    摘要： A core biopsy device comprises an outer cutting cannula in telescoping register with an inner spoon cannula. The outer cutting cannula is provided at a distal end with an arcuate excising blade that is biased radially inwardly to extend beyond the longitudinal axis of the cannula. The inner spoon cannula terminates at a distal end in an arcuate wall to form a biopsy sample spoon for supporting a biopsy sample thereon. The outer cutting cannula can be rotated relative to the inner spoon cannula so that the excising blade can excise the biopsy sample from the surrounding tissue. After removal of the core biopsy device from the tissue, the outer cutting cannula can be retracted away from the inner spoon cannula to reveal the biopsy sample and enable the sample to be removed from the biopsy device in a relatively undisturbed condition.

    摘要： An apparatus includes a housing configured to be disposed in a borehole in a resource bearing formation, the housing including an axially extending fluid conduit configured to receive borehole fluid, and a seating assembly including a convertible component that is configured to be actuated to move the convertible component in a radial direction between an open position and a seating position. The convertible component extends radially into the fluid conduit and forms a landing seat for an object when in the seating position, and the convertible component allows passage of the object therethrough when in the open position.

    摘要： An apparatus for determining a location of a downhole component includes at least one transmitter device and a receiver device. One of the at least one transmitter device and the receiver device is disposed at a first component of a borehole string configured to be deployed in a borehole and retained at a stationary position, and another of the at least one transmitter device and the receiver device is disposed at a moveable component configured to be moved while the first component is at the stationary position, the at least one transmitter device configured to emit a wireless signal and the receiver device configured to detect the wireless signal when the first component is at the stationary position. The apparatus also includes a processing device configured to receive signal data and estimate a location of the moveable component relative to the first component based on the signal data.

    摘要： A propulsion engine for an aircraft comprises an enclosure having a longitudinal axis oriented in a direction of travel of an aircraft, the enclosure including a series of walls and a plurality of ducts arranged along the longitudinal axis. Each of the ducts including a number of walls that are either dynamic or static in movement. Each of the ducts includes a central axis that is angled at, or can be adjusted to, an angle toward the front wall of the enclosure such that a top end of each duct is toward the front wall of the enclosure. A fan is disposed in each of the ducts configured to generate airflow along the respective central axes from the top end to the bottom end to provide lift and thrust to the aircraft.
