Title: Downhole telemetry system using DMT modulation
Inventor: HUCKABA BRUCE S
IPC: G01V11/00
Filed: 2002-01-25
Abstract: A downhole telemetry system having discrete multi-tone modulation and dynamic bandwidth allocation comprises a surface transceiver, a cable, and a downhole transceiver coupled to the surface transceiver via the cable. The downhole transceiver communicates to the surface transceiver using discrete multi-tone (DMT) modulation to transmit telemetry information over a set of frequency subchannels allocated for uplink communications. The surface transceiver may likewise communicate to the downhole transceiver using DMT modulation to transmit information over a set of frequency subchannels allocated for downlink communications. The number of uplink and downlink communications subchannels is preferably variable and preferably can be changed depending on the operating mode of the system (Figs 6A-6C, not shown). This allows additional subchannels to be allocated for downlink communications during programming and configuration of the downhole equipment, and additional subchannels to be allocated for uplink communications during normal logging operations. Applications include borehole logging.

Title: A system for identifying, locating and displaying the location of vehicle obstructions on the highway
Inventor: ALEXANDER PAUL
IPC: G08G1/16
Filed: 2002-04-27
Abstract: A vehicular obstruction location identification system, including one or more obstruction identifier module 1, a central control unit 2 and a remote control unit 3, all of which are in communication via communications devices 8, 11, 13, to identify the location of a vehicular obstruction. One or more obstruction identifier module 1 is placed anywhere locally, nationally or globally, each of which, on sensing a vehicular obstruction automatically generates a code containing at least a unique identifier and then communicates the code to a central control unit 2 via communications devices 8, 11. On receiving the aforementioned code, the central control unit 2 automatically looks up the location of the vehicular obstruction in a database 10. The central control unit 2 communicates the location of the vehicular obstruction via communications devices 11,13 to a remote control unit 3.

Title: Assay Apparatus
Inventor: HODGES MICHAEL
IPC: G01N21/25
Filed: 2002-06-11
Abstract: Assay apparatus 1 comprises a reading sensor 6 and lamp 7. Directly beneath the sensor 6 and lamp 7 is a circular filter wheel 8 mounted for rotation on spindle 9 and including filter apertures 10 to restrict light transmission to preselected wavelengths. The filter wheel 8 can be rotated in a stepwise fashion to bring diametrically opposed filter apertures 10 into register with the reading sensor 6 and lamp 7. Beneath the filter wheel 8, two upright tubes 12, 13 are linked by diagonally extending tubes 14, 15. Extending from the upright tubes 12,13 are two rotatable optical fibre devices 16. The series of tubes contain optical fibres and combined with optical fibre devices 16 provide two light paths carrying light from the lamp 7 to a plurality of reaction vessels 3 and two light paths carrying light from said vessels to the sensor 6. In use, the lamp 7 is turned on and one of the optical fibre devices 16 is turned to a blank position so it is not aligned with an aperture 20, while the other optical fibre device is positioned over one of said apertures 20, which are arranged radially with the path of the devices. Light from the lamp passes through the optical fibre device 16 into an optical fibre and is then absorbed by a sample in one of the vessels 3, while light emitted from the sample returns to the reading sensor 6. The device is rotated through a complete cycle and then set to a blank position while the process is repeated with the other device 16.

Title: Gravel packing tool with fluid bypass to maintain wellbore pressure
Inventor: BIXENMAN PATRICK W
IPC: E21B34/00
Filed: 2002-08-09
Abstract: A gravel pack apparatus 10A includes a bypass mechanism 300 to maintain the portion of well being packed in an overbalanced condition, i.e. well pressure greater than formation pressure. The bypass mechanism incorporates at least two alternate fluid pathways and is operated by a remote signal such as a pressure pulse. With the bypass in a first position, pressure from the annulus 17 is communicated to the target section 9 of wellbore, whilst with the bypass in a second position, pressure from inside the tubing string 8 is communicated. The fluid pathways bypass a packer 7 that seals the well annulus to contain the proppant (gravel containing) fluid, and flow through the lower string 101 is governed by a ball valve 56 and a crossover device 312. Use of this apparatus protects the filter cake by reducing pressure drops caused by swabbing effects resulting from movement of the tool during a gravel pack operation.

Title: Method of regulating the feed force during drilling
Inventor: KOCH ELMAR
IPC: E21B44/06
Filed: 2002-10-03
Abstract: In a method of regulating the feed force of a drilling device having a hydrostatic borehole motor at the end of a linkage provided with a rotary and a feed drive, the feed of the linkage is set as a function of the pressure of the drive fluid for the borehole motor in such a way that the liquid pressure remains in a predefined range or else remains constant. If the borehole motor is equipped with an eccentricity for directional boring, for example with an angled housing, then, in addition or else independently of the feed control, a directional deviations normally resulting from the linkage torsion can be compensated for by the eccentricity or the linkage being set to a corrected path angle. Thus, the eccentricity during directional boring is set to an angle of attack<BR> <F>  q   =   a   -   b  </F><BR>   a   being the path angle of the desired boring direction,<BR>   b   being the torsion compensation angle   q   the angle of attack of the linkage.

Title: Messenger vessels to indicate downhole conditions
Inventor: JENKINS CHARLES RODERICK
IPC: E21B47/12
Filed: 2002-12-14
Abstract: A plurality of messenger vessels 60 are programmed or imprinted with signal information and are then positioned releasably in a downhole location. When released, the vessels are entrained in the flow of production or drilling fluid and carried to the surface where their presence is detected and their signal interpreted. Typically, the signal comprises their original location in the well and a threshold value that a certain variable has exceeded. They may provide information about pressures, temperatures, compostions and levels of equipment wear or activity. The messenger vessels may be microdots or may contain radio frequency tags that are stimulated to emit induced radio fields by a combined radio emitter and detector 70. The vessels may be retrieved from oil-water separation apparatus 40. The downhole location may be on the wall of the borehole or casing, with the vessels held by release mechanisms 22, or on a downhole tool such as a perforator (figure 8).

Title: Randomized playback of tracks in a multimedia player
Inventor: SCHILLING JR WALTER W
IPC: G11B33/00
Filed: 2003-01-15
Abstract: An audio reproduction apparatus randomizes or shuffles the playback order of tracks from a prerecorded media such as a compact disc within a multiple-disc changer. Shuffle sequences are generated using a linear congruential random number generator (LCRNG). The shuffle sequence does not have to be stored since a next track in the sequence can always be generated from the LCRNG using a particular set of parameters. The parameters are determined in response to the number of track (or discs) in a sequence and include elements obtained from a lookup table and elements that are randomly selected so that the same sequence is not always generated for a certain sequence length.

Title: Method for the removal and recovery of oily components from drill cuttings with liquid carbon dioxide
Inventor: MASSETTI FELICIA
IPC: B01D11/02
Filed: 2003-12-18
Abstract: Method for the removal and recovery of oily components from drill cuttings comprises treating the drill cuttings with liquid CO2 in an extractor 3. The mixture of drilling cuttings and liquid CO2 form two components, a liquid phase (i.e. a solution of oil and liquid CO2) and a solid phase (cuttings). The solution leaves the extractor in a form of a CO2 solvent with oily fractions. The solution is then expanded and heated with a lamination valve 4 and a heat exchanger 5 respectively to become a vapour of CO2 and liquid oil. The oil is then separated from the CO2 vapour via a cyclone separator 6. The CO2 is then collected to be reprocessed and recycled into liquid CO2 by a condenser 8, and stored in an accumulation tank 1 to be used again.
