Abstract: A method and device for controlling decentralized loads in an energy network, including at least two controllable loads, wherein the controllable loads are in particular energy consumers and/or energy storages and/or energy producers distributed over several buildings or building complexes. The loads are connected to a central energy supply by means of an energy supply line for providing power to the loads. In doing to, at least two controllable loads are provided. In the method, an inter-building load forecast is determined for several loads. In addition, an inter-building operational plan is created for at least two controllable loads on the basis of the inter-building load forecast. The controllable loads are driven on the basis of the inter-building operational plan and by means of the climate profiles of generated control data.

Abstract: A blood-taking device has a comparatively flexible inner tubule and an outer tubule. There is an annular gap between both tubules. The front end of the inner tubule is provided with an end wall pressing against the annular protrusion of an end wall of the outer tubule. In order to fix the inner and outer tubules with respect to each other, the edge of the inner tubule end wall has a locking profile interlocking with a counter profile of the outer tubule. During centrifugation the inwardly directed protrusion sinks into the soft material of the end wall of the inner tubule. Thus, liquid is prevented from entering the annular gap during centrifugation.
