Khimiya i khimicheakaya tekhnologiya, 1958, Nr 3, pp 93 - 99 (USSR) ABSTRAM At present, asdium sulfate is reduced by solid reducing agents at 850 - 1100 . The main mass of the sulfate is reduced in the melt. Its reduction is, however, also Possible at temperatures considerably below the melting point. The sodium sulfide formed can form a eutectic with the sulfate, the melting point of which is at 650 - 7500. Thus, the liquid phase, which under certain conditions promotes the acceleration of the process, can also be obtained at lower temperatures. The decrease in temperature of the sulfate reduction can be of great practical importancet a) For saving fuel. b) For decreasing foreign additions, and a) For increasing the life of the refractory material in the reaction furnaces. The optimum temperatures of the reduction Card 1/3 process can be chosen on the basis of thermographic investi- Thermographic Investigation of the Reduction SC)V/153-58-3-17/30 Process of Sodium Sulfate gations. The problem of the initial temperatures of the sulfate reduction by pit coal remained unexplained, apart from single hints at working conditions (Refs 6 - 8). The thermographic method of deteiudhing the baghvh*g of the Na2 so 4 reduction process applied by the authors makes the clarifi- cation of the effect of the degree of dispersion upon the temperatures mentioned with sufficient accuracy possible. The self-levelling mirror galvanometer of the type 11YI 11, system A. V. Ulitovskiy was used for the measurement of the temperature difference in the sample. Based on the results obtained, the authors arrive at the following conclusions: I.-The thermographically determined temperature of the beghrdngreduction of sodium sulfate waBs a) through the coal of the type is, A:61rt4t~_" 760', b) through coal of the type " *k" it wa a 720'.

Khimiya i khimicheskayp. Vekhnologiya, 1958, Nr 5P' pp 61-64 (USSR) A13STRACT: As most substances are too ex-oensive (some gases) for the red-action of sodium sulfate to the sulfide, or their 'use is connected with difficulties concerning the apparatus employed, the least expensive suitable substance for thig purpose - Peat - is interesting. Its deposits are found in many areas of the USSR. The difficulties hitherto existing in the utilization of peat for this purpose were the fact that peat as the lighter substance appeared on the surface of the mass and burned. When briquetting the charge this process should be excluded. Although the organic substance in peat contains abcut 56% carbon and 7% hydrogen' (Ref 5) the whole carbon can be used in the Na SO reduction, due to high yields of volatile 2 4 componentso The s,e ---%%a1at1V1e components as a whole consist of Card 1/4 H21 CH 4 and CO and could act as reducing agents themsel'ieso .-OV/1 53-58-5-10/28 On the Problem of the Reduction of Sodium Sulfate by Peat The problem is made more complicated by the relative low temperature of peat pyrolysis. Taking into account that H 2 and CH4 contents in volatile gases of peat increase at higher temperatures, and that the beginning of I~he Na2so4 reduction by H2 and CH4 is at 500-5500, it, may be maintained that part of the volatile substances is utilized in the reduction process. With peats from deep moors a certain increase of the DyrolysiB temperature may be expected (Ref 8). As there are no data in publications the present special investigation was carried out, Figure 1 shows the experimental results (I series) which were to explain the effect of the peat mass upon the completeness of the reduction of sodium sulfate. The experiments were carried out in a nitrogen atmosphere. The curves obtained (FIR 1) show a maximum dependent upon the peat mass in the charge, and which corresponds to the ratio of the weights of peal": sulfate = 1 : 196. With a larger amount of peat the thermal co-ductivity of the briquette is expected to decrease Card 2/4 rapidly. This will cause the rate of the process to decrease, SOV/', I U/26 On the Problem of the Reduction of Sod-ium Sulfa-.e by Peat as the reactions themselves require heat addition. Curves of figure 2 show the results of the comparative experiments with peat and coal as reducing agents (II series). The rate of the reduction by peat is at 750 and 8000 considerably higher than by coal (anthracite). Since under the conditions of practical work always d certain amount of air enters the reaction space the above-mentioned regularities may ohange there. Figure 3 shows results of the ex-oeriment with a certain amount of air penetrating to the briquettes (at a ratio of Na so . peat 2 4 2-4). The degree of reduction was then lower than without oxygen entering.. From the curves in figures 2 and 3 it may be oeen that oxygen additirn has a hieher influence upon the reduction of peat than of coal. From all experiments it may be seen that inspite of the high degree of reduction no melting of the b::iquettes occurs if the amount of peat does not exceed 1-6 g per 1 g Na 2so 4* Mixtures from pit coal and peat or another 3ubstarce with a higher yield of volatile substances than of coal woi~ld offer good prospects.

The authors investigated methods for the utiliza- tion of waste water of the productions ofrinaphthylamine and the dye "Par Black" (mekhovcy ohernyy)g with a view to utilizing the sulfur as quantitatively as possible without appreciable amounts escaping into the atmosphere. Sodium salts of various sulfur-containing aoids which can be transformed to sodium sulfite are contained in the above-mentioned waste water. Organic compounds contained in these waste decompose at the tempera- turee employed for the reduction (850-11000C), so that contamination of the Card 1/4 4 Utilization of Sodium Thiosulfate S/153J60/003/02/21/034 in Waste Water of Several Plants B011/B006 reaction product does not occur. The decomposition products also have a re- ducing effect and lower the amount of reducing agent required. The authors used several samples of thiosulfate (the term used to dsaote the evaporated waste water residues). The analytical data of these samples*are given in Table 1. Anthrazite was applied as reducing agent, Both the thiorulfate and coal were finely- ground. The tests were carried out in dry N atmosphere whj(h was free of oxygen '~ The authors found that the thermal treatment of sodium thiosulf ate from waste water of the above-mentioned plantB is possible with- out losing appreciable amounts of sulfur due to vaporization. The effect of the temperature on the reduction of thioaulfate from the-c-naphthylamine production is illustrated in Table 2. Sodium sulfide formation increases somewhat with a rise in temperature. Sulfur losses during reduction amount to about 54. Polysulfides are largely decomposed at reduction temperatures, as was proved by the authors, experiments using anthracite at 75VOC (see Fig. On P~326). For reduction of thiosulfates containing no basic substancoo, it is adviced to admix the charge with industrial soda or caustic soda. Basic waste water is particulary suitable for this purpose. Reduction data of thiosulfate containing admixtures (NaOH, Na.co 3 , NaCl) are shown in Card 2/4 Utilization of Sodium Thiosulfate S/153/60/00'3/6~/21/034 in Waste Water of Several Plants B011/BOU6 Table 4. An admixture of the two firet-mentioned substanoes rapidly inorea- sea the formation of sulfide sulfur and considerably decrease vaporization losses of sulfur, PartioularlYr-t 85000- NaCl does not promote sulfide for- mation, but accelerates the melting process., and reduces sulfur losses by about 1/2. In Table 5, the reduction data of a 10 mixture of the thio- sulfates from the waste of the two first-mentioned plants are listed. This procedure increased the yield of sulfur. on reducing thiosulfate with coal, sodium polysulfides are hardly contained in the melt. The decomposition occurs during the reduction and is all the more complete, the higher the temperature and the longer the time of reduction. The authors mention R. I. Levenzon, V. V. Kafarov, Ya. S.

Since the equilibrium in the reaction CO 2 + C'-*_2C0 (4) at reduction temperatures *f 850-1,1000C ia ehifted into the direction of the carbon monoxide formation, the possibility of the reduction of scdium sulfate according to Equation (3) is not exclud- ed.

The specimen is fixed in the machine clamping device. The deformation is effected by the upper clamp connected to an electromotor. The lower clamp is fastened on a force-measuring spring-mounted lever. The stress on the lever is produced by a measuring spring. In changing the spring It is possible to obtain the necessary stress diagram scale. It takes about 10 seconds to obtain the complete tension diagram, A pen records the results on a paper tape fixed to a drum which is put into operation during the motion of the measuring spring. G.

The metals studied were conductivity copper, chemically pure silver and cadmium. Test specimens of copper were 92.2 mm long and 1,,314 mm thick. Specimens of cadmium were 100 mm. long and 1.64-1 mm thick, while '-hose of silver were 100 mm long and 1.409 mm thick. Before testing the copper specimens were annealed in vacuum at 4~00 OG for 3 hours. Cadmium was annealed -in water at 100 OC for 3 hours and 40 minutes. Silver was annealed in air at 400 OG for 3 hours. All samDles wer;~ extended at a constant rate of 0.8 mm/sec on a special machine and the extension and load were automatically recorded. During deformation the specimen temperatitre Card was measured with a copper-constantan thermocouple as a function of time, using the electronic potentiometer 115 EPP-09"".

Fig 5 shows the ratio of the energy abso-t-bed -to the work of deformation as a function of exten5inn; again curves 1, 2 and 3 represent coppers silver and cadmium respectively. The author draws the following conclusions from his results: (1) For the same degrep -,f deformation the energy absorbed in straining coppe*-:--, silver and cadmium is of the same order as the energy absorbed during their compression. (2) Since there 1E no friction at the clamps in extension tests and consequently no heat loss due to friction, the t,~ark of deformation per one g of metal Is smaller in extens-11.on tests than in compression. It follows that the iatic; the energy absorbed to the work of deformation is greatt.ez in straining than in compression. (3) At the initial stages of deformation the ratio of the energy absorbed to tho work of doformation is vory largo because a large portion of the work of deformation Is used to increase Card the internal energy of the metal; with increase in the 4/5 degree of deformation this ratio falls, first rapidly and then more slowly. (4) Before rupture a quasi.- saturation state occurs which is shown as the curvatui-e SOV/126-- -7-55-24/25 Absorption of Energy on Plastic Extension of a Metal of the ends of the curves of energy absorbed (Fig 4); this is due to the fact that at rupture the energy is absorbed mainly in the "neck" portion.

It is, therefore, natural to suggest that changes in the properties of a metal in the process of plastic deformation will be connected in some way with this quantity. The number of papers published on this topic is very limited. Kunin (Ref 1) has found that in the case of copper the change in the absolute thermal e.m.f. is directly proportional to the energy absorbed by the metal. Other workers have found (Ref 2) that the specific electrical resistance for cadmium and lead deformed at low temperature increases linearly with the latent deformation energy. The present work describes the results of measurement of the absorbed energy, Card 1/11 induced thermal e.,m. f . and the change in the specific 66887 Measurement of the Specific Electrical Metal Card 2/4 SOV/126-8-1--3/25 Internal Energy, the Thermal e.in.f- and the Resistance During Plastic Deformation of a electrical, resistance during the plastic deformation process,, Experiments were carried out on a set of specimens made of copper and chemically pure silver and deformed under identical conditions. The method of measuring the absorbed energy was described by Kunin in Ref 3. The thermal e,,m,f. and the specific electrical resistance were measured as followsg the initial length of the specimen was 100 mm and the initial diameter was 1.314 mm for copper and 1.4og mm for silver specimens. The deformation was carried out using the machine described by Kunin in Ref It and at the same rate as before. The form of the specimens is shown in Fig 1. Each specimen cons�sted of a deformed (A) and an undeformed (B) section. Thus the thermal e.m~f., of the deformed metal was measured relative to an identical undeformed metal. The vessel I contained kerosene and the vessel 2 a mixture of ice and water. The thermal e.m.f. was measured using a mirror galvanometer of type DI-25. The galvanometer could be calibrated using the voltage LK 66887 SOV/126-8-1-3/25 Measurement of the Internal Energy, the Thermal e.m.f. and the Specific Electrical Resistance During Plastic Deformation of a Metal divider shown on the right-hand side of Fig I. It could also be used to back-off the thermal e.m.f. The sensitivity was 0.0218 mV/mm and 0.00666 mV/mm depending on whether the thermal e.m.f. was measured directly, i.e. by measuring the deflection of the galvanometer, or whether it was measured by the compensation method. Fig 2 shows the induced thermal e.m.f. in mV/deg as a-function 'of th6 absorbed energy (in cal/g) for silver. As can be seen, the relationship is linear. A similar result was obtained for copper. The slopes are 0.41 mV.g/cal.grad for silver and 0.086 mV.g/cal.grad for copper. The specific electrical resistance was measured using the circuit shown in Fig 3. The resistance was measured while the specimen was held in the machine holders 1 and 2 and was compared with the standard resistance R The relation between the absorbed energy (cal/g? and the relative change in the specific electrical resistance for copper is sho,,m in Fig 4.

TITLE4~ An apparatus for the electrodeless measurement of electrical conductivity PERIODICALs Pribory i tekhnika eksperimenta, no.6~ 1961, 111--113 TEXT: The device described is based on the measurement of the interaction between currents induced in the specimen by a moving magnetic field with the field itself. The non-uniform magnetic field is produced by a 12-pole rotating electromagnet 1 (Fig.1), which is kept in rotation by the induction motor 2, The diameter of the magnet is 420 mm, the number of revolutions is 2180 rpm and the pole gap is 30 mm. The magnetic field is produced by two coils (main and auxiliary). The main coil is supplied by the rectifier 3 and the current through it i5 adjusted manually, The auxiliary coil is supplied by the rectifier 4 and is adjusted automatically so that the drag on the standard specimen remains constant. The standard specimen is made of constantan or manganese and is suspended from the Card 1/ 3 An apparatus for the electrodeless... 5/12o/61/000/006/023/041 E032/E114 balance 5. The balance is in equilibrium if the dragging force is equal to the weight of the standard specimen minus the load at the other end of the balance. The latter carries an opaque diaphragm screen 6 with a wedge-shaped aperture cut in Lt. The di-aphragm is located between thirteen scrie,-i-connected thermocouples (copper-constantan) and a lamp. When the balance is in equilibrium the thermocouples are uniformly illuminated and there is no current in the thermocouple circuit, As soon as the equilibrium is disturbed a current appears. It is amplified by the amplifier 7, and the output of the latter operates the motor 8 which in turn adjusts the output of the rectifier 4, The specimen under investigation is suspended from the balance 9 at the centre of the magnet gap, It was found that the dragging force is directly proportional to the field strength and the angular velocity of the magnet. The electrical conductivity can be measured with an accuracy of 0,01% (relative to the standard specimen).

The recorded diagrams of the tension and relaxation curves are 490-500 mm with the maximum error not exceeding 0-5 %. The diagram scale may be varied between 1:100 and 1;1 along the deformation axis and between 0.02 and 0.5 kg/mm per mm diagram along the load axis. The machine is schematically shown in F3.g. 1. The deformation mechanism consists of the 0.25-kw asynchronous three-phase motor 1, the gearbox 2 with the shaft 6 and the electromagnetic clutches 7, the transmission shaft 3, worm gear 9, nut 4, and screw 5. The gear ratio may be varied between 1:1 and 1:10,000, The electromagnetic clutch 8 is used for engaging the gear ratio 1:1.

The electron conductivity of the gas is calculated by using Drude's me- thod and considering.the drift of electrons in determining their travel time. The following are.given: free electron concentration, the mean effective cross section of their collisions and their mean free path. It is assumed that these quantities have a spatially isotropic distribution in the gas and are independent of time. It is further assumed that the macroscopic parameters for the state of the gas are given. The con- ductivity problem reduces to finding the mean drift rate of the electrons. It is shown that kinematic relationships may be used for determining conductivity without knowing the distribution function. A model is set up in which a gas particle is sur- rounded by a sphere of given radius. Free electrons within this sphere drift under .the effect of a field which is parallel to the axis and where the electrons are scat- 1/2 L 26628-66 ACC NR, APbUI391U tered by a particle. After scattering, the electrons travel in the field along curved Y trajectories resulting in electron-ion and electron-molecule collisions. Since mole- cules and ions have large masses, their 7;c, motion in a weak field does not depend on field intensity. Therefore the mo- tion of electrons is limited only by the surface of the sphere. In the cc case of weak fields, it may be assum- A ed that electron scattering intensity vc=#J_~ is nearly equal in all directione. An expression is given for calculating the electron drift rate within a given sphere. An improved classic- al formula for calculating conductivity is given? Orig. art. has: 1 figure, 12 formulas.

These, in turn, are divided into their organic economic regions (units). The analysis of geographical features predoainat_-~ in. book, although the first part also providee.Uie reader with an historizal-background. The industries of this Republic have developed along the railways, the rivers and the coast, with 40 per cent of the manufacturing located at Ashkhabad, the capital. The only exceptions to this rule are the sulphur mines and plant at Sermyy ZAvod and-7 Darvaza, in them middle of the Karakumy desert. Kara-Bogaz-Gol enterprises strip mirabilite (glauber salt) from the bottom of evaporated marshy lakes, but the development of local industries is hampered by lack of fresh water. Another group of industries along the Caspian shore comprises Cheleken iodine, bromine, ocher, and oil and ozocerite enter- prises. The oil and natural gas region is located mainly south of the Krasnovodsk-Ashkhabad railway. Card Twrkmen SSR; Economic and (Cont.) Gall No: None given The petroleum industry of the Republic shows marked progress and oil derricks, scattered in the barren desert) are steadily growing in number; Nebit-Dag is the Turkmen oil capital. In 1956 the Republic produced 3,430,000 tons of oil. A pipeline leads from Vyshka to the Krasnovodsk refinery; a natural gas pipeline to Krasnovodsk is under construction. During the earthquake of 1948, the worst in Turkmen history, Ashkhabad's industrial enterprises, administrative-and residential build- ings and railway station were destroyed. The earthquake'elaimed thousands of vl6tims-. The restbration of*the cityls'industrial enter- prises is described-to some extent. To-day the city numb'ers 142,000 inhabitants.

The city pro- duces silkt cotton textile, shoes, and me at products. Tables show areas under crop cultivation, with special emphasis on cotton;: the irrigation network is being expanded. Cotton grows in the area of Chardzhou and along the Murgab River. Sheep and dromedars are included in animal husbandry. Host electricity (94.5 per cent) come from oil-burning steam- power stations, although the book mentions a series of hydro- electric installations on the Murgab River.

PERIODICAL: Fizika Metallov i Metallovedeniye, 1957, Vol-5, No.1, pp. 173-174 (USSR) ABSTRACT: The reversibility of elastic deformation and of thermal expansion permits considering the simultaneous effect of these phenomena on the basis of generally valid thermo- dynamic relations. Khvollson, 0. D. (Ref.1) derived the following formula inter-relating the coefficient thermal expansion a with the applied stress: (tx ( D) ')T - E2 -p where E is the Young modulus and T is the temperature of the deformed substance. For a given temperature the right-hand side of this equation is constant and by integration the following linear dependence is obtained Card 1/4 between the coefficient of thermal expansion and the 126-1-30/40 Influence of the stresses on the thermal expansion of a deformed metal. stress: U. = CXO + C Cr (2) a being the coefficient of linear expansion in absence d stresses. Rosenfield, A.K. and Averbach, B.L.(Ref.2') discovered a jump-like deviation of the coefficient of expansion a from linearity when passing through the limit of elasticity. The experiments were carried out with three grades of steel and two grades of invar. The change of the coefficient of expansion (x, caused by the plastic deformation,was the residual one. After removing the stress', the coefficient of expansion had another value differing from the original value. These authors did not consider the important problem on whether Eq.(2) is valid for work hardened metal. It is known that the limit of elasticity of a metal which is subjected to plastic deformat-ion increases to a value corresponding to the applied load provided that the temperature of deformation is sufficiently low and that no relaxation effects take place. As a result of -that, Card 2/4 repeated deformation of a preliminarily work hardened 126-1-30/40 Influence ofthe stresses on the thermal expansion of a deformed metal. metal up to loads corresponding to the new limit of elasticity are reversible and Eq.(2) should be fulfilled. Thereby the values of ot and c should become different to some extent owing to the changes caused by the plastic deformations. Independently of the work of Rosenfield and Averbach and approximately at the same time the authors of this paper mea3ured the coefficient of linear expansion of copper under load. The copper was subjected to considerable preliminary work hardening. Special measuring equipment enabled measurement of the coefficient a with an accuracy of up to 0.2 to 0.3%; the thermal expansio.u was effected in the temperature range 14.98 to 41.48uC. The elongation as a result of the load and the thermal expansion was measured bZ optical means an the results are graphed in Fig.1 (10--' q/uC vs. a,kG/mm 0 It can be seen that within the limits of the here mentioned accuracy of the experiments, the coefficient of thermal expansion increases linearly with increasing stresses in accordance with Eq.(2). Since during work hardening the Young modulus E remains practically Card 3/4 unchanr,-ed, it follows from Eq.(l) that the changes in a C~ 0 126-1-30/40 Influence of the stresses on the thermal expansion of a deformed metal. and c during work hardening are due to a temperatule dependence of the Young modulus. In conclusion it is pointed out t-hat the problem of therwal expaiision of loaded metals is of great practical importance, particularly from the point of view of the theory of tolerances and settings.
