  • Low-wear fluoropolymer composites
    Patent number: 9982209
    Abstract: A low-wear fluoropolymer composite body comprises at least one fluoropolymer and additive particles dispersed therein. Also provided is a process for the fabrication of such a fluoropolymer composite body. The composite body exhibits a low wear rate for sliding motion against a hard counterface, and may be formulated with either melt-processible or non-melt-processible fluoropolymers.
    Type: Grant
    Filed: December 20, 2013
    Date of Patent: May 29, 2018

  • Method for designing and applying a Kaiser window filter for enlarging or reducing an image
    Patent number: 5294998
    Abstract: The present invention relates to a method of designing a Kaiser window filter. The filter is applied to an input image to generate a resized output image while preserving the information content of the input image. The method of mapping the output image space to the input image space of the present invention aligns the boundaries of the input image space with the boundaries of a set of new input pixels, and the coordinate points of the output pixels map to corresponding coordinate points of the new input pixels.

  • Inferential time-optimized operation of a fiber producing spinning machine by computerized knowledge based system
    Patent number: 4916625
    Abstract: A method for monitoring the operation of a multiposition spinning machine wherein filaments are extruded from a spinning pack at each position and advanced as a yarn bundle in a path, then split at a location into a plurality of threadlines to be forwarded to a plurality of windups to be wound on packages and scheduling events at predetermined times in the preparation of said packages with the aid of a digital computer, the method relies on a program with a knowledge database that includes the operative state of each position, the elapsed time since the initiation of each package, predetermined event times unique to the filaments being wound, the positional configuration of said machine, a hueristic rule base.
