Abstract: A drilling system for use in drilling a wellbore including a driving mechanism and a separation device disposed upstream of the driving mechanism. The separation device filters at least a portion of any solids from drilling media flowing through a filter flow path of the separation device. The separation device flushes at least a portion of the filtered solids through a flush flow path, through a flush outlet on an outer surface of the separation device, and into an annulus between the outer surface of the separation device and the wellbore. Optionally, the drilling system includes a second driving mechanism and a second separation device disposed above the second driving mechanism.

Abstract: A flush joint high torque thread that achieves superior tensile efficiency and compression efficiency. In one example, the thread of a pin member and a box member includes a thread a chamfer with angled shoulders on each side of the thread to achieve increased torque. The stab flanks each contain a lead-in chamfer extending no further than a thread pitch line. The load flanks are each tapered. The stab flanks engage each other during assembly, but not upon assembly. The load flanks do not engage each other during assembly, and do engage each other upon assembly. The pipe achieves both a 70% tensile efficiency and a 90% compression efficiency.

Abstract: A drilling assembly includes a power section with a housing that rotates in a first direction at a drill string rotation rate. An output rotates a drill bit through a transmission shaft in the first direction at a rotor rotation rate relative to the housing. A bent housing between the power section and the drill bit rotates in a second direction at a variable rotation rate relative to the power housing. The transmission shaft extends through the bent housing. A mechanical brake system adjusts the bent housing's variable rotation rate. The bent housing rotates relative to the wellbore in a rotary mode, but not in a sliding mode. The sliding mode maintains the drill bit's direction and inclination while the drill string rotates. In all modes, the drill bit's rotation rate is the sum of the drill string rate and the rotor rate relative to the power housing.

Abstract: An integrated bearing section includes a mandrel partially disposed within a housing. The bearing section includes spherical members disposed between the mandrel's outer surface and the housing's inner surface. A radial bearing portion is formed by spherical members disposed partially within grooves and engaging a flat profile opposing surface. The grooves may be in the mandrel's outer surface, an outer surface of a mandrel sleeve, the housing's inner surface, or an outer radial bearing's inner surface. The flat profile opposing surface may be on an outer radial bearing's inner surface, the housing's inner surface, the mandrel's outer surface, or a mandrel sleeve's outer surface. A thrust bearing portion is formed by spherical members disposed partially within grooves in two opposing surfaces, such as the mandrel's outer surface or a mandrel sleeve's outer surface, and the housing's inner surface or an outer thrust bearing's inner surface.

Abstract: A flush joint high torque thread that achieves superior tensile efficiency and compression efficiency. In one example, the thread of a pin member and a box member includes a thread a chamfer with angled shoulders on each side of the thread to minimize radial plastically deformation of the shoulders. The stab flanks each contain a lead-in taper extending no further than a thread pitch line from the thread crest. The load flanks are each perpendicular. The stab flanks engage each other during assembly, but not upon assembly. The load flanks do not engage each other during assembly, and do engage each other upon assembly.

Abstract: A fabric pickup device useful for a fabric handling system. The fabric pickup device includes a fluid operated cylinder and piston having four individual fabric clutches attached to the cylinder and aligned with and substantially equality spaced apart from the axis of the piston. Each clutch has a head portion having a plurality, preferably four, resilient pickup fingers spaced apart from one another. A substantially flat actuator plate is attached to the free end of the piston and is oriented perpendicular to the axis of the piston. The actuator plate has a series of apertures for receiving the individual pickup fingers. The openings in the actuator plate are sized such that when the plate is retracted by the action of the fluid cylinder, the resilient fingers of each pickup finger separate and, when the plate is extended, the finger are brought together to grip the top surface of a fabric piece.
