  • Automated neon tube evacuation and gas filling system and process
    Patent number: 5352143
    Abstract: A system and method for automatically evacuating and filling neon tubing is disclosed wherein an electrical controller is provided to automatically control the evacuation and fill cycles. For this purpose, pneumatic actuator valves are utilized in the manifold system to selectively control the flow functions in the process during the evacuation and fill cycles. A bombarder signal is delivered to a bombarder unit by the controller, which generates electrical current through the electrodes of the tubing being processed to heat the tubing. A pressure gauge is placed in the manifold system to sense tube pressure and generate an electrical pressure signal which is transmitted to the electronic controller. A temperature sensor is placed in temperature sensing relation with the tubing to sense the temperature of the tubing and generate an electrical temperature signal also transmitted to the controller.
