Abstract: An extrusion system for separating particulates entrained in wash water, e.g. from harvesting tuberous produce, includes a settling tank configured to receive a flow of particulated water. A diffuser suspended within the tank converts the flow of particulated water into multiple transverse flows to avoid churning settled particulates. A particulate filter fixed within the tank includes a central channel surrounded by a cylindrical array of cantilevered parallel vertical blades. The channel directs the flows below the blades, causing dynamic movement of the blades as the particulated water rises therebetween to trap particulates along boundary layers, promote particulate settling by gravity, and allow clarified water to rise to the top of the tank. A sensor detects settled particulate reaching a predetermined setpoint, and in response the system actuates an auger and opens a pinch valve to force concentrated particulate from the bottom of the tank.

Abstract: A camshaft assembly for a vehicle valvetrain having first and second engine valves includes a camshaft, and a first camshaft cartridge axially displaceable along the camshaft and including a plurality of first cam lobes configured to selectively impart movement to the first engine valve. A second camshaft cartridge is axially displaceable along the camshaft and includes a plurality of second cam lobes configured to selectively impart movement to the second engine valve. An actuator is configured to axially displace the first camshaft cartridge along the camshaft. A coupling is between the first camshaft cartridge and the second camshaft cartridge. Axial displacement of the first camshaft cartridge selectively imparts movement to the second camshaft cartridge for axial displacement of the second camshaft cartridge.

Abstract: An intake manifold assembly for a vehicle engine includes an intake manifold housing defining a main chamber having perimeter walls and an open upper end; a charge air cooler (CAC) positioned in the main chamber and having an upper cover plate defining a sealing flange; and an integrated positive crankcase ventilation (PCV) system. The PCV system includes a PCV chamber integrally formed into an upper surface of one of the perimeter walls, the PCV chamber having an open upper end; a PCV port integrally formed with the intake manifold housing and in fluid communication with the PCV chamber; a distribution port defined by a wall of the PCV chamber and in fluid communication with an outlet plenum of the intake manifold. Upon securing the CAC to the intake manifold housing, the CAC sealing flange provides a sealed closure for the intake manifold main chamber and the PCV chamber.

Abstract: A lubricant heat exchanger may include a mounting portion and a heat exchanger portion. The mounting portion may be configured to engage a first end of a lubricant filter and may include a fluid passage in fluid communication with the lubricant filter. The heat exchanger portion may extend from the mounting portion and may be configured to at least partially surround a circumferential surface of the lubricant filter. The mounting portion may engage the first end of the lubricant filter and provide fluid communication between the heat exchanger portion and the lubricant filter. The heat exchanger portion may include a fluid inlet and a fluid outlet. The fluid inlet and outlet being fluidly isolated from the lubricant filter.

Abstract: Techniques for filtering light include, along a central optical axis, an entrance window; a first polarizer, a narrowband polarization-changing material, a second polarizer, and an exit window. The optical paths through the filter are substantively unscattered and pass through unstressed components between the polarizers. The polarization-changing material changes polarization for a narrow wavelength band on the order of about 0.01×10?9 meters and does not condense on optical windows and polarizers during the operational lifetime. An aspect ratio, defined by a distance from the entrance window to the exit window divided by an optical aperture for the entrance window, is less than 4/1. This filter thus transmits light substantively unattenuated in the narrow wavelength band up to a maximum acceptance angle greater than 5 degrees. Combined with optics and imaging detectors, it is suitable for wide area surveillance, including daylight surveillance for combustion like forest fire and missile plume.
