a network of personal computers for the control of an industrial dosing system

the article describes a system installed by ratti spa for the control of dyeing in several factories constituting one of the world's most important makers of high-fashion printed silks, and using daily 1800 batches of dye to produce annually about 5 million metres of fabric in thousands of designs. its objective is to rationalise the reco..

critical slowing down in lipid bilayer membrane studied by a differential ultrasonic resonator

a differential ultrasonic resonator was developed for the measurements of ultrasonic velocity as well as absorption in dilute aqueous suspensions of biological materials. the accuracy of the resonator was improved by analyzing the resonance peak shape with the aid of a microcomputer: the accuracy of 1*10/sup -5/ for velocity and 5*10/sup ..

Neural networks in colorimetry (German)

Measurement and mathematical systems used up to now to evaluate colour have weak points which can be avoided by using neural networks in colorimetry. This paper shows that neural net works based on colorimetric data obtained by reflection measurements of the dyed material can be used as a reliable prediction on visual assessment and light..

Kinetics of the pact process

Kinetics of textile dye removal from a dyeing wastewater was researched. Treatment was carried out in an activated sludge lab plant with powdered activated carbon (PACT). A kinetic model that involved dye adsorption on biomass and carbon and dye degradation by microorganisms was developed. The deduced mechanism of dye removal from the mat..

Effluent treatment of pulp and paper, and textile industries using immobilised horseradish peroxidase

Horseradish peroxidase immobilisation on several supports and its utilisation for decontamination of effluent from paper and textile industries was evaluated. Among the supports, Amberlite IRA-400 ion exchange resin showed the best results for enzyme immobilisation, efficiency of colour removal and degradation of phenolic species from kra..

Decision criteria in stenter buying

Stenter technology is international, but at a very high level, particularly in the case of German suppliers. The state of know-how in fabric and energy transport is mature, and is illustrated in this article. Under these circumstances, one may wonder whether further real drying technology innovations will appear in the foreseeable future.

Automatic dispensing stations

The criteria to be fulfilled for a successful automatic dye dispensing station are briefly outlined software which provides complete cost information, storeroom monitoring and dye recycling. A table is presented with the specifications of the current models from the following manufactures: Kuster Prozestechnik, Thies, Then Naschinen-und A..

Waste water treatment - evaporation under vacuum (Italian) (Trattamento di acque reflue - evaporazione sottovuoto)

Waste water treatment using equipment produced by the Italian firm Led Italia is described. The company designs and produces vacuum evaporators with heat pumps for the treatment of industrial waste water. The polluted water is subjected to a process of separation which produces a distillate and a concentrate. The distillate is purified an..

Biological purification plant for dyeing and printing waste (Italian) (Impianto di depurazione biologica per refluidi tintoria e stamperia)

A biological purification plant produced by the Italian firm Cleaning Srl is presented. Industrial waste is first filtered, then homogenized to produce a constant flow into the treatment area. Next the waste water is pumped to the neutralization pool wher

Reduction of waste water pollution by measures in the sizing plant and during desizing (German)

Waste water from fabric finishing plants contains a considerable amount of size - a substance which has to be applied to the warp yarn so that it can be woven. After weaving the size is washed out of the woven fabric and genrally ends up in the waste water where it is responsible for 40-60％ of the chemical oxygen supply in the water. The..
