  • Self contained air flow and ionization method, apparatus and design for internal combustion engines
    Patent number: 6601570
    Abstract: This invention method combines numerous disciplines to enhance the performance of internal combustion engines. No prior art embodies the discipline of physics in the creation of a swirling vortex, principles of electrostatics in using tribology and coulomb forces, the utilization of dielectric properties of polymers in an air driven rotating electrophorus and the chemistry of enhanced combustion gases and combustion itself in a single self-contained apparatus and does so without the convention and application of external voltage.

  • Method of collecting response data from direct mail advertising
    Patent number: 4752675
    Abstract: A method for determining the effectiveness of a mass advertising wherein each advertising material sent to a particular addressee is encoded before sending with its unique identifying bar code bymbol. The material invites each addressee to return to the sender at least the portion of the material containing the symbol. The returned symbols are read and the information encoded in the symbol is transmitted to a computer containing a master file list of the respective symbols associated with the corresponding addressees. The information from the returned symbols is compared with the master file list for analysis of the effectiveness of the advertising.
