Abstract: An automatic variable speed eductor recirculation system for metal recycling furnaces having a delacquering chamber and a separate heating chamber. The system includes a recirculation duct between the two chambers, an eductor in the duct, a variable speed blower forcing motive gases into the eductor creating a Venturi that draws VOC's from the delaquering chamber through the eductor, and an infrared opacity sensor proximate the eductor that measures the transparency level of the gases in the eductor. An electronic controller automatically adjusts the blower speed to control the eductor Venturi based upon the transparency level measurements of the opacity sensor.

Abstract: A hydraulic system (e.g., of an aircraft or other vehicle) includes a pump, a pressure line coupled to the pump and configured to distribute pressurized hydraulic fluid, and a return line configured to return hydraulic fluid to a reservoir. The hydraulic system also includes an auxiliary leakage valve coupled to the pressure line, to the return line, and to an actuator. The auxiliary leakage valve is configured to receive a control signal and, based on the control signal, selectively open a restricted fluid path. The restricted fluid path couples the pressure line to the return line to allow a restricted amount of the hydraulic fluid to flow from the pressure line to the return line.

Abstract: A hydraulic cooling system for a heavy-equipment machine, with the heavy-equipment machine including a frame supported on the ground by a ground-drive assembly, a cab extending upward from the frame, and an attachment tool for performing work. The hydraulic cooling system comprises a main housing and a cooling assembly housed at least partly within the main housing, with the cooling assembly being configured to reduce a temperature of hydraulic oil flowing through the hydraulic cooling system. The hydraulic cooling system further comprises an attachment assembly for attaching the main housing to the cab of the heavy-equipment machine. The main housing is configured to extend rearward from the cab.

Abstract: A vehicle comprising a hydraulic fluid reservoir, a hydraulic fluid pump, a hydraulic filter, a sensor, and a vehicle control unit. The hydraulic fluid reservoir may have a bottom portion filled with hydraulic fluid and a top portion filled with air. The hydraulic fluid pump may be hydraulically coupled to the hydraulic fluid reservoir so as to draw hydraulic fluid from the hydraulic fluid reservoir. The hydraulic filter may be hydraulically coupled to the hydraulic fluid reservoir so as to filter debris from the hydraulic fluid entering the hydraulic fluid reservoir. The sensor may be in communication with the vehicle control unit where the sensor is configured to measure a variable indicative of a failure status of the hydraulic filter and communicate the variable to the vehicle control unit. The vehicle control unit may be configured to derate the hydraulic fluid pump to a first degree when the variable indicative of the failure status of the hydraulic filter is above a first threshold and configured to derate the hydraulic fluid pump to a second degree when the variable indicative of the failure status of the hydraulic filter is above a second threshold.

Abstract: A return filter is provided in a tank, for removing bubbles from hydraulic oil before returning the hydraulic oil to the tank. A vortex forming portion that includes a spiral-shaped blade member is provided in an outflow portion that has a substantially cylindrical shape and communicates with a hollow portion of a filter element. Thus, a vortex forms in the hydraulic oil flowing through the outflow portion and bubbles contained in the hydraulic oil are collected.

Abstract: The invention relates to a high-pressure hydraulic fluid screening element (1) for inserting into a hydraulic line or into a hydraulic connection of a hydraulic device, having an annular main body (2), which is aligned with respect to its axis of rotation (9) in a longitudinal direction (5). The outside diameter of the main body (2) is greater than its axial length. The inner cross section of the main body (2) is covered over by a screening region (3), which is provided with a multiplicity of apertures (4). In this case, the main body (2) and the screening region (3) are produced integrally by the powder injection-molding process.
