  • Publication number: 20050223536
    Abstract: A gasket (1) has a gasket core (2) and an outer gasket layer (4) covering the gasket core (2). At least one of the two sealing materials that make up the gasket has two reactive components before they are extruded, with said components chemically reatcting with one another as they are combined and/or extruded. The extruded core may be formed of a two-component resin which is at least one of an elastomer and a foam. The flexible outer layer may be a synthetic resin which is at least one of an elastomer and a foam. The outer layer may be electrically conductive, ultra-violet resistant, or resistant to the environment in which the gasket is to operate.

  • Patent number: 5949188
    Abstract: Electroluminescence color display screen with matrix picture elements (pixels), the display screen comprising a system of single layers applied on top of and partially next to one another, the layer system comprising an insulating, optically at least translucent base layer, a conductive, optically at least translucent base electrode, a patterned electrically insulating intermediate layer, if necessary, one or several color conversion layers applied in form of a matrix and, if necessary, one or several index matching layers, wherein the base electrode is deposited as a continuous layer upon the entire area of the base layer, wherein the insulating intermediate layer encloses and projects past pixel areas made of the organic electroluminescence layer and arranged to form a matrix, and wherein the top electrode applied on top of each pixel area extends partially across the adjacent lattice wall.
