Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
123 words
A method of producing a glass substrate with electrical conductors deposited thereon suitable for gas panel fabrication which comprises drawing a vitreous or crystallizing solder glass consisting essentially of, on a weight basis, 72% PbO, 15% B 2 O 3 , 4% SiO 2 , 5% Al 2 O 3 and 4% ZnO and having a softening point of 811° F into at least one rod 3 - 40 mils in diameter, applying said rod to one surface of said substrate adjacent the periphery thereof, and pre-firing said substrate for a period of time and at a temperature sufficient to permanently attach the solder glass thereto in a highly sintered or glassy state which will reflow and seal at a predetermined sealing temperature.
Claim 2
Independent Claim
123 words

Claim 3
Independent Claim
125 words
A method of producing a glass substrate with electrical conductors deposited thereon suitable for gas panel fabrication which comprises drawing a vitreous or crystallizing solder glass consisting essentially of, on a weight basis, 72% PbO, 15% B 2 O 3 , 2% SiO 2 , 5% Al 2 O 3 , and 6% ZnO and having a softening point of 800 ° F into at least one rod 3 - 40 mils in diameter, applying said rod to one surface of said substrate adjacent the periphery thereof, and pre-firing said substrate for a period of time and at a temperature sufficient to permanently attach the solder glass thereto in a highly sintered or glassy state which will reflow and seal at a predetermined sealing temperature.
Claim 4
Independent Claim
125 words
A method of producing a glass substrate with electrical conductors deposited thereon suitable for gas panel fabrication which comprises drawing a vitreous or crystallizing solder glass consisting essentially of, on a weight basis, 72% PbO, 15% B 2 O 3 , 2% SiO 2 , 5% Al 2 O 3 , and 6% ZnO and having a softening point of 800 ° F into at least one rod 3 - 40 mils in diameter, applying said rod to one surface of said substrate adjacent the periphery thereof, and pre-firing said substrate for a period of time and at a temperature sufficient to permanently attach the solder glass thereto in a highly sintered or glassy state which will reflow and seal at a predetermined sealing temperature.
Claim 5
Independent Claim
121 words
A method of producing a glass substrate with electrical conductors deposited thereon suitable for gas panel fabrication which comprises drawing a vitreous or crystallizing solder glass consisting essentially of, on a weight basis, 71% PbO, 19% B 2 O 3 , 2% SiO 2 , 15.9% ZnO, and 1.1% SnO 2 and having a softening point of 400° F into at least one rod 3 - 40 mils in diameter, applying said rod to one surface of said substrate adjacent the periphery thereof, and pre-firing said substrate for a period of time and at a temperature sufficient to permanently attach the solder glass thereto in a highly sintered or glassy state which will reflow and seal at a predetermined sealing temperature.
Claim 6
Independent Claim
121 words
A method of producing a glass substrate with electrical conductors deposited thereon suitable for gas panel fabrication which comprises drawing a vitreous or crystallizing solder glass consisting essentially of, on a weight basis, 71% PbO, 19% B 2 O 3 , 2% SiO 2 , 15.9% ZnO, and 1.1% SnO 2 and having a softening point of 400° F into at least one rod 3 - 40 mils in diameter, applying said rod to one surface of said substrate adjacent the periphery thereof, and pre-firing said substrate for a period of time and at a temperature sufficient to permanently attach the solder glass thereto in a highly sintered or glassy state which will reflow and seal at a predetermined sealing temperature.
