Title: Gas supply conduit system
Inventor: BROOKES GEORGE
IPC: G01F15/18
Filed: 1984-04-18
Abstract: A bracket 42 for supporting a gas meter 2 has a platform 46 and a backing plate 44 which is secured to a wall. The platform has oppositely faced notches 50 and 52 each receiving a respective coupling 14 or 28 annularly grooved for engagement by the sides of the notch so that the engaged couplings cannot pass downwards through the notches. Coupling 10 is connected to meter inlet 6 and coupling 28 to meter outlet 10 whereby the meter is suspended from the platform. Gas from the mains is supplied by a pipe to a pressure reducer 4 connected to the upper end of coupling 14, and gas is supplied to a gas consuming appliance by another pipe connected to the upper end of coupling 28. The couplings connected to the meter are at the closed ends of the notches so the meter cannot be dislodged from the platform. <IMAGE>

Title: Disposal of toxic waste
Inventor: BURTON WILLIAM ROBERT
IPC: G21F9/24
Filed: 1984-12-13
Abstract: Toxic waste, e.g. radioactive liquor, is disposed through borehole 20 into a stagnant sub-zone 23, preferably below the sea bed 14, at a flow rate sufficiently low for the disposal flow to be wholly or substantially by natural pressure head difference between the liquor (of higher density than the natural water in the sub-zone) and the natural water in the sub-zone.

Title: Fibre-reinforced ceramic materials
Inventor: BAKER ANDREW ROBERT
IPC: B28B1/26
Filed: 1985-04-02
Abstract: A method for manufacturing a fibre reinforced ceramic material which comprises forming a preform (11) of ceramic fibres, placing the preform in a porous mould (12, 13) and applying a ceramic slip (14) to the preform in the mould. The slip material (14) is then caused to impregnate the preform (11) by applying a pressure differential thus forming an impregnated preform (15).

Title: Capacitor diode level shift circuit
Inventor: EDEN RICHARD C
IPC: H03K19/0185
Filed: 1985-10-22
Abstract: A voltage level shifter 22 includes a revise-biassed Schottky diode capacitance 10 biassed by three small Schottky diodes 12, 14, 16. The bias current is provided by a FET 18 connected to a negative supply VEE. Manufacturability is attained by making the circuits tolerant to variations in MESFET pinchoff voltage and by reducing current differencing. High performance at low power is achieved by minimizing the current wasted in level shifting and by carefully controlling the internal logic voltage swings to maintain MESFET operation in high ET regions. Typical gate operating frequencies are in the dc to 3GHz range with a Lg = 1 micro meter, Vp = -1.0V GaAs D-MESFET process. <IMAGE>

Title: Drive reversal mechanism
Inventor: GRIFFITHS EDWARD PETER
IPC: F16H3/60
Filed: 1985-12-24
Abstract: A reversible drive mechanism typically for use in a crop harvester comprises a rotatable input drive 21 and a rotatable output drive 1. The output drive 1 is normally driven by said input drive 21 via a disengageable drive connection 22, 23, 24, and the input drive 21 and said rotatable output drive means 1 are also connected by a constant mesh epicyclic gear arrangement 3, 5, 11, of which the sun gear 3 is fixed to input drive 21, the ring gear 5 is fixed to the output drive 1. Disengagement of the disengageable drive connection 22, 23, 24 between the input drive 21 and the output drive 1 and the activation of braking means 19, 20 to prevent rotation of the rotatable carrier 15 cause drive to be transmitted to the output drive via the epicyclic gear mechanism 3, 5, 11 such that the direction of rotation of the output drive 1 when driven via the epicyclic gear arrangement 3, 5, 11 is opposite to the direction of rotation when it is normally driven. In an alternative embodiment the brake is constituted by a fixed belt which engages a V- pulley on the carrier, this moving the two parts of the pulley apart to disengage a clutch. <IMAGE>

Title: Hazardous waste reactor system
Inventor: GALLOWAY TERRY R
IPC: F23G5/00
Filed: 1986-07-30
Abstract: A thermal decomposition reactor accepts solid, liquid or gaseous waste products of industrial processes or the like and rapidly reduces same to carbon dioxide and water and a safe glassified non- leachable ash without limitation by types of hazardous waste materials that may be included in such waste. Solid and liquid wastes are fed into an opening 73 at the top of a hollow cylindrical core 71 which is electrically heatable to temperatures approaching 3000 DEG F. Gaseous waste is mixed with a carrier gas and passed from an inlet 87 into an outer shell 52 and thence to the reaction zone defined by the core 71. As shown, a labyrinth formed by the shell 52 and coaxial tubes 54,61 directs the gas flow. The core 71 is divided by two parallel, helical slots to form two separate parts of an electric circuit. Packed beds 106, 107 increase the transfer of heat from the core 71. In the embodiment of Fig. 1 the carrier gas is directed upwardly through the core. Its rate of flow determines the residence time of the waste in the reaction zone. <IMAGE>

Patent GB-2181594-A (GB)
Title: Electrochemical devices
Inventor: ELSON DEREK ALEXANDER
IPC: H01M50/469
Filed: 1986-09-22
Abstract: An electrochemical device comprises a separator 20 in the form of a generally tubular wall having an inwardly folded portion which at least partially closes one end thereof, and a fluid material 27 which is bonded to the inwardly folded portion so as to close and seal the one end. A method for forming such separator includes a step of reducing the mechanical rigidity of the one end before it is inwardly folded. The separator 20 may be formed by winding a separator material on a mandrel. The one end of the tubular wall may be folded by a spinning action between the wall and a crimping means acting on the wall. The method may include clamping the tubular wall against the mandrel but it may be such as to allow the separator 20 to rotate if the frictional drag on the separator due to spinning becomes excessive. The pressure within the tubular wall may be reduced so as to assist inwardly folding. An electrochemical device comprising the separator 20 may be formed by placing an outer cell portion 30 and other electrochemical parts 32 pre-placed in the outer cell portion over the separator before or after the settable fluid material 27 has cured. <IMAGE>
