摘要： A honeycomb plugging apparatus that reduces slumping of the plugging patty. Honeycomb plugging apparatus includes a plugging head having an open-ended cavity formed from an end wall and a peripheral wall, and a support substructure provided in the open-ended cavity. Methods of plugging and manufacturing honeycomb bodies using the honeycomb plugging apparatus are provided, as are other aspects.

摘要： Inspection methods, apparatuses, and techniques are described herein for identifying defects in a plugged honeycomb body (100). The inspection apparatuses and methods herein utilize reduced distortion imaging to identify the defects in the plugged honeycomb body. Backlit and/or directly illuminated images (by e.g. first light source 308) of the plugged honeycomb body (100) can be captured (by e.g. camera 302) and analyzed to align (by e.g. actuators 306) the plugged honeycomb body (100) in an imaging apparatus and to identify the defects.

摘要： A method of plugging a permeable porous cellular body (14) comprises: contacting the permeable porous cellular body (14) with a plugging mixture (100), the permeable porous cellular body (14) defining a plurality of channels (26); forcing the plugging mixture (100) into the plurality of channels (26) until a maximum, self-limiting, depth (114) of plugging mixture (100) is disposed within the plurality of channels (26); and maintaining a constant flow rate of the plugging mixture (100) into the plurality of channels until (26) a pressure on the plugging mixture (100) elevates to a predetermined pressure. Alternatively, the method comprises forcing the plugging mixture (100) into the plurality of channels (26) utilizing the application of a constant pressure over time until a maximum, self-limiting, depth (114) of the plugging mixture (100) is disposed within the plurality of channels (26); and maintaining the constant pressure applied to the plugging mixture (100) until flow of the plugging mixture (100) into the channels (26) decays from an initial flow rate to a predetermined flow rate.
