Patent number: 8444808Abstract: A process for making nanofibers includes preparing a fluid suspension of fibers, shear refining the fibers to create fibrillated fibers, and subsequently closed channel refining or homogenizing the fibrillated fibers to detach nanofibers from the fibrillated fibers. The shear refining of the fibers in the fluid suspension generates fiber cores having attached nanofibers. The closed channel refining or homogenizing of the fibrillated fibers is initially at a first shear rate and, subsequently, at a second, higher shear rate, to detach nanofibers from fiber cores and to create additional nanofibers from the fiber cores. The fiber suspension may flow continuously from the shear refining to the closed channel refining or homogenizing, and include controlling the rate of flow of the fiber suspension from the shear refining to the closed channel refining or homogenizing.Type: GrantFiled: March 30, 2007Date of Patent: May 21, 2013Assignee: KX Industries, LPInventors: Evan E Koslow, Anil C Suthar

Patent number: 8444807Abstract: The invention relates to a method for preparing paper pulp from recycled paper containing contaminants characterized in that it comprises a first step of agitating the paper in the presence of water in order to obtain a mixture of fibers and contaminants in suspension, a second step of coarsely screening said mixture in order to separate the coarse contaminants from the rest of the suspension, a third step of fine screening in order to separate the fine contaminants from the coarsely-screened suspension and a fourth step of washing said coarse and fine contaminants in order to separate the reusable fibrous materials from the rest of the non-reusable contaminants. In particular, the invention aims to provide a method for preparing paper pulp that is capable of producing a good quality paper pulp from highly-contaminated recycled paper, especially having a contaminant level in the dry state that is greater than or equal to 15% by weight.Type: GrantFiled: December 20, 2006Date of Patent: May 21, 2013Assignee: SCA Tissue FranceInventors: Philippe Colin, Philippe Beringuet, Xavier Gillot, Jean-Yves Tinel

Patent number: 8444810Abstract: A process for treatment of fibers is disclosed. The treatment comprises simultaneously and continuously macerating the fibers and exposing the fibers to superheated steam, ammonia gas and ethylenediamine gas. The treatment is carried out in a chamber where the fibers are subjected to the mechanical rubbing and crushing action of a plurality of rotating pins against channels disposed on the chamber interior wall. The treatment results in improved fiber water holding capacity and improved conversion efficiency in the production of ethanol from the treated fibers.Type: GrantFiled: November 21, 2010Date of Patent: May 21, 2013Inventor: Aicardo Roa-Espinosa

Patent number: 8343313Abstract: The production equipment of paper-made components for loudspeakers includes a mixing device, a fining device, a paper-making device, and a shape processing device. The mixing device mixes material of a paper-made component for a loudspeaker into liquid to generate mixed liquid. The fining device includes a pressure unit, an orifice, and an inner wall. The pressure unit applies pressure on the mixed liquid to cause the mixed liquid to pass through the orifice, and the mixed liquid collides against the inner wall to cause the fining device to generate fined material. The paper-making device paper-makes the fined material to generate a paper-made component. The shape processing device processes the shape of the paper-made component. This structure provides production equipment of the paper-made components for loudspeakers, which prepares material for paper-making in a short time and reduces producing time.Type: GrantFiled: February 23, 2007Date of Patent: January 1, 2013Assignee: Panasonic CorporationInventors: Kazuyoshi Mimura, Kenichi Ajiki, Shinya Mizone, Masahide Sumiyama, Toru Fujii
