8268048, Sep 18, 2012

Filed:

Oct 14, 2009

Appl. No.:

12/578907

Inventors:

Bala Subramaniam - Lawrence KS, US
Andrew S. Borovik - Irvine CA, US
Chad A. Johnson - Longview TX, US

Assignee:

University of Kansas - Lawrence KS

International Classification:

B01D 53/04

US Classification:

95138, 25218828

Abstract:

Solid nanoparticulate transition metal complexes of Co(II) salen exhibit reversible oxygen absorption in a near stoichiometric manner. In contrast, no measurable oxygen binding was observed with unprocessed Co(II) salen.

Appl. No.:

11/449125

Inventors:

Bala Subramaniam - Lawrence KS, US
Andrew Borovik - Lawrence KS, US
Chad Johnson - Lawrence KS, US
Sarika Sharma - Olathe KS, US

International Classification:

A61K 9/14
B29B 9/00

US Classification:

424489000, 264005000, 977906000

Abstract:

Nanoparticulate metal complexes, such as those involving ruthenium, iron, cobalt, and nickel salens, are formed using precipitation with compressed antisolvent technology. The nanoparticle morphology may be altered by altering the planarity of molecular structure of the metal complex starting material.

Appl. No.:

17/982590

Inventors:

- Aurora NE, US
Chad E. Johnson - Aurora NE, US
Zane ZENTS - Omaha NE, US

Assignee:

Grain Weevil Corporation - Aurora NE

International Classification:

B25J 9/16
B65D 88/08
B65D 88/66
B25J 13/00
B25J 13/08

Abstract:

A piled grain surface management robot comprises an auger-based drive system, a memory, and a processor coupled with the memory. The processor is configured to control movement of the robot via the auger-based drive system. The processor is also configured to direct a traversal of a surface of piled grain in a bulk store, wherein a crust layer of the surface is broken up by auger rotation of the auger-based drive system during the traversal.

Assignee:

Grain Weevil Corporation - Aurora NE

International Classification:

G01B 5/20
G05D 1/00
G01K 3/14
B62D 57/04

Abstract:

A robot comprises an auger-based drive system, a memory, and a processor coupled with the memory and configured to control movement of the robot relative to a piled granular material in a bulk store, via the auger-based drive system, such that the robot traverses a first surface of the piled granular material in a mapping pattern. The processor is further configured to record a plurality of three-dimensional locations of the robot during the traversal in the mapping pattern. The processor or a computer system coupled with the processor is configured to assemble the plurality of three-dimensional locations of the robot into a three-dimensional surface map of the first surface of the piled granular material.

Assignee:

Grain Weevil Corporation - Aurora NE

International Classification:

B65D 88/68
B25J 9/16
G05D 1/02
B65D 88/08

Abstract:

A robot comprises an auger-based drive system, a memory, and a processor coupled with the memory and configured to control movement of the robot via the auger-based drive system. The processor obtains a first measurement of an angle of slope of a portion of piled granular material in a bulk store. In response to the first measurement satisfying a first condition, the robot traverses the portion of piled granular material to incite sediment gravity flow in the portion of piled granular material by disruption of viscosity of the portion of piled granular material through agitation of the portion of piled granular material by auger rotation of the auger-based drive system. The processor obtains a second measurement of the angle of slope of the portion of piled granular material. In response to the second measurement satisfying a second condition, the robot ceases traversal of the portion of piled granular material.
