The method of the invention comprises the steps of proportioning a foam concentrate into a non-flammable liquid to form a foam concentrate / liquid mixture and creating a flowing stream of the foam concentrate / liquid mixture. Nitrogen is introduced into the stream of the foam / liquid mixture to initiate the formation of a nitrogen expanded foam fire suppressant. In one embodiment the nitrogen is chilled below ambient temperature. The flowing stream carrying the initially nitrogen expanded foam is dispensed, which completes the full expansion of the nitrogen expanded foam fire suppressant, into the confined area involved in fire thereby to smother the fire and to substantially close off contact between combustible material involved in fire and the ambient atmosphere substantially reducing the danger of explosion or flash fires. The system for creating and dispensing the nitrogen expanded foam can be self-contained and includes a proportioner, a source of foam concentrate, a source of nitrogen and a dispenser for completing the extension and dispensing of the nitrogen expanded foam. A chiller can be included to chill the nitrogen below ambient temperature. Optionally a power generator can be incorporated into the system in instances where power is not available. The apparatus for expanding and dispensing foam comprises a housing defining an interior through which extends a discharge line. The ends of the housing are closed about the ends of the discharge line and the ends of the discharge line extend beyond the ends of the housing to define a connector at one end for receiving a stream of foam concentrate / liquid and at the opposite end to define the foam dispensing end of the apparatus. A portion of the discharge line in the housing defines an eductor for introduction of the expanding gas into the stream of foam concentrate / liquid flowing through the discharge line.

The present invention relates to a fire extinguishing product which consists of clean gas extinguishing agent and fire foam and uses clean gas as vesicant and a manufacturing method and a fire extinguishing system thereof. A gas foam fire extinguishing product consisting of the clean gas extinguishing agent and the fire foam uses the clean gas extinguishing agent as a foaming medium of the fir foam. A foam liquid supply device is communicated with a gas foam mixer by a pipeline. The clean gas extinguishing agent is communicated with the gas foam mixer by the pipeline. The gas foam mixer outlet is communicated with a foam generator by the pipeline. The present invention has the advantages of solving the problem that flammable liquid with low boiling point is difficult for extinguishing fire and solving the technical problem that people want to solve but do not solve for a long time.

An improved fuel tank and method of forming a fuel tank utilize reinforced porous metal composite materials. In one embodiment, the composite material includes a fully dense, fluid-impermeable skin combined with a porous metal baffle. The skin and baffle may be formed as a single monolithic system via electrodeposition of a nanolaminate material into at least a portion of open, accessible void space within a porous preform (e.g., a metal foam preform) and on the exterior surface of the preform to form the fluid-impermeable skin.

A process for producing a separator-electrolyte layer for use in a lithium battery, comprising: (a) providing a porous separator; (b) providing a quasi-solid electrolyte containing a lithium salt dissolved in a first liquid solvent up to a first concentration no less than 3 M; and (c) coating or impregnating the separator with the electrolyte to obtain the separator-electrolyte layer with a final concentration≧the first concentration so that the electrolyte exhibits a vapor pressure less than 0.01 kPa when measured at 20° C., a vapor pressure less than 60% of that of the first liquid solvent alone, a flash point at least 20 degrees Celsius higher than a flash point of the first liquid solvent alone, a flash point higher than 150° C., or no detectable flash point. A battery using such a separator-electrolyte is non-flammable and safe, has a long cycle life, high capacity, and high energy density.
