The tool comprises a shell having a body portion and an upper mold surface having a grain texture, at least the body portion comprising a nickel-iron alloy having a coefficient of thermal expansion of at most 5.0×10?6 in/in/° F. at temperatures between 100° and 500° F.

Abstract: A system is provided for drilling a borehole into an earth formation, comprising a casing arranged in the borehole, a drill string extending through the interior of the casing to a lower end portion of the borehole, and a body of drilling fluid extending into the casing, the casing having an inner surface susceptible of wear due to frictional contact with an outer surface of the drill string during drilling of the borehole with the drill string. The system further comprises means for reducing wear of the inner surface of the casing, the means including at least one of a hardened layer at the inner surface of the casing, a friction-reducing layer at the outer surface of the drill string, and a lubricating compound contained in the body of drilling fluid.

Abstract: A metal surface infused composite object made by thermal spraying a metal material onto a release agent coated pattern, followed by vacuum infusion at least a portion of the metal material layer with a resin and then separating the composite infused metal object from the pattern.

Abstract: The present invention relates to a novel method of venting a spray metal molding surface. More particularly the invention relates to a method of manufacturing a mold using a thermal spray process to produce a metal surface containing passages in the spray metal to vent fluid or gas from the forming surface. The present invention is primarily intended for mold tools, such as vacuum molds, injection molds or blow molds having vents or a multiplicity of holes in the forming surface to evacuate or supply gas in a mold.

Abstract: A method of manufacturing a tubular member.

Abstract: A method of radially expanding and plastically deforming tubular members (10, 100, 200) is provided that includes selecting a tubular member, determining an anisotropy value and a strain hardening value for the selected tubular member (10, 100, 200), multiplying the anisotropy value times the strain hardening value to generate an expandability value for the selected tubular member (10, 100, 200); and if the expandability value is greater than 0.12, then radially expanding and plastically deforming the selected tubular member (10, 100, 200).

Abstract: An apparatus for the radial expansion and plastic deformation of a tubular member.

Abstract: Method and arrangement for spray forming an article. The method includes spraying a plurality of metal streams upon a low-heat resistant model and thereby forming a spray formed article. Each of the plurality of metal streams is composed of moltenized droplets, and as between the plurality of metal streams, each is composed of different constituent elements. In the spray form process, conditions of the metal streams are controlled, particularly around the time that the droplets land, to prevent adverse affects such as melting or burning the master model. The spray conditions are controlled in such a manner that the individual metal droplets forming the metal streams remain substantially segregate. The segregated state is maintained through out solidification so that the resulting spray formed article is composed at least partially of psuedo-alloy.
