摘要:
In accordance with the present invention a method for the direct manufacture of aerospace duct elements is provided comprising executing a single build run on a build chamber using direct fabrication technology to generate at least one duct section. The at least one duct section is generated by forming a plurality of partial cylinder duct segments orientated within the build chamber in a nested arrangement during the single build run, and assembling at least two of the partial cylinder duct segments to form the duct section. The duct section has a duct cross-sectional profile larger than a build chamber profile.

A smooth side trailer body or body structure comprised of a plurality of extruded panel members positioned adjacent one another. The extruded panels are arranged perpendicular to the floor of a trailer. The panels are held to the floor by a bottom rail. A top rail portion may be used to hold the panels together to form a more rigid wall.

A trailer body includes left and right bottom rails and left and right top rails all parallel to each other. A floor extends between the left and right bottom rails. A left vertical sidewall is defined between the left bottom rail and the left top rail. A right vertical sidewall is defined between the right bottom rail and the right top rail. The sidewalls are defined by a plurality of abutted extruded wall panels that extend vertically between the respective bottom and top rails. The floor is optionally defined by a plurality of abutted and interconnected one-piece extruded floor panels that extend between the left and right bottom rails. The wall and/or floor panels can include an I-beam post/cross-member defined in the extrusion profile. The panels can also define half I-beam post/cross-members so that adjacent abutted panels cooperate to define additional full I-beam post/cross-members.

A multi-section conveyor roller is engageable with a conveyor belt moveably mounted on a conveyor frame assembly. The roller includes a rotatable mounting hub connected to the conveyor frame assembly, and a plurality of adjacently disposed roller segments fixed to the mounting hub to form belt-engaging, curved outer wall surfaces. The outer wall surfaces are separated by a number of gaps, at least one of the gaps receiving rib structure provided on the conveyor belt for maintaining proper movement of the conveyor belt on the conveyor frame assembly.

End portions of face plates 111 and 112 of a frame member 110 are connected by a rib 116A. To protrusion chips 117b1 and 117b2 end portions of face plates 101 and 102 of another frame member 100 are overlapped. The corners between the rib 116A and the rear faces of the face plates 111 and 112 are in the form of a convex circular arc 131 which protrudes into a hollow portion 119 of the frame member 110. Both end portions of the circular arc 131b1 are connected to the rib 116A and the face plates 111 and 112 by two smooth recessed circular arcs 132b1 and 133b1. Accordingly, since a flow-out of metal does not occur from this portion, the cross-section can be small and a light weight structure an be obtained. A structural body formed of hollow frame members which are joined by friction stir welding provides a light weight structure.

An operating system for a safety device in a vehicle including a driving element housed in a guide housing and coupled to a safety device for its operation. A gas generating device generates a gas pressure in the guide housing. A starting device triggers the generating device to generate gas pressure in two successive, but partially overlapping driving stages. A load limiter coacts with the driving element to insure a predetermined yielding performance of the safety device.

A heat exchanger element includes a single and integrally extruded member having at least two hollow tubes having parallel longitudinal axes, each two adjacent hollow tubes being connected by at least two webs which extend parallel to the longitudinal axes and which are formed integrally with each of the two adjacent hollow tubes. The webs have therethrough plural perforations, and the material of each web between adjacent perforations therein is deflected to form a rib extending at an angle to the web. At least one tube has formed integrally therewith a projecting track which extends parallel to the longitudinal axes. Plural heat exchanger elements are connected at the respective tracks thereof to form a tube bundle.
