摘要： In the process for the gentle degasification of coagulation-sensitive PVC latices in a confined space under reduced pressure and stirring at elevated temperatures with steam injection onto the latex surface, the improvement consisting essentially of conducting said degasification at a selected temperature from 50.degree. C to 80.degree. C at a pressure corresponding to the boiling pressure of water at the selected temperature, stirring said latex by an inclined stirrer whereby a rolling action of said latex in said confined space is effected and introducing said steam into the gas space above said latex but directed along the surface of the confined space.

摘要： This invention relates to a valve for the introduction of a gas into a liquid media comprising a housing, said housing having an exit port at one end, and exit port at the opposite end and a gas entrance port, said housing containing a movable hollow piston in a substantially water-tight connection with said housing, said movable hollow piston being sealed at each end and having gas distribution jets at one end, and a gas entrance port in communication with said housing gas entrance port when said hollow piston is extended, said hollow piston being in a substantially gas-tight connection with said housing when retracted, and means for extending and retracting said movable hollow piston in said housing, whereby when said hollow piston is extended, said gas distribution jets are exposed beyond said housing and a gas path is created from said gas entrance port to and through said gas distribution jets.
摘要翻译：本发明涉及一种用于将气体引入液体介质的阀，所述液体介质包括壳体，所述壳体在一端具有出口端口，在相对端具有出口端口和气体入口端口，所述壳体包含可移动中空活塞在与所述壳体基本上不透水的连接处，所述可移动中空活塞在每一端被密封并且在一端具有气体分配喷嘴，以及当所述中空活塞延伸时与所述壳体气体入口端口连通的气体入口，中空活塞在缩回时处于与所述壳体基本上气密的连接，以及用于在所述壳体中延伸和缩回所述可移动中空活塞的装置，由此当所述中空活塞延伸时，所述气体分配喷嘴暴露在所述外壳之外，并且气体从所述气体入口到所述气体分配射流产生通道。
