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: A vehicle having an engine with a carburetor supplying fuel and having a variably positionable throttle valve, has vacuum responsive motor means operatively connected to the throttle valve for at times closing the throttle valve so as to govern the maximum speed of the engine associated with the vehicle; a variably positionable vent or valving means controls the amount of ambient air being bled into the vacuum responsive motor means in order to thereby determine when such vacuum responsive motor means will be effective to control the position of the throttle valve; and electronic control and actuating means are effective to sense the speed of the engine and actuate the venting or valving means in response to such sensed speed in order to thereby vary the degree of ambient air bleed.

Abstract: A carburetor having an induction passage with a throttle valve therein has a fuel discharge port arrangement opening into the induction passage generally in the vicinity of an edge of the throttle valve so that as the throttle valve is more nearly opened the edge of the throttle valve, generally, traverses the discharge port arrangement as to effectively increase the functional flow of the discharge port arrangement and thereby effectively increase the rate of flow through the discharge port arrangement; a ledge-like surface situated generally in the induction passage and generally upstream of the discharge port arrangement results in an increase in turbulence of the medium flowing through the induction passage and a better atomization of the fluid flowing from the discharge port arrangement.

Abstract: An accelerating pump system is shown having a chamber into which fuel from a fuel reservoir of fuel bowl is drawn and then, when and as required, ejected, as by a displaceable diaphragm within said chamber, into a passage leading to accelerating fuel nozzle structure for discharge into the induction passage of the related carburetor or fuel metering means; a vent passage serves to communicate between the fuel reservoir and the chamber as to enable a portion of the fuel within the chamber to be returned to the fuel reservoir when the diaphragm is being displaced for ejecting fuel into the said passage; a thermostatic valve serves to preclude such communication between the fuel reservoir and the chamber except when the fuel temperature (employed as an indicia of engine and indirectly ambient temperature) within the chamber attains a predetermined relatively elevated temperature.
