Abstract: Method for facilitating operations for users of an industrial automation network with a plurality of automation devices, wherein work orders for the automation devices are managed in the automation network and are transmitted via a communications network, where a message service for exchanging messages between participants is operated with a list of participants that is prepopulated with virtual roles as participants such that the participants in the list of participants become variable participants, and where the users, the work orders or the automation devices are assigned to the virtual roles.

Abstract: A device for receiving liquids to which solids have been added, in particular for receiving liquid waste from nuclear power stations, includes a body having one open end and an inner chamber. A loss plate closes off the body and has an opening formed therein. A device for removing liquid from such a receiving device includes an inner chamber, a pipe communicating with the inner chamber for leading away liquid and a cover for bearing on the receiving device. The cover has an opening formed therein in the vicinity of the inner chamber, a side facing toward the receiving device and at least one seal at the side for bearing on the loss plate.

Abstract: A stopper rod in the form of an elongate molded body having a longitudinal bore has an attachment device for attaching the stopper rod to a lifting and lowering mechanism.

Abstract: Air containing entrained particulate matter is directed through a plurality of parallel, narrow, vertically oriented impactor slots of an inlet element toward an adjacently located, relatively large, dust impaction surface preferably covered with an adhesive material. The air flow turns over the impaction surface, leaving behind the relatively larger particles according to the human thoracic separation system and passes through two elongate exhaust apertures defining the outer bounds of the impaction collection surface to pass through divergent passages which slow down and distribute the air flow, with entrained smaller particles, over a fine filter element that separates the fine particles from the air. The elongate exhaust apertures defining the impaction collection surface are spaced apart by a distance greater than the lengths of elongate impactor slots in the inlet element and are oriented to be normal thereto.
