Abstract: Vanes positioned immediately adjacent the swept area of a moving friction brake rotor induce a flow of air over the rotor by displacing the boundary layer of gases from the rotor surface and conducting such layer along the intercepting surface of the vane, and thus inducing a flow of cooler air over the rotor. Under heavy braking, friction pad particles and substantial quantities of thermal energy in the superheated gases of the boundary layer are removed by the vanes.

Abstract: A bushing formed of an outer body and an inner sleeve member adapted to rotate within the outer body, the outer body having a bore adapted to rotatably receive the inner sleeve member such bore being eccentric, i.e. offset and/or skewed, relative to the axis around which the outer surface of the outer body is generated, and the inner end member having a usually tapered bore similarly eccentric to the axis of the outer surface of the inner sleeve member such that the inner member may be rotated relative to the outer body with the eccentricity of the bore of the outer body and the bore of the inner member either being additive or cancelling such that the effective eccentricity of the inner bore may be adjusted to the outer surface of the outer body to provide, for instance, caster and camber compensating bushings for vehicles, and other similar eccentric bushing uses.
