Abstract: A bearing journal projects from an end of a material web wound into a roll. The bearing journal has a bearing surface formed as a rotating surface, a fitting surface not formed as a rotating surface, and an axial guide surface. A dispensing system includes a dispenser that is adapted to receive the roll of web material and to cooperate with the bearing journal.

Abstract: A method of spraying an air-improving substance in a room is provided. In particular, persons moving in the room are detected, and a spraying operation is performed while taking into account the detected movement.

Abstract: A container is formed from a flexible material web of weldable plastic. A reinforcing element is attached on the exterior of a wall of the container. The, said element being located on the exterior of the container. The container may be formed by drawing a flat material web of weldable plastic material over a core tube and welding a longitudinal seam for closing the flat material web to form a tube. Then a reinforcing element is welded on an exterior of the tube while employing the core tube as an internal cooperating support. The tube is divided and separated along transverse seams into cut-off containers to form the containers. A dispensing system for flowable products includes at least one closed container, as described, and a dispenser provided with a container receiving device for holding the container without closure. The container is formed with sliding guide and a displaceable closure, which is preferably opened when the container is placed on the receiving device, and a first coding element.

Abstract: A paper dispenser has a dispensing opening for paper and also a first roll, which is located in a dispensing position, and a guide path, which leads into the dispensing position and contains a storage position for a reserve roll. The dispensing opening is of a size which, once the first roll has been used up, allows manual access to the paper of the reserve roll, while the reserve roll is still in the storage position.

Abstract: In the production of diluted solutions in different concentrations, in each case an amount of a concentrate and an amount of a diluent are mixed. The ratio of the two amounts is never changed. The different concentrations of the diluted solutions result from concentrates of different concentrations that are used.

Abstract: A brush head for one-time use is equipped with a bundle of bristles that is fashioned from a flat strip of material that disintegrates in water. The strip is formed with incisions defining therebetween the bristles of the brush. Material bridges connect the bristles to one another and they break up upon being wetted before said bristles disintegrate.

Abstract: A discharge valve for a container (1) containing a flowable medium, having a movable valve part (10) which, in a rest position, keeps an outlet closed, has at least two open positions with different outlet cross sections.

Abstract: A brush head for one-time use is equipped with a bundle of bristles (11) that is fashioned from flat strip of material (1).

Abstract: The invention relates to a device for dispensing of paper sections, which has a rotatable roller (1) provided with a slot (4), and a blade (5) arranged in the roller (1). The blade (5) is arranged on a carrier (7) pivotable inside the roller (1) and can be moved outwardly through the slot (4) to separate each paper section respectively across one part of the roller turn. A four-bar linkage is used to guide the blade (5) which is either articulated to the pivotable carrier (7) and displaceable in a slide guide (8) or articulated to two carriers (7, 9) tiltable about parallel axes (11, 12).

Abstract: A time switch has a resetting, movable switching member on which there is provided a suction cup which can be pressed against a counterpart body. The cross-section of an air inlet opening (9) into the reduced-pressure space between the counterpart body and the suction cup when pressed against the counterpart body determines the switching time and is preferably adjustable. A venting opening with which a removable closure element is associated additionally opens into the reduced-pressure space.
