Publication number: 20230334651Abstract: A method and system for inspecting a honeycomb body. The method includes capturing a first image. Instances of at least one feature in the first image that correlates to a structural characteristic of the honeycomb body are detected. One or more detected instances of the at least one feature identified in the first image are abstracted by creating a graphical representation of each of the one or more detected instances of the at least one feature. A second image is generated by augmenting the first image with the graphical representation in place of or in addition to each of the one or more detected instances of the at least one feature identified in the first image. The second image is analyzed using a machine learning algorithm to classify the honeycomb body with respect to the structural characteristic of the honeycomb body.Type: ApplicationFiled: August 5, 2021Publication date: October 19, 2023Inventors: Jacob George, Byoungseon Jeon, Seth Thomas Nickerson, Hak Chuah Sim

Publication number: 20220236157Abstract: An apparatus and methods for evaluating the radial compressive strength of ceramic honeycomb samples. The apparatus includes a housing defining a testing compartment. A pressure subsystem is configured to introduce a pressurizing fluid into the testing compartment. A flexible member is in fluid communication with the pressure subsystem. The flexible member defines a testing area within the testing compartment configured to receive the ceramic honeycomb sample. The flexible member expands inwardly and subjects the honeycomb sample to a compressive force by engaging against the outer surface of the honeycomb sample when pressurized by the pressurizing fluid. An end cap covers an end face of the ceramic honeycomb sample when the ceramic honeycomb sample is positioned in the testing compartment. An acoustic sensor disposed on the end cap is configured to translate acoustic waveforms propagating through the acoustic sensor to a signal representative of the acoustic waveforms.Type: ApplicationFiled: May 13, 2020Publication date: July 28, 2022Inventors: Krishna Sastry Aravelli, Achim Karl-Erich Heibel, Seth Thomas Nickerson, Mitchell E Smith, Prashanth Abraham Vanniamparambil

Patent number: 7575793Abstract: A radial cell ceramic honeycomb structure is provided that is particularly adapted for use as a catalytic carrier or a particulate filter in an automotive or diesel exhaust system. The honeycomb structure includes a network of interconnected webs having a central axis. The network of webs includes radial webs of varying lengths, only some of which substantially extend the entire radial length of the network, and tangential webs that intersect to define rings of gas-conducting radial cells, and a rounded outer skin that surrounds the cells formed by the interconnected webs. The radial webs extending to the periphery of the network join an inner edge of the outer skin in a substantially orthogonal orientation to reduce thermally generated stresses and to increase strength of the resulting structure. The number of radial webs in the network changes along the radial length at transition zones that are defined by one of the tangential webs such that a desired cell density is achieved across the network.Type: GrantFiled: March 31, 2006Date of Patent: August 18, 2009Assignee: Corning IncorporatedInventors: Kenneth William Aniolek, Douglas Munroe Beall, Priyank Paras Jain, Kenneth Richard Miller, Seth Thomas Nickerson, Alan Thomas Stephens, II
