Abstract: An expandable implant may include an expandable body defined by a superior endplate and an inferior endplate that are hingedly coupled and may be expanded and lordosed. The superior endplate may include a first core having a distal engagement surface and the inferior endplate may include a second core having a proximal engagement surface and a threaded screw aperture. The implant may include a threaded breakoff screw disposed in the threaded screw aperture and movable between a locked position and an unlocked position, for example. In the locked position, the threaded locking screw may urge the distal engagement surface of the first core into direct contact with the proximal engagement surface of the second core. When broken, the breakoff screw may comprise a recessed fracture surface.

Abstract: An expandable implant may include an expandable body defined by a superior endplate and an inferior endplate that are hingedly coupled and may be expanded and lordosed by an external surgical tool. The superior endplate may include a first core having a distal engagement surface and the inferior endplate may a second core having a proximal engagement surface and a threaded screw aperture. The implant may include a threaded locking screw disposed in the threaded screw aperture and movable between a locked position and an unlocked position, for example. In the locked position, the threaded locking screw may urge the distal engagement surface of the first core into direct contact with the proximal engagement surface of the second core. The implant may include a pair of mounting tangs that may be sheared off and/or recesses. The locking screw may be a break-off screw.

Abstract: An apparatus for recovering a grannular material which is dispensed onto articles to be coated by the grannular material in an enclosure but not all of which grannular material adheres to the articles. The apparatus includes a belt of a material which is essentially impermeable to the grannular material, and a pair of rolls about which the belt is trained. The rolls extend generally horizontally and generally parallel to each other. The belt has a vertically upper, generally horizontal run and a vertically lower, generally horizontal run. The vertically upper run of the belt is exposed to the interior of the enclosure. The non-adherent material is deposited onto the upper run. A hopper for recovering the non-adherent material deposited on the upper run is provided adjacent and vertically below the rolls. A prime mover is coupled to the rolls to cause non-adherent grannular material to be conveyed to the hopper.
