20130064663 | MORPHING SEGMENTED WIND TURBINE AND RELATED METHOD - A downwind morphing rotor that exhibits bending loads that will be reduced by aligning the rotor blades with the composite forces. This reduces the net loads on the blades which therefore allow for a reduced blade mass for a given maximum stress. Also provided is a pre-aligned configuration rotor whereby the rotor geometry and orientation does not change with wind speed, and instead is fixed at a constant downwind deflection consistent with alignment at or near the rated wind speed conditions. Also provided is a twist morphing rotor where the airfoil-shapes around the spars twist relative to the wind due to aerodynamic forces so as to unload the rotors when there is a gust. This can help reduce unsteady stresses on the blade and therefore may allow for reduced blade mass and cost. The twist morphing rotor may be combined with either downwind morphing rotor or pre-alignment rotor. | 03-14-2013 |

20080245903 | Method and apparatus for online flow control over the span of a high aspect ratio slot jet - A method and apparatus for controlling local flow along a slot jet with applications to airknives is disclosed. The airknife provides improved options for on-line control over coating thickness and edge build-up prevention. The gap of the slot nozzle of the airknife can remain constant while the outflow pattern is controlled by a series of preset throttle valves in combination with a single moving component, the multi-port aero-valve. This valve can be actuated locally or remotely, in rotation or translation, thereby changing gradually from a conventional uniform outflow to one which increases in velocity and mass flow rate along the airknife span to produce a bow effect. The valve can also change gradually from a conventional uniform outflow to one which increases in velocity, mass flow rate and outflow angle along the span to simulate bow effect in combination with fan-like outflow. | 10-09-2008 |

20110220041 | Accelerated compression ignition engine for HCCI - An internal combustion engine has cylinder wall cavities located near the top dead center stroke end to allow optimizing the compression ratio in first stage compression, as function of fuel octane number used. The volume of the cylinder wall cavities is designed to be adjustable, even when the engine is operating. Using a conventional piston motion, the second stage compression becomes accelerated as soon the upper piston ring seals-off the cylinder wall cavities. This is due to the sudden significant reduction in volume. During the power stroke, after the upper piston ring opens the cylinder wall cavities; their fuel content is ignited by second stage combustion products. Because the torque required during accelerated compression is no greater than during first stage compression, stresses in the crankshaft are no more than in conventional spark ignition engines. This allows small displacement engines to be of light weight and to be hand cranked. | 09-15-2011 |
