The invention relates to a process for separating off maleic anhydride from a gas stream comprising maleic anhydride, in which a) the gas stream comprising maleic anhydride is brought into contact with a liquid absorbent phase comprising at least one high-boiling inert absorption medium for maleic anhydride and b) maleic anhydride is separated off from the resulting liquid absorbate phase by stripping with a hydrogen-comprising gas as stripping medium in a column, wherein the stripping medium is fed in at two points on the column which are at least one theoretical plate apart.

Sealed power cables (e.g. for underground or submarine use) are often equipped with a metal sheath. A problem with some such cables is that their insulation is subject to greater thermal expansion of the cable during use than the metal sheath is capable of following. According to the present invention the metal sheath (5) is longitudinally corrugated either when the metal sheath is manufactured or by pressing a metal sheet which is originally plane over resilient ribs disposed longitudinally on the cable.
摘要:
A device for assisting extraction of a material contained in a cartridge for preparation of a beverage has a wall which forms a hollowed enclosure which has an interior surface which defines a frustoconically shaped cavity for containing the cartridge. A rim intersects and extends laterally from the interior surface of the wall to form a peripheral rim base surface which intersects the wall for supporting a cartridge contained by the interior wall surface. A plurality of fins integral with the rim extend from the rim laterally, with respect to the interior wall surface, to converge and connect at an area which is centrally disposed, with respect to the interior wall surface and rim, and displaced at a distance away from a plane defined by the intersection of the interior wall and rim base surfaces so that the area of convergence is displaced away from a cartridge contained and supported by the wall and rim base surfaces. A finger is disposed centrally in the area of convergence of the fine and extends towards the plane.
