83208 On Methods of Solving Geodetic Tasks Over S/154/60/000/004/602/004 Great Distances B012 B054 thatq with respect to accuracy, the series according to Bessel's method converge more quickly,and that this method offers certain advantages over the two others.. On the other hand, the coefficients have to be converted in this method...At present,.the author.is working at a special guide describing the methods of solving geodetic tasks (accurate and approximation methods) over great distances. In the second part of the present paper, the author gives some-supplements to-the suggestions made in the paper (Ref..4) for improving the Tables and formulas of Professor A. M. Virovets (Ref. 2). They are to be taken into account in a new edition. There are 4 figures and 5 Soviet references.

V., Professor TITLE: Present problems of spheroidal geodesy PERIODICAL: Izvestiya vysshikh uchebnykh zavedeniy. Geodeziya i aerofotos"yemka, no. 6, 1960, 3-6 TEXT: The author refers to modern means available for the surveying of distances (Shorans Hiran, etc.), on the one hand, and on the demands made on rocket engineering of measuring distances and azimuths between two distant points, on the other. It is stated in this connection that in consideration of the new situation, spheroidal geodesy has to start from the problem of large distances. Therefore, the principles of spheroidal geodesy basing upon the solution of problems involving small distances must be revised. It is pointed out that the designation "spheroidal geodesy" has not a general validity. Outside the USSR, the term "mathematical geodesy" is often applied instead. In the author's opinion, the object of spheroidal geodesy is the geometry of the geoid and the representation of the important parts of its surface on a sphere Card 1/4 S/154/6o/ooo/oo6/ooi/006 Present problems of spheroidal ... B116 B201 and a plane by certain mathematical laws. In this connection, the expression "spheroidal geodesy" is said to be more appropriate than "mathematical geodesy." The problem is discussed at some length. It is quite possible that the plane rectangular coordinates have to be replaced by new areal coordinates, as was suggested by F. N. Krasovskiy 20 years ago ("in future, rectangular spheroidal coordinates will be the principal coordinates of practical geodesy"). When using such coordinates, the measured lengths and angles could be used without any reductions, the transition from them to the rectangular ones in the Gauss-KrUger projection being fairly simple, while the transition from the geodetic coordinates to them would require not more work than the passage to the plane rectangular coordinates. In the interpretation of data regarding further geodetic networks with large distances between the points, there arises the problem of the planes of projection. Using the aposphere (a notion defined by Hotin) could be possibly of some use in the planes of projection. Papers published in and outside the USSR on the problem of "large distances" in most cases do no more than pose the problem, while offering mere varieties of methods devised in the past century. Vector and tensor calculus are still little used in spheroidal geodesy, and a S/154/60/000/006/001/006 Present problems of spheroidal ... B116 B201 scientific study is required to assign these modes of calculation their proper place in spheroidal geodesy. The first attempt in this direction has been made by Professor N. A. Urmayev. The young scientific workers of the kafedra vysshey geodezii MIIGA i K (Department of Higher Geodesy at the MIIGA i K) are already working on the application of vector analysis in problems of spheroidal geodesy, and results in this field will be expected in the near future. The old question of the use of normal sections for the solution of problems of higher geodesy is presenting itself anew. A mathematical-geodetic investigation of the properties of elliptic arcs and their azimuths will be required in order to be able to use the normal sections for the solution of these problems with some success. No such investigations are, however, being carried on systematically in the USSR or abroad. In this connection, the suggestion made by M. S. Molodenskiy concerning the use of chords of the ellipsoid are of great importance. All furmulas and tables in spheroidal geodesy are out to size of logarithmic calculations. The nonlogarithmic mode of calculation is applied to an absolutely insufficient extent to the solution of geodetic problems. In this connection, reference is made to the special tables compiled by Academician V. K. Khristov, a Bulgarian Card 3/4 A Present problems of spheroidal ... S/154/60/000/006/001/006 B116/B201 geodesist, for the use of nonlogarithmic formulas when determining longitudinal, latitudinal, and azimuthal differences of geodetic points. The Bulgarian Academy of Sciences published these tables in 1957 under the designation "Tables for the transfer of geodetic coordinates onto the ellipsoid by F. N..Krasovskiy for all latitudes with the aid of an arithmometer". Explanations to these tables have been provided by V. K. Khristov in Bulgarian, Russian, German, and English. It is pointed out in this connection that the most important thing in nonlogarithmic modes of calculation is to obtain formulas suited for programing. In particular, a much too cumbersome mathematical symbolism is now used in spheroidal geodesy. -One of the main problems in spheroidal geodesy is said to be the elaboration of a more rational and convenient symbolism.

TITLEt Sorption of Radioactive Isotopes by Aluminum Hydroxide (Sorbtsiya radioaktivnykh izotopov gidrookislyu alyuminiya) PERIODICALs ABSTRACTt Card 1/5 Zhurnal Neorganicheskoy Khimii, 1958, Vol. 3, Nr 1, PP-235-239 (USSR) Micro concentrations of caesium-137, strontium-89-90, cerium- -144 and ruthenium-106 were used as such isotopes. The ob- ject of the present investigation is the confirmation of the previous theoretical considerations (reference 1) according to the following mechanisms: 1) Ion exchange of adsorbed isotopes with potential-forming ions, or 2) Chemosorption (- chemical adsorption). In the case (1) the process can take place with charges of the same sign of the hydroxide-electro- lyt6 and with the ions to be adsorbed, - in the case (2) with different charges. It may be assumed that the adsorption of the afore-said isotopes by aluminum oxide will be analo- gous to that by iron oxide with respect to its character. The 76-1-43/43 Borptiou of Radioactive Isotopes by Aluminum Hydroxide isotopes were used as chlorides and without carrier. The depo- sit of hydroxide from aluminum chloride was obtained by 3 methods in view of investigating the influence of the ageing of the adsorbent on the value of adsorption of the radioactive micro-component. A) Aluminum-brine was produced by means of acetic acid in the radioactive solution, according to Gofman, and was (reference 3), subsequently coagulated, dried and centrifuged. The activity was determined in the stale eolu- tion. B) Isotopes were introduced into a ready hydroxide-soll further see (A). C) The radioactive micro-components were introduced into the solution 1 hour after the coagulationt for the rest, see (A). Sodium aulphate was used for coagula- tion. The pH-value was adjusted by means of caustic alkali (0,05 n). The concentration of the radioactive micro-.~compo- nents exceeded in no case 5 p Curie/t . The adsorption is expressed in 0 of the initial activity in the tables and figures. The values of adsorption in pulses/minute/0'i mg of the aluminum hydroxide are given in figure 6-6. The re- sults in table I show that the addition of Na SO .10 H 0 2 tie val2 up to 24,0 mg/loo mi exercises no influence on ue Card 2/5 of adsorption under the given conditions. Only the complete- Sorption of Radioactive Isotopes by Aluminum Hydroxide 78-1-43/43 ness of the aluminum-precipitation is influeno6d by the change of concentration of the precipitating agent (in ac- cordance with reference 4, 5). The dependences of the values of adsorption of the radioactive micro-components on the pH of the milieu are given in figures 1 to 5. With pH 5,5 to 6to the adsorption of ruthenium and cerium increases sudden- lyt in order to attain its culminating point with pH 6,5 to 7,0. The same holds for strontium, however, with a culminat- ing point at approximately 9,0 between pH 60 to 7,0. Thq. maximum adsorption for ruthenium and strontium amounts to 99,0 to 99,8 % of the initial activity, the same with stron- tium of 70,0 % (test C) up to 100 % (test A). Caesium is notadsorbed under all test conditions. pH 6,9 corresponds to the isoelectric point of the aluminum-hydroxide-brino (reference 6). Consequently, ruthenium and cerium are adsorb- ed with a positive charge of the hydroxide , strontium, how- ever, with a negative one. Taking account of the previous theoretical considerations (reference 1), it may be concluded Card 3/5 that the ruthenium- and cerium ions are adsorbed simultaneous- gorPtion of Radioactive Isotopes by Aluminum Hydroxide 78-1-43/43 1y with the aluminum ions, in their property as potential- -forming elements. The adsorption of the positively charged strontium on a negatively charged deposit takes place due - to the formation of aluminate. It may be concluded from figure 6 to 8 that the adsorption takes place here within the range of the rectilinear part of the isothermal line. It is shown in table 2 that the adsorption of cerium and ruthenium in- creases with the temperature, whereas that of strontium-89 remins practically constant. Fi-gures 1 to 3 prove that the adsorption of strontium decreases in the series of test con- ditions A - B - C. This is of importance for the purifica- tion of the radioactive waste waters from the laboratory by means of metallic hydroxides. There are 8 figures, 2 tables, and 6 references, all of which are Slavic. ASSOCIATIONs Ural Polytechnical Institute imeni S. M. Kirov, Sverdlovsk (Uraltskiy politekhnicheskiy institut im. S. M.

The dolomite used for filtering had been baked at 720-7500. The micro amounts of strontium adsorbed were de- termined using the radiometric method. The solution of radio- active Sr 89 was filtered through the fi'ter of magnesium mass. The relationship between the adsorptJon and the size of the filter layer and time of contact was investigated. The results showed that with a constant filtration velocity an increase Card 1/2 in the filter layer can increase the adsorption of strontium SOV/78-3-12-32/36 The Interaction Betweer.Semi-'1a1-:kied Dolomite and Strontium Ions in Aqueous Solution UP to-56%. The adsorption of the strontium depends upon the grain size of the dolomite mass, so that with coarse dolomite crystals the adsorption is 22%, whereas it is 44% with fine crystals. In filtering strongly alkaline strontium solutions (in NH4OH and in NaOH) it was found that the in NH 4OH solution required a relatively longer time for constant adsorption, where- as the adsorption from the NaOH strontium solution was zero. The adsorption of strontium on the dolomite mass is chemi- sorptive in nature. The adsorption is greater in the presence of anions which form salts of low solubility with strontium. There are 6 tables and 3 Soviet references. ASSOCIATION: Ural'skiy politekhnicheskiy institut im. S. M. Kirova (Ural Polytechnical Institute imeni S. M.

TITLE: Recovery of Mixed Ferrocyanides of Heavy Metals from Hydrosols and Suspensions PERIODICAL: Zhurnal prikladnoy khjmii, 1960, Vol 33, Nr 1) PP 59-61 (USSR) ABSTRACT: This is the first communication from a series of articles on the use of gelatinous foam for concentration of radio- active cesium solutions. In this work the adthors studied separation of colloidal and recipitated ferrocyanides (K2Mn Fe(CN )6 1 K4Col, Fe (CN56 61 N N14 Fe(CN)6 3, K2Zn3 Fe (CN)6 21 and K2Cu, Fe(")6 .) and Pb2 Fe(CN )6 from their solutions by means of gelatin foam. Solu- tions of potassium ferroeyanide and of the respective metal salts were added to 200 ml of distilled water. After addition of 1% of freshly prepared gelatin solu- Card 1/4 tion, the volume of the suspension was brought up to 300 ml, Recovery of Mixed Ferrooyanides of Heavy 77501 Metals from Hydrosols and Suspensions SO'V/80-33-1-10/49 and the solution was mixed and poured into the foam apparatus shown in Fig. 1. Recovbry of the solid phase (colloidal particles and precipitate) was complete after 3-4 min of foaming (sinee the ferrocyanides are colored, their separation from the solution could be easily seen). Relation between solid phase coneentra- tion and minimum quantity of gelatin necessary for the complete recovery of the former is illUstrated in Fig. 2. The necestary volume of gelatin solution also depends upon the pH value of the ferrocyanide solution. A neutral or weakly acidic medium was found to be most favorable in the tec6vpry process. For complete recovery of 50 mg of X4N14 Fe (CN)6'3' the volume of the 1% gelatin solution could be deereahed 6-fold (from 9.0 ml to 1,5 ml) b. changing pH of the. solution from 2 to 5.

The first study, which also describes the laboratory apparatus and the preparation of some reagents, is printed on P 59 of this issue (see also Abstract 77501).

The marked effect of the pH of the solution on the,extraction is shown in Figs. 1 to 6; full lines designate the foam extraction, dotted lines designate the centrifuging extraction; A is the Cs extraction (iii %); and B is the pH value. It was also established that a low concentration of the ad- sorbent (60 mg/liter) already gave a maximum degree of radioactive cesium extraction. The amount of the solution carried off as foam was approximately 1 to 1.4% of the initial solution volume, Practically 100% extraction was obtained from a solution with pH = 7 in a three-stage procedure. The first extraction yielded 98.84% cesium;* the remaining solution was treated with ferrocyanide and gelatin in the same amounts as previously, and the second f:oothing extracted 89-07% of the remaining cesium. Finally, a third frothing gave 81.98% of the cesium remaining after the Card 2/7 second operation, and the total extraction amounted to Extraction of Radioactive Cesium by 77506 Mixed Ferrocyanides of Heavy Metals SOV/80-33-1-15/49 1 1 7 8 S Fig. 1.

TITLE: Sorption of microquantities of strontium and cesium by vermiculite PERIODICAL: Radiokhimiya, v-5, ho-1, 1963, 32-37 TEXT: The sorption of Sr9o,and Cs134 by vermiculite from alkali and alkali-earth metal chloride solutions was studied. The sorption by cation exchanger KY-2 (KU-2) was investigated for comparison. The sorption on vermiculite did not depend on the Pn of the solutions in the range of 3 to 11. The results of the experiments are satisfactorily expressed by S.Yu.Yelovich and L.G.Kuzlminals equation (Kolloidn. zhurn., v.18, no-3, 1956, 268) made more accurate by the authors (Radiokhimiya, v.2, no.6, 196o, 734). The results for the sorption in the'presence of ions belonging to.group I and II confirm its ion-exchange character' the sorption being governed by the law of mass action. Ce was i sorbed by vermiculite exceptionally strongly, which is explained by~; the high polarizability.of Ce ion and the volume of hydrated Ce .on being similar to that of hexagonal voids in the vermiculite 3.

The durability of metallocord is 5 times higher than that of viscose-, and 3 times higher than that of caprone cord. Tires can be produced 2- to 4-PlY instead of 8- to 14-ply as is usual for textile tires. Metallooord tires can stand a higher load. Because of the lower thickness of tread, and good heat conductivity of the metallocord, it is possible to use thicker protectors. As the metallocord does not stretcht the wear of tire6:: and - treads becomes smaller. Steel is used as basic material for the production of metallocord. Differently thick ropes are twisted from steel wire 0.15 mm thick. These ropes are wound over a rubber layer onto a special drum, and covered and rolled with another rubber layer of the same thickness. The pressed metallocord is then used for the tire production. There Card 1/2 are two types of tires possible: standard tires with the cord 66909 Metallocord SOV/29-59-11-28/31 threads intersecting at an angle of about 900, and tires whets the cord runs meridionally.- The Omsk Tire Factory was estab- lished in the first years of the Rational War, The faotory em. ploys seveTal thousands of workers. Production was quadrupled in the first 10 postwar years. In the meantime, the old machinery was completed'and replaced. This allowed a further production increase of 30% in the past 3 years. A number of talented inventors and efficiency experts grew up in the fac- tory# including A, Gavrilov, A. Kolltsov, V, Guzeyev, I. Kli- mov; B. Markov and K. Mishin, mechanics; T. Terekhova and G. Limovetskiy engineers; V. Sapronov, It. Gil'shte ~ V. Filip- povp technical engineers, and others. About 4,000 inventions and efficiency suggestions have been realized in recent years. This resulted in savings of 25 million rubles for the factory. The factory will soon start production of metallocord tires. There are 3 figures and I table.

TITLEZ TirJlWith Meridional Arrangement o f Cord Strands in Carcass PERIODICAL: Kauchuk i Rezina, 1960, No. 1, pp. 6 - 10 TE(T- The article describes design and characteristic features of tire with meridional arrangement of cord strands, as invented by Michelin and first produced in 1947 under the designation "type V. Under a licence issued by Michelin the same tire is produced in various European countries and in the USA by Goodyear and Firestone. After enumerating the advantages of this new construction over the con- vent'donal design, the author gives a brief survey of the development work pursued irl the USSR by the NIIShP, which in the first place aims at setting up a new techno- logy of production providing for two distinct phases, Viz. assembling and expanding of the carcass and secondly application of breaker and tread on the formed carcass. Tires of the new type produced for experimental purposes are being tested in regard to savIceableness, roadability, resistance, lateral strength, efficiency etc. Preliminary results of laboratory tests are given in Table 3 showing that these tires have a lower temperature, greater radial deformation, and less specific Card 1/2 S/138/60/000/01/02/010 Tires With Meridional Arrangement of Cord Strands In Carcass pre&sur-e on the surface of contact, which results in reduced wear of tread. Further development work is being conducted with a view to producing new special types of tires, making allowance for the characteristics of the new design. Another task in connection with production consists in developing new special rubber ensuring sufficient rigidity and cohesion of side walls. Special plant equipment needed for industrial production of the new tires needs also to be developed. Tentative caleulations regarding cost of material and production based on literature data V/ show that the production of tires with meridional arrangement of cord strands presents considerable interest from an economical point of view due to saving of material and an increase of the roadability of the tires.

Arsenazo II has a number of advantages over arsenazo I and many other reagents suggested for 'determining thorium; its chief advantage is that Th can be determined in sufficiently acid-solutions (0.1 - 0.6 N HC1), and in the presence of rare earths, sulfates, phosphates, etc. In acid solutions IV III arsenazo II reacts with Tht Zrt Ti, U , and Fe , in weakly acid and neutral solutions with Al, U ViI-Or, Cu, ZTRj etc. Fig. 1 shows the absorption curve of the reagent and its Th compound. The selectivity of Card 1/4 Photometric Determination of Microquantities S/075/60/015/004/014/030/XX of Thorium in Rocks by Means of Arsenazo II - B020/BO64 determining Th with arsenazo II is also warranted by the proper choice of the acid concentration and the use of masking substances. In 0.2 N HC1, the effect of almost all other elements is reduced to a minimum, and the masking of thorium by phosphates and sulfates is still slight. Large amounts of Zr and Ti have a disturbing effect, small amounts can be masked by adding of phosphates. 2r Tit 3r Zr, 4-8r Nb, and Tat 5r Fe III , 5r Criii 5r Mo, V, and W, 40j-u Vi , 0.5 - 1 mg Al, and 10 - 150 mg K, Nat Cat Mgt Z:TR, and Fe Ii do not affect the determination of 10,rTh. The limit is 5 - 10alTh. The analyzed substance is decomposed by two- or threefold evaporation with hydrofluoric acid, the majority of Zr, Tit Kb' Ta, Alt is, TJ Vi are-separated by the formation of soluble fluoride complexes,7and thorium is precipitated together with the rare earths and ca-1-cl-u-m-which are its carrier substances. Variants of the separation method are given. In the fluoride method, precipitation is repeated by the action of hydro- fluorio acid upon the hydroxide precipitate obtained after the dissolution of the first fluoride precipitate in hydrochloric acid and prdbipitation in ammonia. In the fluoride-oxalate method, after the decomposition of the Card 2/4 Photometric Determination of Microquantities 8/075/60/015/004/014/030/Xx of Thorium, in Rocks by Means of Arsenazo II B020/BO64 sample with fluorides and removal of the fluoride ion by evaporation with HC1+HG10 41 homogeneous coprecipitation of thorium, with the oxalates of rare earths or calcium with acetone dioxalic acid was carried out at the acid concentration suggested by V. I. Kuznetsov and I. V. Nikol'skaya (Ref- 7), and F. V. Zaykovskiy and L. I. Gerkhardt (Ref.,B) for calcium. The oxalates were filtored off, annealed, the oxides dissolved in HC1(1:10), and thorium photometrically determined with arsenazo II. The analysis took one day. The chromatographic separation of the impurities by ion exchange on the Soviet resin KY-2 (KU-2) in the H-form (100 mesh) is described. Table 1 shows the ratio between thorium and some impurities before and after separation, thus proving that all separation methods examined give satisfactory results. The degree of thorium extraction was determined by means of its radioisotope UXI and by measuring the soft A-radiation UXII with which it is in equilibrium. The total thorium, losses amount to a maximum of 12-14%. Table 2 shows the results of thorium, determinations by the three methods mentioned. They indicate that two methods, i,e,, double fluoride precipitation (time of analysis, 6-8 hours) and fluoride-oxalate precipitation (time of analysis, 24 hours) can be recommended.

For example., lead and iron (III) 8-hydroxyquinolinates are separated from thallium (1) 8-hydroxyquinolinate by extraction with benzene at pH 9, and thallium 6-hydroxyquinolinate is then extracted at the same pH with isobutyl alcohol. Yttrium and strontium 8-hydroxyquinolinates and thenoyltri- fluoroacetonates, and indium, and thallium (I) 8-hydroxyquinolinates are sepa- rated in a similar manner. There are 5 tables..

It was found.that tZ for soft steel [63 0*2 kg/em2J% ~ and the maximum foroa drops below the Her I I theory values above this 6 a The diameter of, the de:l.'ormedarea was found to be greater than that for the elastio'case and also greater than for static loading (see Fig. I on the Enclosure). These results were also observed with other mate- rials Repeated #pacts With the same specimen showed that after:100 blows at 2 3.93 x 10 kg/cm the maxlm= inpact force increased, the impact duration do- creased, and the coefficient of recovery increased (46.8 - 61.1 kg,-.206 176 jAsec; 0.667-0,826), Additional experiments showed that this effect is due to work hardening in some cases~and due to density increase in the Impact areas in others (for softer materials), Experiments with glass showed that the Hertz rola tion is satisfied for brittle materials beyond 16 (when first cracks occur) and holds -until complete failure of the glass.(pulverization of impact area).
