Abstract: A carbureting type fuel metering apparatus has an induction passage into which fuel is fed by several fuel metering systems among which are a main fuel metering system and an idle fuel metering system, as generally known in the art; engine exhaust gas analyzing means sensitive to selected constituents of such exhaust gas creates feedback signal means which through associated transducer means become effective for controllably modulating the metering characteristics of the main fuel metering system and the idle fuel metering system; reciprocating type solenoid control valve means is employed for modulating actuating pressure applied to the structure of the main fuel metering system and idle fuel metering system in order to achieve the desired metering functions.

Abstract: A bistable magnetic wire has an electrically conductive wire coiled thereabout as to form, generally, a magnetic wire assembly which is situated in spaced proximity to a magnet; the opposite ends of the conductive wire are electrically connected to related output or receiving apparatus; a shield or shutter arrangement operated generally between the magnetic wire assembly and the magnet serves to cause the magnetic wire to be at times placed under the influence of the magnetic field of the magnet thereby resulting in the magnetic wire changing from one stable state to another state and in so doing inducing a voltage into the conductive wire to produce a pulse across the said opposite ends thereof.

Abstract: An ignition distributor for an internal combustion engine has a drive shaft adapted to be driven in accordance with engine speed, a pulse generating rotor coaxial with said shaft and adapted to be angularly adjustable relative thereto, and a single flyweight adapted for rotation in accordance with the speed of rotation of said drive shaft and operatively connected to said rotor for angularly adjusting said rotor generally in accordance with the speed of rotation of said drive shaft.
