Abstract

Abstract An apparatus for introducing materials into and removing materials from a hermetically seated vessel without destroying the hermetic integrity of the vessel comprising, a container defining a chamber therein which chamber communicates between the vessel and an environment having a dissimilar pressure, four valve means each operatively connected to the container and communicating between the interior and exterior thereof, and means for cyclically actuating said valve means so that the pressure within the chamber is equalized to the pressure within the vessel before the materials are transferred between the container and the vessel, and the pressure within the chamber is equalized to said dissimilar pressure before the materials are transferred between the container and said dissimilar pressure environment.
