Abstract

1408374 Producing gas discharge display panels INTERNATIONAL BUSINESS MACHINES CORP 12 Feb 1974 [16 April 1973] 06258/74 Heading C1M In the production of gas discharge display devices a front panel 10 is secured to a back panel 11 provided with a tapered hole 20, a hollow plug 21 is pressed in the hole 20, the interior of the device 17 is filled with display gas by passing it through the hollow centre of the plug, and the plug melted using an electrical heater 22 to form a seal 21<SP>1</SP> for the hole 20. The panel is preferably formed of a glass having the weight per cent composition 72À78 SiO 2 , 0À484 Fe 2 O 3 ; 0À16 Al 2 O 3 ; 0À013 TiO 2 ; 8À63 CaO; 3À94 MgO; 13À86 Ha 2 O, 0À26 SO 3 and a softening point of 729‹ C. The plug is of a softer glass than that of the panel, e.g. one having the weight per cent composition PbO 64À0; B 2 O 3 15À3; ZnO 14À9; CuO 3À0; SiO 2 1À5; Bi 2 O 3 1À3 and a softening point of 419‹ C.
