Stephen B. Ruiz 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).

  • PVC adhesives for electrodes and other applications
    Patent number: 5637642
    Abstract: This invention involved the discovery of novel polymers used as adhesives and a process for their preparation. The polymers were prepared by the nucleophilic substitution, at room temperature, of PVC with substituted alkyltrialkoxysilanes, which can be cured at room temperature to give adhesion of PVC to hydrophilic substrates. These polymers are particularly useful as adhesion promoters in ion-selective electrodes. The invention also involved the application of these adhesive primers to planar electrode substrates to give greatly improved performance in the response of ion-selective electrodes.
    Type: Grant
    Filed: May 26, 1995
    Date of Patent: June 10, 1997
    Assignee: Chiron Diagnostics Corporation
    Inventors: Mark W. Boden, Andy D. C. Chan, Susan M. Degnan, Stephen B. Ruiz
