Title: Device for the aeration and de-stratification of water using wave-driven air compressors
Inventor: BROOKS COLIN
IPC: F03B13/00
Filed: 1994-05-10
Abstract: A tethered buoy system generates compressed air from the motion of the floating ring 6 relative to the main body 9 and the tension induced in the mooring and anchor lines 11 and 12 by the spring piston 10. This compressed air is fed into the bottom of the vertical tube 23. Passage of the air through the tube 23 induces a flow of water up the tube to the surface layer. As a result of this action aeration occurs and a movement of water from the lower level to the surface layer. The main body 9 houses bellows (4, Fig. 2) which are caused to alternately expand and contract through oscillation of float ring 6 thereby forcing air via one-way valves (8, Fig. 2) into the air lines 14. In an alternative arrangement the bellows are driven by a pulley wheel (16, Fig. 3) over which runs the mooring line 11. <IMAGE>

Title: Enhancement of hot workability by use of thermal spray coatings
Inventor: RUSSO PATRICK A
IPC: C23C4/18
Filed: 1992-12-18
Abstract: The present invention relates to a process in which a metal or metal alloy is thermal spray coated onto a base alloy material prior to hot working. More specifically, the invention relates to the use of plasma coating of titanium over a titanium alloy plate for improved hot workability. This combination allows the crack-sensitive base alloy to be rolled with a minimum of surface and edge cracks. In addition, by using a plasma sprayed titanium coating there is a reduction in the roll force required to reduce the material during the hot working process. The titanium coating layer being at least 0.25 m.m. thick.

Title: Measurement of three dimensional flow velocities
Inventor: RAFFEL MARKUS
IPC: G01P5/18
Filed: 1995-01-31
Abstract: Contactless measurement of three dimensional flow velocities is made by seeding a flow with tracer particles 7, repeatedly illuminating a planar interrogation volume, imaging the volume onto a photosensors 9, 10 for recording pictures of the volume, and determining the flow velocities from the pictures. The interrogation volume comprises two parallel partial volumes 5, 6 illuminated so that the pictures of different partial volumes are distinguishable eg by using differently polarised beams. Velocities are calculated using an autocorrelation function of a single picture of a partial volume or a cross-correlation function between two separate pictures of the same partial volume, and using a cross-correlation function between two pictures of different partial volumes. The sign of the out-of-plane component of the local flow velocities is determined from the location of a peak of the crosscorrelation function between the pictures of two different partial volumes, and the magnitude from the peak heights of both correlation functions. <IMAGE>

Title: GPS apparatus
Inventor: MAEDA HIROAKI
IPC: G01S19/20
Filed: 1995-09-21
Abstract: A ground station receives a GPS signal from a GPS satellite, obtains a distance error component included in the GPS signal, produces a pseudo-GPS signal which contains data regarding the distance error component and at least position data, and which has a frequency differing from the frequency of the GPS signal, and sends the pseudo-GPS signal to a receiving antenna on a vehicle. Therefore, the receiving antenna receives the GPS signal from the GPS satellite and the pseudo-GPS signal from the sending section. The GPS signal and a local oscillator signal LGPS sent from a local signal producing section are mixed and converted into a base band signal, and the pseudo-GPS signal and a local oscillator signal LPSEUDO-GPS send from the local signal producing section are mixed and converted into a base band signal of the same frequency. The base band signals are subjected to tracking processing, thereby obtaining data, and the position obtained from the GPS signal is corrected on the basis of the obtained data, thereby producing accurate navigation data. <IMAGE>

Title: Sequence analysis of polysaccharides with exoglycosidases, following partial depolymerisation
Inventor: GALLAGHER JOHN THOMAS
IPC: C12Q1/34
Filed: 1995-10-30
Abstract: In a method of analysing saccharide material such as glycosaminoglycans (GAG's) to determine the sequence of monosaccharide units in oligosaccharide chains thereof, the saccharide chains are end referenced, e.g. by labelling or tagging at their reducing ends, and the saccharide material is subjected to a controlled partial depolymerisation using a selective scission reagent, for example low pH nitrous acid, which cleaves internal glycosidic linkages in accordance with a known linkage specificity so as to produce a mixed set of saccharide chain fragments having different lengths ranging throughout the full spectrum of possible lengths for the particular glycosidic linkage specificity of the selective scission reagent employed. Samples of the mixed set of saccharide chain fragments are then treated with selected exoenzymes including exoglycosidases that cleave only particular glycosidic linkages at the non-reducing end of saccharide chains and exosulphatases that selectively remove sulphate groups from monosaccharide residues at the non-reducing end of saccharide chains. These exoenzymes are applied to the samples either singly or in combination in accordance with a predetermined strategy. The treated samples are then analysed, conveniently by polyacrylamide gel electrophoresis (PAGE) to detect the chain fragments present which have a reducing end derived from the reducing end of the corresponding chain in the original seccharide material. Using PAGE, preferably gradient PAGE, the different samples are run in parallel tracks of the gel and a migration banding pattern is obtained that provides information which enables the monosaccharide sequence in the original saccharide material to be deduced.

Title: Low leakage electrostatic discharge protection system
Inventor: ORCHARD-WEBB JONATHAN HARRY
IPC: H01L27/02
Filed: 1998-02-21
Abstract: An integrated circuit 16 is protected against ESD events by means of an arrangement having a high voltage diode 32 connected between an input pad 10 and a positive supply 12, a high voltage diode 34 connected between the input pad 10 and a negative supply 14 and an element 36 connected between the positive and negative supplies 12, 14 and capable of conducting in both directions during an ESD event. The element 36 may be a diode 36 and has a reverse breakdown voltage exceeding the difference between the supply voltages 12, 14. The diode 36 may be a fast acting lateral npn diode with snap back action under reverse bias. The diodes 32, 34 have a much greater reverse breakdown voltage than diode 36 and may be Schottky diodes, avalanche diodes or MOS-transistors. Field plating (Fig.4) may be used to increase the reverse breakdown voltage of diodes 32, 34. Alternatively, special diffusion (ie. p-base) may be used. Deep junction diodes (Fig.5) may also be used. Additional high voltage diodes 38, 40 may be connected to a second input 10', so that in the event of a discharge between inputs 10, 10' with positive charge on input 10, a conductive path would follow diodes 32, 36, 40, whereas if electrostatic polarity was reversed the conductive path would follow diodes 38, 36, 34.

Title: Distance measurement device
Inventor: ODA HAJIME
IPC: G01S17/18
Filed: 1995-09-28
Abstract: Device 1 measures the distance to target T and assigns it to one of a plurality of range bands. The device sets the boundaries between the range bands using initial distance measurements to targets, eg an operator's hand, placed at the boundaries when switches 3a, 3b are pressed. The measurements are stored and the device then compares subsequently measured distances with these initial measurements. A timer 7 provides a delay between the pressing of switches 3a, 3b and the commencement of an initial distance measurement; this gives an operator time to move to a desired position when setting a boundary. A single initial measurement may be used to set two boundaries (figs 7, 9) and this allows the device to be easily reset when moved. The device can be used for detecting articles on conveyor belts (fig 12).
