Patent GB-123624-A (GB)
Title: Improvements in or relating to Steam Turbines.
IPC: F01D17/18
Filed: 1918-03-25
Abstract: 123,624. Brown & Co., J., and Wood, W. H. March 25, 1918. Regulating.-Multi-stage turbines are provided with an arrangement of inter-stage valves and bypasses adapted to minimise the variation in pressure drop over the respective stages under varying conditions of working, the nozzle area for passage of steam from a higher stage to the next succeeding lower stage being varied according to the supply of steam from the higher to the lower stage. The steam chest connects with control valves C, H, Q, T, e, o, p, q, Fig. 1, which are opened in the order named for increasing power. For lowest power, steam from the valve C flows through the stages 1, 2, 3, 4 in series by way of nozzles D, E, F, G. For higher power, the valve H is opened, and, being geared to a valve N, moves the same so as to open additional nozzle openings P leading to stage 2. Further increase of power is obtained by opening the valve Q, which admits steam to a by-pass R and nozzles S, Figs. 3 and 5, leading to the stage 2. By opening the other valves specified above, additional nozzle openings and/or by-passes are brought into operation; for example, the first two or three stages may work in parallel with highpressure steam. Fig. 6 shows means for interconnecting the valves; thus, the valve H is actuated by a spur gear I operated by a spindle J serving to move a nut K and through a bellcrank K<1> to actuate a rack L, which in turn, through gearing M and another rack, moves the slide valve N.

Title: High temperature composite gas turbine engine components
IPC: F01D17/08
Filed: 1968-02-01
Abstract: 1,143,917. Making metal powder; turbine blades; thermocouples; brazing. GENERAL MOTORS CORP. 1 Feb., 1968 [5 May, 1967], No. 5230/68. Headings B3A and B3R. [Also in Divisions F1 and H1] Nickel aluminide having substantially equal atomic proportions of nickel and aluminium and for use in composite gas turbine engine components such as blades and thermocouple probes is prepared in the following manner:- stock of high purity nickel (99À99% by weight) is melted in a crucible at 2800‹ F. and at a pressure of 4 x 10<SP>-4</SP> Torr. by induction heating. The induction heating furnace is back filled with argon to a pressure of 5 1b./inch<SP>2</SP> gauge and aluminium of 99À99% purity is added to the melted nickel in the stoichiometric quantity from a hopper. The melt is contained in the crucible until all signs of exothermic reaction have subsided and is then poured into a copper chill mould in an argon atmosphere. The cast ingot of nickel aluminide is broken into fragments for further size reduction in a jaw crusher, the product of which is ball milled in toluene with aluminium oxide balls to between 1 and 10 micron particle size. The toluene is evaporated at 125‹ F to produce a powder containing 68À3-69À5% by weight nickel and the balance aluminium and traces of other elements. The powder is hot pressed in a vacuum of 1 x 10<SP>-4</SP> Torr. in graphite dies and sintered at 2850‹ F. for 15 minutes under 6000 lb./inch<SP>2</SP> pressure. A composite turbine blade (20), Figs. 2, 3 (not shown), is constructed by brazing leading and/or trailing edge portions (34, 36) of nickel aluminide formed by the above method to a nickel-based alloy body portion (42) containing molybdenum, chromium, aluminium, titanium and niobium in specified proportions. The brazing cycle is carried out in a vacuum of less than 1 x 10<SP>-4</SP> Torr. at 2200‹F. for 2 minutes using a nickel-based brazing alloy in powder form containing 16% by weight tungsten, and 1-2% silicon. A composite thermocouple probe for a gas tubine engine, Fig. 4 (not shown), is also constructed by brazing a nickel aluminide tip (54) to a nickelbased alloy sheath (56).

Abstract: 181,780. Lindberg, O. H., and North Eastern Railway Co. Feb. 19, 1921. Skid.-A skid or shoe adapted to be placed temporarily on the rails of railways to bring rolling stock to rest gradually comprises a tongue and a stop member, the tongue being adapted to be mounted by a wheel of a truck or the like and the stop member to prevent further travel of the wheel along or over the skid or shoe. Fig. 1 shows a skid comprising a flanged body portion 1, a tongue 2, a stop member 3, an upwardly inclined heel-piece 4, and a handle 5. The edges 7 of the side flanges 6 of the body 1 are curved or inclined upwardly to facilitate the passage of the skid over facing points. The forward end of the body plate 1 is bent upward to form a raised platform 1<a>. The tongue 2 may fit below the platform, and its upper surface is inclined. The tongue may consist of a leaf of a coach or wagon spring. The stop member 3 has an inclined face 3a, and carries a contact plate 3<c> which is pivoted so that it may adapt itself to the wheel which engages it. The handle 5 is formed separately and may consist of a bent bar fitting into a socket 5a and fastened to the heel-piece 4. Insulating material may be employed to prevent conduction of heat to the handle. In order that the wheel may roll back off the skid when the truck has been stopped, the parts of the skid are so arranged that the part of the wheel vertically below the centre is either unsupported or supported on an inclined plane while the skid is being carried forward by the momentum of the truck.

Title: Improvements in and relating to thread control mechanism for sewing machines
IPC: D05B49/04
Filed: 1941-05-12
Abstract: 549,966. Sewing-machines. UNION SPECIAL MACHINE CO. May 12, 1941. No. 6108. Convention date, Dec. 9, 1940. [Class 112] A rotary take-up 70, Figs, 2 and 8, is mounted on a shaft 71 above the main shaft 16 and to one side of the axis of the needle bar and driven from the' shaft 16 by equal gear wheels 75, 76. The take-up comprises a flanged disc with a threadengaging lug 80. The thread passes from the tension device 90 round a fixed guide 120 to the take-up and back to a fixed guide 123. It passes between two stationary plates 77, 78. The plate 77 lies within the take-up flange, and is secured to the plate 78 by a part 82 which provides a rest for the thread between the guides 120, 123 when it is not engaged by the take-up lug 80. The plate 77 is formed with cam edge 81 which holds the thread off laterally so that the lug 80 in its counterclockwise rotation, as seen in Fig. 8, can at the first stitch pass under the first part of the needle-thread. The lug 80 catches the thread between the part 82 and the guide 123 and commences its take-up action. The thread is paid out as the lug 80 returns toward the cam edge 81. In a modification, the face of the flange of the take-up has an annular groove which is entered by a stationary plate having an edge which forces the thread off the lug 80 as soon as the take-up action is completed. The thread tension comprises a pair of discs 102, Fig. 13, loose on a hollow spindle 96. A thread check spring 114 is coiled round the spindle and its strength can be varied by rotation of the spindle which is fixed in place by a screw 98. The base 91 of the device is socketed into the face-plate 7 and is secured in an angularly adjustable position by a screw 95 and an arcuate slot. The tension is released by a cam-surface on the presser-bar which actuates a rod 117 one end of which bears on the cross washer 105. The rotary-hook shaft is driven at twice the speed of the needle-shaft through spur gearing between it and a lower shaft. The lower shaft is geared by equal wheels and an idler wheel with the top main shaft. The lower pinion of each gear dips into oil held in small local reservoirs. Specification 413,120 is referred to.
