Filed:

Aug 28, 2003

Appl. No.:

10/651272

Inventors:

Timothy R. Fox - Chicago IL, US
David T. Nisius - Des Plaines IL, US
Michael T. Duncan - Elgin IL, US

Assignee:

Bio-Imaging Research, Inc. - Lincolnshire IL

International Classification:

H05G001/64

US Classification:

378 988, 25037011, 348294

Abstract:

A method and apparatus are provided for extending a dynamic range of an X-ray imaging system. The method includes the steps of detecting a plurality of X-ray beams, amplifying each of the plurality of detected X-ray beams using a first gain value, amplifying each of the plurality of detected X-ray beams using a second gain value, and forming an X-ray image from the detected X-ray beams amplified by the first gain value and from the detected X-ray beams amplified by the second gain value.

Appl. No.:

8/457521

Inventors:

Michael P. Duncan - Schererville IN

Assignee:

Ferro Corporation - Cleveland OH

International Classification:

C08F 832

US Classification:

525368

Abstract:

The present invention provides a new and improved process for preparing a polybutene amine composition comprising the steps of reacting a chlorinated polybutene with an excess of at least one mole of at least one type of an amine compound per mole of the chlorinated polybutene at a reaction temperature of at least about 100. degree. C. ; neutralizing the reaction mixture with calcium oxide; and recovering the polybutene amine composition, the recovery process including the steps of removing the formed water and the neutralized and excess of the amine compound and removing inorganic solids using a non-aqueous separation technique such as filtration. During the neutralization step, water formation is kept to a minimum and no water is intentionally added to the process thereby minimizing resultant waste streams and/or undesirable by-products.

Abstract:

Radiation scanning systems providing multiple views of an object in different planes and a reconstruction algorithm for reconstructing quasi-three-dimensional images from a limited number of views. A system may include bend magnets to direct accelerated charged particles to multiple targets in different viewing locations. Another system collimates radiation generated by a plurality of radiation sources into multiple beams for scanning an object at multiple angles. The object may be a cargo container, for example. The reconstruction algorithm uses an optimization algorithm and imaging and feasibility models to reconstruct quasi-three-dimensional images from the limited number of views.
