Abstract: A compensating element having first and second modules is disclosed. A locking mechanism which can be switched between a first and a second operating state is provided. The first module is connected firmly to the second module in the first operating state. The first operating state defines a zero position between the first and the second module. The first and the second module are connected to one another in the second operating state by a spring mechanism in such a way that they are movable relative to one another. The compensating element has a midaxis, and the first and the second module are arranged at least partially next to one another in the direction of the midaxis. A measuring system is also disclosed with which the relative position between the first and the second module can be measured. The first or second module includes an externally visible luminous surface. A luminous state of the luminous surface is dependent on the relative position measured by the measuring system.

Abstract: Direct thermal decomposition of hydrocarbons into solid carbon and hydrogen is performed by a process and a device. The process comprises preheating a hydrocarbon gas stream to a temperature between 500° C. and 700° C. and injecting the pre-heated hydrocarbon gas stream into the reactor pool of a liquid metal reactor containing a liquid media; forming a multi-phase flow with a hydrocarbon gas comprising hydrogen and solid carbon at a temperature between 900° C. and 1200° C.; forming a carbon layer on the free surface of the liquid media made up of solid carbon particles which are then displaced into at least one carbon extraction system and at least one recipient for collecting them; and, at the same time, the gas comprising hydrogen leaves the reactor pool through a porous rigid section, being collected at a gas outlet collector from where the gas comprising hydrogen finally leaves the liquid metal reactor.
