Title: Mobile residual-current device (residual-current circuit breaker)
Inventor: BECK MARTIN
IPC: H02H3/33
Filed: 1988-04-21
Abstract: The object exists of strengthening a residual-current device to such an extent that it remains switched on in the event of a mains voltage failure while at the same time monitoring the protective-earth conductor. The solution comprises the trip device 6 having a second winding 18 as well as a first winding 17. The second winding 18 is connected in parallel with a first voltage-dependent resistor 8 which is connected in the protective-earth conductor PE. In the event of a residual current, the residual current flowing through the first voltage-dependent resistor 8 produces a voltage drop which leads to tripping via the second winding 18 of the trip device 6. Residual-current devices trip as a function of the mains voltage. Residual-current devices have been used for a long time in r.c.d.-operated circuit breakers. It is not yet finally possible to assess the extent to which residual-current circuit breakers will become a real alternative to fault-current protection circuit breakers which trip independently of the mains voltage. <IMAGE>

Title: Erasable optical fluorescence and absorption data medium having good long-term stability
Inventor: LANGHALS HEINZ PROF DR
IPC: G11C13/04
Filed: 1989-01-24
Abstract: The preparation of dihydropyrrolopyrroldiones and their use of in optical storage systems is described. Particularly outstanding here is 2,6-bis(2'-methoxyphenyl)-2,5-dihydro-2,5-dimethylpyrrolo[3,4-c]pyrrol e-1,4-dione, which is converted from a weakly fluorescent, metastable modification into a highly fluorescent modification at 195 to 200@C. This conversion can be used for optical storage purposes, the particular advantage being that the fluorescence light can be detected simply and reliably. Further thermally initiated crystallisation allows the original state of a storage system of this type to be restored and the medium to be erased. It is then available for a further writing process.

Title: Flue gas purification system
Inventor: SPITZNAGEL GUENTHER DR
IPC: B01D53/86
Filed: 1989-03-23
Abstract: The flue gas (r) produced by a furnace plant (10) is fed to an emission device (32) via a flue gas desulphurisation plant (22) and, downstream of this, a DeNOx plant (30) with a catalyst. The DeNOx plant (30) preferably operates by the SCR principle with ammonia injection. According to the invention a heat transformer (36) is arranged as a device for reheating the flue gas (r) downstream of the flue gas desulphurisation plant (22). This heat transformer removes thermal energy from the flue gas (r) upstream of the flue gas desulphurisation plant (22) and from the flue gas (r) downstream of the DeNOx plant (30) and it passes thermal energy at a heat introduction point (23; 2, 3) into the flue gas (r) between the flue gas desulphurisation plant (22) and the DeNOx plant (30). As a result, the flue gas (r) fed to the DeNOx plant (30) has a temperature (T3) which is higher than the temperature (T2) of the flue gas (r) given off by the flue gas desulphurisation plant (22). This temperature (T3) is preferably also higher than the temperature (T1) of the flue gas (r) fed to the flue gas desulphurisation plant (22). <IMAGE>
