Abstract: FUEL CONTROL SYSTEM WITH CALIBRATION LEARNING CAPABILITY FOR MOTOR VEHICLE INTERNAL COMBUSTION ENGINE          Abstract of the Disclosure:         A memory type fuel control system provides a fuel supply rate trimmed by a trim factor recalled from memory at an address determined by predetermined engine operating conditions.  The engine exhaust gas oxidizing/reducing conditions are sensed by exhaust gas sensors.  A sampling circuit recurrently samples and momentarily stores the engine operating conditions in a short term memory to form a history of those conditions extending back at least by the amount of the engine transport delay time.  At a later time, the exhaust gas oxidizing/reducing conditions sensed by the exhaust gas sensor is sampled, the engine operating condi-tions that produced the sampled exhaust gas condition are recalled from the short term memory, a new trimming value is determined for the recalled vehicle conditions which more closely produce a desired oxidizing/reducing condition, and such value is inserted in the main memory at the address determined by the recalled conditions.  Such trim factor is then available for recall and use as the trimming factor when the engine is next operated under such conditions.

Abstract: ABSTRACT OF THE DISCLOSURE                This invention relates to an improved electrically heated sprue bushing for injection molding.  The sprue bushing has a central runner passage for conveying melt from the molding machine or manifold to the cavity.  The runner passage extends through an elongated inner core portion having an undulating outer surface in the form of a helical ridge with a rounded cross section.  A single element electrical heating element with a helical configuration is located over the core portion and an outer shell portion is cast over them to form the sprue bushing as an integral unit.  The inner core portion is formed of a high strength material such as ? beryllium nickel alloy and the outer shell portion is formed of highly conductive material such as a beryllium copper alloy.  The coils of the heating element are separated from each other and threaded in the opposite direction to the helical ridge on the outer surface of the core portion.  This allows the highly conductive material to surround the heating element with no insulative air gape.  Thus heat is rapidly conducted away from the heating element preventing burn out, and the undulating surface provides a maximum of surface contact for heat transfer to the core portion.  The integral structure provides increased strength to withstand the repeated impact loading which allows the wall thickness of the inner portion to be reduced.

Abstract: ABSTRACT     This invention relates to an air flow diverter for reducing the aerodynamic drag of a vehicle having a front roof portion and a rear roof portion at a higher level than the front roof portion.  The diverter comprises a plurality of superimposed laminar elements,the lowermost of which is adjacent the front roof portion of the vehicle.          Each other laminar element has its front edge disposed in proximity to the laminar element below it, defining therewith a transverse entrance slit.  Each pair of adjacent laminar elements furthermore define a divergent duct downstream of the respective entrance slit.          In operation of the vehicle, a part of the air flow passes through the divergent duct, increasing in pressure  to establish a high pressure region downstream of the diverter, substantially fixed relative to the vehicle, which encourages the deflection of the principal part of the air flow over the roof and sides of the vehicle-when the vehicle is in motion.

Abstract: HIGH RESOLUTION ANALOG TO DIGITAL CONVERTER    ABSTRACT    The disclosed high resolution analog to digital converter circuit has an integrator circuit responsive to the unknown analog input.          The integrator circuit is operated for a fixed period of time during which, on a periodic basis, a predetermined charge is dumped from the integrator circuit capacitor.  A counter is incremented each time a dump occurs and the counter value at the end of the fixed period is related to the high order digits of the digital value for the unknown analog signal.  A digital number corresponding to the output level of the integrator is determined by a successive approximation circuit both before and just after the fixed period.  The difference between the two values determined by  the successive approximation circuit is related to the low order digits of the digital value for the unknown analog signal.           (1)
