Publication number: 20030211970Abstract: Disclosed is a method for processing a plasmid-containing fluid comprising contacting the plasmid-containing fluid with two charged membranes and obtaining a plasmid-enriched fluid such as a purified plasmid. In an embodiment, the first charged membrane is positively charged, and the second charged membranes is positively or negatively charged membrane. In a preferred embodiment, both first and second charged membranes are positively charged. In another embodiment, the plasmid-containing fluid is contacted with two positively charged membranes and a third charged membrane. The present invention further provides a system and a kit for processing plasmid-containing fluids.Type: ApplicationFiled: November 19, 2002Publication date: November 13, 2003Inventors: Samuel Nochumson, Yujing Yang, Joe L.

Patent number: 5913238Abstract: A method of decreasing the bulge of gable top cartons by evaluating and modifying top sealing heat patterns. Cartons are formed, dye stained and the quality of the seal evaluated for heat damage and top seal quality. The heating pattern is adjusted as required, and the resulting heat seal is reevaluated to determine if further adjustments are required, so that the resulting cartons can achieve a near air-tight condition in the headspace of the carton to thereby resist bulging.Type: GrantFiled: May 16, 1997Date of Patent: June 15, 1999Assignee: International Paper CompanyInventors: Robert L. Lanham, Joe L. Kinsey, Jr., Charles E. Gibbons

Patent number: 5728249Abstract: A method of forming a non-foil barrier laminate structure which can be made into a container using radio-frequency heat-sealing techniques. The structure incorporates radio-frequency sealable ethyl acrylates which, in combination with additional thermoplastic material layers, produce a structure that can be formed, filled and sealed into cartons on commercially available form-fill-seal-machinery fitted with a radio frequency generator and sealing tool.Type: GrantFiled: July 3, 1995Date of Patent: March 17, 1998Assignee: International Paper CompanyInventors: Joe L. Kinsey, Jr., Mari Asanuma

Patent number: 5693373Abstract: A method of improving heat-seals for polyolefin polymers which are coated onto a paperboard substrate. The method obviates the need for use of a curable bonding agent. The materials are exposed to high energy radiation prior to formation of the heat seal to induce crosslinking of the poller and thereby increase the average molecular weight of same.Type: GrantFiled: July 26, 1996Date of Patent: December 2, 1997Assignee: International Paper CompanyInventor: Joe L. Kinsey, Jr.

Patent number: 5587204Abstract: The specification discloses a multilaminar paperboard composite having improved recyclability and methods for forming and recycling the paperboard composite. The paperboard composite comprises a paperboard substrate having two surfaces, a highly alcoholized polyvinyl alcohol binder layer adjacent at least one surface of the paperboard substrate and a polyethylene polymeric layer bound to the polyvinyl alcohol layer. The highly alcoholized polyvinyl alcohol layer is present in an amount of from about 2 to about 12 pounds per 3000 square feet of substrate.Type: GrantFiled: March 22, 1995Date of Patent: December 24, 1996Assignee: International Paper CompanyInventors: Joe L. Kinsey, Jr., Robert L. Lanham, Jr.

Patent number: 5196269Abstract: The present invention relates to a novel coextrusion coating for paper or paperboard substrates. The coextrusion includes a nonpolar polymer layer and a thin exterior skin layer made up of a nonpolar polymer and a polar copolymer. The addition of the polar polymer improves long term treatment level retention which improves long term wettability for printing and gluing adhesion during package or carton formation.Type: GrantFiled: November 22, 1991Date of Patent: March 23, 1993Assignee: International Paper CompanyInventors: James M. Kittrell, Charles F. Gibbons, Allan A. Whillock, Joe L. Kinsey, Jr., Cynthia L. Tanner

Patent number: 5002833Abstract: A dual ovenable paperboard based structure which contains a food contact resin layer. The resin layer in direct contact with the ovenable food product exhibits superior food release properties, grease and oil resistance, and resistance to warpage even after extended periods of time following oven heating. The unique laminate is formed via coextrusion coating techniques on conventional coextrusion equipment at conventional temperatures. The resulting product has a high degree of adhesion between the paperboard and the polymethylpentene food contact layer, and is capable of being utilized for forming pressed or locked corner food trays which can be subjected to oven cooking temperatures.Type: GrantFiled: April 4, 1990Date of Patent: March 26, 1991Assignee: International Paper CompanyInventors: Joe L. Kinsey, Jr., Charles E. Gibbons, James M. Kittrell

Patent number: 4806399Abstract: The present invention relates to an improved container for citrus juices and other liquids. The container utilizes a paperboard barrier laminate for the containment of essential oils and flavors. Also disclosed is a process of making the laminate. The laminate makes use of a layer of a heat-sealable polycarbonate polymer food contact layer to enhance the barrier properties of the laminate.Type: GrantFiled: May 29, 1987Date of Patent: February 21, 1989Assignee: International Paper CompanyInventors: Charles E. Gibbons, Joe L. Kinsey, Jr., Allan A. Whillock

Patent number: 4768376Abstract: A method and an apparatus for testing the adhesion between the polyethylene coating and paperboard stock of polyethylene coated paperboard stock, such stock typically used in forming milk and fruit juice cartons. A normally open ended pressure chamber is closed by clamping a piece of polyethylene coated paperboard over its open end. The coating facing the pressure chamber is cut completely through to form an opening. Air of a predetermined value is introduced into the pressure chamber. The opposite coating will form a bubble, indicating delamination, if the integrity of the adhesion between the polyethylene coating and the paperboard is poor. The air pressure at which delamination occurs is then used to quantify adhesion.Type: GrantFiled: June 17, 1987Date of Patent: September 6, 1988Assignee: International Paper CompanyInventors: Robert L. Lanham, Jr., William F. Muller, Kenneth E. Paulhamus, Joe L. Kinsey, Jr.
