Abstract

An improved cryopump for the removal of gases from a high vacuum, comprising a cryopanel incorporating honeycomb structure, refrigerant means thermally connected to the cryopanel, and a rotatable channel moving azimuthally around an axis located near the center of the cryopanel, removing gases absorbed within the honeycomb structure by subliming them and conducting them outside the vacuum vessel.

Continuous cryopump with a method for removal of solidified gases

Patent Carlson, L. W.; Herman, H.

An improved cryopump for the removal of gases from a high vacuum, comprising a cryopanel incorporating honeycomb structure, refrigerant means thermally connected to the cryopanel, and a rotatable channel moving azimuthally around an axis located near the center of the cryopanel, removing gases adsorbed within the honeycomb structure by subliming them and conducting them outside the vacuum vessel. 4 figs.

Method and apparatus for continuous removal of carbon dioxide vapors from gases

Patent Baxter, Larry; Sayre, Aaron; Burt, Stephanie; ...

A method for continuously removing carbon dioxide vapor from a carrier gas is disclosed. This method includes, first, causing direct contact of the carrier gas with a liquid mixture in a separation chamber, the carrier gas condensing at a lower temperature than the carbon dioxide vapor. A combination of chemical effects cause the carbon dioxide to condense, complex, or both condense and complex with the liquid mixture. The liquid mixture is chosen from the group consisting of: first, a combination of components that can be maintained in a liquid phase at a temperature below the carbon dioxide vapor's condensation point,more »« less

Fluid clathrate system for continuous removal of heavy noble gases from mixtures of lighter gases

Patent Gross, Kenneth C [Bolingbrook, IL]; Markun, Francis [Joliet, IL]; Zawadzki, Mary T [South Bend, IN]

An apparatus and method for separation of heavy noble gas in a gas volume. An apparatus and method have been devised which includes a reservoir containing an oil exhibiting a clathrate effect for heavy noble gases with a reservoir input port and the reservoir is designed to enable the input gas volume to bubble through the oil with the heavy noble gas being absorbed by the oil exhibiting a clathrate effect. The gas having reduced amounts of heavy noble gas is output from the oil reservoir, and the oil having absorbed heavy noble gas can be treated by mechanical agitationmore »« less

Continuous cryopump with a device for regenerating the cryosurface

Patent Foster, Christopher A [Rte. 5, Box 101-B, Clinton, TN 37716]

A high throughput continuous cryopump is provided. The cryopump (10) incorporates an improved method for regenerating the cryopumping surface (22) while the pump is in continuous operation. The regeneration of the cryopumping surface (22) does not thermally cycle the pump, and to this end a small chamber (91) connected to a secondary pumping source (60) serves to contain and exhaust frost removed from the cryopumping surface (22) during such regeneration. The frost is exhausted at a rate substantially independent of the speed of the cryopump which enhances the capability of the pump to achieve a high compression ratio and allowmore »« less
