Patent number: 4178859Abstract: A door-like closure for passageways in high-risk high-security installations includes a multilayer protective plate which has a rather high resistance to mechanical, thermal and chemical damaging influences, but which can be rather easily damaged by the action of explosives. To reinforce the protective plate, a reinforcing grid is juxtaposed therewith at the major surface thereof which faces the interior of the installation so that, when an attempt is made to destroy the protective plate by explosives, the reinforcing grid not only will increase the resistance of the protective plate to damage but also will permit the explosive shockwave and the possible debris of the protective plate propelled thereby to penetrate through the apertures of the grid without causing any considerable damage to the grid. The apertures of the grid have such dimensions that an intruder will not be able to reach through the aperture into the interior of the installation to, for instance, manipulate the lock of the closure.Type: GrantFiled: August 30, 1977Date of Patent: December 18, 1979Assignee: Bochumer Eisenhutte Heintzmann GmbH & Co.Inventors: Rudolf Seiz, Heinz Eickhoff, Herbert Meyer, Dieter Steppke

Patent number: 4048926Abstract: A safe has a self-sealing jamb where the door confronts and fits together with the box. This is done by forming the confronting surfaces in the jamb region of a resin material and making the jamb region non-linear in cross section and long enough in cross section so that after an outer portion of the resin material is burned off in a fire, a charred residue and a plasticized portion of the resin material remain in the jamb region to seal the door to the box around the jamb region for substantially preventing heat conduction or passage of hot gasses through the jamb region to the interior of the box. The safe can also be formed in a resin mold for the box and the door with the mold remaining in place when the safe is used. The mold is preferably filled with a non-flammable, thermal insulating material having a substantial volume of chemically bonded water and made thick enough to maintain the interior of the box below 180.degree. C for one hour in an ambient atmosphere of about 927.degree. C.Type: GrantFiled: January 12, 1976Date of Patent: September 20, 1977Assignee: John D. Brush & Co., Inc.Inventors: John D.
