  • Patent number: 5882773
    Abstract: Variable index optical single-layers, optical multilayer, and laser-resistant coatings were made from a perfluorinated amorphous polymer material by physical vapor deposition. This was accomplished by physically vapor depositing a polymer material, such as bulk Teflon AF2400, for example, to form thin layers that have a very low refractive index (.about.1.10-1.31) and are highly transparent from the ultra-violet through the near infrared regime, and maintain the low refractive index of the bulk material. The refractive index can be varied by simply varying one process parameter, either the deposition rate or the substrate temperature. The thus forming coatings may be utilized in anti-reflectors and graded anti-reflection coatings, as well as in optical layers for laser-resistant coatings at optical wavelengths of less than about 2000 nm.

    Abstract: A dry transfer decal is formed when a lithographic image is printed onto a transparent UV-dipped base sheet. Additionally, the decal includes opaque layers, a removable adhesive, and a release liner with a backing sheet. The lithographic decal provides an art-quality image, in a large format, which has vivid colors and precise graphic detail. The opaque background layers increase the brightness of the image colors and covers over any underlying logos when affixed to a display surface. The UV absorbing base layer reduces the strength of UV rays reaching the transfer image thus the decal resists fading even after prolonged exposure to sunlight. The base layer also prevents abrasion and scratching which is prone to occur in active environments.

  • Patent number: 5789068
    Abstract: The invention provides a solder preform coated with a predetermined thickness of parylene which physically and chemically protects the preform, as well as a provides a unique optical interference coating which reflects at characteristic frequencies. When predetermined thicknesses of parylene are selected, the parylene coating provides an interference coating which causes the solder preforms to appear green, or gold, or blue in color. The parylene coating, which is otherwise colorless and transparent thus enables solder preforms to be visually distinguishable by alloy type (or customer) by the use of colors, or blends of colors. The invention further provides an effective method of visually verifying the reflow status of a solder preform during manufacturing by examining the color of the solder preform after heating.

  • Patent number: 5756211
    Abstract: The invention relates to high filler content plastic molded articles, which articles have a surface having a pronounced glitter appearance resembling that of a microcrystalline mineral material. The glitter effect is obtained by incorporating glitter-producing particles having a plastic basis and a specific gravity <2, in the composition of said articles. A method of manufacturing such molded articles is described, according to which all of the components are adjusted to corresponding densities. The products have a particularly durable simulated-rock appearance with good glitter characteristics.

  • Patent number: 5741572
    Abstract: A paper or transparency receiving toner to be fixed by heat has an ionomeric resin on its outer surface. For universal application, the outer layer is a blend of non-ionomeric resin, such as styrene acrylate copolymer, and an ionomer, which permits the material of the toner to molecularly intermingle with the blend during heat fixing. Irradiation raises the melting point of the ionomeric resin to prevent delamination. The resulting printing is strongly bonded to the substrate and is of excellent quality.
