The present invention provides steel sheet products having controlled compositions that are subjected to two-step annealing processes to produce sheet products having desirable microstructures and favorable mechanical properties such as high strength and ultra-high formability. Steels processed in accordance with the present invention exhibit combined ultimate tensile strength and total elongation (UTS • TE) properties of greater than 25,000 MPa-%. Steels with these properties fall into the category of Generation 3 advanced high strength steels, and are highly desired by various industries including automobile manufacturers.

An improved device (10) for simulating gravel impact damage on panels (40), such as protected and unprotected areas of painted vehicle panels, is disclosed. The gravel impact damage simulator (10) includes an enclosure (12), a gravel inlet port having an extension spout (22), a motor-driven rotatable impeller (30) below the inlet port, a downwardly angled baffle (24) between the inlet port and the impeller (30), and a test panel slot (20) through which a test panel (40) may be inserted into the enclosure (12). During operation, gravel is introduced through the extension spout (22) and inlet port. The gravel drops into the angled baffle (24), where it is directed toward the rotating impeller (30). The rotating impeller (30) strikes the gravel and projects it toward the test panel (40).
摘要:
Panoramic optical systems (20, 120) are disclosed comprising an ellipsoidal mirror (1, 101) and a lens system (21, 121) that reduces astigmatism. The lens systems (21, 121) are capable of operating at fast speeds. Simple and highly manufacturable lens systems are provided for capturing and/or projecting high quality 360-degree panoramic scenes.

Expandable spinal implants (10) and drivers (20) connected by a bendable joint (30) are disclosed. The flexible connector (30) allows the implant (10) and driver (20) to move to different angular orientations with respect to each other, and to apply rotational force or torque from the driver (20) to the implant (10) and its expansion mechanism. During insertion of an implant (10) into the desired position, the driver (20) may be oriented in the same or different direction than the long axis of the implant (10). After the spinal implant (10) is placed in the desired position, the driver (20) is used to expand the implant in selected dimensions.
摘要:
Al-Mg-Ag wrought products and methods of making such products useful in aircraft applications. The Al-Mg-Ag wrought products have improved strength when compared to traditional AA5XXX alloys. The alloys may comprise from about 3.5 to about 10 weight percent Mg, from about 0.05 to about 0.5 weight percent Ag, from about 0.01 to about 1.0 weight percent Mn, from about 0.01 to about 0.15 weight percent Zr, and the remainder Al and incidental impurities. In addition, from about 0.05 to about 0.4 weight percent Sc may be added to further improve the strength characteristics.
摘要:
Friction stir processing is applied to an aluminum-scandium alloy workpiece in either a wrought or cast state including scandium-containing precipitates. The process Selectively modifies the microstructure of the aluminum-scandium workplace, for example, by reducing grain size and recrystallization of the substrate. Benefits include increased physical properties of the aluminum-scandium alloys as well as the ability to form unique alloy structures.
摘要:
A device (10) for alternately applying pressure and vacuum to pipes (42) in order to remove or prevent build-up of undesirable coatings inside the pipes is disclosed. The device (10) includes a pressure and vacuum source (340) connected to a plenum (60) having a hose (30) attached to the plenum (60) at a proximal end (31) and a control mechanism (320) attached to the hose (30) near a distal end (32). The control mechanism (320) is operable to control the plenum (60) to rapidly switch between variable amounts of vacuum and pressure to the hose (30). The plenum (60) may also be controlled to supply neither vacuum nor pressure to the hose. The device (10) may be used in a wide variety of settings, including industrial, commercial, marine hospitality industry, and household settings.
摘要:
A protective eye mask (10) for sports use, without a helmet, includes one or more substantially horizontal frame members (28) forming an eye mask frame, defining a cage to protect an area around a user's eyes, the eye mask frame having at least an upper frame segment (44) and a lower frame segment (46), the frame members having an inside facing towards the user's eyes and an outside facing away therefrom; one or more substantially horizontal frame members (28) arranged between the upper (44) and lower frame segments (46); one or more substantially vertical frame members (26) continuous with or rigidly attached to one or more of the substantially horizontal frame members (28); a contact material (30) for contacting the user's face area, attached to the eyewear frame; and a mechanism for securing (36) the protective eye mask to the user's face.
摘要:
Integrally stiffened extruded metal panels (22, 30) for ground vehicles (10) are provided. The panels (22, 30) may be extruded in the form of a tube (21), then cut and un-rolled to provide the desired shape, e.g., for a sidewall or top wall of a ground vehicle such as a railway car (10). In a preferred embodiment, the integrally stiffened extruded panels (22, 30) have widths and lengths sufficient to cover substantially the entire height and length of the ground vehicle, thereby eliminating seams along the sidewalls of the vehicle (10).
