Abstract: Vents are disclosed for covering openings on roofs. The disclosed vents cover openings on metal roofs and prevent moisture and objects from entering the opening while allowing air to pass therethrough. The vents disclosed herein also prevent moisture from entering the building through openings that can be created when the vents are attached to a roof. The vents include a cap, a collar, and a flashing configured to contact the roof. The vents can also include a screen placed between the cap and the collar. The collar can have arms formed on an upper portion thereof to facilitate connection of the collar to the cap. Feet can be formed on a bottom portion of the collar. Once the vent is fully assembled, the feet can be positioned underneath the flashing and can be the main connection point of the vent to a roof. Due to the design of this assembly, fasteners pass through the feet providing a sound and secure attachment to the roof.

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: A protective vent for a water storage tank having an inner flexible fine mesh screen and an outer heavier more rigid screen with a wider mesh. Both screens are mounted on a frame structure under an extending upper protective cover. Air from the water tank can communicate with ambient air after passing through the two screens. The outer screen acts to protect the tank and the inner screen from birds, grasshoppers and large insects while the flexible wrinkled inner screen protects against frost and smaller insects entering the tank. Fiberglass may be used for the fine inner screen and galvanized hardware cloth for the outer screen. The vent is constructed to be mounted over an existing vent stack from the storage tank. On those water storage tanks whose venting capacity is no longer adequate and an increase in air flow is desired, a new larger diameter vent stack can be installed in place of the existing smaller stack with this protective vent system.

Abstract: A ventilating device for a home or other building includes a frame for covering a ventilating opening in the structure. The frame defines a passage for communicating the ventilating opening to the atmosphere. The passage contains a freely movable valve member which normally rests in an inactive position under gravitational force to permit venting through the passage. The valve member moves in response to wind pressure to an active position in which the member seats against a seating surface within the passage to prevent entry of wind-driven precipitation into the structure. When the wind subsides, the valve member returns under the force of gravity to its inactive position.

Abstract: A roof vent (8) comprises a conduit having an open entry end adapted for being arranged in sealing communication with an aperture in a roof surface, and an exit end spaced from said entry end, shield means (31) adapted for preventing entry of rain into said conduit, a valve assembly for controlling flow of air or gas, said valve assembly comprising a valve member (13, 22) adapted for opening to passage of air or gas when the pressure at the entry end exceeds the pressure at the exit end and adapted for closing on other conditions to prevent back-flow of air or gas, and thermostat means (27) adapted for opening said valve member to bidirectional passage of air or gas when the temperature at said thermostat means exceeds a predetermined level.

Abstract: This static ventilator is made with three parts: 1) a hollow housing, triangular shaped with circumferential sidewalls and louvers attached to the outside walls, 2) a triangular shaped base fixed to the roof and 3) a cap at the top. The hollow housing is the part that actually does the ventilation. Each of its louvers is inclined downwards and out and comes with a piece of filter material preventing anything from entering the vent openings and allowing the air to circulate. The triangular shape of the hollow housing allows the wind to slide laterally along each side of the ventilator and prevents any snow or debris accumulation at the base and on the louvers of the ventilator. In order to secure the hollow housing to the roof surface, a triangular shaped piece serves as a base where the hollow housing is inserted. This base also lets the condensed water flow out of the hollow housing. The cap seals the hollow housing and prevents anything from falling straight into the ventilator.
