Abstract: A tool for applying a corrosion-protection substance to a rail for securing seats in an aircraft. The tool includes a component of elongate overall shape, with a base configured to slide along the rail, and a rollers support connected to the base. The tool also has an axle incorporated in the rollers support, which extends transversally with respect to the longitudinal direction of the component on each side of the rollers support, and rollers for applying the substance mounted on the transverse axle, one on each side of the component. The tool allows the substance to be applied effectively to the flange parts of the rail that is to be protected.

Abstract: The disclosure herein relates to a tool for applying a corrosion-protection substance to a rail for securing seats in an aircraft. The tool comprises a component of elongate overall shape comprising a base configured to slide along the rail, and a rollers support connected to the base and comprising an axle forming a rollers support, The axle extends transversally with respect to the longitudinal direction of the component, on each side thereof, and a plurality of rollers for applying the substance being mounted on the transverse axle, one on each side of the component. The tool allows the substance to be applied effectively to the flange parts of the rail that is to be protected.

Abstract: A bite block device for use with intrabuccal instruments having a generally U-shaped central body. A lower vestibular rim extends from an outer periphery of a bottom surface of the generally U-shaped central body. A lower lingual rim extends from an inner periphery of the bottom surface of the generally U-shaped central body. An upper vestibular rim extends from an outer periphery of an upper surface of the generally U-shaped central body. An upper lingual rim extends from an inner periphery of the upper surface of the generally U-shaped central body. The upper surface, the upper vestibular rim, and the upper lingual rim are anteriorly discontinuous for a common length to form an intrabuccal instrument channel therethrough.
