Abstract: The present invention describes a nuclear reactor with a loop for liquid nuclear fuel, which, contrary to similar systems like the Molten-Salt Reactor of the Generation-IV canon, does not use the fuel loop for the heat transport at the same time. Instead, cooling is provided by an additional coolant loop, which is intensively coupled to the nuclear fuel duct for heat transport. That way, the advantages of liquid fuel can be utilized while optimizing the coolant loop performance, so the complexity of safety systems can be reduced significantly. This reactor design further includes an optimized neutron economy and is able to deactivate long-lived fission products generated by its own, so only short-lived radiotoxic waste has to be stored. With the neutron surplus it is also possible to deactivate long-lived radiotoxic waste from used fuel of today's light water reactors or to produce medical radioisotopes.

Abstract: The invention is directed to an elevator system for the vertical transport of payloads in an aircraft.

Abstract: An elevator system for the vertical transport of payloads in an aircraft is disclosed. The arrangement of the elevator system provides for the vertical transport of payloads in an aircraft which permits low-noise, reliably operating conveying between different levels of the aircraft and reliable stopping in the loading and unloading positions. The arrangement is characterized by low maintenance and low weight, in that the drive system has at least one closed belt for driving and for receiving the load of the elevator cabin, which belt is guided at either end of the mast on deflection rolls and has, between the deflection rolls, at least one freely accessible belt portion oriented parallel to the mast for fastening the elevator cabin and for the movement of the elevator cabin along the mast. The deflection rolls and the belt are provided with teeth which are adapted to one another and the belt is pretensioned in a defined manner.
