Patent number: 7138046Abstract: A process for the production of hydrogen from anaerobically decomposed organic materials by applying an electric potential to the anaerobically decomposed organic materials, including landfill materials and sewage, to form hydrogen, and for decreasing the time required to treat these anaerobically decomposed organic materials. The organic materials decompose to volatile acids such as acetic acid, which may be hydrolyzed by electric current to form hydrogen. The process may be continuously run in sewage digestion tanks with the continuous feed of sewage, at landfill sites, or at any site having a supply of anaerobically decomposed or decomposable organic materials.Type: GrantFiled: August 17, 2001Date of Patent: November 21, 2006Assignee: World Hydrogen Energy LLCInventor: Sukomal Roychowdhury

Publication number: 20040232007Abstract: A mediated electrochemical oxidation process is used to treat, oxidize and destroy food waste materials, such as manure, biological residue, hay, straw, animal byproducts, bones, horns, blood, biological items, pathological waste and combined waste. Food waste is introduced into an apparatus for contacting the waste with an electrolyte containing the oxidized form of one or more reversible redox couples, at least one of which is produced by anodic oxidation in an electrochemical cell. The oxidized species of the redox couples oxidize the organic waste molecules and are themselves converted to their reduced form, whereupon they are reoxidized by either of the aforementioned mechanisms and the redox cycle continues until all oxidizable waste species, including intermediate reaction products, have undergone the desired degree of oxidation. The process takes place at temperatures between zero degrees centigrade and below the boiling point of the electrolyte.Type: ApplicationFiled: April 8, 2004Publication date: November 25, 2004Inventors: Roger W Carson, Bruce W Bremer

Publication number: 20030226766Abstract: A variety of pollutants and other contaminants may be removed from a variety of aqueous media using electrolytic treatments. The treatment includes inserting an anode and a cathode into the medium undergoing treatment, and applying a high current and voltage to the electrodes. The treatment may also include the addition of catalytic enzymes to the medium undergoing treatment. The present methods are compatible with aquatic lifeforms, and offer an effective alternative to chemical-based water treatment systems.Type: ApplicationFiled: June 5, 2002Publication date: December 11, 2003Inventor: David N. Orlebeke

Patent number: 6306275Abstract: A process for controlling the micelle size distribution of an alkylene oxide dispersion in a nickel-plating electrolyte is used to maintain the electrolyte in a condition suitable for producing nickel coatings having a uniform satin finish in which finish characteristics such as roughness depth are maintained within desired limits. The process involves steps of removing a portion of the electrolyte from the electroplating bath, filtering the alkylene oxide from the electrolyte removed from the electroplating bath, adding alkylene oxide to the electroplating bath, and returning the filtered electrolyte to the electroplating bath. The process removes larger alkylene oxide micelles from the electrolyte and replaces them with smaller micelles to maintain a desired micelle size distribution.Type: GrantFiled: March 31, 2000Date of Patent: October 23, 2001Assignee: Lacks Enterprises, Inc.Inventors: Lawrence P. Donovan, III, Roger J. Timmer, David P. Hartrick

Patent number: 5810996Abstract: Electro-osmotic (or electrokinetic) transport is used to efficiently force a solution (or water) through the interior of the fibers or yarns of textile materials for wet processing of textiles. The textile material is passed between electrodes that apply an electric field across the fabric. Used alone or in parallel with conventional hydraulic washing (forced convection), electro-osmotic transport greatly reduces the amount of water used in wet processing. The amount of water required to achieve a fixed level of rinsing of tint can be reduced, for example, to 1-5 lbs water per pound of fabric from an industry benchmark of 20 lbs water/lb fabric.Type: GrantFiled: January 17, 1996Date of Patent: September 22, 1998Assignee: The Regents of The University of CaliforniaInventor: John F.

Patent number: 5667667Abstract: A method of electrochemically patterning a surface comprises providing an electrolyte overlying the surface and an array of electrodes adjacent the surface and in contact with the electrolyte, and altering the potential of one or more electrodes of the array so as to deposit or remove or chemically modify a substance on the surface adjacent the electrode. Several such treatments can be performed in sequence, using different electrodes of the array. The method is particularly suitable for step-wise chemical synthesis e.g. of oligonucleotides or other oligomers tethered to the surface. Electrode arrays for use in the method are also claimed.Type: GrantFiled: July 18, 1996Date of Patent: September 16, 1997Assignee: Isis Innovation LimitedInventor: Edwin Southern

Patent number: 5667668Abstract: Pulping chemicals and hemicellulose are recovered from a starting solution essentially free of lignin but containing a mixture of hemicellulose and caustic by electrolyzing this solution in the anolyte compartment of an electrolytic cell. By electrolysis, the concentration of caustic in the anolyte is decreased and the concentration of caustic in a catholyte of said cell is increased so as to allow recovery of about 60 to about 80 percent of the caustic present in the hemicellulose caustic starting solution.Type: GrantFiled: July 12, 1996Date of Patent: September 16, 1997Assignee: Huron Tech CorpInventors: Stephen W.
