Patent number: 5424417Abstract: The invention relates to the prehydrolysis of lignocellulose by passing an acidic or alkaline solution through solid lignocellulosic particles with removal of soluble components as they are formed. The technique permits a less severe combination of pH, temperature and time than conventional prehydrolysis. Furthermore, greater extraction of both hemicellulose and lignin occurs simultaneously in the same reactor and under the same conditions.Type: GrantFiled: September 24, 1993Date of Patent: June 13, 1995Assignee: Midwest Research InstituteInventors: Robert W. Torget, Kiran L. Kadam, Teh-An Hsu, George P. Philippidis, Charles E. Wyman

Patent number: 5416198Abstract: A polycationic system for the removal of polyanions from a fluid medium is formed by, first, activating a biocompatible hydroxylated support with an organic sulfonyl chloride, such as p-toluene-sulfonyl chloride, in the presence of a dialkylamino pyridine activation catalyst, such as 4-dimethylamino-pyridine (DMAP). The activated support is then reacted with a polymer having a polyamide backbone with pendent alkyl amine groups, such as poly-L-lysine (PLL), to form C--N bonds between an activated carbon from the hydroxylated polymer and an amine group from the polymeric polyamide. Finally, any unreacted activated sites on the hydroxylated polymer are capped or removed with an effective amount of capping agent such as a mercapto (--SH), hydroxy (--OH) or amino (--NH.sub.2) containing compound which reacts with the unreacted activated sites. The pendent alkyl amines on the polyamide backbone exist, at the appropriate pH, as polycations.Type: GrantFiled: February 5, 1993Date of Patent: May 16, 1995Assignee: Research Medical, Inc.Inventors: Christopher G. Anderson, James C. McRea

Patent number: 5403921Abstract: An exercise regimen which enhances exercise endurance and performance. The regimen includes pre-exercise hydration with a glycerol solution combined with hydration during exercise with a glycerol based solution to prolong hydration effects. The first pre-exercise glycerol solution regimen begins 2 hours prior to exercise and ends 1/2 hour before exercise begins. The hydration during exercise regimen combines glycerol with a carbohydrate and sodium to prolong fluid retention.Type: GrantFiled: April 30, 1993Date of Patent: April 4, 1995Assignee: University of New MexicoInventors: Paul Montner, Thomas W.
