Abstract: The invention provides a device for removing heat from a building, the device having: a first tubular member defining a first cavity; a second tubular member defining a second cavity, whereby said second tubular member resides within the first cavity and is coaxial to the first tubular member; and a double conic body coaxially residing in the first cavity and coaxially positioned with the second tubular member. Also provided is a method for removing heat from a building, the method having the steps of: directing heat-containing exhaust emanating from a flue, defining a first diameter, to a passageway received by the flue, whereby the passageway defines a longitudinal axis and a periphery circumscribing the axis; forming the directed exhaust into a slipstream, wherein the slipstream generally travels along the longitudinal axis; and routing precipitation entering the passageway to the periphery.

Abstract: A buttressed hinge assembly or a flexible hinge assembly adjusts to fit a vent on a wall or a roof in order to hold a fan thereon, which fan is especially suitable for a restaurant roof or wall. The hinge assembly attaches to a roof or wall vent to hold the fan in a proper position, yet permits the fan to be easily moved for cleaning of vent and the fan.

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: The automatic vent damper has various embodiments of a wind actuated vent system, which automatically closes to preclude entry of wind blown water when a wind of predetermined velocity and direction acts upon the device. The damper may be installed as an off-ridge or ridge vent system, or in other operating environments and installations as desired. Various mechanisms are used to operate the device, with all including one or more springs, which hold a rigid door or flap, open in light wind conditions. However, when a wind of sufficient velocity blows toward the vent opening, the door or flap is closed due to aerodynamic forces thereon to preclude entry of wind blown water into the device. The door or flap automatically opens again due to the spring mechanism when the wind abates.

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: A vented building includes a structure with a roof, the roof including a sloping support surface having an opening therein and roofing materials on the support surface. A housing with peripheral walls surrounded by and connected to a flashing is mounted on and in alignment with the opening in the support surface such that the flashing is supported by the support surface and covered by roofing material. At least one opening in the housing is spaced above the flashing, and a gasket is located within the housing and sealing the inside of the housing. A pipe extends from within the structure to the gasket with the gasket sealingly receiving the pipe. Thus, the pipe is provided with a vent through the opening in the housing to vent the pipe to the exterior of the building through the building's roof while preventing the ingress of precipitation to the interior of the building.
