Publication number: 20040084975Abstract: In a generator with indirect cooling, the stator has a core 12 comprising mutually spaced packets of core laminations, radial ducts 11 being defined between the packets for the passage of gaseous coolant between the inner and outer peripheries of the core. The core 12 has axial slots 18 which accommodate armature bars 16, 17. The stator incorporates baffles 19 arranged in such a manner that gaseous coolant flowing radially in a radial duct 11a from one periphery of the core enters a slot 18 adjacent the duct 11a and flows in a direction along the slot 18 before entering one of the radial ducts, in which it flows radially toward the other periphery of the core. Accordingly, heat from the bars 16, 17 primarily passes directly into the flowing gaseous coolant. The radial flow may be either inwards (as shown) or outwards.Type: ApplicationFiled: September 23, 2003Publication date: May 6, 2004Inventor: Denis Thiot

Publication number: 20040084977Abstract: A cooling system for a sealed permanent magnet generator is disclosed that has a rotor shaft that is hollow. Permanent magnets mount on the exterior of the hollow rotor shaft. The rotor shaft has a pressed aluminum tube in various configuration on the inside bore with an end-mounted fan. The aluminum tube acts as a heat sink to draw the heat generated by the magnets through the rotor shaft and aluminum tube. The fan draws cooling air through the hollow bore of the rotor shaft thus cooling the magnets and forces the heated air through passages on the exterior of the stator housing. Because the airflow is not in contact with the electrical portions of the generator the cooling system will perform in dusty, wet and explosive environments. In another configuration a refrigeration compressor installed in the rotor shaft bore cools the rotor shaft and the fan cools the stator passages.Type: ApplicationFiled: July 28, 2003Publication date: May 6, 2004Inventor: John C.

Publication number: 20040085016Abstract: A highly transparent non-metallic cathode is disclosed that comprises a metal-doped organic electron injection layer that is in direct contact with a transparent non-metallic electron injecting cathode layer, such as indium tin oxide (ITO), wherein the metal-doped organic electron injection layer also functions as an exciton blocking or hole blocking layer. The metal-doped organic electron injection layer is created by diffusing an ultra-thin layer of about 5-10 Å of a highly electropositive metal such as Li throughout the layer. A representative embodiment of the highly transparent non-metallic cathode comprises a layer of ITO, a layer of 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline (BCP), which acts as an electron injection, exciton blocking, and hole blocking layer, and an ultra-thin layer of lithium, which degenerately dopes the layer of BCP, improving the electron injecting properties of the BCP layer.Type: ApplicationFiled: October 28, 2003Publication date: May 6, 2004Inventors: Guatam Parthasarathy, Chihaya Adachi, Paul E.
