Abstract: A device for laminating a substrate with a thermoplastic coating material has an IR heating device for melting a surface of the coating material, an opposite cooling apparatus which actively cools the opposite surface of the coating material, and at least one press-roller assembly, which presses together the substrate web and the coating material to produce a hot-melt adhesive bond. In order to prevent any irregularities in the finished product, the cooling apparatus is designed as a rotatably driven cooling roller, over the circumference of which the following are arranged in succession: a feed apparatus for the thermoplastic coating material, one or more IR radiant heaters for heating the surface of the thermoplastic coating material resting on the cooling roller, a feed apparatus for the substrate web, one or more press rollers for pressing the substrate web against the coating material, and a removal apparatus for the laminated product.

Abstract: A centrifuge for a semiconductor wafer has a centrifuge plate for holding a semiconductor wafer, has a drive for setting the centrifuge plate in rotation, and has a device for supplying a medium to a front side and a rear side of the semiconductor wafer. The centrifuge has a housing which separates a centrifuging area and the semiconductor wafer from the environment, and a device for generating a laminar gas flow in the housing. A method for centrifuging a semiconductor wafer has the semiconductor wafer being centrifuged in a laminar gas flow.

Abstract: The present invention relates to a process for drying protein crystals starting from an aqueous protein crystal suspension, which comprises drying the protein crystal suspension in a centrifugal dryer, where the protein crystals, after they have been filtered off from the protein crystal suspension, are brought into contact with a drying medium which consists of a mixture of water and a nonaqueous solvent which is miscible with water in any ratio and which has a lower vapor pressure than water. In the process, a drying gas which has been moistened with water is advantageously used. The protein crystal suspension is advantageously converted into a fluidized bed for the purpose of drying.
