Latest Patents
One of his latest patents is titled "Transparency having a second surface multilayer decorative coating." This invention discloses a coated article, which can be an architectural transparency, vehicular transparency, or a reflecting article, designed as a decorative item. The article features a substrate, typically a substantially transparent one, with an optical coating applied to its surface. The coating consists of a bilayer dielectric thin film that has a thickness corresponding to a constructively interfering function of a specific wavelength. The bilayer thin film includes a metallic layer that acts as an adhesion layer, topped with a dielectric layer made from a compound of the metal forming the metallic layer.
Another significant patent is related to "Plasma chemical vapor deposition SiO.sub.2-x coated articles and plasma." This patent describes a coated stainless steel article and the method for preparing it. The coating is formed through plasma chemical vapor deposition, utilizing a plasma of nitrous oxide, a silane, and an energy transfer agent such as helium or argon. The resulting coating is adherent, corrosion-resistant, and has a thickness sufficient to mask the features of the stainless steel substrate. It also provides a pitting potential in 3.5% NaCl of greater than 600 millivolts, achieving a J.I.S. 8502 (1982) rating versus a saturated calomel electrode in a salt spray test of at least B in 5% NaCl-0.02% hydrogen peroxide.
