Publication number: 20090071510Abstract: The present invention is directed to a method and system of processing and removing hydrocarbon sludge from a tank wherein the hydrocarbon sludges are the product of gravity settling in the bottom of the tank to form a sludge consisting of inorganic and organic materials not readily flowable or pumpable for removal in the found state and where a process is used to selectively separate, grind, disperse and suspend these materials with a mechanical classifier system, and where flow agents may be metered to effect a slurry stream directed thru a nozzle system towards the sludge in the tank and by reducing the surface tension and mechanical conditioning of the sludge, create a pumpable slurry that may be removed from the tank with minimal time, cost and environmental impact.Type: ApplicationFiled: November 19, 2008Publication date: March 19, 2009Applicant: JR & JH HOLDINGS, LLCInventor: John C. Hancock

Publication number: 20090072057Abstract: The invention relates to a method for the comminuting of natural or synthetic mineral products having a size of 10 nm to 30 mm, which are obtained from the upstream process in pre-comminuted form for example in a roller mill for inter-particle comminution, wherein these solids are further comminuted in a working process initially dry then wetted with liquid and in this liquid are comminuted so as to obtain a suspension that can be pumped, which suspension is subsequently ground to the desired final fineness by means of agitating mills.Type: ApplicationFiled: September 16, 2008Publication date: March 19, 2009Inventor: Udo Enderle

Patent number: 7497392Abstract: A process to transform solid waste into fuel by adding water and heat to provide no more than 350 BTUs/lb of the weight of the solid waste for no more than 85 minutes. Such a process transforms the solid waste into fuel in a process time of not greater than 85 minutes. The system uses a pressure vessel; a condenser tank to permit selective addition of water to and evacuation of steam from the vessel; a heater to increase the temperature of the vessel; a vacuum pump to selectively reduce pressure within the vessel and to help evacuate steam from the vessel to the condenser tank; and a water pump to selectively add water from the condenser tank to the interior volume of the vessel. A method for converting solid waste into fuel includes loading the solid waste into a rotating pressure vessel and transforming the solid waste into fuel by adding water; reducing pressure; adding heat; and then evacuating steam. The contents are evacuated from the pressure vessel. At least some of the contents are fuel.Type: GrantFiled: July 17, 2006Date of Patent: March 3, 2009Assignee: Alliance Technology Group, Inc.Inventors: Olaf Nathan Lee, Gregory Michael Fuchs

Patent number: 7484679Abstract: A method of milling cerium compound by means of a ball mill using a milling medium, characterized in that ratio Hb/r of radius r of a cylindrical ball mill container and depth Hb of the milling medium in the ball mill container disposed horizontally ranges from 1.2 to 1.9, and the ball mill container is rotated at a rotational speed which is 50% or less of critical rotational speed Nc=299/r1/2 of the ball mill container converted from the radius r expressed in centimeter. The milling method can be carried out in a wet or dry process, and the cerium compound is preferably cerium oxide. The method can be also applied for producing a cerium compound slurry.Type: GrantFiled: July 3, 2003Date of Patent: February 3, 2009Assignee: Nissan Chemical Industries, Ltd.Inventors: Isao Ota, Kenji Tanimoto, Gen Yamada, Noriyuki Takakuma

Patent number: 7481385Abstract: A process is described for treating waste organic material such as the by-products from a pulp and paper mill, manure and straw to reduce its moisture content to a level at which the treated material is suitable for use as a fuel. The process involves the steps of feeding the starting material into a chamber (10) having rotating chains (42) or blades which drive the material into the interior wall (18) of the chamber (10) with sufficient force to cause some of its moisture content to separate from it. The moisture is expelled from the chamber (10) while the remaining material is carried upwardly in a stream of air to a cyclone separator (22). The conditions within the separator (22) are adjusted to further reduce its moisture level to about 15 percent by weight at which level the material is suitable for use as a fuel.Type: GrantFiled: January 14, 2004Date of Patent: January 27, 2009Assignee: First American Scientific Corp.Inventors: Sundar Narayan, Calvin Leslie Kantonen

Patent number: 7451943Abstract: A method of preparation of a liquid electrostatographic toner or liquid ink jet ink which includes the steps of heating a marking particle mix of particles of a resin and a colourant blend in a carrier liquid to a temperature between about the first softening point of the resin and about the second softening point of the resin, maintaining the temperature of the heated marking particle mix for a selected period of time, cooling the marking particle mix to room temperature, and mixing the marking particle mix with high shear. The particle mix can be produced by coarse grinding in a ball mill. The resultant toner or ink has an improved Newtonian like flow behaviour, improved electrical properties, reduced sedimentation and agglomeration and significantly improved optical density and reduced background. The invention also includes toners and inks produced by the method.Type: GrantFiled: September 14, 2004Date of Patent: November 18, 2008Assignee: Research Laboratories of Australia Pty Ltd.Inventor: Herbert Lee Marko
