摘要:
The invention relates to a process for the adaptive correction of the shifting quality of an automatic transmission which is coupled to an engine and in which correcting elements acting on the pressure or oil throughput bring friction elements into engagement in the form of clutches or brake bands to carry out shifting processes, the line pressure impinged on by the correcting elements being registered by means of an electronic device and corrected as a function of various operating parameters. In this case for each specific gear change besides the resultant translation ratio (R) as a function of the time from the initiation of the shifting process until its completion, also the first derivative (dR/dt) is formed and in the electronic device (1) values of the translation ratio (R) are assigned to the corresponding values of the first derivative (dR/dt) in the form of a characteristic line, said measured characteristic line being compared with reference characteristic lines present in the device (1) including a tolerance range and that in the case of inequality a correction factor (KF) is determined which upon the next identical gear change leads to an incremental increase or a decremental decrease in a correction value (K.sub.x) by the correction factor (KF) and thus causes a correction of the line pressure or the oil flow by means of the pressure or oil flow-impacting correcting elements (8, 9) modulated by the electronic device (1) corresponding to the correction value (K.sub.x).

Method for operating a charging station for electric vehicles in which a charging power is negotiated between a charge control device of the electric vehicle and the charging station, the charge control device controls a charging current which is transmitted from the charging station to the electric vehicle in accordance with the charging power negotiated, wherein a continuous power rating and a maximum power of the charging station which is greater than the continuous power rating are determined. In order to optimize the charging power and to accelerate a charging operation, it is proposed that a charging power which is above the continuous power rating and which at most corresponds to the maximum power is first negotiated, that the temperature in the charging station be monitored, and that, when a limit temperature is exceeded, a new charging power which at most corresponds to the continuous power be negotiated.

A method is provided for dynamically providing up-to-date information about charging stations for electric vehicles. Charging station information including at least one charging station identification assigned to a respective charging station and location information assigned to the respective charging station is stored for multiple charging stations. A charge request containing identification of the mobile station and geographical information for the mobile station is received from a mobile station. A tuple of charging station information from the plurality of items of stored charging station information dependent on at least the received charge request is selected such that the received geographical information is compared with the respective location information of the charging stations and when the result of a comparison is positive the corresponding charging station information is added to the tuple and the tuple is sent to the mobile station using the identification of the mobile station.
摘要:
A process for rapidly mixing phosgene and an amine in the gas phase to produce the corresponding isocyanate. Micro-structure mixers are used for the rapid mixing. The educts emerge from the micro-structure mixer in the form of thin free jets which mix very rapidly by diffusion and/or turbulence. As a result, the mixing operation is accelerated substantially as compared with conventional reactors. The isocyanate yield is also increased.

Polyether polyols are made by alkoxylating a mixture which is from 20-80 weight % sucrose and 80-20 weight % formitol. The product polyether polyols have an average hydroxyl functionality of at least 3 and a hydroxyl number of from 28 to 1000. These polyether polyols are particularly useful for the production of rigid polyurethane foams.
