Abstract: A photocatalytic odor control device includes an air passageway defined between an air inlet and an air outlet and configured to conduct and direct air flow, a photocatalytic plate disposed within the air passageway, the photocatalytic plate having a titanium dioxide coating incorporating metal oxide ion dopants on the surface of the plate, and a light source configured to emit an ultraviolet light onto the photocatalytic plate, the emitted ultraviolet light having a predetermined wavelength sufficient to trigger a photocatalytic reaction to generate hydroxyl free radicals and reactive oxygen species to neutralize organic compounds in the air flow.

Abstract: The method of capturing gaseous heavy metals disclosed herein includes exposing a stream of vapor including the gaseous heavy metals to a reactor bed of carbon (C) and aluminum (Al) in the form of pellets and granules. The gaseous heavy metals include mercury (Hg), mercury oxide (HgxOy), and other heavy metals in ionized or oxidized form.

Abstract: The VOC disposal system disclosed herein includes a plasma chamber and a vent chamber. The plasma chamber includes one or more bands of plasma igniters that produce a field of free radicals across a volume of the plasma chamber. Volatile Organic Compounds (VOCs) are introduced to the plasma chamber and react with the free radicals, breaking down the VOCs into component parts as the materials travel from the plasma chamber to the vent chamber.

Abstract: The waste disposal system disclosed herein includes a chamber operated at high ampere and low voltage, the chamber configured to inject smoke on a stream of free radicals. In one implementation, the stream of free radicals is generated from a plasma igniter and the smoke is generated from waste products, such as hospital waste products.

Abstract: Glycerin-containing explosive compositions comprising at least an oxidizer and glycerin are provided. The explosive compositions may comprise a glycerin, such as impure or crude glycerin, modified crude glycerin, substantially pure glycerin or pure glycerin. The explosive compositions may comprise other combustible fuels such as fuel oil or carbonaceous material(s). The explosive compositions may be prepared on site, loaded in bulk on mobile platforms, and/or prepared and packaged in suitable containers.

Abstract: A buffered emulsion blasting agent is disclosed, particularly suited for use in connection with sulfide and pyrite ores. The buffered emulsion blasting agent comprises an emulsifier, an organic fuel in continuous phase, an oxidizer salt solution in discontinuous phase, and a buffering agent comprising a low molecular weight amine. The low molecular weight amine is preferably an alkylamine or alkanolamine having carbon chain lengths of from 2 to 5 and is more preferably diethanolamine. The buffering agent is present in the buffered emulsion blasting agent in a weight percent that is preferably within a range of from approximately 0.1% to 5%, more preferably within a range of from approximately 0.5% to 1%, and most preferably approximately 0.75%.

Abstract: A stemming agent is provided comprising: A) a neutralized acrylic acid polymer; B) a neutralized mixture of sodium silicate and a silicon oxide-containing material such as sand, clay, stones, volcanic ash, or the like; or C) a mixture of materials A) and B). The stemming agents produced are low cost, easily made, and preferably are free of nitrate salts. Accordingly, the use of these preferred stemming agents eliminates the contamination of ground water by nitrate salts. The stemming agents of the invention may be used in either bulk-delivered or packaged applications.

Abstract: The present invention is directed to a sensitizer provided as a foam that may be used individually and/or added to explosives, propellants, and/or pyrotechnics.

Abstract: The present invention is directed to intimately combining petroleum products with ammonium nitrate prills forming a coating thereon, whereby said coating is tackified and free flowing.

Abstract: A method for producing an emulsion explosive comprises introducing a liquid organic fuel phase and an immiscible liquid oxidizer phase into apparatus having a mixer chamber, flow constrictor means for introducing the liquid oxidizer phase as an emergent turbulent jet into the chamber to cause its fragmentation into droplets in situ within the chamber, means for introducing the fuel phase into the chamber so that the fuel phase introduced thereby contacts and becomes distributed around the droplets of oxidizer phase as they form to produce emulsion and further providing shear mixing means within the mixing chamber to effect enhancement of the mixing of the chamber contents and thereby to continuously incorporate the fuel phase to produce a more refined emulsion suitable for use as the basis for an explosive system, particularly emulsions of high velocity.

Abstract: Apparatus for producing a multi-phase emulsion explosive from a liquid organic fuel medium and an immiscible liquid oxidizer comprises a mixing chamber, flow constrictor means for introducing the liquid oxidizer as an emergent turbulent jet to said chamber and causing formation of droplets of said oxidizer in situ within the chamber, means for introducing the fuel medium to said chamber so that the fuel introduced thereby contacts and stabilizes the droplets of oxidizer solution as they are formed to maintain same as discrete droplets of oxidizer liquid and thereby provide an emulsion suitable for use as the basis for an explosive system.

Abstract: A packaged booster charge is provided which is sensitive to initiation by blasting cap yet which contains no self-explosive ingredient. The composition of the booster comprises a low melting point nitrate salt or salt mixture having dissolved or finely dispersed therein an acetylenic substance and void containing material. The booster is safe and economic to manufacture and sufficiently powerful to initiate insensitive blasting agents.

Abstract: An emulsion explosive composition comprising an oxygen-supplying salt component as a discontinuous phase, an organic medium forming a continuous phase and an emulsifying agent which comprises at least one conventional emulsifier and at least one emulsification enhancer. The compositions are easily emulsifiable.
