Appl. No.:

09/418909

Inventors:

Richard A. Jewell - Bellevue WA
Joseph Lincoln Komen - Bothell WA

Bing Su - Federal Way WA

Assignee:

Weyerhaeuser Company - Federal Way WA

International Classification:

D21H 1120

US Classification:

162 9, 1621576, 8181, 81161, 811551

Abstract:

The invention is directed to a method of making carboxylated cellulose fibers whose fiber strength and degree of polymerization is not significantly sacrificed. The method involves the use of TEMPO (2,2,6,6-tetramethylpiperidinyloxy free radical) as a primary oxidant and a hypohalite salt as a secondary oxidant in an aqueous environment. Preferably the oxidized cellulose is then stabilized against D. P. loss in alkaline environments and color reversion with a reducing agent such as sodium borohydride. Alternatively it may be treated with an oxidant such as sodium chlorite. The method results in a high percentage of carboxyl groups located at the fiber surface. The product is especially useful as a papermaking fiber where it contributes strength and has a higher attraction for cationic additives. The product is also useful as an additive to recycled fiber to increase strength. The method can be used to improve properties of either virgin or recycled fiber.

Abstract:

The invention is directed to a method of making carboxylated cellulose fibers whose fiber strength and degree of polymerization is not significantly sacrificed. The method involves the use of cyclic nitroxide free radical compounds as a primary oxidant and a hypohalite salt as a secondary oxidant in an aqueous environment. Preferably the oxidized cellulose is then stabilized against D. P. loss in alkaline environments and color reversion with a reducing agent such as sodium borohydride. Alternatively it may be treated with an oxidant such as sodium chlorite. The method results in a high percentage of carboxyl groups located at the fiber surface.

US Classification:

604/374000, 604/372000, 604/378000

Abstract:

An absorbent composite having a reticulated core and a fibrous stratum is disclosed. The core and stratum are integrally formed, and the stratum is coextensive with a surface of the core. In one embodiment, the composite includes strata on opposing surfaces of the core. The core includes a fibrous matrix and absorbent material. The fibrous matrix defines voids and passages between the voids, which are distributed throughout the composite. Absorbent material is located within some of the voids. On wetting, absorbent material located in these voids is expandable into the void. Methods for forming the composite and absorbent articles that include the composite are also disclosed.

International Classification:

G06F 17/30

US Classification:

707756

Abstract:

Provided is a method for processing input data in a storage system and in communication with a repository. Views are generated that comprise a tree of nodes selected from a subset of nodes in a hierarchical representation of a schema. The views are saved to the repository. At least one of the views are used to create a job comprising a sequence of data transformation steps to transform the input data described by input schemas to the output data described by output schemas.

International Classification:

G06Q 10/06

Abstract:

A performance monitoring system associated with a machine is provided. The system includes a sensor assembly configured to generate data of one or more parameters associated with an operation of the machine. The system further includes a controller communicably coupled to the sensor assembly. The controller is configured to determine a list of performance parameters associated with a performance of an operator while operating the machine. The controller selects a set of performance parameters from the list of performance parameters. The controller receives the data associated with the set of performance parameters from the sensor assembly. The controller compares the data associated with the set of performance parameters with respective predetermined thresholds. The controller evaluates the performance of the operator based on the comparison. Also, the controller displays a visual cue to the operator. The visual cue is indicative of the performance of the operator based on the evaluation.

International Classification:

G06F 17/30

US Classification:

707804

Abstract:

According to one embodiment of the present invention, a system decomposes a set of schema files. The system receives a set of schema files and automatically identifies a plurality of root schema files in the set, where a root schema file is determined based on remaining schema files in the set lacking a reference to that schema file. For each root schema file, the system creates a subset of the original set of schema files. The subset contains the root schema file, and at least one subset further includes one or more schema files that provide information for that root schema file. Embodiments of the present invention further include a method and computer program product for decomposing a set of schema files in substantially the same manners described above.
