Title: Wireless downhole electromagnetic signal transmission in a bore hole
Inventor: GARDNER WALLACE R
IPC: E21B47/12
Filed: 2007-04-27
Abstract: A downhole telemetry system for transmitting electromagnetic signals wirelessly in a bore hole comprises a surface modem (230) coupled to an antenna and a downhole modem (220) coupled to an antenna (201). The modems (220, 230) communicate using discrete multitone (DMT) modulation over a first set of frequency subchannels for uplink communications to a surface computer (234) where the telemetry data may be processed. Bidirectional communication may be implemented, whereby downlink communications are effected over a second set of frequency subchannels. The number of bits transmitted over a frequency subchannel is determined in a configuration process and may be determined dynamically so as to optimise the communications for the downhole conditions, improving telemetry data rate and reliability.

Title: High voltage compact x-ray generator for oil well formation analysis
Inventor: WRAIGHT PETER DAVID
IPC: G01V5/12
Filed: 2007-06-26
Abstract: An apparatus and method for determining the density and other properties of a formation surrounding a borehole using a high voltage stable compact x-ray generator. The x-ray source is capable of providing radiation with energy of 250keV and higher while operating at temperatures greater than 125{C. The x-ray generator comprises high voltage generators 302, 304 connected to electron emitter 314, and target 307 respectively. The high voltage generators 302, 304 are folded to minimize the length of the tube. Radiation (708, Fig.7) is passed from an x-ray generator (706, Fig.7) into the formation; reflected radiation is detected by a short spaced radiation detector (704, Fig.7) and a long spaced radiation detector (702, Fig.7). The output of these detectors is then used to determine the density or photoelectric effect of the formation. A reference radiation detector (812, Fig.8) monitors a filtered radiation signal. The output of this detector is used to control at least one of the acceleration voltage and beam current of the x-ray generator.

Title: Desalination method
Inventor: BELL IAN STEPHEN
IPC: B01D1/22
Filed: 2008-01-04
Abstract: The present invention relates to a method and apparatus of producing water from a saline solution ie desalination of salt water to produce pure water. The method comprises the steps of: 1) rotating the saline solution 210 in order to create a surface on the saline solution due to centrifugal forces acting on the saline solution; 2) slidingly engaging a frictional element, such as a jet of air, with the surface 322 in order to generate heat within the surface due to the friction between the frictional element and the surface, to cause water to vapourise from the surface of the saline solution; 3) moving the vapourised water away from the surface; and 4) condensing the vapourised water into a liquid. The frictional forces are claimed to be generated by either air or a skid biased into engagement with the surface of the water. The evaporator further comprises a nozzle arranged to propel air at the surface of the liquid and a gas outlet arranged to remove the air with the entrained vapour. The nozzle pipe and the outlet pipe are arranged opposite one another. The air may additionally carry plastic granules which are entrained in the gas in order to increase the claimed frictional effects. Centrifugal forces acting upon the saline solution provides a surface which is sufficiently stable to enable the frictional element to rub up against and frictionally work upon the surface to generate the heat required without the surface disintegrating.

Title: A Treatment method for Effluent
Inventor: DARGUE ANDY
IPC: C02F1/58
Filed: 2008-06-06
Abstract: A method for the removal of contaminants from effluent and in particular, to a method for the removal of anions, such as sulphates (sulfates), from trade effluents. The method comprises steps of adjusting the pH of the effluent to an acidic first value of less than or equal to 2 followed by adding a source of aluminum and then adjusting the pH of the effluent to a second alkaline pH value which is more than or equal to 10. A source of calcium ions is also added to the effluent either during or after adjusting the pH to more than or equal to 10 such that adjustment of the pH of the effluent to the second alkaline value can be caused by the addition of the calcium ions or be adjusted independently by a reagent. In the application of the method to remove sulphates, a calcium aluminum sulphate oxide is formed and removed from the solution by filtering. Ideally, the first pH value is less than or equal to 1.3 and the second pH value is greater than or equal to 11.5. The rate of reaction can be increased by providing oscillatory pressure such as ultrasonic energy (sonication) or by irradiation.

Title: Correcting image defects using a gradient measure
Inventor: RE SOBASTIEN CLODI
IPC: G06T5/00
Filed: 2009-08-21
Abstract: The invention concerns processing images to correct defects or artefacts occurring as a result of transmission or storage. It aims to identify inappropriate operation of image correction due to "false alarms" or incorrect identification of defects which in turn allows a higher-sensitivity detection process to be used and therefore more "genuine" defects to be corrected. The invention involves control of image correction by a gradient measure which is evaluated over the periphery of an image region to be corrected. An accumulated gradient measure is formed along the periphery of the region to be corrected and evaluated for the region both with and without correction. The application of correction to the region is then controlled by the result of the comparison between said measure for the corrected and non-corrected regions with the correction process being inhibited where the gradient measure for the corrected image would be higher than that for the uncorrected image.
