Production of high-temperature claydite from loams of the Vladimirovskoe Deposit

The possibility of producing high-temperature claydite on the basis of low-grade overburden rocks (loams) of the Vladimirovskoe Deposit is considered. The correcting additives are taken from industrial waste, namely, solar oil and chamotte-kaolin dust from electric filters of rotary kilns.Translated from Ogneupory, No. 4, pp. 26 – 28, April, 1996.     

Analytical solution of a system of nonlinear measuring equations of a 12-pole microwave reflectometer

Analytical solution of a system of nonlinear measuring equations of a 12-pole microwave reflectometer was obtained. Criteria for selecting a true solution in the general case were developed and the analysis was conducted for a number of particular cases that may generate practical interest.     

Digital forecasting control with the use of neural predictors

The use of prognostic control methods in the digital systems controlling asynchronous electric drives are considered. The methodology for synthesizing predictors on the basis of neural networks is explained. An example of the synthesis of a numeral predictor for a closed control loop is considered.     

Determination of the fracture toughness of inhomogeneous three-layer fusion claddings on compact specimens

We propose a method for the evaluation of the fracture toughness (K _1C ) of multilayer fusion claddings on compact specimens at elevated temperatures (20, 70, and 300°C) with cladding (in the slot) of three layers of materials with gradually increasing crack resistance. As the testing temperature increases, the value of K _1C decreases for harder and stronger fusion claddings and, vise versa, increases for less strong and softer materials. __________ Translated from Fizyko-Khimichna Mekhanika Materialiv, Vol. 43, No. 3, pp. 121–122, May–June, 2007.     

Investigation of the Thermal Conductivity of Methanol–n-Hexanol Mutual Solutions at High Parameters of State

The thermal conductivity of methyl and normal hexyl alcohols and of methanol–n-hexanol solutions in wide ranges of temperature and pressure are measured in a facility implementing the regular regime method. The regularity of variation of the thermal conductivity of binary solutions with concentration is found.
