2 and round roller 6; thence it passes down heating tube 3, round roller 7 and after an extended travel through the air is collected on bobbin 27.  Instead of using a continuous process, the thread from wheel 5 may be collected and subsequently reheated and shrunk, or restretched and then shrunk.
