Abstract: A continuous process for making polyolefines are disclosed. The process involves a membrane-assisted separation of non-reacted olefins downstream a polymerisation reactor and enables economical production of polyolefines from non-polymer grade olefin monomers. Uses of membranes adapted to such processes are also disclosed. And, further disclosed are membranes, membrane modules, and separation units adapted to such process as well as polymerisation plants comprising such membrane separation units.

Abstract: The disclosure relates to a drinking device that comprises two separate compartments, a first compartment for holding a flavored beverage or a flavoring agent for reconstituting the flavored beverage and a second compartment for holding an unflavored or weakly favored beverage, and a switching mechanism that allows for the sequential consumption of beverage from the first and the second compartment such that a subject ingests, in the course of each drinking event, first a volume of the flavored beverage and thereafter a volume of the unflavored or weakly favored beverage. Drinking from the device conveys to the subject a sensory experience that is similar to that produced by a typical uniformly flavored beverage even though it only consumed a fraction of the amount of flavoring agent that it would have consumed from drinking an equivalent volume of the uniformly flavored beverage.
