Us Patents

Cryopump With Differential Pumping Capability
view source
US Patent:

52110222, May 18, 1993
Filed:

May 17, 1991
Appl. No.:

7/702597
Inventors:

Allen J. Bartlett - Milford MA
Douglas F. Aitken - Bedford NH
Assignee:

Helix Technology Corporation - Mansfield MA
International Classification:

B01D 800
US Classification:

62 555
Abstract:

A cryopump is capable of pumping a process chamber at a process pressure and differentially pumping a second chamber such as an RGA independently at a substantially lower pressure. A member extends through the cryopump housing into a low pressure region disposed within the second stage array. The member comprises a port for accessing the low pressure region, thus providing an independent differential pumping source. No physical seal is required between the member and the main cryopump volume to maintain the pressure differential.

US Patent:

52612449, Nov 16, 1993
Filed:

May 21, 1992
Appl. No.:

7/886721
Inventors:

Philip A. Lessard - Boxboro MA
Douglas F. Aitken - Bedford NH
Robert D. Bradford - Mansfield MA
Roland P. Graham - Wakefield MA
Steven A. Michaud - Hayerhill MA
Karen J. Manning - East Bridgewater MA
Assignee:

Helix Technology Corporation - Mansfield MA
International Classification:

B01D 800
US Classification:

62 555
Abstract:

A cold trap includes a set of baffles cooled by the cold finger of a closed cycle refrigerator. The baffles are vertically disposed in a vertical fluid conduit with frustoconical and conical surfaces for directing liquid to a circular trough during regeneration. After the liquid is collected, it is blown from the trough through a pressure relief valve by a nitrogen purge. The trough is formed in the upper surface of a connecting flange at the lower end of the fluid conduit.
