20100132884METHOD FOR ASSEMBLING JOINTED WIND TURBINE BLADE - A method of assembling a wind turbine blade comprises providing a first blade segment comprising at least two first spar cap segments; providing a second blade segment comprising at least two second spar cap segments; inserting the second blade segment into the first blade segment wherein a spar cap cavity is formed between each set of corresponding first and second spar cap segments; injecting an adhesive into the spar cap cavities to bond the blade segments together, wherein a scarf joint is formed between each set of corresponding first and second spar cap segments.06-03-2010
20100159304THERMOMECHANICAL SEALING OF INTERCONNECT MANIFOLDS IN FUEL CELL STACKS - A planar fuel cell stack is provided. The planar fuel cell stack comprises an anode interconnect structure comprising a corrugated first internal manifold connected to a first anode flowfield; a cathode interconnect structure comprising a corrugated second internal manifold connected to a first cathode flowfield; and a thermally active, surface insulated metallic seal disposed between the corrugated parts of the anode and cathode interconnects, such that the thermally active metallic seal responds upon the application of heat to provide sealing between the anode interconnect structure and the cathode interconnect structure.06-24-2010
20110123344FLUID TURBINE BLADE AND METHOD OF PROVIDING THE SAME - A fluid turbine blade is provided. The fluid turbine blade includes a centrally disposed longitudinal spar having a substantially circumferential cross section. The fluid turbine blade also includes at least one rib assembly affixed to said longitudinal spar. The fluid turbine blade further includes a skin attached to the at least one rib.05-26-2011
20110206980ENERGY STORAGE DEVICE AND SYSTEM - An energy storage device includes a housing having an interior surface defining a volume and a plurality of solid electrolyte elements disposed in the volume. Each solid electrolyte element has a first surface that defines at least a portion of a first, cathodic chamber, and a second surface that defines a second, anodic chamber. A plurality of individual anodic chambers are thus provided, at least one of which is evacuated below atmospheric pressure. A majority of anodic chambers can be spaced from one another in a manner that provides a substantially uniform reaction rate throughout the cathodic chamber. The housing and the plurality of solid electrolyte elements together may be configured to define a second volume devoid of solid electrolyte elements and that is sufficient in size to accommodate a desired number of solid electrolyte elements and to provide an accessible cathodic chamber filling point and that is further sufficient in size to alter the volume of the cathodic chamber with respect to the volume of the plurality of anodic chambers to achieve a desired volumetric ratio between the cathodic and anodic chambers.08-25-2011
20110206984PRESEALED ANODE TUBE - A pre-sealed anode tube assembly for a sodium-metal-halide energy storage device includes an anode tube and a feed-through current collector assembly at least partially sealed within the anode tube. The pre-sealed anode tube assembly can be independently transported prior to being integrated with a desired sodium-metal-halide energy storage device.08-25-2011
20110236749SODIUM-METAL-HALIDE ENERGY STORAGE DEVICE WITH SODIUM LEVEL CONTROL MECHANISM - An energy storage device includes a housing having an interior surface defining a volume and a plurality of solid electrolyte elements disposed in the volume. Each solid electrolyte element has a first surface that defines at least a portion of a first, cathodic chamber, and a second surface that defines a second, anodic chamber. A plurality of individual anode chambers are thus provided, a majority of which are in ionic communication with the cathode chamber through a majority of the solid electrolyte elements and which are also provided with a sodium level control mechanism.09-29-2011
20120033207COMPOSITE FIBER WAVE INSPECTION SYSTEM AND METHOD - A system for inspecting a wind turbine blade having a pair of shells surrounding a shear web. The system includes a scanning machine for taking images of an interior portion of the shells of the wind turbine blade, a measuring apparatus for taking numerous measurements of a defect imaged within the shells of the wind turbine blade, and a look-up table for ascertaining the theoretical strength of the wind turbine blade.02-09-2012
