  • Seal compression indication system
    Patent number: 6879256
    Abstract: A watertight door seal compression indication apparatus is provided that includes a watertight door in a frame that has a casket disposed in a channel around the periphery of the door. A knife-edge on the doorframe is positioned to compress the gasket upon latching the door shut. Numerous switches are placed between the channel and the gasket and the switches are closed when the knife-edge edge fully compresses the gasket. A display that is responsive to the switches indicates whether the gasket was sufficiently compressed or not by either a green LED or a red LED respectively.
