Patent DE-4013278-A1 (DE)
Inventor: EWE ULRICH REINHARD DIPL ING
IPC: B60T13/66
Filed: 1990-04-26
Abstract: An electronic brake control simulates by electronic means various real marches of the pneumatic pressures in a braking system, in particular the pressure in the main air pipe of the train, the pressure in the R-containers of the individual wagons and the pressure in the individual brake cylinders. When the brakes are released, values are determined from these model values and the actually backfed air volume during brake release. The pilot control pressure for a relay valve can be increased by these values in order to release the brakes more rapidly. The train model determines by an adaptive learning method at the end of a brake releasing process values for the volume of the main air pipe and the R-containers of the train, so that the train model adapts itself to the actually existing train.

Abstract: Prodn. of 1,2-dichloroethane (I) comprises oxychlorination of ethylene, HCl and oxygen at 200-250 deg C and 2-6 bar in the presence of a supported CuCl2 catalyst, in a fluidised bed (fluidised with cycle gas). The reaction gases are cooled in 3 condensn. stages, condensed (I) and water are removed, and unreacted ethylene, CO, CO2 and other gases are mainly returned to the cycle. To avoid any danger of explosion, (a) ethylene and HCl are first added (in any sequence or together) to the oxygen-free cycle gas, than an amt. of oxygen is added which is just sufficient for oxidn. of HCl and the inevitable prod. of small amts. of CO and CO2 from ethylene and the non-explosive mixt. obtd. is passed to the reaction zone, (b) the process is operated with an oxygen-free, non-flammable cycle gas contg. mainly ethylene, CO and not above 0.1 vol% oxygen (i.e. outside the explosive range), and (c) 1.6-1.9 pts. vol. oxygen-free cycle gas is used as diluent for each 1 pt. vol. starting materials (ethylene + HCl + oxygen). USE/ADVANTAGE - The risk of explosion in the prodn. of (I) is reduced and simplified instrumentation is used. The yield of (I) is also increased to about 98% w.r.t. ethylene.

The drives for the drums (1, 2, 3) rotate each drum faster than its preceding drum. The washing drum (1) and the spray drum (2) are next to each other in the housing (5), and the drying drum (3) is below the spray drum (2). A collecting vessel (8) is below the spray drum (2), connected to the catch basin (39) below the drum (2) by a return flow channel (40). An oil extractor, working with the supply vessel (7), gives clean washing medium for recirculation. A conveyor belt (14), as a magnetic belt (14), carries the workpieces between the outlet side of the washing drum (1) and the inlet side of the spray drum (2). ADVANTAGE - The washing machine can be located at the position where the workpieces are machined, so that they can be cleaned rapidly without affecting the environment.
