  • Patent number: 8215897
    Abstract: A vertical wind turbine includes a blade which has opposite force producing sides that lie on opposite sides of the longitudinal axis along its direction of travel. The aerodynamic surfaces are driven by the wind through four phases of rotation. Driving torque is produced during three of the four phases. The blade includes a v-shaped nosepiece with rearward facing surfaces on each side that cup the wind during three of the four phases. The split tail of the blade captures the wind during a down wind phase of rotation.
    Type: Grant

  • Patent number: 7487922
    Abstract: A small windmill is provided upstream of a damper in an air duct. When air flows in the duct it rotates the windmill. The windmill shaft is connected by a cable to the damper operator through a transmission means, such that, as the shaft turns, it takes-up the cable an opens the damper.

  • Patent number: 6557583
    Abstract: A damper assembly in which the position of the damper blades is controlled by an electric powered actuator. The powered actuator rotates a threaded lead screw shaft attached to an operator means attached to the damper blades of the damper, which causes the damper blades to open and close or be positioned somewhere in-between. The actuator can be controlled by sensors in a remote location. The actuator allows the damper to be modulated to set up pressure differentials and to be closed well in advance of oncoming smoke, fire, or other detected toxic fumes. There are a variety of nuts and gear arrangements coacting with the lead screw to drive the operator.

  • Publication number: 20020175307
    Abstract: A butterfly damper has a plurality of blades movable between an open and a closed position in response to an operating means attached to the blades and attached to an actuating means. A shaft rotatable about its axis in response to said actuating means has crank arm means attached to it and to said blades, to open and close said damper in response to rotation of said shaft. Connector arm means are pivotally connected to crank arms and pivotally connected to said blades at pivot point locations such that the pivot points of said pivotal connections are over center of the plane of the axis of said shaft when the blades are in the closed position.

  • Patent number: 6447393
    Abstract: A damper assembly in which the position of the damper blades is controlled by a powered actuator which can be powered by a pneumatic drive, an electric motor drive, or other suitable power source. The powered actuator moves a drive shaft attached to the damper blades which causes the damper blades to open and close or be positioned somewhere in-between. The actuator can be controlled by sensors in a remote location. The actuator allows the damper to be modulated to set up pressure differentials and to be closed well in advance of oncoming smoke, fire, or other detected toxic fumes.

  • Patent number: 6224481
    Abstract: A powered damper assembly in which closure of the damper blades is controlled by a powered actuator which can be powered by a pneumatic drive, an electric motor drive, or other suitable power source. The powered actuator moves a drive shaft attached to the damper blades which causes the damper blades to cycle between an open position and a closed position. The actuator can be controlled by sensors in a remote location, which allows the damper to be modulate it to set up pressure differentials and to be closed well in advance of oncoming smoke, fire, or other detected toxic fumes. The powered actuator maintains pressure on the damper blades to seal the damper tightly and prevent both smoke and fire from easily penetrating the damper. Optional remote placement of the sensors allow the damper be closed well in advance of the arrival of smoke, fumes, fire, etc. The remote sensors communicate with the dampers via direct wiring or, alternatively, via wireless transmission.
