Abstract: FIELD: measurement technology. SUBSTANCE: device has semiconductor membrane, which has stiffening ribs on its ends. The first dielectric layer is applied onto the face side of the membrane. Thin-film heat resistor with film conductors is formed above the layer. The second dielectric layer is applied onto these elements. Gas-sensitive thin-film resistor is formed onto the second layer of dielectric, as well as supply conductors. Moreover, film catalyst is formed above gas-sensitive thin-film resistor. Two film supply conductors of heat thin-film resistor are connected with circuit for controlling heat thin-film resistor. Two supply conductors of gas-sensitive thin-film resistor are connected with measuring bridge, which has three resistors, one which is connected to voltage divider together, with gas-sensitive resistor and two others are connected with reference frequency divider. Both dividers have common points of supply, which are connected to the bridge through current limiter. Diagonal of the bridge (average points of voltage divider) is connected to inputs of amplifier, which has output connected to indicator. Measuring bridge is formed above the second dielectric layer, in such a manner, that all three its resistors have to be thin-film resistors, made together with gas-sensitive thin-film resistors of the same material, and has the same sizes. Film catalyst is applied upon the resistors, made of the same material and having the same sizes as the catalyst in gas-sensitive resistor. Three resistors of the bridge are located onto heat thin-film resistor onto the second dielectric layer. Resistors of the bridge are closed by gas-proof mask, made in form of rectangular film, which has a window, coinciding the topology of gas-sensitive thin-film resistor, disposed above the latter one.

IPC: C22B1/216
Filed: 1991-10-31
Granted: 1995-01-09
Abstract: FIELD: ferrous metallurgy. SUBSTANCE: method for drying finely divided concentrate in rotating drums includes feed of main bulk of concentrate into two-layer flow of hot gases. Two-layer flow is formed of central high-temperature flow of combustion products and encircling flow of diluting air; and stabilization of temperature potential along the drum length by regulated mixing of combustion products with separately supply of diluting air. When concentrate contain 40-50% of fine particles sizing 0.01-0.10 mm during the first time period equalling 0.03-0.08 of the total time of concentrate treatment in drum, the temperature of the central part of the two-layer flow is maintained constant and equal to the temperature of combustion products at drum inlet by supplying to it the diluting air at rate equalling 1.4-1.5 rate of supply of combustion products. When the content of fine particles in concentrate reduces from 40% by every 10%, rate of supply of diluting air is reduced from 1.4 by 0.08-.10 of rate of supply of combustion products into drum. EFFECT: improved quality of product and intensified process.
