Abstract: An apparatus improves the efficiency and emissions of a combustion process by producing sufficient amounts of ozone in the air flow to the combustion chamber to enable more complete and cleaner combustion of the fuel. The apparatus may include a plurality of cell elements disposed within a housing that is in placed in the air intake to a combustion chamber such as a diesel engine. The cell elements create an electrical plasma field that produces ozone. The apparatus may also include a scrubber in the housing to cause the air flow to have a vortex action to increase the amount of ozone that flows into the combustion chamber.

Abstract: A process for the preparation of an inorganic filler material coated with a nano-particulate tin compound which comprises forming a slurry of the filler material in an aqueous colloidal suspension of a tin compound, whereby the tin compound is directly precipitated from the colloidal suspension onto the surface of the filler, separating the inorganic filler from the colloidal suspension and, optionally, heating the coated filler to convert the hydrated tin compound to the anhydrous form. A fire retardant material comprises a particulate inorganic material coated with a nano-particulate tin product in an amount of from 1 to 100% by weight, based on the weight of the inorganic filler.
