Abstract:
To ascertain the fill level of vessels (10), mechanical vibrations are produced in a vessel wall (30) and the vibration pattern is analysed. The vibration is produced in a vessel wall (30) which is contacted by the contents to an extent which varies depending on the fill level, and the vibration pattern is then evaluated to discover to what extent the vessel wall (30) is contacted on the inside by the contents. For this, the decay time, the frequency, the intensity and/or the time integral of the intensity can be evaluated or the site of the maximum intensity of the mechanical vibrations in the vessel wall can be ascertained.
Abstract:
Rotationally symmetrical containers (10) are transported under backup pressure on a conveying surface (12) limited laterally by railings (14). For rotating the containers (10) at a predetermined site along the conveying surface (12), one of two consecutive containers (10) is arranged stable against one railing (14) and the other stable against the other railing (14) in the direction of conveyance after the site at which the containers are to rotate.

An inspection station for inspecting the sidewalls of the containers (10) is provided that has a radiation source (18) arranged adjacent to the conveying surface (12) and a detection device (20) arranged on the opposite side.
Abstract:
In order to determine parameters of closed containers, primary mechanical oscillations are excited in a container wall. The secondary oscillations which are excited in the container by the primary mechanical oscillations of the container wall and which occur within the space between a closure and the liquid are picked up and analyzed, the parameters being determined from the ascertained frequency characteristic of these oscillations. In addition, the primary oscillations of the closure can also be picked up and analyzed, the internal pressure prevailing in the container being determined from the frequency of these primary oscillations. The frequencies of the primary and secondary oscillations can be determined by analysis of the frequency spectrum. The secondary oscillations can be picked up separately from the primary oscillations in that only those oscillations are picked up which occur within a time measurement window within which the primary oscillations have already decayed.

Abstract:
The apparatus serves to apply a label to a container through the use of an electrooptical device that senses the orientation of the container and sends the signal to a control device that directs the rotation of the containers to a target orientation that allows the label to be applied at a predetermined position on the container. A method for applying a label to a container is also disclosed.
Abstract:
The device for separating individual or a plurality of rotationally symmetric containers (11) from a stream of rotationally symmetric containers (10) conveyed under backup pressure comprises a first conveyor path (12) for the stream of containers (10) and a second conveyor path (18) for removal of the separated containers (11), the second conveyor path (18) branching off at a separation point (16) from the first conveyor path (12). The first conveyor path (12) bends at the separation point (16) at an acute angle. A dividing wedge (20) is disposed between the first and the second conveyor (12, 18). A first deflection slide (22) is disposed at the separation point (16) next to the first conveyor path (12) at the side of the branching of the second conveyor path (18) and is extensible towards the tip of the dividing wedge (20), and a second deflection slide (24) is disposed at the separation point (16) next to the first conveyor path (12) at the side of the bend of the first conveyor path (12) and is extensible towards the tip of the dividing wedge (20).
Abstract:
A conveyor for moving items may move synchronously with a number of diversion segments for a section and the diversion segments can be individually extended and retracted across the direction of transport, in order to push an item (10) off the conveyor (12). The diversion segments (22) are guided individually in extendable and retractable manner side by side in a carriage (18) in the direction of transport and the carriage (18) can be moved to and fro in the direction of transport. The carriage (18) is generally controlled such that it runs for a section roughly synchronously with the conveyor (12), the length of the section along which the carriage (18) plus the minimum interval between the items. A rail (26) that can be moved across the direction of transport can be provided, with which the diversion segments (22) can optionally be individually coupled.
Abstract:
Containers are conveyed past an apparatus for inspecting the bottom of the containers for contamination, flaws and foreign bodies. To that end, the containers are fed into the inspection apparatus by a first conveyor, and guided out of the inspection apparatus on a second conveyor, in which a gap is left between the first and second conveyors, within which the containers are not supported, at least not over the whole of their under surface. The containers on the first conveyor, within the gap and on the second conveyor are guided by side guidance apparatus and are conveyed under dynamic pressure, at least within the gap.
