Alan J. DeMello 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).

  • Patent number: 5788889
    Abstract: In a process for extruding a low density foam, a foamable thermoplastic elastomer such as a thermoplastic rubber is selected. The selected thermoplastic elastomer is then fed into a heated extruder barrel where it is compressed and melted by the action of a screw. A blowing agent consisting of water is introduced into the melted thermoplastic elastomer. The melted thermoplastic elastomer and the water are thoroughly mixed and then cooled to a uniform, predetermined temperature. The mixture is then forced through a die to form an extruded foam profile.
    Type: Grant
    Filed: March 3, 1997
    Date of Patent: August 4, 1998
    Assignee: Amesbury Group, Inc.
    Inventors: Alan J. DeMello, Douglas W. Hartford, Peter E. Mertinooke, Dan C. Muessel, Louis Halberstadt

  • Patent number: 5522602
    Abstract: One embodiment of a gasket for shielding electromagnetic interference passing through a seam between first and second electrically conductive bodies includes a base for securing the gasket to the first, electrically conductive body and a multiplicity of discrete, elongate, metallized filaments projecting substantially perpendicularly from the base so that a substantial amount of the filaments contacts the second, electrically conductive body when electromagnetic interference passing through a seam between the bodies is to be shielded. The gasket further includes structure, arranged with the base, for providing an electrically conductive path for conducting electric current between the filaments and the first, electrically conductive body. In this manner, energy absorbed the shielding member as a result of the shielding of passing electromagnetic interference can be dissipated to ground through the first, electrically conductive body.
