Appl. No.:

10/467964

Inventors:

David Yue - Baltimore MD, US
Michael Erickson - Baltimore MD, US

International Classification:

C12Q001/68
G01N033/53
G06F019/00
G01N033/48
G01N033/50

US Classification:

435/006000, 435/007100, 702/020000

Abstract:

The invention provides a method for determining a measure of FRET comprising obtaining sequential fluorescent intensity readings from a specimen, such as a cell using three filter cubes. Simple equations manipulate readings from each of the filter sets or cubes to specify a unitless index of FRET called the FRET ratio (FR). FR bears a linear relation to FRET efficiency E. The method also provides for determining the fraction of acceptor-tagged molecules bound by donor-tagged molecules; the relative affinity of binding; and the strength of FRET interactions when all acceptor-tagged molecules are bound by donor. The latter determination enables estimates of the physical distance and/or orientation between interacting fluorophore molecules. The method can be used to detect analytes or inter- or intramolecular interactions. In a preferred aspect, the method is used in an HTS assay to identify modulators of such interactions.

US Classification:

208 58

Abstract:

An improved catalyst handling process and system is provided to safely, effectively, and automatically transport catalyst by remote control to and from resid hydrotreating units. The process and equipment feature computerized monorail equipment for efficiently transporting special fresh catalyst containers and spent catalyst containers. Various electronic equipment is provided to electronically detect the type of catalyst stored in the catalyst containers. Lift elevators, four-prong liftfork trucks, remote control tilting mechanisms, catalyst transfer lines, deoiler units, bridge cranes, and other transport vehicles, as described, can also be used.

Appl. No.:

6/781921

Inventors:

Michael E. Erickson - Country Club Hills IL
Roman T. Plichta - Naperville IL

Assignee:

Amoco Corporation - Chicago IL

International Classification:

B65B 100

US Classification:

222 23

Abstract:

A specially arranged fresh catalyst container is provided to effectively and efficiently transport store, and dispense fresh catalyst into a resid hydrotreating unit in an oil refinery. The fresh catalyst container is equipped with monorail- and bridge crane- grab channels to receive and be carried by the grab hooks of a monorail, as well as by the grab hooks of an overhead bridge crane. The container also has separate forklift channels to accommodate movement of the container by a forklift truck onto railway cars and flatbed trucks for transport to and from the refinery. The container has special electronic and visual indicators for indicating the type of catalyst within the closed interior of the container.

International Classification:

US Classification:

294 6827

Abstract:

A special spent catalyst container is provided to safely and effectively transport, store, and dispense spent catalyst and residual reactor oil from a resid hydrotreating unit to a reclamation site or disposal area. In order to protect and safeguard the environment, the container is constructed of a catalytically resistant oil-impermeable steel with a special shape and arrangement to prevent spent catalyst and residual reactor oil from the resid hydrotreating unit from spilling, leaking, and accumulating on the nation's highways. The spent catalyst container has a rotatable truncated bin with a support frame to enhance the structural strength and integrity of the bin. The bin has monorail and bridge crane-receiving slots to alternatively receive the grab hooks of a monorail and a bridge crane to facilitate transport by both monorail and the bridge crane. The bin also has upper and lower forklift channels to receive rotatable tines of a forklift truck to accommodate power-driven inversion of the container in order to facilitate rapid discharge of the contents of the container.
