TITLE- Electrothermic Recovery of Zinc at the Belovo Zinc Plant (Elekt rote rmicheskove poluchenive tsinka na Belovskorn tsin- I~zovom zavode) PFRIODICAL: Byul. tsvetn. metallurgii, 1957, Nr /-I, pp 20-23 ABSTRACT~ A pilot-plant installation having in clectrozhermic furnace of 150 kw power was emploved to rnelt sintered Zn concen- trates of the following % composition- Zn 57-60. Pb 0.7- 1, Cu 2-2.3, Fe 6-9.4, Cd 0. 1 -0. 13, CaO 0.9- l.q, _\MgO 0.7-0.8, SiO2 3.4-4.7, S 0.3-1. The charge (composition of the raw mix: 60 kg sinter, 12-13.5 kg coke breeze with 12-20% moist- ure and 14-20% ash, and 5 kg calcined lime) was mixed in a drum mixer, calcined for 3 hours at 800-8500C in a reducing atmosphere, 15-210 ko return dross was added to it, and the whole was charged into the furiia,-e through a bell-shaped scaled charging device. Smelting was at 68 v and 2250-2500 Card 113.1 amps with graphited electrodes immersed 200 mm into the slag, SOV/ 137-58-7-14601 Electrothermic Recovery of Zinc at the Belovo Zinc Plant the bath depth being 400 rnm and the slag temperature 1350-14000. Optimum process conditions were assured in reducing the basic quantity of Fe and the formation of Fe-Cu alloy in which the noble metals were concentrated. Slag was tapped once each shift, the Fe-Cu alloy once every 10-20 days, The Zn gases and fumes were taken off the furnace through an aperture in the side- wall and an inclined gas line in the condenser (C), lined with magnesite brick in its lower portion and a floor made of carbon blocks. The tempera- ture in the gas line was sustained at 800-9000 and in the C at 600-6500. The gases left the C at 350-4000 and proceeded to a scrubber irrigated with water. The extraction of Zn as metal having the following inclusions (lo), Pb 1-1.5, Cd 0.1-0.13, Fe 0.1-0.5, Cu 0.01-0.02, was 60-707o. 15-207o of the Zn was trapped in the scrubber as blue powder enriched with up to 0.65o Cd. Up to 30% of the Zn was in the returns in the form of dross precipitated in the C. The dross and blue powder contained 88-93% Zn. When the lower portion of the furnace was lined with magnesite and cooled with water to form a lining hardened on the wall, a furnace campaign lasted > 2 months. Losses of Zn in the slags came to 1.5-6%, and recovery of the Cu in the alloy was 90-98%. -. Zinc--Reccvery 2. E-'eczric Ye.Z. Card 2/2 SMIMLIN, I.D., kand. S0l'l3kOkllOZy!L.Vatvennykh nauk.

Red muscles have a higher nucleic acid content than white muscles. Fatigue-producing work lowered the level of nucleic acids in both types of muscle because of a reduction of the amount of MA, while the D'Dlk content did not change. The extent of reduction of the RNA content was more pronounced in white muscles'than in red =scles.'.Presumably the higher nucleic-acid content of rad muscles and the more sparing use of MM by them is Card. - 1/? ACCESSION NR. A?4ol4378 associated with the higher capacity for work and lower.-susceptibility to fatigue of these muscles. Small differences in the total P. acid-soluble phosphates, and phospholipid content-of red muscles as compared wiUf white muscles were also observed after fatigue-producting work: the P and acid-soluble phosphate content decreased as a result of fatigue to a greater extent in red muscles than vhite muscles, while the phospholipid content remained unchanged in red muscles and increased in the majority of cases in white muscles.

Forging pressures of 27-30 Icg/M2 were used for the expulsion of oxidized metal from *the welds. Good results were obtained when the butt-welded A!~-,3114 pipes wore of different . wall-thickness: 40 x 1; 41 x 2; 42 x 2 mm. Further i:mprovement was achieved with the use of separate current lines for the upper and lower electrodes; the current density was 200-300 amp MM . With this tech-: nique it is possible to weld together thin-i-ralled pipes with thicknoss-O.D ratios up to 1:50 and higher. Sample strips cut off the welded connections were tested. The tensile test showed that failure occured in the basic metal outside the thermal, ,affect zone of welding. According to metallographic analyses the butt-welded Cord 1/2 -C ACCESSSION "J'R: AP4040697 structures were uniform in structure and free of inclusions or oxide films.

A, TITLE: Pin tube electromyograph PER:ODICAL: Akademiya nauk Kazakhskoy SSR, Vestnik, no. 11, 1960, io4 - 1o6 .MT.: The subject myogrd~h has been developed at the Instilkut krayevoy patologii AN KazSSR (Institute of Regional Pathology of ttie Academy of Sciences of the KazSSR)'because of the absence of modern myographs on the market, The new features in it are the pin tube amplifier for.measurements of biological cur- rent-s, ard electronic voltage stabilizers (Fig, I and 2). Actually, the amplifier had been designed by V. A. Kozhevnikov and,,V. I. Siroko of the Institut fiziologii im. T. P. Pavlova AN SSSR (T stitute of Physiology imeni I, P. Pavlov of the AS US In SR) who used the system.of 4. M. Andrew and of G. Ele-in (both of 1955, the names are given In original t~glish and_German) with octal ("oktal'nyye") base tribes. n th T 1 e-new-amplifier these are replaced by pin-type base tubes ("pal'ohikovyye"). The tubes are operating from a 110 - 220 v network (can also work from a storage battusr~i). The balanced system permits recording without screening off the room from the common interference sources like electric lighting bulbs, CH 250 (SN250) Card 1/0, 25173 S/031/60/000/0 11/007/008 Pin t--:be electromyograph A161/A133 voltage stabilizer, etc. The amplification factor (from input. to electron-ray tabe) is about 1,000,000;- the sensitiviti (input-photo film) 10 /LLv in 1 mm; the frequency band amplified without frequency and amplitude distortions is I 2000 cycles. The principle of the system had been described in 1957 by Kczhevnikov and_Siroki-,, therefore only the new features are mentioned in the article. The four amplifier cascades (Fig. 1) include 6-H2 n (6N2P) pin base zubes. Local -i~ga'14ve feedback between -he I and II cascades could be used in view of the high amplifi~-'at.4_on reserve, and the.zero line drift and the interference level are re- dicpd to minimum. The total resistance in the cathode of the first cascade tube (negative feedback for symmetrical signals)-is high, due to the JI (L~), a 6An (6K4P) t7jbe used. The ampLifier is assembled on a pleyiglas frame ~for it was not pi3sibla to use a metal panel because of interferences), and the frame is fixed on foam T-ubber dampers. The parts of the amplifier are of standard pattern but caref~Aly selected. The tube anodes are supplied from stabilized rectifiers, The voltage stabilizers (Fig. 2) are-assembled in a combination compensa- and parametric system the principle of which had been described in litera - '.;rE in 1957 by I. G. Gol'dreyer (Russian name) and in 1941 by 1. E. Miller (Eng- lig~- spelling).

Ionized air is sent by means of a ventilator across a cylindrical capacitor having an external cylindcr-plate and an internal measuring electrode. A constant voltage, of magnitude dependent on the mobility of the ions. is supplied to the external plate. An electrostatic charge, equal and opposite to the charge of the plate, is then induced on the measuring electrode. When ionized air is sent through the capacitor, ions of a selected mobility precipitate on the measuring electrode. A sensitive voltmeter, graduaied in ions, and connected to a high ohmic resistance, permits a direct reading on the scale. The circuit of the tube voltmeter consists of an electrometric double miniature tetrode 231712 (2E2P) connected according to the bridge balance circuit. The vacuum resistance in glass balloons of the KBM (KVM) type of 1012f) is used as a high resistance and flM (I-M) (or NI-24) microarnmeter with scale (0-50).10-6 a serves as an indicator.

Izvestiya Akademii nauk SSSR,Otdeleniye tekhnicheskikh nauk, Metallurgiya i toplivo, 1959,Nr 5, pp 91-96 (USSR) ABSTRACT: The author mentions the diversity of published opinions on the solibility limits of tungsten carbide WC in cobalt and nickel (Refs 1-8). The object of the present work was the more precise determination of the solubility in cobalt compared with that in nickel and the study of some of the properties of the solid solutions formed. Alloys were prepgred from tungsten- carbide, cobalt and nickel powde sj~(Table 1). For solubility determinations mixtures of cobalt with 2, 1+7 61 109 12, 157 18 and 20 weight % WC and of nickel with 61 157 18 and 20 weight % WC were prepared. Compacted cylinders 18 mm in diameter covered in graphite parti.cles were reduced in a hydrogen stream at 700-8000C for"5 hours. Alloys were prepared by fusion and Card sintering for 1-2 hours at 1200-11+50 OG in a laboratory 1/3 vacuum furnace, followed by cooling in the furnace at about 200-300 OC per minute to 700-800 OC. 67802 SOV/180-59-5-14/37 Solubility of Tungsten Carbide in Cobalt and Nickel Carburizing (to make good the C-deficiency of the WC preparation) sintering of specimens at 1250-1450 OC was effected in a current of hydrogen in contact with carbonaceous material. Microstructural investigation showed that the WC-Co alloys with under 12% WC contain a single phase (Fig 1) and those with over 12%, two (Fig 2). Carburi4ing treatment led to the appearance of lamellar gra hiteVinclusions (2, 4 and 6% WC) and also (10) 12, 15--a-nd-18% WC) a WC phase in a eutectic. Rapid cooling in water gave a WC + Co-phase + C eutectic at grain boundaries (Fig 3); cooling in the furnace gave the corresponding two binary eutectics. The author concludes that with excess carbon the solubility of WC in cobalt at the eutectic temperatures does not exceed 10 wei ht %. The authors' previous work (at VNIITS in 1954-59) indicates (Fig 4a) that a higher solubility is obtained w1th lower carbon contents. For the nickel Card alloys prepared by vacuum sintering at 1200-1425 OC rapid 2/3 quenching was adopted. Fig 5 shows the absence of WC- phaseparticles and the presence of carbon inclusions in the 1% WC alloy vacuum melted at 1380 OC. Fig 6 shows 5_67802 SOV/180-59- 14/37 Solubility of Tungsten Carbide in Cobalt and Nickel individual crystals of WO and nickel-graphite eutectic in the 18% alloy vacuum melted at 1350 OC. In 15% alloys obtained under carburizing conditions no WC phase-vas detected. The authors conclude that the limiting solubility of WC in nickel in the presence of structurally free carbon is about 15 wt %. The results of X-ray investigation (including lattice-parameter determinations of cobalt) of WC-Co alloys are given in Table 2; they confirm those of microscopic examinations of the same samples. Fig 7 shows the lattice parameter of nickel in relation to the WC-co tent, the value rising from 3.517 for pure Ni to 3.545 1 for melted 20% WC alloy. Here too X-ray results confirm those of microscopic investigation. Microhardness determinations showed that with increasing WC-content and especially after the appearance of the WC- phase the microhardness rises. Fig 8 shows. the micro- Card hardness vs WC-content for nickel; this was always less 3/3 than that of the cobalt-base alloys.

On the basis of the data of the metallographic investigations and measurement of the shrinkage of the speeimens during sintering, it was established that the eutectic appears for a NbC content of about 0.5 mol %. Consequently it can be assumed IChat the solubility of niobium. carbide in cobalt at the fasion temperature of the eutectic does not exceed 0.5 mol %. This was also confirmed by X-ray data; the lattice parameters of pure cobalt and of the cobalt phase in the alloys containing 0.5 - 3 mol % NbC did not differ.

With increasing carbon or cobalt content the 11 phase, which formed in the solid state, can completely dissolve in the liquid and is then reprecipitated during cooling in the form of coarse crystals. Fast cooling from high temperatures above the liquidus can result in a eutectic structure. With alloys containing 15 and 10% cobalt, lakes of 11 phase were observed after s�ntering at 1450 OC with carbon contents in the tungsten carbide of 5.88 and 5.94 weight % respectively. With increase in carbon content, crystals of n, similar to those in the alloy containing 30% cobalt were observed. Further increase in carbon content in the 10% cobalt alloy resulted in q, phase in a needle shaped or dendritic form in a lace-like pattern. With very low carbon deficit, the 11 phase can be precipitated at the tungsten carbide - cobalt boundary in the alloys containing 10, 15 and sometimes 30% cobalt.

Tests of the alloy VK4V at 750, 500, 250 and 150'C revealed in all cases a very slight tendency to a drop in the bending strength (by 6 to 13 kg/mm ) which did not exceed Card 2/5 2L, 1 -7 --~ '?I! 1116n' P of Allditional TemperLng S/129/61 ' /000/007/011/016 E073/E535 the c' the fluctuations of' the average strength values.

ABSTRACT: The solubility of carbides of the group IV-VI metals of the periodic system depended on the C content in the initial carbides and the. conditions of alloy preparation. The solubility Of M02C, WC, TaC, NbC, TiC. of TiCWC, TaCWC and NbCWC (30 wt. 016 MC and 7,9 wt. 0/6 WC), and of NbCWC (2:98) was greater when melting was in a.helium~akmosphere than in a hydrogen atmosphere and was least. when operating under carburizing conditions. - The maximum solu- bilities in Co in the presence of structurally free C were 6016 WCP 4% Mo2C and 0. 5 inollo TaC, NbC and TiC. The maximum solubility of TiCWC was 0. 5% and Card 1/2 MYZNIKGV, V. (Kharlkov); MOSHNICHEINKO, M.
