Abstract: 798,704. Generating combustion products under pressure. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. Dec. 6, 1955 [Dec. 23, 1954], No. 35002/55. Class 51 (1). [Also in Groups XXVI and XXIX] A device associated with a gas turbine propulsion engine for starting-up the engine comprises a reversible-flow, bladed wheel which can operate either as a turbine for starting-up the engine when supplied with fluid under pressure from an external source, or as a compressor for supplying air at high pressure which is utilized to improve combustion in the combustion chamber of the gas turbine engine. The device is shown in Fig. 1 adapted to operate as a starter turbine and comprises a radial-flow wheel 1 adapted to rotate a gas turbine engine, not shown, through gearing 4 and a clutch 5. The turbine wheel 1 is supplied with combustion gases from an auxiliary combustion chamber 10 which receives air from a reservoir. The gases flow through the duct 9 and inlet nozzle guide vanes 6a on to the rotor blades and finally exhaust through the duct 8. The gas supplied to the turbine could alternatively be unheated air under pressure. Valves 15 and 12 are open and valves 13 and 15a are closed during operation as a turbine. The device is shown in Fig. 2 when operating as a high-pressure compressor. Air tapped from the outlet 14 of the compressor 14a of the gas turbine engine passes through duct 11 to the centre of the wheel 1 which is now operating as a centrifugal compressor. The air is thus further compressed and passes through duct 9a to a small auxiliary combustion chamber 16 which is disposed within the main combustion equipment 16a of the gas turbine engine and which is adapted to ensure reignition in the main combustion equipment during conditions of low ambient pressure. Valves 13 and 15a are open and valves 12 and 15 are closed during this operation. The air supply to the compressor 1 may be from a source other than from the outlet of the main compressor 14a. A control device comprising a governor which is dependent on engine speed and a barometric capsule responsive to the pressure difference between atmospheric pressure at ground level and at the operating altitude is provided to operate the various valves, the vanes 6a if they are of the adjustable type and the clutch 5.

Title: Improvements in or relating to packing or wrapping machines
IPC: B65B7/04
Filed: 1934-12-13
Abstract: 442,464. Closing filled cartons. RIGGLESWORTH, G. H. J., and MOLINS MACHINE CO., Ltd., 2, Evelyn Street, Deptford, London. Dec. 13, 1934, No. 35802. [Class 94 (i)] The open ends of cartons containing tea &c. are closed in such a manner as to form a sharply defined crease at the point where the flaps are folded. A folding element to close the flap operates in conjunction with means to engage the flap and to move it towards its hinge axis to form a crease. The cartons 1 are carried in pockets of a conveyer to the closing station with the flaps 5-8 upstanding. A folder 9 pivoted at 11 to a lever 12 moves down into the position shown in Fig. 2 to close the flap 6. The lever 12 is moved by a cam 15 until stopped in its advanced position by an abutment 25 with the pivot 11 above and behind the hinge axis of the flap. An associated lever 19, connected to the lever 12 by a lost motion device 23, 24, continues moving until a roller 18 has pressed down the folder 9 against the action of a spring. The folder 9 is formed with an abutment 20 which describes an arc 22, Fig. 4, intersecting the arc 21 which the edge of the flap 6 would describe if freely rotated about its axis 17. At the point of intersection of the arcs, the abutment engages the edge of the flap and moves the flap slightly towards its axis, thereby forming a sharp edge at 17. The folder 9 and associated parts withdraw and the opposite flap 8 is turned down by a folder 10 mounted on a pivoted bracket 128. The bracket is turned slightly on its pivot 130 by the action of a roller 28 on the surface 129, the .roller continues its movement to. turn down the folder 10 to fold and engage the flap 8 in a manner similar to that of the flap 6. During the folding of these flaps, the flaps 5, 7 are held outwards by members 32, 33, Figs. 2 and 5, which are lowered into position on an arm and rocked about pivots 34 in the direction .of the arrows, by the engagement of tails 39 with fixed stops 40. The members are also pivoted at 41, so that as the carton is moved away, they may swing in the direction of the movement of the conveyer. The flaps 5, 7 may be folded down by mechanism similar to that which turns down the flaps 6, 8, or by any suitable mechanism. Specification 16870 /07, [Class 94], is referred to.

Abstract: 895,732. Sawing. HACK, F. W. Oct. 19, 1960 [Oct. 28, 1959], No. 35861/60. Class 145. A band saw machine for cutting chrome, tool and cold-rolled steels, cast-iron, wood, plastic, paper and other soft metals comprises a band saw 58 carried by a frame 38 which is mounted on a pivot pin 35 on a base 11 and is movable from a generally vertical position to an inclined position to move the operative portion of the saw in its own plane, and a releasable brake 67 co-operable with the pivot pin for maintaining the frame in the vertical position and in selected inclined positions so that when pressure is applied to the frame, the saw is fed into the stock to be cut. The frame carries two or more discs 57, 60 on which the saw is guided, and a bracket 48 supporting a motor 45 and a beltdrive leading to a worm-and-wheel mechanism 43, 44 connected by a shaft 40 to the disc 57. The frame has a block 34 in which is keyed one end of the pivot pin 35, the other end of which is rotatably mounted in a block 32 on the base. The block 32 is formed with a flange 70 having a friction lining 72 co-operable with a cap 71 which can be pressed into contact with the lining by a nut 74 on a threaded extension 69 of the pin 35 to form the brake 67. When the frame is in its vertical position, the saw can be engaged with a workpiece mounted on a worktable 12 held in position by a clamping screw 22. The worktable can be swung about a pivot 15 to an inoperative position when the screw 22 is released. Release of the brake 67 permits the frame 38 to be swung to an inclined position where it can be retained by re-engaging the brake. A weight 76 can be moved along a rod 75 to cause the frame to move against the restraint of the brake so that the saw is fed into a workpiece supported on a second worktable 13. Both worktables can be adjusted to inclined positions. In a modification, the frame is inclined at an angle of 20 degrees to the axis of the pivot pin, the operative portion of the saw being maintained perpendicular to the axis so that long workpieces may be cross-cut.

Title: A method for recovery of selenium from a selenium or its compounds-enriched solution
IPC: C01B19/00
Filed: 1960-10-19
Abstract: Selenium dioxide is produced from water containing free or combined selenium by introducing the water in atomized form into a gas comprising free oxygen, e.g. air or oxygen, in the presence of a metal oxide oxidation catalyst, preferably cupric oxide, ferric oxide, or nickel oxide, at a temperature of 500 DEG -700 DEG C. The oxide may be deposited on a carrier, e.g. silica or diatomaceous earth.  The water containing the free or combined selenium may be obtained by contacting the reaction gas from a process for the production of, for example, acrolein or acrylonitrile from propylene, in the presence of selenium, with water at pH 7-9 and a temperature not exceeding 50 DEG C., and the selenium dioxide produced may also be used in such a process.ALSO:Acrylonitrile is prepared by contacting a propylene-air mixture at 310 DEG C. with metallic selenium which vaporizes, and a mixture of the resulting selenium-containing gas and ammonia is fed firstly over copper oxide at 400 DEG C. and secondly over molybdenum oxide. The product gas containing acrylonitrile is scrubbed with water which dissolves all selenium and compounds thereof present, and the solution so obtained is atomized into a gas comprising free oxygen in the presence of a metal oxide oxidation catalyst at a temperature of 500-700 DEG C. All selenium and compounds thereof present are converted to selenium dioxide which is used subsequently instead of selenium in the process for producing acrylonitrile.
