  • Fully consumable remotely operated seal
    Patent number: 4402516
    Abstract: A method for sealing ports, ducts and the like using a fully consumable mrial as the sealing medium and utilizing the consumable capability to provide remote removal of the seal without damage to the sealed areas and with no remaining obstruction in the port, duct or the like. The fully consumable seal may be configured to the geometry of the aperture to be sealed and has thickness determined by pressure difference across the seal and time required to remove the seal.
