  • Patent number: 5017736
    Abstract: A door which is magnetically shielded and RF-shielded is disclosed for use with magnetically and RF-shielded room enclosures in which the door is slidably disposed within the space between the outer and inner enclosure of a shielded room, the door being actuated by pneumatic cylinders situated within the door which pressurize the door so that the door makes contact, and a tight seal, with the inner and outer enclosure walls.
    Type: Grant

  • Patent number: 4959504
    Abstract: A self-contained room capable of shielding the interior environment from magnetic and radio frequency interferences, as well as other wave and vibrational disturbances, comprised of an outer enclosure and an inner enclosure, raised above an existing floor by a fiberglass dowel system. The walls of both enclosures are made of mumetel sheets, pressure sealed to protect against ambient and man-made interferences, with an underlying aluminum structural frame. All seams and penetrations are shielded against wave interferences of natural or man-made origin.
