Abstract: The invention discloses an artificial epistropheus support body comprising a support. The support comprises a crown part and a body part, a top surface of the crown part forms a top profiling surface, and a bottom surface of the body part forms a bottom profiling surface; the support has a cavity inside thereof, and a micro-hole grid stent is arranged in the cavity; the cavity forms a plurality of windows on the surface of the support. The bottom end of the body part is provided with a lower fixing lug, while the upper end of the crown part is provided with an upper fixing lug; both the lower fixing lug and the upper fixing lug are provided with fixing holes. The artificial epistropheus support body possesses good stability for supporting and reconstructing, it also can prevent a prosthesis from loosening and failing after surgery.

Abstract: The present invention relates to the technical field of polymer composites, in particular to a poly (cyclic butylene terephthalate)/silicon dioxide nanocomposite, wherein the added silicon dioxide is catalyst-modified nanosilicon dioxide.

Abstract: A handheld drain clearing device includes a first compressed air collection chamber and a cylindrical chamber for housing a cylinder. The central axis of said cylindrical chamber coincides with the central axis of said first compressed air collection chamber. A second compressed air collection chamber is formed within said cylindrical chamber and extends into said first compressed air collection chamber. To operate, a user first pushes the air into the second compressed air collection chamber, and then further pushes said cylinder inward to force said compressed air through a gate, into the first compressed air collection chamber. Finally, use a trigger component to discharge the highly compressed air to clear the blockage.

Abstract: A method comprises storing data relating to the wear of a component of at least one turbine system in a database of a system for processing wear related information, generating a displayable menu containing a plurality of user-selectable links respectively associated with software modules of the system, and receiving an on-line selection of one of the user-selectable links to enable the associated software module of the system to generate displayable content including information relating to the wear of the component of the turbine system. The selected module may enable a quantitative amount of the wear of the component or qualitative wear range characterizing the amount of the wear of the component to be input and received on-line. Alternatively, the selected module may enable a component type to be input and received on-line and display a component fleet leader.
