ABSTRACT:
A float controlled mechanism designed to allow the storage in and removal of variable amounts of gaseous reaction product from a reaction vessel of fixed size at a fixed pressure. The control mechanism uses a float to sense the level of the liquid in the vessel and maintain a fixed head of liquid above this level thereby maintaining a fixed pressure in the sealed reaction vessel.
