  • Patent number: 4465543
    Abstract: An apparatus transposes a matrix of semiconductor pellets mounted on a first adhesive tape to a second adhesive tape in such a manner that the respective pellet rows are arranged spaced from the adjacent pellet rows. It has pellet-supporting means having an inclined plane and apical plane. The first adhesive tape bearing the matrix is carried stepwise along the inclined plane toward the apical plane to successively bring the respective rows of the matrix to the apical plane. Above the apical plane, a second adhesive tape is carried in a direction intersecting the pellet columns at right angles with the adhesive plane thereof facing the matrix. When each row mounted on the first tape is on the apical plane, the second tape is pressed against the row. Each time one pellet row is transposed to the second tape, the pellet-supporting means is shifted in a direction intersecting the pellet columns at right angles.

  • Patent number: 4420515
    Abstract: A process for preventing the counterfeiting of valuable documents through use of photography, photocopying techniques, or other methods of counterfeiting. The process includes laminating an extremely thin metallic film to the substrate of the valuable document before the document is printed with the area of the metallic film being small in comparison to the area of the document. The metallic film can be located anywhere on the face of the document and a "latent image" is embossed on the metallic film when the document is printed. Embossing the latent image on the metallic film, rather than on the document substrate, provides many advantages not possible in the prior art.A photocopy of a document containing the embossed metallic film does not include the latent image and a color photocopy will be different in color than the original document. Therefore, a lay observer can readily differentiate between a genuine document and a counterfeit document.

  • Patent number: 4407685
    Abstract: A release film is coated with a thin layer of metal by, for example, a vapor deposition process. The film is then stretched over a composite object, made, e.g., of fiberglass-epoxy or graphite-epoxy, which one desires to metallize. A treatment involving either vacuum or pressure and that may involve heat is used to transfer the thin metal layer to the composite object. The stretchable film is then peeled off the object, leaving a metal coating bonded to the object. The epoxy resin or other adhesive in the composite material gives structural integrity to the object as well as provides a bond for the metal, so that the composite object may be molded and metallized in one step. Alternatively, a two-step process of molding then metallizing or metallizing then molding can be employed.

  • Patent number: 4398985
    Abstract: A laminated construction having differential release characteristics is provided which will yield a self-detackifying adhesive surface upon delamination. The laminate is produced by coating a film of a polymeric material onto one side of a face stock material and then laminating this construction to an adhesive which has been coated onto a release liner. The release liner is removed and the remaining portion of the laminate is affixed to a suitable substrate utilizing the exposed adhesive surface. The polymeric material is chosen so that upon delamination of the face stock from the substrate, it remains affixed to the adhesive coating. This results in a self-detackified adhesive surface on the substrate. The laminate construction is useful for tags, labels, stickers, and the like as well as for sending credit, business, or membership cards on preprinted mailers to ultimate users.

  • Patent number: 4329779
    Abstract: A method of applying microelectronic circuit elements, such as high definition thin-film microwave components, typically to a lower definition thick film or printed circuit board substrate. The method described involves the formation of a high definition microwave filter on the surface of a transparent, flexible carrier substrate using thin film deposition techniques, and the circuit element is then adhesive bonded face down in an appropriate position in a thick film circuit on the surface of a second, permanent substrate. The thin film circuit element is formed with contact areas which overlap cooperating portions of the thick film circuit on insertion of the circuit element to provide electrical connections. The carrier substrate may then be removed, eg by dissolving, and the overlapping contact areas may be permanently bonded together. Thus only the high definition parts of the micro-circuit need be fabricated using expensive thin film technology.

The chamber is lowered with a vertical oscillatory motion, while a slight vacuum is applied, to lower the articles into the cavities and engage them intermittently with the walls of the cavity. This orients and centers the articles in the cavities. A substrate, having sites to which the articles are to be bonded, is coated with a liquefiable substance to render the sites adherent. The substrate is then positioned over the cavities.

  • Patent number: 3971692
    Abstract: Retro-reflective material is made by applying a mono-layer of transparent glass beads to a tacky coating formed on a carrier sheet, coating exposed parts of the beads with a reflective material such as aluminium, and embedding the reflectively coated parts of the beads in an adhesive coating on a backing member. The carrier sheet is then stripped off. The thickness of the adhesive coating on the backing member is less than the typical diameter of the beads, and the thickness of the tacky coating on the carrier sheet is less than that of the adhesive on the backing member. In some cases screens or stencils are interposed between the carrier sheet and the backing member. Products resulting from these processes are described.

  • Patent number: 3956041
    Abstract: There is provided a process for producing resin rich surfaces of desired and specified thickness and physical, chemical, electrical and/or optical properties involving the use of a transfer base material to move a viscous, liquid, hardenable composition after partial hardening into a non-tacky state into contact with the surface of a second, permanent base, completing the hardening of the composition into a resin-rich surface layer adhering to the second base and subsequently removing the transfer base therefrom. In specific embodiments, the permanent base itself can be hardenable and complete hardening is effected simultaneously; the surface layer can be an adhesive layer; and the surface layer can be catalytic throughout to electroless metal deposition.

  • Patent number: 3930921
    Abstract: An improved method of finishing leather by transferring a finish coating, at least the outer stratum of which comprises a thermoplastic, adhesive acrylic polymer, from a release layer bearing the finish coating to the leather. The leather to be coated (which may be supported on an appropriate backing layer) and the release layer are pressed into a sandwich-like assembly with the concurrent application of sufficient heat and pressure to transfer substantially the entire finish coating to the surfaces of the leather and the backing layer juxtaposed therewith. Transfer of the finish coating is effected without the application of any adhesive material or "tie coat" prior to pressing the coating into contact with the leather, by virtue of the thermoplastic, adhesive characteristics of the acrylic finish coating per se.The method may be carried out batch-wise employing discrete backing and release layers for the transfer of finish coatings to individual leather pieces.
