Publication number: 20220258493Abstract: An inkjet printhead, a system including an inject printhead, and a method for applying primer to a target area on an outer surface of a ceramic body. The inkjet printhead comprises an ink chamber comprising the primer therein. The primer comprises a pigment, a binder, and a solvent. The primer also comprises a surface tension of at least about 40 mN/m. A spray nozzle is connected to the ink chamber and comprises an exit opening that comprises an area of less than about 20,000 square microns. The spray nozzle is configured to eject droplets of the primer from the exit opening at an average exit velocity of less than about 4 m/s.Type: ApplicationFiled: June 28, 2019Publication date: August 18, 2022Inventors: Alexandre Mikhailovich Bratkovski, Kathy Margaret Corcoran, Mariia Andreevna Lapina, Nadezhda Pavlovna Paramonova

Patent number: 10993295Abstract: A microwave mode stirrer apparatus having a stirring member with microwave-transmissive regions is disclosed, along with methods of performing microwave stirring using the microwave mode-stirring apparatus. The microwave-transmissive regions can be in the form of holes or can include microwave-transmissive material. The stirring member can have a variety of configurations, and the microwave-transmissive regions can have a variety of sizes and shapes. A microwave oven that uses the mode stirrer apparatus for drying green ceramic-forming bodies is also disclosed.Type: GrantFiled: September 28, 2016Date of Patent: April 27, 2021Assignee: Corning IncorporatedInventors: Paul Andreas Adrian, James Anthony Feldman, Jacob George, Steffen Georg Klingler, Nadezhda Pavlovna Paramonova, Erwin Josef Wersching

Patent number: 10173933Abstract: 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: GrantFiled: March 31, 2014Date of Patent: January 8, 2019Assignee: Corning IncorporatedInventors: Willard Ashton Cutler, James Anthony Feldman, Jacob George, Amit Halder, Nadezhda Pavlovna Paramonova, Todd Parrish St Clair

Publication number: 20170334091Abstract: Systems and methods for drying skinned ceramic wares (10) using recycled microwave radiation are disclosed. The method includes irradiating wet skinned ceramic wares (10W) in a first applicator section (124W) with microwave radiation (212), wherein said irradiating (212) gives rise to reflected microwave radiation (212R). The method also includes capturing a portion of the reflected microwave radiation (212R) and irradiating a plurality of semi-dry skinned ceramic wares (105) in a second applicator section (124S) with the reflected microwave radiation (212R). Systems for carrying out the method are also disclosed.Type: ApplicationFiled: October 27, 2015Publication date: November 23, 2017Inventors: James Anthony Feldman, Jacob George, Amit Halder, Nadezhda Pavlovna Paramonova

Patent number: 9440373Abstract: Tray assemblies and methods for manufacturing ceramic articles are provided. In one embodiment, a tray assembly includes a tray body having a supporting surface operable to support a ceramic article for passage through a microwave drying apparatus during a microwave drying process and a microwave coupling cover associated with the tray body. The microwave coupling cover envelopes at least a portion of the ceramic article during the microwave drying process. The microwave coupling cover has a dielectric property such that a greater percentage of microwave energy is coupled into the ceramic article with the microwave coupling cover present during the microwave drying process than with the microwave coupling cover not present. Methods may include rotating the ceramic article when the ceramic article is about 40%-60 dry.Type: GrantFiled: March 15, 2013Date of Patent: September 13, 2016Assignee: Corning IncorporatedInventors: James Anthony Feldman, Jacob George, Nadezhda Pavlovna Paramonova, Michael Dean Seymour

Patent number: 9335093Abstract: Systems and methods for efficient microwave drying of extruded honeycomb structures are disclosed. The methods include conveying first and second sets of honeycomb structures in opposite directions through multiple applicator cavities. Each honeycomb structure has a moisture content MC, and the honeycomb structures within each cavity define an average moisture content MCA between 40% and 60% therein. The methods include irradiating the first and second sets of honeycomb structures within the cavities with microwave radiation having an amount of input microwave power PI that results in an amount of reflected microwave power PR from the honeycomb structures, where PR<(0.2)PI. This allows for a relatively high microwave power to be maintained in each cavity. Batch microwave drying methods are also disclosed.Type: GrantFiled: May 6, 2015Date of Patent: May 10, 2016Assignee: Corning IncorporatedInventors: James Anthony Feldman, Jacob George, Amit Halder, Nadezhda Pavlovna Paramonova
