  • Patent number: 8347481
    Abstract: This invention provides an improved protective mat that includes a magnet at each end for temporally securing the mat to a pipe so that the mat remains in position during a welding process. The mat is flexible so as to conform to the curvature of the pipe and may be placed in any position preferable on the surface of the pipe. The positioned and secured mat prevents spatter from coming into contact with the external surface of the pipe lying under the positioned protective mat. The mat is preferably heat and fire resistant up to temperatures of about 1500° F. and may be a silicone-coated fiberglass mat. When the mat is not in use, the mat may be folded and the magnets may be used to secure the ends of the mat to one another.

  • Patent number: 8343022
    Abstract: A training apparatus for use by flyers in a cheerleading squad includes a stable base assembly, a balancing assembly, and a fixed or adjustable column located between the stable base assembly and the balancing assembly. The balancing assembly includes a deflectably resilient member and a standing surface that promotes proper alignment and mimics the feel that a flyer experiences when being supported by a base cheerleader. The deflectably resilient member provides two degrees of freedom of movement to the standing surface when the standing surface is under an external load. The standing surface preferably provides about the same standing area as that typically provided by a base cheerleader. The column may be a fluid-activated cylinder that moves between a first and second vertical position and simulates a flyer being raised by the base.

  • Patent number: 8319494
    Abstract: A pipeline inspection tool includes two pole magnets oriented at an oblique angle relative to the central longitudinal axis of the tool body. An array of sensor coil sets is located between opposing edges of the two pole magnets and oriented perpendicular to the central longitudinal axis. Each sensor coil set includes a transmitter coil and two opposing pairs of receiver coils that are gated to receive reflections from the wall of a tubular member. Because the line of sensor coils is rotated relative to the magnetic bias field, the receiver coils are in-line with, and have the same angular orientation as, the transmitter coil. The tool provides improved sensitivity to small defects, substantial decrease in RF pulser power requirements, full circumferential coverage, self-calibration of the transmitted signals, and less interference between transmitter coils caused by acoustic ring around.

  • Patent number: 8316500
    Abstract: A bidirectional bristle pig provides a means for collapsing or restraining the bristles so that the pig may be used in a reciprocating manner or, when the pig becomes stuck, the pig may be easily retrieved in a direction opposite that of the initial direction of travel. The bristle pig has at least one set of outwardly projecting cleaning wires or bristles located toward one end of the pig body and a sliding collar. The sliding collar moves between a first position and a second position to restrain the bristles at the desired leading end of the pig and forces the bristles downward and away from the inner wall surface of the pipeline. In the restrained state, the bristles no longer interfere with the movement of the pig in the desired direction. The sliding collar may move in response to pipeline pressure or may include a tether line.
