Title: I.C. engine variable valve timing device
Inventor: GRAHAM ALAN JOHN
IPC: F01L1/344
Filed: 1984-02-07
Abstract: To vary the position of an outer driven member 4 relative to the inner driving member 2 chambers 5 defined between the members are filled with the desired amount of oil supplied under pressure from the engine oil pump (not shown) via fill and dump valve 7. In this way the outer member 4 is advanced due to the hydraulic action of the oil against the driven member 2 thus overcoming the reflected loading on the outer member 4 due to the camshaft compressing the valve springs. <IMAGE>

Title: Nuclear magnetic resonance method and apparatus
Inventor: BAILES DAVID ROBERT
IPC: G01N24/08
Filed: 1985-06-26
Abstract: A method, and an apparatus for performing the method, are described, for imaging a region of a body using NMR in which part of the region is moving with a motion such that its displacement with respect to time is a nonmonotonic function during the time period over which NMR data signals are collected. The data signals are collected in an order dependent on the motion such that motion artefacts are reduced. Thus where motion is in a direction along which phase encoding is produced by application of a different gradient integral in each cycle, a probability distribution of displacement d is evaluated, & a look-up table (Fig 5) is produced such that the variation of d with gradient integral is the best approximation to a monotonic function. Just before each cycle, d is measured and the nearest unused value of gradient integral is selected from the look-up table, resulting in an image of the stationary part of the slice together with a smeared image of the moving part. <IMAGE>

Title: Borehole extraction of minerals
Inventor: PIKE WILLIAM CARILL
IPC: E21B43/29
Filed: 1986-05-29
Abstract: A method for the extraction of a mineral from an underground unconsolidated formation comprises the steps of:   (a) driving a casing through the overburden and into the mineral bearing pay zone, (b) passing a high pressure water jet head and associated supply line down through the casing so that an annulus is formed between the casing and the supply line and the jet head projects just beyond the casing, (c) directing water from the jet head into the pay zone to cause disintegration of the latter, (d) recovering desired product through the annulus between the piping and the casing, (e) moving the jet head to a different level in the pay zone when the previous level is effectively exhausted, and (f) moving the casing in association with the jet head so that the latter remains in the same operating position with respect to the casing with the jet head projecting just beyond the casing. The method is particularly suitable for extracting bitumen from tar sands. l
Patent GB-2193621-A (GB)
Title: Plant support line
Inventor: MAZURA JAN
IPC: A01G9/12
Filed: 1986-07-29
Abstract: The line comprises a series of loop regions 3 and a series of junction regions 2 arranged alternately along the length of the line. The line may be formed of a series of loops (e.g. cut from the legs of ladies' tights) which are joined together at the junction regions. It may also be formed of a pair of parallel strings which are knotted together at intervals, or by a pair of parallel plastics elements joined by a series of heat welds. The line can be used to support growing plants such as cucumbers and does away with the need for separate wire ties. The growing tips are gently inserted through the loops which expand as the plant grows, thus avoiding strangulation of the plant. <IMAGE>

Patent GB-2201860-A (GB)
Title: Compressed air audio speaker
Inventor: WRIGHT LUKE FRANK
IPC: H04R23/00
Filed: 1987-02-10
Abstract: A compressed air audio speaker consists of a cylindrical speaker drum having two parallel skins attached to either end. The system also consists of air tubing to transfer and carry the sound waves. The system has an alternating power supply connected to a copper coil in order that it will produce an alternating magnetic field around a piston fitted with a compression ring that has a built in magnet. The alternating field in the copper coil causes the piston to reciprocate inside an air carrying sleeve. The container flow of alternating electricity allows the piston to transfer sound waves via the air tubing to the sound speaker. <IMAGE>

Title: Optical communication system
Inventor: GODDARD ISOBEL JENNIFER
IPC: H04B10/275
Filed: 1988-11-11
Abstract: In an optical fibre LAN each node is coupled to a central star-coupler (SC) via optical fibres (F1, F2) so that the system is a star network. However, each node in use has its receiver tuned to light of the wavelength sent out by the preceding node. Hence the system works like a ring. To minimize risk due to failure of the star-coupler assembly, two such assemblies each separately coupled to the nodes can be used, (Fig 4 not shown). Each star-coupler assembly is built up from 2x2 couplers. <IMAGE>
