Patent number: 8959002Abstract: Readings of a characteristic of the yarn along the longitudinal direction of the yarn are detected. Values of a yarn parameter are determined from the readings. An event field contains a quadrant of a two-dimensional Cartesian coordinate system, whose abscissa defines an extension of yarn parameter values in the longitudinal direction and whose ordinate defines a deviation of the yarn parameter from a desired value. Densities of events in the event field are determined from the values of the yarn parameter and their extensions in the longitudinal direction. A yarn body is represented as an area in the event field. The area on the one hand is delimited by the abscissa, on the other hand by the ordinate and further by a line in the event field that substantially follows a constant event density. The representation of the yarn body permits a clearing limit to be defined in a rapid and rational manner.Type: GrantFiled: December 8, 2009Date of Patent: February 17, 2015Assignee: Uster Technologies, AGInventors: Beat Keller, Stefan Gehrig, Peter Schmid, Loris De Vries

Patent number: 8957688Abstract: An apparatus for determining at least one dielectric property of a capacitor arrangement, and especially for capacitive examination of a moving elongated test subject such as yarn. It contains an alternating signal generator for applying an electric alternating signal to the capacitor arrangement. The capacitor arrangement is uncoupled from the alternating signal generator by means of an amplifier in such a way that it does not relevantly influence the basic frequency and the signal shape of the applied alternating signal. Detection means detect an electric measuring variable of an electric signal tapped from the capacitor arrangement. The alternating signal generator is set up in such a way that at least one of the basic frequency and the signal shape of the applied alternating signal can be changed.Type: GrantFiled: October 12, 2009Date of Patent: February 17, 2015Assignee: Uster Technologies, AGInventor: Reto Gehrig

Publication number: 20150034751Abstract: A combination of a disc-type yarn tensioner is proposed, comprising a pneumatic cleaning device, which is fixedly assigned thereto. The disc-type yarn tensioner comprises an axle on which two brake plates are rotatably mounted by means of one rotary bearing each. It further comprises a pressure mechanism for applying axial pressure forces to the brake plates, which pressure forces press the brake plates against each other. The pneumatic cleaning device comprises at least one nozzle whose flow axis is directed from the outside substantially towards one of the rotary bearings. The compressed air flow exiting from the nozzle cleans the disc-type yarn tensioner. It is thus ensured that the rotary bearings of the brake plates accumulate less dirt and the rotary movement of the brake plates is braked with the intended braking force.Type: ApplicationFiled: March 1, 2013Publication date: February 5, 2015Applicant: USTER TECHNOLOGIES AGInventors: Benno Grob, Martin Kuster

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.
