Abstract: A printer for digital printing in which conductive ink is deposited in metered amounts on a substrate. The printer includes a wheel rotatable by a shaft of a motor, an idler disposed in a paint reservoir, and a segment of wire disposed around the wheel and the idler. A computer controls movement of the wire by controlling the rotation of the wheel. As the motor rotates the wheel, conductive ink contained within the paint reservoir coats the wire and is drawn by the wire in front of an air stream, which pulls the conductive ink from the wire and carries it toward the substrate. The digital printing of conductive ink can be used to form conductive patterns, such as circuit elements, on the substrate.

Abstract: Described is a process for producing a microstructured composite article including the steps of: providing a tool with a molding surface that is suitable for forming a microstructure; applying to at least a portion of the molding surface a plurality of lines of a flowable, curable resin composition; contacting the resin composition with a substrate; curing the resin composition; and, transferring the resin composition to the substrate. Alternative embodiments include heating the molding surface or resin composition, or both, to aid in the flow of the resin composition. The advantage of this process is that is that the microstructured composite articles are able to be produced at high speed and are free of air bubbles.

Abstract: The present invention is a screen, such as is used in back-lit projection screens, having a Fresnel lens laminated to another layer for support. The screen includes a Fresnel lens having an output surface, and a dispersing screen supportingly attached on a first side to the output surface of the Fresnel lens.
