It is assumed that, among natural damped oscillations of such a system, there are some known oscillations that have a very high Q. The problem of oscillations of an open resonator forced by external currents and the Cauchy problem are solved by an expansion into continuous -spectrum eigen-functions.1 The solutions explicitly show the resonance part of the field which is clue to high-Q L.Sa,d 1/Z L 13352-66 --,3Q ACC NR: AT5027159 natural oscillations; simple formulas are developed which describe this resonance part. Application of the general formulas is illustrated by an example of a homogeneous isotropic sphere excited by a radial electric dipole and acting as an open resonator. It is claimed that the formula for Q-factor developed by C. G. B Garret et al. (Phys. Rev. , 124, no. 6. 1807) is incorrect. "The author wishes to thank P. L. Kapitsa and V. A.

Vaynshteyn, Elektricheskiye Stantsil, No. 5, May 1957, Pages 47 -- 49. When a power system operates with some of the generators provtded with automatic excitation regulators and the other part of the station is operating without regulation, the stability margin of the system cannot be calculated by con- si.dering the regulated and unregulated generators separately. It is necessary to analyze the operation of the system as a whole and the author proposes a scheme to simplify these calculations and to determine to what extent the regulated generators provide stability for the unregulated ones. Re- sults obtaLned by means of such an analysis make it possible, in some cases, to avoid shutting down part of the station when some of its regulators are out of order, even when work- ing at large power angles.

The author considers schemes consisting of the logical elements A , V and 0;-the schemes yield the carry-over E in the next place as well as the sum B mod 2 of the magnitudes b, c and e. The operation 9 has to be applied only once. It is assumed that the schemes do not contain cycles. The author investigates the question how largeg under these assumptions, is the 4nimal number of the diodes need6d in the scheme of the adder, and how do the most economical schemes look. At first he investigates optimal schemes consisting only of the elements V and A . Then it is stated that B cannot be obtained from b, c, e only by A and V; an inverter must still be used, where E has to appear at its entrance. The scheme for obtaining E used in the apparat= NAREC has 8 diodes and is the single optimal one (up to permutations of the b, c, a and an exchange of V and A ). For a restriction to 16 diodes, the function B can be obtained with two Card 1/3 86816 3/020/60/135/ .'005/001/043 C111/C222 Schemes for an Adder of Numbers Having the Same Place - Value essentially different schemes.

For five magnitudes (b, b1f C9 of, e or b, b', of c1, et) there exists only one optimal (up to an exchange of b and c and up to dual carry-over) scheme with 16 diodes (fig-4c,d).

The author presents examples of several substantial technical improvements in making certain parts at the Gor'kiy Ant~mobile Plant im. Molotov. Leading individuals and groups of technicians and qualified workers, the so-called "complex brigades", developed and introduced more efficient methods of production to achieve better utilization of sheet metal. Marked improvement in the quality of the finished product coupled with lowered costs of production are tangible results of the changes introduced by these men in making certain parts by cold stamping.

The documents which are of the greatest interest to Russian historians and which have also been made accessible to them, are manuscripts kept in the Stockholm archives in the depart- ment known as "Moscovitica". A similar department of the Swedish State Museum (Rikoarkivet) has partly,been examined by Russian and S-jedish historians, but those manuscripts, which are of the greatest importance for Russian history and ihich are known as "Extraneall, have hitherto remained untouched as also several documents and collections which are in private hands. One of them (Erikabergo arkiv),,is now boing sorted, Card 1/3 but it is not accessible to the public. Nobody has ever PA - 2470 Valuable Documents Concerning the History of the U.S.S.R. in Swedish Archives. systematically investigated the hand-written books and docu- ments which are of "enormous value for the history of the- U.S.S.R." and which~ are kept in the archives of the Swedish Ministry of Commerce and Industry, the War Ministry, and in the manuscript libraries of Upsala, Lundt V4steros, in the Royal Swedish Library, and elsewhere. The author is of the opinion that it would be of eiminent im- portance for Soviet history to gain access tothe manuscripts kept in Swedish archives and other institutes. The author himself was able to travel to Sweden in the summer of 1956 and to interest himself in such documents kept in Swedish archives as deal with the history of Russia. Within four pages the author published his comments, extracts, and notes on what he was able to see (with 2 illustrations), and from this it appears that indeed there is an abundaice of material bearing on Russian history in Swedish archives. He mentions a number of facts which have hitherto either been unknown or are in Card 2/3 complete contradiction to what has hitherto been accepted.

Chelyabinsk, Knigoizdat, 1957, pp 95-105 ABSTRACT: Radioactive Fe59 (introduced in the form of Fe oxide) was employed in conjunction with the method of overturning of molds in order to investigate crystallization processes in ingots of steel ShKhl5SG (2.65 t) and of steels 10 and 45 (6.2-t ingots). The radioactivity of various zones of the ingot was determined from the radiation intensity of 3.5-g specimens of metal drilled out on different levels of a longitudinal templet of the ingot. As the crystallization progresses, the two-phase region on the sides of the ingot amounts to 30-50 mm, After the formation of a zone of columnar crystal5, a two-pha-e region fed with Card 1/2 liquid metal from the central part is formed in the lower part SOV/ 137-58-8- 16552 The Rate and Sequence of Crystallization in Ingots of Killed Steel of the ingot. In a 6.2-ton ingot, the height of this zone extends to 850 mm. Up to a certain time (approximately 80 min in the case of the 6.2-t ingot) the thickness of the crystallized layer (including the two-phase region) taken in a horizontal section of the ingot is proportional to the sqtiare root of tllv crystallizatiun time. Deviations from this relationship, which occur toward the end of the crystallization period, are attributable to a more rapid form- ation of a two-phase region at the center of the ingot. Extension risers, employed in production of high-quality steel ingots, may be removed only after the crystallization of the ingot has been completed. Bibliography. 19 references. Ya.L. 1.

The radioactive isotope Fe59 was introduced into the slag as oxide at the start of the period when boiling alone was in progress. Samples of metal and slag taken thereafter were checked for radioactivity. Isotope exchange was found to exist between particles in different Fe phases, exhibiting a considerably greater velocity than the process of FeO trans- port from slag to metal. This circumstance permits the conclusion that the limiting factor in the process of oxidation in an open hearth bath during the period of pure boil is the rate of transport of wustite across the slag-metal interface, Card 1/1 A.

Nauchno-tekhn. o-va chernoy metallurgii, 1957, Vol 18, pp 442-449 ABSTRACT: Results are presented of a comparative investigation of the technical and economic indices and the quality of low-carbon killed grades 10 and 20 steels smelted with preoxidation (P) and without P by blast-furnace Fe-Si in the furnace. The steels were smelted in 100 and 185-t furnaces at the Chelyabinsk Metallurgical Plant. On deoxidation in the furnace by Fe-Mn alone, the duration of a heat is diminished by approximately 31o, the cost of one ton of steel is Rubles 2.44 less than on deoxida- tion with blast-furnace Fe-Si. Burning loss of Mn in tapping heats without P is 15% greater, and total burning loss of Si diminishes by 20-25% on the average. Deoxidation of Fe-Mn in Card 1/2 the furnace results in a smaller cooling of the bath and makes 137-58-6-11691 The Smelting of Killed Carbon (cont.) it possible to heat the metal before deoxidation to less elevated temperatures than in P with blast furnace Fe-Si. This eases and speeds the heat. The tapping of heats without P makes for a diminution in L P] by 0.003-0.005"I'D in the finished steel and a diminution in 1-1 by 0. 5-0.7 cm3/ 100 g in the ladle sample. The quantity of nonmetallic inclusions electrolytically isolated from the finished steel and the A1203 content are somewhat higher in heats oxi- dized in the furnace by Fe-Mn alone. It is established that the mechanical properties of the finished metal, and rejects due to macroscopic faults in structure and surface defects are not dependent upon the mode of deoxida- tion of the metal in the furnace.

Moscow, Metallurgizdat, 1958, pp 203-217 ABSTRACT: Radioactive tracers were used to investigate the crystalliz- ation of 2.65-t ingots of ShKhl5SG and 6.2-t ingots of Nrs-10 and 45 steels, bottom poured, 3-5 batches of Fe59 (4.5-14.5 millicuries per t steel) were introduced as Fe203 mixed with Al powder. The tops of the ingots were held in the liquid state by periodic additions of lunkerite pipe eliminator. At the same time, crystallization of Nr-10 steel was also studied by over- turning three ingots on single stool at different time intervals after pouring. The isotope was introduced at the moments when Card 1/3 the residual liquid metal from each of these ingots was poured SOV/137-58-9-18676 Nucleonic Study of the Rate and Sequence of Steel-ingot Crystallization into a fourth on the same stool. The thiclness of the frozen layer as deter- mined by radiography was greater than when determined by pouring out the liquid residue of the metal. This is explained by the fa,7t that the zones of isotope distribution describe the region of the ingot occupied by liquid metal, whereas the thickness of the crystallized layer determined by pouring out de- fines the region of solid metal phase alone. The difference between them is the magnitude of the region in which two phases exist. The length of that region along the sides of the ingot in the coitrse of crystallization does not exceed 30-40 mm. At the conclusion of the formation of the zone of columnar crystals in the bottom of the 6.2-t ingot there arises a two-phase region at- taining 850 mm. in height- This region comes into being as the result of the accumulation of equiaxed crystals that have torn away after formation on the interface between the solid and liquid phases. The crystallization of the two- phase region is intermittent in nature. The development of V-segregation and axial porosity are dependent upon the taper of the ingot and the condi- tions under which the two-phase zone is fed liquid metal from the upper por- tion of the ingot. In the making of high-quality steel, the hot top should be removed only after the body of the ingot has completely hardened.

TITLE: The Quality of Steel from Pi6 Iron Produced with a Constant Moisture Blast (Kachestvo stali iz chuguna, vyplavlennogo na dutlye postoyannoy vlazhnosti) PERIODICAL: Stal', 1958, No.1, pp. 24 - 27 (USSR). ABSTRACT: The influence of moisture content of bl-st on the hydrogen content in pig iron and the influence of hydrogen content of pig iron on the hydrogen content of steel as well as flake sensitivity of steel on the hydrogen content in the liquid metal were investigated. Nos. 1 and 3 blast furnaces on the above works were trans4erred to operation with a constant moisture blast (15-20 g/m'). This resulted i the smoother operation, high8r blast temperatures ?50 - 800 110 (against previous 450 - 500 C), increase in output (No.1 - 3%; No-3 1.3%) and a decrease in the coke rate (No.1 - 6 .5%; No-3 1.3%). As the works produce quality steel it was considered necessary to check the possible effect of higher moisture in blast on the steel quality. It was found that with increasing moisture content in blast, the hydrogen content of pig iron increases but not Cardl/3 proportionally. However, the mean content of hydrogen in the 133-1-?/24 The Quality of Steel from Pig Iron Produced with a Constant Moisture Blast open-hearth bath after melting and on teeming was found to be practically independent of the hydro en content of pig or moisture content in the blast (Fig.151 The final hydrogen content of steel on teeming was not correlated to its content in the corresponding pig (Table 1, Fig.2).. The comparison of hydrogen content in pig, steel and rolled products of various levels of moisture content in blast is shown in Table 2; the comparison of the degree of flaking in semis and their hydrogen content and the mechanical properties of finished steel at various levels of moisture in blast - Tables 3 and 4, respec- tively. It is concluded that the hydrogen content of pig iron has no influence on the hydrogen content of quality steel after melting and on teeming. The direct relationship between the Blake sensitivity and hydrogen content of liquid metal was not established. The methods of heating and cooling flake- sensitive steels used on the works secure the absence of flakes in finished products at any level of moisture in the blast. The macro-structure of rolled semis is independent from the moisture content of the blast. There are 4 tables, 2 Gard2/3 figures and 6 Russian references.

When investigating these "tongues" on Card 1/6 S11331611000110011WVOI 6 A054/AO33 Crystallization and Quality Improvement of 18-3oxrT (18-30KhGT) Grade Steel etched longitudinal and lateral macrosections and on the longitudinal hardened fracture, it was found that they were actually laminations of the central zone of the ingot. Macrostructuraltests revealed at the place of laminations*an accumula- tion of non-metallic impurities, extending along the axis of lamination. More- over, investigations of the longitudinal hardened fracture showed that this lami- nation is an internal defeot of the metal connected with the crystallization of the ingot. Therefore, tests were made to determine the character of brystalliza- tion and the structure of 18-.30h%GT grade steel ingots. The crystallization proc- ess was studied in 6.2-ton ingots by the tilting method, radiometry and tempera- ture tests. In the radicmetric method (Ref. 1, M.I. Kolosov, A.N. Morozov, et al.: "Rate and Sequence of the Crystaillzation of Killed Steel.Ingotd'. In the collectioni ";The Application of Radioactive isotopes in Ferroug Metallurgy", Chelyabinsk, 1957), the Fe59 radioactive Isotope was applied. The metal tempera- ture during crystallization was recorded at distances 665, 1,125 and 1,425 mm from the riser, with platino-rhodium-platinum thermocouples, protected by double- wall quartz tubes between which graphite rings were fitted at each level. During crystallization a double-phase zone formed along the axis of the Ingot. The con- siderable toughness of the 18-3MGT steels makes the feeding of the central part Card 2/6 1/ooo/ool/oo2/o16 9/133/6, Ao,=4A033 Crystallization and Quality improvement of 18-30XFT (18-KhGT) Grade Steel of the ingot difficult, causing the origination of a porous zone. As the location of this central porous zone coincides with the lamination in the rolled product it can be assumed that lamination Is oaus,~d by the porosity of the metal. In the pla- ces of lamination consideraKe &mounts of non-metallic Impurities were found imped- ing the scalding of the lamination even at greater reductions. Based on the tests two methods were found to prevent laminatim 1) reducing the porosity of the cen- tral part of the Ingot and 2) reducing the quintity of non-metallic impurities. 1) In order to reduce the central porosity, the process of feeding the central area of the ingot had to be improveJ. Mf-&Eures were taken to increase the time during which-the metal is liquid in them hood of the riser. It was found, however, that neither the application of "lunkerit-e" with an aluminum content of 28% in- stead of 14%, added in quantities of 3 - 4 Rix/ton insttad of 1.5 2 kg/ton, nor the use of lunkerite containing 35 - 50 % magneaiwm powder (1-5 2.0 kg/ton) yielded a considerable improvem6nt of the ma-,r:)structure. Thus it was not possible to improve the feeding of ths Ingot with liquid metal by increasad heating of the top. Better results were obtiined in this respect when the riser hood was insulat- ed by asbestos sheets (10mm thick) bstbw-~en its casing and lining and by winding Card 3/6 3/133/61/000/001/002/016 AC-75-VA033 Crystallization and quality Improvement of 18-30X rT (18-,-5oxb-rT) Grade Steel asbestos cores, 22 mm thick, or asbW~-o3 sheets around the Ingot molds, at a dis- tance of 500 mm from the top, fixed with sheet iron. The riser hoods were also mounted on asbestos disks. The longitudinal templates taken from ingots malted in insulated Ingot molds showed a sati5fk.,~'ory dan5ity and the axial porosity found in conventional Ingots was absent. The produaf.:.% roLled from IngotB produced with the insulation method (140 x 140 mm section) were alzo free from lamination. 2) The second method to prevent lamination, i.~., the reduction of non-metallic Impu- rities was tested with 3 kindi of deoildizing agents'. a) Silicomanganese in the furnaae and 115% solution of ferro-siliciLua In the ladle (_-,onv6nt1ona11 mathod),, b) 15 - 17 Rg/ton AMS alloy in t.h,? furiiace and elolution of forrostliclum In the ladle; c).manganese silicate In the furnace and calolum-silloon In the ladle. The best results were obtained with method b) (3.05% rejects due to laminatloh and 0.06% rejects due to macrostr-acture, while the corresponding figures for meth- od a) are 5.05% and 0.5% and for methrd c) 17.0%) (see table). To improve the steel quality, further tests were carried out in 1958 - 1959 to study preliminary oxidation with silicochromium, instAad of AMS, the use of titanium-containing scrap instead of ferro-titanium for alloying aand the optimum metal temperature prior to deoxidation, ensuring a satisfactory macrostructure and metal surface. By employing titanium-containing scrap the temperature drop in the ladle decreased Card 4/6 a V-J-/ fiv33 A Crystallization and Quality Improvement of 18-30,X1-T(18-3OKhGT) Grade Steel and the toughness of steei was reduced.
