20100141221 | DELIVERED ENERGY COMPENSATION DURING PLASMA PROCESSING - An apparatus and method for controlling an application of power to power a plasma chamber. A detector detects actual power out from the power stage to the plasma chamber during a sampling interval. A compare module compares the actual power out during the sampling interval to a present power setting during the sampling interval and generates a compensation value. An adjust module updates the present power setting for the power stage with the compensation value to provide a new power setting for the power stage to control the power out from power stage to the plasma chamber during the deposition process whereby power losses occurring during the deposition process are compensated during the deposition process. If there is a fixed time period for the deposition process, the compensation method and apparatus may be used to compensate the deposition process for energy losses without extending the duration of the deposition process. | 06-10-2010 |

20090206193 | Ballistically deployed telescoping aircraft wing - An apparatus for increasing an aerodynamic surface area of an aircraft, e.g., a wing thereof, includes coaxially disposed first and second elongated airfoils and an inflatable device arranged to move the first airfoil coaxially relative to the second airfoil. The second airfoil has a root end fixed to the vehicle and an opposite outboard end, and the first airfoil is arranged to move axially between a retracted position generally inboard of the outboard end of the second airfoil and a deployed position generally outboard thereof. When the movable airfoil is deployed, a latching mechanism locks it in position. The inflatable device can include a collapsible duct that is sealed at one end and coupled at a second end to an inflating source, such as a reservoir of a compressed gas or a pyrotechnic gas generator. | 08-20-2009 |

20090026321 | MORPHING AIRCRAFT WITH TELESCOPIC LIFTING AND CONTROL SURFACES - A morphing aircraft includes a lifting body and a telescopic lifting or control surface, such as a wing, coupled to the lifting body. The lifting surface is deployable between extended and retracted positions relative to the lifting body and configured such that, when disposed in the extended position, the flight characteristics of the aircraft correspond to those of a low-speed, high-lift aircraft, and when disposed in the retracted position, the flight characteristics of the air-craft correspond to those of a high-speed, low-lift aircraft, the lifting surface is disposed entirely within the lifting body, and an outboard end surface of the lifting surface blends continuously into an outer mold line surface of the lifting body. | 01-29-2009 |

20090252965 | Surface functionalization and coating of flame-generated nanoparticles - A method for generating a chemically bonded organic functionality on the surface of particles or for condensing an organic compound onto the particle surface giving an organic coating is described. The method comprises a step of contacting a vapour containing an organic compound and a gaseous process stream containing flame-generated particles so as to react the organic compound with surface groups on the particles to give a chemically bonded organic functionality to the particle surface or so as to result in an organic coating. | 10-08-2009 |

20100128834 | ZIRCONIUM ALLOYS WITH IMPROVED CORROSION RESISTANCE AND METHOD FOR FABRICATING ZIRCONIUM ALLOYS WITH IMPROVED CORROSION RESISTANCE - Articles, such as tubing or strips, which have excellent corrosion resistance to water or steam at elevated temperatures, are produced from alloys having 0.2 to 1.5 weight percent niobium, 0.01 to 0.45 weight percent iron, at least one additional alloy element selected from 0.02 to 0.8 weight percent tin, 0.05 to 0.5 weight percent chromium, 0.02 to 0.3 weight percent copper, 0.1 to 0.3 weight percent vanadium, 0.01 to 0.1 weight percent nickel, the balance at least 97 weight percent zirconium, including impurities, wherein the alloy may be fabricated from a process of forging the zirconium alloy into a material, beta quenching the material, forming the material by extruding or hot rolling the material, cold working the material with one or a multiplicity of cold working steps, wherein the cold working step includes cold reducing the material and annealing the material at an intermediate anneal temperature of 960°-1105° F., and final working and annealing of the material. The articles formed also show improved weld corrosion resistance with the addition of chromium. | 05-27-2010 |
20110293466 | ZIRCONIUM ALLOYS WITH IMPROVED CORROSION/CREEP RESISTANCE DUE TO FINAL HEAT TREATMENTS - Articles, such as tubing or strips, which have excellent corrosion resistance to water or steam at elevated temperatures, are produced from alloys having 0.2 to 1.5 weight percent niobium, 0.01 to 0.6 weight percent iron, and optionally additional alloy elements selected from the group consisting of tin, chromium, copper, vanadium, and nickel with the balance at least 97 weight percent zirconium, including impurities, where a necessary final heat treatment includes one of i) a SRA or PRXA (15-20% RXA) final heat treatment, or ii) a PRXA (80-95% RXA) or RXA final heat treatment. | 12-01-2011 |
