Abstract: The invention relates to a flexible hose (10), which has a corrugated-profile inner hose (12) for conveying media along a longitudinal axis (18) and is surrounded, on an outer face (20), by a substantially flat covering (22), and is provided, on at least one of its two ends, with a connection piece. An electrical conductor (30) is situated radially between the inner hose and the covering, which conductor extends from one end to the other end of the inner hose and terminates in the connection piece to provide electrical contact. The electrical conductor is formed by a resilient flat-conductor assembly (32) which extends along the hose in an electrically insulated manner in parallel with the longitudinal axis and is held on the corrugated profile (34) of the inner hose at least by the covering. The invention also relates to a method for producing such a hose on a large scale.

Abstract: A bioreactor system for receiving a disposable bioreactor bag comprises a receiving container having a container wall which defines a receiving space in which the disposable bioreactor bag is received in an operating state of the bioreactor system. A stirring system projects at least partially into the receiving space and is designed and configured to stir a biomedium present in the disposable bioreactor bag in the operating state of the bioreactor system. At least one baffle, which makes the receiving space smaller and differs from the container wall, serves to reduce a laminar flow of the biomedium. A temperature control medium flows through at least part of the at least one baffle, said temperature control medium controlling the temperature of the baffle.

Abstract: The invention relates to a process for producing products having a specific geometry, in particular dental prostheses or auxiliary dental parts, comprising the steps of producing a plurality of products on the surface of a substrate plate by selective curing, in particular by selective sintering or melting, wherein the material is applied in successive layers, one or a plurality of predetermined regions are selectively cured by means of high-energy radiation and joined to one or a plurality of regions of the subjacent layer after each application of a layer, wherein the predetermined regions are predetermined according to a cross-sectional geometry of the product in the respective layer.
