Patents by Inventor Bobby R. Skipper

Bobby R. Skipper 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).

  • Patent number: 5573658
    Abstract: A low brightness pigment and method is provided from a heretofore rejected waste kaolin stream. Kaolin processing rejects are high in iron-stained TiO.sub.2. After separating the stained TiO.sub.2 from the high brightness kaolin and concentrating the resulting fraction, the material can be processed to produce a low brightness pigment suitable of many applications where lower brightness is desirable, such as coating paper board without mottling.
    Type: Grant
    Filed: December 28, 1994
    Date of Patent: November 12, 1996
    Assignee: J. M. Huber Corporation
    Inventors: Albert C. Kunkle, Robert E. Hardy, Bobby R. Skipper

  • Patent number: 4088732
    Abstract: A method of beneficiating kaolin clay by the addition of non-dispersing neutral salts to assist in the removal of discolored impurities, such as titanium and iron bearing minerals from a clay slurry. This process is capable of producing clays having a brightness in the 90- 95 range.
