Title: Improvements in turbine blades and their method of manufacture
IPC: B23P15/04
Filed: 1950-05-24
Abstract: 716,105. Turbine blades. STALKER, E. A. May 24, 1950, No. 13018/50. Class 110(3) [Also in Group XXII] A turbine blade has a plurality of slots 20 formed in the leading edge through which a cooling fluid can flow from the hollow interior of the blade, the slots having their ends on either side of the leading edge inclined towards one and the same end of the blade and leading into the concave and convex surfaces of the blade. The slots on either side of the leading edge may be continuous to form slots of crescent or chevron shape. The blade may be formed from a metal blank 40 having a thickened part 42 in which crescentshaped slots 20 are formed, the blank then being folded about the thickened part to form a hollow aerofoil section, the thickened part forming the leading edge thereof. Alternatively, slots 84 may be cut in the thickened leading edge portion of an aerofoil section blank by means of a conicalshaped hollow saw as shown in Fig. 7. The blade is inserted in a root portion 14 and welded thereto. Specifications 652,870, 679,467 and 716,144, are referred to.

Abstract: 1491122 Zone melting furnace SIEMENS AG 27 March 1975 [27 March 1974(2)] 13089/75 Heading ClA [Also in Division Bl] An apparatus for the production of a compound semi-conductor, e.g. Ga, Al or In arsenide, phosphide or sulphide or an alloy comprises as shown in Fig. 1 a cylindrical pressure vessel 2 having a cooling jacket 8 surrounding it and fitted with cooled end covers 4 and 5 and two hollow cylindrical furnaces 20 and 22 with a tubular quartz ampoule 28 arranged therein so that each end of the ampoule is heated by its respective furnace. Gallium 32 is provided in graphite heat 30 heated by induction coil 60, whilst phosphorus 34 is arranged in the end of the ampoule 28. Pusher rod 46 serves to move the ampoule through furnaces 20 and 22 and the induction coil 60 for zonal melting. Inside the pressure vessel 2 is a gas, e.g. nitrogen, whose pressure is adjusted to higher than that in the ampoule. The gas carries off heat from the high temperature zone to the inner wall of the pressure vessel and so establishes a gas cooling circuit represented by the arrow.

IPC: F41A25/02
Abstract: 131,337. Compagnie des Forges et AciÚries de la Marine et d'Homecourt. May 2, 1917, [Convention date]. Recoil apparatus.-Relates to hydro - pneumatic recoil brakes of the kind described in Specification 3145/15. [Class 122 (i), Engine and like cylinders &c.], in which the liquid and gas are separated by a floating diaphram comprising two fluidtight elements separated by a yielding substance and capable of approaching each other. According to the invention, one part of the piston is provided with a retarding-ram to control the run-out movement, and means is provided for replenishing the substance in the chamber between the two elements of the piston. In the form shown, liquid in space 25 and gas under pressure in space 24 are separated by the two-part diaphragm 1, 4, the parts being provided with packing-rings 5, 6. A projection 2 on the portion 1 engages a cavity 21 in the member 4 and the separation of the parts is prevented by a two-part ring 19. The annular space 12 is supplied with plastic packing through a valve 13, and leakage of the packing into the space 21 is prevented by a ring 17. The liquid side of the diaphragm is provided with a shaped projection 22 entering a hole 23 in the brake to control the end of the run-out. The pressure of the liquid and gas on the outside areas of the portions 4, 1 is intensified within the space 12 and serves to maintain a fluid-tight joint in the diaphragm.

The chains of a dumper vehicle or fork-lift truck comprises a rear portion 10 carrying a pair of driven ground-wheels 22 and pivotally supported for lateral tilting from a bridge member 16 connected by a vertical pivot 20 for steering purposes to a front portion 11 carrying a second pair of driven ground-wheels 24. The input shafts of differential axles 21, 23 carrying the wheels 22, 24 are connected by universal couplings 26 and a shaft 25 provided with a spline and coil spring arrangement 27 permitting limited telescopic movement. The input shaft of the axle 21 is driven through chain and sprocket drives 32, 35 and a gearbox 31 by a diesel engine 28. A double-acting steering ram 41 reacting between the front chassis portion 11 and the bridge member 16 is controlled by a valve 44 comprising a valve body carried by the drop arm 39 of a steering column 38 and a control member 47 connected by a link 48 and a ball-joint 39 to the front chassis portion 11. When the valve body is displaced from a neutral position relative to the control member 47 by the drop arm 39 fluid from an engine-driven pump is supplied to the ram 41 through one of pipes 51, 52 to articulate the chassis portions 10, 11 until relative movement therebetween restores the valve to the neutral position. Stops 53 on the bridge member 16 coact with the front chassis portion 11 to limit the articulation of the chassis portions. A skip 43 tippable by a ram 40 is mounted on the front chassis portion 11. The bridge member 16 may extend under, instead of over, the rear chassis portion 10 and the positions of the engine 28 and the skip 43 may be reversed.

IPC: A23J1/16
Abstract: 132,798. Kowalski, M. von Wierusz-. July 11, 1916, [Convention date]. Food for animals.-The process of purifying raw sugar juice by means of sulphurous acid and lime is so modified as to yield a precipitate containing a smaller percentage of inorganic substances than those usually produced, and therefore more fit for use as food for animals. For this purpose, the juice is heated to 80-100‹ C. and treated with sulphur in the usual manner. It is then, without reducing its temperature, treated with lime until it has an alkalinity of 0.02-0.04, and filtered. The process is also applicable to the waste liquors of sugar factories.

Abstract: 137,268. Buffard, C. F. Dec. 28, 1918, [Convention date]. Void [Published under Sect. 91 of the Act]. Compiling statistics mechanically.-Statistics relating to transport services and other commercial transactions are compiled by applying perforated tickets or cards to the apparatus shown in Fig. 7. The tickets 4, perforated in positions corresponding to their values or other data, are placed one at a time upon a chamber 2 provided with a number of pistons 3. The chamber 2 is filled with liquid and is fitted with a spring-controlled plunger 8 and a plunger 9 connected with the totalizing mechanism. Depression of the perforated lid 5 and plunger 8 causes the pistonrods to protrude through the perforations in the ticket and lid and presumably to effect the required actuation of the totalizer. If the number of rods so protruded corresponds with the number for which the apparatus is set, the piston 9 is forced outwardly to an extent sufficient to free the totalizing mechanism which otherwise would be locked against movement.

Title: Improvements in the process of manufacture of solid carbon dioxide
IPC: C01B32/55
Filed: 1929-05-06
Abstract: 333,212. Peggs, K. C. May 6, 1929. Solidifying.-Liquid carbon dioxide &c. is supplied through a valve B into a chamber closed at its other end by a block of solid carbon dioxide &c. formed by the reduction of pressure on previous quantities of the gas. Vapour entering with the liquid is led off by an outlet F. The liquid expands through the block, depositing solid which increases the density of the block. The open end of the chamber is surrounded by a duct D through which gas is withdrawn at a reduced pressure. The pressure moves the block outwards, and its motion may be braked by a brake P controlled by temperature or pressure controlled devices attached to the chamber at points H, J, the pressures or temperatures at these points determining the operation of the brake. Normally the expansion takes place through the block. At starting, a block may he formed by expansion into the chamber at low pressure, or by expansion through a sieve or a screen formed of a mass of granular material or a loosely fitting plate, afterwards remcved. In a modification, Fig. 3, a vessel is provided with closed ends and a screen C on which the block is built up, liquid being introduced at the top and gas escaping at low pressure through an outlet K. A pressure or temperature indicator L at any desired level shows when the solid block reaches that level. The liquefied gas may alternatively be supplied at the bottom, and the screen be located near the top. A pressure or temperature actuated device may cut off the supply of liquid automatically when the vessel is filled or at any desired point.
