| 20080282661 | Paddle assembly for corn-head sweeper - A sweeper for a corn harvester includes self-gripping paddle assemblies mounted about a drive axle. The self-gripping paddle assemblies have a plurality of paddles formed of flat plate stock with a high moment of inertia formed by stiffeners extending from the flat plate. The stiffener plates are orthogonal to the axis of the drive axle and to the base plate. The orthogonal plates have curved surfaces formed such that when the paddles are connected together, the curved surfaces grip the drive axle. One embodiment of paddle assemblies is foldable and one embodiment of paddle is formed to permit easy stacking one inside of the other for shipment | 11-20-2008 |

| 20110215652 | SUBSTANTIALLY BUMPLESS TRANSFER GRID SYNCHRONIZATION - This disclosure includes systems and methods for managing the interaction between inverter-based DC and other power systems. In one embodiment, a 3-phase isolation transformer is fluxed to create a 3-phase rotating field from the output of a source inverter. An inductive filter turns that output into three sine waves. A secondary inverter regenerates the system, sometimes after the isolation transformer is fluxed, and by advancing or retarding the secondary inverter's phase, current (and, thus, the DC voltage and power direction) is controlled. In another embodiment, an inverter is supplied by a DC source. The inverter is controlled to match its output voltage, current, and phase to a live AC grid, then the two are connected. The inverter frequency is then driven to advance the phase of the inverter in relation to the grid. Alternatively, the inverter voltage is then driven at a level greater than that of the grid. | 09-08-2011 |
