20100126133 | Coated Particulate Filter And Method - A particulate filter is provided having a filter body with at least one porous wall, and a porous coating on the wall, the coating having a median pore diameter less than 20 microns and a coating pore size deviation of less than 3 times the coating median pore diameter, and the coating having an average thickness of less than 50 microns. A method of manufacturing a particulate filter is also disclosed which includes providing a filter body with at least one porous wall, and depositing particles onto the wall, the particles having a mean particle diameter of less than about 30 microns. | 05-27-2010 |
20110041469 | Ceramic Radial Wall Flow Particulate Filter - The present disclosure relates to radial wall flow particulate filters comprised of ceramic material. The filters include a filter body that has a plurality of adjacent troughs circumferentially arranged around a longitudinal axis. | 02-24-2011 |
20110129640 | METHOD AND BINDER FOR POROUS ARTICLES - A method for making porous articles, including: depositing a powder mixture layer comprising a binder powder, and at least one structural powder; contacting the powder mixture layer and an aqueous liquid to selectively activate the binder powder and form a green layer; repeating the depositing and the contacting sequence at least one time; and de-powdering and drying of the resulting green body. The binder powder can include, for example, a protein that is soluble in water at or below about 25° C. The disclosure also provides articles, having high porosity and optionally intricate 3D structures, as defined herein. | 06-02-2011 |
20110318555 | Glass Sheets With Improved Mechanical Strength - Transparent glass sheets having increased mechanical strength include an inner layer surrounded by surface compressive layers wherein the difference of the coefficient of thermal expansion of the inner layer and the surface compressive layer is greater than 50×10 | 12-29-2011 |
20120102706 | Methods of Making Filter Apparatus and Fabricating a Porous Ceramic Article - Methods of making a filter apparatus includes the step of creating a filter stack by axially spacing the porous ceramic plates from one another with a plurality of compliant spacers. In another example, the method includes the step of firing the first filter stack to sinter bond the first plurality of porous ceramic plates together with a first spacing element. In another example, the plurality of plates comprise a composition including catalyst particles and a binder material and the plates are fired to form porous plates without sintering a substantial amount of the catalyst particles. Methods of fabricating a porous ceramic article also include providing a porous substrate with a first material composition including mullite and infiltrating the pores of the substrate with a second material composition including cordierite. The method further includes the step of firing the first composition and the second composition to form the porous ceramic article. | 05-03-2012 |
20120102902 | Filter Apparatus With Porous Ceramic Plates - A filter apparatus comprises a filter stack including a plurality of porous ceramic plates that are axially spaced from one another to define plurality of axially spaced apart radial flow areas. In one example, the filter stack is mounted within a housing. In further examples, the plurality of porous ceramic plates alternate between a first set of porous ceramic plates that are nested with a second set of porous ceramic plates. In still further examples, at least one of the sides of the porous ceramic plates defines a plurality of radial flutes arranged in a radial array. | 05-03-2012 |
20120177831 | METHOD FOR MAKING FUSED CERAMIC ARTICLES OF NEAR NET SHAPE - The invention is a solution impregnation and drying treatment that imparts a high temperature binder into an already formed porous green body composed of particulate batch material. The batch material includes inorganic compounds and binder. The result is reduced sag and distortion and the same or increased strength when the porous body is later fused during sintering/firing. | 07-12-2012 |
