Abstract: A venting system includes a venting installation cap assembly for a venting system having at least an outer wall and an inner exhaust tube. The assembly includes an exhaust cap having an exhaust path coupled to the inner exhaust tube defined by a pipe section. A planar support ring having an annulus through which the pipe section passes rests on the outer tube or an adapter to the outer tube. The ring annulus surrounds the pipe section and has a diameter greater than a diameter of the outer wall. The planar support ring includes a plurality of airflow regions, surrounds the exhaust path and providing an airflow path between an exterior and a region between the outer wall and the inner exhaust tube.

Abstract: An exhaust diluting and diffusing apparatus includes a first pipe forming a vertically directed outlet for an exhaust conduit and a second diffuser pipe mounted to receive an exhaust gas flow from the outlet of the first pipe, the second pipe having a diameter greater than the diameter of the first pipe to define an ambient air inlet gap surrounding the outlet of the first pipe, and being sufficiently wide to allow the exhaust gas to expand and diffuse in the second pipe. The device further includes a dispersing outlet mounted at an end of the second pipe and configured to direct exhaust gas radially outward, an area defined by the diffuser outlet being greater than an area of the outlet of the first pipe.

Abstract: The present invention provides an omnidirectional wind collection apparatus. The wind collector includes an outer housing with a peripheral wind inlet circumferentially formed therein. An inner housing disposed within the outer housing has an inner surface with a first opening at a lower end thereof to guide the collected wind to a smaller second opening at the top end. The inner surface is curved between the bottom and top openings to form a progressively narrower passage. The configuration of the inner surface creates a Venturi effect such that the wind is accelerated toward the second opening. A wind pass-through portion is formed above the second opening in the inner housing. Based on the Bernoulli effect, the passage of uncollected wind through this portion creates a low pressure region that expedites flow of collected wind through the first and second openings of the inner housing.

Abstract: An omnidirectional vent cap for venting holding tanks is provided. By providing a 360 degree venturi channel, the present invention can use a small movement of air to reduce the air pressure above the exhaust port to draw out vapors or gasses. Since the device is symmetrical about the central axis the movement of air can be from any direction relative to the device.

Abstract: A cap capable of being secured to a chimney or flue of either air cooled or non-air cooled type and including a base, an annular collar member for insertion into a chimney or flue, an annular shaped mesh member that is supported from the base; a top supported on the annular shaped mesh member, means supported from an outer surface of the collar member below the base and forming a ledge for support of the collar member from the chimney or flue, and an over lap joint including a lower segment that extends substantially longitudinal of the collar member and a top segment that extends diagonal to the lower segment enabling compression of the diameter of the collar member.

Abstract: A chimney termination cap is provided with a body having a perimeter sidewall with a lower region adapted to be mounted to a chimney. The body has an opening for venting the chimney. A lid is mounted to a top of the body. A tray is mounted within the body for collecting precipitation. One of the body and the tray includes a drainage aperture for draining the precipitation from the tray. In one embodiment, the chimney termination cap includes an integrated slip-sleeve configured to receive a chimney flue or vent pipe.

Abstract: A waterproofing and humidity control system is provided for a building which includes drain members located in trenches provided in ground beneath and adjacent the basement of the building. A suction and fan and motor assembly is located within a housing positioned within the building. Conduits communicate with the drain members and the motor and fan housing. An exhaust vent is located in the wall of the building spaced from the motor housing and has an air inlet and outlet. A separate conduit or duct communicates with and connects the inlet of the vent with an outlet of the motor and fan housing. The duct may extend between joints in the wall of the building. An adapter conduit is used with the system and is positioned between the motor and fan housing and the duct. The adapter conduit has portions which are offset from each other to allow the fan housing to be positioned in front of a finished basement wall.

Abstract: A new accessory for combustion devices such as swimming pool heaters for preventing downdrafting and allowing for proper ventilation. The inventive device includes a vertically disposed pipe extending upwardly from a combustion device. The pipe has a generally cylindrical configuration. The pipe has an open upper end. The open upper end has a plurality of circumferentially spaced brackets extending upwardly therefrom. Upper ends of the brackets have an upper pipe extending upwardly therefrom. The upper pipe has open upper and lower ends. The open upper end of the upper pipe has a plurality of circumferentially spaced brackets extending outwardly therefrom. A draft hood is secured to the brackets of the vertically disposed pipe downwardly of the upper ends thereof. A vent cap is removably secured to upper ends of the brackets of the upper pipe.

Abstract: A smoke extraction apparatus consists essentially in a structural shape of a type of a molding plane given to the exterior wall of the footing (2), which forms the common base element of the static module and of the dynamic module. The dynamic module can be indiscriminately associated to the footing (2) according to the climatic conditions of the location or according to the desired level of underpressure, wherein the dynamic module is formed by a ferrule (15) made of a lower cylindrical part (16), which lower cylindrical part (16) extends in the upward direction in a truncate-cone part (17), where the truncated-cone part (7) ends in a turned-down exterior edge (18). The ferrule (15) is also formed surrounding the turbine (13) and is surmounted by the truncated-cone muffle (19), where the small base of the truncated-cone muffle (19) is extended upwardly in a neck (21), which neck (21) surrounds the electric motor (14), where the electric motor (14) keeps the turbine (13) in motion.
