Abstract: ELECTRONIC-FUEL-INJECTION-SYSTEM ENRICHMENT CIRCUIT FOR USE DURING      ENGINE CRANKING         ABSTRACT OF THE DISCLOSURE          An electronic-fuel-injection-system enrichment circuit for use during cranking of an internal combustion engine having a fuel supply controlled by the fuel injection system.  The fuel injection system produces a fuel control electrical signal representative of a quantity of fuel to be injected into the engine.  An enrichment circuit, for use during cranking of the engine to increase the quantity of fuel represented by a fuel control electrical signal, is provided.  This enrichment circuit includes circuit means for generating an enrichment electrical signal having a characteristic which varies with time subsequent to initia-tion of cranking of the engine and circuit means for com-bining the enrichment electrical signal with at least one other electrical signal representative of a fuel quantity to be injected into the engine.  The combined electrical signals produce the fuel control electrical signal.  The variability with time of the enrichment electrical signal during cranking of the engine tends to increase the quantity of fuel represented by the fuel control electrical signal.  The enrichment electrical signal may vary in discrete steps as a function of time.  Subsequent to the start of the engine, the enrichment signal may vary with time in a manner tending to decrease the quantity of fuel represented by the fuel control electrical signal.

Abstract: ASPHALT PAVEMENT RECYCLING APPARATUS          Abstract of the Disclosure Disclosed is a method and apparatus for recycling asphalt concrete roadways by adding little or no new hot mix to the recycled surface.  The apparatus includes means for heating the roadway and applying emulsified asphalt thereto prior to scarifying the heated surface.  The surface is then scarified so as to loosen the heated asphalt.  The scarified material is then treated with asphalt and, if desired, a rejuventaing agent.  They are mixed thoroughly to form a hot mix of asphalt concrete from the old road material.  The rejuvenated hot mix is leveled by means of screws and then compacted substantially by a vibrating screed.  The screed has a continuous bottom plate and a plurality of relatively movable upper sections which are connected by turnbuckles adapted to be adjusted for bending the bottom plate of the screed to conform to the contour of the road crown.  Final compaction of the road surface is obtained by rollers.
