20100014973 | Vertical Axis Fluid Flow Turbine System - The present invention is vertical axis fluid flow turbine system for generating an alternative fuel. The turbines of the present invention are centered between at least two support structures so that the rotor holding the hub and the blades is perpendicular to the ground, rooftop, or the floor of a body of water and the axis of the blades coming from the hub are parallel to the ground, rooftop, floating structure, or the floor of a body of water. The turbines are secured to the support structures using struts. The struts are attached to each support structure and to the nacelle of each turbine. Attaching each turbine in this manner allows the turbines of the present invention to be stacked one on top of the other, that in turns minimizes the footprint of the vertical axis fluid flow turbine system. | 01-21-2010 |
20110305570 | AERODYNAMIC DEAD ZONE-LESS TRIPLE ROTORS INTEGRATED WIND POWER DRIVEN SYSTEM - The present invention relates to an aerodynamic dead zone-less triple-rotor integrated wind power driven system wherein control rotor | 12-15-2011 |
20150292514 | DEVICE AND METHOD OF CONTROLLING COOLING TOWERS, AND HEAT SOURCE SYSTEM - To achieve energy saving in the cooling towers as a whole in a heat source system including a plurality of cooling towers connected in parallel to a common chiller. In a heat source system, a plurality of cooling towers are connected in parallel to a common chiller. The cooling towers cool cooling water used and thereby heated in the chiller, and supplies the cooled cooling water to the chiller. A cooling tower control device for controlling the cooling towers starts all the cooling towers at the start of the heat source system. | 10-15-2015 |
20150367935 | PASSIVE DEPLOYMENT MECHANISM FOR LIFT FAN - A vertical takeoff and landing aircraft includes rotors that provide vertical and horizontal thrust. During forward motion, the vertical lift system is inactive. A lift fan mechanism positions the fan blades of the aircraft in a collapsed configuration when the vertical lift system is inactive and positions the fan blades of the aircraft in a deployed configuration when the vertical lift system is active. | 12-24-2015 |

20110142630 | WIND TURBINE PITCH-ANGLE CONTROL DEVICE AND METHOD THEREOF - The object is to reduce aerodynamic load when a wind turbine is halted. When a wind turbine halt command is input, pitch angles of wind turbine blades | 06-16-2011 |
20120099987 | STATIONARY ACTUATOR DEVICE FOR CONTROLLING THE PITCH OF FAN BLADES OF A TURBOPROP - A device for controlling pitch of fan blades of a turboprop including at least one set of variable-pitch fan blades constrained to rotate with a rotary ring centered on a longitudinal axis and mechanically connected to a turbine rotor, each blade coupled for pitch adjustment to a synchronization ring. A turntable is mounted via a rotary connection to a rod of an actuator that is secured to a stationary structural element of the turboprop, the turntable being mechanically connected to the synchronization ring by a plurality of connection arms hinge-mounted on the turntable and connected to the synchronization ring such that a longitudinal movement of the turntable under drive from the actuator causes the synchronization ring to turn about the longitudinal axis. | 04-26-2012 |
