Abstract
Pressurized cylinders are rapidly filled with acetylene gas and solvent in a staged process that is closely monitored by a control unit to assure that filling progresses with all critical variables maintained within safe bounds. An operator performs certain preliminary cylinder hookup tasks as monitored and prompted by the control unit. The control unit conducts the actual filling of the cylinder, carrying out this procedure in distinct filling stages with alternate injections of solvent and gas into the cylinder. The improved system enhances the safety and efficiency with which acetylene cylinders are filled.
