  • Publication number: 20020155241
    Abstract: Feeding tubes are provided having at least an inner surface that is coated with an amount of a source of a hydrophilic functional group effective to reduce protein adsorption and/or subsequent clogging of the feeding tube. In other forms of the invention, feeding tubes having inner surfaces that are provided with the hydrophilic functional group are also described. Methods for reducing protein adsorption to a surface of a feeding tube are also provided.
    Type: Application

  • Patent number: 5545803
    Abstract: The present invention includes a method of treating solid earthen material having volatile, semi-volatile, and non-volatile contaminants that utilizes electrical energy. A plurality of electrodes are inserted into a region of earthen material to be treated in a selected geometric pattern. Varying phase and voltages configurations are applied to corresponding electrodes to achieve heating, physical phase changes, and the placement of substances within the treatment region. Additionally, treatment mediums can be added to either treat the contamination within the soil or to restrict their mobility.

  • Patent number: 5330291
    Abstract: The present invention includes a method of treating solid earthen material having volatile, semi-volatile, and non-volatile contaminants. Six electrodes are inserted into a region of earthen material to be treated in a substantially equilateral hexagonal arrangement. Six phases of voltages are applied to corresponding electrodes. The voltages are adjusted within a first range of voltages to create multiple current paths between pairs of the electrodes. The current paths are evenly distributed throughout the region defined by the electrodes and therefore uniformly heat the region. The region of earthen material is heated to a temperature sufficient to substantially remove volatile and semi-volatile contaminants by promoting microbial action. This temperature is less than a melting temperature of the earthen material.
