Abstract: Methods and apparatuses for coating a flexible substrate are provided. The flexible substrate is guided over a process roller. The flexible substrate has a first protective film, which is removed from the flexible substrate before the flexible substrate reaches a coating zone of a coating device located opposite the process roller. The first protective film is removed from the flexible substrate after the flexible substrate has formed a mechanical contact with the surface of the process roller. A second protective film is applied to the coated side of the flexible substrate after the flexible substrate has left the coating zone of the coating device and before the mechanical contact between the process roller and the flexible substrate is ended.

Abstract: A crane installation, especially a container crane, for moving a load, especially a container, includes a first stored-programmable control unit which, if required, receives signals resulting in a safety-related control command to one or several electric or electro-mechanical operational elements, and a second stored-programmable control unit which is configured in such a way that it can at least partially monitor the control operation of the first control unit on the basis of safety-related signals transmitted to the second control unit. If the safety-related control command of the first control unit is improper, the second control unit is able to issue its own control command to an operating element.

Abstract: In a valve drive for a piston internal combustion engine with a first rocker lever which is in operative contact with at least a first cylinder valve, wherein a cam structure including a first cam and at least one additional cam is in active contact with a second rocker lever, which can be placed in force transmission contact with the first rocker lever by an actuator element for transferring the pivot motion generated by the first and second cams selectively from the second rocker lever to the first rocker lever and at a rate depending on an idling angle determined by the actuator element.

Abstract: In a method for operating a container crane of a type having a movable trolley with a height-adjustable container spreader for loading containers to or unloading containers from a transport vehicle, in particular a ship obstacle data or target positions, or both, are acquired before or during loading of the containers on the transport vehicle. The trolley is moved at least in semi-automatic operation either with a received container or without a received container relative to the transport vehicle and positioned relative to a position selected on the transport vehicle in response the acquired data.

Abstract: The invention provides highly concentrated aqueous solutions of a first amphoteric surfactant, especially of betaines or amine oxides, which comprise one or more further amphoteric cosurfactants which have a different structure from the first amphoteric surfactant, in amounts by weight of from 0.01 % to 10%, preferably from 0.1% to 5%, more preferably from 0.5% to 3%, based on the highly concentrated aqueous solution.
