Patent number: 8875897Abstract: An apparatus for processing a sample including fibers and trash, having a cylinder rotating in a first direction for receiving the sample. The cylinder has a surface with rigid pins. The pins engage and retain the fibers of the sample. A collection surface receives the trash that falls from the cylinder. A counter-flow of air moves in a separation region between the cylinder and the collection surface in a direction that is substantially perpendicular to and towards the underside of the cylinder. The counter-flow of air has at each position within the separation region an air-flow velocity that is sufficient for the counter-flow of air to blow the fibers that are not originally retained by the pins up toward the cylinder and thereby engaging the fibers with the cylinder, and yet insufficient to prevent gravity from pulling the trash downward through the counter-flow of air.Type: GrantFiled: June 25, 2013Date of Patent: November 4, 2014Assignee: Uster Technologies AGInventors: Youe-Tsyr Chu, Johnathan W. Craps, Weichang Zhao, Michael E. Galyon, Hossein M. Ghorashi

Publication number: 20120158342Abstract: A method for measuring the weight of impurities in a mixed volume of fibers and impurities by mechanically separating the impurities are from the fibers, whereupon some undesired fibers still remain admixed to the impurities due to imperfections of the mechanical separation. A total weight of the separated impurities and the undesired fibers is gravimetrically measured. An image of the separated impurities and the undesired fibers is created. A weight of the undesired fibers is estimated from the image. The estimated weight of the undesired fibers is subtracted from the total weight to yield a corrected weight of the impurities. The mechanical separation and the subsequent electronic correction yield a more accurate weight of the impurities.Type: ApplicationFiled: May 5, 2011Publication date: June 21, 2012Applicant: USTER TECHNOLOGIES AGInventors: Youe-Tsyr Chu, Preston S.

Patent number: 7278186Abstract: An apparatus for measuring a moisture content value within a volume. A frequency generator generates at least one source signal at frequencies of no more than about one kilohertz. Probes are disposed with surfaces in physical contact with the volume, where no direct current flows between the probes through the volume. One of the probes is electrically connected to the frequency generator as a source probe, and adapted to receive the source signal and emit the source signal into the volume, thereby creating an electrical field having characteristics that are dependent at least in part on a moisture content of the volume. Another of the probes operates as a receiver probe for sensing the electrical field and producing an output signal having an output property that is dependent at least in part on the source signal and the moisture content within the volume.Type: GrantFiled: January 5, 2005Date of Patent: October 9, 2007Assignee: Uster Technologies AGInventors: Glenn E.

Patent number: 6188479Abstract: An apparatus for delooping fibers in a fluid flow preferably includes a cyclone for receiving entities from a fiber individualizer and delivering individual fibers to a sensor. The fluid flow rate to the cyclone is set to optimize operation of the individualizer and the flow rate from the cyclone is set to optimize operation of the sensor. A nozzle is provided in the sensor for mechanically delooping the fibers so they are sensed in a straight condition. In addition, electronics associated with the sensor detects sensor signals corresponding to looped fibers and electronically “deloops” the fibers to produce data, such as the actual length of a fiber that was presented to the sensor in a looped condition.Type: GrantFiled: February 21, 1995Date of Patent: February 13, 2001Assignee: Zellweger Uster, Inc.Inventors: Frederick M.

Patent number: 6052182Abstract: A fiber quality monitoring apparatus is constructed with a sample window for viewing a fiber sample. As the fiber sample passes the sample window, a bulb is strobed to produce a light pulse that is directed toward and reflected by the fiber sample. When the light pulse reaches a desired intensity, a first photo diode generates a synchronization signal. A second photo diode detects reflected light with a wavelength between about 500 nanometers and about 600 nanometers and produces a reflection signal. A third photo diode detects reflected light with a wavelength between about 430 nanometers and about 530 nanometers and produces a color signal. A charge coupled device camera is positioned to receive the reflected light pulse. The charge coupled device camera has an array of pixels which receive the reflected light pulse.Type: GrantFiled: October 28, 1997Date of Patent: April 18, 2000Assignee: Zellweger Uster, Inc.Inventors: Glenn E.

Patent number: 6040905Abstract: A fiber classing device having a sample window for viewing a fiber sample. A light source provides light that is directed toward and reflected by the fiber sample, producing reflected light. A photo sensitive detector is positioned to receive the reflected light, and it detects lightness, redness, and yellowness of the fiber sample. Processing means assign a preliminary grade to the fiber sample based at least in part on the lightness and yellowness of the fiber sample. The processing means also selectively adjust the preliminary grade to a final grade based at least in part on the redness of the fiber sample. The photo sensitive detector has one or more of a spectrometer, a camera, or a set of three photo diodes. A first photo diode detects light with a wavelength of between about 505 nanometers and about 605 nanometers, corresponding to the lightness of the fiber sample.Type: GrantFiled: August 5, 1998Date of Patent: March 21, 2000Assignee: Zellweger Uster, Inc.Inventors: Luo Cheng, Glenn E.

Patent number: 6020744Abstract: An apparatus measures moisture content of cotton based upon rates of electrical charges flowing through the cotton. The apparatus includes a moisture sensor having first electrodes, second electrodes, and ground electrodes which are interdigitated between the first and second electrodes. The apparatus also includes a moisture content determination circuit that provides first electrical charges to the first electrodes, and second electrical charges to the second electrodes. The moisture content determination circuit determines the rate of electrical charge flowing from each of the first and second electrodes through the cotton to the ground electrodes, and determines the moisture content of the cotton based upon the rates of electrical charges flowing through the cotton. By thus applying first electrical charges to the first electrodes and second electrical charges to the second electrodes, the apparatus accurately measures the moisture content of the cotton over a wide range of moisture contents.Type: GrantFiled: November 4, 1997Date of Patent: February 1, 2000Assignee: Zellweger Uster, Inc.Inventors: Hossein M.
