  • Patent number: 5575339
    Abstract: An expandable metal product for use in extinguishing fires and in the prevention of or protection against explosions. The product is a continuous sheet of magnesium alloy foil having discontinuous slits in spaced apart lines parallel to each other but transverse to the longitudinal dimension of the sheet. The invention is also directed to the expanded form of the product, either in sheets which may be used for preventing fires or explosion or in the form of shaped ellipsoids for use in a passive inerting system for fuel tanks.

  • Patent number: 5576511
    Abstract: A highly efficient anti-explosion pad comprising multiple sheets of expanded metal net separated by a core layer of porous material such as fiberglass, cotton batting or an assembly of miniature ellipsoids or balls formed from expanded metal net. When covering a wall or other structural element, the stratiform pad effectively dissipates the shock waves and thermal effects of a close range bomb explosion.

  • Patent number: 5540285
    Abstract: A highly efficient fuel containment medium which is adapted to protect neighboring facilities against fire or explosion of flammable materials accidentally released from above-ground storage tanks. The fuel containment medium has special applicability for use in diked areas surrounding fuel storage tanks. The medium effectively suppresses flame heights and spread rates in pool fires in said diked areas. The containment medium comprises a mineral aggregate mixed with a flame-effects modifier such as fragments of expanded metal net made from magnesium alloy foil. In a preferred embodiment, the aggregate is sand or gravel, and the flame-effects modifier comprises ellipsoids formed from expanded metal sheets made from magnesium alloy foil.

  • Patent number: 5500037
    Abstract: A highly efficient impact absorber for protecting articles against destructive mechanical impact. The invention has special applicability to containers for flammable materials, scientific instruments, or other fragile mechanisms or articles which may be damaged or become hazardous when ruptured. The impact absorber includes a layer or layers of expanded metal net made from magnesium alloy foil having a thickness in the range from about 0.02 to 0.50 mm. A preferred embodiment utilizes a contained layer or layers of nested spheroids formed from expanded metal sheets made from magnesium foil.

  • Patent number: 5297416
    Abstract: A method of producing an ellipsoid form from an expanded metal foil net teaches the steps of placing a sheet of expanded metal net on a work surface adjacent an open-ended hollow cylinder having the interior shape of a semi-ellipsoid, moving a first piston having the exterior shape of a semi-ellipsoid against the expanded metal sheet and into said open-ended cylinder to form the sheet into a semi-ellipsoid piece having a closed end and an open end, and subsequently moving a second piston into the open-ended cylinder to close the open end of the semi-ellipsoid piece and thus complete formation of the ellipsoid form. The metal foil may be a continuous sheet transversely slip and fed in unstretched form from a roll to the edge of said work surface, then stretched across the work surface and detached from the continuous sheet to provide the expanded metal net sheet to be formed into an ellipsoid.
