Abstract: A rolling mill with oil-cooled top and bottom work rolls at the entry side and a water spray header at the exit side of the bottom work roll. Water cooling is used below the pass line, reducing the heat in the mill substantially without the risk of generating drip-related surface defects during rolling. Water cooling can be used on the bottom work roll and a portion of the oil no longer needed to cool the bottom work roll can be diverted to the top work roll. In some cases, the coolant portion of the flatness control can be operated solely through water-cooling the bottom roll.

Abstract: Provided are a manufacturing method and manufacturing device that allow the depth of rack teeth to be adequately maintained across the axial direction. A stepped surface (47) is provided on one surface in the axial direction of a pressure punch (46) that moves together with a teeth-forming punch (32). The teeth-forming punch (32) is displaced downward and rack teeth are formed on the upper surface of an intermediate material (23). At the same time, the surface on the end in the axial direction of the intermediate material (23) is pressed in the axial direction by a movable die (41a) due to the engagement between the stepped surface (47) and the surface on the other side in the axial direction of the movable die (41a).

Abstract: Example valve stem and plug connections and example staking tools are described herein. An example apparatus includes a valve plug having a first side, a second side opposite the first side and a bore extending from the first side to the second side. A first portion of the bore is tapered from a first diameter to a second diameter smaller than the first diameter. A valve stem is disposed within the bore of the valve plug. The valve stem includes a first section, a second section and a third section between the first and second sections. The third section is tapered from a third diameter to a fourth diameter smaller than the third diameter. The tapers of the first portion of the valve plug and the third section of the valve stem, when engaged, create a frictional force that resists movement of the valve stem out of the bore.

The method includes moving the first forming portion of the first forming member and the first forming portion of the second forming member across the axis in a second direction that is substantially opposite the first direction to draw and form the formable material over the first forming portion of the second forming member, disengaging the first forming member from the formable material, and moving the first forming member to position a second forming portion of the first forming member to face the formable material.

Abstract: Disclosed are a method and system to form a contoured structure using deep rolling. The method includes using deep rolling to introduce plastic deformation to one or more portions of a work piece to form a convex contour in the work piece. The work piece, and subsequently formed contoured structure, can be metal or composite. The disclosed deep rolling systems and methods form, for example contoured aircraft panels, while also providing fatigue strength improvement and low level of work hardening during the forming process rather than as a post-production surface treatment.

One method for forming the can forms the lidding material by using an outwardly extending curl (20) at one end of the metal can body as the draw die. Lidding material which is carried by the body maker punch is drawn around the curl of the can body draw die so as to form the lidding material into a cup shape.

Abstract: The profile shape of the vessel body and of handle portion is formed from a single sheet of metal to create a flat by cutting, stamping or blanking. An opening is created in the handle portion to reduce heat propagation. The shape of the pan body is formed by spinning with the flat handle portion. The handle is formed by creating three-dimensional contours in the handle portion of the blank. The neck portion has a flat section adjacent the pan body followed by sections of different curvature. One section of the neck portion has a deeply curved cross-section. That neck portion transitions to the hand grip portion which has a reduced curvature, particularly toward the unattached end of the handle. The neck portion may have a “W” cross sectional shape.

Abstract: A transport system has a dedicated trailer for transporting a small transport reel (i.e., <18-ft in diameter) of continuous rod to the field. The trailer has a pedestal that can pivot the reel. A hub motor on the pedestal can turn the reel, and a transfer unit and rod bender on the trailer can curve or straighten the rod when being fed into or out of the reel. A power and hydraulic system operates the various hydraulic components on the trailer. In other aspects, the transport system includes stands that can hold the small transport reels on a trailer within a defined transport envelope. When empty, these stands can be stacked on top of one another on the trailer for return to a facility.

Abstract: A stent is formed from a wire having an outer member, a radiopaque member lining at least a portion of the outer member inner surface, and a lumen defined by the outer member inner surface or the radiopaque member inner surface. A substance is disposed in the lumen to be eluted through at least one opening disposed through the outer member to the lumen. The radiopaque member may be substantially continuous along the length of the wire or disposed only along portions of the wire such as crowns. In a method for making the stent, a composite wire including an outer member, a radiopaque intermediate member, and a core member is shaped into a stent pattern and processed to remove the core member and optionally portions of the radiopaque intermediate member, without damaging the outer member.

Abstract: The polymeric pipes reinforced with a metal casing are used for transporting oil and gas, acids, alkali products, drinking water and industrial water, and also in the transportation of aggressive and neutral pulps. A metal-containing polymeric reinforced pipe includes a welded metal casing and a polymeric matrix having an amorphous-phase-based molecular structure. The metal-containing polymeric reinforced pipe is produced by extrusion moulding with simultaneous feeding of a polymer melt and the reinforcing metal casing into the mould cavity, followed by intensive cooling of the internal and external surfaces of the pipe being moulded. The invention increases the quality and endurance limit in the radial direction of the metal-containing polymeric reinforced pipe, productivity of the process for manufacturing the pipe, and also the strength and technological effectiveness of a pipeline constructed from the pipes produced.

Abstract: Embodiments of the invention comprise forming a billet from molten steel and hot rolling the billet to reduce the cross sectional area of the billet. Thereafter, the billet is hot rolled into a lead pass bar having a cross-sectional area comprising a reduced width dimension located adjacent to the center longitudinal axis of the bar. In one embodiment of the invention, the billet can be formed into a lead pass bar having a cross-sectional area in the shape of an hourglass or peanut by feeding the billet through a first set of rolls. After the lead pass bar is formed, it is passed through a second set of rolls in order to form the substantially continuous threaded rebar without longitudinal ribs. The cross-sectional area of the lead pass bar helps to produce a substantially continuous threaded rebar product without longitudinal ribs using standard rebar manufacturing tooling and equipment.
