Patent number: 11021321Abstract: A fluid coupling includes a body, a poppet valve assembly, a handle shaft assembly, and a retention member. The body has a fluid conduit, a through-hole extending through a sidewall, and one or more openings that extend between an external surface of the body and an interior of the through hole. The poppet valve assembly is disposed within the fluid conduit and is selectively movable between an open position and a closed position. The handle shaft assembly extends through the through-hole and into the fluid conduit and is interconnected with the poppet valve assembly such that the handle shaft assembly can be actuated to move the poppet valve assembly between the open position and the closed position. The retention member is insertable through the one or more openings and into the through-hole to interact with the handle shaft assembly to selectively hold the handle shaft assembly in the body.Type: GrantFiled: July 3, 2019Date of Patent: June 1, 2021Assignee: OPW-Engineered Systems, Inc.Inventors: Joseph P. Roth, David Morrow, Krzysztof Wejdman, Stephen Hudson, Shiang Taing

Patent number: 10571038Abstract: A breakaway coupling includes a body and a valve assembly inside the body. The body includes a fluid conduit and a shear groove between first and second portions. The shear groove is designed to crack, break, or separate under certain conditions. The valve assembly is designed to shut off fluid flow through the fluid conduit when the shear groove cracks, breaks, or separates. The valve assembly includes a valve seat, a sealing element, one or more pins, and a biasing member. The one or more pins hold the sealing element in an open position while the shear groove is in tack, and allow the sealing element to move to a closed position (with the help of the biasing member) in the event the shear groove cracks, breaks, or separates.Type: GrantFiled: July 17, 2018Date of Patent: February 25, 2020Assignees: OPW Engineered Systems, Inc., Operations Technology Development, NFPInventors: Joseph P Roth, Michael Crum, Dennis R.

Publication number: 20190187022Abstract: A system and method for determining a residual life of a swivel. The method includes determining at least one of an angular rotation, a linear displacement and a rotational direction of at least one swivel and determining rotational count of the at least one swivel based on the determined at least one of the angular rotation, the linear displacement and the rotational direction of the at least one swivel. Further, the method includes indicating a residual life information of the at least one swivel based on the determined rotational count of the at least one swivel. Further, the embodiments herein also provide an electronic device for determining residual life of a swivel.Type: ApplicationFiled: December 19, 2018Publication date: June 20, 2019Applicant: OPW- Engineered Systems, Inc.Inventors: Gautham RAMAMURTHY, Chandra Sekhar PANDA, Ishank Kumar RAWAT, Srishti TIWARI, Anvith Bannur GOPINATH, Phaneendra Govindasetty TIRUMANI, Don JOHNSON

Patent number: 9169949Abstract: Lock down units and loading arms with lock down units are disclosed. According to one embodiment, a loading arm includes a product delivery pipe pivotally coupled to a product standpipe such that the product delivery pipe is rotatable in a vertical plane. A rocker assembly is coupled to the product delivery pipe. A support arm may be pivotally connected to the product standpipe and slidably coupled to the rocker assembly such that the support arm and the rocker assembly are slidable with respect to one another. The support arm comprises a plurality of slots. A locking pawl is affixed to the rocker assembly and selectively engagable with the slots such that, when the locking pawl is engaged with a slot of the support arm, the locking pawl couples the support arm to the rocker assembly, thereby preventing the product delivery pipe from being raised in the vertical plane.Type: GrantFiled: August 23, 2013Date of Patent: October 27, 2015Assignee: OPW Engineered Systems, Inc.Inventors: Joseph P. Roth, Krzysztof Wejdman
