This 1---owleage *s utilized for the elimination of ac2ompanying elements. In the U case of the treatment of indlum solution!3 with zino amalgam, cop- per, thallium, ar-A oadmium are red-uoed to the metal and penetrate into the amalgam, whereas arsenic III and partly antimony, tellu- rium and selenium remain on the amalgam surface. The latter may lead to part of the inalum. goi%crrer into the amalgam. In oraer to remove arsenic V, which cannot be quantitativre3,y reduced dueLng treatment with zinc amalgam without causing a loss of indiim, the solution is treated with iron raduced in bydrogen and in a I+n sul- furic acid medium. During polarization itself, it is trae that also the presence of antimoP7, which m.,st filrst be -1.4moved, dis- Card 1/2 turbs.

Elektrokhimiya rastvorov i metallicheskikh sistem, 135-1-38 TEXT: The effect of zinc ions on the extraction degree of indium during cementation from a 1 and 0.1% H so soluiion was studied at different 2 4 temperatures (20 - 800C). 100 ml solution (100 mg/l In) with different ZnSO content and 20 ml zinc amalgam (500 mg Zn) were stirred vigorously 4 (1200-1300 r.p.m.) for 20 min in a water-heated cementation cell. Increased zinc concentrations in the solution were found to disturb the In extraction, especially in solutions of high H so concentration. The 2 4 potential of Zn amalgam shifts toward electropositive values. A tempera- ture rise supports the- extraction but cannot completely eliminate the Card S/850/62/009/000/007/012 Effect of zinc ions on the B117/B186 disturbing effect of zinc ions at higher concentration. A complete In extraction from weakly acid solutions is possible only after repeated treatment of the solution with fresh amalgam., If the solution contains an excess of cations (100-500 times-the amount of In) which are reduced by, zinc amalgam, it is recommended that hydrochloric or sulfuric solutions and NaCl be used for In.extraction. In this oase the extraction of indiums is not affected by zinc ions, and indium is reduced without overvoltage. There are 2 tables.

P. Bukhman (this paper,i 135-138). Results: The extraction of indium depends on the concentration of NaSO and Na S 0 At higher additive concentrations, larger amounts 4 2 2 3' of indium are extracted.' The concentration of zinc ions affects the reduction rate but not the amount of indium extracted., At a higher concentration of zinc ions the potential of zinc amalgam shifts toward electropositive values. Indium extraction depends semilogarithmically on the acidity of solution. The experiments show that Na SO and Na S 0 2 4 2 2 L---.Card. . 1/2 S/850 62/009/000/008/012 Cementation of indium from B111%186 under equal conditions, are more effective than sodium chloride additions when extracting indium from weakly acid solutions containing a large amount of zina.ions. Thus, only 80-85% indium was transferred into the amalgam by adding 100 g1l Nan, as compared to 96-97% by 1 g/l Na S 0 2 2 3' If acid solutions (H so > 1%) are used, the additives studied are less 2 4 effective. Phthalic acid in acid or weakly acid solutions does not affecti cementation. In neutral media, where it exists in the form of dissociate molecules, a slight increase in the degree of extraction was observed. The examinations confirmed the results of polarographic studies: During the reduction of indium, the above additives reduce the overpotential on the Hg electrode in sulfate solutions.

AN KazSSR, ser. energ., 1956, Nr 10, pp 114-118 ABSTRACT: Motion. of particles i-- a 2-phase axially symmetrical jet depends on the following: particle coordinates, their mass, their density, "Midel" cross- section, radius of the nozzle out of which the jet emerges, etc. However, this motion can be described with a much smaller mumber of dimeasionless com- plexeE, w1dch can be determined from the eqiation of particles motion and from the rate -of -dischar 'e formu-7ae.

Ser. energ. , 1956, Nr 11, pp 70-81 ABSTRACT: Results of the following are described: 1. Research on the laws governing the motion of particles in dust-air jets; 2. Theo- retical And experimental studies of the surface combustion rate and the surface temperatures of the coal particles; 3. Improve- ment in optic al-pyrometer photography methods of the direct measurement of the temperature of falling coal particles. On the basis of the experiments and computations performed it is shown that it is possible to make computations pertaining to the motion of coal-dust particles in an air stream by disregarding the change of particle mass and by considering the particles as spherical. Experiments consisted of measurement of particle velocities of gypsum and naphthalene of various sizes in an air Card I/?- stream issuing from a nozzle. The velocity of the particles SOV/124-58-4-3798 Research on Combustion Processes (cont. was determined by the stroboscopic method. The determination of the tem- perature and rate of combustion of coal particles was performed in an installation consisting of a combustion chamber equipped with an observa- tion window, a feeder for the particles, and a photographic camera fitted with color filters. The rate of combustion of the particles was determined by the change in weight resulting from the combustion during the transit of the particles through the chamber. The temperatures of the particles were determined by the method of optical pyrometry as follows: The burning particles flying through the chamber were photographed through two color If ilters together with the pyrometer filament heated to a certain temperature; photos were taken at different exposures. Experiments with combustion of electrode carbon have shown that the surface rate of particle combustion, as well as the surface temperatures, are in good agreement with the values received from computations based on the theory of the heat balance of com- bustion. The feasibility of the direct measurement of the temperature of burning particles by the method of optical- pyromete r photography has also been demonstrated. 1. Coal--Combustion 2.

The*temperiature of-heat carrier (distilled water) in the operational section of the heat exchangetube varied from 11.8 to 500C; the temperature of the internal surface of the tube varied from 34 to 1100C in various experiments. The tube was heated by electric current. Since the tube resistance was constant ove 'r.its length, heat emission per unit length was also constant, which was confirmed by a linear temperature distribution along the heat exchanger. In determining the temperature of the internal tube surface, temperature drop in the'radial direction was taken Into account.

AN KazSSR, Ser. energ.", 1961, no. 1(19) 21 - 29, Kaz. sum- mary) TEXT: The authors analyze the effect of the channel geometry (the correla- tion of radii of the external and internal pipes forming the channel). According to the calculation performed, the channel geometry exerts a substantial effect upon the temperature field, heat exchange and the very flow. The asymmetry of the temperature profile, in particular, the location of the temperature maximum, depends on the ratio of the radii. The same dependence is characteristic of the number Nu in stabilized heat exchange, which. in general, is determined by two parameters, i.e. the ratio of the radii and the ratio of heat flows through the channel walls. An evaluation of heat emission, separately performed for the internal and external wall of the ring-shaped channel, shows that in the former Card 1/2 Investigating the... S/137/62/000/006/007/163 Aoo6/Aioi the heat emission is more intensified, in particular, at a high ratio of the ex- ternal and internal pipe radii of the ring-shaped channel. The calculations per- formed (for the case of constant heat flows through the channel walls) show that the location of the temperature maximum depends only slightly on the rate profile. The effect of the latter upon heat emission is evidently of the same nature as for heat exchange In two extremal cases, namely a round pipe and a flat channel. V.
