Abstract: A PROCESS AND APPARATUS IS DESCRIBED TO MINIMIZE THE DANGER OF AERIAL EXPOLSIONS WHICH OCCUR DURING THE HIGH PRESSURE, HIGH TEMPERATURE POLYMERIZATION OF ETHYLENIC MONOMERS. THE PROCESS INVOLVES RAPIDLY DISCHARGING AT LEAST 0.3 KG. OF WATER PER KG. OF REACTOR CONTENTS INTO THE SAFETY PASSAGEWAY AND OUTLET PIPE WITHIN 10 SECONDS FOLLOWING THE OPERATIVENESS OF SUCH SAFETY PASSAGEWAY BY THE OPENING OF VALVE MEANS WHEN AN EXCESSIVE PRESSURE LEVEL IS REACHED WITHIN THE REACTOR. VARIOUS APPARATUS STRUCTURES ARE ALSO DISCLOSED ADAPTED FOR PRACTICING THIS PROCESS WHEREIN THE WATER IS HELD IN RUPTURABLE BAGS OR, E.G., IS DISCHARGED INTO THE ESCAPING GAS STREAM THROUGH VALVE-OPERATED SPRAY MEANS, OR IN OTHER WAYS.

Abstract: For controlling the amplitude of pulsations of liquid in a column partly filled with the liquid and having a pulsing chamber which communicates with a gas cushion alternately compressed and expanded at a constant amplitude and frequency comprising: increasing and decreasing the amount of gas in the gas cushion. In the installation according to the invention the space behind the piston in the cylinder is connected with a buffer space, the volume of which is at least as large as that of the gas cushion, while the spaces in front of and behind the piston in the cylinder are connected by means providing a restricted communication.
