Title: Improvements relating to manufacture of blading for axial-flow fluid machines
Inventor: KENT NELSON HECTOR
IPC: B21K3/04
Filed: 1955-03-10
Abstract: 811,921. Making turbine and compressor blades. ROLLS-ROYCE Ltd. March 9, 1956 [March 10, 1955], No. 7127/55. Class 83 (2). A method of making a turbine or compressor blade comprises drilling axially-extending passages 11 adjacent the peripheral surface of a slug 10, hot working the slug by extrusion, rolling or forging to elongate the drillings and reduce their cross-sectional area, drilling or machining a central hollow formation 12, Fig. 4, in the hot worked blank leaving material between the drillings and the hollow 12, and pressing the blade portion of the blank to the required aerodynamic shape, Fig. 3 (not shown). The blank is preferably of " Nimonic " (Registered Trade Mark) and has ridges 10a, 10b formed before or during the hot-working operation and corresponding to the leading and trailing edges of the blade. Drill holes 11a, 11b are formed adjacent the ridges. The billet is then preferably hot extruded using glass as a lubricant, an enlarged root portion 15 remaining on the blank. The hollow 12 is then machined in the blank, leaving a blind end 12a, said hollow being tapered so that the cross-sectional area of the remaining blade material decreases from the root end towards the tip. Alternatively the reduction in area may be obtained by hot swaging after forming a central bore of uniform diameter. Material 13, 14 at the ends of the blank is then removed by machining whereby the passages 11<SP>1</SP> emerge laterally of the blank at its root end and axially at its tip end. A slot 12c is then cut near the blind end 12a and the blank is pressed or forged at elevated temperature or low temperature to aerodynamic profile. A filling medium, such as low-melting point metal, may be used during the pressing. The root end 15 is subsequently broached to fir-tree root form 16, Fig. 5a; other forms of root such as bulb root may alternatively be used. The tip end of the blade is then slit and the two tongues 19 thereby formed are folded over and flattened and a reinforcing plate 20 is welded thereto. A drilling 12d is provided for the escape of coolant when the blade is in use. Alternatively, the tongues may be initially folded over to close the ends of the holes 11<SP>1</SP> and subsequently further holes may be drilled through the shroud to connect with the holes 11<SP>1</SP> whereby the cooling gas exhausts above the shroud. Alternatively a separate shroud may be welded to the tip and drillings are then made to enable the cooling gas to exhaust above or below the shroud. The blades may be assembled in a stator or in a turbine rotor disc provided with passages for the supply of cooling air as described in Specification 811,922, [Group XXVI].

Title: Expanded polymer particles and process for their production
IPC: C08J9/16
Filed: 1960-03-03
Abstract: Expanded polymer particles are made by introducing or injecting a polymeric material or suitable starting materials or reactants which are capable of forming such polymeric material, and which polymers or starting materials are, due to their composition or due to the presence of a suitable adjuvant, capable of foaming or expanding at an elevated temperature, into a stream of a hot gas which has a temperature high enough to initiate foaming or expansion of the polymer introduced or formed, and a velocity which is close to or higher than sonic velocity.  The particles so obtained are open and/or closed cell particles of size between 1 and 1,000 microns, and the closed cells may be filled with a gas, such as air, nitrogen, carbon dioxide or helium, or vapour, such as that of acetone or methyl chloride.  The particles may also contain fillers, pigments or finely divided metals, e.g. aluminium flake.  The stream of hot gases may be provided by gas turbines, or the exhaust gases from internal combustion engines, jet, turbojet and rocket motors may be used.  A suitable apparatus comprising a compressor-turbine system is described (see Division B1).  The particles may be separated from the carrier gas as by centrifugal or cyclone separators, bag filters or electrical precipitators, or they may be collected on a layer or coating of adhesive or binder composition.  In examples (i) two liquids, one consisting of a phenol-formaldehyde resin mixed with isopropyl ether and a wetting agent, and the other an aqueous mixture of sulphuric and phosphoric acids, are separately fed into a stream of hot exhaust gases from the compressorturbine system to form a pink smoke-consisting of dispersed cellular particles of phenolic resin; (ii) a black smoke is produced when furfuryl alcohol is added to the resin composition of (i); and (iii) a white smoke is obtained when the components of a polyurethane are injected into the exhaust gases. Other resins mentioned are epoxy, urea-formaldehyde and silicone resins and polyvinyl chloride and polystyrene.  Many uses of the aerosols and the particles per se are given.

Abstract: 635,969. Sound emitting and receiving apparatus. BRUSH DEVELOPMENT CO. March 18, 1946, No. 8304. Convention date, March 19, 1945. [Class 40 (iv)] [Also in Group XL (b)] A piezo-electric crystal comprising an ammonium salt is prevented from decomposition due to rise in temperature by surrounding the crystal with an atmosphere of ammonia gas, the concentration of which increases as the temperature rises. Suitable crystals are primary ammonium phosphate and arsenate, primary ammonium-thallium phosphate, ammonium pentaborate, and ammonium lithium sulphate. The invention is useful in devices such as underwater loudspeakers where the generated energy causes a rise in temperature. Fig. 1 shows a transducer comprising a sealed casing 35 in which an array of crystal elements 37 are mounted between a massive base 38 and a diaphragm 36. The casing contains a bag 48 of a substance which on heating gives off ammonia gas more readily than the crystals 37, such as charcoal, activated alumina or silica gel on which ammonia gas has been adsorbed. Ammonium salts, particularly ammonates, may be used. In a modification (Fig. 4, not shown), the casing of a transducer is charged with ammonia gas under pressure before sealing. Specifications 575,068, [Group XL], and 617,611, [Group XL (c)], are referred to.
