Abstract
Abstract THIS DISCLOSURE RELATES TO AN APPARATUS AND METHOD WHEREBY LIQUID IS SUPPLIED TO A CONTAINER FROM A SUPPLY LINE ONLY WHEN A VAPOR SEAL IS FORMED BETWEEN THE SUPPLY LINE AND THE CONTAINER. FLOW OF LIQUID IS AUTOMATICALLY STOPPED WHEN THE LIQUID IN THE TANK REACHES A PREDETERMINED LEVEL, WHEN THE PRESSURE IN THE TANK EXCEEDS A PREDETERMINED VALUE, OR WHEN THE VAPOR SEAL IS BROKEN. VAPOR IS REMOVED FROM THE CONTAINER DURING FILLING THEREOF. WHEN FILLING CEASES OR THE SUPPLY LINE IS NO LONGER VAPOR SEALED TO THE CONTAINER, THE VAPOR REMOVAL LINE IS AUTOMATICALLY BLOCKED TO PREVENT ESCAPE OF VAPORS INTO THE ATMOSPHERE.
