Abstract: A removal system (1) with an extraction head (2) that may be placed onto an opening of a bottle (3)), wherein the extraction head (2) has a closing means for closing the opening of the bottle (3). In the extraction head (2), a tube (5) is mounted such that when the extraction head (2) is placed onto the opening, the tube (5) projects into the bottle (3) and fluid (4) may be removed from the bottle (3) via the tube (5). An actuation mechanism is provided, by means of which the mounting of the tube (5) in the extraction head (2) may be released.

Abstract: A withdrawal system (1) for a container (2) and comprises an immersion pipe (4) mounted on and projecting into the container (2) as well as a withdrawal head (5) that is attachable to the immersion pipe (4) by means of a rotary connection. The withdrawal head (5) attached to the immersion pipe (4) is secured by means of a mechanical locking unit.

Abstract: The invention relates to a withdrawal system (1) for filling and emptying containers and involves a container closure (2) that is inserted into a container opening of a container seating a bung head. An immersion pipe (4) connected to the bung head has an extraction connector element connected to the immersion pipe (4) or the bung head. A transponder generating a transponder signal is provided; a monitoring signal is generated in dependence upon the transponder signal that indicates whether there is a permissible connection of the extraction connector element to the container.

Abstract: The invention relates to a removal system for a portable container and comprises an immersion pipe that is mounted in a bung unit that is held in an opening of the container. Furthermore, the removal system includes an extraction head that can be fastened to the immersion pipe. A switch that generates a switching signal whose switching states indicate whether the extraction head is fastened in a target position on the immersion pipe or not is provided in or on the extraction head.

Abstract: The invention relates to a closure stopper for containers of liquids, which is configured as a one-piece plastic part. A central degasifying vent (6) is covered on the inside by a bonded-fibre filter (7). An expansion-resistant wall (5) projects from the inner side (1a) of a ceiling wall (1) that surrounds the degasifying vent (6) on all sides at a distance. The bonded-fibre filter (7) is fixed to a protrusion (8) that is melted onto base of the expansion-resistant wall (5).

Abstract: In a hose coupling with a coupling sleeve and a coupling nipple and a valve insert (9) provided therein, the valve spring, the holding element and the valve seat of the valve insert are designed as a one-piece component, and the valve spring (11) has a cavity (21) which is closeable.

Abstract: A pump has a rotor-carrying pump shaft rotatably supported within an internal pipe by a plurality of spaced bearings. A lowermost bearing is located in the vicinity of the rotor near the end of the internal pipe. Adjacent to the lowermost bearing is a seal provided in a reduced-pressure chamber within the internal pipe, the chamber being closed off at the lower end by the bearing juxtaposed to the rotor. The reduced-pressure chamber is connected to an outlet opening in an external pipe which surrounds the internal pipe and is spaced therefrom to provide a transport channel for effluent material being moved by the rotating rotor.
