摘要:
An arrangement for fastening a housing (3) is proposed for receiving for instance a force converting transmitter or pickup in an opening of a wall (1) transmitting the force to be measured, to assign a radially expandable clamping or tightening sleeve 5 to the housing (3) and to provide a wedging connection (8, 9) between the housing (3) and the clamping sleeve (5), whose external diameter corresponds to the diameter of a cylindrical bore (2) configured in the wall, which wedging connection can be brought into operational effect by means of a clamping or tightening element (6) connectible with the housing (3).
摘要:
A data-transmission device has a pulse generator (1) and a monitoring unit (20) for use in a vehicle. A signal generated by the sensor (2) is transmitted from the pulse generator (1) to the monitoring unit (20) by a signal line (9) and also, when requested by the monitoring unit, is transmitted in encrypted form along a data line (19). The signal generated by the pulse generator (1) is first stored in an intermediate store. Before transmission, the contents of this store are encrypted. On arrival in the monitoring unit, the encrypted signal is compared with the signal previously transmitted in the usual way and recorded there. This is a security check which reveals any manipulations which have been made during transmission.

An apparatus for recording driving data which comprises a data gathering device, which further comprises a sensory measuring device, a control unit, an A/D converter, a plurality of parallel ring storage devices and a semiconductor storage device. Analog measurement signals, which are continuously detected by the sensory measuring device, for recording a vehicle movement, are continuously sensed by the control unit with two different frequencies after being digitized into digital measurement signals in the A/D converter. The digital signals are stored in the plurality of parallel ring storage devices with clock frequencies. Upon a detection of an accident, a trigger signal causes the control unit to stop storing the digital measurement signals in a first of the plurality of parallel ring storage devices with a lower clock frequency after a delay so that a storing of measurement data in the first of the plurality of parallel ring storage devices terminates one of after an after-running period and as a result of a stopping of the vehicle. The control unit interrupts a further storage of the digital measurement signals in a second of the plurality of parallel ring storage devices with a higher clock frequency at the occurrence of the trigger signal and causes the digital measurement signals to be stored in the semiconductor storage device. The semiconductor storage device is arranged in parallel with the second of the plurality of ring storage devices and has the higher clock frequency for the duration of the trigger signal.
摘要:
A method for positioning a switch in a speed limiting device, wherein, for a limit switch, which interrupts the controlling process of the speed limiting device consisting of an electronic control unit, an electromechanical servo unit and a mechanical clutch arrangement, a positioning method is utilized and in order to carry out this method, an arrangement is provided in which the limit switch is fastened on a slide which is displaceably supported with the servo component of the speed limiting device. Arranged in the slide, which, in addition, carries a switchover contact bank serving to actuate the switch, there are provided locking bars with which, together with catch paths constructed at a housing of the servo unit, an exact fixing of the slide can be achieved at the end of the positioning process by means of reversing the rotational direction of the servo motor.

A device for recording time markings on a speed graph in a tachograph includes a support mounting a pair of rods on which a slide is movably displaceable. The slide supports a recording member or stylus for marking the graph. An electromagnet is arranged to tilt the slide and laterally displace the stylus for a brief period of time in the direction of the time coordinate of the tachograph for effecting a marking on the speed graph.
摘要:
A housing of the apparatus has two sections which are relatively pivotable between an open and a closed position. A drive is provided in one of these sections for rotating the record carrier and includes a rotary support for the record carrier and a spindle which extends through a center opening of the record carrier. A self-centering element is provided in the other housing section, being mounted therein with freedom of play so that it can center itself relative to the spindle in response to movement of the housing sections towards their closed position, the element being adapted to snap in its centered position against a record carrier on the support when the housing sections move to their closed position, so that the element rotates with the support and record carrier.
