Patent GB-2296926-A (GB)
Title: Method and apparatus for sealing and transferring force in a wellbore
Inventor: VAN BUSKIRK RICHARD GLENN
IPC: E21B33/134
Filed: 1993-10-04
Abstract: A wellbore (1) is at least partially obstructed with a partition or obstruction member (5). A fluid slurry of an aggregate mixture of particulate matter is pumped into the wellbore adjacent the partition or obstruction member. The aggregate mixture of particulate material contains at least one component of particulate material, and each of the at least one particulate material components has an average discrete particle dimension different from that of the other particulate material components. Fluid pressure then is applied to the aggregate material, and fluid is drained from the aggregate material through a fluid drainage passage in the partition or obstruction member. The fluid pressure and drainage of fluid from the aggregate mixture combined to compact the aggregate mixture into a substantially solid, load-bearing, force-transferring, substantially fluid-impermeable plug member (11), which seals a first wellbore region from fluid flow communication with a second wellbore region. The plug member is easily removed from the wellbore by directing a high-pressure fluid stream toward the plug member, thereby dissolving or disintegrating the particulate material of the plug member into a fluid slurry, which may be circulated out of or suctioned from the wellbore.

Title: Fibre-optic photoelectric beam device
Inventor: FUERSTENAU NORBERT
IPC: G01B11/04
Filed: 1996-05-02
Abstract: A photoelectric beam device comprises a light source 2, a monomode optical fibre 12, a transmitting optical unit 18, a reflector 24 and a photodetector 28, where the transmitting unit 18 comprises a collimator e.g. a graded index lens or rod lens 20 and a beam expansion optical unit 22 e.g. a telescopic optical unit. Preferably a fibre-optic directional coupler 4 is arranged between the light source 2 and the monomode fibre 12 so that the optical signal reflected back from the reflector 24 to the transmitting optical unit and refocused into the fibre 12 is conducted to the photodetector 28. Two such devices may be arranged with parallel beams to determine the speed, direction and length of an object passing transversely to the beams. Alternatively this may be done by analysing the shape of the output signal of a single beam device that has an attenuator in half of the beam.

Title: Radiotelephone proximity detector
Inventor: BARRETT STEVEN
IPC: H04M1/724
Filed: 1996-10-23
Abstract: A radiotelephone proximity detector comprises of a telephone proximity unit 16 associated with a mobile telephone and a belt clip proximity unit 46 associated with a user, both containing transceivers 74, 54 respectively. Transmitter 76 produces a master signal S2 to be received and demodulated by a receiver 58 which communicates the strength of the signal to a controller 52. If the receiver does not receive a signal within a predetermined time interval or the magnitude of the signal received is less than a given value, an alarm is actuated indicating that the two units are separated by more than an acceptable distance, and normal operation of the telephone becomes inhibited. If an appropriate signal is received, the slave unit responds by sending a response signal S1 which is received and analysed in similar fashion by receiver 78. Both units can be coupled via contacts 62, 82 which places the units in a standby mode.

Patent GB-2332028-A (GB)
Title: Releasable push-fit tube coupling
Inventor: DEASON WILLIAM SYDNEY
IPC: F16L37/098
Filed: 1997-12-05
Abstract: The coupling of the type having a body 1 and a tube-gripping collet 3 comprising a release sleeve 6, is characterised by the provision of an elastomeric cap 11 retained by the release sleeve 6. The cap 11 has an annular end surface 14 that sealingly abuts the outermost end of the body 1, while the outermost end 15 of the cap 11 defines an aperture 16 through which a tube 5 coupled to the coupling sealingly extends. The cap 11 therefore completely seals the interior of the coupling against the ingress of foreign matter which otherwise could impair releasability of the coupling.

Title: Expanding and supporting an end of a plastics pipe prior to pipe coupling
Inventor: BALLS FRANK CHARLES
IPC: F16L21/00
Filed: 1998-03-04
Abstract: A supporting pipe-like insert sleeve 4 is disposed within the pipe end 2, e.g. of a liner pipe, the sleeve having a discontinuity in its circumference which extends axially along it so as to define two elongate edges 6,8, the elongate edges 6,8 when inserted into the pipe end 2 overlapping such that one 8 is radially within the other 6. Expanding means is disposed within the insert sleeve 4 and radially expands it against the inner surface of the pipe end so as to expand the pipe end radially, the radial expansion of the insert sleeve being continued until there is no overlap between the elongate edges 6,8, such that the elongate edges 6,8 meet and lock against circumferential, and hence radial, contraction. The pipe end 2 is then inserted into a coupling member, e.g. on electrofusion coupler.

Title: Oil well heater cable
Inventor: NEUROTH DAVID H
IPC: H05B3/56
Filed: 1997-10-08
Abstract: A heater cable is strapped alongside tubing in a well to heat the production fluids flowing through the tubing. The heater cable has three copper conductors surrounded by a thin electrical insulation layer. An extrusion of lead forms a protective layer over the insulation layers. The lead sheaths have flat sides which abut each other to increase heat transfer. A metal armour is wrapped around the lead sheaths of the three conductors in metal-to-metal contact. Three phase power is supplied to the conductors, causing heat to be generated which transmits through the lead sheaths and armour to the tubing.

Title: Apparatus and method for film transport of an APS camera
Inventor: KIM BYUNG-SU
IPC: G03B17/42
Filed: 1998-07-15
Abstract: An apparatus for transporting film within an APS camera includes a perforation sensor, a controller, a film transporter, and a motor M. The controller receives signals from the perforation sensor, and controls the film transport in response to the electric signal. The controller, also controls the film transporter to rewind the film and then wind the film to a predetermined position. During winding the controller, counts a time period during which a perforation is not sensed by the perforation sensor, and compares the time period with a predetermined time. The controller then controls the film transporter to wind the film so long as the time period is less than the predetermined time; and stop the winding of the film at a position when a state of a signal from the perforation sensor changes, when the time period exceeds the predetermined time. Preferably the rewinding stops after the perforation sensor has stopped twice.

Title: Secure token-based document server
Inventor: PENDLEBURY DAVID
IPC: G06F17/30
Filed: 1998-09-30
Abstract: A system is presented for transmitting document references or tokens between users of integrated wireless and wire-based communication services. The system includes workstations, files servers, printers and other devices coupled to a wire-based network. Mobile computing devices are coupled to the wire-based network through either IR (infrared) or RF (radio) transceiver gateways. Each mobile computing device appears to hold a user's collection of documents: the device is programmed to receive, transmit, and store document tokens. The system includes a token-enabled document server that uses digital signatures to provide secure transfer of document tokens between users of the mobile computing devices and email clients. The token-enabled document server operates independent of the identity of the holder of the document token. Only the issuer of the document token needs be registered with the signature based document server to properly authenticate document tokens.

IPC: H04N5/374
Filed: 1999-02-24
Abstract: In an XY address type solid state pickup, the reading out of signals from pixels 1 in one row Vm+k is performed simultaneously with the shutter operation of pixels in another row Vm. The pixels in adjacent rows may also be spaced in the line direction. A read scanning pulse and a shutter scanning pulse are output from both a horizontal 7 and a vertical 3 scanning circuit. Phases of the shutter and read scanning pulses preferable do not overlap. The shutter pulses may be controlled so that the accumulation time of each pixel is constant Such a pickup, which may include MOS or CMOS elements, permits high shutter speed with low switching noise.
