52079520, May 4, 1993

Filed:

Apr 2, 1991

Appl. No.:

7/682841

Inventors:

Anselm C. Griffin - Hattiesburg MS

Assignee:

University of Southern Mississippi - Hattiesburg MS

International Classification:

F21V 900
C09K 1952
C08G 6724

US Classification:

252582

Abstract:

Side chain liquid crystalline polymers which exhibit nonlinear optical responses, particularly second and third harmonic generation, are presented together with methods for making them. These polymers derive their nonlinear optical behavior from selective pendant groups that are attached via spacers to the backbone. Several embodiments having chiral structures are subject to efficient dipolar and molecular alignment by electric field poling. The methods disclosed for making these polymers are polycondensation, graft polymerization, and copolycondensation.

Assignee:

Minnesota Mining and Manufacturing Company - St. Paul MN

International Classification:

B32B 2736

US Classification:

428480

Abstract:

Partially fluorinated polymer comprising a backbone and side-chains, in which the backbone and side-chains are each 4 atoms long and are chemically incompatible, one chain being at least predominantly hydrocarbon and the other comprising a C. sub. 4+ perfluorocarbon moiety.

Filed:

Sep 1, 1976

Appl. No.:

5/719870

Inventors:

Gino J. Mangialardi - Greenville MS

Agriculture - Washington DC

International Classification:

G01R 2702

US Classification:

324 65P

Abstract:

A unique radial electrode has been designed in the same configuration as the feed roller of a cotton ginning system. The electrode is then installed as part of a feed roller and properly insulated from the ginning system. When seed cotton is fed between the feed rollers the charged radial electrode becomes a signal electrode communicating with the rest of the system which forms as a ground. The resultant current flow between the electrode and the ground passing through the seed cotton produces a measure of the moisture in the seed cotton.

Agriculture - Washington DC

International Classification:

D01B 900

US Classification:

19 66CC

Abstract:

an apparatus for conditioning seed cotton during the ginning operation is disclosed. Seed cotton which is to be conditioned to a proper moisture content is fed through a rotating vacuum seal dropper onto a series of moving belts located within a conditioning chamber. The moving belts are arranged to retain the seed cotton for a predetermined critical period within the chamber. Conditioned air is circulated through the chamber and brought into intimate contact with the seed cotton thereby properly adjusting the moisture content. The seed cotton is then vented through a rotating vacuum seal dropper into gin processing equipment.
