Appl. No.:

09/838463

Inventors:

Wadood Hamad - Mahwah NJ
Xiang Yu - Paramus NJ
Thomas D. Sandry - Tuxedo NY

Assignee:

International Paper Company - Stamford CT

International Classification:

D21F 706

US Classification:

162198, 162 49, 162253, 162DIG 6, 162DIG 11

Abstract:

A mathematical model is used to design paper and paperboard having improved runnability. The mathematical model provides an estimate of fracture toughness for an optimized paper product based on specific measurement parameters, e. g. , filler percent, softwood content and caliper for optimal fracture toughness. After the optimizing set of measurement parameters has been acquired, these parameters can be used to manufacture grades of paper having improved runnability performance, e. g. , in printing presses.

International Classification:

G03F 7/00
G03F 7/004

US Classification:

4302701, 430311

Abstract:

This invention relates to photochromic filaments composed of the lithium salt of a conjugated, polymerizable polyacetylene having a carboxylic acid or carboxylate terminal group wherein the length to width ratio of said filaments is between about 5000:1 and about 5:1 and the average length of the filament is up to about 5 cm. The invention also pertains to the use of said salts in maximized radiation sensitivity for imaging, radiation dose measurement or mapping and detection of radiation fields.

International Classification:

D04H001/00

US Classification:

428/297400

Abstract:

A method of preparing a composite material in which a dry mixture of a polymeric material and a fiber material is subjected to heating and pressure followed by cooling and reduction of pressure sufficient to melt the polymeric material and to maximize fiber material-polymeric material interactions, while minimizing fiber material-fiber material interactions. The resulting composite material has excellent strength.

US Classification:

430/030000, 430/270100

Abstract:

In accordance with this invention, there is provided a method of imaging, measuring and displaying a 3-dimensional dose distribution of an energy field in a translucent 3-dimensional object comprises: applying an energy field to the object such that the optical properties are changed upon receipt of the energy; optically scanning the object at various positions and angles to provide a series of 2-dimensional representations of the object; detecting the measuring light projection data indicative of optical changes in the object; calibrating the optical change in the object to the dose of the energy corresponding to each position scan; mapping the dose of the energy in the object and visually recording the summation of said 2-dimensional representations on an image display receiver comprising a radiation activated metal salt of a crystalline, thermochromic polyacetylene having a conjugated structure uniformly distributed in a rigid or high density semi-solid matrix by a color alteration due to polymerization of the activated polyacetylene to provide a permanent, 3-dimensional image of the object in high spatial resolution. The invention further provides image display receivers and radiation sensitive materials.
