  • Patent number: 4177863
    Abstract: An improved inflammable liquid safety tank comprising a double walled tank body with the tank walls being interconnected by support plates. An intermediate container is formed by the inner wall structure of the tank and is adapted to hold inflammable liquid. A pressurized gas bottle is threadably mounted to a sleeve secured to and extending into the intermediate container. The pressurized gas bottle is selectively connected to the intermediate container to pressurize liquid held in the intermediate container. The pressurized gas bottle also communicates with the tank to pressurize a foam, nonflammable fluid, or cleaning agent placed in the chamber or outer compartment defined by the outer wall structure of the intermediate container and the inner wall structure of the tank body so that the foam, fluid or agent will be expelled from the tank if the tank wall is accidentally punctured. The outer compartment is preferably pressurized at a lower pressure than the intermediate container.

  • Patent number: 4174711
    Abstract: In the walls of a fire resistant enclosure such as a cabinet for storing heat sensitive, valuable goods or a room or shelter in a building in which persons can find refuge in the event of a fire, hollow bodies of large area contain substances which melt at a temperature which is still acceptable to the contents of the cabinet or physiologically acceptable to the persons in the room or shelter. The invention also provides various appliances for alleviating conditions in a said room or shelter, for providing a breathing air supply at an acceptable temperature for persons trapped therein and for facilitating the evacuation of persons therefrom, all such appliances involving the use of substances adapted to absorb heat from their environment by utilizing the latent heat of fusion of the substances.

  • Patent number: 4172573
    Abstract: An external, aircraft fuel tank constructed to be crashworthy or to withstand a crash from flight without rupturing the outer, rigid walls thereof. The fuel tank includes bulkheads arranged in the tank adjacent to but spaced from the end sections and defined to be yieldably responsive to fluid pressures above normal operating pressures for dissipating the kinetic energy of the fluid without rupturing the outer, rigid walls of the tank.
