Title: Method for automatic two-position control
Inventor: MAGERGUT V Z
IPC: G05B11/54
Filed: 1996-12-30
Granted: 1999-04-27
Abstract: FIELD: automatic control equipment, in particular, for regulation of characteristics in industry and home appliances. SUBSTANCE: method involves setting five levels for signals to be regulated: nominal level, which is equal to given value and serves for switching positions of regulator, two adaptation values, which differ from nominal level by ±δ, and two re-adaptation values, which differ from nominal level by ±Δ;  . When signal of regulated value runs out of adaptation range, method involves alternation of value of signal of position which does not influence object at the moment by step ΔU towards its convergence with signal of actual position. When signals runs out of re-adaptation range, current position is assigned to its extreme value. In addition method involves continuous comparison of signals of positions. EFFECT: improved quality of two position automatic control for objects with alternating load. 2 dwg

Filed: 1997-09-01
Granted: 1999-09-10
Abstract: FIELD: radioactive compounds technology. SUBSTANCE: method can be used in extraction processing of uranium solutions and in selecting extraction systems assuring safe process conditions. Stability of extractant-nitric acid systems is determined from degree of extractant-nitric acid interaction involving fixed-temperature heat treatment of samples with different initial concentrations of nitric acid in aqueous phase and equilibrium concentration of nitric acid in extractant. For each temperature, equilibrium concentrations of nitric acid in aqueous phase corresponding to starting interaction are determined and curve for temperature dependence of these equilibrium concentrations is plotted, this dependence being indicative of stability region. Values of above equilibrium concentrations are found in points obtained by extrapolation to abscissa of linear sections of curves depicting dependence of optical density of solution colored by nitro compound of thermally treated extractant on equilibrium concentration of nitric acid in aqueous phase. Solution for determining optical density is prepared by adding thermally treated extractant aliquot to alcohol solution containing 0/1 M KOH.
