Title: Improvements in gas turbine installations
IPC: F01D5/14
Filed: 1957-11-18
Abstract: 868,788. Coating with metals. POUIT, R. Nov. 18, 1957 [Nov. 20, 1956], No. 35879/57. Class 82(2) [Also in Group XXVI] In a gas turbine engine, at least one row of stator or rotor blades comprises blades having internal ducts for the passage of cooling fluid, each blade comprising a core formed of light metal or alloy having a relatively high coefficient of thermal conductivity, those surfaces of the blade which are exposed to the hot gas stream being protected by an adherent metallic surface layer having a coefficient of thermal conductivity which is appreciably less than that of the light metal or alloy forming the core of the blade. The invention is shown applied to turbine rotor blades which are mounted on a rotor disc 3, each blade comprising a core 4 provided with cooling fluid ducts 5 and an outer layer 6, cooling fluid such as air from a compressor driven by the turbine being supplied through duct 7 in the shaft and ducts 8 in the rotor disc to the ducts 5 in the blades. The core 4 may be a light alloy of aluminium or magnesium or of both of these metals, and the surface layer 6 may be a nickel base alloy. The core may be formed of a sintered complex of aluminium and alumina which has a very good thermal conductivity and low specific gravity. The outer layer 6 may be formed by a simple plating process for example by electrolysis, but is preferably formed so as to be secured to the blade core by metallic interdiffusion. The layer 6 may be applied in the form of a metallic compound such as a nickel salt which is acted on by suitable reactants, for example alkaline hypophosphites which ensures a deposition of protective metal and also the chemical formation of stable subjacent layers comprising nickel phosphites or phosphates which are poor heat conductors. The blade may be of aluminium and the surface layer produced by surface oxidation of the core. In another embodiment, the core of the blade is treated with a reactant which forms with the basic metal of the core (or at least one of its compounds in the case of an alloy) a compound of this basic metal which has a poorer conductivity than the basic metal or alloy proper, for example an oxide of the basic metals (or of at least one of its compounds in the case of an alloy) which is stable and adherant. The layer may be formed by the reaction of a suitable metalloid, for example phosphorous with the basic metal of the core.

Title: Plants for the electro-slag refining of metals
IPC: H05B7/152
Filed: 1972-08-01
Abstract: 1400284 Electroslag casting processes; continuous casting BOHLER & CO A G Gebr 1 Aug 1972 [17 Sept 1971] 35941/72 Heading B3F [Also in Division G3] In an electroslag refining plant, current is separately supplied to each of a plurality of consumable electrodes. When the current through each electrode has fallen below a respective predetermined value, the position of a common electrode holder relative to a mould is automatically adjusted. As shown, three cylindrical steel electrodes 10 penetrate a slag layer 60 in a water-cooled mould 20. A molten pool 31 forms on top of a solid ingot 30 supported by a copper plate 40. An electrode holder 11 and the mould 20 are supported by vertically movable carriages 12, 23 controlled by lifting gear 13, 24. In use, each electrode is connected to one phase of a threephase supply R, S, T, the neutral line M being connected to plate 40. The current in each phase flows through an ammeter 71 with contacts 71<SP>1</SP> which close if the current falls to a preset value. This value may be different for each phase and may be proportional to the cross-sectional area of the corresponding electrode 10. When all the contact sets 71<SP>1</SP> have closed, current flows through pulsed relays 73, 76 to energize further relays 16, 27 which connect supplies to motors driving lifting gear 13, 24. This action causes stepwise lowering of the electrodes and stepwise raising of the mould in a preset ratio. Relays 73, 76 may be bypassed by switches 74, 77 to allow rapid carriage movement. There may be a plurality of moulds secured to the same holder.

Title: Improvements in or relating to pressure relief devices
IPC: B60G17/04
Filed: 1934-12-17
Abstract: 434,257. Valves. SOC. D'EXPLOITATION DES BREVETS L. SIMON (AMORTISSEURS SANCHOK) SOC. ANON., 9, Rue Boissy d'Anglas, Paris. Dec. 17, 1934, No. 36184. Convention date, June 2. [Class 135] [See also Group XXXII] Relates to a pressure relief device for the shock-absorbers of vehicle suspensions or stationary plants of the kind wherein the shock - absorbers are adjusted by the pressure of a liquid fed thereto through pipes connected with the delivery conduit of a pump, the liquid-pressure in the return conduit of which is controlled by the relief device which comprises co-operating, relatively-movable members spring- pressed towards each other so as to close a passage in one of the members, and co-operating relief surfaces carried by the members. According to the invention the relief surfaces are formed so as to reduce the flow of liquid through the apertured member when the members are moved relatively to each other on increase of liquid pressure. As shown, the pump 26, Fig. 6, is driven for example through flexible shafting from the gear-box of a vehicle and draws oil through a filter 30 and conduit 29 from the reservoir 22 and discharges it into a conduit 33 connected with pipes 31 leading to the shock-absorbers and with a return conduit 1 controlled by the relief device. Initially, the oil leaks through a slot 17, Fig. 1, in a nut 15 on a hollow plug 7 into a chamber Z in a sleeve 2 and through relief surfaces or recesses 7<1> and orifices 4 back into the reservoir until the liquid pressure in the system rises and the plug 7 is moved against the action of a spring 8 and gradually decreases the flow through the recesses 71. The plug 7 and sleeve 2 form the co-operating members of the relief device. If the pressure rises sufficiently, the end of a valve-member 10 slidable in the plug engages a stop 20 mounted in the sleeve while the plug moves relatively thereto and the oil escapes through the valve-apertures 11 in order to stabilize the pressure. The ultimate pressure can be varied by manually adjusting the position of the stop 20 and the pressure of the spring 8 through a cap 5.

Abstract: 364,299. Totalizators. ERICSSON TELEPHONES, Ltd., 67, Kingsway, London, WILMAN, C. W., 7, Grange Avenue, SMITH, L. W., 9, Meadow Road, and LYDEN, T., Peveril Road, all in Beeston, Nottinghamshire. Dec. 11, 1930, No. 37327. [Class 106 (i).] Bets may be cancelled by sending one or more signals to absorb or nullify one or more subsequent registering signals. Fig. 1 shows an arrangement for enabling one bet only to be cancelled. The registering (or transferring) signal arrives at the register R via line 1 and contacts al, bl but if a cancel signal is sent over line 2, relay B is operated and locks up at a2, b2, and consequently the registering circuit is broken at bl and the line 1 connected up with a relay A. The next bet signal will therefore energize this relay to bring down relay B at a2 and restore the lines to normal. In the form shown in Fig. 2, a bet signal on line 1 energizes a relay C to complete at cl a line through switches F, G to the register at R. If a cancel signal is sent relay E is energized to operate at el the magnet GDM of switch G and thus put wipers f1, g1 out of step. If the next signal should be a registering signal the operation of contact cl completes a line through a relay D in series with the register which however cannot now operate. Contact d1 causes action of magnet FDM and switch F steps to restore agreement between the switches. If two or more cancel signals are received in succession, switch G will advance correspondingly and the registering circuits cannot be effective until a similar number of bets have been received and absorbed. When switch G has advanced until one step short of agreement again a relay H is energized through the wipers f2, g2 to break the cancel line at h1. Wipers f3, g3 control lamps L1, L2, to indicate the relative positions of the two switches and thus enable the number of outstanding cancellations to be determined. Specification 341,991 is referred to.
