Abstract: A livestock facility exhaust system to remove a majority of the dust and other such odorous airborne particulate material from air exhausted by power ventilation equipment from a livestock confinement building and without a significant increase in static pressure within the ventilation system. This is accomplished by a free standing enclosure of high strength air permeable material supported by a hoop structure around the exhaust end of the containment building of the livestock facility. Exhausted air enters the enclosure and is temporarily contained therein. Air circulates around impaction surfaces in the enclosure that promote precipitation of airborne particulates from the air stream. A discharge opening is located at or near the top of the enclosure. Exhaust air rid of most of the airborne particulates moves upward and out through the opening. The enclosure also serves to deflect outside wind from the fan orifices which helps to maintain fan performance.

Abstract: In a vehicle air conditioner, an air conditioning case has a front air passage and a rear air passage through which air is blown to a front seat side and a rear seat side in a passenger compartment, respectively. The air conditioner includes an air-blowing amount determination unit for determining an air-blowing amount of a blower, and a correction unit for increasing the air-blowing amount determined by the determination unit when the rear air passage is opened. The correction unit increases an increase amount of the air-blowing amount to be larger in a face mode, than that in a bi-level mode.

Abstract: Air vent for protecting the public potable water system against terrorism and sabotage. Conventional air vents allow the movement of air in and out of an enclosed reservoir structure but do not stop the penetration of liquids or solids. The present invention allows the movement of air but will not allow any liquids or solids to pass through the vent, even if these liquids or solids are being applied under pressure. This is accomplished by an energy dissipating arrangement of S-shape structural members.

The inductors are generally arranged in a square configuration with the diffuser extending in the square space bound thereby.

Abstract: A fabric air duct with main discharge openings includes additional, much smaller openings that help ventilate the surface of the duct. Ventilating the surface of the duct with a slight yet even amount of airflow helps inhibit the accumulation of condensate and dust on the surface of the duct. In some embodiments, the duct includes a pliable sheet consisting of a rather porous fabric base material. To achieve an appropriately low level of airflow, a plastic coating on the fabric reduces, but does not eliminate the fabric's porosity. A calendering process then reduces the porosity even further. In other embodiments, the pliable sheet is substantially air impermeable, except for its main discharge openings. The sheet is then perforated with numerous smaller openings to achieve the desired amount of surface ventilation.
