The present invention provides combined property, dual-action aqueous and dry compositions for application to a material, such as conventional Gypsum Wall Board, ceiling tiles, joint compounds, concrete and other interior building materials, prior to an exposure of the material to fire, or prior to, during or after exposure of the material to conditions favorable to the growth of microbes, and related methods. When compositions within the present invention are properly applied to a material prior to the material being exposed to fire, or prior to, during or after the material being exposed to conditions favorable to the growth of microbes, these compositions have the effect of reducing the amount of burning that occurs to the material, and/or reducing the amount or density of smoke and associated toxic gases produced by the material, when the material is exposed to fire. These compositions also have the effect of inhibiting or reducing the growth, build-up or deposit of microbes on the material when the material is exposed to conditions favorable to the growth of microbes.

Aqueous and dry duel-action flame and smoke retardant and microbe inhibiting compositions, and related methods

The present invention provides compositions for application to a material, such as building materials, prior to an exposure of the material to fire, or prior to, during or after exposure of the material to conditions favorable to the growth of microbes. When compositions within the present invention are properly applied to a material, they have the effect of reducing the amount of burning that occurs to the material, and/or reducing the amount or density of smoke and associated toxic gases produced by the material, when the material is exposed to fire, and inhibiting the growth of microbes on the material when the material is exposed to conditions favorable to the growth of microbes. The invention also provides methods for reducing the burning of a material that is exposed to fire, and for inhibiting the growth of microbes on a material exposed to conditions favorable to the growth of microbes.

Flame retardant and microbe inhibiting methods and compositions

An extruder and methods for converting pressurized liquid CO.sub.2 feed into dry ice pellets of predetermined shape and size, wherein the CO.sub.2 snow formation, CO.sub.2 snow compaction, and dry ice pellet extrusion phases occur simultaneously to achieve production rates on the order of 700-1000 lbs/hr. The increased production rates are achieved utilizing sintered plastic filter media to provide enhanced removal of CO.sub.2 gas from the CO.sub.2 snow formation chamber.

Pellet extruding machine

An extruder for converting pressurized liquid CO.sub.2 feed into dry ice pellets of predetermined shape and size, wherein the CO.sub.2 snow formation, CO.sub.2 snow compaction, and dry ice pellet extrusion phases occur simultaneously to achieve production rates on the order of 700-1000 lbs/hr. The compacted CO.sub.2 snow may be in the form of a solid cartridge or irregularly shaped solids, and such compacted particles may constitute an end product by themselves. The increased production rates are also achieved by enhanced removal of CO.sub.2 gas from the CO.sub.2 snow formation chamber, and use of a bidirectional internal regeneration cylinder to provide compactive force. The extruder is portable, since it only weighs approximately 1000 lbs., can be powered with a non-stationary energy source, and may be used to remanufacture partially sublimated dry ice solids into extruded dry ice pellets of a predetermined shape and size.

An amplified mixer-blower device for discharging a feed material at high velocity and enhanced volume using a venturi transport principle. Preferably, carbon dioxide vapor is used as a means for propelling the feed material which may have a different phase of the same composition of the propulsive gas, or constitute an entirely different material. The apparatus is suitable for a number of applications such as neutralizing airborne ammonia vapor or droplets, extinguishing a flammable liquid, and conveying solid materials.

Amplified mixer-blower mechanism and uses thereof

A fire extinguishing composition including potassium carbonate, a boron-containing compound, and water. In another embodiment, the fire extinguishing composition, in addition to the above, includes a potassium salt of an organic acid having from 1 to 6 carbon atoms. The fire extinguishing composition is non-corrosive to metals.
