Abstract: A method of monitoring the alignment of pipes to be welded end to end involves supporting a reference bar extending generally parallel to, and external of, the pipes so as to span a weld position of which the ends of two pipes are to be welded, performing measurements of perpendicular distance between the bar and each pipe at two predetermined distances from the end of each pipe, determining the thickness of the walls of the pipes, determining the slope of the exterior of each pipe with respect to the reference bar, calculating from the slopes the difference between the distances from the bar to the outer surface of each of the two pipes to the weld position, so as to provide a measure of the misalignment of the outer surface of the pipes at the weld position, differencing the wall thicknesses of the pipes to provide a wall thickness difference, and subtracting the wall thickness difference from the misalignment of the external walls of the pipe to determine the misalignment of the inner surfaces of the pipes

Abstract: A system and method for controlling the stopping point of a tufting machine in relation to a preset stitch pattern. The system includes a controller and an encoder to detect the current location of a tufting machine needle bar in the stitch pattern. Upon receipt of a stop signal, the controller insures that the needle bar is stopped at a preset stop step in the stitch pattern. In a preferred embodiment of the invention, the controller first slows the main drive shaft of the tufting machine to a jogging speed prior to stopping the tufting machine, and stops the machine at the home position of the carpet pattern. Introducing a delay between receipt of the stop signal and deceleration of the main drive shaft minimizes the jogging time of the machine. The method is directed to stopping the tufting machine at a predetermined stop step and at a position relative to degrees of mainshaft rotation.

Abstract: A high frequency shielded data transmission cable and method of making same are disclosed. Optimal transmission and minimal signal loss are achieved when the conductors of such a cable are maintained in fixed positions relative to one another and relative to the metal shielding. These features are provided by a cable of the instant invention wherein a central core having diametrically opposed spiral grooves hold the insulated conductors in fixed relation to one another. At least one inner layer of dielectric material maintains the insulated conductors within the grooves and provides a fixed spacing between the conductors and the metal shielding. Metal shielding, preferably of braided strips of metal, provides additional strength and flexibility to the cable. The interstitial spaces of the braid may optionally be filled with a filling compound. Likewise, the insulated conductors may be coated with a water-blocking compound to fill any spaces between the conductors and the walls of the grooves.

Abstract: A waterproof splice for use in connecting two multiconductor electric cables having jackets of different insulation material and a method of making the splice are disclosed. The splice consists of a mechanical electrical connection between the conductors, a mechanical bond formed on the insulation of one of the conductors and a sheath of insulation material molded over the splice and adjacent cables. The sheath bonds with the jacket of one cable and the mechanical bond formed on the insulation of the other cable. The mechanical bond is a seal ring of elastomeric material that is compressed between glands to move the seal ring into sealing engagement with the conductor. The disclosed splice is both strong and waterproof in spite of the poor bonding characteristics between the two different insulation materials on the two conductors. The splice is appropriate for cables having surface, subsurface and underwater applications and is specifically designed for use in conducting seismic surveying operations.

Abstract: An article, for example a pipe, has a first covering such as a polymer layer, and a second covering, such as a repair patch or a repair deposit of melt-on adhesive or a wrap or a sleeve protecting a welded joint between two lengths of such pipe. The second covering may have a functional coating on an underside which is applied on and is at least partially superimposed over the first covering. A cured deposit of thermoset resin is applied at least over the edges of the second covering, for example in the form of a fibrous tape impregnated with a curable resin composition, and bonds to the first and second coverings. The resin deposit provides the second covering with increased stability against displacement laterally of said first covering, for example as a result of soil stress.
