Abstract
Abstract Improved through-the-seal electrical conductive means are provided for use in a cathode ray tube to effect multiple connections within the envelope structure. The conductive member being associated with the funnel-panel seal facilitates a bridging internal connection joining a discrete funnel related area with a related area on the panel wall.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
219 words
Improved electrical conductive means in a cathode ray tube structure whereof the envelope has a longitudinal axis therethrough and includes a face panel having a viewing portion and an encompassing sidewall therearound terminated by a perimetric sealing seat which is bonded by a fritted seal therealong to a compatible sealing seat terminating the wall of a related contiguous funnel portion of the envelopic integration, said electrical conductive means being a through-the-seal electrical conductive member comprising: a substantially U-shaped metallic transversal element formed of a longitudinal strip of electrical conductive material substantially configurated as a pseudo-horseshoe shaping having two opposed legs oriented in a common direction and joined by a planar bridging portion therebetween to effect straddleorientation and clamping engagement on a terminal wall portion of said envelope, the first of said legs being located adjacent to the internal surface of said envelope with the second of said legs being adjacent to the external surface thereof, the terminal ends of said legs being dimensioned apart and individually flared slightly outward to provide to provide sliding placement of said conductive element relative to one of said sealing seats and the related terminal wall thereof; and resilient contacting means attached to said first leg in a manner to effect internal pressured electrical connection with at least one conductive area within said envelope.
Claim 2
Dependent Claim
219 words
Improved electrical conductive means in a cathode ray tube structure whereof the envelope has a longitudinal axis therethrough and includes a face panel having a viewing portion and an encompassing sidewall therearound terminated by a perimetric sealing seat which is bonded by a fritted seal therealong to a compatible sealing seat terminating the wall of a related contiguous funnel portion of the envelopic integration, said electrical conductive means being a through-the-seal electrical conductive member comprising: a substantially U-shaped metallic transversal element formed of a longitudinal strip of electrical conductive material substantially configurated as a pseudo-horseshoe shaping having two opposed legs oriented in a common direction and joined by a planar bridging portion therebetween to effect straddleorientation and clamping engagement on a terminal wall portion of said envelope, the first of said legs being located adjacent to the internal surface of said envelope with the second of said legs being adjacent to the external surface thereof, the terminal ends of said legs being dimensioned apart and individually flared slightly outward to provide to provide sliding placement of said conductive element relative to one of said sealing seats and the related terminal wall thereof; and resilient contacting means attached to said first leg in a manner to effect internal pressured electrical connection with at least one conductive area within said envelope.
Claim 3
Dependent Claim
29 words
The improved electrical conductive means according to claim 1 wherein the bridging portion of said U-shaped conductive element is bondingly incorporated in a sandwiched manner through said fritted seal.
Claim 4
Dependent Claim
52 words
The improved electrical conductive means according to claim 1 wherein said resilient contacting means is in the form of a longitudinal projecting tongue-like contacting member extending substantially in the plane of said U-shaped conductive element in a related axial manner to effect internal pressured contact with the interior surface of said envelope.
Claim 5
Dependent Claim
90 words
The improved electrical conductive means according to claim 1 wherein said resilient contacting means is in the form of a longitudinal member having a mid-point from which two opposed resilient tongue-like contacting members are extended in opposite directions in substantially the plane of said U-shaped conductive element in a related axial manner to effect internal pressured contact with two separate areas of the interior surface of said envelope, said longitudinal member being attached to said first leg of said conductive element at a substantially mid-point related area of said member.
Claim 6
Dependent Claim
37 words
The improved electrical conductive means according to claim 1 wherein said U-shaped conductive element is oriented to straddle the panel sidewall with the bridging portion of said element being related to the sealing seat of said panel.
Claim 7
Dependent Claim
37 words
The improved electrical conductive means according to claim 1 wherein said U-shaped conductive element is oriented to straddle the funnel sidewall with the bridging portion of said element being related to the sealing seat of said funnel.
