Abstract: During the course of fabricating a gas panel, a partially completed gas panel is placed in a vacuum oven for a bake-out, back fill and sealing operation. During the bake-out, the oven is evacuated to remove gaseous and vapors contaminants from the gas panel. Thereafter, during the back fill operation, a display gas atmosphere is admitted to the oven which fills the gas panel. Thereafter, the panel is sealed to lock in the desired display gas. The sealing is accomplished by providing a hole in the back panel in which is placed a plug so shaped as to allow the gas panel to be initially evacuated and thereafter back filled with gas. Once the panel is back filled, the plug is selectively melted to fill the hole and then allowed to solidify to complete the seal.

Abstract: During the construction of display gas panels front and back panels are connected together by means of a seal which forms a chamber for receiving a display gas. A hole is provided in the back plate which is outside the display viewing area and a glass tube is fitted into this hole and sealed to the assembly. The tube is used to first evacuate and then admit display gas into the chamber. An electric tip-off oven is used to collapse the tube stem to form a permanent seal. A cast protective heat sink and a reflective foil wafer are used to protect the gas panel and the tube-to-gas panel interface from damage by the oven.
