The nails are driven into the panel layers from both major face surfaces of the panel and are angled from the perpendicular of the major face surfaces of the panel to increase the probability of a penetrating instrument striking a nail during a penetration attempt. The panel is covered in a layer of sheet metal, and a layer of Kevlar or some other ballistic resistant material is placed on one or more major face surfaces. Rabbet edges on the panel allow an assembly with reinforced seams, and two single panels may be secured together to form a double reinforced vault panel.

  • Patent number: 5402703
    Abstract: The invention provides a three layer liner for armor to reduce spall and the spall angle. The liner provides a high impedance.The liner is formed by layers of silastic rubber with tungsten powder. Successive layers have a decreasing concentration of tungsten powder, causing the density of the successive layers to decrease. This decreasing density causes the high impedance of the liner. The liner is made by casting a layer of the silastic rubber with the tungsten powder mixed in with a second layer of silastic rubber with a lower density of tungsten powder. The material is then pressed into a sheet. One side of the sheet is wet with silastic rubber and merged with a fabric layer.

  • Patent number: 5329864
    Abstract: A break-in obstructing, or burglarproof door or wall, for which old motor vehicle tires are used as filling units instead of steel structures and sheeting. The treads or strips separated from the tires form mat-like, layered, and/or stacked filling units for burglarproof doors or walls and are connected with each other and to the frame by special fastening devices. This application considerably reduces the weight of such a door, and allows for burglarproof and break-in obstructing doors and walls at a much lower production cost, due to using recycling material.

  • Patent number: 5299862
    Abstract: This structure relates to storage devices and in particular to lockers in particular for luggage such as those to be found at airports and railway stations. The lockers of the present device comprise a door, preferably with no moving parts, which, when the locker is not in use, is permanently biased open and thus in an unlocked position. When the locker is in use the door can be secured merely by shutting the door of the locker. A number of lockers of the present invention can be incorporated into columns of lockers under the control of a central control unit which dispenses appropriate receipts and tickets in exchange for money.

  • Patent number: 5257583
    Abstract: A lightweight, multilayered panel for use in a modular vault or safe structure has multiple layers of cross-grained wood boards secured together by a grid of hardened masonry nails. The nails are driven into the panel layers from both major face surfaces of the panel and are angled from the perpendicular of the major face surfaces of the panel to increase the probability of a penetrating instrument striking a nail during a penetration attempt. The panel is covered in a layer of sheet metal, and a layer of Kevlar or some other ballistic resistant material is placed on one or more major face surfaces. Rabbet edges on the panel allow an assembly with reinforced seams, and two single panels may be secured together to form a double reinforced vault panel.

  • Patent number: 5069358
    Abstract: A fire-resistant case for protecting electronic storage media includes a main body and lid, each of which is assembled from a pair of subassemblies. The outer subassemblies of the lid and main body are made from an integral resin body having inner, outer, and intermediate shells for encasing a layer of water-bearing material. The outer shells form the outer skin of the case, the inner shells form a moisture-resistant layer, and the intermediate shells form an outer seal between the main body and lid. An inner subassembly of the main body is built up from an inner repository of heat-conducting material, slabs of phase-changing material, and a foam insulation that encases the inner respository and phase-changing material. The foam insulation is formed as a self-skinning foam for forming a part of an inner seal between the main body and lid. An inner subassembly of the lid is constructed in a variety of ways consistent with the purposes of the other named layers of the case.

  • Patent number: 5014593
    Abstract: Perforated plate armor (10) for protecting an object (12) from damage includes outer and inner perforated steel plates (14) and (18) which have associated patterns of holes (16,20). These perforated steel plates (14,18) are heat treated to have hardened surfaces and a more ductile core and are spaced with respect to each other at outer and inner locations with respect to the object (12) to be protected. The patterns of holes (16,20) of the perforated steel plates (14,18) are offset with respect to each other to prevent straight line penetration of any particle through both plates. An inner backing plate (28) preferably made of aluminum is also provided to stop any particles that might penetrate both perforated steel plates (14,18). Fillers (22,24) and connectors (26) space the outer and inner perforated steel plates (14,18) and the aluminum backing plate (28) with respect to each other.
