Title: Logging tool with valve means to protect the tool from damage
Inventor: SPENCER MICHAEL CHARLES
IPC: E21B47/01
Filed: 2000-10-27
Abstract: A self-contained logging tool for a drill pipe comprises electronic apparatus for logging a well and a normally open fluid valve, 242, 2404, 2414, 2416. The valve is operable by differential movement of the drill pipe, e.g when the pipe meets an obstruction, such that fluid flow in the pipe is gradually restricted, thereby creating back pressure in the fluid. The back pressure provides an indication at the surface that the logging tool is stuck. A poppet valve 2422 may also be used. A valve is also disclosed which has an outlet which comprises first and second overlapping slot means, [241, 243, fig 7]. The first overlapping slot means is operated by pressure to move relative to the second overlapping slot means to progressively restrict fluid flow through the valve. The valve means may form part of a compression/tension device attached to the drill pipe.

Title: Vector recomposition of seismic 3D converted-wave data
Inventor: THOMSEN LEON A
IPC: G01V1/28
Filed: 2000-11-10
Abstract: This method of seismic processing of multicomponent converted wave 2-D and 3-D seismic data is useful where the seismic traces in each CCP gather may have been acquired at a variety of different source-receiver azimuths and especially useful in 3-D surveys and in 2-D crooked line surveys.. One embodiment provides a method of using recorded multicomponent seismic data to determine an estimate of the orientation of the two principle coordinate axes of a subsurface medium, with this determination potentially being made in each seismic survey bin, and for each depth. Given this estimate, the seismic data may then be transformed via rotation into the coordinate system so defined, and processed using conventional algorithms (e.g., to produce velocity functions and images). Another embodiment uses a given principle coordinate axis orientation to calculate a "best" data reduction of the traces in the CCP. The invention additionally solves the problem of deducing the principal times series and provides a means of combining multi-azimuth multi-component CCP gathers for further conventional scalar processing.

Patent GB-2375276-A (GB)
Title: Method and system of sound processing
Inventor: PEARCE DAVID JOHN BENJAMIN
IPC: H04R3/00
Filed: 2001-05-03
Abstract: A device 410 such as a mobile phone utilises a directional microphone array to discriminate voice signals from background noises. In order to do this, the location of a sound source relative to the array 412 must be known 402. The location of the source may be determined from signals produced in the microphone array but if the array is moved during a period of silence, it may take a long time for the source location to be reestablished. In order to mitigate this, a platform motion sensor 400 which may include a gyroscope and/or an accelerometer is attached to the microphone array. The location of the sound source may be estimated in a source location estimator 406 on the basis of the sound signal from the microphone array, and signals from the motion sensor. Results of the estimation are used by a sound enhancing processor for enhancing signal quality. The enhanced sound and source location estimate may be passed to a speech recognition module.

Title: Method and apparatus for minimizing loader frame stress
Inventor: FRANCIS JOHN E
IPC: E02F3/43
Filed: 2001-06-18
Abstract: A method and apparatus minimizes the loader frame stress induced by the twisting action which results from unequal travel in the actuators (224, 234). The method includes the use of electro- hydraulics in conjunction with feedback from actuators displacement sensors (226, 236). Each actuator (224, 234) is controlled by an individual control valve (220, 230). The amount of extension of each actuator's piston (225, 235) is monitored. Control signals are sent to the control valves (220, 16 230) which control fluid flow to each actuator (224, 17 234) to maintain the actuators' piston extensions at 18 the same amount or to stop the movement if the difference is more than a maximum amount. Also disclosed is an alternative arrangement where strain gauges on the frame detect twisting of the frame in place of the sensors (226, 236) detecting displacement of the actuators.

Title: API for access to content via metadata
Inventor: WILLIAMS MICHAEL JOHN
IPC: G11B27/031
Filed: 2002-03-25
Abstract: An application programmer's interface provides a facility for accessing metadata describing the content or attributes of information material. The application programmer's interface comprises a signalling protocol processor operable to receive a metadata string which includes a resource identifier providing an address of a metadata resource, and a file transfer processor operable to provide access to the metadata resource in accordance with a request from the application program. The signalling protocol processor provides an efficient facility for communicating the metadata string. The metadata string may be in the form of a mark-up language such as XML. The metadata resource may be for example a proxy version of the information material, such as a video proxy if the information material is video. Accordingly, the file transfer processor is arranged to provide efficient access to the video proxy using the address provided with metadata string. The address may be a Uniform Resource Identifier address allowing access to the resource from any network linked via the World Wide Web. The application programmer's interface therefore provides a standard interface format for making metadata and metadata resources available to application programs.

Title: CMOS vertical replacement gate (VRG) transistors
Inventor: CHITTIPEDDI SAILESH
IPC: H01L29/78
Filed: 2002-08-30
Abstract: An architecture and process for forming CMOS vertical replacement gate transistors is disclosed. An integrated circuit structure includes a major surface with first (120) and second (114) doped regions separated by an isolation region (140) which may be of silicon dioxide. Layers are deposited over these regions with trenches (200,202, Fig. 24) formed therein. Doped regions of the opposite conductivity from the respective first (120) and second (114) doped regions are formed in the trenches to form the channels of MOSFETs, with oxide layers (226,227) separating the channels from gates (240,242), which may be of polysilicon. The structure may also include doped regions (250,252) lying directly above first (120) and second (114) doped regions, having the same conductivity type as their respective region below and acting as source/drain regions in the MOSFET. These regions may be formed by diffusion of dopants from doped layers (142,144,160,164) in proximity to these regions. A method of forming the structure is also disclosed, where a sacrificial layer (152, Fig. 29) is removed before forming the gates (240,242), and boron and phosphorous-doped TEOS layers (142,146, Fig.18) are used in forming doped regions.

Title: The operation of a percussive drive of an earth drilling apparatus
Inventor: PUETTMANN FRANZ-JOSEF
IPC: E21B4/14
Filed: 2002-09-16
Abstract: A pressure medium feed 70 is connected or disconnected to a percussive piston 20 of an earth drilling unit when the pulling or thrusting drive transmitted to the drilling unit by a drill string exceeds or falls below a specific pull or thrust. The means for connecting or disconnecting the pressure medium feed 70 is provided in the form of a pressure tube 30 inside a housing 1 of the drilling unit, where the pressure tube 30 has a valve/hole 40 for connecting the pressure source to a pressure chamber 25 of the percussion piston 20. If the thrust drive falls below a specific thrust value, a spring 80 is decompressed and the pressure tube 30 is axially displaced. This allows the valve/hole 40 to be closed, thus disconnecting the pressure chamber 25 from the pressure tube 30 to stop the pressure being supplied to the percussive piston 20.
