Publication number: 20160194915Abstract: A mud motor bearing assembly for use in drilling a hydrocarbon well. The bearing assembly includes a bearing section containing stationary bearing rigs and rotating bearing rings in stacked arrangement. The bearing rings have wedge-shaped projections. The wedge-shaped projections of two adjacent stationary bearing rings form a recess to accommodate the projection of a rotating bearing ring in sliding engagement. The bearing assembly is capable of bearing both radial and axial loads.Type: ApplicationFiled: January 8, 2016Publication date: July 7, 2016Applicant: Ashmin, LCInventors: Gunther HH von Gynz-Rekowski, William C. Herben, Daryl E. Bolejack

Patent number: 7882904Abstract: An apparatus for controlling the direction of drill bit within a wellbore. The apparatus comprises a first housing with a first housing axis therein, and wherein the first housing has a first threaded opening having a first threaded opening axis. The first housing has a helical end. A second housing is included, and the second housing contains a second housing axis, and a second threaded opening having a second threaded opening axis configured to engage with the first threaded opening. A collar is included that has a helical collar end that engages the helical collar end and wherein the helical collar end is configured reciprocal to the helical end, and rotational displacement of the first housing relative to the collar will angularly displace the drill bit axis. The apparatus may further include spline members for locking the collar in place relative to the first and second housing.Type: GrantFiled: December 20, 2007Date of Patent: February 8, 2011Assignee: Ashmin, LCInventors: Gunther H H von Gynz-Rekowski, William Christian Herben, Daryl Elliot Bolejack

Patent number: 7882638Abstract: A process for manufacturing a bearing. The bearing may be used in a tool disposed within a bore hole. The process comprises providing a tubular sleeve and applying a hard facing material on the outer diameter of the tubular sleeve so that the hard facing material is fused onto the outer diameter, and thereafter applying a material layer on the outer diameter so that the material layer is fused onto the outer diameter. The method further includes machining the outer diameter so that a portion of the material layer is removed, and then machining the inner diameter so that only the hard facing material is left as an inner diameter. The method further includes machining the outer diameter and the inner diameter in order to form the bearing. In the most preferred embodiment, the method further includes placing the bearing into a housing, and inserting a mandrel into the bearing, and wherein a hard coating of the mandrel abuts the bearing. A mud motor for rotating a bit in a well bore is also disclosed.Type: GrantFiled: June 21, 2005Date of Patent: February 8, 2011Assignee: Ashmin LCInventor: Gunther H H von Gynz-Rekowski

Patent number: 7434623Abstract: A percussion apparatus and method of using the percussion apparatus. The apparatus may be used for delivering an impact to a tubular string. The apparatus comprises a cylindrical member having an internal bore containing an anvil and a first guide profile. The apparatus further includes a rotor disposed within the internal bore, and wherein the rotor member comprises a body having an outer circumference with a second guide profile thereon, and wherein the rotor contains a radial hammer face. In a first position, the second external guide profile of the rotor will engage with the first guide profile of the cylindrical member so that the radial hammer face can contact the anvil. In a second position, the second guide profile of the rotor will engage with the first guide profile of the cylindrical member so that the radial hammer face is separated from the anvil shoulder. Multiple rotors and multiple stators may be employed. The rotor may be operatively associated with a stator that directs flow into the rotor.Type: GrantFiled: May 25, 2005Date of Patent: October 14, 2008Assignee: Ashmin, LCInventor: Gunther HH von Gynz-Rekowski

Patent number: 6966373Abstract: An inflatable sealing assembly integrated with a flow carrier which seals the inside of the flow carrier upon detection of a physical condition (e.g. fluid pressure). The inflatable sealing assembly includes a housing, a compartment in the interior of the housing for storing an inflatable sealing device, an inflating mechanism, and a sensor. Upon detection of the physical condition in the exterior and/or interior of the flow carrier, the sensor activates the inflating mechanism, preferably automatically, to inflate and deploy the inflatable sealing device which seals off the inside of the flow carrier. The inflatable sealing device may be an air bag.Type: GrantFiled: February 27, 2004Date of Patent: November 22, 2005Assignee: Ashmin LCInventor: Gunther Von Gynz-Rekowski
