  • Inflatable liner systems
    Patent number: 9038803
    Abstract: An inflatable liner with vibratory function related to lining mining hoppers and other such devices. The inflatable liner has an exterior expandable layer and ceramic wear layer beneath that assists maintaining a long-use-life of the inflatable liner. Use of the air-control device to rapidly inflate and deflate exterior expandable layer vibrates in the exterior expandable layer and assist removing unwanted material/debris from the exterior lining of exterior expandable layer to further maintain a long-life use of the inflatable liner and lower maintenance of the machinery/hopper.
    Type: Grant
    Filed: December 30, 2013
    Date of Patent: May 26, 2015
    Assignee: Corrosion Engineering, Inc.
    Inventors: Donald C. Dunn, Jerry F. Hofberger
