ABSTRACT:
A tank is provided in which a lower solution is covered by an upper solution which is non-miscible with the lower solution. In the operating condition the apparatus automatically uncovers a small area of lower solution by raising the level of lower solution in that area and having the upper solution pass over a weir into a holding chamber. When the operating condition ceases, the solution automatically returns to the same levels as in the static condition.
