Patent DE-3812013-A1 (DE)
Title: Electronic measuring device
Inventor: LENKEIT JUERGEN
IPC: B65H59/40
Filed: 1988-04-11
Abstract: An electronic measuring device - a tractive-force measuring device in accordance with the illustrative embodiment - with a measured-value pick-up and an indicating instrument connected thereto via a cable enables the effective value of the measured quantity - the tractive force in this case - to be read off on a digital display by means of a voltage divider formed from two resistors, the first resistor of which is located within the indicating instrument whilst the second resistor, which is tuned to the rated load of the test probe, is arranged in the measurement-value pick-up, the resistor being designed in such a manner that the RMS value of the tractive force is indicated on the digital display. The resistor arranged in the measurement-value pick-up is specific for this pick-up so that a universal combination of measured-value pick-ups and indicating instruments is possible by a mere plug-in connection.
Patent DE-3813985-A1 (DE)
Title: Attachment device for rain-inlet shafts or similar structural parts
IPC: E03F5/02
Filed: 1988-04-26
Abstract: Rain-inlet shafts are used in road construction and are installed manually by construction workers. Up until now, there has been no attachment device for rain-inlet shafts in order to fit these by means of an excavator or similar building-site vehicle. A simple attachment device makes it possible to instal said shafts mechanically and brings with it the advantages, on the one hand, of saving a considerable amount of time and, on the other hand, of not taking up any additional space around the shaft, this likewise resulting in a saving in costs.

Patent DE-3829619-A1 (DE)
Inventor: HARTMANN UWE
IPC: H04N5/59
Filed: 1988-09-01
Abstract: In a television tubes with large screen and large angle of sweep, the light density may be greater in the centre than at the edges because the electron beams do not strike the edges at right angles as they do the centre. The arrangement proposed modulates the screen-grid voltage of the television tube so that it is greater at the beginning and end of a line than in the centre of the line.

Patent DE-3835630-A1 (DE)
Title: Method for generating a frequency modulation
Inventor: DIRR JOSEF DIPL ING
IPC: H04J3/16
Filed: 1988-10-19
Abstract: In the previous circuits for generating a frequency modulation, a large number of side oscillations were produced above and below the carrier, the number being dependent on the modulation index. These side oscillations also determine the bandwidths. In the invention, the side oscillations are avoided in that the amplitudes of code pulses or of PAM pulses are converted into pulse duration pulses and after that are shaped into square width pulses, for example by means of an electronic relay. Using a low-pass filter, the square width pulses are then converted into a sinusoidal alternating current. The periods of the pulse duration pulses, of the square width pulses and of the halfwaves or periods of the sinusoidal alternating current are always the same so that the change in the PDM pulses also results in a change in the frequency of the coding AC, this therefore being a frequency modulation.
Patent DE-3836887-A1 (DE)
Title: Closing device as insertion preventer for magnetic-tape cassettes, in particular video-tape cassettes
Inventor: MUELLER HANS-FRIEDRICH DIPL IN
IPC: G11B23/28
Filed: 1988-10-29
Abstract: A closing cylinder is intended to prevent the unauthorised reproduction of a recording on video tape. According to an exemplary embodiment, this is performed by the cylindrical core 1 being inserted into a cavity of the video-tape cassette 4 which is unoccupied and accessible from the outside, namely into the round opening provided for a transmitting diode (d = 12 +/- 0.2 mm), the diode opening 8. When the key is withdrawn, the tumblers 6/7 move into the light window 9 of the video-tape cassette 4. The cylindrical core 1 terminates flush with the main outer side of the video-tape cassette 4 and, together with two projections 2/3, blocks a passage of the control groove 5, crossing the diode opening 8. Normally a feeler in the video recorder mechanically senses the correct position of the video-tape cassette 4. Since, however, the cylindrical core 1 located in the diode opening 8 blocks the passage of the control groove 5, the video-tape cassette 4 is not accepted by the video recorder, thereby preventing the reproduction of a magnetic recording. <IMAGE>

Patent DE-4019927-A1 (DE)
Inventor: KUNKEL HORST
IPC: G01S17/04
Filed: 1990-06-22
Abstract: The circuit arrangement comprises a transmitter (3) and a receiver (4), to which a radiation emitted by the transmitter (3) passes back after reflection on an object (7). In an initialisation process which occurs for the first time after the installation and thereafter at greater regular time intervals, the power of the transmitter (3) is increased until the reflection on a stationarily existing object (7) within the detection range leads to the evaluation circuit (5) following the receiver (4) being triggered. The power of the transmitter (3) is then slightly reduced again; the circuit arrangement returns to normal operation. It now has its optimum sensitivity at which stationarily existing objects (7) no longer cause faulty triggering actions but the greatest possible detection range is given for moving objects to be detected.
