  • Patent number: 9500226
    Abstract: Various methods and systems are provided for providing coatings and textures to surfaces of a bearing assembly in an x-ray system to control the wettability of the surfaces when components of the bearing assembly rotate during operation of the x-ray system. A lubricant is disposed in a gap formed between a shaft and a sleeve of the bearing assembly such that textured and coated surfaces of the shaft and sleeve alter wetting properties between the lubricant and surfaces. The coatings and textures can be wetting or anti-wetting to further enhance control over the behavior of the lubricant.

  • Patent number: 9496894
    Abstract: A method for data compression includes reading first data representing sensor data capture, compressing the data with a lossless algorithm, transmitting the compressed data as a reference frame, reading subsequent data, calculating a delta between the first data and the subsequent data, compressing the data delta, and determining if the compression ratio of the compressed data delta is within a predetermined tolerance threshold. If the compression ratio is within the threshold, transmitting the compressed data delta frame, and repeating the calculating, compressing, and determining steps for subsequent data; Else if the compression ratio is not within the threshold, compressing the current subsequent data and transmitting the result as an updated reference frame. Then repeating the calculating, compressing, and determining steps for subsequent data. A system and a non-transitory computer-readable medium for implementing the method are also disclosed.

  • Patent number: 9494039
    Abstract: The invention refers to a stationary gas turbine arrangement with at least one turbine stage that includes at least a first row of vanes being mounted at a stationary component arranged radially outside of the first row of vanes and extending radially into an annular entrance opening of the turbine stage facing a downstream end of a combustor. Further a method for performing maintenance work on a stationary gas turbine is described. The invention is characterized in that the stationary component provides for each vane a radially orientated through-hole designed and arranged for a radial insertion and removal of the vane, and each of said vanes comprises an airfoil having at its one end directed radially outwards a contour being adapted to close the through-hole airtight by a detachable fixation means.

  • Patent number: 9494086
    Abstract: Systems and methods for improved control of a turbomachine system with a bottoming cycle system are presented. The systems and methods include a controller that utilizes modeling techniques to derive a plurality of load path curves. The controller utilizes a current load path, a minimum load path, and a constant efficiency load path. The systems and methods include a control process configured to receive a user input representative of a life cycle control modality and to execute a control action based on deriving a load efficiency by applying the current load path, the minimum load path, the constant efficiency load path, or a combination thereof, and the life cycle control modality. The control action is applied to control the turbomachine system and the bottoming cycle system fluidly coupled to the turbomachine system. Further, the life cycle control modalities may be selected by a user based upon known tradeoffs.
