  • Publication number: 20030089400
    Abstract: A spool for carrying continuous pipe or coiled tubing for a coiled tubing injector is dropped into a stand at a site and coupled to a rotary power source. The stand includes two axles, on either side of the spool, and a drive coupling. A pipe slideably extends through one of the axles. It is retracted when the spool is lowered onto the stand and then extended for communicating fluid between the coiled tubing and a fluid source. A swivel joint is connected to one end of the pipe. The pipe is permitted to turn with the spool or is held stationary with respect to the stand depending on whether the swivel joint is mounted outside the stand or inside the spool.

    Abstract: A backflow prevention apparatus has a valve body with a longitudinal axis that defines a flow path therethrough, and two end segments located at opposite ends of the valve body. Two check valve assemblies reside in series within the valve body. The valve body and end segments are connected to a pivot member that carries the valve body and allows it to swing in and out of axial alignment with the end segments. The check valve assemblies can be accessed and removed from the valve body when the valve body is pivotally moved out of axial alignment with the end segments.

  • Publication number: 20030089404
    Abstract: A check valve having a faceplate and an insert assembly. The faceplate and insert assembly have a stepwise cross-section in the direction of a forward fluid flow through the check valve. The stepwise cross-section is designed for placement of the faceplate and insert into a complementary shaped valve body. The faceplate defines at least two sections through which the fluid flowing through the check valve flows. The moving parts of the check valve, doors and hinges, are mounted on the insert such that the parts are not impacted by the fluid flow, thereby reducing maintenance on the check valve. Maintenance on the check valve can be accomplished by simply removing the faceplate, thereby releasing the insert assembly from the valve body so that the insert assembly can be replaced with minimum downtime to a cooling system having this check valve installed.

  • Publication number: 20030089408
    Abstract: A valve with an integral means for bleeding internal pressure prior to separation of a bonnet for the valve from its engagement with the valve body, provided by a bore through the valve body. This allows the internal pressure of the valve to equalize with atmospheric pressure prior to complete disassembly of the bonnet from the valve body. The bore through the valve body also serves as a leak detector, by providing a path for fluids passing through the valve to leak to the exterior of the valve body in the event of a failure of the seal between the bonnet and the valve body, which can readily be detected by passersby upon inspection of the exposed end of the bore at the exterior of the valve body.

    Abstract: Vacuum carburizing of ferrous workpieces is performed at low pressure in a vacuum furnace using a napthene hydrocarbon as the carburizing medium. The furnace is constructed to be generally transparent to the napthene so that cracking tends to occur at the workpiece which functions as a catalyst to minimize carbon deposits. The napthene is supplied in liquid form to fuel injectors which inject the liquid napthene as a vapor at duty cycles and firing orders to produce a uniform dispersion of the hydrocarbon gas about the work resulting in uniform carburizing of the workpieces. An in-situ methane infrared sensor controls the process. Hydrogen is added to the napthene to either assure full carbon potential and produce methane or to perform variable carburizing.

The textured-metastable grain structure is stable during sputtering of the sputter target. The textured-metastable grain structure has a grain size of less than 5 &mgr;m. The method forms aluminum alloy sputter targets by first cooling an aluminum alloy target blank to a temperature of less than −50 ° C. Then deforming the cooled aluminum alloy target blank introduces plastic strain into the target blank and reduces the grain size of the grains to form a textured-metastable grain structure. Finally, finishing the aluminum alloy target blank forms a finished sputter target that maintains the textured-metastable grain structure of the finished sputter target.

  • Publication number: 20030089437
    Abstract: The present invention provides a portable traction enhancement device. The present invention uses a section of conventional mesh screen material consisting of a directional weave of fiber material. The mesh material is installed in operable relation to a surface requiring enhanced traction such as a shoe sole or tire tread. Pressure exerted against the mesh causes localized melting in the icy surface allowing the strands of the mesh to engage the surface and enhance the tractional stability of the user.

  • Publication number: 20030089438
    Abstract: The invention relates to a pneumatic rubber tire with an outer, circumferential tread wherein said tread has a tread configuration comprised of spaced apart, raised lugs designed to be shock absorbingly ground contacting, wherein said tread and lugs are comprised of rubber selected from butyl rubber, halobutyl rubber or isobutylene-derived rubber. Said tire may also contain sidewalls comprised of one or more of such rubber. Thus, such tread is a combination of specific structural configuration and specific rubber composition to create a shock absorbing effect.

  • Publication number: 20030089439
    Abstract: A tread for a tire having a preferred direction of travel has a plurality of tread pattern blocks, the upper faces of which are intended to come into contact with the roadway during travel of the tire. The tread pattern blocks are provided with a plurality of wells of section S and of depth H, each block being divided into a front section and a rear section by a median plane Pv perpendicular to the upper contact face of the block and to the longitudinal direction of the tread and passing through the center of mass G of the contact face of the block when new. The front section has a leading edge and the rear section has a trailing edge. This tread is characterized in that, when new and for each tread pattern block which is provided with wells, the volume of all the wells located in the front section of the block is greater than the volume of all the wells located in the rear section of the block.

  • Publication number: 20030089441
    Abstract: The invention relates to a bracing ply comprising reinforcing elements, which are made of steel cords, for a vehicle pneumatic tire, in particular, for a pneumatic tire used on transporters or light trucks and reinforced pneumatic tires. Said bracing ply is provided with two steel cord plies (bracing plies) which are stacked in a radial direction, whereby the radially inner steel cord ply is wider in the axial direction of the tire than the radially outer steel cord ply. In addition, the individual steel cords of a ply run diagonally with a slope ranging from 18° to 25° with regard to the zenithal plane of the tire. The radially inner and the radially outer steel cord plies have opposed slopes, are comprised of individual filaments with a filament diameter of 0.32 mm, and are provided with a U+T structure (untwisted+twisted), whereby the radial distance between steel cord plies is smaller in the zenithal plane of the tire than in the shoulder areas.

    Abstract: A softer absorbent garment is prepared by incorporating elastic strands that are coated around their periphery. The elastic strands are coated with adhesive by immersing them in an adhesive-filled applicator comb prior to applying the elastic strands to the garment. The absorbent garment thus requires less adhesive, and the manufacturing method provides a cleaner work environment.

  • Publication number: 20030089449
    Abstract: A method of applying a protective strip to an edge of a wood product piece. The process uses a set of aligned rollers and a belt apparatus that includes a pair of rollers having a shoe positioned between them and a belt fitted about the rollers and the shoe. The distance from the belt to the first set of aligned rollers is substantially equal to the width of the wood product piece. The wood product piece is placed between the first set of aligned rollers and the belt apparatus and resin is applied to the edge the wood product piece. The wood products piece is then squeezed between the first set of aligned rollers and the belt apparatus. At least a subset of the rollers are driven to move the wood products piece along the belt apparatus, thereby causing the resin to be squeezed into the edge of the wood products piece. Finally, the resin is cured.
