Machines for sorting objects having a series of carriages fixed at a given interval (P) to two drive belts configured to move along closed-loop paths in two parallel vertical planes are provided. Each path may include a top horizontal section and a bottom horizontal section joined together by two curved connecting end sections. Two end assemblies may be arranged at the curved end sections of the path. Each assembly may include crown gears which are configured to engage with the belts and a series of sliders which are configured to retain the carriages along a semicircular section close to the crown gears. The carriages are thus able to perform a rotary/translational movement along the end connecting sections and keep their support surface horizontally oriented.

Abrégé

The invention consists of a communication system that relays a satellite signal inside railway tunnels and relays the signals transmitted inside said tunnels towards the satellite, in such a way as to assure to vehicles transiting inside the tunnels a perfect transmission and reception quality even in the absence of satellite visibility. The system is based on a fixed terminal, for gallery illumination, connected to a fixed satellite station, and on a mobile terminal installed on the vehicle, connected to a mobile satellite terminal. The system automatically effects a switching action between satellite channel and radio channel in the tunnel, and vice versa, to assure the continuity of the vehicle-satellite connection. The system finds elective application for railway vehicles.
