  • Patent number: 10022795
    Abstract: The present disclosure generally relates to additive manufacturing systems and methods on a large-scale format. One aspect involves a build unit that can be moved around in three dimensions by a positioning system, building separate portions of a large object. The build unit has an energy directing device that directs, e.g., laser or e-beam irradiation onto a powder layer. In the case of laser irradiation, the build volume may have a gasflow device that provides laminar gas flow to a laminar flow zone above the layer of powder. This allows for efficient removal of the smoke, condensates, and other impurities produced by irradiating the powder (the “gas plume”) without excessively disturbing the powder layer. The build unit may also have a recoater that allows it to selectively deposit particular quantities of powder in specific locations over a work surface to build large, high quality, high precision objects.

  • Patent number: 10024163
    Abstract: Methods for material build-up on a tip of a blade of a gas turbine engine are provided. The method can include inserting a material supply and an inflatable bladder between the tip and a shroud such that the material supply is exposed to the tip and the inflatable bladder is positioned between the material supply and a shroud, inflating the inflatable bladder to force contact between the material supply and the tip, and causing relative movement between the material supply and the tip. The relative movement, in combination with the radial biased contact between the material supply and the tip, creates heat through friction. As such, the relative movement can frictionally weld new material from the material supply onto the tip of the blade. For example, the heat created can be sufficient to melt the surface of the material supply to transfer material from the material supply to the tip.

  • Patent number: 10027976
    Abstract: A coding efficiency increase is achieved by using a common signalization within the bitstream with regard to activation of merging and activation of the skip mode. One possible state of one or more syntax elements within the bitstream may signalize for a current sample set of a picture that the sample set is to be merged and has no prediction residual encoded and inserted into the bitstream. A common flag may signalize whether the coding parameters associated with a current sample set are to be set according to a merge candidate or to be retrieved from the bitstream, and whether the current sample set of the picture is to be reconstructed based on a prediction signal depending on the coding parameters associated with the current sample set, without any residual data, or to be reconstructed by refining the prediction signal depending on the coding parameters associated with the current sample set by means of residual data within the bitstream.

  • Patent number: 10027118
    Abstract: The present disclosure is directed to a system and method for balancing reactive power loading between multiple renewable energy power systems coupled to a power grid at a point of regulation (POR). The method includes determining a voltage error based on a voltage reference and a measured voltage at the POR. The method also includes measuring at least one operating condition from each of the power systems. Further, the method includes determining a per unit actual reactive power for each of the power systems based on at least one of the actual operating conditions and determining a per unit average reactive power from the power systems based on at least one of the actual operating conditions. Thus, the method also includes determining a voltage reference command for each of the power systems as a function of the voltage error, the per unit reactive power, and/or the per unit average reactive power.

  • Publication number: 20180195360
    Abstract: A fracturing system includes a fracturing spool that mounts onto a wellhead assembly for injecting fracturing fluid into a well beneath the wellhead assembly. The fracturing system includes an isolation sleeve and fracturing spool. The isolation sleeve inserts in an axial bore of the fracturing spool, and has a lower end that extends into the wellhead to isolate and protect portions of the wellhead assembly from the fracturing fluid. A groove in an inner surface of the fracturing spool receives an annular seal for sealing between the isolation sleeve and fracturing spool. Injecting a viscous fluid into the groove energizes the seal, and blocks high pressure fracturing fluid from flowing between the isolation sleeve and fracturing spool.

  • Patent number: 10018129
    Abstract: In a method of controlling a dual fuel engine in which power in the form of a first gaseous fuel and in the form of a self-igniting second fuel is fed to at least one combustion chamber, a knock signal representative of the combustion chamber is detected. When a knock signal indicating a knock of at least a first intensity is detected, the amount of first fuel fed to the combustion chamber of the engine is increased, the increased introduction of power into the combustion chamber caused by the increase in the amount of first fuel being compensated by a corresponding reduction in the power contribution of the second fuel. When a knock signal indicating a knock of at least a second intensity greater than the first intensity is detected, the amount of first fuel is reduced.
