Title: Liquid metal cooled reactor drives gas turbines - in secondary circuit of dissociating gas giving high efficiency
Inventor: BARLEON LEOPOLD DIPL ING DR
IPC: G21D5/12
Filed: 1974-07-11
Abstract: A method of operating a liquid-metal-cooled nuclear power plant with a gas secondary circuit esp. for driving turbines consists of using, for this gas, one or more chemical compounds which dissociate when heated, recombine when cooled and in their initial form are associating. Preferred secondary coolants are N2O4, and metal halides, esp. Al2, Cl6, Al2, Br6 and Hg2Cl4. The method may also be used for systems with several liquid metal circuits coupled through heat exchangers. Esp. for a liquid metal-cooled fast breeder reactor. Higher thermal efficiencies are possible in the gas turbine cycle using dissociating gases than with a steam cycle. The high power demand for gas compression found in an inert gas cycle does not arise. Leakages, resulting in reactin between sodium and gas, esp. N2O4, lead to the formation of nitrate, and nitrites, which are liquid at operating temperature. There is no explosive effect, as with sodium and water. N2O4 is not activated by neutrons or radiolysed.

Title: Chopped rubbish sifted mainly by air currents - produces five categories one of size and four of weight
Inventor: ROTHERT HORST
IPC: B07B4/08
Filed: 1975-10-29
Abstract: The main component is a wheel with vanes all round its circumference. The vanes are all the same few degrees askew from the radial direction. This wheel not only carries the rubbish mechanically along part of its path, but is also the source of the two air currents that do most of the separation, and is effective even with damp, sticky material. The rubbish first passes between chopping knives, then over a vibrating sieve (where sand, ashes, etc. fall out) and on to the circumference of the wheel. Here it is met by a vertical updraught, which passes outwards through the vanes and lifts the lighter material into an inverted U pipe; the second limb of the inverted U has a central partition which divides this light fraction into two. The heavier fraction continues and at the point where it starts to fall freely away from the wheel, a horizontal draught comes out between the vanes, to half this fraction, thus making five fractions in all.
