Hazardous or toxic waste destruction or containment April category listing, related patent applications 04/09

20090112042 - Decontamination method of metal surface contaminated by radioactive element: A decontamination gel is obtained to be spayed on a contaminated material. Places of contaminations of Co, Cs and Sr are shown by the gel. Then the gel is dried up in the air to form a film. Thus, the contaminations are cleaned by removing the film.... Agent: Troxell Law Office PLLC

20090112043 - Process and apparatus for treating a gas containing a contaminant: Apparatus, process and article for treating a gas containing one or more of a chemical and/or biological contaminant. The process includes contacting the gas with an aggregate composition comprising an insoluble rare earth-containing compound to form a gas depleted of chemical and active biological contaminants. The insoluble rare earth-containing compound... Agent: Chevron Corporation

20090112044 - Detoxification of chemical agents: This invention provides a process for the detoxification of chemical agents including chemical warfare agents such as sulfur mustards, nitrogen mustards, nerve agents of G and V type, lewisite and adamsite by reacting the chemical agents with hydroxyl radicals at a pH greater than 7.0 to detoxify the agents and... Agent: Ashok Tankha Of Counsel, Lipton, Weinberger & Husick

20090112045 - Methods and systems for asbestos treatment: A vibratory system for asbestos treatment includes a trough with a heat-resistant liner, an opening, and a discharge end. The system also includes a transportation sub-system including a frame that may be coupled to the trough, as well as a vibration generator and resilient members coupled to the frame. Further,... Agent: Marshall, Gerstein & Borun LLP

20090105516 - Method and system for neutralizing pathogens and biological organisms within a container: A system for neutralizing contaminants, such as pathogens, toxins, and biological organisms on or within an object, which may be housed in a container, such as an envelope, by focusing a plurality of energies or fields including electromagnetic, electrostatic, magnetic, or acoustic on the object in an amount effective to... Agent: Lee G. Meyer, Esq. Meyer & Associates, LLC

20090105517 - Method for chemically reducing waste material: In accordance with the present invention, a system, method and apparatus is provided for chemically reducing waste. The apparatus includes a substantially alkaline-resistant vessel having a temperature sensor positioned in thermal communication therewith, a heater in thermal communication with the vessel, a substantially alkaline-resistant magnetic stir rod adapted to be...
