Abstract: A rotogravure printing medium includes a member coated with a film that is selectively removable to produce ink retaining cells. The film is formed by a series of adjacent strip of bead portions of a self-leveling, curable plastic composition which is engravable after curing. The adjacent strip or bead portions merge and self-level after deposition to produce a uniform continuous coating of the plastic composition.

Abstract: This invention provides making a rotogravure printing medium which includes a member coated with a film that is selectively removable to produce ink-retaining cells. A series of adjacent strip or bead portions of a self leveling, curable plastic composition which is engraveable after curing is provided on the surface of the member. The adjacent strip or bead portions merge and self level at and after deposition to produce a uniform, continuous coating of the plastic composition.

Abstract: A printing medium or image carrier for application to a printing apparatus or substrate which comprises a plastic composition which is applied to a printing substrate to form a plastic coating covering the substrate, which plastic coating is engraved to provide a printing medium. Preferred plastic compositions are those including epoxide resins such as cycloaliphatic epoxide resins, reaction products of epichlorohydrin and bisphenol A, bisphenol A epoxy resins modified with cresol novolac(s), epoxy-novolac resins, and epoxy-novolac based vinyl esters. The present invention provides for an effective rotogravure printing medium without the use and/or disposal of hazardous chemicals.

Abstract: A male contact assembly for high voltage switching applications includes a male contact with an electrically insulative member arranged concentrically with the contact and extending longitudinally therefrom. The insulative member has a hollow interior adjacent the contact and electrically conductive material in such hollow interior is in electrically conductive connection with the contact. Arc-quenching material overlies the insulative member and, on fracturing of such material, the insulative member isolates the electrically conductive material therein and the contact from electrical arcing.

The insulative member has a hollow interior adjacent the contact and a solid electrically conductive element in such hollow interior is in electrically conductive connection with the contact. Arc-quenching material overlies the insulative member and, on fracturing of such material, the insulative member isolates the electrically conductive member therein and the contact from electrical arcing.
