  • Process of treating aluminum-containing fused slag
    Patent number: 4732606
    Abstract: A method of recovering a metallic aluminum from an aluminum-containing slag of an aluminum smelting process. In this method, the slag is crushed a number of times with each crushing product being separated by a screening off removing the metallic aluminum before the next crushing stage. Water-soluble components are then removed from the slag by leaching and the leaching solution is evaporated to enable recovery of these components.

  • Power distribution gearing for double helix extruders
    Patent number: 4297917
    Abstract: A driving gear assembly for a double helix extruder. The assembly includes a multiple power path from a transmission gear to produce synchronism in the extruder helix shafts. The structure of the gearing enables a simple adjustment of the proper mesh of the extruder helices when mounting the gearing by mere disengagement and re-engagement of a (normally not disengageable) tooth coupling.
