Abstract: Container treatment system for containers, with a transport device for transporting the containers, at least one treatment assembly for treating the containers at a first transport section of the transport device, at least one robot unit for channeling individual treated containers out and/or in at a second transport section of the transport device downstream of the first transport section, and with at least one inspection device for inspecting the individual treated containers, where the second transport section is configured to transport a container flow that is widened as compared to the first transport section so that the individual treated containers can be transported there at reduced speed and/or with reduced dynamic pressure when channeled out and/or in.

Abstract: A method for evaluating plastic preforms, wherein said plastic preforms are intended to be heated by a heating device and then expanded by a forming device by application of a flowable medium to form plastic containers, wherein the plastic preforms extending in a longitudinal direction and having several portions in the longitudinal direction, wherein the several portions having at least one threaded portion, a main body portion and a bottom portion, wherein at least the main body portion and the bottom portion being inspected, wherein values characteristic of a material quality of the plastic preforms are output, wherein the values being assigned to different portions and/or at least one property of the container to be produced being taken into account in the evaluation of the characteristic values.

Abstract: Apparatus for inspecting containers, having a transport device which transports the containers along a predetermined transport path, and having an inspection device for inspecting the containers, wherein this inspection device has an image recording device which is configured for recording a spatially resolved image of a bottom of the container. The apparatus includes an image evaluation device which is configured for evaluating the image recorded up by the image recording device, wherein this image evaluation device enables a distinction between images of those containers which have foreign bodies in their interior and those containers which have foreign bodies on an outer surface of the bottom.

Abstract: Disclosed is a method for heating plastic preforms, wherein the plastic preforms are transported along a predetermined transport path and are heated during this transport by applying electromagnetic radiation, wherein an absorption and/or transmission of the plastic preforms is determined for radiation in an infrared wavelength range, wherein an absorption and/or transmission of the plastic preforms and/or of the plastic containers produced from these plastic preforms is determined for radiation in a visible wavelength range.

Abstract: A method for inspecting a device for forming plastic preforms into plastic containers, the device having a transport unit, at which a plurality of forming stations for forming plastic preforms into plastic containers is arranged, and an inspection unit that is arranged after the forming stations in a transport direction of the plastic containers and that determines a wall thickness of these plastic containers in at least one region of the plastic containers produced, includes the following steps: introducing at least one test container that has a predetermined and/or known wall thickness a least in sections, and determining a first wall thickness in at least one area of the container by the inspection unit.

Abstract: A device for drying containers, especially bottles, includes a substantially closed drying chamber, with an inlet opening, an outlet opening, and a transport system for the containers. The containers are transported through the drying chamber standing in an upright position. An air supply opening supplies drying air. At least one cleaning device chemically and or mechanically cleans the interior of the drying chamber, whereby a cleanser and/or a disinfectant can be injected into the interior of the drying chamber, distributed inside the drying chamber and removed from the drying chamber through the cleaning device. A method for cleaning a device for drying containers, whereby the at least one cleanser and/or disinfectant is injected into the interior of the drying chamber, distributed inside the drying chamber and removed from the drying chamber through the cleaning device.

Abstract: An openable motor vehicle roof including a closing element adapted for movement into a position that closes or at least partially clears an opening in a fixed roof skin of the motor vehicle, and a cover element adapted to be positioned underneath the roof opening for movement into a position that conceals or at least partially clears the closing element or the roof opening with respect to an interior area of the motor vehicle. At least one drive mechanism is provided for selectively and adjustably moving the closing element and the closing mechanism. Also provided is a controller for controlling the drive mechanism, the controller adapted to control the drive mechanism such that movement of the closing element into a closed position is not initiated until the cover element is moved at least into a position which covers an area of the roof opening that is not covered by the closing mechanism.

Abstract: A circuit for the supplying power to at least three electric servomotors, such as servomotors used for an openable motor vehicle roof, each electric servomotor having a first terminal and a second terminal.
