US Patent:

6404502, Jun 11, 2002

Filed:

Dec 29, 2000

Appl. No.:

09/752641

Inventors:

John G. Preston - Los Altos CA
Edward Belotserkovsky - San Francisco CA

Assignee:

Honeywell-Measurex Corporation - Morristown NJ

International Classification:

G01N 2157

US Classification:

356445

Abstract:

A single gloss sensor which can perform both DIN gloss measurement and DIN high gloss measurement, using the same hardware, and with minimal delay between the two measurements. The gloss sensor functions by directing light beams from a source to two different positions, either concurrently, or sequentially, between a position which measures gloss (75. degree) and a position which measures high gloss (45. degree). The gloss sensor also provides a reference light beam for correction of errors caused by the window glass, such as by dirt buildup.

International Classification:

G01L 504

US Classification:

73159

Abstract:

An apparatus and method for obtaining fiber weight measurements in the wet end of a sheetmaking system and for verifying fiber weight measurements taken in the wet end of a sheetmaking system which includes a water weight sensor positioned beneath the wire in the wet end of the sheetmaking system for obtaining water weight measurements and load cells residing beneath the water weight sensor for weighing the wet end sensor and the wire with wetstock (total weight) and without wetstock (tare weight). In one embodiment, the water weight measurement and the tare weight measurement are subtracted from the total weight to obtain the fiber weight in the wetstock. In another embodiment, the water weight measurement is used to obtain an predicted fiber weight measurement and the determined fiber weight is used to verify the predicted fiber weight measurement and the accuracy of the water weight measurement device.
