Abstract:
A method and apparatus for inhibiting or preventing fouling of open-cell reticulate foams which are made of a material such as polyurethane or the like and which are used as inserts in aircraft fuel tanks. The micro-organisms present in turbine aircraft fuel such as kerosene can produce a gellike contaminant which rapidly forms in the cellular structure of open-cell foams and can completely fill or clog such structure, thus diminishing the fuel-carrying capacity of the tank and adding unwanted weight to the aircraft. The formation and adhesion of micro-organism growth in open-cell foams is eliminated or materially reduced by providing a foam incorporating a systemic toxin such as an acid addition salt of rosaniline. Dyes generally known as ''''Brilliant green'''' or ''''Malachite green'''' are suitable for use as such systemic toxins.
Abstract:
COMPOSITIONS ARE DISCLOSED WHICH FORM TOUGH, DURABLE, RAPIDLY-FORMING AND SPREADING FILMS ON THE SURFACE OF HYDROCARBON LIQUIDS COMPRISING IN COMBINATION A WATERSOLUBLE FLUOROALIPHATIC SURFACTANT AND A WATER-SOLUBLE SYNTHETIC IMPUTRESCIBLE HYDROCARBON-CONGRUOUS ORGANIC FLUORINE-FREE SURFACTANT AND WATER. THE FILMS FORMED BY THESE COMPOSITIONS ARE ESPECIALLY EFFECTIVE IN SUPPRESSING THE VAPORIZATION OF HYDROCARBON LIQUIDS INTO THE AIR AND ARE, THEREFORE, USEFUL FOR EXTINGUISHING LIQUID HYDROCARBON FIRES.
Abstract:
The present invention is directed to vapor suppression of liquids through disposing a layer of surfactant onto the surfaces of liquids for surfactants having a density greater than the liquid and regardless of surface tension spreadability issues, and compositions comprising the surfactants in aerosolized form.
Abstract:
Изобретение относится к области энергетики и может быть использовано как топливная энергетическая система движущей силы. Предложена энергетическая система движущей силы альтернативного, универсального, перспективного, безуглеродного, беспламенного топлива на основе водного раствора нитрата и/или нитрита аммония или их смеси, в котором нитрат и/или нитрит аммония взяты в количестве, обеспечивающем при их разложении выделение энергии для образования парогазовой смеси высокого давления для совершения работы, или слабопламенного - при внесении в состав топлива дополнительно органических веществ, образующих стабильные, гомогенные растворы.
Abstract:
A method, a system, and a non-transitory computer-readable medium for controlling flammability of a fuel. The method includes applying a voltage across a nonvolatile ionic liquid to convert the nonvolatile ionic liquid into a flammable liquid; and removing the applied voltage across the nonvolatile ionic liquid to revert the flammable liquid back to the nonvolatile ionic liquid.
Abstract:
A POLYMERIC CARBOHYDRATE DERIVATIVE SUCH AS CELLULOSE LAURATE OR STARCH LAURATE WITH A PERCENTAGE OF SUBSTITUTION BETWEEN ABOUT 40% AND ABOUT 100% IS DISPERSED OR DISSOLVED IN JET FUEL OR OTHER HYDROCARBON OR NONPOLAR SOLVENT AT A CONCENTRATION OF AT LEAST ABOUT 0.5 GRAM SOLIDS/100 ML. FLUID. THE GELLED JET FUEL IS HELPFUL IN AVOIDING FIRES IN AIRCRAFT ACCIDENTS.
