ALGORITHMIC SUPPORT OF THE AUTOMATED INSTALLATION FOR MEASURING THE MATING AND UNMATING FORCE OF ELECTRIC CONNECTOR CONTACTS

Algorithmic support is proposed for an automated installation for measuring the mating and unmating force of the electrical connector contacts, which allows obtaining objective data while testing with the possibility to register the fixed force. The developed system also provides inputting and editing test parameters applying the operator's touch panel using the Human–Machine Interface, local visualization of the measurement process, support for implementing the parameters storage in non-volatile memory with logging the test information. The ability to automatically measure the mating and unmating force of an electrical connector reduces the impact of human error on test results, increasing the accuracy and the process productivity.

AUTOMATED INSTALLATION FOR MILK COOLING USING A NATURAL COOLING AGENT

In the chain from milk production to the sale of dairy products, the process of ensuring the required temperature is the main one. Moreover, to cool the milk, the tempera-ture of the cooling agent should be above milk freezing. Taking into account the fact that the process of cooling and storing milk in a chilled form imposes strict requirements for reliability and quality of management on farms, compressor refrigeration units have been used in recent years despite high energy consumption. Theanalysis of technical solu-tions in this direction by the example of farms of the Altai and Novosibirsk Regions showed that during the greatest boom of the livestock industry, film-tray, spray-cooling tow-er, and pipe and tank installations using natural cooling agents were widely used. Taking into account the climatic features of the area when choosing water cooling units as an intermediate coolant made it possible to significantly reduce energy consumption for milk cooling especially in winter. However, the complexity of controlling the process of preparing the intermediate coolant with unpredictable environmental parameters did not allow for high reliability and quality of manual control. A device for cooling the in-termediate coolant with the main -natural cold in winter with an automatic direct-acting regulator that provides the required operating mode of the cooling unit is proposed. The variants of automatic device operation both when the outdoor air temperature decreases and increases are con-sidered. An automated installation for cooling the interme-diate coolant with natural cold may be recommended both for cattle farms and processing enterprises

INFLUENCE OF THE NANOCLUSTER {MOFE} POLYOXOMETALATE ON OXIDATION OF IODIDE-IONS BY PERSULFATE

Изучены каталитические свойства нанокластерного железомолибденового полиоксометаллата {MoFe} в растворах при реализации окисления персульфатом йодид-ионов. Использована автоматизированная установка на базе спектрофотометрического метода анализа, управляемая компьютером. Сравнение литературных данных и кинетических данных окисления иодида персульфатом показывает, что кеплерат является гетерогенным катализатором. Эти данные позволяют предполагать нерадикальный механизм для разложения персульфата на поверхности молекул кластера на первой стадии реакции окисления иодида калия. Значение эффективной энергии активации процесса указывает на каталитическое воздействие {MoFe} на промежуточной стадии разложения пероксида водорода. Catalytic properties of the nanocluster iron-molybdenum polyoxometalate {MoFe} in solutions during the oxidation of iodide ions by persulfate have been studied. Automated installation based on spectrophotometric method of analysis controlled by computer was used. Comparison of literary data and kinetic datа on the oxidation of iodide with persulfate showed that keplerate {MoFe} is a heterogeneous catalyst. These data allowed to assume a non-radical mechanism for persulfate decomposition on the surface of cluster molecules at the first stage of the potassium iodide oxidation reaction. The value of the effective activation energy of the process indicates the catalytic effect of {MoFe} at the intermediate stage of the decomposition of the hydrogen peroxide.
