Filed: 1987-04-25
Abstract: The production of a spun-bonded web from synthetic endless filament in a spun-bonded web apparatus having a spinneret system, a cooling shaft, a drafting gap, a diffuser shaft, a web-depositing conveyor and a device for supplying process air and for sucking off waste air through the web-depositing conveyor. The cooling shaft has shaft walls provided with air-outlet orifices. Process air required for cooling can be introduced through these into the cooling shaft. The air stream is sucked off at least partially through the spun-bonded web forming from deposited loops of endless filament and through the web-depositing conveyor. The depositing length of the loops of endless filament is measured in the finished spun-bonded web over the width of the spun-bonded web. The measured value is compared with a predetermined desired value. In the event of a deviation of the measured value from the desired value, the angle of incidence of pivoting wings arranged in the diffuser shaft and pivotable about a horizontal axis is varied, specifically, in the case of a positive deviation of the measured value from the desired value (depositing length higher than the desired value), the angle of incidence is reduced. <IMAGE>

Title: Method and apparatus for disposing of paint, which cannot be unstuck or are difficult to unstick, from wet-painting installations and paint-spray booths and other industrial sludges from effluent treatment plants or other purification plants
Inventor: PAUSCH GERHARD
IPC: B05B15/12
Filed: 1988-01-15
Abstract: The invention effects recycling of paint sludge from 1-component paints which has not been unstuck with adsorbents or coagulants. The solvent-containing paint sludge adhering to the board fabric belt runs over a flat table surface and the adhering paint is scraped off from the broad fabric belt by means of a doctor blade and, via a kneader, the paint passes into a collection vessel. It can be reprocessed there. The broad fabric belt returns via a reversing roller into a solvent container and is there washed by brushes and the paint residues are removed. The belt is then rolled up again and can be reused at any time. This process effects a recovery of high-value paint completely without cost.

Patent DE-3810720-A1 (DE)
Inventor: SCHULZE-RETTMER RAINER DR
IPC: C02F1/52
Filed: 1988-03-30
Abstract: Process for the purification of waste water (effluent) with a high content of ammonium ions and containing phosphate ions by precipitation of magnesium ammonium phosphate. In a standardisation stage, the ammonium ion content of the waste water is determined and, depending on the magnitude of the ammonium ion content of the waste water, phosphate ions are added if necessary. A slurry of magnesium oxide and/or magnesium ions in excess is added in a mixing stage and the pH is adjusted to the alkaline region. Between the standardisation stage and the mixing stage a pre-treatment of the standardised water is carried out for a residence time of 5 to 30 minutes, during which the ph is adjusted to the acid region. Subsequently, in the mixing stage, the pH is slowly raised to an almost neutral level until an initial turbidity develops. Magnesium ammonium phosphate precipitates out when the pH is increased further. Discharge water materially free from ammonium ions is drawn off.
Patent DE-3811765-A1 (DE)
Title: Alkali mixed-light lamps
Inventor: SCHULZ PAUL PROF DR
IPC: H01J61/22
Filed: 1988-04-08
Abstract: High-pressure discharge lamps having alkali-resistant transparent or translucent discharge vessels are described, whose radiation in the visible spectral range is generated on the one hand by means of the partly reabsorbed yellow resonance lines of sodium as well as from higher excited lines of this metal and, on the other hand, are delivered by higher excited lines of cesium and rubidium as well as from some molecular bands. The resonance radiation from rubidium and cesium lying in the infrared region is suppressed by means of the inherent absorption of these lines at very high pressures. In comparison with sodium, the vapour pressures of rubidium and cesium are essentially higher at the same temperature. At a temperature of 1000 K their pressures are already about 1 bar and increase rapidly with increasing temperature. By means of appropriate dimensioning of the discharge vessels and their loading, temperatures in the coldest places of the discharge vessels of 1200 K and more are aimed at. Since at the highest temperatures the sodium vapour pressures become so high that the yield is substantially reduced by reabsorption of the sodium resonance line, the sodium vapour pressure is limited to 100 mbar to at most 400 mbar in this case by means of appropriate dosing. A radiation of white colour with a high light yield is generated.
