Abstract: Various embodiments include a sealed laminated metal structure. This laminated metal structure has a metal layer, where the metal layer has a first surface and an opposite second surface. A material is laminated on each of the first and second surfaces of the metal layer. In some cases, the laminated metal structure is removed from a larger laminated sheet of metal. The laminated metal structure is subjected to alternating current electrolytic deburring and cleaning to remove any burrs along the perimeter edge. After deburring and cleaning, a sealer, which is a phosphate compound, is deposited on the perimeter edge of the laminated metal structure where the metal is exposed using alternating current.

Abstract: Engaging inclined surfaces of an inner ring and an outer ring create wedge action inducing an inward radial force as the rings are forced together longitudinally, holding the adjustor on a rotating body. An inner total arcuate length of each ring is smaller than an outer total arcuate length of a respective target body (inner ring for outer ring, rotating body for inner ring). Arcuate segments of each ring can have inner surfaces with radii of curvature equal to or smaller than that of the target body outer surface, and with a total arcuate length smaller than the circumference of the target body's outer surface.
