DEFINITION

Classification: 4/368

With outlet siphon:

(under subclass 353) Subject matter including a flow passage comprising two branches or legs of unequal length by which a liquid can be transferred to a lower level over an intermediate elevation by the pressure of the atmosphere in forcing the liquid up the shorter branch or leg immersed in it while the excess of weight of the liquid in the longer branch or leg causes a continuous flow.
