Patent DE-2847486-A1 (DE)
Inventor: EBNETH HAROLD DIPL CHEM DR
IPC: H05K9/00
Filed: 1978-11-02
Abstract: Metallized sheet-form textiles of synthetic polymers or natural fibres to which a metal layer has been applied by wet-chemical currentless deposition are particularly suitable for screening electromagnetic waves in the range from 10 MHz to 1000 GHz. Since the textile properties are substantially unaffected by the metallization, the sheet-form textiles are particularly suitable for use in the medical and communications fields. A multiple-layer construction with insulating intermediate layers and surface linings may be useful, for example in the screening of relatively low frequencies.

Title: Reader for transported containers - uses light reflecting dash code for decimal symbols and four-lens reading head for each decimal position
Inventor: SEITZ PETER
IPC: G06K7/10
Filed: 1979-04-02
Abstract: The reader is used for moved transport containers, simultaneously converting the read decimal values in parallel decimal signals. For all decimal figures a dash coding is used. Each decimal symbol is represented by a four-member group for alternately light reflecting coding dashes with individual values of 1, 2, 4 and 8. A four-lens reading head is allocated to each decimal position, e.g. unity, ten, hundred etc. All reading heads are arranged in a line, one behind the other, in the transport direction of the containers. The heads for the decimal positions are supplemented by tripping heads, switching in the line of heads on simultaneously illumination. The parallel recieved binary signals from the reader head line are converted in a decoder into parallel transmitted decimal signals. Each four-lens head has pref. four lens pairs across the container transport direction for transmission of a light signal and for reception of a reflected one.
Patent DE-2915359-A1 (DE)
Inventor: GASSMANN GERHARD G
IPC: H04N5/44
Filed: 1979-04-14
Abstract: Standard television signals, with an image constituted by two interlaced partial images are stored in a buffer memory (13, 14, 15) and the partial images are treated therein in order to obtain entire images without insertions and with an image frequency higher than that of the standard image signals. These images are extracted from the memory and reproduced on the screen, in order to simplify the circuits, it is necessary that the number of entire images reproduced in a time interval should be equal or greater than the number of partial images received during the same interval and that at the same time the relation between these two numbers should be an entire fraction, that is to say that the numerator and the denominator should be entire numbers and that the value of the fraction lies between 1 and 2. It is also necessary that the sequences of the partial images and the entire images should be timewise arranged in such a way that at least certain of the transition of the entire images overlap repeatedly with the transitions of the partial images.

Title: Structured fabric patterning - uses transfer paper with pleated fabric which is then smoothed and fixed
Inventor: KLEBER KURT
IPC: D06C23/04
Filed: 1979-07-16
Abstract: To achieve a structured patterning on smooth materials, the fabric is mechanically pleated, and then progressively warmed continuously. The pleated folds are undone, and fixed by cooling. Also claimed is a process in which, before the application of heat, a web of thermal printing paper is fed to the pleated fabric, and the web and fabric are pressed together in alternating layers of fabric and paper. They are then heated to effect the transfer of dye and/or pattern from the paper to the material. The paper carrier is then removed from the fabric. The fabric, while still warm, is stretched to smooth out the pleats, and then wound into a roll for cooling. The fixed fabric structure allows colour to be applied so that the general effect is a partial and structured patterning.

Title: Conference facility for delta modulation telephone exchange - combines all speech signals and suppresses noise in pauses, and reconverts processed signal
Inventor: SCHADE GERD ING GRAD
IPC: H04M3/56
Filed: 1979-08-31
Abstract: The telephone exchange uses delta modulation of speech signals and has a conference facility which combines the signals from all participating subscribers and sends the combined signal to all of them. After conversion to delta modulation, each input signal is processed in a series of shift registers which form the first and second derivatives, using the second to control formation of the first. All the first derivative signals are then added. The summation signal is further processed by shift registers and logic gates. In particular, when the demodulated signal would be below a threshold, it is replaced by alternate 1s and 0s, with the object of suppressing noise. The processed summation signal is then converted back to delta modulation, demodulated and sent to all subscribers via a low pass filter.
