Abstract: An electrical generating device for creating supplemental electrical power includes a turbine attic ventilator that drives a generator. The generator is electrically connected to a rechargeable battery and a main power grid. The battery powers an optical smoke detector that activates an audible and/or visual alarm whenever particulate smoke is detected. Accordingly, as the ventilator is rotated by wind, the battery is recharged and the main power grid is supplemented.

Abstract: The invention is an Attic Ventilation Turbine with Integrated Flex Blade that has a Scoop-Blade Turbine Shroud with an integrated Fan constructed within the Shroud so that ambient wind rotates the Shroud. When the Shroud rotates, the Fan is rotated along with the Shroud so that warm air within the attic is pulled out of the attic through the Turbine. The Fan is constructed with a number of flexible metal Blades that flatten as the Shroud spins faster.

Abstract: A device is described which may be fashioned to be installed over an existing unprotected intermittently acting vent pipe of a building, from which malodorous internal air from bathrooms, kitchens, areas where cigar or cigarette smoking ensues and the like, are expelled. It is made from a length of pipe of slightly larger circumference than the existing vent pipe and is stably attached at its lower end to the upper end of the vent pipe. A hinged cap of the same geometric shape as the pipe but of slightly larger dimension is attached at its upper end.

Abstract: A typical turbine roof ventilator includes a turbine hood having a closed end, a ring spaced from the closed end and a series of spaced blades extending from the ring to the closed end. A novel sleeve assembly is disclosed including a first sleeve portion having a first open end and a second open end and a second sleeve portion defining a third and a fourth open end. The third end of the second sleeve portion is partly located inside the second end of the first sleeve. The second sleeve is hinged to the first sleeve portion about a pivot axis. The outside diameter of first sleeve portion is slightly smaller than the inside diameter of the second sleeve portion. Both sleeves are at least part spherical such that the second and first sleeve portions can be relatively freely rotated relative to each other about the pivot axis so that the relative angle between planes defined by the first end of the first sleeve axis and the fourth end of the second sleeve may be adjusted.

Abstract: A roof-mounted wind turbine includes turbine vanes that are linear-shaped and do not have the conventional convex curvature. Additionally, the turbine vanes are made in common with one another or with a common turbine component, so that each vane does not require individual handling nor individual attachment to the turbine assembly as is required in the construction of conventional wind turbines that are commercially available today. This is accomplished by producing the vanes by molding or extruding techniques that are commonly used in making plastic assemblies or components.

Abstract: A turbine roof ventilator includes a rotatable shaft defining an upper end and a lower end. A turbine hood is located on the upper end of the shaft and is adapted to turn with the shaft. A cylindrical sleeve is disposed below the turbine hood. The shaft is mounted in a bearing housing which is fixed relative to the cylindrical sleeve while allowing the shaft to rotate about its longitudinal axis. A fan or vane assembly is disposed on the lower end of the shaft and adapted to turn with the shaft so that as the turbine hood turns, the fan sucks air into the housing to improve the rate of flow of air through the roof ventilator.

Abstract: A draft inducer blower motor mounting and cooling construction comprising an electric motor including a housing having openings therein and a rotor mounted on a shaft, a fan blade fixed on the shaft and interposed between the motor and the draft inducer blower, and a heat shield interposed between the motor housing and the fan blade. The heat shield is fastened to the electric motor and to the housing of the inducer blower and has portions spaced from the blower housing. The heat shield further preferably includes a portion surrounding at least a part of the motor housing such that rotation of the fan blade draws cooling air through the electrical motor and about the housing of the electric motor and thereafter radially outwardly between the heat shield and the inducer blower housing to cool the electric motor and the shaft end bearing nearest the inducer housing. In another form, the portion surrounding the motor may be eliminated.

Abstract: The turbine head of a wind-powered turbine ventilator is rotatably supported on a spindle by a thrust bearing assembly. A thrust receptacle is mounted on the upper part of the turbine head to receive the supporting end of the spindle. A centering collar coupled to the lower end of the spindle limits lateral deflection of the turbine. The thrust bearing components are constructed of complementary materials, acetal resin and polyamide resin, which provide a self-lubricating effect when rubbed together.

Abstract: An improvement is provided in a roof-mounted turbine-type ventilation fan and associated air-handling duct whereby rotation of the fan is stopped and the duct is closed during periods of cold weather. Stoppage of rotation of the fan is achieved by an elongated locking pin that penetrates aligned apertures in an annular lower rim of the fan and in a bearing collar located atop the duct and normally slidably interactive with the annular lower rim. Closure of the duct is achieved by a circular butterfly damper panel positioned within the duct.
