  • Patent number: 10408376
    Abstract: A tool designed for manipulation by an operator from a safe position out of line with the pig receiver opening in case an equipment failure or inadvertent opening of the trap before complete depressurization thereof should cause the pig to eject from the open end of the receiver. The tool features two main components, primarily a reaching assembly of substantially linear configuration having an elongated shape whose length runs along a first longitudinal axis, which lies generally parallel with a central longitudinal axis of the trap barrel during use of the tool, and support assembly that projects laterally from the reaching assembly in a direction generally perpendicular thereto so as to extend along a transverse axis that extends radially of the longitudinal axis.

The ROV operates a bucket drive (22) causing the connector to engage the blind hub in sealing fashion thus enclosing the magazine in a launch chamber (3). A hydraulic ram (11) indexes the magazine to select a chamber from which a pig is to be launched or an empty chamber to receive a pig. Indexing is achieved by a roller on the free end of the ram shaft engaging in a cusped track (26) on the magazine.

    Abstract: The present invention is a pipeline pig for cleaning the interior of a pipeline, the pipeline pig having a longitudinal pig body with forward and rearward elastomeric propulsion members affixed to and supporting the pig body substantially concentrically in a pipeline, the propulsion members functioning to move the pig body through a pipeline by the force of fluid flow and a plurality of spaced apart elastomeric diagonally oriented scrapers radially extending from the pig body, each scraper member having a semi-circular outer peripheral edge configured and dimensioned to engage the interior wall of a pipeline to thereby scrape and clean the interior pipeline wall as the pig is moved through the pipeline and provide additional support for the pig substantially concentrically in a pipeline. Orientation of the scraper enhances scraping effectiveness by slicing through any debris buildup, separating the debris from the inner pipe wall so that it can be pushed out of the pipeline by the pig discs or cups.

  • Patent number: 8636055
    Abstract: A controlled aperture ball drop includes a ball cartridge that is mounted to a frac head or a high pressure fluid conduit. The ball cartridge houses a ball rail having a bottom end that forms an aperture with an inner periphery of the ball cartridge through which frac balls of a frac ball stack supported by the ball rail are sequentially dropped from the frac ball stack as a size of the aperture is increased by an aperture controller operatively connected to the ball rail.

  • Publication number: 20140000046
    Abstract: This extractor is a simple-to-use tool that aids in removing a pipeline inspection gauge (“pig”) from a pipeline. A standard hitch ball (or other protuberance) is affixed to the pig providing an attachment point for the extractor. Upon arrival of the pig into a receiver, the extractor is inserted into the receiver and centered over the pig's hitch ball. When pushed onto the hitch ball, the extractor's pulling bars are forced apart and out in angled pulling bar slots. Once the extractor's pulling bars pass the midpoint of the hitch ball, extension springs provide tension to the ends of the pulling bars urging them to slide closer together in the angled pulling bar slots. The angled pulling bar slots ensure the pulling bars are at their narrowest point and securely attached to the hitch ball when the extractor is pulled from the receiver thereby permitting pig removal.

  • Patent number: 8601634
    Abstract: A pig launching and retrieval valve, which is adapted to be mounted within a pipeline for fluid flow control and for inserting and retrieving pig devices, such as round nosed cylinders, balls, scrapers and the like, for pipeline cleaning, for separation of fluids within the pipeline and for other pipeline inspection and servicing activities. The pig valve is of universal nature, having sub flanges for adaptation of special flange mounting and/or API standard flange mounting. The pig valve has a trunnion supported valve ball and pressure energized seat members that are enabled to shift laterally within respective seat recesses and thus establish self-centering with the valve ball.

  • Patent number: 8572883
    Abstract: A firearm cleaning device comprises a flexible cable and threaded coupling assembly, to which a plurality of components may be attached individually or in combination for optimal configuration based on cleaning need and firearm type. A spear-point piercing adapter may be threadably attached to a cable with a coupling portion fixed thereto. The piercing adapter includes a threaded shank with a sharp tip, on which a cleaning patch is speared and a jag is threadably attached thereto, thereby sandwiching the cleaning patch between a body of the piercing adapter and the jag. The cleaning device and various components and attachments can be packaged and sold as a single compact device, which provides mobility for field use, configurability for use with a wide range of firearm types, and cost savings due to fewer components and reduced packaging size.

  • Patent number: 8434549
    Abstract: A ball catcher for recovering balls from wellbore fluids containing sand during flow back operations. The ball catcher has a receiving chamber for receiving the wellbore fluids containing sand, a first flow outlet for discharging a portion of the wellbore fluids and sand contained therein, and a diverter for redirecting balls entrained within the wellbore fluids. The redirected balls and a balance of the wellbore fluids also containing sand are received in a ball-retaining chamber. A blocker fit to the ball-retaining chamber retains the recovered balls therein while the balance of the wellbore fluids and sand contained therein is discharged from a second flow outlet and directed to downstream equipment through an auxiliary flow line. The retaining chamber can be isolated allowing the balls to be removed from the ball catcher without disrupting the flow back operation.
