Abstract: An aircraft comprises a plurality of spanner bars. Each spanner bar has a pattern of mounting holes separated by lands. A plurality of nut plates engage the spanner bars. Each nut plate includes a body having a mounting surface against one of the spanner bars; and first and second posts extending from the mounting surface and through respective holes in the corresponding spanner bar. Each post has an undercut portion that abuts against one of the lands. Each nut plate further includes a locking member occupying a space between one of the posts and the lands to prevent the nut plate from disengaging the corresponding spanner bar.

Abstract: The present invention provides novel filled silicone compositions comprising a nano-particulate metal oxide filler selected from nano-particulate monoclinic alpha-phase bismuth oxide, nano-particulate erbium oxide, and mixtures thereof. The new composite compositions exhibit a combination of outstanding performance characteristics in both the cured and uncured states. Thus, the uncured formulations are typically free flowing liquids which are self-leveling, which de-gas readily under vacuum, are readily colorable through the addition of pigments, and which cure at temperatures of about 60° C. The cured compositions possess outstanding acoustic characteristics which make them ideally suited for use in applications such as acoustic lenses for medical imaging and therapy. For example, the acoustic impedance of compositions provided by the present invention is closely matched to the acoustic impedance of human tissue.

Abstract: An access chamber assembly for use in a pneumatic transport system with a sealing arrangement that provides an intended bearing clearance relative to an access door device which is rotated between an open, access state and a closed state. The bearing clearance allows for radial adjustment of the door while being rotated between states of being fully closed and fully open to avoid binding and seal friction noise.

Abstract: A digital strapping system comprising an alternatively configurable hallux strap system for positioning and exercising a hallux of a foot, and/or an alternatively configurable osteotomy strap system for positioning and exercising a second and/or third digit of a foot.

Abstract: An implant for metatarsal hemiarthroplasty according to embodiments of the present invention includes a resurfacing body configured to at least partially resurface distal and dorsal surfaces of an articular head of a metatarsus, the resurfacing body including a first side and a second side, the first side configured to articulate against a phalange associated with the metatarsus, the first side including a convex surface formed of ceramic, the second side configured to be fixed to the metatarsus, the second side including a concave surface from which protrude at least two immobilization elements, the at least two immobilization elements configured to interface with the articular head.
