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: A process for producing polymers by the ionogenic polymerization of lactams is disclosed, wherein the lactam monomer, in the liquid state, mixed with a catalyst and promoter is introduced into a heated mold, which rapidly rotates about an axis outside the mold, via a conduit disposed co-axially with respect to the axis and via a feed channel which extends from the conduit at an angle to the axis and the polymerized, molded object is automatically removed from the mold in a radial direction due to centrifugal force.

Abstract: A process for the recovery of powdery homopolymers or copolymers of ethylene from a polymerization system is disclosed, wherein the corresponding monomers are subjected to polymerization conditions in a reactor and the resulting polymer, together with unconverted monomer, is discharged from the reactor and expanded to a lower pressure. At least part of this mixture is quenched by the addition of a cold gas, which gas is at least one of the polymerization monomers, to a temperature below the melting point of the polymer to solidify the polymer contained in such mixture as the form of a fine powder. Thereafter the powder is separated from the mixture and remaining unconverted monomer is recycled to the reactor. The process involves simpler equipment and reduced utility costs as compared to prior processes.

Abstract: In order to pulsate liquid in a column, the column is connected to both the suction side and the pressure side of a pump, via rotatable valve means which alternately connects the pressure side and the suction side of the pump to the column. The rotations of the valve and the pumping force and the flow capacity of the piping between the column and the pump primarily influence the amplitude and frequency of pulsations in the column. More than one valve may be connected to one column and more than one column can be connected to one valve. Preferred valve designs are disclosed, as are preferred fluid circuits incorporating surge tank means.

Abstract: A PROCESS FOR THE SEPARATION OF LOWER BOILING POINT LIQUIDS FROM THOSE OF A HIGH BOILING POINT, AND APPARATUS THEREFOR IS DISCLOSED. THE LIQUID MIXTURE IS SUPPLIED TO THE BASE OF THE EXTRACTOR AND PASSED UPWARDS UNDER CONTROLLED TEMPERATURE AND REDUCED PRESSURE IN THE VAPOR STATE THROUGH SEVERAL TUBES, WHOSE LENGTH IS FROM 15 TO 35 TIMES THEIR DIAMETER; THE VAPOR LEAVES THE TUBES AT A

VELOCITY APPROACHING THE VELOCITY OF SOUND IN THE VAPOR, AND IS SUBSEQUENTLY CONDENSED. THE LOWER BOILING LIQUID THUS RECOVERED IS OF HIGH PURITY, OFTEN REPRESENTING UP TO 90% OF THE TOTAL LOWER BOILING FRACTION OF THE MIXTURE ENTERING THE EVAPORATOR.

Abstract: In order to dislodge our bubbles from particles e.g. cut cylindrical fibers, as they enter a confined liquid body through a surface, a small portion of the liquid body near the surface is vibrated and the particles are funneled into the liquid body through the surface by means calculated to subject each particle to about the same amount of vibration. By preference this includes funneling the particles onto the central region of a submerged, perforated plate. The particles vibrate to the periphery of the plate and fall into the gap between the plate and the confining walls of the liquid body. In a counter current liquid extraction system, liquid may pass up through the plate perforations.
