Title: Determination of the orientation of geological beds from stratigraphic data in deviated wells
Inventor: VICKERMAN KRISTOFFER WILLIAM
IPC: G01V1/50
Filed: 2002-04-25
Abstract: A method is presented to determine the probable orientation of a geological bed near a drilling during drilling of a wellbore. The method requires the obtaining of all possible orientations of the geological bed penetrated by the wellbore, and all possible bedding orientations that are parallel to a fold axis or a local structural trend of the geological bed. These orientations are then compared to arrive at no more than two choices for the true orientation of the geological bed. Stereonet presentations of these orientations may be employed where superimposing the stereonet presentations provides at most two points of intersection representing the poles for no more than two choices of the true orientation of the geological bed.

Title: System and method for management of commodity shipment data
Inventor: LUCKE ROBERT B
IPC: G06Q10/00
Filed: 2002-06-19
Abstract: A commodity shipment data management system includes a loader computer for storage of shipment data in a loader database. The system prompts the user to enter values for shipment data parameters, and prevents entry of invalid values. Data may also be entered remotely by wireless transmission. A GPS receiver collects loader location data and sends it to t he loader computer. An output device records shipment data on a portable data storage medium which accompanies the shipment and is read into a destination weighscale computer. The system minimizes manual entry and transfer of data, reducing the risk of human error in data entry, and enhancing the reliability of the data. The GPS data facilitates verification of the geographical source a nd chain of custody of the shipped commodity, and, combined with data gathered by loader function sensors, facilitates detection of errors and fraudulent activity in connection with commodity shipments.

Inventor: PAYANT OLIVIER
IPC: D07B1/16
Filed: 2002-07-12
Abstract: A plastic impregnated wire rope is provided with plastic bands between its core and its outer strands so as to prevent contact between the wires of the core and those of the outer strands during flexing of the rope. This produces a substantial increase in the life of the rope. The method for manufacturing such rope involves wrapping plastic bands on the core just prior to laying outer strands on the core and on top of the plastic bands. Thereafter, the so formed rope is impregnated with molten plastic, which is then allowed to solidify.

Title: A functional gene array in yeast
Inventor: SWINDLE JOHN
IPC: C12Q1/68
Filed: 2000-12-08
Abstract: This invention relates to functional gene arrays of yeast. Novel aspects include the individual yeast cells, methods for making the yeast and the arrays, the arrays and uses for the arrays. A diploid bearing special genetic properties has been constructed to facilitate cloning of heterologous genes capable of providing essential functions. A selection method, using this strain allows the identification of haploid yeast strains dependent for life on heterologous essential genes. The arrays of these strains comprise a library of unique members where each member is dependent for survival on the function of a gene complementing a different essential host gene which has been inactivated by the insertion of a dominant selectable marker. These arrays provide screening platforms for agents that specifically target the activity of these complementing genes.

IPC: G03F7/40
Filed: 2001-05-01
Abstract: Method of fabricating microstructures on a substrate. The method comprises providing a substrate layer (100) having a first surface with a resist layer (102). First selected regions of the resist layer are exposed to an environment (104) that renders the resist layer more or less soluble in a developer solution. The resist layer is then developed to expose selected regions of the substrate surface (106a). Second selected regions (110) of the resist layer are then exposed to an environment (108) that renders the resist layer more or less soluble in the developer solution by aligning exposure of the second selected regions to the first selected regions. The first selected regions of the substrate surface are etched (106b). Second selected regions of the resist layer are then developed to expose the second selected regions of the substrate surface (110a). The substrate layer is then etched and the resist removed to form a multi-depth substrate.

Abstract: A compact power circuit breaker (1) has a molded insulative casing (3) providing the structural support and electrical isolation for the pole mechanisms (11) mounted in cavities (9) in the casing and the operating mechanism (33) mounted to the front of the casing. A grounded barrier (17) between the pole mechanisms (11) and the operating mechanism (33) protects the operator actuating push bottons controlling the operating mechanism and accessible through a molded insulative cover. Preferably, the grounded barrier (17) is sandwiched between a rear section (5) of the molded casing containing the pole cavities and a forward section (7) to which the operating mechanism is secured. The grounded barrier (17) is connected to an electrically conductive pan (61) extending under the molded insulative casing which also houses electrically grounded linkages coupling the operating mechanism to the vacuum interrupters of the pole mechanisms. A vented air gap (65) between the rear section (5) of the molded insulative casing and the grounded barrier (17) minimizes erosion of the molded insulative casing in the event of an arc penetrating the casings to the grounded barrier.

Title: Detonating cord and methods of making and using the same
Inventor: WOODALL MARK E
IPC: C06C5/04
Filed: 2001-05-23
Abstract: The velocity of detonation of an explosive such as detonating cord (18, 22) is controlled by the addition of a diluent to the explosive, e.g., to the core of the detonating cord (18, 22). An explosively inert diluent, or a diluent comprised of an explosive of lower brisance than the principal explosive comprising the core of the detonating cord, will serve to reduce the velocity of detonation. Such reduced velocity of detonation. Such reduced velocity of detonation has beneficial effects in certain operations, including cleaving rock (10), wherein it is observed to significantly reduce radial cracks (24) and stickers (26) (long radial cracks) in the vicinity of the boreholes (12) in which the low-velocity detonating cord (18, 22) is functioned to cleave the rock (10). The low-velocity detonating cord also facilitates leaving behind a smoother face in cutting trenches and tunnels through rock. The method of manufacture of low-velocity detonating cord includes incorporating a suitable diluent, such as phenolic microballoons, into an explosive core of, e.g. PETN.
