Abstract: A device for the inductive transfer of electric energy from a stationary unit having a current supply device and a primary inductance to a vehicle that is adjacent the unit and has a secondary inductance. The vehicle has a secondary control element for adjusting the secondary power taken from the secondary inductance and comprises a control device enabling the withdrawn secondary power to be modified in steps. The stationary unit comprises a primary control element for adjusting the primary power and a first measuring device enabling an operational parameter, influenced by the secondary power, of the current supply device to be measured. The primary control element adjusts the primary power which can be injected in accordance with modifications of the operational parameter. The secondary power can be switched by the switching device and has in one of the steps, a value which is at least approximately zero.

Abstract: In a method for detecting an electrically conductive foreign body at a device for inductively transmitting electrical energy from a stationary unit having an electrical power supply unit and a primary inductor to a mobile unit having a secondary inductor and an electric load, electrical power is initially fed from the electrical power supply unit into the primary inductor and the feed-in is interrupted. The curve over time of the resulting decay of an electrical operating variable of the primary inductor is measured and at least one parameter of the measured curve is compared with a corresponding parameter of a reference curve in the event of an interruption of the power feed-in into the primary inductor without the presence of an electrically conductive foreign body. The comparison is used to determine whether an electrically conductive foreign body is present in the region of the magnetic field produced by the primary inductor.

Abstract: A device for the inductive transfer of electric energy from a stationary unit having a current supply device and a primary inductance connected thereto, to a vehicle which is adjacent to the stationary unit and has a secondary inductance. The vehicle has an emitter device for sending a data signal in the secondary inductance and the stationary unit includes a capturing device for capturing a data signal emitted by the primary inductance. The current supply device is activated by the capturing device in accordance with the content of the captured data signal for injecting the primary inductance. The emitting device includes a memory with a vehicle-specific code and the data signal which it produces contains the code. The capturing device includes a memory with an authorisation code and a comparison device such that the activation of the current supply device is triggered only if the comparison device identifies the authorisation code in the captured data signal.

Abstract: The invention relates to a connection element for running rails of a suspended track for receiving the running rails (2, 2?) and a securing device for securing the running rails (2, 2?) against being pulled out of the cavity (H, H?) and a running rail system having multiple running rails (2, 2?), which can be connected by connection elements (1; 11). The invention solves the problem of allowing simple and rapid tool-free mounting with a simultaneous secure connection of running rails of the running rail system in that the securing device of the connection element has at least one spring-elastic first connection claw (8; 12; 15), which projects diagonally in an insertion direction (E) of a first running rail (2) into the cavity (H) in the relaxed state, and/or by a running rail system having connection elements (1; 11) implemented in this way.
