Abstract:
A fuel gas composition which comprises essentially a mixture gas of 65-90 volume percent of acetylene and 35-10 volume percent of LP gas, the mixture of gas being dispersed in a high pressure container which is packed with a porous material permeated with a solvent or solvents selected from a group consisting of acetone, toluene and xylene. The composition is found to be safely storable, transportable and usable under high pressure, has relatively constant composition upon withdrawal from storage, and effective in welding or torch cutting.
Abstract:
DECREASING THE VISCOSITY OF AND IMPROVING THE ATOMIZING AND BURNING CHARACTERISTICS OF A HEAVY HYDROCARBON BY DISSOLVING A NON-HYDROCARBON GAS IN THE HEAVY HYDROCARBON IN AN AMOUNT NOT EXCEEDING 95% OF SATURATION AT CONDITIONS OF TEMPERATURE AND PRESSURE IMMEDIATELY PRECEDING ATOMIZATION
Abstract:
A FRACTIONAL DISTILLATION COLUMN OPERATING AS A GASOLINE SPLITTER IS CONTROLLED BY MEASURING THE OCTANE NUMBER OF THE COLUMN OVERHEAD FRACTION AND ADJUSTING THE REFLUX TO THE COLUMN IN RESPONSE TO THE OCTANE NUMBER. THE OCTANE MEASUREMENT IS EFFECTED BY AN ANALYZER COMPRISING A STABILIZED COOL FLAME GENERATOR WITH SERVO-POSITIONED FLAME FRONT WHICH PROVIDES A REAL TIME OUTPUT SIGNAL INDICATIVE OF SAMPLE OCTANE NUMBER.
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.
