Patents by Inventor Ronald Earl Highsmith

Ronald Earl Highsmith 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: 6733558
    Abstract: A beneficiated sludge solids composition comprising digested municipal sewage sludge, ammonium sulfate, and superphosphoric acid. Alternatively, a beneficiated sludge solids composition comprising digested municipal sewage sludge, ammonium sulfate, mineral acid and phosphate salt. The constituents of the beneficiated sludge solids composition of the invention act synergistically to increase economic value through increased fertilization values of nitrogen and phosphorous, decreased flammability and autocombustibility, decreased ammonia evolution on drying and decreased corrosibility. The beneficiated sludge solids composition is capable of being produced in present sewage treatment facilities.
    Type: Grant

  • Patent number: 6689181
    Abstract: Ammonium sulfate nitrate composite materials useful as fertilizers having desirable levels of nitrate ions, superior stability against detonation, higher density, greater resistance to moisture, and a method for their manufacture. The ammonium sulfate nitrate composites have as essential constituents ammonium sulfate and the NH4SO4.2(NH4NO3) double salt with less than 5 wt. % in combined total of the more hazardous NH4SO4.3(NH4NO3) double salt and ammonium nitrate.

  • Patent number: 6436164
    Abstract: An agglomeration process by which granules are formed by the steps of: (a) injecting polymer having sufficient viscoelasticity; and (b) impacting particles on the polymer at the injection point. The present invention is advantageous because it overcomes the problems of previous granulation process and subsequent art processes by having a very low recycle rate and allowing for control of granule size. It is particularly useful for fertilizer granule formation using a ureaform polymer and particles comprised of ammonium sulfate.

  • Patent number: 6423667
    Abstract: Stable concentrated suspensions readily dispersible in water comprising ammonium sulfate, a surfactant, and an oil. The ammonium sulfate particles are at least about 99 wt. % passable through a Tyler #48 sieve. The surfactant has an HLB rating from about 10 to about 15. The oil is a hydrocarbon or other non-polar oil having a viscosity of at least about 5 centipoises at 40° C. The ammonium sulfate suspensions of the invention are useful as herbicidal adjuvants, herbicidal compositions or for other purposes.
