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:
An energy system may use an alternative, universal, promising, carbon-free, flameless fuel, based on an aqueous solution of ammonium nitrate and/or nitrite or mixtures thereof, wherein the ammonium nitrate and/or nitrite are used in amounts providing, upon their decomposition, a release of energy for forming high pressure vapor-gas mixture to perform work. Upon introduction of organic substances to the fuel composition, stable, homogeneous solutions may be formed also useful as fuel. An engine may perform work by initiating a reaction in on the fuel to expand a gas or fluid within an internal combustion engine or the like.
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.
