Patents by Inventor Thomas E. Foye

Thomas E. Foye has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Pigment product
    Patent number: 4910236
    Abstract: An ink is produced without flushing by forming both an emulsion of a selected organic liquid and water and an aqueous suspension of a pigment. The emulsion and the pigment are then mixed together, whereby the pigment is phase-transferred from the aqueous phase to the non-aqueous phase, and whereby a mixture is formed. The mixture is concentrated (e.g. via filtration) and added to an ink mixing tank where the remaining water is removed by evaporation and wherein the remaining ingredients are added so that the ink is produced.
    Type: Grant
    Filed: January 19, 1988
    Date of Patent: March 20, 1990
    Assignee: BASF Corporation
    Inventors: Thomas E. Foye, Edward K. Sasamoto, Reinhard J. Sappok
  • Low viscosity, highly concentrated pigment dispersions and method of making same
    Patent number: 4859247
    Abstract: An oil-soluble viscosity-reducing additive made by combining an amine and a polybasic organic acid permits the incorporation of large proportions of pigment into pigment dispersions. The increased proportion of pigment provides advantages in the manfacture of inks.
    Type: Grant
    Filed: November 2, 1987
    Date of Patent: August 22, 1989
    Assignee: BASF Corporation
    Inventors: Thomas E. Foye, Joseph P. Baillargeon
  • Lithographic ink composition and process for making same
    Patent number: 4822419
    Abstract: A lithographic ink has an oil-soluble additive incorporated thereinto, the additive producing beneficial effects, especially with respect to reducing the pH drift of the ink during use. The additive is produced by combining a primary, secondary, tertiary, or quaternary amine with a polybasic organic acid.

    Assignee: BASF Corporation
    Inventors: Thomas E. Foye, Edward K. Sasamoto
  • Pigment flushing
    Patent number: 4340431
    Abstract: A method for transferring an organic pigment from an aqueous pulp of the pigment to a water-immiscible organic vehicle. This method comprising mixing the aqueous pulp and vehicle with a petroleum sulfonate flushing aid and at least one flushing aid selected from the class consisting of sulfonated sperm oil, sulfated sperm oil, and mixtures thereof until a major portion of the water present in said pulp separates.
    Type: Grant
    Filed: November 10, 1980
    Date of Patent: July 20, 1982
    Assignee: BASF Wyandotte Corporation
    Inventors: Manohar L. Arora, Timothy A. Overway, Thomas E. Foye
  • Pigment flushing
    Patent number: 4309320
    Abstract: In the method for transferring an organic pigment from an aqueous pulp to a water-immiscible hydrophobic organic vehicle the improvement to achieve low initial viscosity, good shelf stability, and good tint strength comprising incorporating an additive selected from the class of sulfonated sperm oil, sulfated sperm oil and mixtures thereof with said vehicle and said pigment.
