HONEYCOMB STRUCTURE COMPRISING A CEMENT SKIN COMPOSITION WITH CRYSTALLINE INORGANIC FIBROUS MATERIAL
Publication number: 20170044066Abstract: Disclosed is a honeycomb support structure comprising a honeycomb body and an outer layer or skin formed of a cement that includes an inorganic filler material having a first coefficient of thermal expansion from 25 C to 600 C and a crystalline inorganic fibrous material having a second coefficient of thermal expansion from 25 C to 600 C. Skin cement composition controls level of cement liquid/colloid components, for example water, colloidal silica, and methylcellulose migration into the substrate during the skin application process to form barrier to skin wetting and staining during the washcoating process.Type: ApplicationFiled: May 1, 2015Publication date: February 16, 2017Inventors: Keith Norman Bubb, Thomas Richard Chapman, Kenneth Joseph Drury, Christopher Lane Kerr, Mark Alan Lewis, Robert John Locker, Huthavahana Kuchibhotla Sarma, Todd Parrish St Clair -
Publication number: 20160313424Abstract: Described here are systems and methods for obtaining measurements of both tissue perfusion and permeability with a magnetic resonance imaging (“MRI”) system after the administration of a single dose of contrast agent. To this end, the MRI system is directed to acquire T2*-weighted data, during which the acquired signal values are monitored for a trigger event. When the trigger event occurs, the MRI system is directed to switch from acquiring the T2*-weighted data to acquiring T1-weighted data. The systems and methods of the present invention can thus be used for a fully automated, single acquisition of perfusion and permeability measurements using only a single dose of contrast agent.Type: ApplicationFiled: December 2, 2013Publication date: October 27, 2016Inventor: Todd Parrish

Patent number: 9444026Abstract: Doped and partially-reduced oxide (e.g., SrTiO3-based) thermoelectric materials. The thermoelectric materials can be single-doped or multi-doped (e.g., co-doped) and display a thermoelectric figure of merit (ZT) of 0.2 or higher at 1050 K. Methods of forming the thermoelectric materials involve combining and reacting suitable raw materials and heating them in a graphite environment to at least partially reduce the resulting oxide. Optionally, a reducing agent such as lanthanum boride, titanium carbide, titanium nitride, or titanium boride can be incorporated into the starting materials prior to the reducing step in graphite. The reaction product can be sintered to form a dense thermoelectric material.Type: GrantFiled: April 14, 2014Date of Patent: September 13, 2016Assignee: CORNING INCORPORATEDInventors: Monika Backhaus-Ricoult, Lisa Anne Moore, Charlene Marie Smith, Todd Parrish St Clair

Publication number: 20160090329Abstract: A method and apparatus to treat a dried unfired article comprising a ceramic precursor composition substantially held together by a binder, to be resistant to binder soluble solvent based processing. The method includes depositing a fluid on the article surface, and polymerizing the deposited fluid to form a polymer thin layer on the surface. The fluid may be an aerosol, a vapor, a fog, a mist, a smoke, or combinations thereof. An apparatus to perform the method and an article resistant to binder soluble solvent based processing are also provided. The article can be an unfired honeycomb body that includes a dried composition of ceramic precursor substantially held together by a binder and a layer disposed on a surface of the unfired honeycomb body. The surface to be exposed in the green state to a binder soluble solvent and the layer protects the binder from solubilization by the solvent.Type: ApplicationFiled: December 10, 2015Publication date: March 31, 2016Inventors: Kenneth Joseph Drury, Paul John Shustack, Todd Parrish St. Clair

Publication number: 20140327186Abstract: Systems and methods for rapid drying of ceramic greenwares having a high graphite content are disclosed. The methods include employing microwave drying to bring the dryness of the ceramic greenware to a first select dryness and then employing close-coupled hot-air drying to bring the dryness to the final target dryness. The judicious use of close-coupled hot-air drying reduces end defects due to unevenness in the microwave drying process while also substantially speeding up the drying process. Various configurations for and combinations of microwave drying and close-coupled hot-air drying are disclosed.Type: ApplicationFiled: March 31, 2014Publication date: November 6, 2014Applicant: Corning IncorporatedInventors: Willard Ashton Cutler, James Anthony Feldman, Jacob George, Amit Halder, Nadezhda Pavlovna Paramonova, Todd Parrish St Clair
