  • Crankshaft assembly for variable stroke engine for variable compression
    Patent number: 4887560
    Abstract: A crankshaft carried crankpin carries an eccentric interposed between the crankpin and the slider of a yoke type engine. The eccentric carries a gear to permit rotatable adjustment to be imparted to the eccentric about the crankpin axis. Positioning of the eccentric includes the use of a gear train. A gear set in the gear train has displaceable gears carried by a carrier responsive to engine control means. The movable gear set serves to accelerate or decelerate the rotational speed of a pair of shaft mounted driven gears to momentarily alter their rotational speed so as to in turn rotate the eccentric mounted gear to reorientate the eccentric to the crankpin. Such relocating of the eccentric serves to alter the piston stroke between high and low compression ranges.

  • Centrifugal flotation apparatus
    Patent number: 4874357
    Abstract: The apparatus includes a powered bowl assembly having a tubular shaft journalled within a base of the apparatus. A pressurized air flow is discharged into slurry in the bowl assembly via a circular array of bubble generators. An impellor discharges the slurry outwardly against an upwardly inclined annular surface of the bowl assembly to cause the slurry to merge upwardly with the streams to promote flotation. Slurry within the bowl assembly forms a vortex with particle flotation forming a froth layer inwardly of a slurry vortex. The froth exits the bowl assembly upwardly past a barrier partially closing the bowl assembly. Heavier gangue particles exit via an outlet about the bowl assembly periphery. A collector shroud is partitioned to receive the froth and the heavier waste material. A modified form of the apparatus includes an independently powered bowl assembly and impellor.
