Patent number: 6720769Abstract: A detecting method and detector expands the capabilities of Nuclear Magnetic Resonance (NMR) analysis. A Rotational Exchange Gradient Imager (REGI) allows for real-time, in situ investigation of materials subjected to the effects of centrifugal force by NMR analysis. The REGI comprises a cylindrical stator formed of an electrically conductive, non-magnetic material, a rotor contained in the cylindrical stator formed of an electrically non-conductive, non-magnetic material, and a conductor located along a central axis of the cylindrical stator. A sample is contained within the rotor. The stator and central conductor serve to generate the RF magnetic field for NMR analysis. The rotor containing the sample is rotated within a stable air bearing formed between the cylindrical stator and rotor.Type: GrantFiled: June 21, 2002Date of Patent: April 13, 2004Assignee: The University of ChicagoInventors: Rex E.

Patent number: 6674283Abstract: Imaging apparatus are used in a toroid cavity detector for nuclear magnetic resonance (NMR) analysis to hold samples relative to a principal detector element which is a flat metal conductor, the plane of which is parallel to the longitudinal axis of the toroid cavity. A sample is held adjacent to or in contact with the principal detector element so that the sample can be subjected to NMR analysis when a static main homogeneous magnetic field (B0) produced by a NMR magnetic device is applied to the toroid cavity and an RF excitation signal pulse is supplied from a potentiostat to the principal detector element so that an alternately energized and de-energized magnetic field (B1) is produced in the sample and through the toroid cavity.Type: GrantFiled: September 20, 2002Date of Patent: January 6, 2004Assignee: The University of ChicagoInventors: Rex E.

Patent number: 6538444Abstract: A two dimensional B1-gradient NMR imager and methods for non-invasive spectroscopic investigations and imaging of the internal distribution and speciation of materials of fluid, solid, and semisolid objects in two spatial dimensions utilizing a toroid cavity detector. An RF signal transmitter/receiver generates a magnetic field B1 within the toroid cavity and receives a sample response to the magnetic fields B0 and B1. A pivot angle position controller adjusts a pivot angle position of the toroid cavity and enclosed sample to vary an angle between the magnetic field B0 and the central axis of said toroid cavity. A positional rotation controller positions the toroid cavity and enclosed sample at variable angular orientations relative to an initial position and a plane formed by the externally applied static main magnetic field B0 and the central axis of the toroid cavity. A computer sequentially receives and processes sample responses to produce a two-dimensional image.Type: GrantFiled: May 28, 2002Date of Patent: March 25, 2003Assignee: The University of ChicagoInventors: Rex E.

Patent number: 6191583Abstract: A toroid cavity detector includes an outer cylindrical housing through which extends a wire along the central axis of the cylindrical housing from a closed bottom portion to the closed top end of the cylindrical housing. In order to analyze a sample placed in the housing, the housing is placed in an externally applied static main homogeneous magnetic field (B0). An RF current pulse is supplied through the wire such that an alternately energized and de-energized magnetic field (B1) is produced in the toroid cavity which B1 field is oriented perpendicular to the B0 field. Following the RF current pulse, the response of the sample to the applied B0 field is detected and analyzed. In order to minimize the detrimental effect of probe ringing, the cylindrically shaped housing is elongated sufficiently in length so that the top and bottom portions are located in weaker, fringe areas of the static main magnetic B0 field.Type: GrantFiled: July 26, 1999Date of Patent: February 20, 2001Assignee: The University of ChicagoInventors: Rex E.

Patent number: 5574370Abstract: A toroid cavity detection system for determining the spectral properties and distance from a fixed point for a sample using Nuclear Magnetic Resonance. The detection system consists of a toroid with a central conductor oriented along the main axis of the toroidal cylinder and perpendicular to a static uniform magnetic field oriented along the main axis of the toroid. An rf signal is inputted to the central conductor to produce a magnetic field perpendicular to the central axis of the toroid and whose field strength varies as the inverse of the radius of the toroid. The toroid cavity detection system can be used to encapsulate a sample, or the detection system can be perforated to allow a sample to flow into the detection device or to place the samples in specified sample tubes. The central conductor can also be coated to determine the spectral property of the coating and the coating thickness.Type: GrantFiled: September 2, 1994Date of Patent: November 12, 1996Assignee: The United States of America as represented by the United States Department of EnergyInventors: Klaus Woelk, Jerome W.

Patent number: 4476334Abstract: Ethanol is selectively produced from the reaction of methanol with carbon monoxide and hydrogen in the presence of a transition metal carbonyl catalyst. Methanol serves as a solvent and may be accompanied by a less volatile co-solvent. The solution includes the transition metal carbonyl catalysts and a basic metal salt such as an alkali metal or alkaline earth metal formate, carbonate or bicarbonate. A gas containing a high carbon monoxide to hydrogen ratio, as is present in a typical gasifer product, is contacted with the solution for the preferential production of ethanol with minimal water as a byproduct. Fractionation of the reaction solution provides substantially pure ethanol product and allows return of the catalysts for reuse.Type: GrantFiled: May 26, 1983Date of Patent: October 9, 1984Assignee: The United States Department of EnergyInventors: Michael J.

Patent number: 4152248Abstract: Coal liquid having a dissolved transition metal, catalyst as a carbonyl complex such as Co.sub.2 (CO.sub.8) is hydrogenated with hydrogen gas or a hydrogen donor. A dissociating solvent contacts the coal liquid during hydrogenation to form an immiscible liquid mixture at a high carbon monoxide pressure. The dissociating solvent, e.g. ethylene glycol, is of moderate coordinating ability, while sufficiently polar to solvate the transition metal as a complex cation along with a transition metal, carbonyl anion in solution at a decreased carbon monoxide pressure. The carbon monoxide pressure is reduced and the liquids are separated to recover the hydrogenated coal liquid as product. The dissociating solvent with the catalyst in ionized form is recycled to the hydrogenation step at the elevated carbon monoxide pressure for reforming the catalyst complex within fresh coal liquid.Type: GrantFiled: May 2, 1978Date of Patent: May 1, 1979Assignee: The United States of America as represented by the United States Department of EnergyInventors: Harold M.
