US Patent:

7198655, Apr 3, 2007

Filed:

May 3, 2004

Appl. No.:

10/837998

Inventors:

Robert F. Hogsett - Lakewood CO, US
Philippus J. Meyer - Secunda, ZA
Michael F. Ray - Canyon Lake TX, US
Michael L. Schlegel - Story WY, US
Sheldon L. Schultz - Boise ID, US

Assignee:

Evergreen Energy Inc. - Denver CO

International Classification:

C10L 9/00

US Classification:

44621, 44626

Abstract:

Carbonaceous materials are thermally upgraded in a pressurized steam environment to remove moisture and other byproducts. A variety of water/solid separation devices may be employed in a process vessel to maximize moisture removal from the upgraded charge. Heating media inlet nozzles and process chamber vents are strategically positioned at the process vessel wall to minimize short circuiting of heating media to vessel outlet vents and to continuously separate hot water removed from the charge and condensed steam, such that the upgraded material removed from the process vessel is not discharged with accompanying free moisture. After upgrading, the charge may be rehydrated to improve its stability during shipping and storage.

Filed:

Appl. No.:

13/084746

Inventors:

Marcus RAJCHEL - Arvada CO, US
Michael F. RAY - Spring Branch TX, US

International Classification:

G01N 33/44
C01C 3/10

US Classification:

436 85, 423371

Abstract:

Provided is a method for high concentration cation exchange metathesis of divalent ions such as calcium with univalent ions such as sodium or potassium. Due to the difference between ionic valences between the exchanged ions, the provided process behavior is strongly dependent upon the selection of resin properties and to total solution normality. A combination of resin properties and solution normality is provided to achieve the cation exchange.

Appl. No.:

6/191577

Inventors:

Dale C. Rudolph - Parker CO
Michael D. Ray - Decatur IL
Richard L. Hansher - Colorado Springs CO
Paul W. Daugherty - North Glen CO

Assignee:

Technicare Corporation - Solon OH

International Classification:

B25G 300

US Classification:

403 27

Abstract:

Disclosed is a system for identifying which one of a plurality of interchangeable transducer heads is connected with an ultrasonic scanner. The system includes a unique impedance mounted on each transducer head and an impedance determining circuit in the scanner for determining the impedance of the interconnected transducer head. The impedance determination circuit is connected to a character generator for producing an alpha-numeric representation of the transducer head designation along the margin of a cathode ray tube on which an ultrasonic image is displayed. Also disclosed is an improved resolver mounting in which a cylindrical axle is used as a pivot pin between two scan arms of the ultrasonic scanner. A potentiometer for resolving the angle between pivotally connected arms is mounted on one arm with its shaft resiliently connected with the axle for rotation with the axle and other scan arm.
