Publication number: 20030148268Abstract: The present invention identifies a new approach for antibiotic development. By identifying molecules in the cell wall of bacteria responsible for binding bacteriophage lytic enzymes, the present invention focuses on the pathways for possible antibiotic development. The pathway for the bacterial molecule is critical for bacterial survival and thus serves as a target for antibiotic identification.Type: ApplicationFiled: December 5, 2002Publication date: August 7, 2003Applicant: THE ROCKEFELLER UNIVERSITYInventors: Vincent A. Fischetti, Daniel C. Nelson, Jutta Loeffler

Patent number: 6596416Abstract: A decorative laminate is provided which includes one or more cellulosic core sheets, one or more decor sheets and optional overlay sheets. In one embodiment, one or more of the overlay sheets and/or decor sheets are impregnated prior to lamination with a mixture of a transparent resin and a photoluminescent material. As a result, the entire upper surface of the laminate visibly luminesces in the presence of exciting radiation. In another embodiment, an image or pattern is printed on one or more of the decor sheets with a ink including an organic photoluminescent material to provide an visibly luminescent image or pattern therein. It is envisioned that the invention could be used to provide a unique and appealing appearance when used as the surfacing for a wide variety of applications, including bowling lanes, game tables, counter-tops, dance floors, and signs such as “exit” signs.Type: GrantFiled: March 4, 2002Date of Patent: July 22, 2003Assignee: Pioneer Plastics CorporationInventors: Daniel C. Nelson, Robert A. Dumond

Patent number: 4777093Abstract: A carbonizable body is formed by infusing a plurality of preoxidized (preferably stabilized by known processing to have about 9 to 14 weight percent oxygen) polyacrylonitrile fibers in a polar liquid plasticizer, preferably water, capable of extracting a tarry leachate from the fibers. The infusion of the fibers in the plasticizer is continued for a sufficient time for a substantial amount of leachate to form on the surface of the fibers, and are then consolidated or diffusion-bonded to one another or other fibers, as by orienting the treated fibers in a mold and subjecting them to isostatic pressing at relatively low temperatures and pressure. Further processing of the consolidated fibers with appropriate heat treatment in an inert atmosphere will produce a carbonized bulk product with higher values of Young's modulus for the carbonized material than have been previously achieved at such carbonization temperatures.Type: GrantFiled: April 9, 1987Date of Patent: October 11, 1988Assignee: Fiber Materials, Inc.Inventors: Daniel C. Nelson, Roger T. Pepper

Patent number: 4776994Abstract: A carbonizable body is formed by infusing a plurality of preoxidized, preferably stabilized by known processing to have about 17 to 30 weight percent oxygen, fibers prepared from pitch, in a non-polar liquid plasticizer, typically quinoline, capable of extracting a tarry leachate from the fibers. The infusion of the fibers in the plasticizer is continued for a sufficient time for a substantial amount of leachate to form on the surface of the fibers. The treated fibers are then consolidated or diffusion-bonded to one another or other fibers, as by orienting the treated fibers in a mold and subjecting them to isostatic pressing at relatively low temperatures and pressure.
