Publication number: 20030106716Abstract: A drive head for supporting a soil sampling tube in a drive assembly in which the head and tube are driven into the ground by a power source connected to the head or to at least one drive rod connected to the head. The drive head has a body portion in the configuration of a truncated cones, which is provided with an integral upper threaded nipple for attaching to the drive rod, and an integral lower threaded nipple for attaching to the sampling tube. The drive head has, in addition, a solid body provided with a venting passageway that extends from the lower threaded nipple to an outer surface of the truncated cone for venting air from the head and tube when the head and tube are driven into the ground.Type: ApplicationFiled: December 10, 2001Publication date: June 12, 2003Inventor: Robert J.

Publication number: 20030106717Abstract: A wellbore assembly is provided that is operable in wellbores in the range of six to six and one-half inches for obtaining large diameter cores, e.g., cores greater than or equal to two and seven-eighths inches in diameter. The wellbore assembly may preferably be utilized with drill pipe so that standard drilling rigs may be utilized in drilling and coring operations therewith. The drill pipe in accord with the present invention may be formed by modifying standard API drill pipe such as API four and one-half inch IF (Internal Flush) drill pipe in a special manner that renders the drill pipe still suitable for the type of drilling operations of interest and also suitable for handling by any drilling rig capable of using standard API drill pipe. Alternatively, the drill piper may be initially manufactured in accord with the specifications of the present invention.Type: ApplicationFiled: March 5, 2002Publication date: June 12, 2003Inventor: Douglas Kinsella

Publication number: 20030106719Abstract: The present invention comprises a centraliser (10) for mounting on a tubular member such as a section of casing, together with one or more stops (42, 48) for retaining the centraliser thereon. The stops (42, 48) are provided with profiles for engaging the centraliser to restrict rotation thereof. The centraliser (10) may be selectively permitted or restricted from rotation by selection of appropriate stops, and by relative movement of the stops and centraliser on the tubular. Certain embodiments of the centraliser (10) may also include blades (14) on the body thereof, the blades being formed such that the velocity and kinetic energy of fluid flow across the blades is altered, so reducing settling of drill cuttings within the bore and on the centraliser.Type: ApplicationFiled: December 20, 2002Publication date: June 12, 2003Inventor: Derek Frederick Herrera

Publication number: 20030106720Abstract: A raise boring head includes a roller cutter body and a saddle intended for rotary drilling in earth and rock formations. The roller cutter body is rotatably journalled on a shaft that is provided with two shaft spigots at its opposite ends. Each spigot has a second support surface provided for cooperation with a first support surface of the saddle to hold the roller cutter to the saddle. Each shaft spigot is provided with a hole for receiving a fastener that also passes through the second support surface in order to connect the shaft spigot to the saddle. The first support surface and the second support surface are curved. The first support surface and the second support surface connect directly or indirectly to stop shoulders for counteracting rotation of the shaft. The fastener is eccentric to the shaft axis and arranged to press the stop surfaces together.Type: ApplicationFiled: December 10, 2002Publication date: June 12, 2003Inventor: Stig-Ake Brolund

Publication number: 20030106721Abstract: A method for optimizing drilling performance of a roller cone drill bit is disclosed. The method includes simulating drilling with the bit in a selected earth formation to determine at least one drilling performance parameter. The orientation of at least one non-axisymmetric cutting element on the bit is adjusted and the simulating the drilling and determining the at least one performance parameter are repeated. The adjusting and simulating the drilling are repeated until the at least one performance parameter is determined to be at an optimum value. In one embodiment, the performance parameter includes rate of penetration.Type: ApplicationFiled: January 28, 2003Publication date: June 12, 2003Inventors: Amardeep Singh, Sujian Huang, Scott McDonough

Publication number: 20030106722Abstract: An apparatus for precisely weighing and bagging solid particulate materials in which a carousel is mounted on a vertical axis intermediate a material dispenser and a weighing device such as a load cell. A series of sheet metal material collectors, pivotally mounted on the carousel to receive material dispensed thereto, are indexed around to a series of dispensers and then to a bagging station where they are tilted to discharge material thereon.Type: ApplicationFiled: December 10, 2001Publication date: June 12, 2003Inventor: James H.

Publication number: 20030106723Abstract: Automotive load cells having centralized, multi-axis, loose tolerance overload/limit stops provide improved strain gauge response. The modular, integrated stop assemblies magnify sensor substrate deflection by use of opposed concave (Belleville) springs are used in direct contact with the substrate to accommodate ±Z axis deflection and Mx/My moment angular rotation. A flanged guide member on the load stud permits a wide range of geometries. The substrate is thickened around the load stud hole and the outboard support bolt holes. Hollow rivets assist in design modularity. Strain gauges are placed at the yield zones symmetrically with respect to the X axis. The substrate hole Mx/My gap is larger than the stop bracket hole to insure a positive stop for Mx/My moments prior to yield. The inventive multi-axis stop assembly is used in any type load cell, including rectangular, thinned, notched, necked/dogbone, or cantilever substrates with any strain gauge layout configuration.Type: ApplicationFiled: December 6, 2002Publication date: June 12, 2003Inventors: Rajeev Thakur, Alexander Golshteyn, Russ Watts, Darren Lee, Rajesh Das

Publication number: 20030106724Abstract: A coordinate input apparatus for inputting coordinate values through operations of a tablet attached thereto. The tablet is positioned in an overlaid fashion onto a body of the apparatus for coordinate value processing so as to permit input of the coordinate values through the tablet. On the other hand, the tablet is positioned in a manner not overlaid onto the body to render the apparatus body operable.Type: ApplicationFiled: July 22, 1999Publication date: June 12, 2003Inventors: SATOSHI MASAMITSU, FUJIO NOGUCHI

Publication number: 20030106725Abstract: A vehicle comprises a steering operation device, a pair of running-driving wheels, which differentially drive when the steering operation device is manipulated, a pair of steerable running wheels interlocking with the steering operation device, and a steering mechanism interposed between the steering operation device and the pair of running-driving wheels. The steering mechanism includes a pair of drive gears interlocking with the steering operation device and a pair of follower gears interlocking with the respective steerable running wheels. The drive gears mesh with the respective follower gears so as to control lateral turning of the respective steerable running wheels. A gear radius of the drive gear may be greater than that of the follower gear meshing with it. A gear ratio between the mutually meshing drive and follower gears may be variable.Type: ApplicationFiled: September 24, 2002Publication date: June 12, 2003Inventor: Koji Irikura
