Device for Registering the Occupancy of Tracks in Railway Traffic

03.09.2010
A very common method for determining the occupancy of a rail track are the so-called track circuits. This method involves applying a low voltage to a pair of rail tracks which are isolated from the rest of the network and monitoring whether the voltage is short-circuited by the wheels and axles of a passing train. Rust and dirt that may cover the rail surface over time can create significant problems. The present invention consists of a device that allows to break through the insulating surface and thus ensures reliable signalling. This is achieved by creating sparks between the carriage wheels and the rails. Advantages: no modifications required to the track network, can be implemented in cross border traffic, low costs, independent of the electricity network, etc.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
