Articulatable fume exhauster trunk

Abstract: Fumes are drawn by a vacuum source from a scoop through conduit. The conduit provides its own structure with rigid tubes and which are held with respect to one another, a mounting collar and the scoop by joint attaching assemblies and. In this way, the fume exhauster requires minimal structure. Also, joint assemblies minimize flow resistance since they are located along inside conduit curvatures.

Polymer, polymer microfiber, polymer nanofiber and applications including filter structures

Abstract: Disclosed are improved polymer materials. Also disclosed are fine fiber materials that can be made from the improved polymeric materials in the form of microfiber and nanofiber structures. The microfiber and nanofiber structures can be used in a variety of useful applications including the formation of filter materials.

Air filtration arrangements having fluted media constructions and methods

Abstract: Filter arrangements include a barrier media in the form of fluted media treated with a deposit of fine fibers. The media is particularly advantageous in high temperature (greater than 140 to 240° F.) systems. Such systems may include engine systems, gas turbine systems, and fuel cell systems. Filter arrangements may take the form of media packs having a circular cross-section or a racetrack shaped cross-section, or media packs formed in a panel configuration.

Filter material construction and method

Abstract: A preferred filter media is provided. The media includes a fine fiber web secured to the surface of a coarse fiber support. A preferred filter media, comprising multiple layers of fine fiber media separated by coarse fiber support, is provided. Advantageous filter constructions result and are provided. Also according to the disclosure, methods for using such arrangements to filter are provided.
