Abstract: An improved engine torque management control that coordinates engine throttle, spark and EGR under predefined highly throttled conditions so as to maximize the fuel economy improvement of EGR without degrading engine performance. Under the predefined conditions, EGR is increased to a level that maximizes the fuel economy improvement without causing combustion instability, and the throttle position and spark timing are controlled to compensate for the anticipated torque loss while increasing volumetric efficiency and reducing pumping losses. During idle and steady state cruising operation, EGR is increased, and engine throttle position is controlled to regulate the estimated engine output torque in accordance with the driver requested output torque. During transient torque increases, throttle control alone is used to regulate the output torque, while in transient torque decreases, the throttle position is maintained and spark timing is used to regulate the output torque.

Abstract: A process for analyzing, decomposing, synthesizing and extracting seismic signal components, such as the fundamental of a pilot sweep or its harmonics, from seismic data uses a set of basis functions. The basis functions may be any of the harmonics or other components derived from the pilot sweep. These basis functions are modulated with the data being analyzed. The resulting data output from the modulation are then low-pass filtered so that the instantaneous amplitude and differential phase of the particular signal component to be synthesized may be computed. Each targeted component is then synthesized and the result subtracted from the remaining data.

Abstract: An automatic document feeder is operable in a simplex, or one-sided, reproduction mode and a duplex, or two-sided, reproduction mode. In the duplex mode, the original document sheets are transported through the feed path only twice and output in the same relative page order in which the sheets were input. By this, 100% productivity can be achieved. The feeder assembly uses two separate feeders, one simplex top feeder and one duplex top feeder, to obtain two pass operation. Alternatively, a single feeder is used that can feed from both the top of the stack or from the bottom of the stack depending on the mode of reproduction. A controller allows selection between the simplex and duplex modes and controls the feeding assembly based on the selection.

Abstract: An arbor for a guided circular saw has three symmetrical lobes. The lobes have end regions with profiles which follow an arc centered on an axis of rotation of the arbor. The lobes have driving regions with profiles which follow the arc of a circle centered in an opposing lobe. A saw for use with the arbor has an eye with a shape which follows the contour of the arbor. The saw is capable of floating axially along the arbor. The saw and arbor can be used to advantage in sawing machines such as edgers. The arbor provides a much larger saw contact area than do prior art arbors. In one embodiment of the invention the saw is mounted between a pair of spaced apart collars on the arbor. The collars guide the saw but are not tightly clamped to the saw.

Abstract: A temperature measurement system includes, for each of two nuclear steam supply system (NSSS) loops, four temperature sensors each of which provides a value of the temperature of reactor coolant flowing in the NSSS hot leg of the loop; a mechanism for determining, for the hot leg, a first bias value associated with a first pair of the temperature sensors and a second bias value associated with a second pair of the temperature sensors from the value of the temperature of the reactor coolant of each of the temperature sensors; a mechanism for averaging the first bias value and the values of the first pair of the temperature sensors to determine a first average temperature therefrom; and a mechanism for averaging the second bias value and the values of the second pair of the temperature sensors to determine a second average temperature therefrom, whereby two separate average temperatures of the temperature of the reactor coolant are determined for each of the two loops.

Abstract: Internal combustion engine air/fuel ratio control responsive to low voltage operating conditions of an electrical system maintains stable, precise air/fuel ratio conditions under electrical system fault conditions affecting operation of fuel control components including fuel pumps, fuel injectors, and drivers therefor. Electrical system operating voltage is monitored and when a voltage drop below a voltage threshold associated with reliable engine cylinder air/fuel ratio control is diagnosed, the air/fuel ratio smoothly transitions to a reduced engine performance operating mode which, at least for high engine output power requests, limits fueling and airflow to the engine cylinders to a level that may be accurately, reliably supported by the fuel control system components under their reduced electric drive signals. The reduced performance operating mode is maintained while the fault condition persists.

Abstract: A buck regulator provides two outputs via two transformer-coupled inductors each coupled to a respective output capacitor and to a respective diode or switch for allowing current to flow in the respective inductor for charging the respective output capacitor during intervals between pulses of a pulsed input supply. One of the inductors is directly coupled and the other of the inductors is coupled via a further capacitor to the pulsed input supply so that current for charging the respective output capacitors flows in both inductors during the pulses. Each inductor can be tapped, and/or the transformer turns of the inductors are equalized, so that no a.c. voltage appears across the further capacitor and the output voltages can be different. The output voltages can also be stacked or of opposite polarities.

Abstract: An arbor for a guided circular saw has three symmetrical lobes. The lobes have end regions with profiles which follow an arc centered on an axis of rotation of the arbor. The lobes have driving regions with profiles which follow the arc of a circle centered in an opposing lobe. A saw for use with the arbor has an eye with a shape which closely follows the contour of the arbor. The saw is capable of floating axially along the arbor. The saw and arbor can be used to advantage in sawing machines such as edgers. The arbor provides a much larger contact area than do prior art arbors.

Abstract: An electromechanical machine having an improved arrangement for sealing lead wires. A housing structure of the electromechanical machine includes a tubular lead conduit, such as a short pipe section, through which the lead wires extend. A resinous sealing compound, such as an epoxy, is located within the tubular lead conduit. The lead wires are thus potted, and a predetermined degree of isolation is provided between the inside of the machine housing and the ambient environment. Preferably, the inner surface of the tubular lead conduit defines a labyrinthine structure, such as a series of parallel grooves, to further enhance the sealing function.

Abstract: Control of engine speed responsive to a deviation in engine speed away from a target speed is applied selectively under closed-loop airflow control operating conditions, such as idle and coastdown operating conditions in response to analysis of a cause of an engine intake airflow deviation away from a modeled airflow. If airflow deviations are determined to have resulted from variation in internal engine friction away from a nominal friction level, the control is applied. If airflow deviations are determined to have resulted from change in internal engine airflow restriction, such as due to contaminant build-up over a period of engine use, then the control is not applied under closed-loop airflow control operating conditions to avoid overcompensating for such deviations.
