Title: Noise suppression circuit for communications channels - cancels independent noise components by adding signals together
Inventor: TURBAN KARL-ALBERT DR ING
IPC: H04B15/00
Filed: 1979-01-20
Abstract: The noise suppression circuit has its input signal divided and passed along two paths each exhibiting noise independent of the other. An output signal is constructed from the signals from these two paths such that the output signal is proportional to the sum of the outputs. The two paths have approx. identical transmission and noise properties. If the signals are recorded then at least two recordings are made of independent noise. A resultant signal is derived from the replay signal such that the resultant is proportional to the sum of the replay signals. The independent noise components in the two signals largely cancel one another when the signals are added.

Title: Acoustic signalling circuit for cooker - has switch applying mains volts to NTC resistor in series with buzzer so sound increases gradually
Inventor: MAGG JOHANN ING GRAD
IPC: A47J27/212
Filed: 1979-02-06
Abstract: The circuit consists of an NTC resistor (8) in series with a signalling device (6). The resulting series combination can be connected to the main supply via a change-over switch (4). The latter connects either this series combination or the heating element (2) to the supply. The change-over switch is operated when a given temp. is reached, e.g. when water has boiled. The current through the signalling device, e.g. a buzzer, gradually increases so that the sound liewise gradually increases. Alternatively, a PTC resistor may be connected in parallel with the buzzer and the parallel combination connected via a ballast resistor and the change-over switch to the mains. The effect on the buzzer's sound is the same as before.

Title: Dimensional measurement of rolled goods - using diode row scanning back of goods illuminated with sodium lamp
Inventor: RIECH VOLKER DR ING
IPC: G01B11/04
Filed: 1979-05-21
Abstract: A device measuring dimensions of luminous rolled goods contains a camera with a self-scanning diode line. It achieves effective suppression of stray light and saturated illumination of the diode row. This enables a higher measurement accuracy to be achieved. A monochromatic light source is placed on the opposite side of the goods from the camera. An optical and pass fitter is placed between the article and the camera. The light source is a low pressure sodium vapour lamp connected to the 50Hz power supply. The diode row scan time is thus fixed at 10 milliseconds. The high beam intensity of the sodium lamp enables the use of smaller diodes than with conventional arrangements. This achieves the increase in accuracy.
Patent DE-2921243-A1 (DE)
Inventor: CENKER RONALD P
IPC: G11C29/00
Filed: 1979-05-25
Abstract: The storage space of the instant system is considered, for refresh purposes, to contain 512 groups of 26 bit digital words with each group containing 128 such words. Memory refresh is implemented by sequentially refreshing the groups of digital words at the rate of one group every 2.8 microseconds, giving an expected total memory refresh time of approximately 1.43 milliseconds. A particular digital word from each group of digital words refreshed is read from the memory and transmitted to a parity check circuit which generates fault signals for any digital word having faulty parity. At the end of each of the approximately 1.43 millisecond refresh cycles, the particular word read from each group refreshed is changed so that at the end of 128 full refresh cycles (approximately 184 milliseconds), the parity of every digital word in the memory has been checked. Further, circuitry is provided to store the location of the first failing digital word in a trap register in response to an indication of faulty parity.
