  • Wearless valve for cryorefrigerator
    Publication number: 20070107442
    Abstract: An improved method of reducing wear dust and torque required to turn a multi-port rotary disc valve utilizes a thrust bearing to hold the valve seat and/or valve disc such that they are not in contact with each other, or have light contact each other.

  • Multi-stage pulse tube with matched temperature profiles
    Publication number: 20060174635
    Abstract: Convection losses associated with different temperature profiles in the pulse tubes and regenerators of multi-stage pulse tubes mounted in helium gas in the neck tube of a MRI cryostat are reduced by providing one or more of thermal bridges, and/or insulating sleeves between one or more pulse tubes and regenerators, and/or spacers, and spacer tubes, in one or more pulse tubes and regenerators.

  • Cryopump with two-stage pulse tube refrigerator
    Publication number: 20060026968
    Abstract: Disclosed is a two-stage pulse tube cryopump cooling system in which the pulse tubes and valves are inline, with the hot ends of the pulse tubes at the top and the valve mechanism is at the bottom and the hot ends and buffer volume are cooled by an inline coolant line from the compressor input to the compressor output and attached in heat exchange relationship with the buffer volume.

  • Enzymes
    Publication number: 20050191627
    Abstract: Various embodiments of the invention provide human enzymes (ENZM) and polynucleotides which identify and encode ENZM. Embodiments of the invention also provide expression vectors, host cells, antibodies, agonists, and antagonists. Other embodiments provide methods for diagnosing, treating, or preventing disorders associated with aberrant expression of ENZM.

  • Fast warm up pulse tube
    Publication number: 20050115247
    Abstract: This invention provides an improved means of quickly warming a pulse tube (165) by shifting the phase relation of flow to the warm end of the pulse tube relative to flow to the warm end (117) of the pulse tube relative to flow to the warm end of the regenerator (160) using a “four valve” concept and the “active buffer” concept. Several different pulse tube configurations and valve timing relations that are effective at reversing the cycle from the normal mode, which produces cooling at the pulse tube heat station, to a reverse mode that produces heating are disclosed.

  • Cryopump control system
    Publication number: 20050034465
    Abstract: A cryopump control system with single or multiple cryopumps is controlled by a parallel system operating modules connected by two low voltage wires. A separate cable is also connected to the operating module to provide power to various cryopump components. Communication is via a bus that communicates directly with IC devices in the operating modules that also contain small capacitors to enable the control system to be run by a single computer processor in which all of the logic for controlling one or more cryopumps and communicating with additional optional components resides.
