  • Patent number: 10203052
    Abstract: The invention relates to a flexible pipe carcass comprising a flexible tubular wall structure comprising a helically wound wall strip; wherein interlocking sections of successive windings of said wall strip form the wall structure. The interlocking sections of adjacent wall strips define a length and are movable with respect to each other between a first position and a second, extended position for changing said length, the interlocking sections being formed such that in the extended position a carcass gap is provided between adjacent interlocking sections for accommodating relative movement there between upon flexure of the wall structure. An insert profile is located in the carcass gap of the tubular wall structure on an inside of the wall structure to at least partly cover the carcass gap.

  • Patent number: 10202987
    Abstract: Embodiments of a directional valve assembly that provides a single device with functionality of a two-position design for automated operation and functionality of a three-position design for manual operation. The embodiments can include a housing with a piston chamber and a spool member that transits in the housing to regulate the flow of a working fluid to a cylinder. The embodiments can also have one or more pilot operators that regulate the flow of pilot air into the piston chamber to move the spool member between two positions, i.e., two open positions. The embodiments can also have a manual operator (e.g., a lever) that can move the spool to the open positions and to a closed position. In one embodiment, the spool member is configured to remain in either a first position, a second position, or a third position in the absence of an outside stimulus on the pilot operators.

  • Patent number: 10184594
    Abstract: A composite pipe and method of manufacture comprises an inner core coated with a resinous material, a prepreg material helically wound about the inner core and an outer shell covering the wound prepreg materials. The materials are applied at preselected melt temperatures to assure coherence among the materials and preclusion of voids and/or annuli therebetween. The melt temperature of the inner core is greater than the melt temperature of the coating and prepeg layers such that the heating needed to cohere these materials has no deleterious effect on the integrity of the inner pipe core. A cooling of the inner pipe core during initial application of the tape layer of prepreg materials stabilizes the radial configuration of the pipe core during tape wrapping and thus the appearance of undesirable voids and/or annuli in the composite pipe mass.

  • Patent number: 10157688
    Abstract: A device for isolating, accumulating, indicating and venting gas in a fluid system pipe includes a coupling affixed to a system pipe. The coupling includes an isolation valve. A standpipe is attached to the coupling. The standpipe holds a float trapped between a flow retaining orifice and a closed upper end save for an angled hole therein that allows gas to flow around the float. An indicator exterior to the pipe indicates the float's level in the standpipe regardless of system pressure changes. A vent valve attached above the standpipe allows controlled ventilation of the gas flowing from the system pipe through the standpipe and through the vent valve. Accumulation of gas from the system pipe lowers the float in the standpipe, at which point the user vents the gas, causing the float to rise with the rising fluid level.
