Filed:

Jan 13, 2010

Appl. No.:

12/686619

Inventors:

Michael T. Combs - Shady Spring WV, US
Bruce Ray Woodson - Bluefield VA, US

International Classification:

C13K 13/00

US Classification:

127 37

Abstract:

A process for recycling cellulose acetate ester waste comprising the steps of: providing a reactor, adding cellulose acetate ester waste and a hydrolyzing agent to the reactor to create an agent/waste mixture followed by hydrolyzing the cellulose acetate ester waste by agitating and heating the agent/waste mixture for a period of time to create a hydrolyzed mixture. The hydrolyzing agent is then distilled and/or separated from the hydrolyzed mixture followed by separating and removing solid material from the hydrolyzed mixture to create a water soluble product stream which includes monosaccharides, polysaccharides, partially hydrolyzed cellulose, acetic acid, or combinations thereof. The water soluble product stream is then collected.

G06Q 10/00

US Classification:

705 3, 705 2, 715823, 709203

Abstract:

The activity notification process includes a first step of selecting an activity center on a home screen of a home station. The home screen of the home station has a plurality of selectable activity center choices, the selection thereof generating a plurality of selectable patient location options. The next step includes selecting one of the location options to send a message to an activity station of the activity center, the home station touch screen returning to its home screen with the activity center being predominantly highlighted thereon. The activity station generates an alert window providing directions to a location. The predominately highlighted activity center on the home station touch screen is deselected, only when the message has been answered, thereby returning the home screen thereon to a state that does not show the predominant highlights, the deselection providing verification that the message has been answered. The activity center may be disabled until the required activity is completed. The activity notification system is particularly adapted for use in a physician or dental office.

Appl. No.:

13/175503

Inventors:

Michael T. Combs - Shady Spring WV, US

Assignee:

ALLIANT TECHSYSTEMS, INC. - Minneapolis MN

International Classification:

G01N 7/00

US Classification:

73 1902, 73 1901

Abstract:

In at least one embodiment, the invention is directed to a method of determining the nitrogen content in nitrocellulose by High Performance Liquid Chromatography (HPLC). It is within the scope of the invention for the sample of nitrocellulose to be unstable nitrocellulose, unrefined nitrocellulose, or refined nitrocellulose. The sample of nitrocellulose can wet or dry. A sample of nitrocellulose that is wet can be in acid or in water. Before HPLC, the sample is dissolved in a suitable solvent. The nitrogen content of the sample is determined by comparing the retention time of the sample to a graph of retention time to amount of nitrogen due to the linear correlation of retention time and percent nitrogen substitution.

International Classification:

C08B 3/00
C08B 3/06

US Classification:

536 83, 536 63

Abstract:

Cellulose acetates and processes for producing same. The process involves esterifying a cellulose containing material in the presence of a densified gas such as supercritical carbon dioxide to form a cellulose acetate product having a degree of substitution less than 3. The cellulose acetate preferably is sulfate-free.

International Classification:

C02F 1/52

US Classification:

210725

Abstract:

The present invention is to a process for reducing and removing organic phosphorus acid from waste stream. The process involves adding a multivalent metal salt to the waste stream and adjusting the pH level of the waste stream to an optimum level to maximize the removal of organic phosphorus acid.

US Classification:

536 76, 536 69

Abstract:

Instilling an acidic catalyst to a reaction mixture can be beneficial during the acylation of cellulose. Methods described herein can comprise preparing a reaction mixture comprising an acylating agent and cellulose, instilling a catalyst comprising an acid to the reaction mixture, and reacting the cellulose with the acylating agent in the presence of the catalyst, thereby forming an acylated cellulose.

US Classification:

536 76, 536 69

Abstract:

Instilling an acidic catalyst to a reaction mixture can be beneficial during the acylation of cellulose. Methods described herein can comprise preparing a reaction mixture comprising an acylating agent and cellulose, instilling a catalyst comprising an acid to the reaction mixture at an overall catalyst loading level of about 1% or less by weight of the cellulose, and reacting the cellulose with the acylating agent in the presence of the catalyst, thereby forming an acylated cellulose.
