  • Patent number: 9291637
    Abstract: A system for damping a wind vane includes a damping assembly configured to utilize eddy currents to dampen rotational motion of at least a portion of the wind vane. The damping assembly may provide damping of the wind vane to accommodate for sudden changes in wind speed and/or direction while allowing the wind vane to maintain accurate measurements and response in low wind conditions. The damping assembly may reduce the wind vane's susceptibility to oscillation, thereby improving accuracy of the wind vane.

  • Publication number: 20140311750
    Abstract: A method of selecting an injectate for recovering liquid hydrocarbons from a reservoir includes designing a plurality of injectates, calculating a net present value of each injectate, and selecting a candidate injectate based on the net present value. For example, the candidate injectate may be selected to maximize the net present value of a waterflooding operation.

  • Publication number: 20140163904
    Abstract: Generally, a system and method consistent with the present disclosure may provide a relatively low cost, relatively robust data acquisition and analysis system useful for condition-based maintenance. The system may be useful for condition-based maintenance in industrial applications, e.g., of equipment and/or machinery. The industrial monitoring system may be used, for example, to monitor a condition of rotating machinery, e.g., a wind turbine. The system and method may include data analysis that may be useful for anticipating a need for maintenance, repair and/or replacement of one or more components.

  • Publication number: 20140137665
    Abstract: A bearing assembly for an anemometer configured to provide thrust and axial load protection and reduce exposure to potentially degradative debris and/or contaminants. The bearing assembly includes a first shaft and a second shaft and bearings, wherein the bearings are configured to rotate about at least the first shaft while enclosed within a portion of the second shaft. The second shaft is configured to isolate the bearings from any air flow through the anemometer and debris and/or contaminants carried therewith. The bearing assembly further includes a damping member configured to reduce forces imparted upon the bearings, thereby providing protection and preventing premature damage to the bearings from loads.

  • Patent number: 4497310
    Abstract: There is disclosed an improved flue box assembly for use in conjunction with a heating plant, the flue box having a housing with an interior diametric opening substantially greater than the exhaust gas inlet to and outlet from the interior of the housing, and provided with a damper plate being pivotally mounted within the housing and movable between an open position and a closed position, the damper plate further having a flue opening positioned therein, the improvement consisting of a cap pivotally mounted on the housing adjacent the outlet opening thereof, the cap adapted to pivotally move between a closed position occluding the outlet opening of the housing and an open position leaving the outlet opening unobstructed, and adjustable counterbalancing means associated with the cap for adjusting the relative pressure necessary to move the cap into an open and closed position respectively in relation to the force exerted by flue gases escaping through the outlet opening of the housing, thus providing for impro
