摘要： A device for sealing and anchoring within a tubular member. The device comprises a top swage member disposed within the tubular member, with the top swage member having a longitudinal center of axis. Also included is a first sealing member disposed about the top swage member, with the first sealing member containing a first plurality of circumferential ribs disposed about the first sealing member. The device may also include a second sealing member that is attached to the first sealing member, with the second sealing member containing a second plurality of circumferential ribs disposed about the second sealing member. A bottom swage member is disposed within the second sealing member, with the bottom swage member having a longitudinal center of axis. The device further comprises a setting apparatus for driving the top swage longitudinally downward relative to the top swage's longitudinal center axis and for driving the bottom swage longitudinally upward relative to the bottom swage's center axis. In the preferred embodiment, the top swage member has a first cylindrical surface that extends to a second conical surface, and wherein the first cylindrical surface is disposed within the first sealing member. Additionally, the bottom swage member will have a first cylindrical surface that extends to a second conical surface, with the first cylindrical surface being disposed within the second sealing member. A method of anchoring and sealing a device within a tubular member is also included.

摘要： An apparatus for retrieving metal objects. The apparatus includes a housing with an inner part, with the housing having a first wall. The apparatus further includes a sleeve disposed within the housing, with the sleeve being constructed of a non-magnetic conduction material. A magnet is disposed within the sleeve, with the magnet having a north pole and a south pole. The apparatus further includes a container disposed within the sleeve, the container having a second wall. In the most preferred embodiment, the first wall defines a first pathway for magnetic lines of flux for the north pole of the magnet and wherein the second wall defines a second pathway for magnetic lines of flux for the south pole of the magnet so that a toroidal magnetic field is formed about the distal end of the sleeve. A method of retrieving a metal object within a well bore is also disclosed.
