Julia Mary Wates 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).

  • Low streak degreasing composition
    Patent number: 8980818
    Abstract: The present invention relates to an aqueous composition comprising three components. The first component is a primary detergent, non-ionic surfactant with a critical packing parameters (CPP) of ?0.95. The second component is a inorganic particle whose surface has been modified to improve stability. The third necessary component is a secondary surfactant with a CPP of ?0.85. The secondary surfactant can function to improve the overall cleaning performance, the streaking performance and provide overall formulation stability.
    Type: Grant
    Filed: December 13, 2011
    Date of Patent: March 17, 2015
    Assignee: Akzo Nobel Chemicals International B.V.
    Inventors: Julia Mary Wates, Maurice O. Dery, Alberto Slikta, Boen Ho O

  • Polybetaines as asphalt emulsifiers
    Patent number: 6540822
    Abstract: A method of emulsifying asphalt using a polyamine polybetaine, preferably a dibetaine, as an emulsifier or co-emulsifier and an emulsion of asphalt, water and a polybetaine, preferably a diamine dibetaine. The advantages of using a polyamine polybetaine as an emulsifier or co-emulsifier include its ability to provide superior cationic and anionic emulsions, and slow-setting emulsions at low use levels, and the excellent adhesion of the cured asphalt film.

  • Amine oxides as asphalt emulsifiers
    Patent number: 6494944
    Abstract: A method of emulsifying asphalt using a polyamine polyoxide, preferably a diamine dioxide, as an emulsifier or co-emulsifier and an emulsion of asphalt, water and a polyamine polyoxide, preferably a diamine dioxide. The advantages of using a polyamine polyoxide as an emulsifier or co-emulsifier include its ability to provide superior cationic and anionic emulsions, and slow-setting emulsions at low use levels, and the excellent adhesion of the cured asphalt film.
