Patent number: 10352617Abstract: A method and device for purifying a process gas mixture, such as a cryogen gas, in which impurity components of the mixture are removed by de-sublimation via cryo-condensation. The gas mixture is cooled to a temperature well below the condensation temperature of the impurities, by direct exchange of the gas mixture with a cooling source disposed in a first region of the device. The de-sublimated or frozen impurities collect about the cooling region surfaces, and ultimately transferred to a portion of the device defining an impurities storage region. The output-purified gas is transferred from the impurities storage region, is optionally passed through a first micrometer sized filter, through a counter-flow heat exchanger, and ultimately up to an output port at room temperature. A method of purging the collected impurities and regenerating the device is also disclosed.Type: GrantFiled: September 25, 2014Date of Patent: July 16, 2019Assignees: UNIVERSITY OF ZARAGOZA, QUANTUM DESIGN INTERNATIONAL, INC., CONSEJO SUPERIOR DE INVESTIGACIONES CIENTIFICASInventors: Conrado Rillo Millan, Jost Diederichs, Michael Bancroft Simmonds

Patent number: 10113793Abstract: A cryocooler-based gas scrubber, or cryocooler-based gas purifier, utilizes the cooling power of a cryocooler to cool and condense cryogen gas forming coalesced impurities which are then filtered through a filter matrix, such as for example a fiberglass filter matrix. The scrubber may further comprise a counter-flow heat exchanger for warming the purified gas prior to dispensing at an outlet for storage or consumption.Type: GrantFiled: July 8, 2013Date of Patent: October 30, 2018Assignee: QUANTUM DESIGN INTERNATIONAL, INC.Inventors: Michael Bancroft Simmonds, Jost Diederichs

Patent number: 9671159Abstract: A liquefier includes a Dewar having a storage portion and a neck portion extending therefrom. A hermetically isolated liquefaction chamber is disposed within the neck of the Dewar. One or more control components including a temperature and pressure sensor are coupled to a CPU and disposed within the liquefaction chamber for dynamic control of liquefaction conditions. A gas flow control is coupled to the CPU for regulating an input gas flow into the liquefaction chamber. A volume surrounding the liquefaction chamber may be adapted to provide a counter-flow heat exchange. These and other features provide improved liquefaction efficiency among other benefits.Type: GrantFiled: July 16, 2012Date of Patent: June 6, 2017Assignee: QUANTUM DESIGN INTERNATIONAL, INC.Inventors: Jost Diederichs, Ronald Sager

Patent number: 9310104Abstract: A modular architecture for helium compressors is described. In the modular architecture, oil is cooled independently from gas. In one aspect, the oil is cooled subsequent to the gas with a series of water-cooled heat exchangers. In another aspect, the oil is cooled using a water-cooled heat exchanger coupled to a radiator, and the gas is independently cooled using a refrigerant-cooled heat exchanger coupled to a condensing unit.Type: GrantFiled: August 7, 2013Date of Patent: April 12, 2016Assignee: Quantum Design International, Inc.Inventors: Jost Diederichs, Michael Bancroft Simmonds

Patent number: 9234691Abstract: A cryostat for providing temperature regulation, one purpose being measuring physical properties of materials, the cryostat employing a superconducting magnet assembly for generating variable magnetic field in the sample space and a cryogenic cooler for cooling the sample space. The cryogenic cooler chamber configuration provides for efficient heat exchange between different stages of the cryogenic cooler without the need for physical heat links. This construction enables selective delivery of cooling power from the cryogenic cooler to the desired areas within the cryostat without using flexible physical thermal links. A counter flow exchanger and ambient temperature valves facilitate efficient use of the cryogenic cooler stages. The removal of large heat load generated by the superconducting magnet while operating in the sweeping mode is achieved, in part, by employing a solid plate thermal coupling element between the cryogenic cooler chamber and the magnet assembly.Type: GrantFiled: March 11, 2010Date of Patent: January 12, 2016Assignee: Quantum Design International, Inc.Inventors: Randall Black, Dinesh Martien, William Neils, Jost Diederichs

Patent number: 8384504Abstract: A magnet system for generating a magnetic field may include a superconducting magnet, a switch, and a heater element thermally coupled to the switch. The superconducting magnet is structured to generate magnetic fields, and the switch includes a non-inductive superconducting current carrying path connected in parallel to the superconducting magnet. In general, the switch is structured to only carry a level of current that is a portion of the current required to obtain a full field by the superconducting magnet.Type: GrantFiled: January 6, 2006Date of Patent: February 26, 2013Assignee: Quantum Design International, Inc.Inventors: Jost Diederichs, Andreas Amann, Michael B.

Publication number: 20120167598Abstract: A multi-well helium Dewar is provided for recirculating coolant about a cryostat probe; the Dewar includes a first well containing a first coolant reservoir, and a second well containing a second coolant reservoir. A fluid connection extends between the first and second coolant reservoirs. A low impedance conduit further connects a top end of the second well to the first well. In this regard, the Dewar at least partially contains a cryocooler within the first well and a cryostat probe within the second well. Vibrational noise is reduced by the incorporation of soft mounting components for connecting various features. A thermal shield of the Dewar can be thermally connected to isolated components for additional cooling power and increased efficiency during initialization. A second fluid connection may include a valve attached to a counter-flow heat exchanger for efficiently re-condensing excess gas within the Dewar.Type: ApplicationFiled: September 25, 2011Publication date: July 5, 2012Applicant: QUANTUM DESIGN, INC.Inventors: Jost Diederichs, Michael Bancroft Simmonds
