Abstract: A mist generating system for a cleaning implement is adapted to generate a finely atomized liquid mist for suppressing dust, allergens, and other airborne particulates. The mist generating system can be adapted to fit many cleaning implements such as vacuum cleaners, wet extraction cleaners, floor mops, and dusters to suppress airborne dust and particulates generated during operation and the cleaning process.

Abstract: A modified wet scrubber for removing airborne toner particles including, increased recirculation pumping capacity, and controlling the operating fluid level by relating the pressure differential between the inlet and outlet air streams to proper operating fluid level.

Abstract: Aspects include a valve comprising a flowing liquid, operable to control a flow of gas through a port. Certain aspects include reaction chambers operable to react gases, and in some aspects gases are substantially contained within an envelope comprised of a flowing liquid. Certain embodiments control gas entrance into a chamber with a valve comprised of a flowing liquid controlling gas flow through a port. Various gas scrubbing systems are described, including systems comprising reaction chambers operable to react gases that yield substantial amounts of solid reaction products. Methods for controlling gas flow are disclosed. Systems and methods include sequential steps of wet-scrubbing, reacting and further wet-scrubbing a gas stream.

Abstract: An apparatus for collecting airborne particles includes a cyclone into which external air and an absorbing liquid are sprayed to absorb the airborne particles in the external air with the absorbing liquid, a reservoir in fluid communication with the cyclone and which stores the absorbing liquid to be sprayed into the cyclone as an absorbing liquid film, a collector in fluid communication with the cyclone and which collects the absorbing liquid film from the cyclone, and a feedback pipe in fluid communication with the collector and the reservoir and which transports the absorbing liquid film collected in the collector to the reservoir.

Abstract: There is provided apparatus for treating water containing industrial waste products. A first tank contains water at a determined pressure. A second tank is placed inside the first tank and communicated with a lower portion thereof. It contains water at a lower pressure than that of the first tank. An inlet device of the discharge product is located in the second tank. A first dilution sector of the waste product is external to the tanks but in communication with the second tank at one end and connected to the other end with a Venturi tube and has an outlet duct for waste product diluted by said second tank. The Venturi tube is in communication with the first tank and creates a depression of the second tank with respect to the first tank. The second tank has an internal portion for the dilution of the industrial waste product.

Abstract: An exhaust cleaning device for removing a portion of carbon containing molecules from exhaust. The exhaust cleaning device includes a tubular member which is elongate and has a first end and a second end. The first and second ends are placed in communication with an exhaust system. The tubular member has a middle section and two legs. A cleaning assembly for cleaning the exhaust includes a plurality of apertures extending through the middle section of the tubular member. A housing is attached to an outer surface of the bottom half of the middle section and covers the apertures such that the apertures extend into the housing. A container is extendable into the housing. A filter member is removably positioned in the container. A water pump sprays water into the tubular member such that the water binds to carbon containing molecules in the exhaust and deposits the molecules in the filter.
