Abstract: In an expansion system (11) of the heat transfer medium circuit (1) of a solar thermal power plant, comprising a plurality of expansion tanks (12a, 12b, 12c) and/or flooding tanks which are arranged in the heat transfer medium circuit (1), a solution is to be created which enables a technically simplified and constructionally less costly compensating or expansion system to be created. This is achieved by the expansion system (11) comprising a plurality of expansion tanks (12a, 12b, 12c) which are arranged at basically the same height level and are in fluid-conducting communication.

Abstract: The invention relates to a motor vehicle door hinge for the pivotal fitting of a vehicle door to a vehicle body, including a door member adapted to be fitted to the vehicle door and a pillar member adapted to be fitted to the vehicle body, these being pivotally interconnected. The invention further relates to a set of components for motor vehicle door hinges including a door member and a pillar member for the pivotal fitting of a vehicle door to a vehicle body. In order to provide a motor vehicle door hinge which can be manufactured particularly cost-effectively and furthermore to provide a set of components for the manufacture of a motor vehicle door hinge, the components of which permit the manufacture of at least two hinges which can be employed on a vehicle, provision is made in the case of the motor vehicle door hinge, that the pillar member and/or the door member are formed from at least two components, i.e. a base plate fittable on the vehicle side and a support arm fittable to the base plate.
