Title: Device for plasma processing of textile materials
Inventor: ZELDIN YULIJ R
IPC: D06M10/00
Filed: 1990-01-29
Granted: 1995-01-20
Abstract: FIELD: textile industry. SUBSTANCE: device has chamber connected with evacuation system and provided with contrivance for plasma processing. To process material with low density, for example, gauze, guiding rollers are mounted according to "loop-in-loop" order. Electrodes of plasma processing system are disposed in internal spaces of any double loop. In this case active particles of plasma pass through material under processing due to openings available in the material. In order to process material with higher density when active particles of plasma can not pass through material as they are caught by surface layer of the material, it is desired that material under processing would be turned to electrodes with its face side every time. As a result, only face side of the material is processed. EFFECT: reduced power consumption; improved efficiency. 1 dwg

Analyzer is learned before measuring stage and learning stage has given duration and much smaller than measuring one. During learning stage analyzer is acquires information about amplitude as well as frequency characteristics of random process. This results in possibility to select step of time for process sampling as well as corresponding step of sampling level and duration of learning and measuring stages when characteristics of random process are absolutely unknown a priori while hardware and statistic errors are in given permissible limits. Average interval between adjacent extremum values of process is used as step of time for sampling. Step of sampling by level is proportional to average half-range of measured process. Duration of learning and measuring stages are determined by accumulation of given number of extremum values of process and is in inverse proportion to range of its power spectrum.
