Implantable devices for placement at a cavity or opening such as an aneurysm are disclosed. The implantable devices, in a deployed condition, have a generally inverted U-shaped profile with a curved or angled framework support structure sized and configured for placement in proximity to tissue surrounding the opening and anchoring legs extending proximally from the framework structure sized and configured to contact the wall of a neighboring lumen at opposed locations. Occlusive and semi-occlusive membranes may be associated with the framework support structure and deployed over the opening to provide exclusion of the opening and flow diversion. Proximal anchoring segments providing additional lumen wall surface area contact for the implantable device following deployment may be incorporated.

A selectively detachable container lid includes a center panel and a peripheral sealing lip surrounding the panel. The peripheral sealing lip has a generally inverted U-shaped cross section so as to define a channel into which a bowl rim fits. The lid also includes at least one ridge formed between the panel and the peripheral sealing lip. The ridge is interrupted by at least one gap. The ridge and the peripheral sealing lip partially overlap when viewed in a direction substantially normal to the panel. The ridge also abuts the bowl when the lid is placed loosely on the bowl. Also disclosed is a container that includes such a lid.

The invention discloses a multilayer broadband microstrip antenna, comprising an upper dielectric baseplate, a middle dielectric baseplate, a lower dielectric baseplate, an upper low dielectric constant insulating dielectric layer, a lower low dielectric constant insulating dielectric layer, a reflection plate and a feed probe, wherein rectangle radiators of metallic copper pasters are arranged on the lower surface of the upper dielectric baseplate and the upper surface of the middle dielectric baseplate and provided with U-shaped slot structures with different sizes respectively. Due to a special double-layer inverted U-shaped slot coupling feed way, the symmetry of directional diagrams on an E surface or H surface of the antenna is good, thus ensuring that the antenna has more consistent performances in more directions, and having more actual meanings as an exploration antenna and a communication antenna. The reflection plate with an EBG (electromagnetic band gap) structure can preferably restrain backward radiation in the specified frequency relative to a traditional metal reflection plate, thus improving the directivity of the antenna, thereby further improving the gain of theantenna.

A fluid filter is disclosed which comprises a layer of high loft, non-woven, fibrous, fluid-permeable material having a length and a width, an upper surface, a lower surface, and a thickness measured between the upper and lower surfaces which is non-constant. The non-constant thickness is achieved by providing a series of spaced-apart grooves separated by a series of spaced-apart ridges. The lower surface is substantially planar and the grooves each have a generally U-shaped cross section with the ridges having a generally inverted U-shaped cross section. A modified form of the invention is also disclosed wherein the zones of higher flow resistance have a greater density than the zones of lower flow resistance. In this embodiment, the thickness of the filter is constant. The method of filtering particulate material from a fluid stream is also disclosed.

The invention discloses a square tube multiple face synchronous derusting machine. The derusting machine comprises an inverted-U-shaped rack and is characterized in that an upper motor is fixed to the middle of the upper wall of the inverted-U-shaped rack, and an upper horizontal rotating wire brush is fixed to the lower end of a shaft sleeve of a motor spindle, a fixed belt wheel at the upper end of the spindle is connected with driven shafts outside the left wall and the right wall of the inverted-U-shaped rack for transmission, and the middle of the driven shaft on the left and the middle of the driven shaft on the right are respectively meshed with a shaft end bevel gear of a transverse rotating shaft for transmission through a bevel gear; each transverse rotating shaft is provided with a transverse shaft sleeve connected with the transverse rotating shaft in a matched mode through a spline, and an upper perpendicular face rotating wire brush is fixed to the inner end of each transverse shaft sleeve; idler wheels are arranged at the bottom end of the inverted-U-shaped rack; synchronous rotation of the horizontal rotating wire brush and the perpendicular face rotating wire brushes is achieved through one motor, and thus the upper surface and the two side faces of a square tube can be polished and derusted synchronously. Thus, dust on the surface of the square tube can be cleared away fast with the derusting machine, energy is saved, labor efficiency can be improved, and the using effect of the square tube is improved.

Needle guards are disclosed for use with needle assemblies comprising a needle hub that joins a flexible trailing tube to a medical needle, the normally open front ends of the guards being closeable after a needle and hub have been pulled therein by the trailing tube. In one example (FIG. 4c), a guard (10) has a stiff upper sidewall (24a) of an inverted U-shape and a flexible lower sidewall (26b) that fits inside the upper sidewall and is resiliently biased to bring its front end (31) into contact with the front end (30) of upper sidewall (24b) so as to close the front aperture of the guard after the needle assembly (16) has been withdrawn into the guard. The lower sidewall (26b) can be locked or clipped into the upper sidewall (24b) by pressing lower sidewall passed catches (72). In this way, the needle is completely and safely enclosed after use to reduce the danger of needle-stick injury and blood-splash contamination.
