20110056583 | MULTI-WALLED TUBE AND METHOD OF MANUFACTURE - A method of forming multi-wall tube from a single-wall piece of tube. The multi-wall tube is formed by relative motion between a die shoe and the single-wall tube to deform the material. | 03-10-2011 |
20110240165 | MOUNTING MAT AND POLLUTION CONTROL DEVICE WITH THE SAME - Non-woven mat including basalt and amorphous refractory ceramic fibers, bio-soluble ceramic fibers, and/or heat-treated silica fibers. Embodiments of the non-woven mat surprisingly have a Resiliency Value after three thermal cycles from 25° C. to 700° C./400° C. of the Real Condition Fixture Test at least 1.1 times greater than the Resiliency Value of a comparable non-woven mat consisting of any individual type of fibers of the non-woven mat. The non-woven mats are useful, for example, in pollution control devices and other thermal insulation applications. | 10-06-2011 |
20130081734 | Electrostatic Bonding of Coaxial Tubing - A method and apparatus for electrostatically bonding coaxial tubing. An outer tube comprises an electrically conductive material and has an inner surface. An inner tube comprises material and has an outer surface. The inner tube and the outer tube are positioned to define a channel. A bridging structure comprising an electrically conductive material is positioned such that the bridging structure forms mechanical contact and an electrostatic connection between electrically conductive material on the tubes. The bridging structure is in mechanical contact with the inner surface of the outer tube at a first plurality of points and in mechanical contact with the outer surface of the inner tube at a second plurality of points. | 04-04-2013 |
20130126034 | EXHAUST SUBSYSTEM WITH POLYMER HOUSING - A vehicle exhaust system includes a subsystem having an exterior pipe formed of a polymer. A rigid liner extends along the length of the exterior pipe and defines a passageway. A fiber insulating layer is formed between the rigid liner and the exterior pipe. The liner is formed to define at least one groove circumscribing the periphery of the passage-way. The groove defines a region of increased volume of the exhaust passage along the length. The liner is further formed to define at least one void extending between the wall of the liner and the insulating layer, around the periphery of the passageway. A plurality of apertures in the liner, allow sound waves to pass from the passageway into the fiber insulating layer, and into the void. | 05-23-2013 |
20130312865 | DOUBLE-WALL PIPE AND PRODUCTION PROCESS - A double-wall pipe for a transportation means which includes an outer pipe and an inner pipe extending therein. The outer pipe has two pipe segments which are formed like half-shells and are joined together to form the outer pipe along the longitudinal edges thereof. In this way, it is possible to make both the outer pipe and the inner pipe of metal, such that the wall thickness of the inner pipe can be relatively small. | 11-28-2013 |
20140020785 | EXHAUST CONDUCTING DEVICE AND METHOD FOR PRODUCING SAME - An exhaust-gas conducting device of a vehicle has a cylindrical outer housing which is comprised of an outer shell and an inner shell arranged in an interior of the outer shell. The outer shell forms a larger portion of an outer circumference than the inner shell, or forms an equally large outer circumferential portion. A radial outside of the inner shell is attached to the outer shell, in particular by a material-to-material connection. The outer shell is C-shaped in cross-section, or extends in an annularly closed manner. | 01-23-2014 |
