Abstract: [Author's English summary] The different forms of esophagus stenoses are classified on the basis of nearly 500 examinations. Inflammations due to non-alkaline causes are described with special reference to their X-ray pictures thus facilitating their differentia- tion from tumors. The differentiation between infiltrative tumors of the abdominal tract of the esophagus and the cardiospasms as well as the recognition of cancer developed from alkaline stenosis is fully treated. The majority of the cases discussed by the author have been verified by surgery and histological examinations. All Western refer-~-- ences, FOGEL, Mariag Dr. Dr. Gaza Molnar.

The changer, in flux accompanying the jumps ranged from 1 x 10-?- to 4 G-cm:2, and the jump durations ranged from 2 x 10-11 to 5 x 10-4 see. Each Jump is connected with a partial penetration of the flux into the super-,f conductor. The relation between the jumps and the critical fields of the super- Card L 5354-66 ACCESSION NR- AP5021105 conductor is discussed js as are various factora governing the magnitudes and dura- tions of the jumps. It is concluded that the experimental data do not show con- 'clusively whether the obBerved flux jumps are associated with the existenceof ia-. dividual regions of superconductivity with different parameters, or whether they f are connected with some macroscopic processes which limit the rate of phase transi.' tion.

The octupole-octupole in- -group, aiul the value 0.2 fort teraction was also assumed to be constant within each of these two groups; the in- teraction constant was so chosen as to give the Wat agreerrant with the expertmon- ,tal energies of the 0- states. The first two roots of the secular equation were .calculated for the G-jl-, 2-, and 3- states, and the energy values, together with the energies of the first and second bands and the corresponding experimental data (when available) are presented graphically. The calculated values of the energies of the lowest, l-, 2-, and 3- states Agree well with the experimental values, pro- vided the effect of blocking is taken into account when it is important. 7he octu- pole-octupole interactions are usually- important for I- ani 2~ states, and are usu- ally negligible for 3- states. The structures of the octupole states are illustra- ted by tabulating the contributions of the various two-quasiparticle statc3 for a number of selectedt nuclei. In most nuclei the lowest 0- state is strongly collecti- vized, whereas the I- and 2- states may be collectivized but are usually r.ither .close to two-quasiparticle states. The 3- states may be regarded as two-quasipar- ticle states with less than 1% admixture of other than the principal state. Re- duced electromagnetic transition probabilities were calculated, and a.future paper is promised in which these will be discussed.

Results were realized in the area of spherical nuclei where energy states and probability of electromagnetic transitions were computed. It was found that re- search in the area of strongly deformed nuclei is limited, but basic' equations are cited and the question of excluding the heated state is studied. Based on the method of approxima-e second quantization in limits of superfluid models of the nue , energies leus were calcu- lated for octupole collective states with IJLK =1 - 0 of even-even 'Card 1/2 ACCESSION NR: AP4010752 strongly deformed nuclei in areas of 15~,g k6 186 and 2286 A::5254. The behavior of collective octupole state energy with K7r=.O is ex- plained by introducing one new constantJt ; all remaining parameters are specified earlier. Microscopic treatment of tbe-state based on the superfluid model of the nucleus differs strongly rrom the phenomenological treatment of the unified model of the nucleus. According to the treatment of the superfluld nucleus model, the octupole states in single nualei'are relatively low (lower than tP and Tof vibration state I s), and possess clearly expressed collec ive properties, but in other nuclei such states have high energy values and are inherently similar to quasi-partlele excitation states.

Results: T' - 15 - 20 min; optimum A concentration 20 g/liter. B and the stage II sulfate solution containing 20 - 25 g/liter of A pass continuously into oximator 1 (Fig. 1) of stage I. The resulting mixture is passed into 2, where it is neutralized with gaseous NH 3* The bottom layer in separator 3, spent sulfate solution, is passed into an evaporator, the upper one (Oxime solution and B) into collector 4, and thence into stage II oximator 5, where it is mixed with a new A solution. NH3 is used in the stage II neutralizer 6. The upper oxime layer in separator 7 passes to the next stage, and the sulfate solution passes via collector 8 into oximator 1.

Nr. AT6ooo475 This divergence can be explained only by profound changes occuring in the fine structure of the glasses during solution in HF. A study of the pro- cesses of dissolution and crystallization of lithia-silica glasses revealed that the formation and subsequent behavior of drop-shaped microphaaes in the glass cannot be described by purely statistical relationships3 if this were the case., then as the bulk composition of the glass changed, the com- position of the microphases would also change statistically. This does not take place, however, the bulk composition corresponds to definite chemical ecimpounds., and the transition from one compound to another takes place in discontinuous fashion. Primary and secondary phase-separation processes are discussed.

TITLEt Investigating the Thermal Conditions of Vulcanization of Heavy Rub- ber Articles by the Method of Electrical Modeling Iq PERIODICAL: Kauchuk I rezina, 1960,~No. 10, pp. 23 - 29 TEXI!t The author recommends the method of electrical modeling for investi- gating the vulcanization conditions of compact rubber articles, which does not require thermal measurements. Thermal measurements are labor- and time consunbg and do not give accurate results due to distorted temperature showings of the hot junctions in the thermocouples used. According to the authors, electrical models are conveniently used for studying the processes of heat exchange in various in- dustries and in the rubber industry in particular. It is stated that the physi- cal processes of the actual body can be modeled if the mathematical description of these processes in both the actual body and the model are the same. This is the case for thermal conductivity and current distribution in a circuit withdls- tributed resistances and capacitances. It is shown that the heat conductivity processes can be modelled by the electrical analog method, i.e., the change in Card 1/9 89062 3/138/60/000/010/004/008 A051/AO29 Investigating the Thermal Conditions of Vulcanization of Heavy Rubber Articles by the Method of Electrical Mcdeling time and space of the teraperature in the actual body can be evaluated from the change in the voltagesU relative to time and space of the model (Refs. 1, 2). An example Is givent for a uniform heat flow, the specific heat flow is determined according to Fourier's law: q - -Adt (1), where % is the heat-conduating co- efficient In kcallm - h - OCI dt 9% nt in OC/m.

It is pointed out that Equations 1 and 2 and also 3 and 4 are only different in nomenclature of the physical values, but are the saw from the mathematical point of view. In order to make this type of comparisons 1) the initial temperature and voltage distri- bution must be the same, 2) the change of the temperatures and voltages at the boundary lines of the bodies must comply to the same law (Fig. 1), 3) the ratio of the experiment duration on the model T2 to the duration of heating and cooling of the actual body,%j, must not be selected arbitrarily, but based on the equal- ity of the similarity criteria, which characterize the processes of thermal con- ductivity and electricity distribution in the circuit, having distributed resist- at ai., ~ and capacitances (i.e., Fourier's criterion).

There are no auxilliary at- tachments, its area is 2 M2, the cost about 5,000 rubles. It is suggested that the BC (rOCT 2825-55) - VS (GOST 2825-55) type wireless carbon resistances be connected to each grid, produced with 100 to 910 kohm for an operating voltage of 350 v and hermetically sealed thermo-resistant paper capacitors of the BrT (BGT) type with a rated maximum capacitance of 10 Pf for a workinS voltage of 200 v d-a be used az the ~;apacitanoes. In assembling the grid, special attention should be given to th-e distribution uniformity of the resistances and capacitwxms along the. joints. As source of direct current the author recommends using eitlier the 70-AMqr-5 rOCT 7534-55 (70-AMTsG-5 GOST 7534-55) type "Druzhba" battery or the alkaline cadmium-nickel battery of the 64-AP-2,25 (64-AKN-2.25) type or the BCA-III (VSA-III) type selenium rectifier with a filter made of a choke and two capacitors for smoothing down the pulsations of the rectified voltage. All recommended sources yield a voltage Of 6"0 - 80 v. D-c from the source is f, e: 7to two voltage dividers in the form of sliding wire rheostats with a resistance of 5,000 ohms. Portable multi-limit magneto-electrical d-c volt-meters are suggest- ed for measuring the voltages at the dividers, viz., the M-106/1 (M-106/1) type Card 5/9 89062 S/138/60/000/010/004/008 A051/AO29 Investigating the Tbermal Conditions of Vulcanization of Heavy Rubber Articles by the Method of Electrical Modeling of 0.2 class, where for 75 v the value of one division of the mirror scale is 0.5 v. The C-95 (rOCT 1845-502) - S-95 (oosr 1845-52) type electrostatic voltme- ter is suggested for meaturing the voltages in the points of the lattice. The voltage range is selected depending on the voltage of the energy source and the magnitude of the scale of electro-measuring Instruments expressed by the formu- la: Mu - (U - Uo)/Ikt - to), and never exceeding: 75 = 0.47, where 75 v is the 160 scale of the electrostatic voltmeter and 1600C is the maximum temperature in the vulcanization of casings. The initial condition of the heating process of the compact rubber articles is usually t1he uniform distribution of temperature, to const, which correBponds to the initial voltage of the model, Uo = 0. Thus, the temperature field In the actual body can be determined according to the distri- bution of the voltages in the model, i.e., t = to + -U (8). Calibrating ex- I WU_ periments on a simplified electrointegrator YM30-1 (UMEI 1) conducted with known exact analytical solutions of the temperature field equation in the plate showed that the discrepancy in determining the temperatures using the electrical model Card 6/9 P A051/AO29 Investigatin~g the Thermal Conditi ons of Vulcanization of Heavy Rubber Articles by the Method of Electrical Modeling method did'not exceed 1.5 + 2~.

A spherical bicalorimeter (Fig. 1) was used for investigating the heat-conduc- tivity. This is a metal.aphere surrounded by a thin spherical layer of the investigated liquid. Under regular conditions the difference of the temper- atures of the thermostat medium and the center of the bicalorimeter is ex- pressed by the formula: tf - t - (tf.-to)e-mz or ln(tf-t) ln(tf-to) ml: (1), Card 1/7 20865 S113 61/000/003/005/006 The effect of the gelatinization process of...

Figure 2 shows the relationship of ln(tf-t) to the duration of the heating. The coefficient of the heat-conductivity of the liquid ;4 is determined from the formula: 12 1 where 1 = Di/D2 is the rELtiO of the internal and external diameters of the bicalorimeter; Cjrj - the thermal capacity of the metal sphere; Cr - the volumetric thermal capacity of the investigated liquid. In the experiments the method of regular heating of the bicalorimeter was supplemented by the method of stationary internal heating of the sphere, inside of which a heater was placed. For the case of stationary heating of the double-layer sphere, the heat conductivity coefficient is expressed by aver.*4 (3a)- Faver.-At The quantity of heat transmitted through the layer (Q tatio ar ) was deter- mined from the expenditure of electric energy by the Rea eK ~he method of Card 2/7 20865 B113 6,1/000/003/005/006 The effect of the gelatinization process of ... A051 YA129 regular conditions was used to determine-the relationship-~ of the latexes and the gelatinizing mixtures to the temperature,and the scationary condi- tions method was used for determining the kinetics of the "change during the gelatinization process and that of syneresie. In order to determine the effect of gelatinization on the heat-conductivity, the kinetics of the tem- perature change relationship to the heat-conductivity was investigated both for revertex and latex L-7 (Figs- 3t 4)- It was noted that immediately after gelatinizing agents are introduced into the latex mixture, processes occur causing a decrease in the heat-conductivity of the system. Th~R results ob- tained showed that after.the system has reached a certain degree of stabili- t;~ even before the formation of a solid gel.,. structures are formed in it gradually, which sharply limit its mobility in certain sections, hampering convection, diffusion and heat-exohange and thus.decreasing the heat-conduc- tivity. The change of,the latter and.that of the electro-conductivity does not.stop after'.the formation of the solid gel: both the electric resistance VYN and the heat-conductivity intrease. The heat-conductivity was measured when the discharging liquid was removed from the system, in order to determine the effect of the syneresis on the thermal-conductivity (Fig. 6). it is pointed out that the change both in the heat-conductivity,as well as that of Card 3/7 20865 S/138/61/000/003/00VO06 The effect of the gelatinization process of....

For industrial processes in the temperature range 250 to 3000C, normal mineral oils and glycerine are of inadequate thermal stability, whereas molten salts are only suitable for temperatures above 3850C. None of the existing heat transfer media adequately covers the range 250 to 3000C. New types of fluid being developed for this application in the USSR and abroad include hydrocarbons of the diphenylmethane series which are synthesized in the USSR and aromatic oils such as mobiltherm 6oo. The hydrocarbon of the diphenylmethane series of the greatest thermal stability is ditolylmethane, the principal Card 1A 23424 S/094/61/000/008/002/003 Liquid ditolylmethane E194/F.484 physical characteristics of which are given in Table 2. In order to investigate the problems associated with the application of liquid ditolylmethane, the Moscow Institute of Fine Chemical Technology imeni Lomonosov (Moskovskiy institut tonkoy khimicheskoy tekhnologii imeni Lomonosova) made a pilot heat transfer rig. The coil, heated by town gas, has a thermal rating of 10000 kcal/hour. In the tests, cotton seed and castor oil were heated in the kettle to a temperature of 2600C by liquid ditolylmethane at a maximum temperature of 3200C. Design details of the plant used are given. The tests on this equipment lasted 18 months with many starts and stops. The number of hours during which the ditolylmethane reached temperatures up to 3200C was 700 hours. The most important property of high temperature organic heat transfer media is the thermal stability. During the 18 months operation the viscosity of the ditolylmethane rose by 5 -10% which should correspond to a resin content of 3 -6%. According to existing rules, a heat transfer medium need be changed only when the resin content is greater than 10%. To check this point the resin content of the ditolylmethane was specially determined and it was found to have Card 2/4 23424 S/094/61/ooo/008/002/003 Liquid ditolylmethane ... E194/E484 risen to just less than 5%'whilst the coke number rose from o to o.67%. Thus the thermal stability of ditolylmethane at temperatures up to 3200C was completely satisfactory. The heat transfer rate was adequate with a flow speed of 0.48 m/sec in the coils. The heat transfer coefficient results are in good agreement with data calculated by the usual procedure using the tabulated data given. Ditoly1methane is better than the usual diphenyl mixture in flash point and similar properties. It is accordingly recommended that liquid ditolylmethane should be used for heating and cooling of-high temperature industrial heat exchange equipment. There are 3 figures and 2 tables. Table 2.

Thermophysical characteristics of raw rubber mixes and their rela- tion to temperature PERIODICAL: Kauchuk i rezina, no. 5, 1962, 26 - 29 TEXT: The thermal and temperature-conductivity, as well as the thermal capacity of raw rubber mixes were determined experimentally at various tempera- tures. Four raw tire mixes, based on CM -30 APM (SKS-30ARM) and NR were used as investigating materials in addition to one vulcanized mix (casing), based on SKS-30ARM for reference. The method used to investigate ebonite mixes was used.J A new calorimeter (Fig. 1) was developed for determining the thermal capacity.- Ethyl glycol served as the calorimetric fluid. A comparison of the thermal co- efficients of tire mixes based on SKS-30ARM and ITR showed that these, as a rule, are higher than those for mixes based on SKS-30ABI~. The authors con6lude that the thermal conductivity of the raw tire mix, with a temperature range of 30 1000C, changes very slightly. This leads to the possibility of calculating the Card 1/3 3/138/62/000/005/007/010 Thermophysical characteristics of raw rubber ....

The thermal stability of both oils was tasted by residual-gas pressure in a flask with heated oil. at temperatures under 3ZOC, the stability of AMTL -300 oil was found to be somewhat higher than that of M600. Further experiments involved circulating the oil through a closed tubing circuit for 750 hrs ~Card 1/2 L 15701-65 ACCESSION NR: AP4047529 at 300, 315, and 330C. It was found that during the first 100 hrs, the heat- tranafer factors considerably decreased due to formation of a carbon-film depoz!,# on the inside of the tubing. The coking value, resin content, and viscosity were measured at various stages of the experiment: the deposit thickness was 0.04 and': 0. 05 mrn for AMT- 300 and M600 oils, respectively.

Flow in a circular cylindrical pipe is considered in order to determine the viscosity coefficient of the mean flow. First, the velocity distribution is determined by consideration of the equilibrium of an elementary volume of fluid. The analysis is carried out for two simple laws relating the viscosity to the mean velocity. The results are compared with experimental data. For the fix-st law good agreement is achieved at large Reynolds numbers but for the second law agreement throughout the turbulent domain is achieved; there is divergence in the laminar domain. The second law can be used to solve the problems of turbulent flow between plane Card 1/2 parallel walls and between co-axial cylinders. There
