The strength of the rails should be increased to 100-1.20 kg/sq mm and their yield point to 80 kg/ sq mm and up, without deterioration of the plastic properties. This can be obtained either by alloying the rail steels or by a heat treatment consisting of volumetric hardening. Tests carried out at the Nizhne-Tagil Metallurgical Combine gave the following results: The proper- ties of rails made of low-alloy steels without heat treatment were improved only slightly while the production became much more expensive, When the rails were made of alloy steels with a higher chromium and nickel content, their properties improved but the technological difficulties involved also Card 1/8 S/135/61/000/002/006/014 Volumetric Hardening of Rails in an Industrial..

Tests were also carried out with chrome-vanadium steels (Cr: 2.5-3.2%; V; 0.1-0. ea), For the rails of this alloy - without heat treatment - the following values were obtained: &B C~s kg/sq mm kg/sq mm 115-130 70-95 7-10~5 20-55 Card 2/8 SI!331611000100210081014 Volumetric Hardening of Rails in an Industrial... A054/AO33 This steel costs 31 rubles more than the M75 type and the rails made of it are twice as expensive as the conventional. ones. However, tests carried out at the NVAK, in 1957-60, proved that rails with the required properties can be obtained from carbon-steel by volumetric hardening in oil with subsequent annealing. For this process a semi-industrial pilot installation has been designed, consisting of a 10-compartment, 50-ton furnace for rapid heating and a unit for oil-hardening. The furnace-compartments are arranged in one line, 1.600 mm apart. The spaces between the compartments are covered with drums under which water-cooled rolls for delivering the rails are mounted. Each compartment has eigh" two-conduit, short-flame Wrbulenne burners of VNIIMT -design for coke-gas burning, The most uniform heat distribution in the furnace can be oblained by a chess-board arrangement cf the burners on the upper and the lower levell of each compartment, the thermal load being distributed between the upper and the lower burners at a 88-12f. ratio. The furnace is provided with shelves and guiding mechanisms for feeding the rails to and discharging them fron the furnace, moreover with control and measur- ing apparatus, sound and flashlight indicators,, Uniform heating of the rails over their whole length can be obtained by ~continuously moving them forward and backward at a rate of 4 m/min, The Ivardening ccnLauier of 30-ton capac- Card 3/8 S/133/61/000/002/008/014 Volumetric Hardening of Rails in an Industrial ... A054/AO33 itY is equipped with oil conduits, air piping for the mixing of oil, sup- ports for the rails, steam pipes for producing a vapour curtain when the oil is combusted. Above the container a welded metal beam construction is sus- pended. It is supplied with a roller runway and drive for lowering and lift- ing the beam. On the beam a cover is loosely fitted, which covers the con- tainer when the beam is lowered.. After hardening the rail is removed by a winch from the beam structure onto a shelf provided with equipment for the removal of oil vapours, A bridge crane then carries it into the furnace f0 annealing. The uniformity of heating was checked by -electronic potentiome ters, indicating that the heating of the rails in the furnace is constant. _~/ The temperature differential along the rail does not exceed 800C (500C on a average), above 900-9500C it even decreases to 300C, The temperature drop can further be reduced by discharging the rails more quickly and making the furnace longer. Pairly uniform properties of the metal can be obtained by hardening the rail head at temperatures above Ac ~ The heat treatment is carried out under the following conditions; 3 Temperature of heating the rail in the compartment furnace, 0C 900-920 Card 4/8 3/135/61/000/002/008/014 Volumetric Hardening of Rails in an Industrial...

Flat bending in vertical and horizontal planes does not exceed 80 mm and no torsion around the longi- tudinal axis was 0obse~ved. The rails can be heated at a rate of 2 0/sec be- tween 20 and 900 C, despite the presence of screw holes. Cracks formed only after hardening in oil containing much water and when annealing was delayed after hardening. The comparison of characteristics of heat-treated and non- heat-treated rails show that the former are superior, attaining the values found in chrome-vanadium steel rails: Card 5/8 S/133/61/000/002/006/014 Volumetric Hardening of Rails in an Industrial- A054/AO33 &s &B aK dB kg/sq mm kg/sq mm Y% kgm/sq om mm volumetric-hardened rails 79.5-97.0 126-131 11-8.3 41.5-33.5 3.7-4.5 3.2-3.3 rails without heat treatment 44.0-45.4 83.5-87 11.7-9.5 15.8-19.2 2.0-2.2 3.9-4.0 The test rails were laid on the Sverdlovsk track, in heavy-duty sectors, in curves, and show great resistance to wear. Equipment for the heat treatment of the total Soviet rail production (1.2-1.5 million tons a year) for rails 25 m long, will be designed. The heat treatment costs about 10 rubles/ton, so that it is much cheaper than using alloyed steels. There are 5 figures and 2 Soviet references.

Vol 1, Moscow Izd-vo in. lit. 1955, pp 165-200 ABSTRACT: The ores of all the larger deposits consist of limoni% siderite, hematite and magnetite. From the point of view of iron production, large reser,~es of chromium and manganese are of intere_-,;. They are characterized by their high iron content as compared with chromium and manganese, the latter being found in braunite and acobsite. The possibility of extracting titanium rom the iron ore rich in this element was investigated, i Card 1/5 15-57-10-14278 Iron Ores in the Union of South Africa (Cont.) The following genetic classification of iron locations was adopted: magmatogenic (ma~matic segmWtions, contact-metosomatic deposits and vein occurrences), depositiona1 occurrences of replacements and secondary concentration (Upper Lake type) and, finally, laterites, iron caps and other surface formations. The article subdivides the ores into iron ores proper containing Si02, P, S, Ti, Mr, and CaO, and into chrome-iron ores, manganese-iron ores and titanium-iron ores. The industrial and economic aspect of the iron occurrence is briefly described. Of economic significance are the concentrd- tions of rich hematite-magnetite ores, titanium-bearing ores, banded iron deposits, itabirites, gray iron ores, iron bearing sandstones, ochres, limonites iron spar and cemented black sands. The main occurrences (in je'scending order of importance) are: Tbabazimbi ' (under operation), Pretoria-Townlends (extraction temporarily sus- pended), Zishen (r6aft-for exploitation), Prestwick (in operation), Early, Malalane, laokoveld (southwestern Africa)I Postmasburg (large reserves of'iron and manganese ores) and Bushveld (giant or Card 2/5 15-57-10-14278 Iron Ores in the Union of South Africa (Cont.) large reserves of titanium-bearing iron and chrome ores). Genetic types of these sources are briefly described. Ore fields of Taba- zimbi and Postmasburg are associated with the Upper Lake type. According to the author, the Postmasburg complex originated as a re- sult of hydrothermal metamorphism of deposits. The question is posed of the nature of regional hydrothermal activity which is,not related to the active magmas.* Iron-manganese ores of Otzhonsondu and itabirites of Windhobk and Wolfish-Bay are of the metamorphosed sedimentary type. Sedimentary deposits originated as a result of two processes--the chemical and the mechanical concentration. Tita- nium-bearing iron and chromite ores of the Bushveld complex are associated with the type of magmatic segregations. Not a single one of the genetic concepts has been proven. Geological and structural features of the individual occurrences and of their industrial-eco- nomic value are presented in three appendixes, each of which repre- sents an independent article. The exploited deposits of ?Mbazimbi' are the banded iron ores and hornblendes of the Precambrian dolomites of the Transvaal series, which are penetrated by gabbro and granites Card 3/5 Iron Ores in the Union of South Africa (Cont.) 15-57-10-14278 of the Bushveld magmatic complex. Some of the extracted hematite ores contain no less than 57 percent of iron and no more than 15 percent Of Si02- Potential reserves of such ores irf Thabazin6i corr- prise approximately 14 million tons, while the total reserves of the entire ore-bearing areas reach 72 million tons. The Zishen location is related to the Criquatown i series, which consists (from bottom upward) of banded iron deposits, yashmas and tillites. The series is represented by siliceous breccias containing manganese, and by dolomites which are stratigraRhically correlated with the dolomites of the Transvaal series. ocks of the 'Criquatown series occur in flat brachianticlinal and brachisynclinal folds. Intrusive rocks are represented by dolerite. The deposits were produced as a result of the secondary enrichment of iron-bearing sediments from which silica and alumina were removed. Three types of hematite ores are: common-ba~-ded ' iron ores, iron-bearing conglomerates, and iron-bearing basic shales. Proven resources of ore comprise 160 million tons, while proven and suspected ones total 300. million Card 4/5 Iron Ores in the Union of South Africa (Cont.) 15-57-10-14278 tons* Geologicallys the ores of the PostmaBburg are similar to those of Zishen. Total resources of this locality are estimated at IvOOO tons. Iron producing localities of southwestern Africa are sedi mentary (KawaB. Okava., Gagapye,, Kookoveld,, Gazeneirab,, southwestern Windhook, WolfiBh-Bay, Otzhosondu, In the Ketmanakhon region) and the metasomatic (Kalfeld and Okopusu). Geological aspects and qual- itative description of the ore are briefly presented, as are the estimates of ore reserves in each locality; these estimates ranging from the tens to the hundreds of millions of tons Card 5/5 .a- Z.A.

The reporting of both diseases as hemorrhagic fever makes a study of the epidemiology of these diseases in the period under consideration somewhat difficult. In 1953-1964 there were 723 cases of "hemorr- hagic fever" in Bulgaria with a mortality of 24.6%. Of these, according to the authors' data, 327 were cases of hemorrhagic nephroso-nephritis with a mortality of 22.8%. Hemorrhagic nephroso-nephritis occurredin nine regions (okrazi) of Bulgaria in 1954-1964. The Pazardzhik region with 76 cases was affected to the greatest extent. The greatest incidence during a year was in July. The age group 20-29 showed the greatest frequency of infections (45 cases out of the total of 127), followed by the age group 30-39 (36 cases). Of the 1,-7 persons who had the disease, only 3 were women. The highest incidence was among forest workers, followed by construction workers in mountainOU6 areas, farm workers, and geologists and miners. Tables, 2 references (both Bulgarian).

It has become particularly important in recent years in connection with the continuous contamination of the air by radio- active substances emitted during nuclear explosions, which to some extent alter the ionic balance of the atmosphere. The most widely used instruments for studying the ionic composition of the atmosphere are specially designed ion counters through which a current of air is drawn and which essentially consist of a capacitor producing an electric field between its plates. The ions in the current of air are deflected by this electric field and are captured by one of the capacitor plates. By measuring the charge received by the Card 1/6 condenser and the amount of' air drawn through -it, and 6 9 4 3.5 S/139/60/000/01/009/041 E032/E414 On the Measurement of the Ionization of the Atmosphere knowing the ionic charge, one call determine the number of ions per cc of air. The ions can be separated into a number of groups according to-their mobility. In order to measure the density of ions having a given mobility, the capacitor must work under saturation conditions for that particular group, It call be shown (Ref 1, 3 and 4) that this condition is satisfied when the velocity of the gas flowing through the counter is less than a certain critical value, which is given by If IT Cy k where C is the effective capacitanceq y is the potential difference between the electrodes and k is the limiting mobility of the ion group under investigation, In the case of low-mobility heavy ions, the saturation conditions are difficult to fulfill. In practice. portable instruments cannot work with potential diffevences Sveater than 300 to 400 --rolt. Card 2/6 On the other hand, the capacitance can be increased by 694,35 S/139/60/000/01/oog/o4i E032/E414 On the Measurement of the Ionization of the Atmosphere increasing the length of the plates and reducing the distance between them. Accordingly, some workers (Ref I and 2) have employed instruments in which the capacitance is of the order of some hundreds of cm, while the length of the electrodes is of the order of one metre. Such instruments are rather heavy and inconvenient in field work. However, it can be shown that the limits of the increase in the capacitance must be deduced not independently, but in conjunction with the capacitance of the electrometer which measures the charge collected by one of the electrodes, In facto the charge received by the electrode is given by q = WNte, where N is the number of ions of the given mobility per unit volume, t is the time during which the air is drawn through the instrument and e is the ionic charge. However., the change in the potential measured by the electrometer is given by q Card 3/6 C + Ct, 6914-J5 S/l3q/6o/ooo/oi/ooq/o4i E032/E414 On the Measurement of the Ionization of the Atmosphere where Ce is the capacitance of the electrometer. Substituting for q and bearing the expression for V in mind, one finds that 4lTkeN,#t I +ICe C Moreover, the sensitivity of the ion counter is proportional to the change in the potential per unit time. The change in the readings of the electrometer per unit time is proportional to the sensitivity of the electrometer y expressed in scale division per volt and the change in the potential per unit working time, ie (X t The sensitivity of the ion counter can then be defined Card 4/6 by 69435 S/l3q/6o/ooo/oi/ooq/o41 E032/E414 On the Measurement of the Ionization of the Atmosphere I 4T[kepy 1 1 + Ce C This formula shows that the sensitivity depends not on the capacitance of the counter itself but on the ratio of the capacitance of the electrometer to that of the instrument. Clearly, maximum sensitivity is obtained when C is much greater than Ce- It is also clear that as soon as the ratio of the capacitances is of the order of 0.1, the sensitivity will not be -very dependent on C, so that there is no point in increasing the capacitance of the instrument any further, Thus, by choosing an electrometer having a small capacitance, it is possible to design an ion counter using a small capacitator, and a simple and portable instrument is achieved. The author has designed a number of ion counters which are based on the above Card 5/6 considerations and their performance compares very t-1K 6913" S/139/ 0 000/01/009/041 E032/E414 On the Measurement of the Ionization of the Atmosphere favourably with other countevs described so fart in spite of the fact that the latter counters have much greater capacitances.

The action of molten metal on steel is explained by two theories; by diffusion processes~ or by adsorbtion. A liquid medium readily penetrates into microscopic cracks in the steel surface, and the wedging action so caused gives rise to massive crack formation. The influence of liquid brazing metal on tensile specimens is given in Table 1. The specimens were tested at tempera- tures from 9250 to 10000C after brazing metal had been ap lied to the specimens. These specimens were tested at 2.~ mm per minute rate of deformation. Fig 1 shows how extension to failure is greatly reduced for specimens tested with liquid brazing metal in contact with their surface - the top specimen in the figure is without brazing Card 1/4 metal. Results of tensile tests at other rates of SOV/122-58-12-21/32 Crack Formation when Brazing UX8N9T Steel with L.62 Brazing Metal deformation are given in Table 2. At lower rates of deformation, or at higher test temperatures the loss in strength and plasticity of the test specimens in contact with liquid brazing metal was much more severe, At high rates of deformation the presence of liquid brazing metal has little or no effect - the speed of crack propagation through tensile stresses being gre r than Vie rate of ,a te penetration of the liquid brazing beta.1% 4Conta~6t with liquid brazing metal causes considerablereduction in creep strength as shown in Fig 2. The influence of different methods of heating during brazing operations was studied, using oven heating9~'high freqtfercy heating and heating by gas flame. H.F. heating and h6d'ting in an acetylene flame set up variable thermal strppses at the metal surface,, and the failing loads o..f teA nieces heatred in this way while in contact with liquid brazing metal was very low. Influence of work hardening befere brazing was also studied. In some cases, work harqenecr sAecimens Card 2/4 which were heated by H. F. , or by gas flame; fractured without application of external load. The rapid heating by these methods does not stress relieve the work hardened SOV/122-58-12-21/32 Crack Formation when Brazing M18N9T Steel with L.62 Brazing Metal material before it comes into contact with the liquid brazing metal. Similar tests on specimens in compression showed little influence through contact with liquid brazing metal. Tensile tests using various fluxes showed little influence of flux on reduction of strength, nor id preliminary plating with copper or nickel to a hickness of 3 to 5 microns prevent these effects. ~In order to minimize the crack forming effects of contact with liquid brazing metal, it is suggested that parts should be heated to a constant temperature in electria ovens with ordinary or with reducing atmospheresq or in salt baths. With H.F. heating or with gas flame heating., the time of contact of the liquid brazing metal should be kept to a minimil , and the metal should be applied after re-heating the steel to an uniform temperature of Card 3 700 - 9000C, and repeated application of the brazing SOV/122-58-12-21/32 Crack Formation when Brazing Ual8N9T Steel with L.62 Brazing Metal metal should be avoided. Rigid clamps and fixtures should be avoided. The problem cannot be completely solved -without development of new brazing materials - a new solder, designated PZhL-500 is already being widely used.
