    Abstract: A method and apparatus for extruding metallic tubes or pipe of varying wall thickness so as to maintain proper tube dimensions at the time of changing from one wall thickness to another during the extrusion operation. The apparatus includes an extrusion press having a ram with a mandrel slidably mounted therein and a stationary die. The mandrel has a stepped tip which is adapted to enter an opening in the die, and the maximum diameter of the mandrel is the same as the diameter of the die opening. The ram is advanced to extrude the flowable charge while one stepped portion of the mandrel tip is disposed within the die opening, but the ram is stopped while the mandrel is moved to present a different stepped portion of its tip to the die opening. At such time, the mandrel alone is moved to extrude the flowable material, and the mandrel is moved at a speed which is the same as the speed of the material, whereby at the time of the changeover the extrusion ratio of material flow to the speed of the mandrel is maintained at unity.

    Abstract: A method of fabricating a laminated metal container wall provided with an opening device including providing a metal sheet having a layer of protective material secured thereto by means of an adhesive selected from the group consisting of epoxy, polyester and polyurethane. The protective material is selected from a group consisting of a copolymer of a polyolefin and ethylene and ionomers of polyolefin. A preferred form of copolymer has polypropylene as the polyolefin employed with the ethylene. A preferred polypropylene ethylene copolymer may have an ethylene content of about 2 to 10%. The laminated metal sheet is scored to define a removable sector therein. The scoring is preferably effected to such a depth as to provide residual metal along the score line of about 2 to 6 mils. Simultaneously with the scoring operation, reducing the thickness of the layer of protective material without penetrating entirely through the layer. The protective layer may have an initial thickness of about 1.5 to 4 mils and preferably about 2.5 to 3.5 mils. A laminated metal container wall having a score line defined removable sector. An adhesive material secured to one surface of the container wall. A continuous layer of protective material secured to the metal panel portion by means of the adhesive. The protective layer may have a thickness of about 1.5 to 4 mils and is selected from a group consisting of a copolymer of a polyolefin and ethylene and ionomers of polyolefins.

    Abstract: Decorative plate or sheet having an attractive textured surface is continuously cast in an open ended chilled mold. The freezing plate ingot has a surface solidified in a varying and cyclic fashion by applying thereto a volatile lubricant at a rate much higher than that normally employed in similar casting arrangements. The resulting plate exhibits a textured surface with accompanying variations in composition and metallurgical structure such that the response to electrolytic anodizing treatments varies and the anodized surface exhibits varying shades and colors.

    Abstract: A method of making a hollow metal ball bat having a wall thickness along the length thereof that is substantially uniform thereby providing a weight ratio for the handle and barrel portions of the bat that approximates the diameters of the handle and barrel portions. The handle portion of the bat is formed by a swaging process which reduces the diameter of a portion of a metal tube blank, having generally a uniform diameter and wall thickness, on a mandrel having a substantially uniform diameter. The mandrel is effective to maintain the uniform wall thickness of the blank by forcing the metal thereof to flow longitudinally from the end of the blank forming the handle portion of the bat.
