20120009119 | METHOD AND APPARATUS FOR GENERATING HYDROGEN - Disclosed is a method for generating hydrogen. The method may include introducing water bubbles into a bottom region of a vessel containing molten aluminum allowing the water bubbles to rise within the molten aluminum, expanding as they rise. The method may further include collecting hydrogen, generated in a reaction between the water bubbles and the molten aluminum, from the vessel. Also disclosed is an apparatus for generating hydrogen that may include a vessel having an internal chamber for containing molten aluminum, at least one water inlet positioned at a bottom region of the vessel, at least one hydrogen outlet positioned at a top region of the vessel to and a heating element. | 01-12-2012 |

20150282381 | HEAT SINK DEVICE - A heat sink device includes a thermally conducting base plate configured to be thermally coupled to a heat source. A cover is located substantially opposite the base plate. A plurality of thermally conducting partitions extends laterally from the base plate to the cover. A lateral edge of each partition is in thermal contact with the base plate. The partitions partition a space between base plate and cover into an array of elongated channels with open opposite ends. When the base plate is thermally coupled to a heat source and the open opposite ends of a channel of the array of channels are aligned substantially vertically, a chimney effect air flow is sustained within each channel. | 10-01-2015 |

20100049291 | STENT WITH IMPROVED RESISTANCE TO MIGRATION - A modular mating stent is adapted to resist migration within a receiving stent. The modular mating stent has a substantially self-expandable first section of predetermined compressibility that is adapted to permit the first section to conform to the shape of a body lumen surrounding the first section. The modular mating stent also has a balloon-expandable second section that is less compressible than the first section, which is adapted to firmly engage a surface of the receiving stent surrounding the second section. | 02-25-2010 |

20080238211 | SOLID-STATE MICROSECOND CAPACITANCE CHARGER FOR HIGH VOLTAGE AND PULSED POWER - A solid-state high-voltage pulse generator based on a three-phase chopper capacitance charger is described. In a first phase, an intermediate capacitor is resonance-charged via a diode. In a second phase, the intermediate capacitor is discharged to the load through one or more solid-state switches. In a third phase, the energy remaining in the intermediate capacitor is returned to a power-supply filter capacitor. In one embodiment, the three-phase chopper includes an intermediate capacitor that is charged by first and fourth branches of a bridge and discharged by second and third branches of a bridge. In one embodiment, each branch of the bridge includes a diode in series with an inductor. In one embodiment, a composite solid-state switch connects the intermediate capacitor to a primary winding of an output transformer such that the intermediate capacitor discharges through the primary winding. In one embodiment, a secondary winding of the output transformer is provided to an output load. In one embodiment, the output load is a reactive load. In one embodiment, the output load is a capacitive load. | 10-02-2008 |

20090178372 | System For Making Pneumatically Filled Packing Cushions - System, method and material for making pneumatically filled packing cushions in which a plastic film material having two superposed layers joined together along first and second longitudinal edges is prefabricated at a first location by forming longitudinally spaced, transversely extending rows of perforations across it and sealing it together along seal lines which extend from the first edge of the material in a direction generally parallel to the rows of perforations other and terminate a short distance from the second edge to form chambers with open mouths facing the second edge between the rows of perforations. The material is then fan-folded or formed into rolls for storage and shipment. At a second location, gas is introduced into the chambers by passing the material along a tube positioned between the ends of the seals and the second edge of the material and injecting the gas into the open mouths of the chambers through openings in a side wall of the tube. The two layers are then sealed together across the open mouths to close the chambers and retain the gas in them. | 07-16-2009 |
