Title: Improvements in or relating to compressors of gas turbine engines
Inventor: NIXON FRANK
IPC: F02C7/047
Filed: 1949-08-26
Abstract: 667,981. Centrifugal pumps; gas turbine plant. ROLLS-ROYCE, Ltd. Aug. 25, 1950. [Aug. 26, 1949] No. 22299/49. Classes 110(i) and 110(iii). A distributer for anti-icing liquid is rotatably mounted in the air intake of the compressor of a gas turbine engine, and is supplied at its radially inner portion with the liquid. The liquid, which may be methyl or other alcohol, is fed from, it may be, a tank pressurized by air compressed in the compressor 10 of the engine, and passes by way of pipes 26, 25 and 24 to an annular groove 22 in the hub 20a of the distributer. The liquid passes by way of ports 23 to passages 20c in radially-extending blades 20b, and is ejected through holes 20d. Instead of being uniform, the size of the holes may increase towards the axis of rotation. Alternatively, the holes may be replaced by a tapered slot extending along the leading edge of each blade 20b. The distributer is preferably rotated by the action of the air stream on the blades 20b, which are of aerofoil section. Alternatively, as shown, it is driven from the compressor shaft 10a through a coupling shaft 30 which is splined to a stub shaft 31 carrying a sun wheel 32. The latter meshes with a number of planet wheels 33 carried by the distributer. The planet wheels mesh with an annular gear 36 which is normally free to rotate. The distributer is brought into rotation by bringing the annular gear 36 to rest by means of a multi-plate brake 38 operated by a piston 39 to which pressure fluid is supplied by a pipe 40 and ducts 41 and 42. The fluid supply may be controlled either manually or automatically in accordance with icing conditions. A conical fairing 15 is attached to and rotates with the distributer, but if it is to accommodate a starter motor for the engine it can instead be attached to a fixed support. The starter motor may also drive the distributer, or a separate motor may be provided for this purpose. The compressor may be of the centrifugal type. The gas turbine may drive a propellor, in which case the distrimay be formed by the hub portions of the propellor blades, which portions may be enshrouded by streamlined fairings acting as the distributer blades.

Abstract: 652,073. Frequency measurement. MARCONI INSTRUMENTS, Ltd., and NAPIER & SON, Ltd., D. Aug. 25, 1948, No. 22441. [Class 37] [Also in Group XXXVIII] In a recording speed measuring instrument, Fig. 1, a tachometer generator G produces an A.C. signal whose frequency is proportional to the drive speed, which is limited, squared and differentiated in valves V1, V2, V3, and deflects a galvanometer R1 which records a trace on a moving tape T. A piezo-electric oscillator V4, V41 produces a standard signal at 100 kc/s. which is broken down in multivibrators such as V5, V51 to a 100 c/s. signal which is limited, squared, and differentiated in valves V9, V10 and deflects a galvanometer R2 whose trace is also recorded on the tape. A further multivibrator V8, V81 produces a 10 c/s. signal which is superimposed on the 100 c/s. signal in V9 to enlarge every 10th peak. The two records are comparable by a cursor C which is laterally movable along the tape and pivotable about A. The signals may be displayed on a double beam C.R.O.

Abstract: 1275027 Spot-type disc brakes A TEVES GmbH 19 April 1971 [27 Feb 1970] 22552/71 Heading F2E An "intermediate piece" 1, thicker than a brake pad, is interposed between an actuating appliance (e.g. the piston 4) in one arm 3 of the U-shaped yoke of a floating sliding caliper 8 and the adjacent brake pad 2; the yoke arm 3 has a side opening 5 through which the intermediate piece can be removed, and at least the pad 2 is guided and retained in a relatively-fixed U- shaped brake carrier 13. As shown, the "intermediate piece" 1 has a trapezoidal outline when viewed radially and a rectangular outline when viewed tangentially; it also has a projection co-operating with a groove 6 in piston 4. The piece 1 has an axial length such that when it is slid tangentially out through the opening 5, the caliper 8 may be moved in a direction parallel to the disc axis and to the right as seen in Fig. 1; such movement enables guiding ledges 9 and 10 on the caliper to be disengaged from corresponding guiding ledges 12, 11 on the brake carrier 13. Thereafter, the caliper 8 may be simply lifted off in a radial direction. As shown both brake pads 2 and 17 are accommodated in a cut-away central portion 18 in brake carrier 13 which latter takes the torque; after removal of caliper 8 pads 2, 17 may be repaired or replaced.

Abstract: 442,375. Fusible cut-outs. CRABTREE, J. A., Endwood, Little Aston Park, Sutton Coldfield. Aug. 3, 1934, No. 22622. [Class 38 (i)] A fuse element consists of a sheath of a metal which does not deteriorate in conductivity due to oxidation by heating in air and a core of a metal having a boiling point substantially less than the melting point of the sheath metal or of an alloy of which one of the constituents has such a boiling point. Preferably also the core or one of its constituents has an atomic weight higher than that of the sheath. Suitable materials are silver for the sheath and cadmium or a cadmium-tin alloy for the core. The time of fusing may be controlled by forming the element with an irregular sectional area or by applying local coverings at one or more points. The element may be enclosed in a ceramic container packed with sand and may be provided with an indicator dependent upon the subsequent fusing of a higher-resistance wire connected in parallel. The Provisional Specification refers also to the use of zinc in combination with silver, to the use of silver alloys, and to alternative arrangements in which the materials are arranged in the form of laminµ or as combinations of separate conductors arranged in series or parallel. Specifications 439,432 and 439,517 are referred to.

Title: Improvements in or relating to the manufacture of hydrocyanic acid
IPC: C01C3/02
Filed: 1934-08-13
Abstract: Hydrocyanic acid is obtained by reacting, in the absence of a catalyst, ammonia, a hydrocarbon or mixture of hydrocarbons, and oxygen or air, the hydrocarbon constituent being in excess of the amount stoichiometrically equivalent to the quantity of ammonia present, the heat required for the endothermic reaction between ammonia and hydrocarbon being supplied at least in part by a concurrent exothermic reaction between oxygen and hydrocarbon, and the quantity of oxygen present in the initial mixture being equivalent to a part only of the excess of hydrocarbon.  A part of the necessary heat may be supplied by external heating, say by preheating the reaction mixture to not less than 400 DEG  C., preferably by heat exchange with the exit reaction gases. Suitable reaction temperatures lie between about 1000 and 1500 DEG  C. Preferred proportions of the reacting gases are about one volume of ammonia, a quantity of hydrocarbon or mixture of hydrocarbons equivalent to 2 to 5 volumes of methane and 1 to 3 volumes of oxygen or an equivalent volume of air.  The hydrocarbons which may be employed include methane, natural gas, ethylene, ethane, propane or butane.  Atmospheric or higher or lower pressures may be employed. According to a modification, hydrocarbon, carbon or other carbonaceous material is burnt with air or oxygen to produce a flue gas having a temperature of 400--1000 DEG C., and a mixture of ammonia with an excess of hydrocarbon and sufficient air or oxygen to burn, a part of this excess is introduced into the hot flue gas.  The process may be conducted by passing the mixture of gases through a silica tube heated in an electric furnace.

Title: Improvements in aerial systems employed in wireless signalling
IPC: H01Q21/08
Filed: 1919-09-24
Abstract: 158,927. Franklin, C. S. Sept. 24, 1919. Directive signalling; duplex signalling.-Two or more unidirectional systems of the type described in Specifications 24098/14 and 5783/15 are spaced a fraction of a wave-length apart in the direction of signals to be received. Oscillations in these two systems are combined by phasing circuits with a common receiver. Each system is arranged to give a similar polar curve, and the resulting curve from combining the two systems is better than either taken separately, giving almost complete cancellation behind the station. In an example, Fig. 1, A, B, C, D are four frame aerials erected in the line of communication. A, B are combined through tuned circuits E, F coupled to them. The circuits E, F are mistuned equally but in opposite senses to a degree dependent on the spacing between the aerials, so that waves from one direction along A, D will produce oscillations in them of exactly opposite phase, and waves in the other direction, oscillations of slightly different phase. The circuits C, Dare similarly combined through G, H. The circuits E, F are both coupled to circuit O and the circuits G, H tQ the circuit P, and O, Pare both coupled to the receiving-circuit S. Each of the systems separately has a polar curve showing loops behind the station at 120‹ to the line of communication. In the present invention, circuits 0, P are mistuned equally but in opposite senses to a degree such that waves from this direction will produce in them oscillations of exactly opposite phase and will therefore produce no effect in circuit S. Thus the combined systems give zero reception at 90‹, 120‹ and 180‹ with the line of communication. A method is mentioned in which each of the four frame aerials mentioned above is replaced by two frames at right-angles connected to a radiogoniometer. This is stated to give zero reception in six controllable directions and to be particularly desirable in the case of duplex working.

Abstract: 229,221. Benjamin Electric, Ltd., and Ives, R. A. Oct. 6, 1924. Securing globes and shades to holders. - For securing a globe or shade to the holder of an electric or other lamp, the substantially horizontal lower rim 2 of a conical holder 1 is provided with equally-spaced slots 4 in which one or more independent spring hooks 5 are pivotally mounted. In the form shown in Fig. 1, each hook has an inwardly-bent outer end 6 on the outside of the holder 1 for engaging the upper portion of the globe or shade, a slightly cranked middle portion 5a which pivots about the slot, and on the inside of the holder a substantially flat inner end 7 carrying a detachable spring 8, the free end of which bears against the underside of the rim 2. Spring fingers 1<a> formed on the holder 1 serve to retain in the lower position a movable clamping-ring 3 which covers the hooks 5 and prevents their unintentional outward movement and at the same time serves as a lower extension of the holder 1. In the modification shown in Fig. 6, the hook 10 is made of springy metal, one end being bent inwardly at 11 for engaging the globe or shade and the other end being bent back upon itself at 12 to form an integral spring member 12<a>, and an upwardly bent lug 13 engages the outside of the holder 1. Instead of using three spring hooks, two fixed hooks and one spring hook mav be employed.
