Patent number: 10760340Abstract: An apparatus including a rotating segment having a first radial surface, a non-rotating segment having a second radial surface, a housing disposed around the first and second radial surfaces, and one or more rolling elements disposed between and in contact with the first and second radial surfaces for transferring the non-rotating segment in an axial direction upon rotation of the rotating segment. The non-rotating element may be a second rotating element that rotates at a different rotational rate than the rotating element. Each rolling element moves 360 degrees along a circular path relative to the first radial surface and the second radial surface. The first or second radial surface has a tapered section.Type: GrantFiled: March 13, 2018Date of Patent: September 1, 2020Assignee: Ashmin Holding LLCInventors: Gunther H H von Gynz-Rekowski, Michael V.

Patent number: 10408007Abstract: A downhole tool includes a valve assembly and a shock absorbing assembly. The valve assembly includes a valve spring operatively connected to a valve body. The shock absorbing assembly includes a spring operatively connected to a shock absorbing body having a fluid passage therethrough. The valve body is configured to selectively engage the shock absorbing body to create a fluid tight seal over the fluid passage in a first position, and to allow a fluid flow through the fluid passage in a second position. The repeated movement cycle of the selective engagement between the valve body and the shock absorbing body generates a pressure pulse or a varying pressure differential across the downhole tool. The repeated movement cycle is powered by a fluid flow. The tool may be selectively activated and deactivated.Type: GrantFiled: January 18, 2017Date of Patent: September 10, 2019Assignee: Rival Downhole Tools LCInventors: Gunther HH von Gynz-Rekowski, Russell Koenig, Michael V. Williams, Kevin J. Rudy

Publication number: 20190169935Abstract: A drilling machine for a wellbore is provided. The drilling machine may include one or more dynamic lateral pads (or simply “pads”) that are movable between an extended and retracted position. Generally, the pad(s) are deployed on the bend side of the drilling machine proximal to the drill bit and distal of the bend of the housing. While drilling, the drill bit may experience a deviation force that causes the drill bit to become misaligned with its original course. By extending the pad(s), however, the drilling machine can counteract the deviation force. Deployment of the pad(s) can produce a restorative force in opposition to the deviation force, thereby reducing or eliminating the directional tendency resulting from the deviation force.Type: ApplicationFiled: February 8, 2019Publication date: June 6, 2019Inventors: Edward Spatz, Michael Reese, Gregory Prevost, Michael V. Williams, Barry LaCoste, David P. Miess, William W. King
