Abstract
A storage tank for liquids is provided with a vertically movable horizontal deck which separates a liquid above the deck from a liquid below the deck. The deck and tank have line and pulley mechanisms to prevent the deck from skewing or tilting during vertical displacement. The liquid above the deck can be the same or different than the liquid below the deck but generally they have different densities so that the deck can float at the interface between the liquids.
