Title: Liner setting tool with radial washout ports
Inventor: HOWLETT PAUL
IPC: E21B34/12
Filed: 2001-01-12
Abstract: A liner setting tool (1) for running a liner (11) or casing into a borehole (9) has an elongate body (2) for attachment to the liner (11) or casing. Rotation of the body (2) relative to the liner (11) allows radial outlets (6) present on the body (2) to move from a position where they are closed by the liner (11) to a position where they align with ports (12) on the liner (11) and are therefore open. Such an arrangement allows cementing to occur in a conventional way, where cement is pumped through outlet (8) of the tool and also allows the bore (9) to be cleaned by pumping cleaning fluid through ports (6). Seal rings may also be present to restrict flow of fluid between the tool (1) and the liner (11).

Title: Downhole cleaning tool with shear clutch
Inventor: HOWLETT PAUL
IPC: E21B37/02
Filed: 2001-01-22
Abstract: A cleaning tool <B>1</B> for cleaning casing within a well bore comprises an upper <B>3</B> and lower <B>4</B> sleeve which are mounted on a work string <B>2</B> via ball bearings <B>5</B> to enable them to rotate independently of the work string <B>2</B>. The upper <B>3</B> and lower <B>4</B> sleeves limit the axial movement of a lantern <B>6</B> on which cleaning members <B>7</B> are mounted The lower sleeve <B>4</B> has a recess for receiving the lantern <B>6</B> and within which a clutch <B>9</B> sits. In normal operation the lantern <B>6</B> sits between the upper <B>3</B> and lower <B>4</B> sleeves and is able to rotate freely of the work string <B>2</B>, however when the work string <B>2</B> is picked up, friction from the casing wall will encourage the lantern <B>6</B> to engage the clutch <B>9</B>. With the clutch <B>9</B> engaged the lantern <B>6</B> will rotate with the work string. The clutch <B>9</B> is held to the work string by a shear pin so that if the resistance to rotation of the lantern <B>6</B> exceeds a given load the shear pin will break allowing the lantern <B>6</B> to rotate freely with respect to the work string <B>2</B> even if the clutch <B>9</B> is engaged.

Title: Carrier generation and suppression in an 8PSK transmitter, and subsequent carrier recovery in an 8PSK receiver
Inventor: BEECH BRIAN HERBERT
IPC: H04L27/34
Filed: 2002-05-22
Abstract: A carrier signal is deliberately introduced into a PSK modulated signal by use of asymmetry in the constellation, for example by moving one point 1 on the circle to the origin 9. The resultant carrier is suppressed before transmission by rotating the phase of each successive symbol using a pseudo-random sequence (figure 4). The carrier is recovered at the receiver by use of a corresponding derotator (51, figure 5). The receiver PRBS generator is synchronized by sending a special sequence of symbols which is distinguished from normal data traffic by a lower average magnitude. The low overall magnitude is due to inclusion of many symbols of low or zero amplitude. Carrier recovery in this system is less subject to phase noise and does not exhibit false lock.

Title: Cementitious mixtures
Inventor: KARIHALOO BHUSHAN LAL
IPC: B28C7/00
Filed: 2002-04-18
Abstract: A method of producing a cementitious mixture initially comprises thoroughly dry mixing the coarsest constituent of the mixture with the finest: this process is repeated until all of the sand, microsilica and cement has been added. In this manner a very even distribution of the different sized particles is achieved, since the voids between adjacent larger particles are filled with smaller particles and thus the produced concrete has a high strength. Following the dry mixing, water and superplasticiser is added. Less water than is conventionally used is required since the mixture is more densely packed. In order to further strengthen the mixture and to greatly enhance its energy absorption capacity, reinforcing fibres having different lengths may be added prior to adding the water and following mixing of the granular materials. The fibres are added by placing them on an apertured surface which is agitated to cause the fibres to fall through the apertures in a random orientation.

Title: Controlling imaging array exposure using supplied voltage.
Inventor: BORG MATTHEW M
IPC: H04N5/335
Filed: 2004-03-19
Abstract: A system comprises an imaging pixel array 203, such as a complementary metal oxide silicon (CMOS) array, and an exposure level determining means 207 that generates a signal indicating the level of exposure of the sensor array. A voltage supply adjuster 206 then operates to vary the voltage supplied to the imager in response to the exposure level indicator. The voltage supply is increased for higher exposure levels, expanding the dynamic range of the array, and decreased for lower exposures, accordingly reducing pixel noise levels. The device for determining exposure may comprise a programmable gain amplifier (PGA 301, Figure 3A), analogue to digital converter (ADC, 303) and gain controller (305). A comparator (207, Figure 3B) may be used to compare digitised signals output from the array with a target, threshold value (309).

Title: Managing power requirement changes by inserting dummy operations
Inventor: WILLIAMS EMRYS
IPC: G06F1/32
Filed: 2004-07-15
Abstract: The power requirements of a semiconductor device such as a processor are monitored. When a change in power consumption is detected, dummy instructions are inserted into the sequence being executed to smooth or limit the change. This prevents voltage spikes. The null instructions may be high current instructions if the power use is falling or low current instructions if the power use is rising. The power requirements may be calculated by estimating the power requirements of the instructions to be executed. It may take into account in the state of the processor. The estimate may be made over a number of cycles of the processor. It may use power fluctuation limits or a model of the power supply to determine when to insert no-operation instructions. A look-up table may be used to estimate the power requirements of each instruction.
