Abstract
A disc is rotatably mounted in a position to be partially exposed to, or immersed in, a liquid. Slow rotation of the disc causes liquid adhering to the disc to move upward into a position where wipers remove most of the adhering film, and divert it into a drainage trough or collector. In the simplest form of the invention, the disc is of magnetic-responsive material, and the wipers are flexible strips having permanent magnetism.
