Abstract: A wind turbine is provided that minimizes the size of the drive train and nacelle while maintaining the power electronics and transformer at the top of the tower. The turbine includes a direct drive generator having an integrated disk brake positioned radially inside the stator while minimizing the potential for contamination. The turbine further includes a means for mounting a transformer below the nacelle within the tower.

Abstract: A system and method are provided for monitoring the levels of combustible gas in a gas stream. The system includes means for controlling the relative humidity of the the gas stream to maintain a humidity level in the performance range of combustible gas sensors. A number techniques are illustrated for achieving the humidity control, including, secondary phase separations, mixing the gas with dry air and adjusting of the gas stream temperature.

Abstract: A system and method are provided for generating electricity for use with liquid hydrogen storage facility. The system includes a liquid hydrogen storage tank with a pressure relief. An energy conversion device is connected to the pressure relief valve an converts the hydrogen into rotational energy to operate an electrical generator. Electricity created by the generator can be fed back to operate ancillary loads in the facility, or sold for use in a main electrical grid.

Abstract: A system and method are provided for generating hydrogen for use with an internal combustion engine. The system includes a venturi device coupled with an exhaust stream from the internal combustion engine. The venturi device creates a gas flow through a condenser to generate reactant water. After the reactant water is polished to remove contaminants, hydrogen and oxygen are disassociated using a PEM based electrolyzer. The hydrogen gas is used by the internal combustion engine to assist in the combustion process and reduce pollutant emissions.

Abstract: A circuit breaker assembly including a first and second circuit breakers each having toggle switch assemblies movable between ON and OFF positions. The toggle switch assemblies have connectors coupled thereto for preventing both circuit breakers from being in the ON position at the same time.

Abstract: A rotary contact circuit breaker employs a crank to couple a switching mechanism to the rotary contact pole structure. The use of a crank allows for the mechanism and pole structure the individually optimized without effecting the performance of the other. In particular the crank allows for a mechanism that is able to achieve maximum torque delivery to the pole structure.

Abstract: A hollow carrier having a handle in the shape of a jack-o-lantern or the like is provided with a light and diffuser assembly. When the light is activated, a portion of the light is reflected onto a path external to the carrier while another portion is reflected back into the carrier illuminating the carriers interior allowing the person holding the carrier to be visible from all directions.

Abstract: A circuit interrupter of the type including an electronic trip unit for overcurrent determination which includes a small-sized iron core current transformer to power the trip unit electronics along with a giant magnetic resistor semiconductor (GMR) to sense the current flow within the protected circuit.

Abstract: The circuit breaker is characterized by separable contacts operable between a closed and an open position a contact arm having a latching surface and a latch arranged to engage the latching surface when the contacts are blown-open under short-circuit conditions. The arrangement of the latch allows for a positive lock under high magnitude short circuit levels while minimizing the force required by a mechanism to unlock the arm.

Abstract: A ground fault protection module is attached to a circuit breaker employing a thermal-magnetic trip unit to separate the circuit breaker contacts upon occurrence of a ground fault. The ground fault module contains a logic circuit and a giant magnetic resistor for detecting the ground fault.
