Abstract: Novel gasoline compositions comprising gasoline and dissolved or dispersed therein small quantities of from about 0.5 to about 100 parts by weight of a driveability-enhancing fluorine-containing polymer per million parts of gasoline will, after carburetion in a multicylinder automobile engine, plate out a fluoropolymeric deposit on the interior surfaces of the intake manifold of the engine thereby establishing on the manifold metal surface a coating of low wettability by any hydrocarbon gasoline component, either aliphatic or aromatic, and significantly improving the driveability performance of the engine. The driveability-enhancing fluorine-containing polymers useful in the gasoline compositions of the invention are characterized in that they must (1) have a critical surface tension of <17 dynes/centimeter at 25.degree. C, (2) have a high contact angle of at least 40.degree. to toluene at 22.degree.

Abstract: The present invention relates to a fuel dispensing nozzle made of plastic material and having means for conducting an electrical charge from the inlet of a receiving vessel to the source of the liquid connected to said nozzle.

Abstract: A liquid fuel vaporizing device for an internal combustion engine wherein a heat pipe containing a heat transfer fluid having a boiling point up to 400.degree. C is disposed so that the heat transfer fluid transfers heat from a heat-receiving zone to a heat-discharging zone. The liquid fuel is vaporized in the heat receiving zone after being mixed with the main stream of air.

Abstract: An apparatus for rapidly conditioning wax samples and a method for determining the oil content of said samples with a nuclear magnetic resonance analyzer are described. A molten wax sample is collected in a sample holder. The holder is then placed in a temperature equilibration chamber where the molten wax is rapidly cooled at a temperature of about 25-33.degree.F with a cold gas stream from a vortex tube. The sample is then heated to a pre-selected equilibration temperature for a preset time at which point the sample is removed from the equilibration chamber. The sample is placed in the analyzer where the nuclear magnetic resonance value of the sample is determined. The sample is removed from the analyzer and weighed. Finally the oil content of the wax sample is obtained from a previously developed correlation between the oil content and the nuclear magnetic resonance value of various wax samples.

Abstract: A system is disclosed for preventing gasoline vapors contained in air vented from gasoline storage tanks from entering the atmosphere, which includes a conduit to pass gasoline vapor-laden air to a bed of adsorbent for gasoline and, when the adsorbent approaches saturation, subjecting it to back-flushing, with or without heat, to an extent and for a time adequate to remove enough gasoline from the adsorbent to restore it to a regenerated condition, and incinerating the gasoline removed from the adsorbent bed.
