Patents by Inventor Mark Edmund Weber

Mark Edmund Weber has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Polyethylene compositions and closures for bottles
    Patent number: 9221966
    Abstract: A dual reactor solution process gives high density polyethylene compositions containing a first ethylene copolymer and a second ethylene copolymer and which have good processability, toughness, and environmental stress crack resistance combined with good organoleptic properties. The polyethylene compositions are suitable for compression molding or injection molding applications and are particularly useful in the manufacture of caps and closures for bottles.
    Type: Grant
    Filed: December 2, 2014
    Date of Patent: December 29, 2015
    Assignee: NOVA Chemicals (International) S.A.
    Inventors: XiaoChuan Wang, Yves Lacombe, Mark Edmund Weber

  • Method of selecting a plastic
    Patent number: 8965738
    Abstract: A plastic may be selected for a thin web application by finite element analysis of the part including the properties, including Poission's ratio of potential polymers from which the part may be made and subjecting the computer model of the part to loads to determine the deflection of the part under a specified series of loads or when the part breaks or subjecting the part to a number of use cycles to determine when the part fails. The process is iteratively repeated for each plastic and the results are compared to select a preferred plastic for the part.
