Abstract: A passive building vent disposed in an outside vertical building wall, communicates between the outside atmospheric air and the confined air within the building, via a housing forming an air mixing chamber with a passageway disposed therethrough. A movable membrane is mounted within the housing at one end of the passageway, the other end of the passageway communicates with the confined air and is disposed outside of the vertical building wall. The membrane has a closed position, substantially blocking the passageway and an open position, permitting the free flow of air therethrough. The air passage permits the flow of outside air into the air mixing chamber. A venting device communicates with the air mixing chamber permitting the flow of air to exit from the air mixing chamber. A deflector is mounted on the housing proximate the venting device and communicates with the air mixing chamber.

A bleeder mechanism, in the form of a plurality of cords disposed in the chambers keep substantially all of the areas of the chambers in communication with each other so that inflation and more especially deflation, can be readily accomplished without forming air pockets caused by the inner and outer chamber walls sticking together precluding the free flow of air.

Abstract: An automatic temperature responsive damper assembly for use within the conduit of a ventilating system designed to exhaust the air from a confined space to the atmosphere when the confined space reaches a preselected temperature greater than that in the conduit adjacent to the atmosphere includes at least one vane pivotally mounted within the conduit and preferably two. The vane or vanes are mounted so that they are movable between a generally opened position, wherein air can pass freely through the conduit, and a generally closed position, wherein air passage through the conduit is restricted. A temperature responsive drive assembly that detects the temperature of the air within the conduit is mounted therein and opens and closes the vanes. Biasing the vanes to a normally closed condition is accomplished by placing a greater portion of each vane beyond its pivotal axis and having the smaller portion of one vane cooperate with the larger portion of the other to maintain the generally closed position.

Abstract: An energy efficient apparatus suitable for use in hot, arid climates wherein a source of water is available includes in combination; a rotating wheel member which utilizes the buoyancy of outwardly extending members and a pair of temperature sensitive devices responsive to the change in ambient temperature to cause the moment about the axis of the rotating wheel member to increase, thereby aiding in the rotation of the rotating wheel member providing continuous output energy. The increase of the mechanical moment is caused by the mechanical change in position of an outwardly extending member and provides a portion of the energy obtained thereby to a spring and escapement mechanism which further couples additional energy to support the rotation of the rotating wheel member.
