Title: Catalytic selective hydrogenation of light,diene-containing cracked hydrocarbon oils
IPC: C10G45/32
Filed: 1961-10-19
Abstract: Light cracked diene-containing hydrocarbon oils, having a final boiling-point of not more than 375 DEG  C., are subjected to selective catalytic hydrogenation at temperatures below 280 DEG  C. in the presence of hydrogen-containing gas, characterized in that the total amount of hydrogen sulphide present in the streams supplied to the reaction zone is not more than 0.1 kg. per 1000 kg. of hydrocarbons present in these streams.  The hydrogen-containing gas may be a surplus gas, from a catalytic reforming plant, which has been at least substantially freed of hydrogen sulphide.  The hydrogenation is preferably effected at a pressure not exceeding 100 kg./cm.2 abs.  The ratio of the amount of hydrogen containing gas to the total amount of hydrocarbon oil is preferably in the range 50-300 N.1/kg. The oil is present preferably at least partly in the liquid state. The oil may be a gasoline obtained as a by-product in the drastic cracking of hydrocarbon oils for the production of normally gaseous alkanes, for example in the presence of steam.  A diluent oil, or recycle oil, may be added.  The preferred catalyst is nickel supported on a carrier such as Al2O3 or a material containing Al2O3, BaSO4 or BaCO3, and may be sulphurized before use.

Title: Captive toy aeroplane
IPC: A63H27/04
Filed: 1954-12-30
Abstract: 759,748. Toy aircraft. ERNST, M. Dec. 30, 1954 [Dec. 31, 1953], No. 37615/54. Addition to 749,661. Class 4. A captive toy aeroplane having an airscrew actuated by a transmission shaft which is operatively connected with driving means remote from the aeroplane by means of a flexible shaft connected to the transmission shaft at one side of the aeroplane, at or near the outer end of a wing thereof, as claimed in the parent Specification, is characterized by the fact that the flexible shaft consists of a wire coil 20 arranged so that the direction in which the coil is wound and in which the torsional driving-force is applied to the driving-shaft, tends to close up the coils and decrease their diameter. The centre of gravity of the aeroplane is located ahead of the centre of lift in normal flight and the direction of rotation of the shaft 20 is selected so that the torque exerted thereby on the aeroplane tends to increase its angle of attack. The shaft 22 is at an obtuse angle to the propeller shaft 21 and the tail wheel 26 is so inclined that when in contact with the ground it will tend to turn the aeroplane away from the operator and maintain the shaft 20 fully extended.

Abstract: 997,285. Control of D.C. motors; rectifying. BRUSH ELECTRICAL ENGINEERING CO. Ltd. Oct. 17, 1962 [Oct. 20, 1961], No. 37647/61. Drawings to Specification. Headings H2F and H2J. The armature or field winding of a D.C. motor is connected to two bridge converters in reverse-parallel, one bridge acting as a rectifier and the other as an inverter and their functions being mutually interchangeable for reversing the direction of rotation. The gate firing pulse signals for the two converters are controlled independently of each other so that the back E.M.F. of the converter, which acts as inverter during normal operation of the motor, is always greater than the output E.M.F. of the converter which acts as a rectifier, thereby to limit the current circulating between the two converters. A standing bias is used for controlling the gate firing pulse signals so that the two converters are in the inverter region when there is no control signal.

Title: Improvements in and relating to shaft driving mechanisms
Inventor: HACKETT LOUIS ALFRED
IPC: B04B9/08
Filed: 1960-11-04
Abstract: 924,791. Disc brakes. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 30, 1961 [Nov. 4, 1960], No. 37992/60. Class 103 (1). [Also in Group XXIV] A driving mechanism between a first (driving or driven) member and a shaft comprises a second member fast with the shaft and having a lost-motion connection with the first member, and a third member drivingly connected to the first member and shifted axially upon relative rotation between the first and second members which occurs upon torque reversal between the first member and the shaft. Axial movement of the third member may be used to brake the shaft, or to indicate torque reversal or to increase the power input to the driving member. As applied to a centrifugal hydro-extractor having a basket fast with the shaft which is to be braked upon removal of driving power from the driving member, the first member is the rotor 1 of an electric motor which is freely rotatable on the shaft (not shown) to be driven. Axial pins 5 engage with lost-motion in recesses 6 of the second member 7 which is pinned or keyed to the shaft. Axial pins 8 slidably engage apertures 9 formed in the third member 10, which is freely mounted on the shaft and which lightly frictionally engages a spring-biased non-rotary table 12. The member 7 has projections 14 extending into slots 13 formed between raised inner peripheral portions of the member 10, rollers or balls 15 being housed in the slots 13 and co-operating with inclined portions of the slots. When the rotor 1 drives the shaft the rollers 15 are fully housed in the slots and there is only light engagement between the member 10 and table 12. If the speed of the driving member is reduced and due to its inertia the driven shaft continues to rotate at a higher speed, relative movement between the members 1 and 7 causes the rollers 15 to ride up the inclines and move the member 10 axially to increase the frictional engagement with the table 12 thus providing a braking torque.

Abstract: 1477049 Paper-making apparatus BELOIT CORP 6 Sept 1974 [14 Sept 1973] 39045/74 Heading D2A In a twin-wire machine including an arcuate forming zone 14, the outer wire 10 is separated from the inner wire 12 at a first point 34 upstream of a second point 35 where the inner wire 12 is separated from the zone 14, and the inner surface of the inner wire is blocked by the imperforate surface of a shoe or roll at the points 34, 35 to ensure that the formed web W follows the inner wire. As shown the imperforate surface and the arcuate forming zone 14 are defined by a solid cylindrical roll 15, and an adjustable guide roll 16 allows the angle of divergence between the wires 10, 12 to be varied, e.g. up to 5. The divergence of the wires is said to create a low pressure zone between them which is filled by air flow through the outer wire 10 since flow through inner wire 12 is blocked. This flow cleans the wire 10 and forces the web onto the inner wire 12, being assisted by the surface tension of water in the inner wire mesh. Dewatering of the web is achieved through outer wire 10 into savealls 33, 33a and later through inner wire 12 into saveall 15a. The angle of stock flow into the zone 14 can be adjusted, as shown, by providing a pivotally-mounted headbox 26.
