Abstract: A device for forming a union of pipe end includes two pipe connectors, each configured for attachment to an end of a length of pipe at one end and for joining to the other of the two connectors at the other end and a nut having a bore with internal threads configured to mate with outer threads on the outer surface of one or both of the two pipe connectors. The outer lateral surface of the nut includes a plurality of handle connection structures. The device includes a handle for increasing the amount of manually-generated torque on the nut during tightening or loosening of the nut with respect to the outer threads. The handle has a nut attachment end configured to engage the handle connection structures and is provided with a mechanism for reversibly locking the handle to any of the plurality of handle connection structures of the nut.

Abstract: An enclosure device for protection of drilling rig service utilities. The device includes a frame substantially covered by a plurality of removable or hinged panels to provide access to one or more racks for receiving and holding one or more arrays of conduits. The frame is configured to support one or more removable and reconfigurable racks for supporting the arrays of conduits within the enclosure with ends of the conduits extending outside of the enclosure device.

Abstract: The invention relates to a tool for applying torque to a hammer union having a hammer union wing with wing nuts. The tool comprises a wrench having an arcuate or circular shaped wrench head that can be placed around the hammer union wing, the wrench head having wing nut cavities in the inner surface for receiving the hammer union wing nuts, and sockets around the outer surface for receiving one or more lever members such as a torque bar and/or hammer lug for applying torque to rotate the wrench head. The lever member(s) may be positioned in any of the sockets in the wrench head, thereby allowing the lever member(s) to be repositioned during use with respect to the wrench head without having to remove the wrench head from the hammer union. The wrench head may be held in place on the hammer union wing using magnets.

Abstract: A torque restraint device for connection to a top drive or to a travelling block of a drilling rig. The device is reversibly connectable to a guide track connected to a mast of the drilling rig. The device includes a main body supporting a pair of lockable jaws connected with a hinge body. The jaws are configured to form a closed and locked bracket for engaging the guide track and configured to pivot on the hinge body to provide an open bracket to facilitate disengagement of the device from the guide track. The hinge body forms a connection between at least one of the jaws and the main body.

Abstract: An integral vacuum cleaner bumper is provided according to an embodiment of the invention. The bumper includes a bumper shell formed of an at least partially resilient material and includes an inner surface that mates to the vacuum cleaner chassis and an outer surface. The bumper shell is affixed to the vacuum cleaner chassis as an integral component of the vacuum cleaner and the outer surface of the bumper shell becomes a portion of an outer surface of the vacuum cleaner. The bumper further includes one or more cavities formed along a bottom edge region of the bumper shell, one or more corresponding magnets designed to fit into the one or more cavities, a backing plate including one or more fastener apertures, and one or more fasteners that pass through the one or more fastener apertures of the backing plate and affix the backing plate to the bumper shell.
