Abstract: A configurable clamp assembly for retaining pipe, conduit, cable bundles, waveguides and fiber optic cable that is designed for rapid installation without the need of pre-drilled holes or other mounting surface preparation. The clamp is formed by a saddle structure with integral rectangular flat base plate that receives interchangeable mounting pads and either a securing fastener or adhesive layer that secures the clamp to a mounting surface. A clamping yoke is hingedly secured to the saddle structure that is adapted to fold about the hinge to enclose and retain pipes, conduits or a Collar that engages an interchangeable Insert. The clamping yoke is fastened with a locknut that engages a threaded retaining post, locking the yoke to the saddle. The Insert is provided with various cross section geometries to secure waveguides, fiber optic cables and specially shaped tubing and is designed for insertion into the Collar for special applications.

Abstract: A technique is provided to control flow in subterranean applications, such as hydrocarbon fluid production applications. The technique utilizes an material formed, at least in part, of material that swell in the presence of a specific substance or substances. The material is deployed as a membrane outside a base pipe to desired subterranean locations. Once located, the material allows the flow of hydrocarbon fluids but swells upon contact with the specific substance or substances to limit inflow of undesirable fluids.

Abstract: An apparatus for use in a wellbore comprises a flow control device having an open position, a closed position, and at least one intermediate position. The apparatus further comprises a chamber and a movable member for actuating the flow control device, where the movable member is movable inside the chamber. The movable member causes a characteristic in the chamber to change in response to movement of the movable member to actuate the flow control device. A sensor detects the change in the characteristic inside the chamber that is indicative of actuation of the flow control device.

Abstract: The invention is a sealing system, such as a packer, that is used in a wellbore to seal against an exterior surface, such as a casing or open wellbore. The sealing system includes a swellable material that swells from an unexpanded state to an expanded state thereby creating a seal when the swellable material comes into contact with a triggering fluid.

The board exhibits properties of a metallic board so that the surface of the board can receive magnets. The board can also be printed by silk-screening or sublimation printed with inks to produce graphics which are permanently on the surface of the board and are not erased.

The downhole tools may comprise any hydraulically actuated tools, such as valves, packers, or perforating guns. Each tool is associated with an indexer, in one embodiment, so that the tools can be operated in concert and as a system.

Abstract: An on-edge stacking machine having a mailpiece input device to release mailpieces, one at a time, to a stacking deck for stacking. A speed monitoring device and a sensing device are used to monitor the moving speed and the arrival time of a mailpiece from the input device to a reference point of the stacking machine. Based on the moving speed and the arrival time, a displacement distance of the arriving mailpiece is computed. A segmented roller is then used to move the arriving mailpiece into the bottom of the stack in a two-part motion cycle, based on the displacement of the arriving mailpiece.

Abstract: Process of producing polytrimethylene terephthalate (PTT) by esterification of terephthalic acid (TPA) with trimethylene glycol (TMG) in the presence of a catalytic, titanium compound, precondensation and polycondensation. The esterification is effected in at least two stages, where in the first stage a molar ratio of TMG to TPA of 1.25 to 2.5, a content of titanium of 0 to 40 ppm, a temperature of 245 to 260° C. as well as a pressure of 1 to 3.5 bar are adjusted. In the at least one subsequent stage a content of titanium is adjusted which is higher than in the initial stage by 35 to 110 ppm. For generating the vacuum in the polycondensation and in the precondensation, there are used vapor jet pumps operated with TMG vapor.

Abstract: The present invention relates to a method for screening of polycondensation catalysts, wherein at least two polycondensation catalysis reactions are performed simultaneously under substantially equivalent conditions in at least two reaction cells which are present in one and the same room, using a sample comprising material to be polycondensated and a catalyst to be screened, and wherein the performances of the catalysts are analyzed.

Abstract: An improved process for the polymerization of polytrimethylene terephthalate by esterification of terephthalic acid or dimethylterephthalate with 1,3-propanediol (PDO), precondensation of the esterification product to produce a precondensation product, and polycondensation of the precondensation product to produce polytrimethylene terephthalate wherein excess PDO is removed from the esterification and/or polycondensation stages and PDO vapor is separated from the high boiling fraction (solid byproduct). The improvement comprises: (a) heating the solid byproduct in the presence of about 5 ppm to about 5000 ppm, based on metal, of a metal catalyst selected from the group consisting of one or more 3rd, 4th, or 5th row metal compounds from Groups 3-12 and Groups 14-15 of the Periodic Table (IUPAC 1989) at a temperature of from about 100° C. to about 240° C.

Abstract: This invention is an improvement upon the known process for polymerization of polytrimethylene terephthalate by esterification of terephthalic acid or dimethyl terephthalate with 1,3-propane diol, precondensation of the esterification product to produce a precondensation product, and polycondensation of the precondensation product to produce polytrimethylene terephthalate and, optionally, solid stating of this product to produce higher intrinsic viscosity polytrimethylene terephthalate.
