Appl. No.:

11/473906

Inventors:

Charles Beatty - Gainesville FL, US
Nathan Tortorella - Sheboygan WI, US

Assignee:

University of Florida Research Foundation - Gainesville FL

International Classification:

C08L 23/04

US Classification:

525240000

Abstract:

A polypropylene composition and a method to prepare the composition. The method includes the mixing and extrusion of an isotactic polypropylene, at least one impact modifying polymer, at least one primary co-agent that is a monofunctional monomer, at least one secondary co-agent which is a multifunctional monomer, oligomer, or polymer, and a radical initiator. The composition may be prepared in an extruder. The resulting composition has improved impact strength properties as compared to isotactic polypropylene and isotactic impact modifying polymer blends. The resulting composition may be used in a variety of forms such as extrusions, injection or blow-molded products, films, non-woven fabrics, or thermoformed products.

International Classification:

B05D 306
B05D 700

US Classification:

427 41

Abstract:

Closed system and process for the conversion of gaseous or vaporizable organic and/or organo-metallic compound to inert solid which is resistant to solvent extraction, and is itself essentially nontoxic or convertible through oxidation or other natural processes to a toxic material. This process involves a low temperature, low energy conversion in a close system, of an organic and/or organo-metallic material by initially fragmenting such material into its basic elements follow thereafter by randomly recombining such elements as a solid coating or deposit upon a substrate. In the preferred embodiments of this invention, the toxic and/or potentially toxic material is injected as a gaseous phase into a chamber where it is subjected to an RF energy source, thereby forming a plasma which is contained within the chamber by a magnetic field. The chamber, as well as, the other components of the conversion system are maintained under a negative pressure which allows for the transport of the plasma throughout the system to a second chamber where the elements of the plasma can recombine in a random fashion. The recombination of these elements as a solid allows for ease of handling and prevents their release into the atmosphere or ground water.

Larry Lee Wenning - Lakeland FL
Charles L. Beatty - Gainesville FL

Assignee:

Witt Plastics of Florida Inc. - Lakeland FL

International Classification:

B29C 5326

US Classification:

425296

Abstract:

A corrugated plastic panel is produced by providing a plastic panel corrugation device whereby a plastic material is extruded, a cooled extrusion is formed by passing the extrusion through a cooling roller assembly, a corrugated extrusion is formed by passing the cooled extrusion through a forming roller assembly when the cooled extrusion has reached its impressionable temperature range, a corrugated extrusion is passed through a pulling roller assembly when the corrugated extrusion has reached its hardening temperature range, and a corrugated plastic panel is formed by passing the corrugated extrusion through an extrusion cutting assembly.

International Classification:

G03G 514

US Classification:

430 59

Abstract:

This invention is directed to an improved photoresponsive device containing as a protectant overcoating a top layer of a crosslinked polyvinylsilicate resulting from the reaction of polysilicic acid with a polyvinyl alcohol having a number average molecular weight of from about 10,000 to about 100,000.

Assignee:

Xerox Corporation - Stamford CT

International Classification:

G03G 2100

US Classification:

355 15

Abstract:

A cleaning blade is provided for cleaning residual toner particles and other contaminants from an electrostatic imaging surface comprising a surface having rigid spherical protuberances adapted to be pressed against the imaging surface to form a seal between the blade and imaging surface which retards flow of particles between the blade and imaging surface.

Charles L. Beatty - Webster NY
Jean-Claude Pollet - Rochester NY

Assignee:

Xerox Corporation - Stamford CT

International Classification:

B29C 1700

US Classification:

264143

Abstract:

A process for preparing electrostatographic toner particles having improved mechanical properties and controlled particle size and size distribution is provided through molecular orientation of glassy, brittle, semicrystalline, low molecular weight polymers. Molecular orientation results in more flexible polymers and greatly increases their yield stress, modulus and mechanical fatigue lifetime. The molecular orientation of these polymers is obtained by extrusion of fibers or films thereof.

Abstract:

A delivery system for an agriculturally active chemical comprises a body or carrier portion including a first water dispersible agriculturally inert and essentially nontoxic composition containing a predetermined aliquot of the agriculturally active chemical. The body or carrier portion has a predetermined size and a predetermined shape. The delivery system also comprises a protective coating, about the body portion, of a second water dispersible agriculturally inert and essentially nontoxic composition. The aliquot of the agriculturally active chemical is an amount of the agriculturally active chemical effective to terminate functioning of a target agricultural pest upon application of the agriculturally active chemical to soil or water via the delivery system. The agriculturally active chemical can take the form of a biocide such as an insecticide, fungicide or nemacide. More particularly, the agriculturally active chemical is a compound taken from the group consisting of dimethoate, vydate, vendex, metasystox-R, fluvalinate and kethane, invermectin, propoxur, chlorpyrifos, diazinon, malathion, carbaryl, fenvalerate, methomyl, acephate, permethrins, and diflubenzuron.
