Abstract: An air tight sealing cuff for a blast gate includes a pair of flat plates disposed on opposite sides of the slide mounting of the gate, and replaceable spring clips for holding the plates in position. Resilient gasket material applied to the plates forms a substantially air-tight seal between the slider and slide mount of the cuff and the exterior of the cuff. As a consequence, there is eliminated inadvertent leakage from the area around the gate slider, which would otherwise represent wasted energy. Improved efficiency and reduced carbon footprint result.

Abstract: An air conditioner of present invention comprises a housing having an outer panel forming the exterior and an opening formed on the outer panel, a heat exchanger configured to exchange heat with air flowing into the housing, and a door unit configured to open or close the opening by moving forward or backward from the opening through which the heat exchanged air is discharged. Wherein the door unit comprises a door blade configured to open or close the opening, a door operating part configured to move the door blade forward or backward, and a controller configured to control the air discharged from the opening to be moved forward from the opening in a straight line or to be discharged radially from the opening by controlling a distance between the door blade and the opening.

Abstract: A ceiling vent assembly consisting of a pair of opposed end panels and a pair of opposed side panels which defining a frame. At least one louver is pivotally mounted within the frame to be movable between an open position to permit airflow through the vent assembly and a closed position blocking airflow. The louver includes an upper surface defining a curvature and decreases in thickness at an outer edge. When in an open configuration, the louver permits air to pass through the ceiling vent assembly in a directed flow associated with the curvature of the louver upper surface.

Abstract: A device for an air handling system in which the cooling beam has a pressure chamber (2), from which the volume flow of the supply air (L1) out to the room is regulated with a regulating strip (6) that is mounted on the surfaces (9) in the pressure chamber and where the flow of the supply air (L1), in the mixing chamber (4), provides an optimal flow pattern of the recirculating air (L2) from the room and where the combined flow of supply air (L1) and recirculating air (L2) acquire well defined flow profiles independent from the volume flow (L1).

Abstract: A vent hood and flashing assembly for use on a metal roof. A vent hood overlies and is joined to flashing. A cover and a screen overlie an upper end portion of the flashing to exclude rain, snow and pests. The flashing includes a resilient, flexible, water-repellant, flexible flange that extends outward from, and is attached to, a lower end portion of the flashing and a flexible, ring seal that overlies an upper surface of the flange. The assembly can be placed over a projection through an opening in a metal roof such that the cover and screen overlie an upper end of the projection and with the flashing surrounding the projection, and the flange can be bent to sealingly conform to the roof surface and secured thereto by fasteners.

Abstract: A room humidifying assembly (20) is provided which is easily and quickly installed, is simple to operate, and is a cost effective means for maintaining a comfortable humidity level in a room. The room humidifying assembly (20) preferably includes a body (22), adapted for positioning within a ventilation duct (24) adjacent a duct outlet (26), and a wick (32) having a first section (34) and a second section (36). The body (22) includes a reservoir (28) adapted to hold a supply of water, and the second section (36) of the wick (32) is disposed within the reservoir (28) in contact with the water therein. The first section (34) of the wick (32) is supported across at least a portion of the duct (24) by an apertured frame (30) secured to the body (22) to permit the passage of ventilating air through the first section (34). The wick (32) is configured for delivery of water from the second section (36) to the first section (34) by capillary attraction.

Abstract: An energy saving cover for use in a building having an opening in a ceiling with an attic fan thereabove, the building having a voltage source, the cover including a horizontal frame attachable to the ceiling below the attic fan opening, a cover panel slidable within the frame between a closed position in which the attic fan is fully covered to substantially reduce the passage of air therethrough and an open position in which the attic fan opening is fully opened, and a switch supported to the frame having an "on" and "off" condition and positioned such that the switch is actuated to the "on" position when the cover is in the fully opened position, the switch being in series with the attic fan motor so that the attic fan motor can be energized only when the cover is in the fully opened position.
