Further, the cyclodextrin material can be included in a thermoplastic film that can be used as one layer in a bilayer or multilayer laminate containing a cellulosic web.Type: GrantFiled: July 6, 1998Date of Patent: November 16, 1999Assignee: Cellresin Technologies, LLCInventors: Willard E. Wood, Neil J. Beaverson

Patent number: 5972264Abstract: A method for fabricating fiber-reinforced composite structures, including centrifuge rotors, by resin transfer molding (RTM) is disclosed. The method involves loading reinforcing fibers into a mold and then injecting resin into the mold to coat the fibers to form the composite structure. Two types of reinforcing fibers are used--fabric preforms at the surfaces of the structure and chopped fibers at the interior of the structure. Also disclosed is a fiber-reinforced composite structure comprising a skin layer of reinforcing fabric, chopped fibers distributed throughout the interior of the structure, and epoxy resin that binds the fabric and chopped fibers together into a fiber-reinforced composite structure. The resin transfer molding method is especially useful for fabricating composite centrifuge rotors.Type: GrantFiled: June 6, 1997Date of Patent: October 26, 1999Assignee: Composite Rotor, Inc.Inventors: Mohammad Ghassem Malekmadani, Charles Biddle, Hung Nguyen, Reza Sheikhrezai

Patent number: 5972807Abstract: A film forming, photosensitive, heat-resistant resin composition including a varnish of a polyimide precursor having no photosensitivity in itself, a polymeriziable monomer or oligomer compatible with the varnish and capable of providing a high-heat-resistant polymer upon being polymerized, and a polymerization initiator for the monomer or oligomer. The resin composition is useful for the production of circuit substrates and semiconductor devices for high-density mounting, since it can effectively avoid a reduction of the layer thickness during film formation, and ensures a low cost production process. The pattern formation process using such a resin composition is also disclosed. The polymeric composite having a particles-in-matrix microstructure and the production process thereof are also disclosed.Type: GrantFiled: December 23, 1996Date of Patent: October 26, 1999Assignee: Fujitsu LimitedInventors: Motaki Tani, Eiji Horikoshi, Isao Watanabe, Shoichi Miyahara, Takashi Ito, Makoto Sasaki

Patent number: 5955386Abstract: An open weave, air permeable fiber pad is formed from a plurality of compressed, interlocked fiber strands. A non-uniform, three dimensional grid of spaced apart, expandable graphite particles are secured at randomly spaced apart intervals to individual fiber strands with a particle distribution density sufficient to form a barrier to air flow through a defined area of the fiber pad when exposed to a source of heat causing the expandable graphite particles to be converted from their normal volume to a heat-activated, substantially expanded volume.Type: GrantFiled: November 25, 1998Date of Patent: September 21, 1999Inventor: Bill D. Horton

Patent number: 5786280Abstract: Carpet material with at least a proportion of uncleaned used carpets is shredded to form a fiber-like wooly mass. The carpet material contains a thermoplastic binder with a low melting point, for example polypropylene, which can be derived from the used carpets or be added. Furthermore, a duroplastically hardening binder, for example phenolic resin, is added to the carpet material. The carpet material is compressed to form the molded part or panel with these two binders, at a temperature which lies above the plasticizing point of the thermoplastic binder, but below the plasticizing point of any other thermoplastic components of the carpet material.Type: GrantFiled: June 23, 1994Date of Patent: July 28, 1998Assignee: Eduard Kusters Maschinenfabrik GmbH & Co. KGInventors: Bernhard Funger, Heinz Gruber
