20090243723 | DIFFERENTIAL AND SYMMETRICAL CURRENT SOURCE - A controlled, symmetrical, stable current source that can power floating resistive loads, eliminates the need to connect the load directly to either a power supply or ground and protects the load against overpower should either or both sides of the load be shorted to ground. The current source includes two operational amplifiers for providing a current through the load that is proportional to an input voltage applied across the respective non-inverting inputs of the two operational amplifiers; two current sensing resistors for providing voltage drops that are proportional to the current through the load; and four summing resistors connected to the sensing resistors for providing to the inverting inputs of the operational amplifiers voltages that offset the sum of the voltage drops provided by the sensing resistors so that the current through the load is controlled by only the input voltage. | 10-01-2009 |

20100001821 | SUPERCONDUCTING QUICK SWITCH - 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. | 01-07-2010 |
20140338880 | Low Vibration Cryocooled System for Low Temperature Microscopy and Spectroscopy Applications - A vertical support rigidly mounted to a planar base positions and supports a cryocooler expander unit off axis and away from a sample to be examined. The sample support is likewise rigidly mounted to the planar base with a rigidly mounted sample housing therein. The cryocooler expander unit is suspended in the vertical support by spring dampening bearings. A pair of opposing flexible vacuum bellows connects the cryocooler expander unit to the sample housing and vertical support. This configuration isolates the sample from vibration. Flexible thermal links associated with a predictive electronic closed loop control sequence maintains sample temperature. | 11-20-2014 |

20120167598 | VACUUM ISOLATED MULTI-WELL ZERO LOSS HELIUM DEWAR - 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. | 07-05-2012 |

20140090404 | CRYOCOOLER-BASED GAS SCRUBBER - 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. | 04-03-2014 |
20160091245 | APPARATUS AND METHOD FOR PURIFYING GASES AND METHOD OF REGENERATING THE SAME - 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. | 03-31-2016 |

20120117984 | VALVE ASSEMBLY ADAPTED FOR DYNAMIC CONTROL OF GAS-FLOW ABOUT A CRYOGENIC REGION - A valve assembly is provided for dynamically controlling the inlet and exhaust of refrigeration gas between a cryocooler coldhead and a remote compressor. The valve assembly is optimized to minimize friction, power consumption, and wear while providing complete flexibility as to the timing, duration, and amplitude of its inlet and exhaust actions. The valve assembly comprises two separate open-close sections for the inlet and exhaust functions. These are mounted along a single rod, the position of which is controlled by a linear motor. The two sections are configured so that only one is open at each the rod's travel and neither is open at the midpoint of travel. A microprocessor and appropriate drive circuits precisely control the position of the rod as a function of time, and of displacer position when used with a Gifford-McMahon (G-M) cooler. | 05-17-2012 |

20140254624 | ULTRASENSITIVE RATIOMETRIC CAPACITANCE DILATOMETER AND RELATED METHODS - An ultrasensitive ratiometric capacitance dilatometer and related methods are described. The dilatometer provides a capacitance measurement based on a ratiometric capacitance, or the capacitance ratio measured between two or more parallel plate capacitors of the dilatometer. In this regard, an absolute capacity bridge is not required, and even more advantageously, the effects of adsorbed gas are greatly reduced compared to conventional dilatometers. The ratiometric capacitance dilatometer provides a symmetrical configuration, which reduces the effects of temperature gradients. Moreover, certain embodiments provide a “v-groove design”, wherein a first parallel plate capacitor forms an angle with a second parallel plate capacitor of the dilatometer along a key centerline of the dilatometer cell, which improves manufacturability due to simpler grinding, metalizing and assembly. | 09-11-2014 |
