Patent number: 8287005Abstract: A lightweight and durable drill pipe string capable of short radius drilling formed using a composite pipe segment formed to include tapered wall thickness ends that are each defined by opposed frustoconical surfaces conformed for self-aligning receipt and intimate bonding contact within an annular space between corresponding surfaces of a coaxially nested set of metal end pieces and a set of nonconductive sleeves. The distal peripheries of the nested end pieces and sleeves are then welded to each other and the sandwiched and bonded portions are radially pinned. The composite segment may include imbedded conductive leads and the axial end portions of the end pieces are shaped to form a threaded joint with the next pipe assembly that includes contact rings in the opposed surfaces of the pipe joint for contact together.Type: GrantFiled: January 3, 2012Date of Patent: October 16, 2012Assignee: Advanced Composite Products & Technology, Inc.Inventors: James C.

Patent number: 4807351Abstract: A method for attaching an end-fitting, such as a yoke-type end-fitting, to a tubular drive shaft of the type used in the drive line of vehicles, comprises the steps of deforming the end of the drive shaft tube such as by swaging it onto a tool or replica of the end-fitting so that the inner diameter of the tube end is less than the outer diameter of the end-fitting; and then press-fitting the end-fitting into the deformed tube end. The resulting attachment is free of slippage that otherwise results from directly swaging the tube end onto the end-fitting. A preferred embodiment employs smooth undulating splines on the end-fitting and an outer sleeve over the tube end and utilizes electromagnetic-induced swaging.Type: GrantFiled: February 18, 1988Date of Patent: February 28, 1989Assignee: ASEA Composites, Inc.Inventors: Kenneth R. Berg, Roger L. Sundquist, Liem V. Truong
