  • Process to produce light products and fuel oils for conventional use from heavy metal- and sulfur-rich crude oil residues
    Patent number: 4792389
    Abstract: The invention describes a process for producing light products, such as engine and diesel fuels, and fuel oils for conventional use by thermal conversion of heavy metal- and sulfur-rich-crude oil residues. Thermal cracking of the residues is done by mild cracking in several stages, where the residue remaining after separation of the conversion products of the preceding stage is fed to the respective subsequent stage.

  • Battery cell cooling system
    Patent number: 4007315
    Abstract: Multi-cell battery cooling is accomplished by cooling elements immersed in the cell-top electrolyte. The elements have high heat conductivity and electric resistance. The cooling medium has low electric resistance. Various configurations of circulatory flow paths provide various utilizations for the medium beyond that of cooling the cells.
