Abstract: Improved inspection techniques are described herein for identifying leaks in a plugged honeycomb body. The improved inspection techniques utilize a pore impediment and a test gas. The pore impediment is injected into the plugged honeycomb body, and the test gas is forced into the plugged honeycomb body. A thermal detector is used to collect thermal data from an inspection region of an outlet end of the plugged honeycomb body, and the thermal data is used to identify defects in the plugged honeycomb body.

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: Defect detection systems include at least one nozzle for delivering a CO2 particulate fluid to an inlet end of a plugged honeycomb body. Defects in the honeycomb, if any, are determined by monitoring CO2 particulate flow at the outlet end of the honeycomb body. Methods for detecting defects in plugged honeycomb bodies are also disclosed.

Abstract: An in situ inspection system and method to inspect a honeycomb body (122) skin in a skinning system. The inspection system includes a line illuminator (148) to generate a line illumination on the skin (136) perpendicular to an axial direction (112) of the honeycomb body travel, and a detector (152) to detect the line illumination scattered from the skin (136) and generate a signal based on the detected line illumination. A controller (184) is configured to receive the signal generated by the detector (152), compare the received signal to a previously stored defect free signal in real-time, and control at least one skinning process parameter based on the comparison. The method includes in situ inspecting the skin (136) and controlling at least one skinning process parameter based on the inspection. In the method, the in situ inspection includes illuminating a line of the skin (136) perpendicular to the axial direction (112) and detecting the illuminated line scattered from the skin (136).

Abstract: Apparatus and methods are disclosed which apply inorganic particles to a plugged honeycomb body comprising porous walls, an inlet end and an outlet end. The apparatus comprises a particle counter and the method comprises counting a selected portion of the inorganic particles from a first sampling port upstream from the plugged honeycomb body and a second sampling port downstream from the plugged honeycomb body. The selected portion of the inorganic particles are in a preselected inorganic particle size range. Filtration efficiency can be determined while inorganic particles are being deposited, for example to increase filtration efficiency.

Abstract: Apparatus and methods are disclosed which are capable of being used to determine filtration efficiency of a filter body even in a clean state. Methods of determining a filtration efficiency of a filter including forcing an inlet flow comprised of a gas (such as air) flow into the inlet end of the filter at a set flow rate, introducing particles such as smoke particles into the inlet flow, and optically counting the number of particles entering and exiting the filter during a sampling event, such as with diffraction based optical particle counters positioned upstream and downstream of the filter. Preferably the gas flow is a soot-free flow stream which does not load the honeycomb filter body with contaminants that need to be removed or burned out. The filter body can thus remain in an essentially clean state even after testing its filtration efficiency.

Abstract: Extrusion techniques for reducing bow of an extrudate formed from a ceramic forming mixture. Velocities of an outer surface of the extrudate are measured at a plurality of peripherally spaced measurement locations. The velocities are compared to determine whether there is a velocity bias, and the comparison is used to selectively alter the flow of the ceramic forming mixture.

Abstract: A method for applying a surface treatment to a plugged honeycomb body comprising porous wall includes: atomizing particles of an inorganic material into liquid-particulate-binder droplets comprised of a liquid vehicle, a binder material, and the particles; evaporating substantially all of the liquid vehicle from the droplets to form agglomerates comprised of the particles and the binder material; depositing the agglomerates onto the porous walls of the plugged honeycomb body; wherein the agglomerates are disposed on, or in, or both on and in, the porous walls.
