An elz.sto-viscosimeter with os- cillographic recording and an elasto-relaxoMeter were used to measure these properties. In Figure 1, the values for a 6% rubber solution in decalin are iresented. The ultimate deformation under shearing conditions attains a value of 5,00(r/'I. Figure 2 shows that vulcanization of a 2% rubber solution augments the elastic deformation to 4,000 - 5,004.

Moreover, the ultimate shear deformation breaking (up to lo'0OCFQ was determined. The obtained curves art? similar in form to those of -solid .-Mber.

It was found that the maximum values of elastic deformation represent 770 and 1.10011~1 respectively. On the whole the found properties give evidence of a structure and its demolition in rubber solutions.

Specimens were heat treated to obtain a close approximation to equil-ibrium for the carbide/solid-solution phases, For each alloying element increasing concentration was accompanied by decreasing internal-friction peak maximum. Increase in alloying-element concentration beyond a critical value had'little- effect on the decroment-versus-temperature,plot.

The experimental conaitions did not permit a direct quantitative study of the effect of the alloying.elen,ents on dissolved-carbon concentration in ferrite. This information was obtained indirectly by malting certain assumptions and showed that the elements can be arranged in the ft,llowing order in decreasing effect for a given element/carbon atomic ratio on the dissolved-carbon concentration: niobiurtit varLAdium, tungsten, triolybdonum, chromium, manganese. The given values of the offect for different 'values of the ratio has practical importance for deciding the effect of alloying on ageing, for instance. There are 2 figures and I table.

Also the angular distribution of the fragments accompanied by fast protons was investigated. The emission of a pion could never be established. From the results obtained and from a comparison with the theory the oonclusion ray be drawn that at such low pion energies the fragment production is preceded by a n+ + d -> p + p-rqa~tion, i.e., the pion is absorbed by a quasideuteron in the nucleus, and only fast proton produced thereby is responsible fear the fragmentation.

A comprehensive and up-to-date work of this sort is stated to be an urgent need, in view of directives of the Twentieth Congress of the USSR Communist Party to expand the production of pig iron, titeel, and iron ore during the period 1956-60, and in view of the current shortage of available iron ore. COVERAGE: In issuing this volume, the Interdepartmental Permanent Committee on Iron, AS USSR, has endeavoredtto give a scientific analysis of the iron-ore reservod available.- to the USSR iron-and-steel industry, to describe the beat means of utilizing individual ore deposits, partic- .ularly during the Sixth Five-Year Plan period (1956-6o), and to indicate the nature of the re;3earch work required for an economic evaluation of thooe deposits which have Card 2/21 not'as yet been sufficiently studied,. Iron Ore Reserves of Ferrous Metallurgy In the USSR (Cont.) 243 pig iron, of which 35,000,000 t are obtainable from currently exploited deposits. More than 51% of the industrially signi- ficant ores are located in the eastern regions of the USSR; only 12% of them require no concentration. The expansion of the USSR iron-ore industry ean be achieved 'Ln the main only through mining lean ores, [new) deposits of rich ores being located principally In remote, thinly populated regions. Of the 208,500,000 t.of prepared ore scheduled for production in 1970, 109,400,000 t.muat be obtained from new deposits or from new sections of old deposits, the major portion of which con- sists of lean ores. Some 60 deposits are scheduled for active exploitation by 1970- (Estimation of total Iron-ore reserves is as of 1 January 1956, whereas ore-quality evaluations, statements on hydrogeological and mining conditions, and de- scriptions of deposits and their vicinities tire based on infor- mation available as of 1 January 1955). Old and new deposits scheduled for development are named and described (for names, Bee Table of Contents).

The main role in Vis re-education program is played by the schools of the GVF. The Hiyev Institute of the Aeroflot has increased its effort to prepare engineers and pilots for jet planes. The School of Advanced Pilotage (Shkola vysshey laknoy podgotovki) and training squadrons (uchebnyye eskadrilli) have trained pilots to fly the Il-14 and Il-12. By 1960, the number of students registered for various correspondence courses should triple, as compared with 1953. In 1957, the first group of graduates from correspondence courses, both technicians ani engineers, will graduiLte at the Kiyev Institute of GVF. The engineering diplomas were be- stowed upon: I. V. Orlovets, aircraft commander of a Tu-101+; G. F. Zhukovskiy, chief of the LERM at the Kuybyshev airport; P. D.

In 4.958, the squad saved 26,900 rubles of direct expenses. The field work lasting until December reduced considerably- the savings of the squad. In the central part of the Europear.area of the USSR, field work should be finished by November. The squads must be equipped with cross-country motor trucks. Wood transport should be ca=ied out from December until March as a rule. Geodetic squads should have indoor-service groups under the direction of a brigadier. Buildial squads should have no more than 5-6 men. These conclusions co-Ad be made on account of the working experience by this squad. Card 2/2 ASSZONYI,, Csaba 6-1-., -Z, 11 ..

Some of these funtitions could, in certain limits, be also used for calculatlons in cases where the outflow passos under the gate, o~i the top of the dam. The author d.e-- scribes research she did on the model of such a dam.ln these tests, the zone of surface regime was determined for in- variable outflow (different gate-openings) as well as for invariable level of upper water with different gate openings.

A. Baykov, TsNI1ChY4 developed a nov classification, consisting of three groups. Investigation tests (group 1), include *direct and indirect methods of determining optirmim chemical composition, final mechanical properties, and the properties of the veld-adaucent zone c.nd the base metal. Acceptance tests (group 2) are made to verify the chemical composition of the steel and*to com-. pare varying toughness of the weld-ad,acent zone at room and negative tempera- tures; technological -tests (group 3) are carried out to determine the suita- bility of metals for the intended structures; these tests are to be performed at the Ir~stitutes. One of the main factors of determining the weldability of steel is the reaction i'.)f the base metaL to the thermal: welding process. The Card 1/2 I f On the weldability of steel S/135/6.3/000/002/002/015 A0061AI01 Institute of 'Metallurgy imeni A. A. Baykov developed the JIMIL-1 method to deter.- mine indirectly the effect,of the thermal process upon the base metal, In but-v-- welding sheets, the spots of the ;~.eld-adjacent zone are heated to different tem.- peratures under the effect of the thermal welding cycles; these spots are lo- cated in the overheating, normalizaticn, partical crystallization and disinte- gration zones. Corresponding to structural transformations in the heat-affected zone, the mechanical properties are also changed. The use of RET-1 rod speci- mens for determining final properties in the heat-affected and disintegration zones maker it possible to characterize more completely the reaction of the baso. metal to the thermal welding cycle. Voreover, the small amount of metal re- quired for the tests, makes it possible to evaluate this reaction as a function of individual components in the steel, varying the chemical composition of ex- perimental heats. In 'this way it is rossible to'establish optimum contents of alloying elements and to recoizimend well i,,,eldablc steel o' optimum composi'.ion for large-scale trials.

T17LE: The Volt-Second Characteristics of Solid Homogeneous Dieleotries PERIODICAL: Izv. Tomskovo pilitekhn. in-ta, 1958, Vol !A, pp 16 - 19 ABSTRACT: The authors measured the volt-second characteristics at sparkover in the homogeneous and inhomogeneous (one electrode being in the form of a point) field of it great number of solid dielectrias: single crystals of NaCl, KC1, KBr and KJ, single crystals of Seignette's salt, ice, foliated tale containing water of arystallization, porcelain and others. For the sparking voltage a value was selected at which sparkover occurred with a probability of 90%. In the case of all the dielectricz; investigated, when samples having a thickness of 0.15 imn were exposed for 1 - 10-7 see or less, an in- a.-ease in electric resistan,2e was observed. The rise in sparking voltage under short exposures is caused by discharge delay. It is well-known (cf. RZhFit9 1959, Nr 1, 11710 that, in the case of exposures shorter than (2 - 3) - . 10- see, the time delay is actually the time of fanning the discharge Card 1/2 tf * tf was ascertained fron the voltage oscillogram.

The first stage of the investi- gation comprised acid (HNO 3 or HC1) leaching tests in 'which the effect of the following factors on the recovery of rare-ear-th elements was studied. acid concentration; leaching temperature;' solid/liquid ratio and leaching time. ' Two i-iiethods of leaghing were tested: agitating the pulp for one ho~ar at 80 - 90 C and filtering the product; vacuum percolation for one hour at 70 - 80 OC.

Based on these results, a method of extracting rare-earth motals from various starting materials wrts developed; the flow sheet of the process is given Ln the paper. Finally, the possibility of using tributyl phosphate to extract; rare-earth metals directly froff, the pulp was studied. A crude, fluorite rare-earth metal concentrate, mixed with 50% IINO 3 solution (liquid/solid ratio 1:1), was stirred for 15 min after. %-7hich tributyl phosphate (organic phase/irat8r ratio = 2:2.) was added to the pulp. The_pulp, 0heated to 80 C, was agitated 'for one hour, cooled to 25 200 C, agitat~d.again for 10 min and then left to settle. Tributyl phosphate was then decanted anti th'.e second stage of ctxtraction was carriod.out with a fresh quantity of tributyl phosphate. After two operations 790% recovery ot, rn203 was attained. This value could be increased to 89*40% by adding to the pulp 1?,, of Al 0 in the form of aluminium rLitrate. 2 3 ,The. difficulties in attaining a.higher recoviary by this method were ap,L~arently associated with losses of tributyl phosphate and this problem requires further study.
