    Abstract: An electrical system and method for a turbine/alternator comprising a gas driven turbine and a permanent magnet alternator rotating on a common shaft includes an inverter circuit connectable either to an output circuit or the stator winding of the alternator. A control circuit during a start-up mode switches the inverter circuit to the stator winding of the alternator and during a power out mode switches the inverter circuit to the output circuit. During the power out mode, current data is sensed and is used for current limit and/or power balancing.

    Abstract: The present invention relates to an improved paper clip which is suitable for holding documents of different thicknesses. The improved paper clip includes three elements, which are a first clipping piece, a second clipping piece and a support beam. The first clipping piece is formed with a sunken slot therethrough and is connected to a bottom side of the support beam. The second clipping piece has a bending curve part and is connected to a top side of the support beam. The bending curve part is partially protruding into the sunken slot and is roughened to become a rough surface for increasing friction to tightly clamp documents. The inner surface of the support beam is a flat plane so as to provide a guiding function when the document is received between the first and second clipping pieces. The first and second clipping pieces are both adjoined to the inner surface of the support beam, such that the outer surface of the support beam substantially forms part of the outer contour oft the paper clip.

    Abstract: An electrical system for a turbine/alternator comprising a gas driven turbine and a permanent magnet alternator rotating on a common shaft includes an inverter circuit connectable either to an AC output circuit or the stator winding of the alternator. A control circuit during a startup mode switches the inverter circuit to the stator winding of the alternator and during a power out mode switches the inverter circuit to the AC output circuit. Thus, during the startup mode, the alternator functions as a motor to raise the speed of the turbine to a safe ignition speed and in the power out mode the electrical system outputs the AC output circuit, electrical power having a frequency unrelated to the rotation speed of the alternator.
