  • Decomposition method for producing submicron particles in a liquid bath
    Patent number: 6746511
    Abstract: A continuous method of manufacturing a liquid dispersion containing submicron metal or metal compound particles inside a liquid bath. A metal-containing fluid with carrier gas mixture is bubbled through the liquid bath and predetermined conditions in the bath cause the fluid to decompose to form the submicron sized metal or metal compound particles in the liquid.
    Type: Grant
    Filed: July 3, 2002
    Date of Patent: June 8, 2004
    Assignee: Inco Limited
    Inventors: Eric B. Wasmund, Richard S. Adams, John Ambrose, Armen Markarian, Dirk Naumann, Lloyd Timberg, Rinaldo Stefan

  • Method of preparing photoconductive pigments by treating .alpha.-form metal-free phthalocyanine to a liquid jet interaction
    Patent number: 5168022
    Abstract: In a process for preparing a photoconductive pigment having a small particle size, a polymorph of a pigment is produced by a conversion process wherein a seed amount of the desired polymorph of the pigment and a larger amount of another polymorph of the pigment are subjected to a liquid jet interaction process.

  • Processes for the preparation of phthalocyanines for electrophotography
    Patent number: 5100752
    Abstract: A process for the preparation of x-metal free phthalocyanine which comprises (i) initially preparing a mixture of alpha- and x-metal free phthalocyanines from alpha-phthalocyanine with a grinding or mixing device, (ii) converting the above mixture to x-metal free phthalocyanine by the addition of an organic solvent, (iii) separating the x-metal free phthalocyanine therefrom, and thereafter washing the x-metal free phthalocyanine with a basic solution.
