Abstract: In one embodiment of the invention, a solenoid is provided that is energizable by an electric current and includes: a pole piece, which is configured from a magnetizable pole material; an armature, which is movable when an electric current is passed through the solenoid; and an electromagnetic coil. A current passes through the coil when the solenoid is energized; the coil includes a central opening, wherein the pole piece is at least partially located. The diameter of the central opening may be less in a mid region than at upper and lower ends of the coil. At least one of either the upper or lower inside ends of the central opening of the coil may be beveled or contoured with a radius. The magnetic flux generated when the coil is energized has an enhanced flow path reducing the saturation in the transitional area at the upper and lower inside ends of the central opening as compared to a standard coil.

Abstract: A refrigerated display case is provided that includes a display chamber for displaying product. The display chamber includes a product tray for supporting the product. A cooling chamber is arranged beneath the product and is in communication with a surface of the product tray. The cooling chamber is sealed from the display chamber, in one example, and includes a cooling coil. A fan is in communication with the cooling chamber and cooling coil. The fan circulates a cooling flow through the cooling coil. The cooling flow moves across the surface and absorbs heat from the product tray by convection. The cooled product tray removes heat from the product by conduction.

Abstract: A device and method is disclosed for allowing a combine operator, from the operator's station, to automatically transversely position a pinch-point of a concave relative to a rotor of a combine in accordance with the clearance spacing set between the concave and the rotor, thereby minimizing operator effort without sacrificing combine performance.

Abstract: A device and method is disclosed for effecting movement and extending the clearance spacing between a rotor of a combine and a concave to allow for easy removal of lodged material. The apparatus and method additionally provide a reduction in rotor actuation motor torque and an increase in rotor mechanical advantage. Finally, the apparatus and method provide a travel limit to prevent a concave from being raised into, and having contact with, a rotor of a combine.

Abstract: A preferred embodiment EGR valve permits exhaust gas to be induced into the intake line downstream of the compressor, while minimizing the need to reduce the size of the turbocharger. The preferred embodiment EGR valve exploits variations around the mean pressure in the EGR passage created by the engine cycle by selectively opening when the pressure in the EGR valve exceeds the pressure in the intake line. Thus, exhaust gas is recirculated even when the engine is running near torque peak. The preferred embodiment EGR valve also exploits the higher mean pressure in the exhaust line relative to the intake line at higher engine speeds by remaining open, in order to minimize the energy consumed in opening and closing the EGR valve.

Abstract: The present invention is directed toward a lift pump mounting bracket for an electronic control module cooler. In a preferred embodiment of the present invention, the lift pump is mounted directly to the ECM cooler by means of a pair of brackets which engage frustoconical-shaped grommets on either end of the lift pump. The grommets provide vibration dampening for the lift pump, while mounting the lift pump directly to the ECM cooler provides a convenient place for such mounting and, typically, ease of access should the lift pump need to be serviced. The frustoconical shapes of the mounting grommet allow the lift pump to be removed upon the disassembly of only a single one of the pair of mounting brackets, thereby making disassembly quicker and more convenient.

Abstract: An exhaust aftertreatment system for use with an internal combustion engine includes at least one leg having a multi-stage NOx adsorber, with each NOx adsorber stage corresponding to a different temperature range of NOx adsorption. In a multi-pass aftertreatment system, a manifold has at least one inlet and a plurality of outlets. A plurality of legs are connected with a respective manifold outlet. Each leg has a NOx adsorber therein. At least one valve is positioned in association with at least one leg for at least partially opening and closing the at least one leg.

Abstract: The method of treating a fuel lean exhaust containing NOX and SO2 includes splitting the exhaust into major and minor portions for flow through multiple flow paths each of which contains a particulate trap and an absorber containing a NOX oxidation catalyst and a nitrate absorbent. The major portion is passed through a flow path in the lean state at a first temperature to convert the NOX to nitrate and the SO2 to sulfate. After the first period of operation flows are switched so that one flow path receives a minor exhaust portion for a second period of time during which fuel is injected into that flow path along with diversion of a portion of exhaust from another flow path through a bypass.

Abstract: A control system for controlling exhaust gas recirculation in an internal combustion engine. The output of a throttle position sensor is used as an input to two parallel filters. The first filter is a lag-lead compensated filter which functions as a differentiator, producing an output proportional to the instantaneous rate of change of the throttle position.. The second filter is a fixed-rate tracking filter which generates a tracking signal that tracks the input signal. The tracking signal, however, cannot vary by more than a maximum predetermined rate. The output of the second filter is the difference between the input signal and the tracking signal. The outputs of the two filters are summed and applied to a hysteretic comparator, which turns the EGR valve off when the sum exceeds an upper threshold and turns the EGR valve back on when the sum has decayed below a lower threshold.
