Abstract: A master information carrier for magnetic transfer includes a master substrate made of metal, including an embossed pattern corresponding to information to be transferred. The master substrate is produced by laminating a metal disk with a predetermined thickness on an original disk, on which an embossed pattern is formed, by electroforming, peeling off the metal disk and die-cutting a disk in a desired size. An outer diameter of the metal disk is at least 1.7 times longer than an outer diameter of the die-cut master substrate. When the metal disk is peeled off from the original disk, deformation due to the forces acting from the side of the outer circumference is reduced. The flatness of the metal disk is ensured and the transfer qualities are improved. Further, a step of removing distortion of the metal disk, caused at the time of peeling off the metal disk, may also be provided.

Abstract: The invention relates to inflatable fabrics which comprise two separated and distinct fabric layers in discrete areas of such fabrics as well as connecting seam-producing materials to which such fabric layers are simultaneously attached. The resultant inflatable fabric composite thus includes inflatable areas separated, at least partially, by seamed barrier areas. This configuration will form “pillowed” structures within the target fabric upon inflation. Such connecting seam-producing materials are incorporated within the two-layer structure as peel seams in relation with the individual fabric layers. Upon inflation, the seams then act as shear seams which greatly increases the overall strength of the two-layer inflatable fabric. These shear seams thus provide a relatively effective manner of reducing air permeability within the entire fabric article. Such a fabric may be utilized in numerous and various applications wherein fabric inflation is desired or necessary.

Abstract: A closure assembly is provided that includes an outer cap with a skirt dimensioned to telescope over the open top end of the tube. An annular shoulder extends inwardly from the top end of the skirt and includes an aperture through which a needle may be directed. A laminated seal is bonded to the bottom surface of the annular shoulder of the outer cap and extends continuously across the aperture in the annular shoulder. A stopper is secured on the bottom surface of the annular seal and is dimensioned for sealing engagement in the open top of the tube. Outer circumferential portions of the bottom surface of the laminated seal between the skirt and the stopper are bonded to the open top end of the tube. The bond between the closure and the laminated seal is stronger than the bond between the tube and the laminated seal. Thus, the closure assembly retains its structural integrity after opening of the tube and can be used to reseal the tube.
