  • Publication number: 20050284297
    Abstract: The present invention provides a gas purification system with improved efficiency, simpler construction, cost reductions, form factor improvements, and increased durability. The present invention provides cost and form factor improvements through fewer components overall and through utilizing multiple integrated components. Prior art gas purification systems are more bulky and complicated. The present invention achieves increased thermal efficiency through utilization of a regenerative heat exchanger to recapture a portion of the heat energy transferred to the gas during the purification process. Prior art purifiers lacked a regenerative heat exchanger. The present invention integrates the two components into one integrated heater and purification vessel assembly. The present invention integrates the two discrete components into one integrated hydrogen sorption and particle filter assembly. The integrated hydrogen sorption and particle filter assembly is also capable of operating at higher temperatures.

  • Patent number: 4909271
    Abstract: In an ultrahigh purity sealed gas valve of the Y-type having a bellows located in a stem bore, a second seat is provided so that the seat seal engages the second seat to seal off the space within the bonnet tube and the bellows from communicating with the gas flow path, thereby preventing contaminating particles from the bellows from entering the gas system and also decreasing the dead space presented to the closed gas system by the valve. A purge port is located between the open and closed positions of the seat seal thereby permitting purging gas to bathe the sealing members and the bellows in both positions.
