    Abstract: Mobile fire-fighting systems and a method of producing breathable fire-suppression compositions are provided for extinguishing fires in buildings, and other human occupied structures, being also effective in suppressing fires under ruins of collapsed buildings. The systems employ a transportable high-pressure container having the breathable composition or nitrogen gas, or a liquid nitrogen container, vaporizer and a mixing chamber, wherein a vaporized nitrogen gas is mixed with an ambient air in order to produce said breathable fire-suppression composition. Refilling stations are provided for refilling the mobile systems with said composition, nitrogen gas or liquid nitrogen, all being generated at site from the ambient air. The method of producing said composition at a fire site employs mixing of nitrogen gas with ambient air or, alternatively, vaporizing of liquid nitrogen in necessary quantities and mixing it with ambient air in provided proportions. A method of delivery of the breathable fire-suppressive composition inside a building on fire is provided as well. The systems are also suitable for installation as a stationary fire-suppression system for a building or other structure. A breathable fire-suppression composition is provided for use in said mobile systems, said composition having an oxygen content below 16% or from 10% to 12% for the majority of civil applications.

    Abstract: A cryogen supply system for supplying either gaseous state cryogen or liquid state cryogen. The cryogen supply system includes a thermally insulated fluid container for holding a volume of cryogenic liquid. A gas inlet port is formed in the fluid container so that gas from an external source can be introduced therein. Inside the fluid container is a cooling module having a gas inlet opening for receiving gas introduced into the fluid container. The gas that flows into the gas inlet opening flows into a heat exchanger located at the base of the fluid container. The heat exchanger is connected to a manifold that, in turn, is connected to an outlet line. A liquid inlet line, having a liquid inlet opening in the base of the fluid container is also connected to the manifold. Gas flow from the heat exchanger to the manifold and from the liquid intake to the manifold is controlled by appropriate valve means. The outlet line is connected to a heating module in which the fluid flowing through may be heated to a selected temperature. The pressure of the gas introduced into the fluid container forces gas into the inlet line and the heat exchanger, where it is cooled to a temperature at or just above that of the cryogenic liquid, and also forces cryogenic liquid into the liquid inlet line.
