Abstract: A louvered panel assembly restricts the ingress of contaminants into an enclosure. The louvered panel assembly includes a first louvered panel, a second louvered panel, and a third louvered panel. The first louvered panel has a first plurality of louvers extending arcuately, downwardly, and outwardly from a first plate. The second louvered panel is coupled to the first louvered panel and has a second plurality of louvers extending arcuately, downwardly, and inwardly away from a second plate that is spaced apart from the first plate. The third louvered panel is coupled to the second louvered panel and has a third plurality of louvers extending arcuately, upwardly, and inwardly away from a third plate that is spaced apart from and extends approximately parallel to the second plate.

Abstract: A passive cooling system routes air from an enclosure to an ambient environment, via a chimney effect, through one or more indirect pathways and re-directs environmental elements received from the ambient environment. One or more vanes are arranged within an interior space, such that the vanes collectively form one or more indirect pathways to the ambient environment. The vanes preclude environmental elements, including precipitation and particulate matter, from passing through the interior space and into the enclosure. Environmental elements are re-directed by one or more of the vanes, at least in part, to an exterior of the passive exhaust system. Dampers may be adjusted to control airflow through the passive cooling system and restrict environmental elements from entering the passive cooling system. Liquids received from the ambient environment may be re-directed into a reclamation system for use in a cooling system.

Abstract: A generally planar blank made, for example, from sheet metal can be formed into a vent protector that can be mounted to an outer wall of a structure over the exhaust aperture of a vent to inhibit vertebrate wildlife from entering the vent. The vent protector forms an enclosure for receiving vent flaps that may extend outwardly from the wall of the structure.

Abstract: An image forming apparatus according to the present disclosure includes a fan, a first louver, and a second louver. The first louver includes first rectifier vanes that direct airflow produced by the fan. The second louver is located on an inner side of an apparatus body with respect to the first louver and faces the first louver in such a manner as to overlap the first louver in a direction of an axis of rotation of the fan. The second louver includes second rectifier vanes that direct the airflow produced by the fan. Each of the first rectifier vanes and a corresponding one of the second rectifier vanes that is adjacent thereto extend in one plane inclining at a specific angle with respect to the axis of rotation of the fan.

Abstract: A covering apparatus for an enclosure presenting a ventilating barrier curved with respect to a barrier axis includes a segmented panel member having a plurality of louvered areas. Respective adjacent louvered areas of the plurality of louvered areas are separated by a respective bend structure. Each respective bend structure has a first section departing in a first direction from a first bend axis and a second section departing in a second direction from a second bend axis. The first and second bend axes are generally parallel with the barrier axis. The first direction is generally away from the second bend axis. The second direction is generally away from the first bend axis. The bend structure further has a third section extending from the first and second bend axes to a third bend axis. The third bend axis is non-coplanar with the first and second bend axes.

Abstract: Vent apparatus for a building includes a frame within which are positioned two spaced sets of louvers. The louvers of each set of louvers have openings therebetween and the openings of each set of louvers are covered by the louvers of the other set of louvers.

Abstract: A storm louver (10, 12) having a plurality of spaced blades (16a, 16b, 16c, 16d) for removing water particles from air flowing into a building or air handling equipment is disclosed. Each louver (10, 12) has an improved blade support frame (18) that permits the blades (16a, 16b, 16c, 16d) to be more quickly and easily installed in the support frame (18) and that more firmly supports the blades. A modular louver system including at least two individual louvers that can be easily connected for installation in openings of any size is also disclosed.

Abstract: The instant invention is a water resistant louver characterized by an aesthetically pleasing two piece front louver frame affixed to a posteriorally positioned aluminum mesh screen in turn affixed to a spacer frame behind it that encompasses a plurality of horizontally parallel deflector slats affixed to a face plate affixed to the frontal portion of a rear louver frame attached to the screen and front frame via a plurality of fastening screws with all frames and the screen affixed to a positively sloped bottom sill plate, the top side of which is metallically lined to accept water deflected from the slots and a drip cap within the rear louver frame located just behind the lowest of such slats and thereby permit deflected water to run through two identical notches cut into the rear portion of the frontal frame to the outside of the frontal portion of the front frame via two slits in the frontal portion contiguous each with each notch and each of which slits is positioned laterally to a centrally positioned be

Abstract: Disclosed is an air-flow-directing grille assembly of the type having two frame members and a grille bar supported by such frame members for pivoting movement about a grille bar axis. In the improvement, each frame member has a hole, the bar has an axle extending through the holes and each hole and the axle are cooperatively sized to provide a friction fit between such hole and axle. The grille bar is thereby frictionally retained in a position. A new method for making a grille assembly includes providing a pair of frame members, each having a hole therethrough of a first diameter. A grille bar is provided to have an axle with a second diameter at least equal to the first diameter. The axle and the frame member holes are urged into frictional engagement with one another and the grille bars will thereby hold a selected air-flow-directing position.

Abstract: A louver has vertical blades arranged in a frame alternately in a staggered relation from front to back in a front and a rear row. The blades in at least the front row have a web oriented substantially perpendicularly to the plane of the frame and substantially parallel to the jambs, a pair of front flanges extending in opposite directions generally laterally from a front edge of the web, and a pair of rear flanges extending in opposite directions generally laterally from a rear edge of the web. The webs subdivide the air flow volume within the frame into flow channels, each of which is partially blocked laterally by the front flanges and the rear flanges of the blades of the front row. The blades of the rear row have flanges that block the portions of the channels between the extremities of the flanges of the blades of the front row.

Abstract: A ventilator for buildings comprising a cylindrical main body which is open at both ends and provided with a plurality of seating members installed at attachment holes opened in the cylindrical circumferential wall of the main body. The seating members having surfaces conforming to the curvature of the cylindrical main body and also having perpendicular ends for holding the slats securely by screws.
