Publication number: 20220332012Abstract: An extrusion system (100) according to certain aspects includes at least one infrared emitting device (102) arranged in a generally cylindrical shape with a hollow interior. The at least one infrared emitting device (102) is positioned downstream of an outlet of an extrusion die (110) to irradiate a perimeter of wet extrudate material in a uniform manner to form stiffened wet extrudate material (116) before such material is received by an extrudate support channel (118). The at least one infrared emitting device (102) generally uniformly stiffens the skin of the wet extrudate material (116) to resist mechanical deformation of the extrudate material during subsequent handling steps. Such skin stiffening allows for increased tolerance of handling forces and permits extrusion of softer wet extrudate material without compromising the shape of a fired ceramic product.Type: ApplicationFiled: August 7, 2020Publication date: October 20, 2022Inventors: Ravindra Kumar Akarapu, Priyank Paras Jain, Xinghua Li, John Forrest Wight, Jr.

Patent number: 7575793Abstract: A radial cell ceramic honeycomb structure is provided that is particularly adapted for use as a catalytic carrier or a particulate filter in an automotive or diesel exhaust system. The honeycomb structure includes a network of interconnected webs having a central axis. The network of webs includes radial webs of varying lengths, only some of which substantially extend the entire radial length of the network, and tangential webs that intersect to define rings of gas-conducting radial cells, and a rounded outer skin that surrounds the cells formed by the interconnected webs. The radial webs extending to the periphery of the network join an inner edge of the outer skin in a substantially orthogonal orientation to reduce thermally generated stresses and to increase strength of the resulting structure. The number of radial webs in the network changes along the radial length at transition zones that are defined by one of the tangential webs such that a desired cell density is achieved across the network.Type: GrantFiled: March 31, 2006Date of Patent: August 18, 2009Assignee: Corning IncorporatedInventors: Kenneth William Aniolek, Douglas Munroe Beall, Priyank Paras Jain, Kenneth Richard Miller, Seth Thomas Nickerson, Alan Thomas Stephens, II
