Patent number: 5654084Abstract: An enhanced protective coating to prevent interaction between constituents of the environment and devices that can be damaged by those constituents. This coating is provided by applying a synergistic combination of diffusion barrier and physical barrier materials. These materials can be, for example, in the form of a plurality of layers of a diffusion barrier and a physical barrier, with these barrier layers being alternated. Further protection in certain instances is provided by including at least one layer of a getter material to actually react with one or more of the deleterious constituents.

Patent number: 5370913Abstract: A laminated ornamental glass article has two transparent glass substrates and three coating layers of opaque figures and crevices between the two transparent glass substrates. This allows a person at one side of the glass article to see through the glass article an object at the opposite side of the glass article, while another person on the opposite side may only see the opaque figures on the glass article. The three coating layers include a glaze figure layer, a white paint layer and a dark, ink layer. Each layer has the same figure patterns and the same crevices, the crevices being adapted to be filled with an adhesive material for bonding the two transparent glass substrates.Type: GrantFiled: October 26, 1992Date of Patent: December 6, 1994Inventor: Chii-Hsiung Lin
