  • Patent number: 9784269
    Abstract: A hydraulic tool includes a stator and a rotor rotatably disposed within the stator. At least one of at least an inner portion of the stator and at least an outer portion of the rotor includes an insert comprising a hard material. A method of forming a hydraulic tool includes attaching at least one insert comprising a hard material to a surface of a stator or a surface of a rotor. A downhole motor or pump includes a stator and a rotor. The stator includes at least one insert comprising a hard material disposed over at least a portion of an interior surface thereof and a matrix material at least partially surrounding the at least one insert. The rotor includes at least one insert disposed over at least a portion of an exterior surface thereof and a matrix material at least partially surrounding the at least one insert.

  • Publication number: 20120067967
    Abstract: A fluid applicator includes, a tubular configured to transport a fluid therethrough, and a rotatable member in operable communication with the tubular such that fluid transported through the tubular is deposited at the rotatable member near a rotational center of the rotatable member. The rotatable member is configured to produce sufficient centrifugal forces on the fluid through rotation thereof to urge the fluid radially outwardly from the rotatable member to coat an inside of an earth formation borehole tool.

  • Patent number: 7893819
    Abstract: Disclosed is a method for avoiding a collision in a lane change maneuver of a vehicle to a target lane, where objects in a lateral rearward space of the vehicle are detected by an ambience monitoring device and measures are taken to influence the vehicle. The method is characterized in that graded measures are provided that depending on their stage, involve warning the driver and/or intervening into a steering system of the vehicle and/or influencing safety devices. The measures of a selected stage are initiated, with the stage being determined depending on a relative position of a detected object with regard to the vehicle and/or a relative speed between the vehicle and the detected object as well as depending on the fulfillment of a lane change condition. Also disclosed is a device that is well suited to implement the method.

  • Publication number: 20100006342
    Abstract: A method of making a drilling motor for use in a wellbore includes defining a profile for an inner surface of a stator; configuring at least one cutting element on a support to at least partially form the profile; translating the support through a bore of the stator such that the at least one cutting element engages the inner surface of the stator; and forming a helical passage using the at least one cutting element by causing relative rotation between the stator and the support.
