Patent DE-4109429-A1 (DE)
Inventor: PFALZGRAF BERNHARD DIPL ING
IPC: F02P5/153
Filed: 1991-03-22
Abstract: The invention discloses automatic adaptation of spark timing in dynamic processes for a spark-ignition internal combution engine whereby, in a dynamic process, dynamic spark timing retardation values  DELTA  alpha Z1 are stored in an engine speed characteristic curve and added to a predetermined spark timing value  alpha V in order to retard the spark timing. After a waiting time tW, the spark timing is advanced again to the predetermined value  alpha V. The stored dynamic spark retardation values  DELTA  alpha Z1 can be varied in a kind of learning process. If a combustion with pinking occurs during an observation time tB, a dynamic spark retardation value  DELTA  alpha Z1 is increased to a certain retardation correction value or, in the absence of pinking during the observation time, it is reduced to a given advance correction value. The spark timing can thus be adapted rapidly in dynamic processes to achieve optimal operation and a low tendency to pinking.

USE/ADVANTAGE - (I) and (II) can be used for the prepn. of each other. In particular racemic (II) can be converted into racemic (I) which can then be enzymatically sepd. into enantiomer-pure (R)-(II) and (S)-(I). Enantiomer pure (S)-(I) can be used to prepare enantiomer pure (S)-(II) by hydrolysis in the presence of K2CO3. The appropriate enantiomer pure (S)-(II) can then be converted into corresponding enantiomer pure cpds. esp. of formula (III) first either by direct substitution or under the conditions of Mitsinobu inversion to give the corresponding acryl ether, followed by replacement of the halogen by substitution with methylanine, followed by reaction with HCl. R = 2-Me in Tomoxetine, 4-CF3 in Fluoextine or 2-0 Me in Nisoxetine. The 3 cpds. (III) have antidepressive properties. In general, enantiomer pure (I) and (II) are used in the prepn. of pharmaceuticals of formula (IV). (II) are relatively cheap starting materials end conversion into (I) and sepn. into enantiomers is simple and yields are good.

Title: Appts. and process for biological elimination of nitrogen - using microorganisms immobilising on carrier contg. iron turnings
Inventor: KUNZ PETER PROF DR
IPC: C02F1/48
Filed: 1991-09-13
Abstract: In an appts. and process for the biological elimination of N, the micro-organisms capable of oxidn. of NH4/NH3 or nitrite or the redn. of nitrate, are immobilised on a granular carrier contg. Fe turnings, and are added in dependence on the capacity of the appts. at the time, and are removed again. The carrier is pref. sepd. from the slurry/water mixt. magnetically and is led into a washer for removal of unwanted sewage sludge organisms, esp. a washer supplied with a wash fluid contg. special nutrients for reactivation of the nitrificants and other special microorganisms. The carrier with the special mitroorganisms is led into an immobilisation reactor which is fed with inoculant amts. of the water to be treated and also with substances to be broken down. The immobilisation reactor is a cascade, in which each unit can be operated separately. The carrier is scooped out of the water and fed to a dry immobilisation reactor in the form of one or more spray towers. The carrier is conc. in the immobilisation reactor and fed in a controlled way, by a pump or conveyor belt, to the treatment process. The nitrification capacity or other metabolic productivity of the microorganisms is ascertained by continuous determn. of NH4 or other metabolites in the feed and run-off and a determn. of dry matter in the appts., and if capacity drops, carrier with nitrificants or other microorganisms is led into the bio-reactor until the requirement for active microorganisms has been covered. USE/ADVANTAGE - The process is more stable, and the microorganisms are recycled. The carrier is a source of carbonate, which buffers the medium. Used for treatment of drinking water, when denitrification with special microorganisms is needed, or for off-site treatment of waste water with mixed cultures.

Title: Controlling engagement direction within exchange conductor bundle - using traffic direction memory for conductor engagement facility in each engagement direction
Inventor: SCHNABEL HARALD DIPL ING
IPC: H04M7/10
Filed: 1991-10-18
Abstract: The method involves blocking each operational connecting line, with two-directional characteristics, of an exchange in one direction.

A traffic meter (VEME) for each direction determines the value (VWA) of the actual traffic. Each value per engagement direction is compared with an actual line number (LZ) depending on the permitted traffic value (VMZ). The line numbers of engagement directions are automatically changed, when an actual traffic value is higher than the allocated one. USE/ADVANTAGE - For communication exchange control. Automatic adaptation to traffic conditions.

Title: Coating process for membrane surfaces - comprises hydrophobising the membrane carrier to prevent deep penetration of the coating
IPC: B01D71/02
Filed: 1992-01-04
Abstract: By hydrophobising a membrane carrier, a coating is prevented from being too thick and penetrating too deeply into it. Hydrophobising is ceased when the membrane layer is dried. The hydrophobising medium located in the membrane carrier is withdrawn by means of soln. or thermic expulsion and drawn on to the carrier with the aid of a gas mass flow through the membrane layer. The gas current is then further drawn through the carrier, thus further picking up the released hydrophobing medium. The organic skin formation on the membrane carrier has a thickness between 10 and 0.1 microns. USE/ADVANTAGE - To hydrophobise a membrane carrier using synthetic and natural waxes, fats, lard, and plant and animal fats.
