Patents by Inventor Jay M. Henis

Jay M. Henis 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).

  • Modified polymeric surfaces and process for preparing same
    Patent number: 5139881
    Abstract: A process for surface modifying a variety of polymeric support surfaces is disclosed in which a predetermined modifying polymer is irreversibly absorbed onto essentially all the surfaces of the support polymer accessible to the modifying polymer. The modifying polymer is selected to impart the desired surface characteristics to the modified polymeric surface.
    Type: Grant
    Filed: November 17, 1988
    Date of Patent: August 18, 1992
    Assignee: Monsanto Company
    Inventors: Jay M. Henis, Mary K. Tripodi, Donald I. Stimpson
  • Encapsulation of biological material in non-ionic polymer beads
    Patent number: 5089407
    Abstract: Biological materials such as enzymes, proteins and peptides are encapsulated by forming a mixture of the material and an aqueous non-ionic polymer solution, spraying the mixture into a circulating water-immiscible nonsolvent for the polymer at a temperature sufficient to freeze the beads and drying the frozen beads to remove essentially all unbound water such as to provide a water content of about 1-2 weight percent. Suitable non-ionic polymers are poly(vinyl alcohol), polyvinylpyrollidone, dextran and derivatized cellulose. A densification agent such as alumina may be present in the polymer solution to enhance specific gravity of the beads formed. Encapsulated material such as microbes produced by this process provide useful agricultural agents which can be delivered to the market in a dormant state and suitable for delivery to soil or plant leaves. The beads can be applied dry, via a planting or an insecticide box, or wet via a spray nozzle.

  • Process for removing sulfur dioxide and nitrogen oxides from gases
    Patent number: 4011299
    Abstract: Process for removing sulfur dioxide and nitrogen oxides from gaseous mixtures which comprises contacting such mixtures, in the presence of a reducing agent comprising carbon monoxide, hydrogen, or mixtures thereof, with a solid reagent comprising calcium oxide, magnesium oxide, or mixtures thereof at temperatures in excess of about 700.degree. C.
