Dispersion modeling of particulate matter from ground-level area sources

The new National Ambient Air Quality Standards (NAAQS) for particulate matter less than 2.5 μm in diameter (PM₂. ) and ozone will increase the number of nonattainment areas in the United States. Since a facility is responsible for all PM emissions originating from that property, an increased emphasis will be placed on the regulation of f..

Dispersion modeling of particulate from point and multiple point sources

The Industrial Source Complex (ISC) model is currently the most popular air pollutant dispersion model approved for use by the United States Environmental Protection Agency (EPA) for modeling the dispersion of particulate matter. Agricultural sources of particulate pollutant are among the sources affected by the use of this model. The aut..

Monitoring system for yarn spinning plants

Trutzschler of Germany and Barco, Belgium, have agreed to jointly develop a monitoring system for yarn spinning plants. The Kit system is designed to collect production and quality data for the connection of cards and draw frames. Under the agreement, the German firm will concentrate on teh machine's sensor technology and its network inte..

Rotary spinning ring structure

A rotary spinning ring structure for use on a spinning frame or the like comprises, as principal components, a stationary tube fixedly supported on a ring rail, a slide ring, a rotating tube assembly supported for rotation by the slide ring on the stationary tube, and a balancing mechanism incorporated into the rotating tube assembly. The..

Drafting apparatus and method for producing yarns

A drafting and spinning apparatus is disclosed that produces highly uniform yarns with improved mechanical properties. The apparatus comprises a plurality of pairs of drafting rolls for drawing a sliver formed of one or more types of staple fibers, each fiber type having a predetermined effective fiber length. The plurality of pairs of dr..

A new system for measurement of the properties of intermediate cotton spinning products

A real time, automatic system for measurement of the linear density, parallelization (fiber arrangement rate), moisture content, and composition of the cotton yarn and its blends with other fibers was developed to provide continuous control of these parameters during the spinning process. Devices that are currently available, can measure ..

Improving cotton spinning quality using fuzzy sets

This paper aims at describing the work conducted at Textile Engineering Department, University of Minho (Portugal) in the field of the applications of neural and fuzzy systems on Cotton Spinning. Those days, the field has gained a more solid background by linking to the traditional systems sciences. A textile engineer, who is faced with t..

Intelligent design of cotton mixtures

Problems that are difficult to model in other mathematical ways, because of their complexity, have sometimes show difficulties when the results are compared to those obtained from neural networks. Examining the history of using knowledge based engineering systems and other artificial intelligence related methods, a special conclusion can ..

Automated spinning apparatus and process

A process for conditioning textile fibers comprising the steps of : providing a structure having first, second and third levels ; providing on the second and third levels sliver cans having coiled sliver therein ; providing on said first level ringless spinning apparatuses ; feeding said sliver from said second and third levels ; conditio..
