  • Publication number: 20160136725
    Abstract: A method for making an equiaxed investment casting. The method utilizes an ultrasonic generator to send an ultrasonic pulse into molten metal in an investment casting mold. The investment casting mold is positioned within a working zone of furnace having low output induction coils for generating a convection current in molten metal. The ultrasonic pulse separates dendrites growing from the face of the mold inward into the molten metal. Instead, equiaxed grains can nucleate within the molten metal. In addition, the ultrasonic pulse and the low output induction coils circulate the molten metal as solute is rejected from solidifying equiaxed grains. The mixing reduces the effects of segregation in the solidifying alloy and assists in nucleating equiaxed grains.

  • Patent number: 9341113
    Abstract: An attemperation system and an atomizing air system are integrated for a combined cycle turbine including a gas turbine and a steam turbine. The atomizing air system receives compressor discharge air for fuel atomization. The atomizing air system includes an atomizing air cooler that serves to cool the compressor discharge air. A heat recovery steam generator receives exhaust from the gas turbine and generates steam for input to the steam turbine via an attemperation system. A feed water circuit draws feed water from the heat recovery steam generator and communicates in a heat exchange relationship with the atomizing air cooler to heat the feed water. The feed water circuit communicates the heated feed water to the attemperation system of the heat recovery steam generator.

  • Patent number: 9343991
    Abstract: Systems and methods for reducing current imbalance between parallel bridge circuits used in a power converter of a power generation system, such as a wind driven doubly fed induction generator (DFIG) system, are provided. The power converter can include a plurality of bridge circuits coupled in parallel to increase the output power capability of the system. Each of the bridge circuits can include a pair of switching elements, such as insulated gate bipolar transistors (IGBTs), coupled in series with one another. The switching elements of the parallel bridge circuits can be controlled, for instance, using control commands (e.g. pulse width modulation commands) according to a substantially non-interleaved switching pattern. The timing of the control commands according to the substantially non-interleaved switching pattern can be adjusted to reduce current imbalance between the parallel bridge circuits.

  • Publication number: 20160131793
    Abstract: A method and system for analyzing a core sample from a wellbore, where the analysis takes place in the field and proximate the wellbore. The system includes trailers adjacent one another and on a drilling pad, so that real time analysis of the core sample can occur after being extracted from the wellbore. One of the trailers can include a unit for scanning the core sample and obtaining information within the sample. Other trailers can include units that further analyze the core, such as by grinding, laser spectroscopy, Raman spectroscopy, and scanning the core material nano-structure. The core sample scanning involves a computerized tomography (CT) scan, where a length of core is analyzed in the scanning unit.

  • Publication number: 20160131796
    Abstract: A method of analyzing a core sample from a wellbore by creating a visual composite image of the core sample that is based on a scan of the core sample. The scan directs radiation at the core sample, such as a computerized tomography (CT) scan, and obtains scan data by estimating radiation absorbed by material in the core sample. The composite image is made up of an arrangement of voxels, where each voxel represents a designated volume of the core sample, and is are assigned a value that corresponds to a measured value of radiation absorbed in the designated volume of the core sample.
