Abstract: 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.

Abstract: 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.

Abstract: Transparent or translucent sound diffuser-absorbers include a first glass sheet of less than 0.8 mm thickness and a second glass sheet of less than 0.8 mm thickness with a transparent or translucent adhesive layer there between, the adhesive layer adhering the first and second sheets in a fixed configuration such that a first major surface of the first glass sheet has a smooth, repeatedly rising and falling shape. The diffuser-absorbers further include a plurality of through-holes extending through the first glass sheet and through the adhesive layer and through the second glass sheet. Methods of forming are also disclosed.

Abstract: Methods, systems, and devices for ultrasonic inspection for ceramic structures are described. The method may include transmitting, via an ultrasonic transmitter, an ultrasonic waveform through the ceramic structure, where the ceramic structure includes two opposing ends and one or more outer faces extending between the two opposing ends, the one or more outer faces being at least partially enclosed by a casing and the ultrasonic transmitter being positioned adjacent to a first of the two opposing ends. The method may also include receiving a propagated waveform via an ultrasonic receiver positioned adjacent to a second of the two opposing ends and generating an image based at least in part on the propagated waveform, the image illustrating at least a portion of the casing and one or more detected features of the ceramic structure at the one or more outer faces of the ceramic structure adjacent to the casing.
