Patent number: 9908274Abstract: This invention is directed to a microstructured filament that can be used to make fibers having an extruded filament having pre-cooled microfeatures in a radial spiral arrangement about a bore though the filament wherein the microfeature has a width in the range of 25 ?m to 40 ?m and height in the range of 90 ?m to 100 ?m; and, the filament having a post-cooled state having post-cooled microfeatures having physical dimensions smaller than that of the pre-cooled microfeatures. The filament can include microfeatures having a width in the range of 400 nm to 4 ?m and height in the range of 400 nm to 4 ?m. The filament and fiber can include physical characteristics selected from the group consisting of: hydrophobicity, self-cleaning, increased hydro-dynamic drag coefficients, decreased or increased aerodynamic drag coefficients, increased friction, reduced friction, optical effects, increased adhesion, decreased adhesion, oleophobicity, tactile effects, anti-blocking and any combination of these.Type: GrantFiled: July 28, 2015Date of Patent: March 6, 2018Assignee: Hoowaki, LLCInventors: Ralph A. Hulseman, Andrew H. Cannon, William P. King, March Maguire, Carl Hulseman

Patent number: 8720047Abstract: Described herein are casting and molding methods useful for making microstructured objects. By including a plurality of microfeatures on the surface of an object, other characteristics may be imparted to the object, such as increased hydrophobicity. Some of the casting and molding methods described herein further allow for manufacture of objects having both microfeatures and macro features, for example microfeatures on or within macro features or selected macro feature regions.Type: GrantFiled: June 11, 2010Date of Patent: May 13, 2014Assignee: Hoowaki, LLCInventors: Ralph A.

Publication number: 20080236717Abstract: A process for forming a multilayer ceramic capacitor. The process includes depositing a ceramic precursor on a substrate and an electrode ink in a predetermined pattern on the ceramic precursor to form a green sheet. The electrode ink has an adhesion promoter incorporated therein. The green sheet is overlayed with at least one second green sheet to form a layered green sheet which is then fused under pressure.Type: ApplicationFiled: May 7, 2008Publication date: October 2, 2008Inventors: Abhijit Gurav, Azizuddin Tajuddin, Daniel Skamser, Garry Renner, March Maguire, Michael S. Randall, Randal Vaughan

Publication number: 20070227641Abstract: A process for forming a multilayer ceramic capacitor. The process includes forming a ceramic precursor layer and depositing an electrode precursor in a predetermined pattern on the ceramic precursor layer to form a first patterned sheet. A flowable ceramic precursor is applied to the first patterned sheet. At least one second patterned sheet is applied to the first patterned sheet to form a layered patterned sheet and the layered patterned sheet is laminated.Type: ApplicationFiled: April 4, 2006Publication date: October 4, 2007Inventors: Daniel Skamser, Randal Vaughan, March Maguire, Michael Randall, Gregory Crosby
