Patent GB-2075859-A (GB)
Title: Catalytic reactor with internal heat exchanger
IPC: B01J8/00
Filed: 1981-04-02
Abstract: A reactor and associated method for performing exothermic or endothermic gas-phase catalytic reactions uses at least one, usually fixed, bed of catalyst whilst transferring heat to or from another medium by means of a process gas stream flowing from or to the or each bed by way of a tubular heat exchanger within and extending axially through the catalyst bed(s). Preferably the stream is directed via annular passages to a central tubular heat exchanger. The gas side of the exchanger is usually divided into sections by intermediate tube-sheets. The reactor is particularly suitable for methanol synthesis from hydrogen and oxides of carbon; the heat being recovered as steam produced in the central tubular heat exchanger.

Title: Vehicle suspensions for tandem axles
IPC: B60G5/04
Filed: 1981-09-14
Abstract: Tandem axles 1 and 2 in a vehicle suspension carry downwardly projecting brackets 5 and 6 pivotally connected to opposite ends of longitudinal beams 3 formed with seatings for pairs of inclined spring bolster elements 13 of rubber and steel plate sandwich construction permitting pivotal movement of the beams 3 about a transverse axis.

Title: Improvements in hydraulic control apparatus for controlling the operation of mine roof support props
IPC: E21D23/26
Filed: 1980-04-08
Abstract: Hydraulic control apparatus serves to operate roof support props of a mineral mining installation and employs a manually-operable main valve device 11 which can be set to various positions to selectively connect fluid pressure and return lines P, R to the working chambers 10@1<1>,  10@1<2> of at least one associated prop 10 to thereby cause extension and retraction of the prop. A pressure- relief valve device 12 is connected to the particular prop chamber 10@1<1> charged with pressure fluid by the main valve device 11 to effect extension of the prop. The relief valve device 12 is automatically set by pressure control means 11, 42, 41, 40, 39 to respond to a significantly higher pressure whilst the prop 10 is actually being extended (state 1) and set by the main device 11 and reverts back to its normal response pressure once the prop 10 is set (state 0). <IMAGE>

Title: Improvements relating to heat exchangers
Inventor: LARDNER GRAHAM GERALD
IPC: F28D1/053
Filed: 1982-07-20
Abstract: A heat exchanger such as a vehicle radiator comprises a pair of tube plates 11, 12 between which flat tubes 13 extend, interspersed with corrugated fins forming airways 14. Header tanks are formed by attaching shells (not shown) to the tube plates. In production of the radiator, the tubes and corrugated fins are assembled, between clamping channels 15, as a separate item. To hold the matrix together, ties 16 hold the clamping channels together. The ties have end portions 17 which are bent laterally with respect to the axes of the ties, and which extend in different, preferably substantially opposite directions. Thus the ties can only be removed from the apertures in the channels by twisting the ties about their axes, and thus cannot jump out as a result of vibration. <IMAGE>

Title: Programmable controller
Inventor: CARTER BRIAN
IPC: G05B19/12
Filed: 1983-06-03
Abstract: A programmable controller, for central heating systems for example, has an optical input (LED 3) and an optical output (Sensor 11) on a common axis 2, which are connected via an off-axis observation point where the optical path intersects a programme member 5. The latter can be made selectively opaque and transparent as required, and is rotatable about the axis 2 relative to the observation point; as described the optic fibre 9 feeding sensor 11, together with a fibre 10 giving a visible display of the state of the controller, is rotated, either by a clock for a timer, or by an ammeter for a delesteur (selectively disconnects low priority devices if total load exceeds a threshold). Also described is a thermostat where a mirror on a laminated strip does or does not reflect light from an input optical fibre to an output fibre. Timer, delesteur and thermostat may be connected optically in series, have a single input light source and single output sensor. <IMAGE>

Title: A damped rotary-oscillation or torsional vibration eradicator
Inventor: FEDERN KLAUS
IPC: F16F15/167
Filed: 1983-06-06
Abstract: The damped rotary-oscillation eradicator has annular secondary rotary masses 1, 2 which engage the one around the other and which are connected to the primary mass by sleeve-shaped parallel-acting visco- elastic spring elements 5, 6 which engage around one another in a cascade-like manner from two sides. At the two-sided free surfaces of the spring elements, 5, 6 these are freely accessible, during production, for shaping tool or mould parts, so that the edge cross-sections of the spring elements 5, 6 are relieved of (or do not provide) connection surfaces between the spring elements 5, 6 and the metal parts 1, 2.

Title: Elevating mechanism
Inventor: EDWARDS STANLEY ALFRED
IPC: A47B9/02
Filed: 1983-11-08
Abstract: An elevating mechanism comprises a carriage (9) slidable on a vertical guide member (6). A releasable locking pin (42) on the carriage is engageable in a hole in the guide member to lock the carriage to the guide member. A platform (59) is connected across the carriages of two adjacent mechanisms. A counterweight (49) is connected to the carriages via a rope (45) and pulleys (48). The counterweight bias assists upward movement of the carriages. The rope (45) is reeved around pulleys connected to locking pins (42) so the counterweight holds the locking pins engaged. A "T" handle (28) is rotatable to withdraw the pins (42) and then apply a vertical load to raise or lower the platform and carriages. Inadvertent release of the pins (42) by the handle (28) is prevented by a spring loaded locking pin (53). The platform may carry a leisure activity layout such as a model train track. <IMAGE>

Title: Fluid flow control valve
Inventor: HUGHES HAROLD
IPC: F16K3/28
Filed: 1983-11-17
Abstract: In a fluid flow control valve a closure member 18 of deformable material is secured to or forms part of a carrier 17 rotatably connected to a valve stem 7 mounted for rotation and longitudinal movement within the valve body so that, upon rotation of the stem 7, the carrier 17 is caused to rotate with the stem 7 and move longitudinally until the closure member 18 engages a wall 6 of the bore whereupon continued movement of the valve stem causes the closure member 18 to move longitudinally without rotation to seal deformably into contact with the end wall 6. The closure member 18 may be complementary with the bore 3, and may be of plastics, rubber or other elastomers. Various ways of connecting the carrier 17 with the stem 7 are described. <IMAGE>
