Abstract
Abstract A static eliminator is fabricated by stamping a chain of linked equally spaced electrically conductive elements from sheet metal stock, each element including a projecting point; placing the chain of linked elements in longitudinally coextensive, dielectrically spaced relationship with a ribbon cable capable of carrying high voltage levels; constraining the chain and the cable to that placement while severing the links between elements so that each element is separated from the adjacent elements but retains the same spacing relative thereto and also retains the same spacing relative to the cable; and encapsulating the cable and the elements in that constrained configuration in a rigid mass of electrically insulative material from which the points of the elements project in equally spaced array.

Claim 1
Independent Claim
358 words
A method of producing a static eliminator, comprising stamping from sheet metal stock a unitary strip consisting of a plurality of electrically conductive elements joined together in a common plane along a common longitudinal axis by a plurality of links, said elements being of equal length in the direction parallel to said longitudinal axis and having a first side edge and a second side edge with each of the side edges being aligned along a respective line parallel to said longitudinal axis, each of said conductive elements including a respective coplanar projection point each extending transversely from said first side edge from a location intermediate the longitudinally spaced ends of said element, the projecting points of said elements being equally spaced from each other, and the corners of each element being directly connected to the corners of an adjacent element by one of said links at each corner, said links being spaced transversely from said elements beyond said first side edge and longitudinally spaced from adjacent said projecting points, juxtaposing said unitary strip and a substantially longitudinally coextensive ribbon conductor in dielectRically spaced parallel planes, integrally molding said juxtaposed dielectrically spaced unitary strip and ribbon conductor together in an electrically insulative block with said links and so that said projecting points and said intermediate link portions on each side extend from said block, severing a major portion of each of said links on a first side along a line spaced outwardly from said first side edge and intermediate said first side edge and a line interconnecting the apexes of said projecting points, and severing a major portion of each of the links along a line spaced outwardly from said second side edge to open the conductive paths between said elements while leaving said projecting points exposed in a substantially equally spaced array and, integrally encapsulating the electrically insulative block on the sides and edges with the links severed therefrom in a larger electrically insulative integrally molded block conforming in shape to the requirements of the environment in which said static eliminator is to be used and exposing the tips of said projecting points in said equally spaced array.
Claim 2
Independent Claim
358 words
A method of producing a static eliminator, comprising stamping from sheet metal stock a unitary strip consisting of a plurality of electrically conductive elements joined together in a common plane along a common longitudinal axis by a plurality of links, said elements being of equal length in the direction parallel to said longitudinal axis and having a first side edge and a second side edge with each of the side edges being aligned along a respective line parallel to said longitudinal axis, each of said conductive elements including a respective coplanar projection point each extending transversely from said first side edge from a location intermediate the longitudinally spaced ends of said element, the projecting points of said elements being equally spaced from each other, and the corners of each element being directly connected to the corners of an adjacent element by one of said links at each corner, said links being spaced transversely from said elements beyond said first side edge and longitudinally spaced from adjacent said projecting points, juxtaposing said unitary strip and a substantially longitudinally coextensive ribbon conductor in dielectRically spaced parallel planes, integrally molding said juxtaposed dielectrically spaced unitary strip and ribbon conductor together in an electrically insulative block with said links and so that said projecting points and said intermediate link portions on each side extend from said block, severing a major portion of each of said links on a first side along a line spaced outwardly from said first side edge and intermediate said first side edge and a line interconnecting the apexes of said projecting points, and severing a major portion of each of the links along a line spaced outwardly from said second side edge to open the conductive paths between said elements while leaving said projecting points exposed in a substantially equally spaced array and, integrally encapsulating the electrically insulative block on the sides and edges with the links severed therefrom in a larger electrically insulative integrally molded block conforming in shape to the requirements of the environment in which said static eliminator is to be used and exposing the tips of said projecting points in said equally spaced array.
Claim 3
Dependent Claim
234 words
A process for fabricating static eliminators intended to discharge static electricity from a sheet or web on which the static electricity is accumulated as an electrical charge, said process including forming a chain of electrically conductive elements each having a projecting point similarly located thereon and equally spaced from each other by two links directly joining each element to each adjacent element, each said link extending directly between corners of adjacent said elements and spaced from said projecting points, constraining said chain in dielectrically spaced relationship with an elongate flat high voltage cable so that the chain and the cable lie in substantially parallel planes and are substantially longitudinally coextensive, and severing said links to separate said elements while maintaining their constrained spaced relationship with said cable, wherein said dielectrically spaced relationship of said chain and said cable is achieved by inserting an elongate electrically insulative spacer bar therebetween, and wherein said constraining is achieved by encapsulating said cable, said spacer bar, and said chain except for said links and said projecting points, in a thin mass of integrally molded rigid electrically insulative material, and further including the step subsequent to said step of severing said links of enclosing said cable, said spacer bar, and said conductive elements in their constrained relationship in a larger mass of integrally molded rigid electrically insulative material with at least the tips of said projecting points remaining exposed.
Claim 4
Dependent Claim
