Gayle P. Fields 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).

  • Protected metal article
    Patent number: 4790686
    Abstract: A culvert having a corrosion resistant composite coating and a method of producing the corrosion resistant composite coating. The coating method is for use in a coventional hot dip coating line of the type wherein a steel strip, having been appropriately pretreated so as to be at or above the coating temperature and have its surface free of oxides, is caused to pass through a bath of molten coating metal. A fibrous aramid paper is bonded to the surface of the steel strip by pressing the fibers into the molten coating layer immediately after the steel strip exits the coating bath. The steel strip may be fabricated into construction products such as culvert which may be further protected with bituminous type coatings.
    Type: Grant

  • Finishing method and means for conventional hot-dip coating of a ferrous base metal strip with a molten coating metal using conventional finishing rolls
    Patent number: 4444814
    Abstract: A finishing method and apparatus for use in conventional hot-dip coating of the type wherein a ferrous base metal strip, having been appropriately pretreated so as to be at or near the proper coating temperature and so as to have its surfaces free of oxides, is cause to pass beneath the surface of a bath of molten coating metal, exiting the bath between conventional finishing rolls. The method comprises the steps of providing an enclosure which overlies at least the coating metal meniscus areas created between the finishing rolls and the strip, and maintaining within the enclosure an inert or non-oxidizing atmosphere to shroud the meniscus areas. The apparatus comprises the above mentioned enclosure with an appropriate system to provide and maintain the inert or non-oxidizing atmosphere therein.
