Abstract: 1,161,297. Turbine rotors. GENERAL MOTORS CORP. Aug.24, 1967 [Dec. 19, 1966], No.38971/67. Heading F1T. Blades 14 are retained on a gas turbine or like rotor 7 by the sliding engagement of the root portions of the blades in aerofoil shaped holes 17 passing through the rotor rim 10 and by two circumferentially extending locking rings 33, 34 passing through holes 31, 32 in the blade roots and engaging grooves 35, 36 in the rim 10. Annular cover plates 41, 42 bolted to the faces of the rotor 7 have lugs (91, 92, Fig. 4, not shown), which engage gaps (38) in the respective rings 33, 34 to prevent circumferential movement of the rings. The upstream plate 41 is ribbed at 47 to define passages 49 for the flow of cooling air from a pipe 51 to an annular chamber 59. A portion of this air flows from chamber 59 through ports 65 to an annular chamber 66 defined between the rim 10 and a thin sheet metal ring 62 welded to the rim. Projections 61 on the ring 62 or rim 10 assist cooling as the air flows from chamber 66 to exhaust through ports 67 in the ring 62 adjacent the blade trailing edges. Leakage of air is prevented by continuous lands 68 around the aerofoil holes 17. A further portion of the air flows from chamber 59 through passages 60 in the rim 10 to enter the interiors of the blades 14 through gaps 24 between the two parts 21, 21' of root blocks mounted within the blades. Each blade comprises a liner 19 around which is wrapped an outer skin 18 spaced therefrom by projections 71 to form passages 85. The tip of the liner 19 is closed (at 77, Fig. 2, not shown), so that the cooling air entering the liner through gap 24 flows through radially spaced holes 78 at the leading edge of the liner to impinge upon the skin 18 before flowing rearwardly through passages 85 to exit through slots 82 at the blade trailing edge. The tip of the skin 18 is open so that some air from passages 85 exhausts through the tip past radial ribs (73) on the skin. Holes corresponding to 78 may also be provided in the liner 19 adjacent the trailing edge.

Title: Liquified gas conversion systems
IPC: F17C9/02
Filed: 1960-11-17
Abstract: 897,274. Revaporizing liquefied gases; forcing liquids by gaseous pressure. BENDIX CORPORATION. Nov. 17, 1960 [Dec. 14, 1959], No. 39570/60. Classes 8(2) and 102(2). Revaporization of a mixture of liquefied gases e.g., crude liquid oxygen contaminated with carbon dioxide and hydrocarbon is effected by forcing the liquid from a storage vessel 10 through lines 15, 82 and 91 into a vaporizing cylinder 88 maintained by external means e.g., warm air at a temperature sufficient to vaporize the oxygen content of the liquid, feeding the oxygen vapour through a line 96 heated to a temperature above the boiling point of the least volatile component of the unvaporized portion of the crude liquid oxygen and adding the latter to the so-warmed pure oxygen vapour in a mixing chamber 95 and thereafter feeding the mixture of vapours through a main supply line 105 to a flow regulating device 106. The vaporising cylinder 86 has fins 89 between which is coiled the gas warming line 96 and over which flows warm air from a source 101. In operation and assuming vessel 10 to have been charged with crude liquid oxygen through a port 22 in a housing 19 for a fill valve 34, a vent value 35, a pressure build-up valve 36 and a relief value 48 liquid is forced by gravity through an ambient airheated pressure build-up vaporizer 75 and the vapour traverses a pressure closing valve 62 within a housing 52, a line 56 leading to the housing 19 past the valve 36 and through a line 20 to the gas space of the vessel 10. At a predetermined pressure therein valve 62 is automatically closed by a pressure responsive bellows 61 and crude liquid is forced through lines 82, 91 to the vaporizor 86 and gas mixture so generated passes a check valve 116 to the flow regulator 106. An increase in reservoir pressure results in contraction of a bellows 66 and opening of a valve 68 thereby allowing passage of substantially pure oxygen from the gas space of vessel 10 through a line 108 leading to the regulator 106. In a modification the unvaporized impurities are collected in the base of the vaporizing cylinder and one aspirated into the warmest stream of substantially pure oxygen.

Title: Heat exchanger system
IPC: F28D7/12
Filed: 1977-09-23
Abstract: 1532757 Heat exchanger system SULZER BROS Ltd 23 Sept 1977 39752/77 Heading F4S In a heat exchanger system for a high temperature gas-cooled reactor, a primary gas at high temperature yields useful heat to a working gas. The primary gas enters and leaves the system as indicated at the bottom left of the Figure. The working gas enters and leaves as indicated at the top of the Figure. Heat exchange occurs between the gases (a) where they are respectively outside and inside of sheathing tubes 31 and (b) in countercurrent heat exchangers 47 comprising tubes 41. Flow of the primary gas is guided by a central cylindrical jacket 21. Primary gas passes through supply pipe 25, static mixer 27 and then up through the cylindrical jacket 21 where it contacts the outsides of the sheathing tubes 31 and is cooled. Thereafter the primary gas passes over the top of the jacket 21 and down through tubes 60 which surround the heat exchange tubes 41. The primary gases then pass downwardly to a rotor 73 whence they are blown upwardly through an annular chamber 78 and then pass downwardly through an outer annular chamber 79 and are returned via a duct 15 to the reactor core chamber. Working gas to be heated passes down through annular spaces 53 and 51, thence through tubes 50 and 42 and thereafter upwardly through the tubes 41 where it is heated by counterflow heat exchange with the primary gas flow. The working gas then passes into a dome 6, downwardly through the sheathing tubes 32, where further heating occurs, and upwardly through inner tube 33 and away from the system through an outlet pipe 37 to a heat load such as a gas turbine group or a chemical plant. A modified heat exchanger system which is similar but enables inspection or testing with little dismantling is illustrated in Figs. 2 and 3 (not shown).

Abstract: 974,864. Controlling aircraft. MINNEAPOLIS - HONEYWELL REGULATOR CO. Dec. 1, 1960 [Dec. 1, 1959], No. 41439/60. Heading B7G. [Also in Division G3] In Fig. 1A, D.C. signals produced by the pick-off of a gyro-vertical 19 in response to manual banking of an aircraft are applied to a servomotor system 55 which drives a signal generator 20 to nullify the signals from the gyro-vertical. When it is desired to maintain a manually set angle of bank automatically, the input to servomotor system 55 is short-circuited so that any difference between the signals from gyro vertical 19 and signal generator 20, due to change in the angle of bank, is effective to correct the. aileron position through servoamplifiers 14, 15 controlling hydraulic servomotors and actuators (not shown). A signal dependent on rate of roll is added to the two control systems from a gyro 18. Follow-up is provided from potentiometers 36, 41, operated by the hydraulic servomotors. A.C. signals from a compass 61 are maintained at a null by a servomotor system 66, but if it is desired to introduce automatic steering, the switches shown are moved to position E. The compass signals are then applied to servomotor system 55 to maintain the course by adjustment of signal generator 20. To prevent shock on changeover to this form of control, a signal originating from gyro-vertical 19 is faded out slowly by a condenser 69 after changeover. Manual control of the ailerons is effected by a control column, Fig. 1B (not shown), operating on differential linkages between the hydraulic servomotors and actuators.
