Patent number: 10465851Abstract: Embodiments provide systems and methods for taking power from an electric power grid and converting it into higher-pressure natural gas for temporary storage. After temporary storage, the higher-pressure natural gas may be expanded through an expansion engine to drive a generator that converts energy from the expanding natural gas into electrical power, which may then be returned to the electric power grid. In this way, the disclosed systems and methods may provide ways to temporarily store, and then return stored power from the electric power grid. Preferably, the components of the system are co-located at the same natural gas storage facility. This allows natural gas storage, electrical energy storage, and electrical energy generation to take place at the same facility.Type: GrantFiled: September 22, 2017Date of Patent: November 5, 2019Assignee: Northwest Natural Gas CompanyInventors: Sarah Sue Adams, Seyfettin Can Gulen, Roger Martin Haley, David Allen Weber, J.

Patent number: 9379604Abstract: Radio frequency (RF) switching circuitry includes support circuitry for maintaining one or more RF switching elements in either an ON or OFF state. The support circuitry includes a negative charge pump adapted to quickly generate a negative voltage during a “boost” mode of operation, and maintain the negative voltage during a normal mode of operation. The negative charge pump includes an oscillator adapted to generate a high frequency oscillating signal for driving the charge pump during the boost mode of operation and a low frequency oscillating signal for driving the charge pump during the normal mode of operation. By generating the high frequency oscillating signal only during a boost mode of operation, spurious noise coupled to the RF switch circuitry is minimized during a normal mode of operation.Type: GrantFiled: July 19, 2013Date of Patent: June 28, 2016Assignee: RF Micro Devices, Inc.Inventors: Jinhua Zhong, Daniel Charles Kerr, Kelvin Kai Tuan Yan, Brian Keith White

Patent number: 8950194Abstract: In order to minimize the loss of cryogen during transportation of superconductive magnet systems, or indeed at any time that the refrigerator is turned off, part of the boil-off gas is directed from the cryogen vessel through the refrigerator interface and past the refrigerator to cool the refrigerator. Some of the heat conducted along the refrigerator into the system is intercepted and removed by that part of the boil-off gas. The heat load onto the cryogenic vessel is thereby reduced, which in turn reduces the boil-off of cryogen from the cryogenic vessel. This part of the boil-off gas is then vented from the system along with the remainder of the boil-off gas, for example to leave the cryogenic liquid vessel via the access neck.Type: GrantFiled: May 12, 2005Date of Patent: February 10, 2015Assignee: Siemens PLCInventors: Timothy John Hughes, Stephen Paul Trowell, Keith White

Publication number: 20140138236Abstract: An atmospheric water generator and system for condensing and collecting moisture contained in the air serves to cool and dehumidify the air. One aspect of the design includes generation of electricity via a turbine configured to be actuated by an increase in gas pressure from heat transfer fluid in a continuous heat transfer fluid system as it exits the evaporator. In alternative embodiments, the system can be used in a multi-zone application or to provide cooled air and water to a building. An embodiment primarily for use as an air conditioning unit is also described. Alternatively, fly-back technology is used to configure solar or wind powered DC current for use by a water generation system. In certain environments oil free compressors are employed in the water generation unit.Type: ApplicationFiled: May 24, 2012Publication date: May 22, 2014Applicant: AWG INTERNATIONAL, INC.Inventor: Keith White

Patent number: 8650888Abstract: The present invention relates to a cryostat having a service neck for access to a superconducting magnet. In many cryogenic applications components, e.g. superconducting coils for magnetic resonance imaging (MRI), superconducting transformers, generators, electronics, are cooled by keeping them in contact with a volume of liquefied, the whole cryogenic assembly being known as a cryostat. In order to operate a superconducting magnet, it must be kept at a temperature below its superconducting transition temperature. A cryostat must provide access to the vessel containing the liquefied helium for the initial cooling of the magnet to its low operating temperature, for periodic refilling of systems where there is a loss of helium, and provide sufficient access whereby to enable operation and maintenance of the magnet.Type: GrantFiled: November 20, 2002Date of Patent: February 18, 2014Assignee: Siemens PlcInventors: Florian Steinmeyer, Keith White

Patent number: 7891196Abstract: A quench line and exit plenum configuration for a mobile MRI system housed in a transportable trailer includes an exit plenum with deflector plates that direct the quench flow of cold gases upward and away from surrounding objects. In addition, the plenum also includes dual vents to facilitate optimum gas flow and water drainage. The deflector plates are configured to utilize the Venturi effect to create an auxiliary flow of the ambient air to help deflect the flow of cold gases away from nearby pedestrians, when the magnet is quenching, and to enable service personnel to fill the magnet safely while in the vicinity of the exit plenum.Type: GrantFiled: July 14, 2005Date of Patent: February 22, 2011Assignee: Siemens PlcInventors: Stephen Paul Trowell, Keith White
