摘要:
Aluminum sheet products having highly anisotropic grain microstructures and highly textured crystallographic microstructures are disclosed. The products exhibit improved strength and improved resistance to fatigue crack growth, as well as other advantageous properties such as improved combinations of strength and fracture toughness. The sheet products are useful for aerospace and other applications, particularly aircraft fuselages.

Stabilizer members for bicycle carriers often utilize a spool or hourglass shape that cannot accommodate different cross-sectional sizes of seat tube. This can often result in difficulties in adequately securing the bicycle to the bicycle carrier, and, therefore may result in damage to the bicycle, bicycle carrier, or even the vehicle. Accordingly, the bicycle carrier disclosed herein comprises a support member, a bracket attached to the support member, and a stabilizer member rotatably attached to the bracket, the stabilizer member including first and second faces, the first and second faces each including a channel having a radius of curvature wherein the radius of curvature of the first face is different than the radius of curvature of the second face.

An exhaust processor (12) comprises an isolated interior volume (16) that is defined in a housing (18) of the exhaust processor (12) so as to be isolated from exhaust gas in the housing (18). A motion converter (20) is positioned in the isolated interior volume (16) and is configured to convert in the isolated interior volume (16) linear movement of a linear valve actuator (22) into rotation of an exhaust valve (17). A cushioning pad (120, 122, 320, 420) can be used in a variety of exhaust processors (12, 212) to facilitate positioning of the exhaust valve (17). An associated method is disclosed.

A muffler assembly includes first and second muffler components that are each formed as a single piece. The first muffler component includes a first outlet pipe portion, a first bypass pipe mount portion, and a first resonator shell portion. The second muffler component includes a second output pipe portion, a second bypass pipe mount portion, and a second resonator shell portion. The first and second muffler components are positioned in an overlapping relationship such that respective portions are aligned with each other to form an outlet pipe, a bypass pipe mount, and a resonator shell. A noise attenuation valve assembly is also installed within the first and second muffler components. The bypass pipe mount is positioned at a non-perpendicular orientation relative to the outlet pipe such that a bypass pipe having a straight end mount can be received within the bypass pipe mount to bypass the noise attenuation valve assembly.

A process for improving 6XXX alloys, such as 6013, preferably includes heating, hot rolling, inter-rolling thermal treatment at a very high temperature such as 1020° F. or more, again hot rolling (with or without subsequent continuous hot rolling or cold rolling or both), solution heat treating and artificial aging. The initial heating, inter-rolling, thermal treatment and solution treatment, especially the latter two, are carried out at very high temperatures such as 1030° F. Each aforesaid hot rolling stage produces substantial metal thickness reduction. The improved sheet or plate product has a substantially reduced occurrence of reduced density features revealed in scanning electron microscope examination at 500X and exhibits improved (reduced) fatigue crack growth rate providing an advantage in aerospace applications such as fuselage skin, especially fuselage belly skin.

Disclosed is an aluminum alloy suitable for high temperature applications comprised of at least 9 wt. % Si, 3 to 7 wt. % Ni, 1.5 to 6 wt. % Cu, at least one of the elements selected from Mg, Mn, V, Sc, Fe, Ti, Sr, Zn, B and Cr, the remainder aluminum and impurities.
摘要:
By using a spun extrusion method to form a side entry exhaust inlet, a muffler can be completely stuffed and end caps can be spun onto opposing ends of the muffler on a high speed production line without interruptions. The side entry exhaust inlet is formed within a muffler shell at a position between the opposing ends. A spinning tool engages an internal peripheral area of the side entry exhaust inlet to form a spun extruded surface that extends outwardly from the muffler shell.
