Filed: 1982-07-16
Abstract: The invention relates to a method and a corresponding technical equipment/device which is intended, particularly in telephone operation, to allow the telephone set used as the calling unit (information source) to notify its own telephone number automatically to the called telephone set. This method can also be used for alarm signalling. In technical terms, the equipment/device comprises a read-only memory (ROM), a modulation and demodulation unit (modem) and a digital display with/without a printer. The allocated telephone number of a respective telephone set is held in binary coded form in the read-only memory. The task of the modulation and demodulation unit is to convert the DC signals of the respective read-only memory into AC signals on the calling unit side. On the called unit side, DC signals are reproduced from the AC signals and fed to the digital display with/without a printer. It is of crucial importance here that the equipment and/or signalling features of the different functional units of the PTT match those of this invention, particularly in terms of matching connections.

Inventor: GATTYS FRANZ JOSEF
IPC: C01F5/30
Filed: 1982-07-20
Abstract: Chlorinated salts are recovered as recycling material from waste solutions, for example magnesium chloride from waste waters of the potassic fertilizer industry by thermal concentration of the solution in direct contact with flue gas. In the flue gas, the ratio in molecular amounts between nitrogen monoxide and nitrogen dioxide is adjusted by addition of the missing oxide from external sources and 1.5 to 2 moles of magnesium oxyde per mole of sulfure dioxide and nitrogen dioxide contained in the flue gas are added to the solution. Thereafter, the saturated solution is concentrated and subjected to a fractionated crystallization so as to recover on one hand the sulphurous compounds and on the other hand the nitrites and nitrates. Then, the fractions are subjected to a treatment by pyrolysis.

Title: Method and device for restacking flat textile structures
Inventor: KUSS PETER DIPL ING
IPC: B65H83/00
Filed: 1982-10-04
Abstract: The solution according to the invention serves for the restacking of flat textile structures, in particular of cut pattern parts for items of clothing, in a manner appropriate for processing, which flat textile structures cannot be further processed in the stacking form predetermined by the pattern cutting technology. According to the invention, by means of a displaceable separating device having two separately vertically movable receivers, in each case one part is removed from the stack of cut pattern parts and restacked alternately to the right or the left. In this case, the receivers operate in an opposite manner, i.e. while the one receiver picks up a cut pattern part from the original stack of cut pattern parts, the other receiver places a cut pattern part on the right or left stack. The horizontal movement of the overall separating device and the vertical movement of the receivers can be implemented by means of pneumatic operating cylinders. <IMAGE>

Patent DE-3342051-A1 (DE)
Title: Process and apparatus for sludge thickening
Inventor: OERTLE JAKOB
IPC: C02F11/127
Filed: 1983-11-22
Abstract: To thicken thin sludge to a desired concentration, a part (2) of the thin sludge is fed to a centrifugation device and is thickened there to a concentration above the desired concentration. The thickened sludge is mixed with the remaining part of the thin sludge in a mixing vessel (8) so that the desired concentration is established. The thick sludge is fed into the mixing vessel (8) at the top of the vessel and the thin sludge is fed in the horizontal direction at the bottom of the mixing vessel (8). The mixed sludge is withdrawn at the bottom via a circulation device (10, 11, 12) and returned at the top of the mixing vessel. The homogeneously mixed sludge, after repeated circulation, leaves the mixing vessel via an overflow (13). Homogeneous mixing is achieved during this with small dimensions of the mixing vessel (8) which are in the same order of magnitude as those of the centrifugation device (4). This can thus be arranged directly above the mixing vessel (8) in such a manner that its outlet (9) lies above the thick sludge intake (19) of the mixing vessel and the thick sludge passes under its own weight into the mixing vessel. Such an apparatus is particularly suitable for thickening sewage sludge in waste water treatment plants. <IMAGE>
