  • Patent number: 5251398
    Abstract: The present invention relates to a method of protecting vegetation from frost or freeze by providing a coating of a composition containing partially hydrated cellulosic fibers. The coating composition optionally includes an adhesive and/or a foaming surfactant. The method is particularly useful in protecting fruit-bearing and blossoming trees from frost or freeze. The present invention also relates to a composition of cellulosic fibers for use in the protective method.
    Type: Grant

    Inventor: Leslie L. Balassa
  • Patent number: 5143780
    Abstract: The present invention relates to methods to protect curing cement or concrete from excess evaporative water loss and/or from rain, excess heat loss, or excess heat gain. More particularly the method relates to coating curing cement or concrete with a layer (or layers) of a fibrous mass composed of ground cellulose, water, a viscosity enhancing polymer, a hygroscopic swelling agent and, optionally, additives selected on the basis of the properties desired (e.g., rain resistance, heat absorption from the sun, heat reflectance, or heat insulation). The invention also relates to compositions comprising a layer of cement or concrete and a layer (or layers) of such a fibrous mass.

  • Patent number: 4822607
    Abstract: A method for treating carcinoma of the breast, carcinoma of the prostate, carcinoma of the colo-rectal area and carcinoma of the ovary having the properties of anaplasia, invasion and metastasis by administration of a granulated animal cartilage product or an aqueous extract thereof.
    Type: Grant

    Inventors: Leslie L. Balassa, John F. Prudden
  • Patent number: 4787928
    Abstract: Disclosed is a hydrated fibrous mass prepared by the steps including introducing a source of cellulosic fibers to water with continuous mixing until a ratio of water to fibers of about 50 to 1 is obtained and mixing the water and source of cellulosic fibers until the source of cellulosic fibers has been comminuted to substantially individual cellulose fibers. The mass can be effectively used as a fire controlling agent. The mass can also be used as a carrier for pesticides, and as a concrete or cement cure rate controlling agent.

  • Patent number: 4656137
    Abstract: Disclosed is a method of preparing finely divided cartilage powder from raw cartilage including the steps of mechanically trimming raw cartilage from an animal body, and granulating the raw cartilage into granules having an average size of from about 4 mm to 8 mm diameter. The granules are then subjected to azeotropic extraction, the extraction conducted with an extracting agent which both forms an azeotrope with water and solubilizes fat. The granules are then separated from the extracting agent, and milled to an average size of from about 40 to 70.mu. diameter.Also disclosed is a method of separating calcium compounds from cartilage including the steps of mechanically trimming raw cartilage from an animal body, granulating the raw cartilage into granules having an average size of from about 4 to 8 mm diameter, and partially drying the granules to produce a friable calcified outer layer on each granule.

    Inventor: Leslie L. Balassa
  • Patent number: 4350682
    Abstract: A biologically active cartilage product is prepared by heating a mixture of crude animal or fish cartilage in water under pressure to form an aqueous cartilage extract, removing suspended matter from the extract and concentrating the extract under vacuum. The product may be dried to form a fine granular material.
