A pipe handling system (100) comprises a pipe rack (102) moveably coupled to a stationary frame (104). The pipe rack is configured to support a plurality of pipes between a loading end and a storage end. The pipe rack is moveable between a loading position where the loading end is positioned at a higher elevation than the storage end and an unloading position wherein the storage end is positioned at a higher elevation than the loading end. An arm (116) is rotatably coupled to the loading end of the rack and is configured to engage a single pipe and move the single pipe onto or off of the pipe rack.

A method and apparatus for transporting and assembling a drilling rig is disclosed. The drilling rig of a preferred embodiment of the present invention utilizes specialized positioning pads integral to the side boxes of the drilling rig to facilitate the connection of the center drill floor of the drilling rig to the side boxes of the rig. A preferred embodiment of the present invention may also utilize a specialized positioning dolly and an adjustable fifth-wheel truck connection for transporting the mast to the drill site, assembling the mast sections together, and positioning the mast for connection to the drill floor of the rig. The result is a unique drilling rig design and sequence for assembly that significantly reduces the time required to transport the rig from location to location and to assemble the rig at the drill site.

A packer retriever having a grapple body rotatably and slideably coupled to a mandrel directly attached to a milling tool can engage a packer (or extension thereof) having a substantially smooth I.D. in a wellbore while the packer is milled. The mandrel rotates in a central opening through the grapple body. The grapple body does not rotate when released from teeth of a nut on the mandrel and can remain engaged to the packer (or the extension) as milling proceeds. The mandrel includes a specially designed shoulder and the grapple body includes a specially designed bearing, both casehardened, which allow the mandrel to rotate constantly while reducing the effects of wear. The packer retriever remains in the engaged position to prevent the packer from falling if it breaks loose while milling. The packer retriever can transfer torque to the packer and can be engaged and released multiple times.

An elevator (10) comprises a body (12) having a longitudinal axis therethrough. The body (12) is operable to at least partially surround and support a tubular member (100) aligned with the longitudinal axis. The body (12) has a longitudinal opening (34) that is sized so as to allow the tubular member (100) to pass therethrough. A door (16) is rotatable about the longitudinal axis of the body (12) and has a closed position wherein the tubular member (100) is retained within the body (12) and an opened position wherein the tubular member (100) can pass through the longitudinal opening (34).

Methods and apparatus are disclosed for spooling a flexible member (14) onto a drum (12) with a spooler assembly (20). In certain embodiments, a spooler assembly (20) comprises a spooler arm (22) operable to guide a flexible member (14) onto a drum (12) rotating about a drum axis. A first actuator (23) moves the spooler arm (22) in a first direction that is parallel to the drum axis. The first actuator (23) operates in a first mode wherein the flexible member (14) is allowed to free movement in the first direction and a second mode wherein the first actuator controls the movement of the flexible member (14) in the first direction. The spooler assembly (20) may also comprise a second actuator (26) that moves the spooler arm (22) in a second direction that is perpendicular to the drum axis.

A magnetic circuit, a method of forming a magnetic circuit, a stator (10) or rotor (20) for an electric motor or generator, and an electric motor are disclosed. A magnetic circuit comprises a low reluctance magnetic flux path comprising a plurality of stacked metallic laminations (60,62) (each lamination having an edge (68,74)), and an air gap in operational relationship to at least a portion of the edges (68,74) of the stacked metallic laminations (60,62) (wherein magnetic flux flows at least partially through the stacked metallic laminations (60,62) and the air gap). Adjacent edges (60,62) of the stacked metallic laminations are intentionally offset (H L -H S ).
