Patent GB-2262117-A (GB)
Title: Conformance control in underground reservoirs
Inventor: SNOWDEN MARTIN JOHN
IPC: E21B33/138
Filed: 1992-11-30
Abstract: A method for conformance control of a reservoir where high formation temperatures are encountered comprises the steps of   (a) injecting at ambient temperature into the formation a latex solution containing particles which flocculate, shrink and harden at higher temperatures, and a solution of an ionic compound as a promoter, (b) allowing the solution to flow through a zone or zones of relatively high permeability in the formation under increasing temperature conditions, and (c) allowing the latex particles to flocculate, shrink and harden at a location where the temperature is sufficiently high to promote this effect.   When the particles flocculate, shrink and harden, they form a more effective blocking agent than the dispersed, expanded and softer particles.

Title: Vehicle body panel protector
Inventor: TYERS DAVID ANTHONY
IPC: B60J11/00
Filed: 1993-06-01
Abstract: A panel protector assembly permanently fitted to vehicle body panels. Four panel protectors are normally required to adequately protect a vehicle. The panel protectors are for use when the vehicle is parked where other vehicles are likely to park adjacent. Typically, protective absorber 13 is physically extended from shroud 20 by means of grip bar 17 and attached at a fixing point by clips. Once the protective absorbers are extended the doors of an adjacently parked vehicle are unable to make contact with the vulnerable vehicle body panels covered by the protective absorbers. Before the vehicle is driven, the protective absorbers 13 are retracted under tension of a spring 7. The grip bars are located in the body shrouds. To prevent any protective absorbers being left extended whilst the vehicle is being driven an electrical warning device is installed to indicate a protective absorber in the extended position. <IMAGE>

Title: A multi-step book manufacturing process including aligning and weighing steps
Inventor: LARKIN OLIVER
IPC: B42C19/00
Filed: 1993-08-23
Abstract: In a book manufacturing process a number of sets of printed sheets are prepared at a printing station, each set of sheets being associated with a particular book section which is formed by folding the sheets. Sets of different book sections are collated. The collated book sections 19 are then correctly aligned by pushing them over a roughened surface 62 which frictionally engages a lower side edge of each book section resisting forward movement of the book sections by a pusher arm 60, urging an associated end edge of each book section against the pusher arm and into alignment. The aligned book sections are then joined by adhesive at a binding station and wrapped in a cover to form a book. After drying the adhesive, the free edges of each book section are trimmed. Each book is then weighed (80, Fig. 10) to check it is complete and that no book sections have been omitted. As an alternative to the roughened surface 62, the collated book sections 19 may be frictionally engaged by a flap or arm, mounted above the conveyor base plate 58, which carries a friction element. <IMAGE>

Title: Gaseous suspension particle size measurement
Inventor: PYE JOHN ALBERT
IPC: G01N21/53
Filed: 1991-03-19
Abstract: A radiation source 5 projects a beam of infra-red or visible radiation into a test space containing the gaseous suspension 7 to be measured. A plurality of sensors 6, 6' are arranged at respective angles to the intersection of the beam with the test space and respond to radiation scattered by particles in the suspension. The particle size, or size distribution, is determined from the amounts of radiation detected by the respective sensors. The test space may be defined by the interior of a transparent tube through which the suspension is passed, the source and sensors being disposed on the exterior. An auxiliary sensor may compensate for build-up of particles on the tube walls. Alternatively the beam may be directed into the exhaust plume of a motor vehicle, no physical containment being employed. <IMAGE>
Patent GB-2286287-A (GB)
Title: ESD protection using more than one ground network
Inventor: MOTLEY GORDON
IPC: H01L27/088
Filed: 1995-01-20
Abstract: ESD protection for an integrated circuit having a dirty ground is increased by including an SCR (31, 32) or other protection device from dirty ground to each pad (24, 25) whose driver (17, 20) uses dirty ground (DGND). The SCR or other protection device (if triggerable) is triggered by a sensing circuit that is referenced to dirty ground. If there is more than one dirty ground then the one that is used is the dirty ground that is associated with the pad to be protected. Pads not using a dirty ground may also be protected with respect to a dirty ground. A p-type substrate library cell for ESD protection of a pad may be developed that includes a first SCR from the pad to ground, a trigger circuit referenced to ground for the first SCR, a second SCR from the pad to a dirty ground, and a trigger circuit referenced that dirty ground for the second SCR. The trigger circuit for the library cell uses the presence or absence of VDD to provide high or low threshold voltages for triggering the SCR. For n-type substrates where VDD and DVDD take the place of GND and DGND, respectively, on-chip VDD cannot be allowed to select the threshold. An instance of a separate and isolated VDD brought into the IC on its own pin, and not otherwise used internally, can be used as the switching signal. <IMAGE>

Title: Video data compression system
Inventor: GILLARD CLIVE HENRY
IPC: H04N19/895
Filed: 1997-06-10
Abstract: A video data compression system uses a wavelet transform circuit (580) but otherwise operates in the manner of an MPEG II compression system. The compressed data is stored on a medium such as a tape by e.g. a digital video tape recorder (3), which medium and recorder may subject that data to errors by virtue of head failures and/or tape defects. Means (5) are provided to produce concealment data indicative of the form of concealment to be used if data is lost during reproduction. A variety of concealment techniques are used. Some of the transformed data is frequency inverted during transformation. Such data is subject to high pass filtering to conceal errors. Concealment data indicates the most appropriate form of concealment to be used in the event of an error and is produced before recording and recorded with the data. The concealment data is recorded on a track different to the track of the data with which it is associated. The concealment data may be produced by trial concealments and/or by providing predetermined concealment data for different forms of data.
