Patents by Inventor Charles E. Leffler

Charles E. Leffler 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: 7704390
    Abstract: A wastewater treatment system for removing contaminants from wastewater on a vessel using electricity. The wastewater treatment system may inject wastewater with one or more disinfectants or ionized gases, or both, to remove at least a portion of contaminants from the wastewater. The water treatment system may produce disinfectants from saltwater using one or more disinfectant generators and return the byproducts to a water body. The wastewater treatment system may also pass wastewater through an electrical coagulation unit in which an electrical current may be emitted into the wastewater, whereby flocculants are formed and cause suspended solids and other materials to settle out of the wastewater. The wastewater treatment system may include a secondary treatment system for further reducing concentrations of contaminants. In addition, the wastewater treatment system may include a solid waste treatment system for incinerating solids produced by the wastewater treatment system.

  • Patent number: 6966996
    Abstract: A desalination system for removing at least a substantial amount of salt from a saltwater. In at least one embodiment, the desalination system may inject the saltwater with one or more ionized gases for removing contaminants from the saltwater. The desalination system may include one or more ionized gas generators for generating one or more ionized gases to be mixed with the saltwater. The desalination system may inject a disinfectant into the saltwater to disinfect the saltwater. The desalination system may generate one or more disinfectants from saltwater using a disinfectant generator. In at least one embodiment, the disinfectant generator may separate disinfectants from saltwater using electrolysis.

  • Patent number: 6923901
    Abstract: Contaminated water, particularly, ballast water, blackwater, galley water, accommodation water, laundry water, fresh water and seawater, is disinfected by admixture of a highly reactive gas stream containing ions of oxygen and nitrogen, formed by exposure of air to short-wavelength ultraviolet radiation, and of chlorine, formed in situ by electrolysis of salt in the water. Solids removal can be accomplished by electrophoresis in the same unit employed for electrolysis to release chlorine, or in a separate unit. Heavy metals maybe removed by plating or sacrificing electrodes.

  • Patent number: 5569369
    Abstract: This invention is directed to a cassette for gel electrophoresis which may be easily disassembled without disrupting or damaging the gel and which prevents the gel from sliding out of the cassette. This invention is further directed to a cassette provided with a comb carrier which allows for the easy insertion of a comb into the cassette after the gel has been poured without damaging the gel and which protects the comb from having unwanted material enter into the comb and into the gel.
