Abstract: A converter has an invertor arrangement which is furnished with power semiconductor components. In the event of high voltages in the DC intermediate circuit, the rated voltage and the rated insulation voltage of the power semiconductor components in the invertor arrangement must be taken into account. Conventionally, the invertor arrangement was furnished with power semiconductor components whose rated voltage and rated insulation voltage exceeded the voltage in the DC intermediate circuit. In order to be able to use semiconductor components with lower rated voltages and rated insulation voltages, that is to say, in particular, cheaper components, the invention proposes connecting a plurality of invertors in series, that is to say in cascade, so that only a proportion of the overall DC voltage is applied to each partial intermediate circuit produced in this way, so that the power semiconductor components in each invertor can be components with a low rated voltage and rated insulation voltage. The invertors are regulated by a regulator device such that the voltage breakdown is equal within the invertor cascade. Controlled resistor arrangements are provided on the individual invertors or the invertors which are connected in groups, to protect against the voltage surges which occur briefly in the event of disturbances in the system. <IMAGE>

Abstract: With a brake valve, the pressure in a brake line is to be controllable in a linear and continuous manner in as large a range as possible, from for example 0 - 5 bar, by swivelling a lever. The use of the previously customary screw to change the spring pretensioning is only possible for small pressure ranges. With the aid of a lever (20), the ratio between the force (A) of the spring (16) and the force (B) brought about by the brake line pressure is controlled, the effective lever arm lengths (I1, I2) being adjustable by means of a brake lever (10, 46). The spring (16) rests on a circular segment- shaped support face (22) by means of a roller (18) in such a way that the spring force remains constant during the swivelling of the brake lever (10, 46). <IMAGE>

Abstract: There are time-division multiplex communication systems in which digital signals which are asynchronous with the pulse frame and consist of successive blocks whose beginnings are marked with sync words are inserted into the pulse frame. The resulting jitter of the sync words ("waiting-time jitter") is reduced by a circuit which derives from the clock of the received sync words a sync signal (SY) that exhibits less jitter than the clock of the received sync words. According to the invention, the circuit contains a measuring device which measures the time intervals (N) between the sync words, a filter (F) which takes the average (N') of the time intervals (N), and a signal generator (S) which forms the sync signal (SY) from said average (N') in such a manner that the pulse period of the sync signal (SY) is equal to said average (N').

Abstract: The device for calculating the tariff, preferably intended for an electricity meter, exhibits a microprocessor (1), a data memory (6) and a bidirectional interface (8) for data transmission with a reader. A timing section (9) is activated for the duration of a data transmission and, via a logic circuit (10) blocks a predetermined storage area (6a) against being loaded with data. The data stored in the storage area (6a) and used for accounting purposes are thus protected against unintentional changes during the data transmission even if the software has corresponding errors. The function of the timing section (9) and of the circuit (10) can be checked in a simple manner. Objections with respect to the data security during a bidirectional data transmission are thus without substance. The device for calculating the tariff is therefore suitable for calibration.

Abstract: The invention relates to a microfiltration process, in particular for separating beer from a materials flow which is purged during the fermentation process and which takes along the excess yeast produced during the fermentation, wherein the materials flow containing haze substances to be filtered is passed under pressure through at least one microfiltration module with porous membranes carrying a tangential flow and a filtrate is taken off. According to the invention, the materials flow to be filtered is continuously fed to a circulated retentate flow, and a concentrate flow having a substantially constant concentration of haze substances is taken off from the retentate flow. The flow velocity and the flow pressure drop of the retentate flow are measured and the concentration of haze substances in the retentate flow is determined from the measured data according to a function F (v,  DELTA p) which is characteristic of the apparatus and which contains the flow velocity (v) and the flow pressure drop ( DELTA p) as variables. The concentrate flow rate is controlled in accordance with the difference in the concentration of haze substances, resulting from a comparison of actual and set values.
