Abstract
Abstract An anvil having a uniquely configurable support surface is provided for use in the manufacture of a face panel for a tension mask color cathode ray tube. The anvil is uniquely configurable for the panel and provides for contacting and conformably supporting the panel and preserving its intrinsic contour against gravitational deflection or other loading.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
137 words
For use in the manufacture of a tension mask color cathode ray tube having a face panel with a viewing side and a screening side, an apparatus for conformably supporting said face panel during the printing of said screening side by screen-printing apparatus, comprising: an anvil having a uniquely configurable support structure comprising a plurality of z-axis-adjustable supports for contacting and inflexibly supporting said viewing side of said face panel; means for positioning said screening side of said face panel, as supported by said anvil, into printing relationship with said screen-printing apparatus; such that the intrinsic contour of said face panel is preserved against gravitational or other loading incidental to the screen-printing operation; and means for moving the screening side of said face panel into contact with means for registering said face panel with said screen-printing apparatus.
Claim 2
Dependent Claim
137 words
For use in the manufacture of a tension mask color cathode ray tube having a face panel with a viewing side and a screening side, an apparatus for conformably supporting said face panel during the printing of said screening side by screen-printing apparatus, comprising: an anvil having a uniquely configurable support structure comprising a plurality of z-axis-adjustable supports for contacting and inflexibly supporting said viewing side of said face panel; means for positioning said screening side of said face panel, as supported by said anvil, into printing relationship with said screen-printing apparatus; such that the intrinsic contour of said face panel is preserved against gravitational or other loading incidental to the screen-printing operation; and means for moving the screening side of said face panel into contact with means for registering said face panel with said screen-printing apparatus.
Claim 3
Dependent Claim
21 words
The apparatus according to claim 1 wherein said z-axis adjustable supports comprise a plurality of z-axis-oriented pins movable and positionally fixable.
Claim 4
Dependent Claim
24 words
The anvil according to claim 1 including means for positioning said screening side of said face panel into printing relationship with a screen-printing apparatus.
Claim 5
Dependent Claim
112 words
For use in the manufacture of a tension mask color cathode ray tube having a face panel with a viewing side and a screening side, a process for conformably supporting said face panel during a screen-printing operation, comprising: providing an anvil having a uniquely configurable support structure, with a plurality of z-axis-oriented pins movable and positionally fixable extending therefrom; positioning said pins into near pressureless contact with said viewing side of said face panel; inflexibly supporting said face panel by immovably fixing said pins; printing said screen on said screening side; such that the intrinsic contour of said face panel is preserved against gravitational or other loading incidental to said screen-printing operation.
Claim 6
Dependent Claim
112 words
For use in the manufacture of a tension mask color cathode ray tube having a face panel with a viewing side and a screening side, a process for conformably supporting said face panel during a screen-printing operation, comprising: providing an anvil having a uniquely configurable support structure, with a plurality of z-axis-oriented pins movable and positionally fixable extending therefrom; positioning said pins into near pressureless contact with said viewing side of said face panel; inflexibly supporting said face panel by immovably fixing said pins; printing said screen on said screening side; such that the intrinsic contour of said face panel is preserved against gravitational or other loading incidental to said screen-printing operation.
Claim 7
Dependent Claim
132 words
For use in the manufacture of a tension mask color cathode ray tube having a face panel with a viewing side and a screening side, a process for conformably supporting said face panel during a screen-printing operation, comprising: providing an anvil having a uniquely configurable support structure with a plurality of pins extending therefrom normal to said panel, said pins being movable and positionally fixable; positioning said pins into near pressureless contact with said viewing side of said face panel; moving said pins to bring said screening side of said face panel into printing relationship with screen-printing apparatus; inflexibly supporting said face panel on said anvil by immovably fixing said pins; such that the intrinsic contour of said face panel is preserved against gravitational or other loading incidental to the screen-printing operation.
Claim 8
Dependent Claim
132 words
For use in the manufacture of a tension mask color cathode ray tube having a face panel with a viewing side and a screening side, a process for conformably supporting said face panel during a screen-printing operation, comprising: providing an anvil having a uniquely configurable support structure with a plurality of pins extending therefrom normal to said panel, said pins being movable and positionally fixable; positioning said pins into near pressureless contact with said viewing side of said face panel; moving said pins to bring said screening side of said face panel into printing relationship with screen-printing apparatus; inflexibly supporting said face panel on said anvil by immovably fixing said pins; such that the intrinsic contour of said face panel is preserved against gravitational or other loading incidental to the screen-printing operation.
