Patent number: 11492857Abstract: A torque device for guiding a first torque device member relative to a second torque device member includes the first and second torque device members. Each of the torque device members has an operational axis of rotation and three clamp bodies spaced about the operational axis. The clamp bodies are movable between a retracted passive position and an extended active position. The torque device also includes a guide ring on one of the torque device members. The guide ring includes one or more guide ring sections. In addition, the torque device includes at least two guide elements on the other of the torque device members. Each guide element being movable with one of the clamp bodies of the respective torque device member.Type: GrantFiled: December 13, 2019Date of Patent: November 8, 2022Assignee: NATIONAL OILWELL VARCO NORWAY ASInventors: Jonathan Garrick Webb, David Allen Hill, Trond Werner Moen

Patent number: 11059547Abstract: A system on a marine vessel or platform supports a load while allowing heave compensation. The load is supported via a hydraulic actuator. A transformer of the system includes a power source and at least one hydraulic pump/motor, for communicating energy between any two of: the hydraulic actuator; a hydraulic accumulator; and a power source. A valve associated with the pump/motor is switchable during at least one cycle of the pump/motor for selectively providing fluid communication between a drive chamber of the pump/motor and any of the hydraulic actuator, the hydraulic accumulator, and a hydraulic fluid reservoir, via at least one port of the drive chamber, so as to allow a desired displacement of hydraulic fluid from the pump/motor to be obtained.Type: GrantFiled: October 3, 2017Date of Patent: July 13, 2021Inventors: Kristjan Kristjansson, David Allen Hill, Slawomir Kukielka, Steinar Bø Nilsen

Publication number: 20210196112Abstract: A device which illuminates internal tissue and organs of a patient is described. The illumination member includes an array of light-emitting diodes (“LEDs”). The arrangement of the array depends on the configuration of the device and the procedure for which the device is being used. In all cases, the illumination member is used to illuminate relevant organs or structures in the body in order to increase visibility during surgical procedures. The LED array reduces the potential for inadvertent injury to internal structures for procedures located throughout the body. These procedures include those involving the reproductive organs of males and females, gastric and bariatrics, and other structures in the abdomen.Type: ApplicationFiled: March 12, 2021Publication date: July 1, 2021Inventors: David Allen Hill, Shawn Ramsey, William Roberts

Patent number: 10550651Abstract: An apparatus for applying torque about an operational axis of rotation includes a first torque device member. In addition, the apparatus includes an actuator support configured to move radially relative the operational axis and configured to be restricted from rotating in a plane oriented perpendicular to the operational axis. Further, the apparatus includes a first torque actuator pivotally coupled to the first torque device member and the actuator support. Still further, the apparatus includes a rod or a second torque actuator pivotally coupled to the first torque device member and the actuator support. Moreover, the apparatus includes a second torque device member coupled to the first torque device member and disposed about the operational axis of rotation. The actuator support is pivotally coupled to the second torque device member and is configured to pivot about a first pivot axis towards and away from the operational axis of rotation.Type: GrantFiled: September 5, 2012Date of Patent: February 4, 2020Assignee: NATIONAL OILWELL VARCO NORWAY ASInventors: Jonathan Garrick Webb, David Allen Hill, Trond Werner Moen
