Automatic mixing of liquid organic compounds

摘要

A method of automatically mixing predetermined quantities of liquid organic compound and liquid propellant is disclosed. A metering cylinder is filled from a storage reservoir of a liquid organic compound and then disconnected from the reservoir. Then one end of the metering cylinder is connected to a source of liquid propellant, the other end is connected to a mixing vessel, and vapour pressure of the liquid propellant is utilized to force all of the liquid organic compound into the mixing vessel, together with a predetermined volume of liquid propellant.
