Title: Improvements in Gas Turbine Blade Cooling
Inventor: MOORE ALAN
IPC: F01D5/08
Filed: 1966-05-18
Abstract: 1,152,331. Gas turbine engines; axial-flow compressors. ROLLS-ROYCE Ltd. May 17, 1967 [May 18, 1966], No.22055/66. Headings F1C, F1G and F1T. In a gas turbine, coolant air under pressure is received by a chamber between nozzle blade structure and a rotor disc and is then circulated within the rotor blades for cooling, an annular wall portion of the rotor disc defining with an annular wall portion of the nozzle blade structure a gap through which coolant air can bleed into the main gas stream, the rotor disc wall portion extending to a different diameter from the other wall portion and thereby projecting into the path of the main gas stream so that a part of the dynamic pressure of the main gas stream is used to resist flow of coolant air from the chamber through the gap. The first-stage turbine blades 26, Figs.1  and 2, of a gas turbine engine are cooled by air bled from the compressor 10 and passing via a passage 17 and a chamber 20 into a ring of separate axial cavities 40 disposed in the rotor disc 21 and having inlet openings 41 in the upstream face of the disc. The cooling air then flows through passages 38 formed in the blades 26. The blade platforms 37 project into the working fluid passage of the turbine; whereby gas impinges on the lip 44 formed by the upstream edges of the platforms and consequently has at least a part of its kinetic energy converted into pressure energy. The resultant increase in the pressure of the gas in the vicinity of the lip 44 reduces the flow of air into the working fluid passage via the gap between the lip 44 and a lip 43 formed on the inlet nozzle vanes 45 and reduces the pressure drop suffered by the air so that its pressure at the inlets 41 is sufficient for the required blade cooling. A baffle 46 may be provided to hinder any local recirculation of gas into the chamber 20. The lip 43 may be inclined radially inwards to increase the effective radial projection into the working fluid passage of the opposing formation 44 which in this case is a plain flat wall. Cooling air also flows inwardly between bosses 33 and is deflected around the hub of rotor disc 21 by a hub shield 35, dividing into two streams flowing outwardly through clearances in couplings 30 and along opposed faces of stator structure 31 and finally escaping into the working fluid passage. Lips 47, 48 similar to the lips 43, 44 raise the air pressure in passage 51 so that it is higher than the air pressure in passage 52 instead of being lower, the pressure difference between the two passages being, however, reduced so that there is less leakage through a seal 32. The increased air pressure exerted on the upstream faces of the discs 21, 27 assists in balancing the end thrust of the compressor 10. The surfaces of the rotor blades which are impinged upon by the main gas flow may be formed of air-permeable material and arranged for the diffusion of air from the coolant passages through the permeable material.

Abstract: 1,243,112. Treating ores. CANADIAN PATENTS & DEVELOPMENT Ltd. 30 April, 1969 [7 June, 1968], No. 22132/69. Heading B2H. Siliceous and/or phosphatic materials are separated from iron ore by forming an aqueous mixture containing the ore in particulate form, a surface active conditioning agent consisting of a sulphonic acid, a fatty acid and/or a water soluble salt thereof, and a hydrocarbon oil, agitating the mixture to form an agglomerate oil phase and a residual aqueous phase, one of the phases being rich in iron and the other in siliceous and/or phosphatic material, and separating the phases. The pH of the mixture may, if necessary, be adjusted so that such phases are formed. The ore may be finely ground either before or during mixing with water. Specified conditioning agents are oleic acid, linoleic acid, tall oil and their soluble alkali metal or ammonium salts. An amine conditioner, e.g. one derived from pine resin acid, may he employed in small amounts along with sulphonic or fatty acid.

A grinding system, particularly for cement, is controlled by determining the circulation figure C which equals S/F where S is a separator fed and F the fire fraction from the separator, per unit time. The separator feed or fine or course fractions are determined by at least two radioactive type detectors, and the signals combined to give C. The system comprises a tube mill I fed by a weighing band the output being supplied via an elevator 4 to a separator 5. Measurement of S takes place at 10. Coarse material is recirculated at G. Fines are measured at 11. The mill is dedusted via a pipe 7, and dustfraction E after precipitation in an electro-filter 8 is mixed with the fraction F. A screw 12 takes a small sample to a specific surface meter 13. The separator 5 is controlled by adjustable louvre dampers to maintain an optimum value of C, in response to the signals derived at 10, 11 and the meter 13 signal (which is representative of fineness) controls the fresh feed rate P.

Abstract: 643,250. Cables. TELEGRAPH CONSTRUCTION & MAINTENANCE CO., Ltd. Aug. 31, 1948, No. 22963. [Class 36] In a high-frequency cable of the type in which an inner conductor A is surrounded by cellular insulation B, the inner conductor is constructed so as to be extensible when subjected to longitudinal strain. The inner conductor may include non-extensible portions which are connected together by extensible portions. The extensible parts of the conductor may be given a sinuous or zig-zag form, or may be coiled into a helix 3. The application of longitudinal strain causes the crimped portions of the conductor to straighten out until the strain is removed. When the dielectric, which may be expanded polyethylene, is applied by extrusion, the conductor may be passed through a crimping device immediately before entering the extrusion machine. The cable may be completed by the application of an outer conductor or screen and an outer sheath. Specification 629,668, [Group IV (a)], is referred to.
