A track system may be configured to support drywall above a floor surface of a structure. The track system may be configured to comply with one or more building and/or material standards. The track system may comprise one or more components. A component may include a base section and a lateral section. The track system and/or components thereof may be configured such that they conform to a specified fire standard, including but not limited to ASTM E-119 one-hour and/or two-hour fire standards.

Track system

The present invention is direction to systems for assembling drywall tracks that support drywall above the floor.

Drywall track system

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.

Cryogenic waterpump

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.
