Abstract: A system for delivering and applying a flowable mixture to an article (311-313) is disclosed. The system includes a mixture delivery system (200) and a skinning system (300). The mixture delivery system (200) includes a mixer (220) configured to mix a dry material and a fluid to produce the flowable mixture, and a pump (235) configured to pump the flowable mixture to a delivery line. The skinning system (300) receives the flowable mixture from the mixture delivery system (200) through the delivery line. The skinning system (300) includes a skinning pipe (310) configured to apply the flowable mixture to the article (311-313) and a manifold (305) that supports the skinning pipe (310). The skinning system (300) also includes an article feeding mechanism (315) configured to push the article (311-313) into the skinning pipe (310). The skinning system (300) includes a transfer system (320) configured to hold the article (311-313) and move the article (311-313) out of the skinning pipe (310).

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: 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.

Abstract: Disclosed is a honeycomb support structure comprising a honeycomb body and an outer layer or skin formed of a cement that includes an inorganic filler material having a first coefficient of thermal expansion from 25 C to 600 C and a crystalline inorganic fibrous material having a second coefficient of thermal expansion from 25 C to 600 C. Skin cement composition controls level of cement liquid/colloid components, for example water, colloidal silica, and methylcellulose migration into the substrate during the skin application process to form barrier to skin wetting and staining during the washcoating process.
