Publication number: 20210046675Abstract: Disclosed are methods related to making a stamped article and articles and assemblies made therefrom. The methods include providing a partial replica of the stamped article having opposed first and second major surfaces, and then coupling the partial replica to a walled enclosure to provide a mold assembly having upper and lower chambers separated from each other by the partial replica. Compositions can be hardened in the upper and lower chambers to provide upper and lower tools having a shape complemental to the first and second major surfaces. After removing the upper and lower tools from the mold assembly, a deformable sheet can be pressed between the upper and lower tools to form the stamped article.Type: ApplicationFiled: April 19, 2019Publication date: February 18, 2021Inventors: Charles W. Hedley, Donald A. Eckstein, Jay A. Esch, Christopher Kelton, Fredrick W. Vance

Patent number: 7497952Abstract: A method for removing dissolved contaminants from solution using a surface-activated crystalline titanium oxide product having a high adsorptive capacity and a high rate of adsorption with respect to dissolved contaminants, in particular, arsenate and arsenite. Preferably, the titanium oxide product includes crystalline anatase having primary crystallite diameters in the range of 1-30 nm. The surface-activated titanium oxide is combined with other filter media to further improve the removal of dissolved contaminants.Type: GrantFiled: July 7, 2005Date of Patent: March 3, 2009Assignee: The Trustees of Stevens Institute of TechnologyInventors: Xiaoguang Meng, Mazakhir Dadachov, George P. Korfiatis, Christos Christodoulatos, David J. Moll, Geofrey Paul Onifer, Daniel B. Rice, Robert E. Reim, Fredrick W. Vance, Harlan Robert Goltz, Chan Han, William I. Harris

Patent number: 6840976Abstract: A ceramic honeycomb wall-flow filter is prepared by plugging channels in a clay containing ceramic honeycomb by a method that has the following steps. First, a mixture of a dispersing liquid and ceramic powder is formed. Second, the mixture is inserted into at least one channel of a clay containing green ceramic honeycomb to form a plugged green ceramic honeycomb wherein the dispersing liquid essentially fails to swell the clay. Alternatively, the mixture is inserted into a calcined ceramic honeycomb to form a plugged calcined ceramic honeycomb. Finally, the plugged green or calcined ceramic honeycomb is heated to a temperature sufficient to sinter the plugged green ceramic honeycomb to form a porous sintered plugged ceramic honeycomb. The method is particularly useful for simultaneously making the plugs and discriminating layers in the channels.Type: GrantFiled: April 23, 2002Date of Patent: January 11, 2005Assignee: Dow Global Technologies Inc.Inventors: Fredrick W. Vance, Sten A. Wallin
