Thomas Michael Domin - Galena OH, US
Rodney Dale Maxson - Columbus OH, US
Dennis Charles Daugherty - Grove City OH, US
Steven Perry Sturm - Dublin OH, US
Assignee:

ABB Inc. - Columbus, Inc. OH
International Classification:

G01J005/02
US Classification:

25033907, 25033906, 2503381, 2503361, 2503391, 25033912, 250353, 250228, 356429
Abstract:

A single vane shutter flag is asynchronously controlled so that a measuring system light source is interrupted for a minimum necessary amount of time for standardization/calibration and normalization of InGaAs system detectors. Source/detector hemispheres or serially connected randomly oriented fiber bundles homogenize light passing to the detectors. Light source testing is performed by measuring spectral power distributions at a plurality of light source power levels and comparing the measurements to baseline characteristics established for the light source. Calibration sample life is extended indefinitely by controlling the shutter flag to block source light except for short calibration time periods during which standard light levels are provided.

US Patent:

7005639, Feb 28, 2006
Filed:

Jul 28, 2003
Appl. No.:

10/628197
Inventors:

Steven Perry Sturm - Dublin OH, US
Assignee:

ABB Inc. - Columbus OH
International Classification:

G01N 23/00
US Classification:

250308
Abstract:

Beta gauge composition correction is performed using signals from a plurality of detectors that are positioned so that the ratio of radiation received by the detectors depends on the composition of material through which the radiation passes before reaching the detectors. Radiation is measured at the detectors and the differences between radiation received by the detectors is used to compensate the beta gauge to correct for composition variations. An array of detectors is divided into inner detectors generally aligned with the central portion of a beta radiation beam and at least one set of outer detectors surrounding, at least in part, the inner detectors. Measurements are made including all the detectors, the inner detectors and the at least one set of outer detectors with the difference between the measurements made by the inner detectors and the outer detectors being used to compensate the total measurement made by all the detectors.

Filed:

Sep 24, 2009
Appl. No.:

12/566180
Inventors:

Steven P. Sturm - Dublin OH, US
Michael S. O'Hora - Dundalk, IE
Rodney D. Maxson - Supply VA, US
Assignee:

ABB, Ltd. - Dublin
International Classification:

G01N 21/86
US Classification:

25033907
Abstract:

Web measurement system monitors properties of a web during manufacture without chopping measuring radiation during web measurement. A single chop is performed at each sheet edge or every nsheet edge to measure edge temperature and edge thermal radiation for correction for Planckian radiation. Correction factors, including Planckian radiation correction factors, are derived for each point in a web profile. The measuring system also enables derivation of correction factors during operation in a single point and similar machine operating modes.

US Patent:

52331954, Aug 3, 1993
Filed:

Feb 25, 1992
Appl. No.:

7/841366
Inventors:

Ake A. Hellstrom - Columbus OH
Wim Muller - Westendorp, NL
Steven P. Sturm - Columbus OH
Alan M. Reid - Columbus OH
Assignee:

ABB Process Automation, Inc. - Columbus OH
International Classification:

G01N 2316
G21F 5015
US Classification:

2503601
Abstract:

Characteristics of moving webs are measured using a radiation source shutter which is rotatably movable between an opened-shutter position and a closed-shutter position and structured to permit access to the radiation source in the closed-shutter position. The source is configured to produce a fan-shaped radiation beam which passes through the web to a detector. The sizing of the fan-shaped beam and the detector together with the spacing the source and the detector are such that the beam width is substantially less than the detector while its length is greater than the detector. This novel beam shaping, detector arrangement provides composition insensitivity, increases solid beam angle and superior streak detection by aligning the beam length dimension with the direction of web movement. Alignment insensitivity is obtained by tuning the radiation beam using concentric rings or crossed strips of material which is semi-transparent to the radiation to compensate for geometric characteristics of the radiation source/beam and the detector. Air within an open portion of a measuring column extending between the radiation source and detector is conditioned and also used to condition electronics associated with the detector.

US Patent:

45825203, Apr 15, 1986
Filed:

Sep 10, 1984
Appl. No.:

6/648626
Inventors:

Steven P. Sturm - Columbus OH
Assignee:

Owens-Corning Fiberglas Corporation - Toledo OH
International Classification:

C03C 2502
G01J 100
US Classification:

65 343
Abstract:

The degree of cure of a traveling carbonaceous polymeric material (on 48), formed (at 34) from a plurality of chemical reactants (32) and subjected to a curing process (at 42 and 44) is determined by directing (with 86 and 88) into the traveling material radiations including a first infrared radiation (A1) from the group thereof adapted to selectively interact with molecular resonance vibrations at frequencies that are characteristic of respective terminal functional groups of atoms involved in reactions that take place in the material during the curing process. Also directed into the material is a second infrared radiation that is either of the kind (R) that does not exhibit substantial selective interaction with molecular resonance vibrations in the material or of the kind (A2) that is adapted to selectively interact with molecular resonance vibrations at a frequency that is characteristic of groups of atoms forming the backbones of the polymeric molecules in the material. Received (at 102) from the traveling material are radiations (148) that have interacted with the material. Produced (at 116, 118 and 122) from the received radiations are first and second responses to the first and second radiations.

Inventors:

Steven P. Sturm - Columbus OH
Assignee:

Process Automation Business, Inc. - Columbus OH
International Classification:

G01N 2135
US Classification:

250339
Abstract:

The printability of paper coated with kaolinite clay is dependent upon the flatness of kaolinite alumino-silicate clay platelets on the surface thereof. The flatness is determined by calculating the ratio of two infrared absorption bands from two specific types of structural hydroxyls characteristic of kaolinite clay platelet crystals.
