Patent number: 6156088Abstract: A smoke and odor purifying system which can be incorporated within a housing that can serve both as a table centerpiece and an ashtray. The system having an esthetically pleasing flower vase construction with petal shaped appendages for resting of cigarettes or the like. A floral arrangement is made up of individual artificial flowers. Each flower having an opening in the bud for drawing in smoke-filled air and passing it through the system. Also defined within the petals of the housing are a plurality of intake openings through which cigarette smoke, as well as secondary smoke from the surrounding area may be drawn downwardly through the device. An electrically or battery powered fan means, positioned below a filtration and odor-treatment system, drives the smoke through the system which includes an electrostatic prefiltering bed followed by an activated charcoal bed, an H.E.P.A. filter and finally another activated charcoal bed containing an air freshening material.Type: GrantFiled: April 9, 1999Date of Patent: December 5, 2000Inventor: Venanzio Cardarelli

Patent number: 5935525Abstract: An air abatement system that includes a pre-treatment system and an air treatment system for abatement of contaminated air that includes pollutants such as V.O.C.s, NOx, and/or CO. The air stream is treated using activated air, activated water, and ultraviolet light under conditions that produce hyroxyls, peroxides, and other oxidants without the formation of ozone. These oxidants are also utilized in the activated air, with the activated water being formed as an aqueous solution of the activated air. The pre-treatment system includes a quenching zone where activated water is misted into the air stream, followed by alternating reaction zones and depletion zones where activated air is added and then turbulently mixed with the air stream. The air treatment system includes a primary treatment tunnel, carbon bed system, activated air generator, and a sparger tank farm. Activated air produced by the generator as added into water while being exposed to ultraviolet light in the sparger tank farm.Type: GrantFiled: November 1, 1996Date of Patent: August 10, 1999Assignee: Tri-Mark CorporationInventors: Phillip A.
