  • Patent number: 6238729
    Abstract: Apparatuses, systems, and methods are disclosed for providing optical communications. Bragg grating used in the optical components and systems of the present invention are produced by selectively hydrogenating one or more selected sections of an optical waveguide in general, and particularly optical fiber. Selective hydrogenation can be performed by selectively establishing local conditions in a first environment conducive to introducing greater quantities of hydrogen into selected sections than into non-selected sections, which are maintained in a second environment. The extent of selective hydrogenation and the hydrogen concentration difference between selected and non-selected section of the waveguide is a function of the temperature, pressure, and time of exposure established in the first and second environments.

  • Patent number: 5110702
    Abstract: A process is provided for the non-electrostatic transfer of a toned image. Using an intermediate transfer roll from an element to a receiver, a developed toned image on the surface of an element is transferred by pressure and heat to a transfer roll. The heat is sufficient to sinter the toner particles to each other. The roll is then positioned against a receiver and rolled thereover and the toned image is transferred to the receiver. If the combination of heat and pressure is sufficient, the transferred toned image is fused to the receiver during the transfer; if not, then the transferred image can be subsequently fused to the receiver. The process is suited for producing high resolution images from very small particle size toner powder on rough paper.

    Abstract: A thermoplastic stretch wrap film exhibits a significant level of cling on one surface but no appreciable cling force on the other, the latter surface exhibiting a slide property when in contact with a film or like surface due to the presence of particulate antiblock agent mechanically bonded thereto. The film can be used to overwrap one or a group of articles to form a unitized packaged unit employing any of the known and conventional tension-wrapping techniques. Because of its one-sided cling and slide capabilities, pallet loads overwrapped with the film and in mutual contact avoid film tearing or destruction when the pallet loads are separated from each other.

  • Patent number: 4833117
    Abstract: Correction compositions for correcting markings provided on the surface of a pressure-sensitive chemical recording medium carrying a developer material which comprises an acidic developer by interaction of the developer material with a color-providing material. The compositions comprise a substantially uniform dispersion of an opacifying pigment, a polymeric film-forming material, and a Lewis acid. The composition is applied to a marking to provide a film which covers the marking, and a visible corrected marking can be provided on the film by applying a pattern of color-providing material corresponding to the corrected marking to the film.

  • Patent number: 4815872
    Abstract: Method and apparatus for the thermal transfer printing upon a record medium utilizing a print ribbon so as to form a protective transparent layer over a printed area upon a record medium. The thermal transfer print film includes plural colored ink regions separated by transparent ink regions. The method and apparatus of the present invention thus provide for the initial printing via thermal transfer of the colored ink regions onto an area of the record medium. Subsequent alignment of a region of the transparent ink with the printed area on the record medium and selective operation of thermal print heads thus thermally transfers portions of the thermal transparent ink to the previously colored ink printed area to provide a transparent ink layer over the printed information upon the record medium thereby protecting the same.

  • Patent number: 4810522
    Abstract: A method and apparatus for electrostatically applying a layer of coating material to a moving substrate. In a preferred embodiment, a threaded shaft formed of dielectric material, having one end thereof coupled to a drive motor, has a portion of its threads mounted for rotation through a bath of coating material. An electrostatic field of predetermined magnitude is established between the coating material and a substrate surface spaced therefrom. The electrostatic field atomizes coating material accumulating on the ridge portion of the rotating thread and subsequently deposits a layer of the atomized coating material on the adjacent substrate surface as it is moved past the rotating dielectric thread at a predetermined angle with respect to the axis of rotation of the threaded shaft.

  • Patent number: 4760010
    Abstract: In a printing system for printing an image on a recording sheet, adopted as the recording sheet is a sheet coated with microcapsules on one surface thereof. Each microcapsule envelopes a first component therein while the sheet itself holds a second component. The color of second component is changed when mixed with the first component. The microcapsule further envelopes a third component which increase the mechanical strength of microcapsule when light is projected thereto. An image is formed on the recording sheet by selectively rupturing the microcapsules in accordance with the image to be printed thereon, and the unruptured microcapsules remaining on the recording sheet are then hardened by exposing a light thereto and thus the image printed on the recording sheet is fixed thereon.

  • Patent number: 4708887
    Abstract: In a method and apparatus for coloring polymer-insulated wire, the wire is guided through a solvent reservoir to dissolve surface contaminants and etch the surface of the insulation, and passed between opposed wiping surfaces to wipe surface contaminants from the wire. The wire is then passed through a hot air duct to evaporate solvent remaining on its surface. The dried wire is guided through a solvent-based colorant reservoir to coat it with colorant and passed against a wiping surface to wipe excess colorant from its surface. The coated wire is passed through a hot air duct to evaporate some of the solvent in the colorant, and through a cold air duct to harden an outer surface of the colorant before it passes over a guide wheel. The hardened surface prevents adherence of the colorant to the guide wheel. The coated wire is passed by a spraying device which intermittently sprays solvent-based colorant on the wire to band encode it.
