Title: Gas turbine engine
Inventor: BILL ARTHUR
IPC: F02C7/12
Filed: 1964-06-12
Abstract: 1,008,886. Gas turbine jet engines. ROLLSROYCE Ltd. June 12, 1964, No. 24612/64. Headings FIG and F1J. A gas turbine engine comprises compressor equipment, combustion equipment, turbine equipment and an exhaust duct all arranged in series flow, there being means for bleeding compressed air from a stage of the compressor equipment and means for directing it to parts of the engine for cooling purposes, also means for boosting the pressure of the comprsssed air which is then discharged into the gases flowing through the engine downstream of the stage from which it is bled. The exhaust duct is defined between an outer casing member and an inner frusto-conical member, the frusto-conical member being open at its downstream end and. inducing exhaust gases to form a vortex flow therewithin and form a substantially conical region of gases. over which the remaining exhaust gases flow. The engine shown is a gas turbine jet engine and comprises a high pressure turbine 14 and a low pressure turbine 15 mounted on shafts 17 and 18 to drive a high pressure compressor and a low pressure compressor, all respectively, the shafts 17 and 18 being supported at their downstream ends in bearings 20 and 22. Air bled from the compressor equipment flows to space 51, through bores 50 to space 46, thence through bores 45 to space 44, the air flowing adjacent the bearings 20 and 22 to cool them. The air then flows through bores 43 into a space 42 within the shaft 18 defined by members 40, 41. The air then passes through a tubular member 36 secured to the member 40 to the eye 37 of a centrifugal impeller 31. The impeller comprises discs 32, 33 between which are disposed vanes 34a, the disc 32 being secured to the tube 36 for driving purposes. The cooling air is thus discharged from the impeller 31 at increased pressure into the region 28. The turbine exhaust gases discharge through an annular duct defined by the outer wall 23 and a short frusto-conical inner wall 24, a concave wall 27 being secured within the inner wall so that a toroidal flow of exhaust gases is formed downstream of the wall 27 as indicated at 52. The cooling air is discharged from the impeller 31 into this torodial flow, the toroidal flow constituting a virtual extension of the inner frusto-conical wall 24.

Filed: 1964-06-17
Abstract: 1,024,957. Air-jacketed combustion chambers. GENERAL ELECTRIC CO. June 17, 1964 [June 19, 1963], No. 25049/64. Headings F1G and F1L. Gas turbine engine combustion apparatus includes an air-jacketed combustion chamber bounded by a wall 17, Fig. 1, comprising joined sections having apertures 19 and being spaced from each other by strips 27 which define air conduits 28, and by an end wall comprising an inner cone 22 provided with radial louvres 24, and an outer frusto-conical member 23 provided with off-radial louvres 26. Air from a compressor flows through the air jacket, 12 and 21, is introduced into the combustion chamber through the louvres 24 and 26 tangentially to the inner cone 22 and the frusto-conical member 23 respectively and is mixed with fuel from injector 25. The off-radial disposition of louvres 26 ensures that the air flowing therethrough has a radially inward component of velocity sufficient to prevent the fuel-air mixture impinging on the combustion chamber walls prior to ignition. The combustion products are diluted with air flowing through the perforations 19 and the conduits 28 and the resultant mixture flows around a hollow cone 30 to the turbine 13. Hollow guide blades 31 support the cone 30 within a cylindrical extension 11 of the wall 17. Air from the air jacket 12 flows through the guide blades into the interior of the cone 30 to pass through an aperture 32 in the cone apex. A domed cap 33 diverts this air back over the outer surface of the cone towards the roots of the turbine blades 29 which are thus cooled. Additional openings 36 and 40 may be provided in the cone 30 and cap 40 respectively and the closed larger end of cone 30 may have an aperture 41 for supplying cooling air to the rotor or for oil sump seal pressurization.

Title: Method and apparatus for forming calcium silicate products
Inventor: ZINK HAROLD FRANK
IPC: C04B28/18
Filed: 1954-08-30
Abstract: 769,030. Moulding calcium silicate articles. OWENS-ILLINOIS GLASS CO. Aug. 30, 1954, No. 25100/54. Class 87(2). In making insulation pipe coverings, core blocks, roofing tiles, &c. from a calcium silicate mix, which may contain asbestos fibre, an aqueous lime-silica slurry is sucked into a steam-jacketed mould and remains there under heat until self-supporting, the slurry being covered, during heating, by a layer of water under pressure to prevent evaporation. The mould is then cooled, the water pressure is released and the article ejected to be finally hardened out of the mould. In making a pipe covering the mould comprises a cylinder 10 surrounded by a heating or cooling chamber 15 and having mounted concentrically within it a hollow core 45. A collar around the core 45 forms a piston 30 which is vertically reciprocated by air pressure in air motor 33. A cover 55 is removably attached to chamber 15 and has a baffle plate 56 mounted beneath inlet 68. In operation, the mould 10 and core 45 are first preheated by admitting steam to chamber 15 via pipes 20 and to core 45 via pipe 48. The piston 30 is then in the position "A" of Fig. 4 and a funnel 87 containing the slurry is mounted over mould 10 and piston 30 moves down to draw the slurry into the annular space between mould 10 and core 45. When the mould is filled, fingers 91 which oscillate vertically and rotate about a vertical axis, are lowered into the slurry to remove air bubbles. The cover 55 is then locked in position on the outside of chamber 15 and valve 69 opened to let water under pressure into chamber 57. After a short application of pressure, valve 81 on air line 80 is opened to increase the pressure of the water on the slurry. When the slurry is hard enough to be self-supporting the steam supply to chamber 15 and core 45 is cut off and cooling fluid admitted through pipes 23 to chamber 15, and through pipe 48 to core 45, valve 49 being closed to prevent fluid entering steam pipe 50. When the hardened slurry has reached a temperature less than 212‹F. the water-air pressure in chamber 57 is cut off and valve 71 opened to the atmosphere so that the cover 55 may be removed. The piston 30 then moves up to eject the partly hardened article. Meanwhile the cooling fluid to chamber 15 and core 45 is cut off and steam re-admitted to preheat them ready for the next cycle. Specification 658,427 is referred to.

A helical portion of a resistive layer deposited on a blank 1 is removed by the focused energy of a continuous output laser. The resistive layer may consist of carbon or a nickel chromium alloy on a ceramic support. In the apparatus shown, each resistor blank 1 is supplied by compressed air through a flexible tube 5 to chucks 13, 14 which grip terminal caps 4 and are carried on a slide 8. At least one of the chucks is then rotated and the slide simultaneously moved by mechanism 18. A bridge 31 monitors the resistance value and, when required, a device 32 stops the process, removes the resistor from the chucks and feeds in a fresh blank. The process may be stopped by defocusing the laser output 30, tilting a mirror 28 which may be provided in the optical path, switching off the laser power supply, intercepting the beam with an opaque screen or Kerr cell, or, in another construction, by moving the chucks and the blank out of the beam. The laser 20 consists of a closed discharge tube 22 having platinum electrodes 23, 24 and filled with a gas mixture of carbon dioxide nitrogen and at least one of the gases water vapour and helium. The radiation, at a wavelength of 10À6 microns and with a power exceeding 1 watt, is emitted as parallel beam 21 and focused by a lens 29. A plane partially reflecting mirror 26 and a concave mirror 25 form the laser resonator.

A shearing device comprises a drum rotatable about an axis and provided with circumferentially spaced transverse slots, a cutter head rotatable about an axis normal to the drum axis and having a pair of resilient shear blades which are adapted to pass successively through the slots in the drum, means for rotating the cutter head about its axis and a mechanical linkage between the head and the drum whereby the drum is rotatable from the head. The shearing device is for cutting sheets of metal foil which are adhesively applied to a glass ribbon in the manufacture of capacitors. A cutter head 23, Fig. 2, carried on a motor-driven shaft 20 is provided with three equally spaced sets of shearing blades 24, 25 which are adapted successively to enter slots 32 in a drum 31 carried on a shaft 30 driven from the shaft 20 through gears 27, 42 and a worm 41 and worm wheel 33. The drum 31 has a ribbon of metal foil 60 issuing from a spool 61, Fig. 1, fed thereover. Such foil is notched to form uniformly spaced sheets 47 which are retained on the drum 31 by suction means and expelled when desired by pressure means. The material between the sheets 47 is disposed of through a suction duct 62 and foil fragments are removed from the shearing blades by means of brushes 64, 65. Any surplus material connecting the sheets 47 may be subsequently sheared off by means of shearing rollers. An adhesively coated glass ribbon 70 issuing from a spool 71 is trained about idler pulleys 72, 73 and over an electrically heated pulley 74 about the surface region of the drum 31 already occupied by metal foil sheets 47 so that such sheets become adhesively attached to the ribbon 70. The ribbon 70 is then trained over idler pulleys 76, 77 before being wound on a spool 80. To protect the opposite surfaces of the ribbon 70, both before and after having been provided with metal foil sheets, a paper ribbon 110, Fig. 1, is coiled between the glass ribbon layers on spool 71. The ribbon 110 is transferred from spool 71 to spool 80 via a slack takeup assembly 111 and pulleys 112 to 117. U.S.A. Specification 2,526,703 is referred to.

Abstract: 744,706. Controlling clutches. ROVER CO., Ltd. Aug. 3, 1954 [Sept. 14, 1953], No. 25324/53. Class 80(2) A normally-open switch 12, Fig. 1, is automatically closed during a gear change on a motor vehicle to complete a circuit through a solenoid 10 operating the valve of a fluid-pressure servomotor to disengage a clutch interposed either between the engine and the gearbox or between the gearbox and the road wheels, and a normally-open switch 14 is automatically closed if the speed of the clutch driving member falls, while the clutch is disengaged, below the speed of the clutch driven member to complete a circuit, ioncluding the switch 12, through a solenoid 13 to open the engine throttle. either directly or through a servomotor, independently of the throttle pedal. The switch 12 may be operated by a movable knob on a manual gear lever, but the gear may be operated automatically in accordance with engine speed or load. The switch 14 may be operated by a differential gear connected across the clutch, by a member having limited angular movement relative to one clutch member and in frictional engagement with the other member, by the pressure differential between two pumps, or by a single pump which generates pressure only when there is a difference of speed between the clutch driving and driven members. A further switch, which is opened only when a gear is engaged, may be arranged in series with the switch 12, so that the clutch will re-engage as soon as a gear has been engaged even if the gear lever knob is not released. Fig. 3 shows such an arrangement for a four-speed gear in which the gear lever is moved in one direction for first and third gears and in the opposite direction for second and fourth gears, the switch 12 being replaced by a normally-open two-way switch 15 while normally-closed switches 18 and 19 are opened automatically by engagement of first or third gears and second or fourth gears respectively. In Fig. 3, also, the clutch is engaged by energization of a winding 21 through a normally-closed relay switch 22 which is opened by the solenoid 10 when the latter is energized. Specification 715,746 is referred to.
