Abstract: A method and apparatus for drawing tubular stock continuously and simultaneously through at least two successive drawing dies having mandrels located in the dies and within the tubular stock. The method comprises the steps of continuously pulling the tubular stock through the first one of the dies by a rotating capstan containing turns of the stock, the capstan simultaneously directing the stock to the second of one of the dies. From the second die, the stock is continuously pulled, the pulling of the stock continuously through the dies effecting a simultaneous reduction of the cross sectional area of the stock, with a single pass of the stock through the dies.

Abstract: A method of forming an integral rivet in a sheet element including providing cooperating male and female dies and an interposed sheet element, moving the male die toward the female die to draw an outwardly directed hollow boss. Continuing movement of the male die toward the female die to thin an annular region in the lower portion of the hollow boss by compression which establishes metal flow substantially entirely in the direction of the upper portion of the hollow boss. Continuing relative closing movement of the male die with respect to the female die to establish an annular band of thinned material extending upwardly toward the upper portion of the hollow boss, whereby the upper portion of the hollow boss has a thickness substantially equal to the thickness of the remainder of the sheet element. The sheet element may be peripherally restrained around the area in which the boss is formed during boss formation. Apparatus for fabricating an integral rivet in sheet material including a male die having a convexly curved sheet contacting surface and a rearwardly disposed generally cylindrical surface. A female die having a bore defining wall and a peripheral material supporting surface disposed substantially perpendicular to the bore defining wall. An annular concave transition surface connecting the bore defining wall and the material supporting surface. The radius of curvature of the sheet contacting surface and the radius of curvature of the annular concave transition surface being such that movement of the male die toward the female die establishes relative closing movement between the dies which occurs initially at the outer portion of the annular concave surface of the female die and progresses inwardly along the surface as male die movement continues.

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 container assembly for providing a sterile sealed container including a container having a neck provided with an annular mouth defining bead and a multipiece closure having a sealing member, a locking member and a cover secured thereto. The mouth defining bead has an upper surface, an exteriorly disposed downwardly and inwardly inclined closure anchoring shoulder defining surface and an outer surface connecting the upper surface with the shoulder defining surface. The locking member has a top panel with an opening therein and a depending skirt which has a lower surface radially inwardly deformed into locking engagement with the anchoring shoulder. At least two radially outstruck lugs formed within the locking member skirt. A portion of the sealing member compressively secured between the locking member and the container neck. The cover having a top panel and a skirt having a lower portion deformed radially inwardly to a diameter less than the diameter of the locking member taken at the position of at least one outstruck lug. At least one radially inwardly directed embossment formed in the cover skirt at a height generally the same as the lugs. Rotation of the cover with respect to the locking member causes the embossment to permanently inwardly reform the outstruck lugs and permit relative axial separation of the closure and locking member.
