Patent number: 8986552
Abstract: A filtration and monitoring system. An inlet pipe provides fluid to a filter block chamber and has an inlet valve located therein configured to shut off the flow of the fluid through the inlet pipe. A filtered fluid conduit fluidically connects the filter block with the monitoring device. The outlet axis of the outlet pipe in the filter chamber is offset from the inlet axis of the inlet pipe such that the fluid undergoes a change of direction while passing through the filter block chamber thereby causing turbulent flow within the filter block chamber to reduce the buildup of filter cake on the filter element. Closing the inlet valve block, results in a back-flushing flow of fluid through the filter element from a pressure accumulator located in the filtered fluid conduit.

Patent number: 8987402
Abstract: A novel polycrystalline stoichiometric fine SiC fiber substantially free of impurities is produced using a novel pre-ceramic polymer. The pre-ceramic polymer is prepared by reacting a mixture of chlorodisilane, boron trichloride, and a vinyl chlorodisilane with an excess of hexamethyldisilazane to form the pre-ceramic polymer resin, which may then be melt-spun, cured, pyrolyzed and heat-treated to obtain the finished SiC fiber. The manufacturing process for the production of the fine SiC ceramic fiber allows for flexibility with respect to cross-linking, in that low-cost thermal treatments may replace more complex methods, while obtaining fibers with improved materials properties as compared to currently available SiC fibers.

Patent number: 8987629
Abstract: A process for closing an opening in a surface of a component, and components formed thereby. The process entails forming a channel in the component surface so that the channel at least partially surrounds an opening at the component surface. An alloy is then deposited in the channel to form a crack-free deposit in the channel. A step is then machined that intersects the opening and is at least partially formed in the deposit. The step defines a recess that is at least partially surrounded by a peripheral portion of the deposit and has a surface recessed into the component surface. A cap is placed in the recess and welded to the peripheral portion of the deposit to define a weld joint that completely closes the opening. The surface of the weld joint is then machined to form a machined surface that is substantially flush with the component surface.

Patent number: 8985088
Abstract: Various systems and method for controlling exhaust gas recirculation (EGR) in an internal combustion engine are provided. In one embodiment, a method includes injecting fuel to a subset of cylinders that includes less than all cylinders of a first cylinder group to obtain a target EGR rate. The first cylinder group provides exhaust gas through an exhaust gas recirculation (EGR) passage structure fluidly coupled between the first cylinder group and an intake passage structure. The method further includes injecting fuel to at least one cylinder of a second cylinder group. The second cylinder group provides substantially no exhaust gas through the EGR passage structure.

Patent number: 8988238
Abstract: Systems and methods are provided for monitoring operating machinery, acquiring data regarding characteristic behavior of the machinery being monitored, and processing of the data to determine and indicate when significant deviations from normal operating conditions are occurring that represent maintenance initiating or failure mode events. The method includes learning what normal operating conditions are for a machine of interest by acquiring data during observed normal operation, then calculating detection threshold values based on the acquired data. Finally, real-time monitoring of the machinery of interest during operation is employed, with alarms triggered upon occurrence of a previously-defined number of occurrences of behavior exceeding parameters associated with normal operation behavior.

Patent number: RE45431
Abstract: A battery load leveling system for an electrically powered system in which a battery is subject to intermittent high current loading, the system including a first battery, a second battery, and a load coupled to the batteries. The system includes a passive storage device, a unidirectional conducting apparatus coupled in series electrical circuit with the passive storage device and poled to conduct current from the passive storage device to the load, the series electrical circuit coupled in parallel with the battery such that the passive storage device provides current to the load when the battery terminal voltage is less than voltage on the passive storage device, and a battery switching circuit that connects the first and second batteries in either a lower voltage parallel arrangement or a higher voltage series arrangement.
