Title: Process and apparatus for reducing the nitrogen oxide content in the exhaust gases of a cement rotary kiln
Inventor: GARDEIK HANS OTTO DR ING
IPC: B01D53/56
Filed: 1984-07-17
Abstract: To reduce the nitrogen oxide content in the exhaust gases of a cement rotary kiln having an upstream preheater, a part-stream of the gas mixture leaving the rotary tube (1) is reductively treated by heating and then mixed with the oxygen-containing other part-stream and conducted under oxidising conditions for complete combustion of carbon monoxide. In a cement rotary kiln having a cyclone preheater (6) and calciner (3), a part-stream of the gas mixture leaving the rotary tube (1) is passed through the zone (26) of the calciner (3) operated under reducing conditions and, after mixing with the other part-stream, is passed through the zone (29) of the calciner (3) operated under oxidising conditions. If a grate preheater is connected upstream of the rotary kiln, a part-stream of the gas mixture leaving the rotary tube is heated under reductive conditions and passed into the hot chamber of the grate preheater and mixed there with the other part-stream. <IMAGE>

Patent DE-3511921-A1 (DE)
Title: Magnetic-current generator
Inventor: JAKUSCH PETER
IPC: H02K53/00
Filed: 1985-04-01
Abstract: Using the magnetic-current generator, the efficiency of production of energy (current) can be considerably increased. The stator (6) (circular tube housing) consists of non-magnetic material. A plurality of radial permanent magnets (2) having an iron ring (3), screen plates (7) and windings (8) are pushed on to the stator (6) and anchored. The rotor (1) consists of a plurality of round-rod permanent magnets (1) forming a composite (1) (1) (1) and having a radius which corresponds to the stator. Since there is only one moving part (rotor) (1) and it is accommodated in the totally dust-proof stator (6) (circular tube housing), a long life can be assumed, even without servicing. The construction of the magnetic-current generator is very simple and can therefore be constructed in very different sizes. Installation is possible, for example, in a pocket watch, in people, in cars, domestically and in factories. As a large generator, the magnetic-current generator can be installed completely under the earth's surface without interfering with the natural view, since it represents virtually a flat disc. The power consumption is very low. The magnetic forces of the rotor (1) and those of the radial permanent magnets (2) are weakened by magnetic depolarisation (magnetic forces in the same direction, repulsion). By remagnetisation or replacement of the permanent magnets, the driving energy can be supplied again. The energy contained in one magnetisation may [last] for an operating time of several months, possibly years ... Original abstract incomplete. <IMAGE>
