20120090319 | COMPOUNDED DILUTION AND AIR CHARGING DEVICE - An internal combustion engine includes a turbocharger and a selectively operable positive displacement supercharger downstream of the turbocharger in the intake path. An input shaft of the supercharger is mechanically coupled to and driven by a piston-driven crankshaft. A bypass valve is configured to selectively bypass at least a portion of the air from the turbocharger air outlet around the supercharger. Power and fuel consumption are optimized by operating the supercharger to dilute the fuel-air mixture to achieve an excess air factor λ above 1.0, and in some cases above the upper range (λ=1.3) of normal stoichiometric operation. The engine can operate in a lean low temperature combustion mode (e.g., HCCI) with the supercharger operating, and in a stoichiometric spark ignition combustion mode with the supercharger bypassed. | 04-19-2012 |

20140050547 | ROTOR BLADE TRANSPORTATION SYSTEM - A transportation system is disclosed for transporting a rotor blade having a first end and a second end defining a rotor blade length. The transportation system includes a truck configured to transport the rotor blade, the truck including a bed having a forward end and a distal end defining a bed length. The transportation system further includes a first fixture configured on the bed, the first fixture comprising a generally arcuate guide member and a support frame slidable along the guide member, the support frame configured to support the rotor blade. The transportation system further includes a second fixture configured on the bed for one of slidable support or rotatable support of the rotor blade. Movement of at least one of the first fixture or the second fixture rotates the rotor blade within a plane defined by the bed. | 02-20-2014 |

20150037166 | WIND TURBINE TOWER HAVING FLOATING PLATFORM - Towers for wind turbines are provided. In one embodiment, a tower includes a hollow shell defining an interior, the hollow shell extending generally along a longitudinal axis. The tower further includes a platform disposed in the interior and connected to the shell. The platform includes a first plate fixedly connected to the shell. The platform further includes a second plate movably connected to the first plate such that relative movement of the first plate and second plate is permitted in a plane generally transverse to the longitudinal axis. | 02-05-2015 |
