Abstract: Electromagnetic (EM) drying of a plugged ware is provided that includes subjecting the ware to an axially non-uniform EM radiation field that causes more EM radiation to be dissipated in either of the plugged regions than in the unplugged region. The EM radiation field is provided by a configurable applicator system that includes a feed waveguide and a conveyor path. The feed waveguide includes configurable slots. The configurable applicator system can be set to selectively vary the amount of EM radiation dissipated by each ware along the longitudinal axis of each ware as a function of ware position along the conveying path, thereby enhancing the EM drying process.

Abstract: A plugging apparatus for plugging channels in a honeycomb structure used to form a particulate filter. The apparatus includes an extrusion apparatus that holds plugging material and that has an opening through which the plugging material is extruded. An extrusion plate having first through holes that correspond in location to a subset of honeycomb channels is arranged adjacent the opening. An annular flow plate is operatively arranged face-to-face with the extrusion plate. The annular flow plate has second through holes corresponding in location to the first through holes but that are smaller to compensate for a radial variation in the extrusion rate when plugging the channels in the honeycomb structure. The plugging apparatus is thus able to fill select channel ends with same-size plugs, which leads to a better-performing filter.

Abstract: A fast light off flow-through ceramic substrate is provided that is particularly adapted for use as a catalytic converter. The substrate is formed from a body of ceramic material having axially opposing inlet and outlet ends for receiving and expelling the flow of automotive exhaust gas, respectively. The body contains a network of walls coated with a catalyst that define axially-oriented flow-through cell channels. The average thermal mass (ATM1) of a first axial region of the walls adjacent to the inlet end is at least 20% less than the average thermal mass (ATMTOT) of all of the walls. The lower average thermal mass of the walls in the first region advantageously shortens the light off time for the catalyst within the substrate to effectively neutralize automotive pollutants. The reduction of the average thermal mass in only the first axial region of the walls advantageously maintains the strength of the resulting body of ceramic material, and further increases the cool down time of the body.
