    Abstract: A bending device for forming a corrugation in a metal sheet, the bending device having a frame, a die having two die elements, each having a concave half-impression, mounted able to slide on the frame; a punch having a head able to engage inside the impression of the die so as to press the metal sheet; and two side clamps mounted sliding and able to move vertically with respect to the lower frame so as to clamp the metal sheet against the bearing surfaces of the die elements. During the displacement of the punch into its bending position, the metal sheet transmits a traction force to the die elements and to the side clamps so as to displace them into their near position.

    Abstract: The present invention is directed to an improved metal strips straightener, including an infeed device and a pressure frame. The infeed device has one or more leveling rollers, and the pressure frame has a roller frame. The roller frame has one or more roller blocks to bring a metal strip into a upward full encirclement wrap. Each roller block is attached with a camshaft, where each camshaft is connected to a motorized drive system. Rotation of the camshafts actuates the roller blocks to move the metal strips, applying pressure on the metal strips during the passing through of the roller blocks. A closing cylinder is attached to one end of a roller block, where the closing cylinder has a convex contact surface. Multiple roller blocks are connected to each adjacent roller blocks via their connected closing cylinders.

    Abstract: A method of forming a stent includes the steps of forming a composite member into a stent pattern, forming openings through an outer member of the composite member, processing the composite member to remove a portion of the composite member without adversely affecting the outer member, and swaging the outer member to create a plurality of lumens. The composite member may be formed of an outer member with an hourglass-shaped inner member, wherein the processing step removes the inner member and the swaging step forms two lumens from the hourglass shaped cavity. The composite member may be formed of an outer member, an inner member, and an intermediate member, wherein the processing step removes the intermediate member and the swaging step presses portions of the outer member into contact with the inner member to form two lumens separated by the inner member.

    Abstract: The present invention describes a drill pipe in which various sections of the pipe are strengthened, or their shape is altered, in order to improve the wear and buckle resistance of the drill pipe. The sections are strengthened using various hardening methods such as heat treatment processes and/or expansion techniques. A sleeve can also be applied to the strengthened portions. Surface enhancers, such as hardbanding, can be applied to the strengthened portions or the sleeve in order to provide abrasion resistance or to reduce friction.

    Abstract: Apparatus for reducing the diameter, rounding or straightening of pipe or tubing by rolling comprising a plurality of cylindrical rollers arranged in a parallel-cylindrical array through which the pipe or tubing is passed, the rollers being skewed to displace their central contact zones radially inwards bringing them into forceful contact with the external surface of the pipe or tubing, and being rotated to cause the central contact zones to describe helical paths along the external surface of the pipe or tubing. Thereby to progressively apply locally to the whole of the external surface of the pipe or tubing a compressive force in excess of the yield strength of its material, causing the pipe or tubing to adopt a set at a smaller diameter.
