Patent number: 10336635Abstract: A subsurface sewage disposal system includes leaching members oriented substantially vertically and positioned in a non-linear arrangement. A first volume is defined within the leaching members by a permeable enclosure configured to provide temporary storage of an effluent introduced by a distribution pipe. A plurality of balancing pipes is configured in a non-linear arrangement to redistribute the effluent from one leaching member to another leaching member. As the effluent rises within one leaching member, the effluent is redistributed by the balancing pipes to another leaching member. In the event of a failure of the distribution pipe, the plurality of balancing pipes is configured to bypass the distribution pipe and redistribute the effluent to the leaching members downstream of such failure.Type: GrantFiled: December 15, 2017Date of Patent: July 2, 2019Inventor: Richard Couch

Patent number: 9850150Abstract: A subsurface sewage is provided and includes a plurality of leaching members oriented substantially vertically. A first volume defined within each of the plurality of the leaching members forms a void therein and includes a periphery, a top face that defines a first substantially horizontal plane, and a bottom face that defines a second substantially horizontal plane. A permeable enclosure is wrapped substantially around the periphery of each leaching member and a system frame maintains a location and a position of the plurality of the leaching members. A filter media is disposed in a second volume defined between at least two of the plurality of the leaching members. A leaching member balancing pipe is configured to hydraulically connect at least one of the plurality of the leaching members to at least one other of the plurality of the leaching members. A distribution pipe is configured to hydraulically connect at least one of the plurality of the leaching members to a source of an effluent flow.Type: GrantFiled: October 4, 2013Date of Patent: December 26, 2017Inventor: Richard Couch

Patent number: 9144551Abstract: Drug formulations having reduced abuse potential which contain one or more of (1) a bittering agent, (2) a bright deterrent/indicator dye and (3) fine insoluble particulate matter. The bittering agent and dye are in a form which does not affect proper administration of the drug, but the bittering agent creates a bitter side effect when the dosage form is crushed or chemically extracted and nasally, orally, buccally or sublingually administered and the dye produces a bright color when crushed and contacted. The fine insoluble particulate matter hinders extraction of the drug from the dosage form and, when crushed, can deter intravenous injection because of the presence of the insoluble particles or hinder injection by blocking an intravenous needle. The bright color of the dye, when extracted, also has a psychologically deterrent effect on intravenous abusers.Type: GrantFiled: December 8, 2014Date of Patent: September 29, 2015Assignee: Supernus Pharmaceuticals, Inc.Inventors: Rong-Kun Chang, Richard A. Couch, Beth A. Burnside

Publication number: 20060289407Abstract: A plasma arc torch that includes a torch body having a nozzle mounted relative to a composite electrode in the body to define a plasma chamber. The torch body includes a plasma flow path for directing a plasma gas to the plasma chamber in which a plasma arc is formed. The nozzle includes a hollow, body portion and a substantially solid, head portion defining an exit orifice. The composite electrode can be made of a metallic material (e.g., silver) with high thermal conductivity in the forward portion electrode body adjacent the emitting surface, and the aft portion of the electrode body is made of a second low cost, metallic material with good thermal and electrical conductivity. This composite electrode configuration produces an electrode with reduced electrode wear or pitting comparable to a silver electrode, for a price comparable to that of a copper electrode.Type: ApplicationFiled: July 28, 2006Publication date: December 28, 2006Inventors: David Cook, Kirk Ferland, Charles Hackett, Yong Yang, Richard Couch, Zhipeng Lu
