Howard M. Clearfield 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: 8468750
    Abstract: Seal a flashing joint on an open frame structure using a first barrier sheet having first and second adhesive strips on opposing primary surfaces proximate to opposing edges and running the length of the first barrier sheet by applying the first barrier sheet over the flashing joint with one edge below the flashing joint and adhering an adhesive strip to a building element below the flashing joint with the first adhesive strip and applying a second barrier sheet overlapping the first barrier sheet and adhere the first and second barrier sheets together using the second adhesive strip. The process can include applying flashing over the first barrier sheet and flashing joint and then overlaying the flashing with the second barrier sheet and sealing the second barrier sheet to both the first barrier sheet and the flashing.
    Type: Grant

  • Patent number: 5569501
    Abstract: The present invention relates to an improved method of depositing a diamond-like carbon film onto a substrate by low temperature plasma-enhanced chemical vapor deposition (PECVD) from a hydrocarbon/helium plasma. More specifically, the diamond-like carbon films of the present invention are deposited onto the substrate by employing acetylene which is heavily diluted with helium as the plasma gas. The films formed using the process of the present invention are characterized as being amorphous and having dielectric strengths comparable to those normally observed for diamond films. More importantly, however is that the films produced herein are thermally stable, optically transparent, absorbent in the ultraviolet range and hard thus making them extremely desirable for a wide variety of applications.
