  • Patent number: 9272949
    Abstract: Certain example embodiments of this invention relate to the development of temperable UV blocking coatings having enhanced UV blocking efficiency and aesthetic appearance on stock sheets of glass substrates using large-scale wet coating manufacturing methods. A glass substrate is provided. A base coat is curtain coated on the glass substrate from a oxide precursor material including zinc, cerium, titanium, and silicon precursor materials. The base coat is cured. A top coat is roll coated, directly or indirectly, on the base coat, with the top coat being a sacrificial cross-linked organic polymer-based layer. The substrate is heat treated with the base coat and the top coat thereon. The base coat and the top coat are substantially uniform in thickness, and the heat treating removes substantially all of the top coat while causing substantially no cracking in the base coat.

    Abstract: A method of making a strengthened glass article includes providing a flat glass article having a select contour and a glass surface covered by a protective coating layer. The protective coating layer is removed from the glass surface without touching the glass surface with any solid object. Immediately after the protective coating layer is removed from the glass surface, the flat glass article is subjected to an ion-exchange process to strengthen the flat glass article and improve the resistance of the flat glass article to subsequent damage.

  • Patent number: 7021083
    Abstract: A glass tube for use in an optical fiber preform is produced by applying a first soot on an end face of a starting member to form an elongated, porous cylindrical soot core having a first density, and applying a second soot including SiO2 on the periphery of the soot core to form a porous soot cladding having a second density greater than that of the soot core at the periphery of the core. The core and the cladding are later heated together at a temperature sufficient for sintering to form a core glass and a cladding glass. Because the soot core collapses at a greater rate than the soot cladding during sintering, the core glass separates or delaminates radially from the cladding glass. The core glass is then removed from the surrounding cladding glass, and the latter is treated to provide a high purity glass tube suitable for use as part of an optical fiber preform.

    Abstract: An index-matching coating is applied directly to a low-emissivity (“lowE”) thin-film coating. Nodules growing from a site in the lowE coating are removed to avoid propagation of defects through the layers of the index-matching coating. A tempering step in an oxygen-containing atmosphere produces compressive stress in the lowE coating and hardens the coating. The compressive stress facilitates removal of the nodules and the hardening allows mechanical cleaning of the lowE coating prior to the index-matching coating, further removing nodules. Magnesium-fluoride is used as the final layer of the index-matching coating in one embodiment to improve abrasion resistance. The resulting glass panel may be used as a display panel in a plasma display or an organic light-emitting diode display, for example.

The substrate having rib structures is then dipped into a solution containing an opaque pigment which is absorbed into the rib structure.

  • Publication number: 20020092324
    Abstract: A new method is disclosed for producing thin plates by sintering a thin gel plate (e.g., silica) made using a sol-gel process, which substantially eliminates warpage of the plate during the sintering step. Sintering a sol-gel based silica plate to a dense glass typically causes significant shrinkage, and this can cause the plate to curl, especially around its edges. This phenomenon is referred to as warpage. In the method of the invention, the sintering step is performed while the gel plate is mounted on a support surface, separated by a thin layer of refractory powder. At the high sintering temperature, the powder partially fuses and sticks to both the gel plate and the support surface, which prevents non-uniform stresses in the gel plate from warping the plate.

  • Patent number: 6393868
    Abstract: The present invention relates to a novel process for the production of sequences of interference layers composed of layers i of prescribed thicknesses d(i) and refractive indices n(i). In this process a stack of at least two layers i of glasses having refractive indices n(i) and thicknesses d0(i), which are each larger than the predetermined thicknesses d(i) by the same multiplying factor, is provided. The stack is heated to a temperature above the transformation temperature of the glasses and during or after heating, the stack is drawn in such a manner that the individual layers obtain the prescribed thicknesses d(i). After this the drawn stack is cooled.

    Abstract: A method of manufacturing an optical head having a near-filed light generating element that condenses a luminous flux on an exit surface. The generating element has a reflecting or light intercepting film formed on the exit surface and is fixed to a holding member to form an optical head. A minute opening is then formed in the reflecting or light intercepting film by use of light emitted from a first or second light source.

  • Patent number: 6128927
    Abstract: A method for controlling a bore diameter of an optical fiber ferrule is disclosed. The diameter of the bore is controlled by collapsing the ferrule around a rod inserted in an over-sized bore formed therein. The diameter of the rod is selected to match the diameter of the optical fiber to be supported by the ferrule. Thus, after the rod is subsequently immersed in liquid nitrogen removed from the ferrule, the ferrule has a bore diameter which is defined by the diameter of the rod. Suitable materials for the ferrule and the rod include glass and metal, respectively.

  • Patent number: 5536292
    Abstract: Superior microwave transparent thermal insulations for high temperature microwave sintering operations were prepared. One embodiment of the thermal insulation comprises granules of boron nitride coated with a very thin layer of glassy carbon made by preparing a glassy carbon precursor and blending it with boron nitride powder to form a mixture. The blended mixture is granulated to form a grit which is dried and heated to form the granules of boron nitride coated with a glassy carbon. Alternatively, grains of glassy carbon are coated with boron nitride by blending a mixture of a slurry comprising boron nitride, boric acid binder, and methyl alcohol with glassy carbon grains to form a blended mixture. The blended mixture is dried to form grains of glassy carbon coated with boron nitride. In addition, a physical mixture of boron nitride powder and glassy carbon grains has also been shown to be an excellent thermal insulation material for microwave processing and sintering.
