  • Patent number: 9868659
    Abstract: A method of producing purified water in a subsurface environment is provided in which ambient subsurface source water is introduced into and through one or more ultrafiltration membrane units of a subsurface water treatment system and producing thereby an ultrafiltrate substantially free of solid particulates having a largest dimension greater than 0.1 microns. An electrochemical unit in fluid communication with at least one ultrafiltration membrane unit provides an antifoulant solution. An ultrafiltrate-rich backwash fluid and at least a portion of the antifoulant solution are delivered to at least one non-producing ultrafiltration membrane unit during a backwash cycle. A flux of source fluid through each of the ultrafiltration membrane units of less than thirty gallons per square foot per day limits the need for backwash cycles. A reduction in the number of backwash cycles enhances system autonomy and useful life, and limits the need for intervention for maintenance and component replacement.

  • Patent number: 9871396
    Abstract: Systems and methods for controlling the charge of an energy storage device include determining an estimated energy production prediction for an energy source from a present time to a target time by which an energy storage device is desired to reach a top of charge (TOC) energy level when being charged by the energy source. An available amount of energy for storage at the energy storage device if the energy storage device is charged from the energy source at a first charge rate from the present time until the target time is determined. A present charge rate for the energy storage device is controlled to be the first charge rate when the available amount of energy is less than the energy storage capacity of the energy storage device and to be a second charge rate less than the first charge rate when otherwise.

  • Patent number: 9872403
    Abstract: The present disclosure is directed to an electrical cabinet for an electrical assembly for a wind turbine. The electrical cabinet has one or more walls that define an internal volume having one or more electrical components configured therein. One or more of the walls includes an inner panel and an outer panel mounted to the inner panel. The inner panel includes an inner vent and the outer panel includes an outer vent. Further, the panels are arranged together so as to define a flow path between the inner and outer vents. Thus, during normal operation, air is directed from outside of the electrical cabinet to the internal volume of the electrical cabinet via the flow path so as to cool the one or more electrical components. Further, during a fault event, gas is permitted to exit the internal volume of the electrical cabinet via the flow path.

  • Patent number: 9869205
    Abstract: A housing for retention of the outer race of a bearing of a gas turbine engine includes an arrangement of spring fingers that yields a lightweight housing capable of withstanding very high radial loads combined with very high torsional windup and axial thrust load. Controlled circumferential gaps on both sides of each spring finger limit the deflection and self-arrest the distortion of the housing. An axial gap is created on the aft end by a portion of the spring finger beam structure that opposes an axial face of the housing and limits the axial distortion. A radial gap created between interface hardware of the housing and the inner retention housing also acts to retain the spring finger housing under load in a radial direction.
