Abstract
Abstract Methods of making complex glass panel structures having precision dimensions. Glass tubes, rods, plates or other large glass structures are redrawn individually or in groups to filamentary or capillary size tube or gas continuums which are assembled as a monolayer to form a gas discharge panel, for example. Complex glass structures having precision uniform cross-sectional dimensions are constructed. Various novel glass structures and/or conductor configurations and methods of assembling are disclosed.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
180 words
In a gaseous discharge information display/memory panel in which an ionizable gaseous medium associated with a pair of transversely related conductor arrays is excited at least at one selected site thereof by applied electrical potentials between at least one conductor in one of said arrays and at least one conductor in the other of said arrays, the gas adjacent the crossing point of each pair of said conductors locating a selected site in the gaseous medium, respectively, and said arrays and conductors being electrically insulated from one another and the gaseous medium, the improvement wherein each conductor in the conductor array on the viewer's side of said panel is a single conductor physically offset to one side of the respective gas sites in the gaseous medium located thereby so as to not block light emission from the sites so located in the direction of a viewer of information displayed in said panel, and wherein said gaseous medium is confined in an elongated capillary tube and said at least one conductor is parallel to the longitudinal axis of said capillary tube.
Claim 2
Dependent Claim
180 words
In a gaseous discharge information display/memory panel in which an ionizable gaseous medium associated with a pair of transversely related conductor arrays is excited at least at one selected site thereof by applied electrical potentials between at least one conductor in one of said arrays and at least one conductor in the other of said arrays, the gas adjacent the crossing point of each pair of said conductors locating a selected site in the gaseous medium, respectively, and said arrays and conductors being electrically insulated from one another and the gaseous medium, the improvement wherein each conductor in the conductor array on the viewer's side of said panel is a single conductor physically offset to one side of the respective gas sites in the gaseous medium located thereby so as to not block light emission from the sites so located in the direction of a viewer of information displayed in said panel, and wherein said gaseous medium is confined in an elongated capillary tube and said at least one conductor is parallel to the longitudinal axis of said capillary tube.
Claim 3
Dependent Claim
32 words
The invention defined in claim 1 including a longitudinal member juxtaposed adjacent to said elongated capillary tube and forming a notch therewith, said at least one conductor being positioned in said notch.
