Publication number: 20240173891Abstract: A method of plugging channels of a honeycomb body and a honeycomb body including plugged channels. The method includes applying a shear force to a plugging mixture including a plurality of inorganic particles, clay, and a liquid vehicle to alter the viscosity of the plugging mixture from a first viscosity prior to the vibrating to a second viscosity which is less than the first viscosity. A honeycomb body is placed into contact with the plugging mixture such that a portion of the plugging mixture having the second viscosity flows into the plurality of channels. Application of the shear force is stopped or reduced to increase the viscosity of the portion of the plugging mixture in the plurality of channels to greater than the first viscosity.Type: ApplicationFiled: January 31, 2024Publication date: May 30, 2024Inventors: Keith Norman Bubb, Theresa Chang, Joseph Henry Citriniti, Kevin Eugene Elliott, Xinyuan Liu, Robert John Locker, Prashanth Abraham Vanniamparambil, Kevin Lee Wasson, Shu Yuan

Publication number: 20100146654Abstract: A method of reconstituting an animal embryo involves transferring a diploid nucleus into an oocyte which is arrested in the metaphase of the second meiotic division. The oocyte is not activated at the time of transfer, so that the donor nucleus is kept exposed to the recipient cytoplasm for a period of time. The diploid nucleus can be donated by a cell in either the GO or G1 phase of the cell cycle at the time of transfer. Subsequently, the reconstituted embryo is activated. Correct ploidy is maintained during activation, for example, by incubating the reconstituted embryo in the presence of a microtubule inhibitor such as nocodazole. The reconstituted embryo may then give rise to one or more live animal births. The invention is useful in the production of transgenic animals as well as non-transgenics of high genetic merit.Type: ApplicationFiled: December 24, 2009Publication date: June 10, 2010Inventors: Keith Henry Stockman Campbell, Ian Wilmut

Patent number: 7514258Abstract: A method of reconstituting an animal embryo involves transferring the nucleus from a quiescent donor cell into a suitable recipient cell. The donor cell is quiescent, in that it is caused to exit from the growth and division cycle at G1 and to arrest in the G0 state. Nuclear transfer may take place by cell fusion. The reconstituted embryo may then give rise to one or more animals. The invention is useful in the production of transgenic animals as well as non-transgenics of high genetic merit.Type: GrantFiled: November 3, 2005Date of Patent: April 7, 2009Assignee: Roslin Institute (Edinburgh)Inventors: Keith Henry Stockman Campbell, Ian Wilmut

Patent number: 7439039Abstract: The serotonin transporter (SERT) is a target of various therapeutic agents used in the treatment of neurological and neurodegenerative disorders. The present invention provides novel forms of SERT that lacks high affinity recognition of specific serotonin reuptake inhibitors (SSRIs). The present invention therefore provides a novel target for use in screening and model development that can aid both the discovery of new medications and the discovery of novel pathways impacted in parallel with SERT blockade. Such novel targets can help identify new SSRI's with unique modifications and lead to discovery of pathways that secondarily support the therapeutic activity of these agents.Type: GrantFiled: July 2, 2004Date of Patent: October 21, 2008Assignee: Vanderbilt UniversityInventors: Randy D. Blakely, Loren Keith Henry, Erika M. Adkins

Patent number: 7378761Abstract: A control circuit (1) includes two input terminals (2, 3) for respectively electrically connecting with the active and neutral conductors (4, 5) of a mains power source (6). Two output terminals (7, 8) electrically connect with a load in the form of a two pin domestic electrical appliance (9). Conductors (4, 5) terminate at a domestic power outlet socket, and terminals (7, 8) are incorporated into a two pin plug for insertion into that socket. That is, terminals (7, 8) include elongate bundled conductors for extending between the outlet socket and the circuit. Appliance (9) has a conductive component, in this instance a housing (10) that, under normal operating conditions, is electrically insulated or otherwise electrically isolated from conductors (4, 5). The housing provides a reference point for circuit (1), and is electrically connected to that circuit by way of a conductor (11).Type: GrantFiled: August 4, 2003Date of Patent: May 27, 2008Assignee: Protectelec Pty LtdInventors: Wayne Callen, Richard Leslie Brissenden, Robert Keith Henry Smith

Patent number: 7354507Abstract: The present invention is generally related towards enhancing the yield and/or cold-flow properties of certain hydrocarbon products, increasing the degree of isomerization in a diesel product and/or increasing the production rate of a diesel product. The embodiments generally include reducing the residence time of lighter hydrocarbon fractions during hydrocracking, thereby decreasing secondary cracking, by various configurations of introducing at least two hydrocarbon feedstreams of different boiling ranges at different entry points in a hydrocracking unit. A method further includes forming a hydrocarbons stream comprising primarily C5+ Fischer-Tropsch hydrocarbon products; fractionating hydrocarbons stream to form at least a wax fraction and an intermediate fraction which serve as separate feedstreams to a hydrocracking unit comprising at least two hydroconversion zones.Type: GrantFiled: March 17, 2004Date of Patent: April 8, 2008Assignee: ConocoPhillips CompanyInventors: Sridhar Gopalakrishnan, Vincent H.
