John R. Cockrell, Jr. 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: 5342450
    Abstract: A method of removing from a stainless steel surface a difficultly removable soil originating from an animal or vegetable source comprising the step of contacting the soil adhered to the surface with an amount of a noncorrosive chemical composition effective to ultimately essentially chemically remove the soil from at least 51% of the surface. The difficultly removable soils that can be removed by the method of the invention are otherwise ultimately essentially chemically removable from at least 51% of the surface, at the temperature at which the above contacting step is conducted, only by contact with at least one corrosive chemical composition. The method is both safe for the user and highly effective to remove the above-described soils.
    Type: Grant

  • Patent number: 5137793
    Abstract: A food-safe composition for the pretreatment of a surface, preferably an oven or a broiler, which may be subjected to heat is liable to soiling by organic food deposits, especially baked-on food deposits.
    Type: Grant
    Filed: August 1, 1990
    Date of Patent: August 11, 1992
    Assignee: Kay Chemical Company
    Inventor: John R. Cockrell, Jr.
  • Patent number: 4877459
    Abstract: Acidic floor cleaning compositions are employed to improve the coefficient of static friction of floors, especially quarry tile, in environments conducive to the buildup of slippery-when-wet films, e.g., fast food restaurants. Such compositions, preferably buffered and containing surfactants, also improve the appearance of the floor by maintaining the floor free of ugly film without any significant attack on the grout or the tile.

  • Patent number: 4877691
    Abstract: A composition for the pre-treatment in aqueous form of a surface, preferably of an oven, which is subjected to heat and is liable to soiling by baked-on organic food deposits. A food-safe, inorganic thickening agent, in an amount sufficient so that the composition is capable of forming a continuous coating adhered to all desired portions of the preferably cleaned surface, which coating also remains continuous as the coating dries, preferably by heating, is combined with an alkaline, water-soluble inorganic salt in an amount sufficient so that the composition is readily removable with water or an aqueous solution after the composition has been dried and soiled. The composition forms a continuous film after drying. After the film becomes soiled, it can be readily removed by contact with water or an aqueous solution.

  • Patent number: 4259201
    Abstract: Granular detergent compositions containing organic peroxyacids are buffered to a pH of from about 8.5 to about 8.6 in water of about 2 grains hardness and no less than about 8 in water of about 14 grains hardness, preferably by using boric acid, to provide optimum overall cleaning.

    Assignee: The Procter & Gamble Company
    Inventors: John R. Cockrell, Jr., Dean C. Hanley
  • Patent number: 4222905
    Abstract: Laundry detergent compositions containing no or low levels of phosphate materials and specific mixtures of selected cationic surfactants, preferably having reduced cationic monomer concentrations of from about 0.005 to about 0.2, are disclosed. These compositions are unusually effective in removing particulate soils from fabrics. A process for laundering fabrics using these compositions is also disclosed.
