    摘要： A system and method for reducing corrosion in a fluid dynamic bearing is disclosed. In one embodiment, a fluid dynamic bearing comprising a rotor portion and a stator portion is formed. In addition, a corrosion inhibitor containing lubricating fluid is provided between the rotor portion and the stator portion of the fluid dynamic bearing, wherein the corrosion inhibitor containing lubricating fluid does not react with either the rotor portion or the stator portion of the fluid dynamic bearing.

    摘要： Embodiments disclosed herein include devices and methods for gripping electrical components. The electrical device gripping tool may include a rotating handle, a cam assembly, and a body. The rotating handle may be attached to the assembly and the cam assembly may include a cam holder that fits over the cam to connect the rotating handle to the body. Furthermore, the body may include a first body half and a second body half that are each separately coupled to the cam such that the first body half and the second body half slide towards each other and slide away from each other with respect to a rotation of the rotating handle. In addition, shields are optionally attached to the first and second body half such that they assist in the removal of the electrical device without its terminals making contact with the containment box.

    摘要： The invention apparatus and method is practiced in large steam surface condensers and in one aspect comprises relatively narrow horizontal trays installed between the vertical tube bundles to drain the condensate from the upper bundle around the lower ones and thereby improve the heat transfer coefficient of the lower bundle(s). A second aspect of the invention apparatus comprises relatively narrow horizontal trays installed slightly below the lowest bundle to improve reheating of falling condensate up toward the saturation temperature of the condenser thereby reducing subcooling and the level of dissolved oxygen in that condensate. A third aspect of the invention apparatus comprises a partial hood retrofitted at the top of the central tube sheet air off-take entrance which is a unique element of the starburst/core pipe condenser design to thereby improve the air removal capability and consequently the performance of the condenser.
