Abstract: The decontamination of birds and other animals, the victims of oil spills by adding a low viscosity oil, by means of agitated tanks or sprays, to fur or feathers as a diluent followed by a water in oil emulsion, which is then inverted to an oil in water emulsion. The contaminants are thus in the internal phase and the external phase is aqueous. The remaining contaminants are then washed away with water.

Abstract: A lubricating composition of essentially only a lubricating oil and particles of polytetrafluoroethylene uniformly dispersed and suspended in the lubricating oil. The lubricating composition is manufactured by sonically agitating a mixture of lubricating oil and particles of polytetrafluoroethylene at sufficiently high energy levels to produce violent cavitation. The sonic agitation is provided by an ultrasonic generating device in a system whereby the mixture is sonically agitated as it continuously passes through the ultrasonic generator.

Abstract: A fuel supply system is disclosed in which oil and water are mixed and delivered under pressure to a nozzle or other atomizing means at which combustion is to occur. The mixture of oil and water is delivered to the atomizing means along conduit means and those conduit means include means to produce agitation of the oil and water so that an intimate mixture of oil and water is delivered to the atomizing means. Complete emulsification occurs at the atomizing means to promote combustion.

Abstract: A stable fuel emulsion comprising water, coal and an oil component comprising a distillate oil and a residual oil stabilizing ingredient. The stable fuel is produced by forming a water/coal slurry, blending the distillate oil and stabilizing residual oil together, combining the slurry and oil blend and agitating the mixture.Further, a stable fuel emulsion comprising essentially only water and oil wherein the oil is comprised of a distillate oil component and a residual oil stabilizing ingredient. The stable fuel is produced by blending the distillate oil and the stabilizing residual oil together, combining the resulting blend with water and agitating the mixture.

Abstract: The production of fuel comprising an emulsion of coal particles, oil and water or a dispersion of coal and oil in which pyrites, ash and other impurities are removed from the coal particles and the particles reduced in size by forming a slurry of contaminated coal particles and water and exposing that slurry to violent sonic agitation to cause the impurities to be detached from the coal particles and the particles to be reduced in size. The coal and impurities are thereafter separated and the coal subsequently incorporated into a fuel. The process may also be used to separate other minerals which are bonded mechanically as distinct from chemically, to each other.

Abstract: A coal slurry containing 10-60% solids by weight is optionally first coarsely ground to about 20-80 mesh. Contaminant matter released thereby, may be separated by conventional means such as froth flotation which would eliminate a large proportion of the ash which is energy consuming as well as abrasive in nature. The "clean slurry" would now have water added back and would be further ground to about 100-300 mesh particle size and would then be cavitated by sonic energy making the particle size even smaller and freeing any remaining contaminants including iron pyrites and ash. To this, a mixture of oil is added and the coal, oil mixture is then sonified during which process spherical agglomeration of the coal and oil occurs. The agglomerate and water mixture is screened to separate out most of the water leaving behind about 10-40% water in the coal, during which process the contaminants are also discharged with the water. The spherical agglomerates are mixed with a balance of oil to about 0.

Abstract: A fuel supply system comprises a supply tank with a main fuel conduit leading to a combustion zone, such as an internal combustion engine, and a secondary fuel conduit with flow restriction means is provided leading from the lowermost region of the tank to rejoin the main fuel conduit prior to the combustion zone so that any water accumulating in the tank is mixed with fuel to be burned at the combustion zone.

Abstract: Apparatus and method for producing a fuel comprised of oil and water in which a mixture of oil and water is constituted as an emulsion by exposure to agitation effective to cause cavitation within the mixture.
