Other Related Research

Abstract

The invention relates to an apparatus that acts as a fail save shut off valve. More specifically, the invention relates to a fail save shut off valve that allows fluid flow during normal operational conditions, but prevents the flow of fluids in the event of system failure upstream that causes over-pressurization. The present invention is particularly well suited for use in conjunction with hot gas filtering systems, which utilize ceramic candle filters. Used in such a hot gas system the present invention stops the flow of hot gas and prevents any particulate laden gas from entering the clean side of the system.

Cermet materials, self-cleaning cermet filters, apparatus and systems employing same

Patent Kong, Peter C.

A self-cleaning porous cermet material, filter and system utilizing the same may be used in filtering particulate and gaseous pollutants from internal combustion engines having intermetallic and ceramic phases. The porous cermet filter may be made from a transition metal aluminide phase and an alumina phase. Filler materials may be added to increase the porosity or tailor the catalytic properties of the cermet material. Additionally, the cermet material may be reinforced with fibers or screens. The porous filter may also be electrically conductive so that a current may be passed therethrough to heat the filter during use. Further, a heatingmore » « less

Lift-off patterning processing employing energetically-stimulated local removal of solid-condensed-gas layers

Patent Branton, Daniel; Golovchenko, Jene A.; King, Gavin M.; ...

The invention provides a method for forming a patterned material layer on a structure, by condensing a vapor to a solid condensate layer on a surface of the structure and then localized removal of selected regions of the condensate layer by directing a beam of energy at the selected regions, exposing the structure at the selected regions. A material layer is then deposited on top of the solid condensate layer and the exposed structure at the selected regions. Then the solid condensate layer and regions of the material layer that were deposited on the solid condensate layer are removed, leavingmore » « less

Method of lift-off patterning thin films in situ employing phase change resists

Patent Bahlke, Matthias Erhard; Baldo, Marc A; Mendoza, Hiroshi Antonio

Method for making a patterned thin film of an organic semiconductor. The method includes condensing a resist gas into a solid film onto a substrate cooled to a temperature below the condensation point of the resist gas. The condensed solid film is heated selectively with a patterned stamp to cause local direct sublimation from solid to vapor of selected portions of the solid film thereby creating a patterned resist film. An organic semiconductor film is coated on the patterned resist film and the patterned resist film is heated to cause it to sublime away and to lift off because ofmore » the phase change. « less
