Patent GB-2039293-A (GB)
Title: Conversion of fuel to reducing and/or synthesis gas
IPC: C10J3/54
Filed: 1979-01-09
Abstract: The invention relates to the conversion of fuel (solid and/or liquid) to reducing and/or synthesis gas by contacting the fuel in a fluidized conversion bed (13) with a solid oxygen donor (e.g. CaSO4) at a fuel conversion temperature (e.g. 850 to 1150 DEG C) in the presence of at least one gas/vapour phase substance such as H2 and/or H2O and/or CO and/or CO2 which serves to promote and or mediate the transfer of oxygen from the donor to the fuel and preferably in the absence of non-reactive gases (e.g. N2) whereby the fuel is converted to a reducing and-or synthesis gas product by (inter alia) partial oxidation employing the oxygen of the solid oxygen donor, the latter being reduced (e.g. CaS). The reduced donor is exothermically oxidized in a fluidized oxidation bed (35) by contact with an oxygen-containing gas (e.g. air) and re-used for converting further quantities of fuel. Moieties (e.g. sulfur/sulfur compounds) whose presence is undesirable in the gas product may be removed by a solid moiety-fixing agent (e.g. CaO) in the conversion bed (13). The moiety-fixing properties of the latter are at least partly regenerated in a fluidized regenerator bed (48) by treatment in a suitable regenerating atmosphere, and the regenerated moiety-fixing agent is returned to the conversion bed (13) directly and/or indirectly via the oxidation bed (35).

Title: Control valve assembly for downhole tool
IPC: E21B33/127
Filed: 1980-01-23
Abstract: A control valve assembly for a downhole tool, for example an inflatable packer, in a well, comprises a valve body 24 having an inlet 26 communicating with the interior of a mandrel 18 and an outlet 30 for directing fluid to inflate the packer. Two lengthwise bores in the valve body house respective pistons and extend between an end 54 (communicating with the well annulus) of the valve body and (respectively) the inlet 26 and outlet 30. Piston 76 is held by shear pin 82 until a pressure differential there-across reaches a first level at which it is released and is moved to a position allowing fluid communication between inlet and outlet via the second bore. The second piston (not shown) is held until a pressure differential there-across reaches a higher level, at which it is released and is moved to a position blocking fluid communication to the outlet. <IMAGE>
Patent GB-2039803-A (GB)
Title: Method of Making a Metallic in Structure by Combined Flow Forming and Bonding
IPC: B21K25/00
Filed: 1979-01-26
Abstract: Metallic structures, especially those having intricate shapes, are fabricated using a combination of flow forming and bonding operations in a single step. A metal preform (30) having flow forming characteristics is positioned relative to a shaping member (20, 22, 24) and a metal workpiece (54, 56) to be joined to the preform. The preform is heated to a temperature range suitable for flow forming. Pressure is applied to cause the preform to flow form against the shaping member and the workpiece. The preform and workpiece are maintained under coordinated temperature-pressure-time duration conditions to produce metallurgical bonding of the preform to the workpiece. The bonding may be direct, so by diffusion bonding, or indirect, as by brazing using a brazing material which is interposed between the preform and workpiece. <IMAGE>

Title: Connecting reinforcement rods
IPC: E04C5/16
Filed: 1979-01-31
Abstract: Concrete reinforcing bars 12, 14 are joined end to end by inserting them into the open ends of a splicing sleeve which is then filled under pressure with a synthetic resin. The inner surface of the sleeve includes a plurality of grooves 18 which define conical surfaces arranged in a continuous series and which cooperate with the cured resin and irregular external surfaces of the bars to effect a very strong joint. The sleeve includes a number of longitudinally spaced injection apertures 28, which may be selectively plugged. Means also are provided to facilitate initial placement and orientation of the sleeve with respect to the bars to be joined. In a modification, one end of the sleeve is internally threaded to receive a threaded rod. <IMAGE>

Title: Liquid Storage Tank with Measuring Device and Method for its Operation
IPC: G01F23/00
Filed: 1979-02-19
Abstract: A liquid storage tank 38 is combined with a measuring device 10, 26, 28 arranged to measure either the quantity of liquid in the tank above a predetermined datum level or the change in the quantity of liquid in the combined system between two liquid levels. The measuring device comprises a body 28 suspended by a force transmission means 29 within a container 10 communicating with the storage tank 38. A gyroscopic load cell 26 measures the vertical force exerted on the body 28 and is calibrated to express the resultant vertical force as the appropriate quantity of liquid. A servo-operable inlet or outlet valve 37 to the storage tank 38 can be controlled by signals from the load cell 26 so that predetermined quantities of the liquid can be metered into or out of the storage tank 38. The apparatus may be used to calibrate dipsticks. <IMAGE>

Title: Manufacture of optic fibre cable
IPC: B29C48/05
Filed: 1979-03-14
Abstract: In a method of manufacturing an optical cable element comprising a plastics tube in which an optical fibre and/or optical bundle is loosely housed, the tube is extruded about the optical fibre as it travels under a controlled tension in such a way that the internal diameter of the tube is greater than the diameter of the fibre. On emerging from the extruder the tube is drawn successively through preliminary cooling means which sets the tube material, heating means which causes the tube to shrink, and final cooling means which resets the material of the tube after lengthwise shrinkage has occurred. Shrinkage of the tube whilst the cable is in store is limited to an acceptable value.

Patent GB-2026236-A (GB)
Title: Power transistor
IPC: H01L29/73
Filed: 1979-06-26
Abstract: A power transistor having improved turn-off characteristics and enhanced reversed second breakdown capabilities is described wherein the emitter of the transistor includes first and second regions, the first region 46 being laterally surrounded by the second region 42, 44 and having lower gain than the second region. Turn off is enhanced as essentially no current flows under the lower gain first region during turn off thereby facilitating the removal of excess charge carriers when the device is in the turn-off stage. The lower gain for the first region is obtained typically by reducing its thickness which in one embodiment is zero. The lower gain may also be obtained by isolating the emitter electrode from the central portion of an emitter region of uniform thickness. Preferably, the emitter region is comb-shaped. <IMAGE>

Patent GB-2060549-A (GB)
Title: Load carrying apparatus
IPC: A01D90/08
Filed: 1979-10-09
Abstract: A wheeled chassis has two sections 10 and 11, section 10 having a towing eye 12 and section 11 having a bale-carrying arrangement. The two sections are relatively slidable along the length of the chassis, by means of a hydraulic ram acting therebetween. The bale-carrying arrangement includes a sub-frame 13 pivoted to section 11 and supporting road wheels 17, ram 18 also acting on the sub-frame. By selectively locking the sub-frame 13 to section 11 or section 10 to section 11, operation of ram 18 causes either elongation or contraction of the chassis, or pivotal movement of the sub-frame, lifting the road wheels clear of the ground when the sub-frame is pivoted to extend generally vertically (Figure 2). Straw bales may be carried on the sub-frame 18 and held in place by means of a pair of side gates 32 (Figure 2), movable laterally with respect to each other to clamp or release bales therebetween. <IMAGE>

Title: Boundary Layer Control
IPC: B64D15/04
Filed: 1981-02-12
Abstract: To allow an aerofoil such as a wing to operate at a large angle of attack, especially at low Reynolds Number when the boundary layer is laminar, some of the free stream air is ducted into the inside of the wing by an intake slot 2 at the wing leading edge and ejected from exit slots or holes 3 along the wing upper aft surface so that the boundary layer on the wing upper outer surface always flows aft and does not separate. The invention does not require any additional power sources or mechanical devices in order to operate and it need not reduce the fuel carrying capacity of the wing. It can operate in wet, icy or dusty conditions. Engine bleed air may be used to prevent intake and exit hole icing. The exit holes may be closable by a sliding plate. <IMAGE>

In a modification the water level indicating device is in the form of a weighted member marked with a scale readable against a fixed marker. <IMAGE>
