Abstract: An unwind station for a packaging machine may be configured to form wrappers having different sizes from a web of packaging material and supply the wrapper to a wrapping station. The unwind station may include a base configured to support the web of packaging material and a carriage configured to selectively slide in a longitudinal direction on the base. A rotating blade can be configured to periodically score the web to form a break line extending between lateral sides of the web. A first conveyor arm and a second conveyor arm may project longitudinally outward from the carriage. The first conveyor arm and the second conveyor arm can each include a low-speed conveyor configured to transport the web to a high-speed conveyor. The high-speed conveyor is configured to separate the wrapper from the web as the break line passes a shear point between the low-speed conveyors and the high-speed conveyors.

Abstract: The invention relates to a gas sensor having a mechanical microresonator, which has an excitation apparatus for optically exciting a mechanical oscillation of the microresonator as well as a reading apparatus for detecting the oscillation of the microresonator, wherein the reading apparatus comprises a waveguide which is implemented together with the microresonator on a dielectric or semiconducting substrate and is intended to optically read the oscillation of the microresonator, and wherein the excitation apparatus has an optical waveguide which is implemented on the same substrate and optically connects an excitation light source to the immediate surroundings of the microresonator. The invention also relates to a use of such a sensor to analyse a gas composition.

Abstract: Method and device for inactivating a microbiologically contaminated mass containing solid particles. The method includes mixing the mass containing solid particles with a gelatinizing agent, transporting the mixed mass of solid particles and gelatinizing agent through a shaping device structured so that the mixed mass, at least in one area, is shaped to form a lamellar volume with a layer thickness of between 1 mm and 3 mm, and impinging the formed lamellar volume of the mixed mass with accelerated electrons.

Abstract: A modular packaging system includes a base system configured to manipulate a product and configured to receive at least one of a group of packaging modules, wherein the base system is used with a variety of packaging modules depending on a desired packaged output. The system also includes a first packaging module selectively coupled to the base system, the packaging module having a first member coupled to the packaging module, the member configured to manipulate an object. The system may also include a second packaging module selectively coupled to the base system, the second packaging module having a lifting device coupled to the second packaging module, the lifting device configured to manipulate an object.

Abstract: A curtain consists of a web of temperature resistant material that forms a web surface and that may be unwound from a coil that is arranged on a coil core. The curtain web has lateral edge regions on either side of the web so as to be separated by the curtain web's width and upper and lower end edge region. The curtain web includes a first outer web layer, and inner layer of fibrous material that extends over a predetermined length and that forms two opposed surfaces, one of which is adjacent to the first outer web layer. The curtain web also includes a second outer layer that is adjacent to the other surface of the inner layer. The curtain arrangement further includes a supply for a liquid fire retardant that extends with in the region of the upper end edge region and over the width of the curtain so as to supply the liquid to the fibrous material.
