Abstract:
1. An apparatus for the addition of a compound or compound mixture to another comprising; a primary vessel adapted having at least one receptacle adapted to contain at least one primary substance; at least one secondary vessel each of which is adapted to contain at least one secondary substance, each secondary vessel being movably mounted within the primary vessel for movement vertically up and down within the primary vessel between a stored position and at least one mixing position, in the stored position a peripheral edge of each secondary vessel is above a level of the at least one primary substance, in each mixing position the peripheral edge of the secondary vessel is moved below the level of the receptacle containing the at least one primary substance, thereby permitting the at least one primary substance to overflow the peripheral edge into the secondary vessel with the at least one secondary substance; and at least one fluid conduit being provided through the primary vessel, the fluid conduit being adapted to accommodate an insertion or withdrawal of fluid from the primary vessel, thereby creating a pressure imbalance where the pressure above the at least one secondary vessel is greater than the pressure below the at least one secondary vessel and resulting in the at least one secondary vessel descending from the stored position to the at least one mixing position.
