Abstract: A system including: a first turbine segment comprising a first blade coupled to a first shank. The system also includes a second turbine segment including a second blade coupled to a second shank, as well as an elongated flexible seal disposed in a gap between the first and second shanks. The elongated flexible seal includes an opening configured to channel a fluid flow into a hollow region of the elongated flexible seal to induce expansion of the elongated flexible seal in the gap.

Patent number: 8826679
Abstract: Apparatus and methodologies are provided to improve the refrigeration system by precisely controlling refrigerator compartment and heat exchanger temperatures through continuous modulation of device speeds or positions to match capacity with instantaneous load. A controller in a refrigerator is configured to provide a plurality of control loops to control various operational aspects of selected components in the refrigerator. A first loop controls the operating speed of a compressor based on temperature of the evaporator or based on the desired speed of an evaporator fan. A second control loop controls speed of an evaporator fan to maintain a prescribed freezer compartment temperature. A third control loop maintains a prescribed temperature in a fresh food compartment. In certain embodiments selected of the control loops may be thermodynamically coupled by way of thermal interaction between the various cooled compartments rather than being electrically coupled.

Patent number: 8826520
Abstract: This disclosure describes embodiments of an apparatus for use to extract a rotor from a generator. The apparatus can include a central mount element that secures to the end of the rotor. A pair of support members coupled to the sides of the central mount element. The support members can include a load bearing element that permits travel of the apparatus on a surface, e.g., a platform proximate to the turbine generator. During implementation, the apparatus is configured to direct pulling forces along the center axis of the rotor to restrict movement of the rotor and, in particular, limit rotation of the rotor that can result in inadvertent contact with the stator or other parts of the generator.

Patent number: 8826667
Abstract: A system includes a gas turbine combustor, which includes a combustion liner disposed about a combustion region, a flow sleeve disposed about the combustion liner, an air passage between the combustion liner and the flow sleeve, and a structure extending between the combustion liner and the flow sleeve. The structure obstructs an airflow path through the air passage. The gas turbine combustor also includes an aerodynamic wake reducer configured to redirect an airflow around the structure to reduce a wake region downstream of the structure.

Patent number: 8827641
Abstract: A turbine nozzle is provided including a nozzle airfoil having an airfoil shape, the nozzle airfoil having a nominal profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in Table 1 wherein the Cartesian coordinate values of X, Y and Z are non-dimensional values from 0% to 100% convertible to dimensional distances in inches by multiplying the Cartesian coordinate values of X, Y and Z by a height of the airfoil in inches, and wherein X and Y are distances in inches which, when connected by smooth continuing arcs, define airfoil profile sections at each distance Z, the airfoil profile sections at Z distances being joined smoothly with one another to form a complete airfoil shape.
