  • Method for facilitating catalyzed oxidation reactions, device for facilitating catalyzed oxidation reactions
    Patent number: 7091386
    Abstract: A catalytic process for the oxidation of organic. Oxygen is loaded into a metal foil by heating the foil while in contact with an oxygen-containing fluid. After cooling the oxygen-activated foil to room temperature, oxygen diffuses through the foil and oxidizes reactants exposed to the other side of the foil.
    Type: Grant
    Filed: May 3, 2004
    Date of Patent: August 15, 2006
    Assignee: U.S. Department of Energy
    Inventors: Robert J. Beuhler, Michael G. White, Jan Hrbek
  • Process to accomplish autothermal or steam reforming via a reciprocating compression device
    Patent number: 6793910
    Abstract: The invention provides a method and apparatus for producing a synthesis gas from a variety of hydrocarbons. The apparatus (device) consists of a semi-batch, non-constant volume reactor to generate a synthesis gas. While the apparatus feeds mixtures of air, steam, and hydrocarbons into a cylinder where work is performed on the fluid by a piston to adiabatically raise its temperature without heat transfer from an external source.
    Type: Grant

    Date of Patent: September 21, 2004
    Inventors: K. David Lyons, Robert James, David A. Berry, Todd Gardner
  • Fatty acyl-CoA reductase
    Patent number: 6143538
    Abstract: A bacterial gene which encodes an enzyme that is an acyl-CoA reductase. The acyl-CoA reductase is able to chemically reduce acyl-CoAs to their corresponding alcohols, via aldehyde intermediates.
    Type: Grant

    Date of Patent: November 7, 2000
    Assignee: The United States of America as represented by the United States Department of Energy
    Inventors: Chris R. Somerville, Steven E. Reiser
  • Simplified configuration for the combustor of an oil burner using a low pressure, high flow air-atomizing nozzle
    Patent number: 6102687
    Abstract: The invention relates to clean burning of fuel oil with air. More specifically, to a fuel burning combustion head using a low-pressure, high air flow atomizing nozzle so that there will be a complete combustion oil resulting in a minimum emission of pollutants. The inventors have devised a fuel burner that uses a low pressure air atomizing nozzle. The improved fuel burner does not result in the use of additional compressors or the introduction of pressurized gases downstream, nor does it require a complex design.
    Type: Grant
    Filed: September 28, 1998
    Date of Patent: August 15, 2000
    Assignee: U.S. Department of Energy
    Inventors: Thomas A. Butcher, Yusuf Celebi, Leonard Fisher
  • Method for detecting and diagnosing disease caused by pathological protein aggregation
    Patent number: 6063636
    Abstract: A method is provided for detecting pathological macromolecules in a patient, comprising obtaining body fluid from the patient, pretreating the body fluid, subjecting the pretreated body fluid to size-exclusion chromatography to create an excluded fluid, and analyzing the excluded fluid to detect macromolecules having a predetermined molecular weight. The method also allows for comparing elution spectra with reference spectra of suspect pathologic proteins.
    Type: Grant
    Filed: January 19, 1996

    Assignees: The United States of America as represented by the United States Department of Energy, The University of Tennessee
    Inventors: Fred J. Stevens, Elizabeth A. Myatt, Alan Solomon
  • Sampling device with a capped body and detachable handle
    Patent number: 6021681
    Abstract: The apparatus is a sampling device having a pad for sample collection, a body which supports the pad, a detachable handle connected to the body and a cap which encloses and retains the pad and body to protect the integrity of the sample.
