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.

Low-wear fluoropolymer composites

A process and apparatus for forming nanofibers from a spinning melt utilizing a high speed rotating distribution disc. The fibers can be collected into a uniform web for selective barrier end uses. Fibers with an average fiber diameter of less that 1,000 nm can be produced.

Production of nanofibers by melt spinning

Disclosed is a composition comprising or produced from nanoparticle-sized TiO, an ethylene copolymer or ionomer of the ethylene copolymer, and optionally a second polymer. Also disclosed are films and other shaped articles produced therefrom. The composition, possessing a UV light barrier, can be used to protect the products that may be susceptible to UV such as foodstuffs.

Composition comprising nanoparticle TiO2 and ethylene copolymer

Disclosed is a process for controlling extrusion processes by applying dynamic periodic pulses to the process throughout and during the process, analyzing the pulse response data and feeding back the results of the analysis to the process parameters and product properties.

Method for control of extrusion process

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.

Method for designing and applying a Kaiser window filter for enlarging

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. The operative state of each position is sensed by monitoring the presence or absence of the advancing yarn bundle and threadlines as a function of time and this information is provided to the computer which compares the operative state of each position and the elapsed time since initiation of each package and indicates that the time for performing said events has been reached.
