Abstract: A corrugating apparatus comprises at least one device for producing an at least single-faced corrugated web transported along a transport direction, at least one cross-cutting device disposed downstream thereof along the transport direction for cutting the corrugated web and at least one discharge device for discharging waste pieces of the corrugated web perpendicular to the transport direction, wherein the discharge device comprises at least one controllably movable deflector element which is engageable with the waste pieces to be discharged.

Abstract: Photon emitter and data transmission device wherein a second resonator is arranged in a direction of emission of a radiation-emitting first resonator in such a way that a quantum dot contained in the second resonator can be excited by energy of radiation emitted by the first resonator. A control unit brings the excitation ground state of the quantum dot into resonance with a prescribed resonator mode of the second resonator.

Abstract: A shunt for a web, in particular a web of corrugated board, which is to be divided into several sectional webs in the conveying direction, comprises several shunting elements which are disposed side by side below the web of corrugated board and which are individually movable at least into a top position and a bottom position. Several compressed-air nozzles are provided, which are disposed above the shunting elements and directed towards the shunting elements and which are individually actuated by compressed air.
