Patent number: 11788363Abstract: A clamp assembly, for mounting around a tool joint coaxially joining cylindrical upper and lower workpieces, comprises an upper collar assembly and a lower collar assembly, each having semi-cylindrical left and right collar segments. The left and right collar segments of each collar assembly are removably connectable to each other by threaded fasteners to form the collar assembly. The upper and lower collar assemblies are coaxially mountable around the upper and lower workpieces, respectively, such that tightening the fasteners will urge the upper and lower collar assemblies to grip the upper and lower workpieces, respectively, and thus to provide increased resistance to relative rotation between the two workpieces about the tool joint axis. The upper and lower left collar segments, and/or the upper and lower right collar segments, may be interlockingly and radially slidable relative to each other to accommodate differences between the outside diameters of the two workpieces.Type: GrantFiled: April 5, 2021Date of Patent: October 17, 2023Assignee: Noetic Technologies Inc.Inventors: Maurice William Slack, Victor Yung

Patent number: 11560761Abstract: An axial linkage acting between the main body and the gripping assembly of a tool for gripping tubular workpieces includes a drive cam body that coaxially engages an intermediate cam body via a drive thread, with the intermediate cam body coaxially engaging a driven cam body via a driven thread, and with the drive thread and the driven thread having opposite orientations. The linkage includes a latch mechanism for preventing relative axial displacement of the drive cam body and the driven cam body. In operation while unlatched, the linkage converts bi-directional relative rotation into relative axial movement of the drive cam body and the driven cam body, thus increasing or decreasing the overall length of the linkage according to the rotational direction. The linkage can be re-latched using any of multiple operational sequences.Type: GrantFiled: October 26, 2021Date of Patent: January 24, 2023Assignee: Noetic Technologies Inc.Inventor: Maurice William Slack

Publication number: 20220259930Abstract: A rotary latch release mechanism includes axially-aligned upper and lower rotary latch components carried on and rotationally coupled to upper and lower latch assemblies, respectively. The latch release mechanism is movable from an axially-latched position to an axially-unlatched position in response to relative rotation between the upper and lower rotary latch components. The latch release mechanism has a movable land surface that acts in response to relative axial displacement to induce the relative rotation required to release the latch. The latch release mechanism may be configured such that the axial movement of the movable land surface will cause the relative axial movement required to release the latch in combination with the required rotation. Accordingly, the rotary latch mechanism operates in response to externally-controlled axial movement of a movable land surface carried by the latch release mechanism, without requiring externally-induced rotation.Type: ApplicationFiled: May 2, 2022Publication date: August 18, 2022Inventor: Maurice William SLACK

Patent number: 10787878Abstract: A tool for launching wiper plugs into a casing string in a gas or oil well during cementing operations employs a collet-like mechanism carrying radially-movable jaws arranged to retain a plug in a fluid flow path when the tool is in a closed position, and to release the plug into the fluid flow path when the tool is in an open position. Selection of the desired operational position of the plug launcher (i.e., open or closed) is effected by actuation of an axially-movable sliding sleeve. Alternative means for actuating the sliding sleeve include rotary actuation about the tool's longitudinal axis, rotary actuation about a radial axis generally normal to the longitudinal axis, rotary actuation about a generally tangent axis, and pneumatic or hydraulic actuation. The tool may be adapted to carry multiple wiper plugs for sequential launching into a casing string.Type: GrantFiled: March 31, 2017Date of Patent: September 29, 2020Assignee: Noetic Technologies Inc.Inventor: Maurice William Slack
