Abstract: A method and apparatus for determining wear and tear in machines includes a method that determines a voltage draw and/or a current draw of a first subsystem of the machine during its operation, and wear and tear present in a second machine subsystem is determined based on the draw determined in the first subsystem. In one embodiment, a coal grinding machine includes a drive, a coal grinding mill driven by the drive, a device for determining an electrical draw of a current and/or voltage draw of the drive during operation, and a device for inferring wear and tear present in the coal grinding mill on the basis of voltage and/or current draw determined in the drive. The machine can include a device for inferring the quality or type of material (like coal) being processed in the mill based on the draw determined in the drive.

Abstract: A specific failure occurring during operation of a technical installation is detected by acquiring an acoustic and/or optical signal emitted by a device assigned to at least one component of the technical installation whereby the device is being activated mechanically.

Abstract: The invention relates to a cassette for receiving a stack of sheets, with a pressing element which bears against a first end face of the stack of sheets and is movable in the pressing direction, with a drive motor for displacing the pressing element so that a second end face the stack of sheets facing away from the pressing element can be brought to bear against extracting elements of a sheet extracting device, and with a measuring device for determining the pressing force of the stack of sheets against the extracting elements an output signal of the measuring device serving for controlling the drive motor in order to generate a predetermined pressing force. The stack of sheets and the pressing element are arranged in a slide which is accommodated in the cassette movably in the direction of displacement of the pressing element, the pressing element being displaceable with respect to the slide by the drive motor.

Abstract: A process of scanning and evaluating binary data stored on a magnetic track of a magnetic storage card includes a calibration at the beginning of the scanning operation with certain information stored on the card and a determination of a calibrated time interval. A time curve of the output signal in the calibrated time interval is registered and compared to predefined curve patterns in order to determine deviation of the registered time curve from the curve patterns. A curve pattern showing a least deviation from the registered time curve is identified. The curve pattern may be selected on the basis of information obtained from a previously determined output signal curve. Also, the extreme values are detected to obtain information stored on the card.

Abstract: In a process for evaluating binary data stored on the magnetic track of a magnetic storage card (10) in the form of flux changes in accordance with the two-frequency code, a relative movement (v) is produced between the magnetic storage card (10) and an electromagnetic transformer (30) which emits voltage pulses induced by the changes in magnetic flux. The time intervals between the voltage pulses are evaluated in order to obtain the data. To this end, standardization is carried out with uniform preliminary data at the beginning of a scanning operation. The output signal (U) of the electromagnetic transformer (30) is converted to digital values at predetermined times. The digital values are stored in the sequence in which they are stored and evaluated in order to obtain the data.

Abstract: A character generator which converts character code words into data items, namely column code words (C code), for controlling a dot matrix output unit, is disclosed. The character code word is presented to an address memory circuit which generates a ten-bit-long column address (CAD) that identifies the locations of the column code words within a separate data storage unit. The address memory circuit includes two memory units (PROM 1, PROM 2) which store only the first eight bits of respective column data addresses, while an additional memory unit (PROM 3) stores the remaining two bits of the respective column data addresses. A multiplexer (15) is used to select the correct two bits of each respective column data address from an eight-bit word output by the additional memory unit (PROM 3) at the same time an eight-bit address is being output by one of the first two memory units (PROM 1, PROM 2).
