Patent number: 10821384Abstract: An air/gas filter medium is comprised of a substantially homogeneous core layer of feather down clusters held together by a binder to form a 3-dimensional interconnected filament structure throughout the core. The filament structure forms air pocket and connect and trap the feather down clusters which form minute air pockets between its filaments and hairs in which undesirable substances from an air/gas flow therethrough are captured. An air permeable scrim sheet is retained on a surface of the down cluster core. The down cluster core is compressed to a predetermined density to modify the average size of said minute air pockets to trap known undesirable substances from the air/gas flow.Type: GrantFiled: August 28, 2017Date of Patent: November 3, 2020Inventor: Ronie Reuben

Publication number: 20110094691Abstract: Processes for producing regenerated fibers from post-consumer and post-industrial waste are disclosed. The process generally involves obtaining a source of post-industrial and/or post-consumer scrap material comprising fibers, cutting the material into a desirable size in the range of from one square inch to thirty square inches, detangling the fibers, removing any finish from the fibers, if present, combing and/or picking the fibers to convert any threads into fibers, humidifying the fibers, and intimately blending the fibers. These regenerated fibers can be blended with other fibers, and intimately blended to provide a uniform blend of fibers. The fibers can then be subjected to a carding process to orient the fibers. The regenerated fibers can be used in any application that would otherwise use virgin fibers, including their use to form woven or non-woven materials.Type: ApplicationFiled: October 25, 2009Publication date: April 28, 2011Inventor: Kayren J. Nunn

Patent number: 7862684Abstract: The invention relates to the use of a particulate material derived from mammalian hair in the preparation of a paper or paperboard product, which particulate material has been prepared by means of a process, which comprises the following steps: (a) subjecting mammalian hair to an oxidation treatment in which the hair is contacted with a solution, which comprises a bleaching agent; (b) separating the oxidised hair from the solution; (c) drying the separated hair; and (d) subjecting the dried hair to a treatment in which the hair is formed into a particulate material having an average particle size in the range of from 0.5 to 4 mm. The invention further relates to a paper or paperboard product, or paper pulp comprising said particulate material.Type: GrantFiled: February 18, 2005Date of Patent: January 4, 2011Assignee: Nederlandse Organisatie Voor Toegepast-Natuurwetenschappelijk Onderzoek TNOInventors: Theodoor M. Slaghek, Mario T. R. van Wandelen, Willem C. Drost, Dario M. R. Lo Cascio, Remco W. G. van Willige, Willem Huijser

Publication number: 20020148572Abstract: A feather molding process and the molded product produced therefrom. The inventive method comprises the steps of: (a) reducing feathers in a refiner, a pulper, or a combination thereof; (b) cleaning the feathers using a cleaning agent; (c) diluting at least a portion of the reduced feather material to form a slurry; and (d) delivering the slurry to a vacuum molding apparatus to form a molded product.Type: ApplicationFiled: April 26, 2002Publication date: October 17, 2002Applicant: Tyson Foods, Inc.Inventor: Barry Allen Griffith

Publication number: 20020079074Abstract: A method of processing feathers and products produced thereby. The method preferably comprises the step of reducing feathers in at least one of a refiner and a pulper. A cleaning agent is preferably added to the feather material before and/or after the reducing step. The cleaning agent will preferably be hydrogen peroxide, detergent, a surface acting surfactant, bleach, or a combination thereof. The method can also include the steps of (a) adding paper pulp to the reduced feather material and then (b) forming a product from the combined material.Type: ApplicationFiled: November 8, 2001Publication date: June 27, 2002Inventor: Barry Allen Griffith

Patent number: 6027608Abstract: A process for converting components of poultry production feather waste into value-added products involves a single counterflow or batch system wash in a polar organic solvent solution. The feather waste can contain loose, picked feathers, and non-feather avian parts. The feather-waste stream is exposed to a concentration gradient of solvent which sanitizes, denatures, dehydrates, and de-oils it. In one aspect, the counterflow contact between solvent solution and feather waste takes place in an inclined screw conveyor. The process produces avian oil and protein from a liquid intermediate stream and dry fiber and protein powder from the converted waste stream. Fiber from this process can be used in fabrics, composites, extrusions and laminates. Oil and protein can be used in biochemical, pharmaceutical, cosmetic, animal feed, and fertilizer products.Type: GrantFiled: March 12, 1999Date of Patent: February 22, 2000Assignee: Origin Technology, IncInventor: George Gassner

Patent number: 5882476Abstract: This invention is a method for deinking wastepaper by disintegrating the waste paper in an carbonate aqueous solution containing sodium sulfite and sodium carbonate to produce a fibrous slurry having a pH of at least 7.5, separating the ink from the fibers and removing the ink from the slurry. A composition useful for deinking fiber consists of a relative proportion of sodium sulfite to sodium carbonate between about 95:5 and about 50:50, and a surfactant.Type: GrantFiled: May 5, 1995Date of Patent: March 16, 1999Assignee: Solvay Minerals, Inc.Inventors: Emmett J. Evans, Stuart G. Guthrie

Patent number: 4958012Abstract: A novel squid chitin formed material is disclosed. Squid chitin is prepared by pulverizing squid crust and treating the pulverized chitin with caustic soda and then with hydrochloric acid to remove proteins and ashes. Squid chitin formed material such as sheet or fiber is then prepared by a freeze-defrost treatment. The squid chitin sheet and fiber have better physical properties than conventional crab chitin formed materials in terms of strength and folding endurance.Type: GrantFiled: March 7, 1989Date of Patent: September 18, 1990Assignee: Nippon Suisan Kaisha, Ltd.Inventors: Seiichi Tokura, Tsuyoshi Koriyama, Yoshiyuki Chiba, Mikio Satake
