Abstract
Abstract A gas discharge panel of which one or both panel plates are provided with cavities in the bottoms of which a conductor extends, which cavities and conductors are pressed in the softened material of the panel plate by means of a pressure plate in which cores in the form of balls or rods are secured, which cores comprise in the free end a groove in which the conductors are provided, which conductors remain behind in the panel plate after impression.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
203 words
A method of manufacturing a gas discharge panel for the display of pictures, the discharge panel including an upper panel plate and a lower panel plate, each plate havIng a number of mutually insulated parallel strip-shaped conductors, the conductors of the lower panel plate intersecting the conductors of the upper panel plate at an angle, and also including a gas atmosphere which is provided between the panels, said method comprising the steps of: immovably securing a plurality of cores in parallel rows in a pressure plate, said cores projecting beyond the surface of the plate; providing a groove in the free end of each core, said grooves being oriented in the same direction in each row and being parallel to grooves in other rows; placing strip-shaped conductors in each row of grooves in said cores; softening the upper plate of the discharge panel, said upper plate consisting of light-pervious insulating material; forcing the pressure plate with said strip-shaped conductors into said softened upper plate to deposit said strip-shaped conductors into said upper plate and to create cavities in said upper plate by said cores; and separating said pressure plate from the upper panel plate, the conductors and cavities remaining in the upper plate.
Claim 2
Independent Claim
203 words
A method of manufacturing a gas discharge panel for the display of pictures, the discharge panel including an upper panel plate and a lower panel plate, each plate havIng a number of mutually insulated parallel strip-shaped conductors, the conductors of the lower panel plate intersecting the conductors of the upper panel plate at an angle, and also including a gas atmosphere which is provided between the panels, said method comprising the steps of: immovably securing a plurality of cores in parallel rows in a pressure plate, said cores projecting beyond the surface of the plate; providing a groove in the free end of each core, said grooves being oriented in the same direction in each row and being parallel to grooves in other rows; placing strip-shaped conductors in each row of grooves in said cores; softening the upper plate of the discharge panel, said upper plate consisting of light-pervious insulating material; forcing the pressure plate with said strip-shaped conductors into said softened upper plate to deposit said strip-shaped conductors into said upper plate and to create cavities in said upper plate by said cores; and separating said pressure plate from the upper panel plate, the conductors and cavities remaining in the upper plate.
Claim 3
Dependent Claim
55 words
The method of claim 1 also including the steps of: making parallel channels in a second lower plate of the discharge panel, said lower plate consisting of an insulating material; inserting strip-shaped conductors in said channels; and lowering the surface of each of the strips to be below the surface of said second lower plate.
Claim 4
Dependent Claim
58 words
The method of claim 2 also including the steps of: placing the upper plate on the lower plate with said upper plate strips at an angle to said lower plate strips, said lowered strips of said lower plate forming channels which communicate with said cavities of said upper plate; and sealing the upper and lower panel plates together.
Claim 5
Dependent Claim
28 words
The method of claim 1 wherein the strip-shaped conductors are provided with projections which extend from the upper plate after separation, into the cavities formed by the cores.
Claim 6
Dependent Claim
39 words
A method as claimed in claim 1 wherein the cores consist of balls, and the method includes the steps of insetting the balls in the pressure plate to approximately half of their diameter and securing them in said plate.
Claim 7
Dependent Claim
34 words
A method as claimed in claim 1 wherein the cores consist of cylinders, and the method includes the steps of partly insetting the cylinders in the pressure plate and securing them in said plate.
Claim 8
Dependent Claim
20 words
A method as claimed in claim 1, including the step of providing luminescent material on the walls of the cavities.
