Title: Method of effecting fluid flow in porous materials
Inventor: FINNEBRAATEN JORN INGE
IPC: E02D1/02
Filed: 1995-10-05
Abstract: A method of effecting fluid movement in metal reinforced concrete 1 is disclosed in which a sequence of voltage pulses are applied between spaced apart first and second electrodes 4, 5 having a region of the porous concrete 1 therebetween. Each voltage pulse comprises a first portion in which an electroosmotically active first potential difference is applied between the first and second electrodes 4, 5 to effect fluid movement in the region of porous concrete 1, and a second portion in which a second potential difference of opposite polarity to the first potential difference is applied between the first and second electrodes 4, 5. A voltage is applied to a metal reinforcement 2 located at least partly in the region of porous concrete 1 to make the voltage of the metal reinforcement 2 negative with respect to the porous material 1 adjacent thereto for at least part of the sequence of voltage pulses.

Title: A cryogenic cooling apparatus
Inventor: KANEKO TOMOMI
IPC: F17C13/00
Filed: 1995-10-25
Abstract: A cryogenic cooling apparatus has a thermal switch wherein cooling can be efficiently performed in a temperature range from room temperature to very low temperatures, without using a refrigerant for cooling an object such as a superconducting coil. The cryogenic cooling apparatus includes a vacuum container for containing the object, and at least one refrigerator (4) for cooling the object, the refrigerator (4) being provided with a high-temperature cooling stage (7) and a low-temperature cooling stage (5) arranged at a predetermined distance from each other. The thermal switch comprises at least one high-temperature-side heat transfer member (23) attached to the high-temperature cooling stage (7), at least one low-temperature-side heat transfer member (23) attached to the low temperature cooling stage (5) and a sealed container (24, 25) containing the heat transfer members (23), and which is filled with a gas e.g. nitrogen for heat conduction between the heat transfer members. When cooling down of the superconducting coil is started by the refrigerator, heat is conducted from the cooling stage (5) to the cooling stage (7), so cooling a thermal shield around the coil. The operation of the thermal switch continues when the gas is in the liquid state, but ceases when the gas solidifies. <IMAGE>

Title: Digital video effects apparatus
Inventor: BANKS NICK
IPC: G06F3/0484
Filed: 1996-04-12
Abstract: A digital video effects apparatus has a graphical user interface having a display 10 upon which is produced a background image 21 and a foreground video image 13,14 within a predetermined shape, the foreground image being rotated in time and space to represent a 3-dimensional effect. Control points 22, 23, 24 are set by a user together with rotation angles and x-y scaling parameters of the video image. The apparatus interpolates between the control points to provide a smooth transition 15 from control point to control point. The display preferably windows an area (25, Figure 4) which is filled by the foreground image, so that only a part of the background image may be included. The windowed display is zoomed in and out as the foreground image changes orientation and/or size so that it substantially fills the windowed area. The display enables the operator to view the whole of the foreground image being rotated even when it is outside the intended (visible) image area 21.

Title: Hand truck for lifting and transporting a reel with a central core
Inventor: CAMPBELL JOHN
IPC: B65H49/38
Filed: 1996-08-09
Abstract: The reel-transporter hand truck has an upright frame 2 at the base of which are provided a pair of ground engaging wheels 4. A generally cylindrical mandrel 7, arranged to be received by the core of a reel to be lifted, projects from the front of the frame 2. The mandrel comprises a deflecting member 10 which is arranged to be deflected outwardly relative to the mandrel axis 11 as the transporter frame 2 is tilted backwards to cause the mandrel to take the weight of a paper reel. The deflecting member 10 is thus forced against the inside of the reel core, causing the mandrel to self-lock within the core.

Title: Manufacturing elements faced with superhard material
Inventor: MATTHIAS TERRY RICHARD
IPC: E21B10/573
Filed: 1997-07-26
Abstract: A method of manufacturing preform elements comprises the initial step of forming a preliminary component including a facing table of superhard material having a front face, a peripheral surface, and a rear surface bonded to a less hard substrate 10. The rear surface of the facing table and the front surface of the substrate are formed with inter-engaging projections and recesses 11, 12 to provide a non-planar interface between the substrate and facing table. There are then cut from the preliminary component a plurality of separate preform elements 14 each having a facing table and substrate with a non-planar interface between them. The configuration of the non-planar interface of the preliminary component may vary with distance from its centre, so that the non-planar interface of each preform element also varies in configuration across the width of the element.

Title: System for injecting nitrogen oxide reducer into an exhaust gas flow
Inventor: ENDERLE CHRISTIAN
IPC: F01N3/08
Filed: 1997-11-07
Abstract: A system for injecting a nitrogen oxide reducer into an exhaust gas flow, in particular for a combustion engine, has a injection element for controlled injection of the reducer into the exhaust gas flow. The injection element contains a micromechanical nozzle element 1a, 1b which injects the reducer controllably into the exhaust gas flow through a multiplicity of fine nozzle openings 10 in the form of fine jets by means of local, measured generation of overpressure.

Title: A seismic surface wave process for the remote clearance of anti-personnel land mines
Inventor: MELVIN ALEC
IPC: F41H11/12
Filed: 1998-03-12
Abstract: A surface seismic wave process employs ground displacement resulting from the propagation of Rayleigh surface waves, as in Figure 1, from a seismic source located in a borehole at the ground surface to initiate the operation of anti-personnel mine fuses and consequently to detonate the mines in which they are installed for ranges of up to and in excess of 100 metres from the source and hence provide protection from the hazards of accidental close range mine detonation for demining operatives. The maximum range at which the process is effective for demining is determined by the sub-surface geology of the area in which the mines are laid. A range of seismic sources of appropriate pulse generation characteristics is used. A wide variety of types of mine with mechanically-activated and electrically-activated fuses can be cleared remotely by the Rayleigh surface wave method.

Title: Rapid float
Inventor: HENSON DENNIS RAYMOND
IPC: E03D1/33
Filed: 1998-04-08
Abstract: As liquid is drawn off tank 6 the float 5 and arm 4 will fall, opening valve 3 partially. Liquid is discharged into container 1 (FIG 2). When container 1 is filled to overflowing the weight of liquid therein causes float 5 to sink further into main body of liquid in tank 6, rapidly opening valve 3 fully (FIG 3). Float 5, now less buoyant with its extra weight, will rise as tank 6 fills, until the container 1 spills liquid from of the end thereof, which end is adjacent valve 3 (FIG 4). Float 5 now more buoyant, with less weight of liquid to lift, will rise shutting off valve 3 quickly (FIG 1). Float 5 with container 1 can be affixed to, or part thereof a lever that is attached to a valve body by a pivot.

Filed: 1998-10-22
Abstract: A clamp for clamping two concentric tubes, typically two concentric tubes in an oil or gas well, has two axially movable tapered components 6,7 which can be pulled over one another in an axial direction to provide a contraction of internal diameter which grips the smaller diameter tube. In one embodiment, a spacer 12 is fined to allow the tapered components to be held apart until the tubes have been correctly positioned. The spacer is then removed, and the tapered components are drawn together to effect the clamping. A hydraulic ram 5 can be provided to separate the tapered components should readjustment be required. In another embodiment, the larger diameter tube is made with a relatively thin wall, so that it can be distorted inwards to grip the smaller tube
