    摘要: A drill bit and method of drilling a wellbore. The drill bit includes a pad configured to extend and retract from a surface of the drill bit, and a force application device configured to extend and retract the pad. The force application device includes a screw driven by an electric motor that linearly moves a drive unit to extend and retract the pad from the drill bit surface. The drill bit may be conveyed by a drill string and the pad may be extended from the drill bit face to drill the wellbore.

    摘要: A traction system for a vehicle has a support frame that defines a circular track belt support that is revolvable about an axis at its center, a flexible track belt; and a track belt stretching assembly comprising one or more track belt stretching rollers. The system has one traction configuration in which the flexible traction belt is held on said support track forming a substantially circular, wheel-like traction surface, and can change to a stretching state in which said rollers engage said belt and stretch it from its state in said one traction configuration to a stretched state to define one or more other traction configurations of the system.

    摘要: A bridge plug assembly that can be set in a wellbore tubular using wellbore pressure to form a pressure differential on a piston that actuates sliding members. A resilient member, such as a spring, is compressed from a downhole pressure differential. The bridge plug assembly can be removed by equalizing pressure across the piston and the spring. The spring can expand and re-stow the expanded plug. The plug can be formed from a nickel titanium alloy flexible member that can be selectively radially expanded so its outer surface sealingly engages a surrounding tubular. The percentage of weight of nickel can range up to about 40 to about 58%, 55% or to about 60%.
