  • Systems and methods for drying a compressed gas
    Patent number: 9687778
    Abstract: Systems, equipment and methods suitable for drying a gas, for example a compressed gas, that utilize a drying cycle during which the gas flows through one or more dryer tanks and a desiccant material therein adsorbs a liquid entrained in the compressed gas to produce a dried compressed gas. A regeneration cycle is employed during which a purge gas flows through a purge gas dryer tank. During one or more phases of the regeneration cycle, a desiccant material within the purge gas dryer tank is employed to adsorb water vapor entrained in the purge gas to produce a dried purge gas, which is then directed through the dryer tank as part of the regeneration cycle performed on the desiccant materials within the dryer tanks.

  • Polyester containers having a reduced coefficient of friction
    Publication number: 20030152726
    Abstract: Polyester containers having a reduced coefficient of friction (“COF”) are produced by increasing the surface roughness of the polyester using either thermal crystallization or solvent crystallization. Because the low COF reduces or eliminates friction between polyester containers, the containers do not become entangled and disrupt the manufacturing process. As a result, the containers move easily through typical conveying and filling lines in manufacturing processes that use the containers.

  • Device and method for the optical inspection, assessment, and control of colored plastic articles and/or container contents
    Publication number: 20020033943
    Abstract: The present invention relates to an apparatus and method for detecting defects in colored articles. Specifically, the present invention comprises exposing a plastic colored article to radiation in the near infrared range; measuring radiation returned from or passed through said article and analyzing said returned or passed radiation to provide defect data for said article or contents within said article.
