Bilge water reclamation system and process
A system and method for treating and removing hydrocarbon and other contaminants in bilge and ballast water, utilizing a multiple progressive process that chemically and electrically treats-and removes contaminants. Wastewater, received by a sump, is transmitted to a holding tank and treated, over a period of time while-influent wastewater continues off loading. The wastewater is pumped to an oil / water separator tank that decants free-floating oil from the wastewater to an oil retention tank. The wastewater then undergoes an electrocoagulation process where emulsions are broken and compounds that further aid treatment are created. The treated water flows to a retention / separation tank where contaminant particles coalesce and separate. Water is decanted and transferred to a clean water holding tank through an ozone injection system and an activated carbon filter. Treated water is recirculated until it exits the system meeting discharge limits for organics and metals allowing release into the environment.

Air system architecture for a mid-turbine frame module
A mid-turbine frame is disposed between high and low pressure turbine assemblies. A secondary air system is defined in the mid-turbine frame (MTF) to provide cooling to the turbine section of the engine. The secondary air system may be used to cool and pressurize seals to assist with oil retention in bearing cavities. The temperature gain of the secondary air may be reduced by flowing the secondary air through one or more external lines and then generally radially inwardly through air passages defined in the MTF.

Manufacturing method that uses laser surface transformation to produce new and unique surface profiles for rotating bearings
ActiveUS20060138100A1Semiconductor/solid-state device manufacturingPhotosensitive material processingOil retentionEarth surface
A laser ablation method is used to polish a bearing surface of an automotive crankshaft. A laser ablation device generates a laser according to parameters such as wavelength, pulse duration, pulse repetition rate, and beam quality. The laser is applied to the surface of a rotating engine component, such as a crankshaft, as the component is rotated in order to polish the surface according to the parameters. The laser substantially improves tribological performance of the bearing surface by changing the waviness and form of the surface profile. Further, oil-retention reservoirs are formed in the surface. As a result, the friction coefficient of the crankshaft surface is reduced while the roughness of the crankshaft surface is maintained, reduced, or increased.
