  • Patent number: 6852419
    Abstract: A coated article is provided so as to include a solar control coating having an infrared (IR) reflecting layer sandwiched between at least a pair of dielectric layers. The IR reflecting layer includes NbCr and/or NbCrNx in certain embodiments of this invention. The use of such materials as an IR reflecting layer(s) enables the coated article to have good corrosion resistance to alkaline solutions, good mechanical performance such as scratch resistance, and/or good color stability (i.e., a low ?E* value(s)) upon heat treatment (HT). The coated article may be heat treated (e.g., thermally tempered) in certain example embodiments of the invention.

  • Patent number: 6849343
    Abstract: Interference pigment flakes and foils are provided which have color shifting properties. The pigment flakes can have a symmetrical coating structure on opposing sides of a reflector layer, can have an asymmetrical coating structure with all of the layers on one side of the reflector layer, or can be formed with encapsulating coatings around a core reflector layer. The coating structure of the flakes and foils includes a reflector layer, a dielectric layer on the reflector layer, and a titanium-containing absorber layer on the dielectric layer. The pigment flakes and foils exhibit a discrete color shift so as to have a first color at a first angle of incident light or viewing and a second color different from the first color at a second angle of incident light or viewing. The pigment flakes can be interspersed into liquid media such as paints or inks to produce colorant compositions for subsequent application to objects or papers.

  • Patent number: 6846558
    Abstract: A dense or porous coating of material is deposited onto a substrate by forcing a colloidal suspension through an ultrasonic nebulizer and spraying a fine mist of particles in a carrier medium onto a sufficiently heated substrate. The spraying rate is essentially matched to the evaporation rate of the carrier liquid from the substrate to produce a coating that is uniformly distributed over the surface of the substrate. Following deposition to a sufficient coating thickness, a single sintering step may be used to produce a dense ceramic coating. Using this method, coatings ranging in thickness from about one to several hundred microns can be obtained. By using a plurality of compounds in the colloidal suspension, coatings of mixed composition can be obtained. By using a plurality of solutions and separate pumps and a single or multiple ultrasonic nebulizer(s), and varying the individual pumping rates and/or the concentrations of the solutions, a coating of mixed and discontinuously graded (e.g.

In the MeX layer the quotient QI as defined by the ratio of the diffraction intensity I(200) to I(111) assigned respectively to the (200) and (111) plains in the X ray diffraction of the material using ?-2? method is selected to be ?1. Further, the I(200) is at least twenty times larger than the intensity average noise value, both measured with a well-defined equipment and setting thereof.

  • Patent number: 6838180
    Abstract: The invention concerns transparent fire break glass panels. The inventive glazing comprises at least two glass sheets and an intumescent phosphate-based material layer, layer which is located between said two glass sheets. The intumescent material comprises pyrogenous silica or a mixture of pyrogenous silica and alumina which enables said material to be exempt from creep deformation at temperatures preceding the expansion of the intumescent material in fire resistance tests. The inventive glass panels have proved heat resistance, and are more easily manufactured than similar glass panels in prior art.

  • Patent number: 6827883
    Abstract: An optical fiber preform (1) serving as a material of an optical fiber has a shoulder portion (12) thrusting beyond a middle portion (M) in a base end region (K) which is on the upper side when the optical fiber preform is suspended for a drawing process. The optical fiber preform (1) of this configuration can be easily produced by appropriately setting the heating condition, etc. for the sintering step in the production process. Thus, it is possible to omit the elongating step after the sintering step, thereby simplifying the production process. Further, in the prior-art technique, turbulence is generated in the gas flow in the furnace of the drawing apparatus toward the end of the drawing step, making it impossible to draw in a stable manner.
