Patent number: 9308584Abstract: Sintered fiber filters are provided that can afford high particle capture efficiency and/or low pressure drop during operation, and are useful in applications such as semiconductor processing. The shape of at least a portion of the individual fibers (e.g., metal fibers) used to make the filter have a three-dimensional aspect, which allows for a low packing density and high porosity filtration media. Certain filters have a cylindrical or tube-like shape with tapered ends of higher density. Methods of making such filters, for example, using axial pressing, are also described.Type: GrantFiled: January 22, 2014Date of Patent: April 12, 2016Assignee: MOTT CORPORATIONInventors: Derek Burgess, Wayne F. White, Alfred M. Romano, Todd W. Pflugbeil, Richard D. Balazy, Kenneth L. Rubow, John E. Rosenberger

Patent number: 6802333Abstract: A method and system for controlling the rate of fluid flow. A flow restrictor having known pressure drop and flow rate characteristics provided in a passage through which the fluid, preferably a gas, flows. An upstream pressure sensor determines the pressure of fluid in the flow passage upstream of the flow restrictor. A downstream pressure sensor determines the pressure of fluid in the flow passage downstream of said flow restrictor. A pressure regulator adjusts the pressure of fluid upstream or downstream of the flow restrictor based on the pressure drop across the flow restrictor so that the actual pressure drop across the flow restrictor closely corresponds to the pressure drop associated with a desired rate of fluid flow.Type: GrantFiled: November 1, 2001Date of Patent: October 12, 2004Assignee: Mott Metallurgical CorporationInventors: Richard D. Balazy, Cathy L. Cowan, Mark R. Eisenmann, Kenneth E. Frink, Edward Kulha

Patent number: 5917066Abstract: An inline ultra-high efficiency filter comprising a housing having a chamber extending the length thereof, an inlet and an outlet providing flow passages into and from the chamber. Seated in the chamber is a porous sintered metal filter element having a tubular body open at its end adjacent the inlet and an end wall at its other end adjacent the outlet, and the filter element provides an internal flow passage extending therein from the inlet to the end wall. A sealing weldment provides an air tight seal between the periphery of the filter element and the housing adjacent the inlet. The filter element is spaced from the wall of the chamber to provide a plenum space thereabout, and a gas stream entering the inlet end of the filter passes into the internal flow passage of the filter element and outwardly of the body of the filter element into the plenum space and thence outwardly of the outlet end of the filter.Type: GrantFiled: July 16, 1997Date of Patent: June 29, 1999Assignee: Mott Metallurgical CorporationInventors: Mark R.
