Patent number: 7763219Abstract: An apparatus and method for processing hazardous wastes directly from 55-gallon drums through the use of pyrolysis and steam reforming. The method is based on a pyrolyzer using heat to vaporize organics that are present in the hazardous wastes. The waste is heated in the original drums to avoid the bulk handling of alpha radionuclides and to ensure criticality control. At pyrolysis temperatures, all liquids and organics in the drums will evaporate and volatize. The resulting waste in the drums is a dry, inert, inorganic matrix with carbon char containing radioactive metals. The off-gas produced by pyrolysis mainly consists of water vapor, volatized organics, and acid gases from the decomposition of various plastics and other organics present in the waste drums. The off-gas produced by the pyrolysis is then collected and fed into an off-gas treatment system that is in fluid communication with pyrolyzer operated under oxidizing conditions.Type: GrantFiled: March 14, 2007Date of Patent: July 27, 2010Assignee: Studsvik, Inc.Inventor: J. Bradley Mason

Patent number: 7531152Abstract: A system and method for conversion of alkali metals, heavy metals, halogens, and sulfur into mineral products. The system includes a single reaction vessel. To begin the process, co-reactants such as lime and clay are mixed with waste feeds containing alkali metals, heavy metals, halogens, and sulfur. This mixture is then introduced into the reaction vessel. The reaction vessel is operated under reducing conditions. After the mineral products are allowed to form, they are collected from the reaction vessel.Type: GrantFiled: February 26, 2003Date of Patent: May 12, 2009Assignee: Studsvik, Inc.Inventor: J.

Patent number: 7476194Abstract: A method of waste stabilization by mineralization of waste material in situ in a treatment container suitable or treatment, transit, storage and disposal. The waste material may be mixed with mineralizing additives and, optionally, reducing additives, in the treatment container or in a separate mixing vessel. The mixture is then subjected to heat in the treatment container to heat-activate mineralization of the mixture and form a stable, mineralized, monolithic solid. This stabilized mass may then be transported in the same treatment container for storage and disposal.Type: GrantFiled: October 22, 2004Date of Patent: January 13, 2009Assignee: Studsvik, Inc.Inventors: John Bradley Mason, Thomas W.

Publication number: 20080181835Abstract: A system for the treatment and recycling of graphite containing radionuclides including a two stage method that employes a thermal roaster that is operatively connected to a steam reformer. In the first stage, radioactive graphite is roasted or heated to volatize a first amount of radionuclides contained in the graphite. In the second stage, the roasted graphite is reacted with steam or gases containing water vapor so that a second amount of radionuclides is removed. Optionally, the present system also processes the radionuclides to enable their disposal.Type: ApplicationFiled: November 9, 2007Publication date: July 31, 2008Inventor: J. Bradley Mason

Publication number: 20070244419Abstract: A hinge assembly for a knee brace includes a screw seat, a screw seat gear, an adjustment screw, a condyle engagement member, and an adjustment actuator gear. The screw seat has a bore with an internal thread. The screw seat gear is positioned at an end of the screw seat and the screw seat rotates in response to rotation of the screw seat gear. The adjustment actuator gear engages the screw seat gear and the screw seat gear rotates in response to rotation of the adjustment actuator gear. The adjustment screw has an external thread that is threaded into the internal thread of the screw seat, thereby enabling outward or inward telescoping of the adjustment screw within the bore in response to rotation of the adjustment actuator gear.Type: ApplicationFiled: April 13, 2006Publication date: October 18, 2007Inventors: Bradley Mason, Aadel Al-Jadda

Publication number: 20070118194Abstract: A therapy system for therapeutically treating a desired region of the body includes a fluid reservoir, a heat transfer pad, and first and second fluid circulation lines. The heat transfer pad includes a first pad port, a bladder, and a second pad port. The first fluid circulation line is connectable to the first pad port for withdrawing heat transfer fluid from the fluid reservoir and delivering it to the heat transfer pad. The second fluid circulation line is connectable to the second pad port for withdrawing heat transfer fluid from the heat transfer pad and delivering it to the fluid reservoir. The heat transfer pad additionally includes a pad flowpath adjustment member positioned in the pad flowpath to adjust the system resistance to flow. The adjusted system resistance to flow fixes the desired treatment temperature of the heat transfer pad in response to the heat transfer fluid circulating through the pad flowpath. The desired treatment temperature is correlated to the body region being treated.Type: ApplicationFiled: November 22, 2005Publication date: May 24, 2007Inventors: Bradley Mason, Jeffrey Mason

Patent number: 7125531Abstract: A system and method is described having a single reaction vessel (12) using superheated stream optionally augmented by oxygen for reducing nitrogen oxides present in a wide variety of organic compounds. Reduction takes place quickly when a stream/oxygen mixture is injected into a fluidized bed (22) of ceramic beads. Reducing additives are metered into the reaction vessel (12) and/or provide energy input to reduce nitrates to nitrogen. The speed of the fluidizing gas mixture agitates the beads that then help to break up solid wastes and to allow self-cleaning through abrasion thereby eliminating agglomerates, and the oxygen, when used, allows for some oxidation of waste by-products and provides an additional offset for thermal requirements of operation.Type: GrantFiled: October 19, 2000Date of Patent: October 24, 2006Assignee: Studsvik, Inc.Inventor: J. Bradley Mason
