  • Patent number: 6434884
    Abstract: A biostimulating substance, useful in agriculture, horticulture and microbial processes, is composed of acetic acid and a fossil humic substance containing solid humins and humic acid. A method for improving the biostimulating properties and stability of dispersions of fossil humic substances containing peat or lignite includes the step of mixing a fossil humic substance with acetic acid in an amount sufficient that the resulting suspension contains at least about 5 to about 25% by weight organic solids. The modified humic substance can be used as a biostimulant for enhancing plant growth and health and for increasing digestion of organic solids by microorganisms in sewage plants and similar facilities.

  • Patent number: 6406282
    Abstract: A sealing ring and rim assembly for use with an outer curing envelope to retread a tire casing. The assembly includes a rigid annular rim having a fixed diameter and a resiliently expandable elastomeric annular sealing rim captured on the rim. An inflatable bladder is located between the rim and the sealing ring so that, when the bladder is inflated, the sealing ring expands into uniform sealing engagement with an inner peripheral bead of the tire casing. The use of an inflatable bladder ensures that sealing pressure will be uniformly exerted so that an endless band of seal is created about the entire circumference of the tire bead. In addition, one particular size of the assembly is capable of use on a variety of tires having a tire bead circumference within a range of circumferences.

  • Patent number: 6393803
    Abstract: A process for blow-molding and coating plastic containers under conditions of positive control in a close-coupled, compact machine to enhance operational efficiency. According to one of the preferred methods, the containers are coated promptly after the containers are discharged from hot molds to take advantage of the residual heat of the freshly blown containers to enhance curing/drying of the coating and to enhance bonding of the coating to the container surface. According to another one of the preferred methods, the containers are aseptically filled and capped either before or after the containers are coated. Alternatively, the process can include hot-filling and capping of containers in which the containers are coated promptly after being hot-filled to take advantage of the elevated temperature of the hot-filled containers.
