摘要： A method for the separate discharge of the individual phase streams of a multiple component flow comprising a high viscosity slow flowing liquid or suspension and a gas flowing at at least 100 times faster with the volumetric ratio of the gas to the liquid being greater than 1:1. The multicomponent flow is transversely fed through an inlet and directly into a rotating helical channel for conveying liquid in one direction. The channel has a liquid outlet spaced from the inlet in the one direction and a gas outlet spaced from the inlet in the opposite direction. A gas shut-off is formed between the inlet and the liquid outlet so as to effect the discharge of gas through the gas outlet in the opposite direction during the conveying of the liquid by the helical channel to the liquid outlet in the one direction.

摘要： By treating aromatic polycarbonates, aromatic polyester carbonates and aromatic and/or araliphatic polyesters in the molten state with super-critical gases or gas mixtures under pressure, the melt viscosity of these polymers is considerably lowered so that basic chemical operations which proceed only incompletely under the usual conditions can be carried out on these thermoplasts.

摘要： A twin-screw machine used for treatment of plastics in which the screw shafts are fitted with eccentrically arranged kneading discs, the clearance .delta. between the kneading discs and the inner wall of the machine housing being greater than the constant clearance s between the particular adjacent kneading discs, and the eccentricity e, which is in each case of like orientation, between the axis of rotation and the central point of the kneading disc being greater than zero and less than half the absolute value of the difference between the housing and disc diameters minus the clearance s.
