  • Patent number: 7850766
    Abstract: Systems and methods are provided for substantially reducing undesired cumulative effects by preferentially heating the active particles. By preferentially heating the active particles, the active particles are “cleaned” of substances that may reduce or negate particle activity. In addition, preferential heating may reduce active particle adsorption of binder.

  • Patent number: 7846228
    Abstract: Extraction devices are disclosed for extracting liquid particulates from a gaseous stream. The extraction devices may have a powered or free spinning rotating extractor that may be mounted in the extraction device's source or extraction duct. During operation, liquid particulates impinging on the rotating extractor form a thin film of extracted liquid that travels due to centrifugal force to the periphery of the extractor's exterior surface where the extracted liquid may be flung to the inner surface of the extraction duct and collected.

  • Patent number: 7837752
    Abstract: A rigid or semi-rigid demister pad is positioned between an air turbine and an inertial water removal device such as extractor in an air conditioning system for an aircraft. The demister pad comprises packed fibers or strands whose diameter typically ranges from approximately 10 or fewer microns to approximately 280 microns. The demister is capable of catching very small droplets discharged from the air turbine that coalesce into larger droplets that exit the demister pad and enter an adjacent water removal device downstream from the pad to separate the larger water droplets from the stream of air. This avoids using a water separator containing a coalescer bag that requires frequent maintenance and is sensitive to dirt and freezing. The demister can operate at freezing temperature, is not dirt-sensitive and requires no maintenance.

  • Patent number: 7833301
    Abstract: A diffuser for a work machine having an air breathing fuel consuming internal combustion engine with an exhaust aftertreatment device periodically elevating the exhaust temperatures to a high level. The diffuser has a venturi section and the excess contaminants from an intake air pre-cleaner are directed to the throat of the venturi to aspirate and dispose of excess contaminants while cooling the exhaust flow. Additional openings in the divergent section of the diffuser assist in providing significant reductions in exhaust temperatures within a short axial envelope.

  • Patent number: 7828867
    Abstract: A portable air treatment device and system including a filter retaining mechanism for selectively retaining a replaceable filter assembly. The filter retaining mechanism includes a rigid, non-moveable body that reduces a size of an access opening to a filter chamber otherwise formed by the air treatment device housing, along with a bearing surface. The rigid body serves as a catch or latch, preventing unexpected dislodgement of a filter assembly from the chamber. The bearing surface is also rigid and non-moveable, and provides a means for easily inserting and removing a primarily non-permanently deflectable filter assembly about the rigid body.

  • Patent number: 7824457
    Abstract: A portable dust collector for woodshop or other use with portable tools has a conic body that is supported on a tripod carriage formed of three legs attaching to gussets at the sides of the conic body. A divider plate within the conic body divides it into a cyclonic chamber between the divider plate and the lower nose, and a fan chamber between the divider plate and a motor plate that closes the upper mouth of the conic body. A final filter cartridge is fitted onto the outlet pipe, so that the dust collector exhausts clean, filtered air into the ambient. The final filter may be supported from a 90-degree elbow, with a removable tray for catching process dust that is knocked off the interior of the filter.
