Publication number: 20140147310Abstract: A submersible pumping system for downhole use in extracting fluids containing hydrocarbons from a well. In one embodiment, the pumping system comprises a rotary induction motor, a motor casing, one or more pump stages, and a cooling system. The rotary induction motor rotates a shaft about a longitudinal axis of rotation. The motor casing houses the rotary induction motor such that the rotary induction motor is held in fluid isolation from the fluid being extracted. The pump stages are attached to the shaft outside of the motor casing, and are configured to impart fluid being extracted from the well with an increased pressure. The cooling system is disposed at least partially within the motor casing, and transfers heat generated by operation of the rotary induction motor out of the motor casing.Type: ApplicationFiled: January 30, 2014Publication date: May 29, 2014Applicants: Los Alamos National Security, Chevron U.S.A., Inc.Inventors: Daniel Francis Alan Hunt, F. Coyne Prenger, Dallas D. Hill, Todd Andrew Jankowski

Patent number: 7646272Abstract: A freely oriented portable superconducting magnet is disclosed. Coolant is supplied to the superconducting magnet from a repository separate from the magnet, enabling portability of the magnet. A plurality of support assemblies structurally anchor and thermally isolate the magnet within a thermal shield. A plurality of support assemblies structurally anchor and thermally isolate the thermal shield within a vacuum vessel. The support assemblies restrain movement of the magnet resulting from energizing and cooldown, as well as from changes in orientation, enabling the magnet to be freely orientable.Type: GrantFiled: October 12, 2007Date of Patent: January 12, 2010Assignee: The United States of America as represented by the United States Department of EnergyInventors: Eric N. Schmierer, F. Coyne Prenger, Dallas D. Hill

Patent number: 7168480Abstract: The present invention is a crank-shaped heat pipe for cooling rotating machinery and a corresponding method of manufacture. The crank-shaped heat pipe comprises a sealed cylindrical tube with an enclosed inner wick structure. The crank-shaped heat pipe includes a condenser section, an adiabatic section, and an evaporator section. The crank-shape is defined by a first curve and a second curve existing in the evaporator section or the adiabatic section of the heat pipe. A working fluid within the heat pipe provides the heat transfer mechanism.Type: GrantFiled: April 29, 2004Date of Patent: January 30, 2007Assignee: Los Alamos National Security, LLCInventors: Todd A. Jankowski, F. Coyne Prenger, Joseph A. Waynert

Patent number: 7153435Abstract: A process for removing heavy metals from water is provided. The process includes the steps of introducing magnetite to a quantity of water containing heavy metal. The magnetite is mixed with the water such that at least a portion of, and preferably the majority of, the heavy metal in the water is bound to the magnetite. Once this occurs the magnetite and absorbed metal is removed from the water by application of a magnetic field. In most applications the process is achieved by flowing the water through a solid magnetized matrix, such as steel wool, such that the magnetite magnetically binds to the solid matrix. The magnetized matrix preferably has remnant magnetism, but may also be subject to an externally applied magnetic field. Once the magnetite and associated heavy metal is bound to the matrix, it can be removed and disposed of, such as by reverse water or air and water flow through the matrix.Type: GrantFiled: July 22, 2003Date of Patent: December 26, 2006Assignee: Los Alamos National Security, LLCInventors: F.

Patent number: 4702090Abstract: A magnetic refrigerator has a rotating magnetic wheel which includes a stack of spaced rings of magnetic material. Heat transfer plates of a high temperature heat extractor are interleaved with the magnetic rings and extend to a solid heat transfer conduit which leads to a high temperature terminal. Superconducting magnet coils are mounted to provide a magnetic field through the magnetic wheel at the position of the high temperature heat transfer plates. Low temperature extractor heat transfer plates are positioned outside of the magnetic field and interleave with the rings of the magnetic wheel to transfer heat thereto which is conducted from a low temperature terminal through a solid conduit.Type: GrantFiled: October 24, 1986Date of Patent: October 27, 1987Assignee: Astronautics Corporation of AmericaInventors: John A. Barclay, Walter F. Stewart, F. Coyne Prenger, Carl B. Zimm, John P. Parsons

Patent number: 4642994Abstract: A magnetic refrigerator operating in the 4 to 20 K range utilizes heat pipes to transfer heat to and from the magnetic material at the appropriate points during the material's movement. In one embodiment circular disks of magnetic material can be interleaved with the ends of the heat pipes. In another embodiment a mass of magnetic material reciprocatingly moves between the end of the heat pipe of pipes that transmits heat from the object of cooling to the magnetic material and the end of the heat pipe or pipes that transmits heat from the magnetic material to a heat sink.Type: GrantFiled: October 25, 1985Date of Patent: February 17, 1987Assignee: The United States of America as represented by the United States Department of EnergyInventors: John A.
