  • Publication number: 20150135667
    Abstract: A skinning apparatus and a method of skinning a porous ceramic. The apparatus includes an axial skinning manifold. The axial skinning manifold includes a curved adaptive pipe to flow cement in a circumferential direction from an inlet at a first position and through an adaptive opening along an inner bend of the curve through a land channel disposed along the inner bend. The land channel emits the cement at a constant velocity from a land opening extending proximate the first position to a second position spaced apart from the first position. The land outlet emits cement at a constant velocity around the outer periphery of the porous ceramic to dispose a uniform skin thereon as the porous ceramic moves axially relative to the land outlet.

  • Publication number: 20150105896
    Abstract: A process for operating an axial skinning apparatus for continuous manufacture of skinned ceramic honeycomb parts, including: determining the physical process parameters of the apparatus including: the rheology of the flowable skin cement; the geometry of the part to be skinned; and the geometry of the annulus gap of the skinning chamber; and calculating a plurality of dimensionless pressure gradient values (Lambda (?)) according to the formula (1): ? = ( ? ? ? P ) ? R 2 ? m ? ? L ? ( R V ) n ( 1 ) where ?P, P, R, V, L, and m and n are as defined herein; plotting a plurality of manifold pressures versus a plurality of part velocities; and selecting at least one operating window based on the skin quality of a plurality of preliminarily skinned parts.

  • Publication number: 20140144212
    Abstract: Methods of testing a honeycomb filter include the step of maintaining an average temperature of the honeycomb filter and/or fog within a range of from about 10° C. to about 30° C. and flowing a fog with moisture droplets into the honeycomb network of channels at the first end portion of the honeycomb filter, the fog including a relative humidity of at least 80%. In further examples, the moisture droplets include a mean droplet size of from about 1 micron to about 25 microns.

  • Publication number: 20140144211
    Abstract: Methods of testing a honeycomb filter for defects include the step of wetting at least one of the first end portion and the second end portion to provide at least one wetted end portion. The method further includes the step of monitoring the second end portion for fog passing through the filter.

  • Publication number: 20130300025
    Abstract: A method of forming a solid layer of a semiconducting material on an external surface of a treated mold which extends between a leading edge and a trailing edge comprises selectively modifying a temperature gradient of a mold such that a temperature of the leading edge (T1) is less than a temperature of the trailing edge (T2) to form the treated mold. The method further comprises submersing the treated mold into a molten semiconducting material such that the leading edge of the treated mold is first submersed into the molten semiconducting material. The method also comprises withdrawing the treated mold from the molten semiconducting material to form the solid layer of the semiconducting material on the external surface of the treated mold.
