  • Patent number: 4608951
    Abstract: This invention relates to improvements in engines of the reciprocating piston type, especially reciprocating piston internal combustion engines suitable for stationary and non-stationary uses. The pistons of the engine are operatively connected to the drive shaft of the engine via an elongated gear-roller gear pinion mechanism. In association with a cylinder-piston unit of the engine there is provided a roller gear pinion, engaged with the drive shaft such that rotation thereof rotates the drive shaft. An elongated roller gear is pivotally connected via an end to a piston, and the opposite open end of said elongated roller gear is meshed with the roller gear pinion. The elongated roller gear is guided through a path via appropriate mechanism which maintains continuous contact between said gears such that reciprocation of the piston within a cylinder produces rotation of the drive shaft.

  • Patent number: 4608153
    Abstract: A process wherein a feed comprising an admixture of liquid hydrocarbon compounds which includes a polynuclear aromatic hydrocarbon compound, or compounds (PNA's) is contacted in the presence of hydrogen over an iron catalyst at temperature sufficient to selectively hydrogenate and hydrocrack, or destroy the PNA's of the admixture without excessively hydrogenating and hydrocracking the non-PNA's of said feed. The process is particularly applicable for the removal of PNA's from reformates, processed naphthas, and other hydroprocessed streams or the like to achieve a lower and more favorable distribution of PNA's in a motor gasoline pool, and further to remove PNA's from prime fuels and heavier hydrocarbon mixtures.
