The following relations are obtained 1/2 1/M _M M Ta . (~o ) , to % T I W % T and agree with the available experimental data. The results hold trve for all crys- tals in which the deformation occurs via generation of glide bands and their lateral gruwth, particularly for metals with body-oentered cubic lattice. They also hold for polycrystals in which the deformation takes place by passage of Luders bands. Orig., art. has: 10 fbmilas.

The temperature ranged from 550 to 1,1000C. The date of Table 1 and Figure 2 shows that-the maximum 0weight increase is at 7000C. In the interval between 550 and 800 C the reacting substance consiste of tin oxide, sulfate, sulfides and metallic tin. Above 8000C the tin sulfate is practically absent. This corresponds to the results published in fRef 42 that S02 oxidizes metal sulfides and reduces sulfur at the same time. At low tempera- Card 1/2 tures prevail sulfates, at higher temperatures oxides.

At a higher temperature 90COC, the oxide and me- tallic tin content decreases which indicates that reactions (1) and (2) are practically absent. It is also shown that molecular ra- tions of magnetic iron oxide and tin sulphide at all temperatures and Sn : S ratios equal V3 which indicates that the principal reac- tion in the sulphidation of stannous oxide with iron sulphide is: 4SnO + 3FLS = 3SnS i- Fe304* Sn. C---.rd 2/5 S/080/61/034/007/007/016 Investigation of the reaction D223/D305 The isobaric-isothermal potential of the above reaction for tempe- rature T is given by Z = 8709 - 46.46T lgT - 1~36 - 10-3 T 2 -t 111.2 T. This shows that reaction (3) could take place at 400 00 and higher temperatures which agrees with experimental data. Hence it is ob- vious that for the temperature interval 600-7500C, the decomposi- tion of SnO follows reactions (1) and (2) with the simultaneous reaction (3), At 7500C and higher, only reaction (3) takes place perhaps with a negligible extent of slight side-secondary reac- tions. The interaction of stannic oxide with iron sulphide was in- vestigated at 6009 7009 900 and 10000C for 15 and 60 minutes and with charges containing 1.5 9r- of Sn02 and 0.9 gr. of FeS which corresponds to equiatomic proportions of tin and sulphur in char- ges. The results are given in tabulated form. The products of in_ teraction of Sn02 and FeS obtained were tin sulphide, magnetic iron oxide and sulphur dioxide hence the reaction is as follows: 5SnO2 + 6FeS - 5SnS * 2Fe 304 + SO2 (4) Card 3/5 S/080/61/034/007/007/016 Investigation of the reaction ...

The system (C (S)) uses binary counting, since if using decim--.l count- ing, the number of the distributor ele~aents would have to be 'Lhat of the number of scale divisio-,is of the measuring instrument, for an accuracy of measurement equal to that of one scale division. T'he remote measurement system consists of a transmittcr, remote-control Card 1/2 27367 S/19 6 1/000/00 3/031/04 5 A discrete remote control system.,. D20IX306 and remote-signalling arrangement and of a receiver. The previously developed contactless remote control and signalling arrangement is used, with the number of distributor elements equal to the number of binary number digits. The sensingr device may consist of any mea- suring instrument with angular output indication. The transforma- tion of this indication into the code is made by means of a perfor- ated disc and a photo diode 6 digits counter. The Grey binary code is used, as the normal binary code might lead to considerable errors when going from one digit to another. The receiving installation has a decoder and a receiver - milliameter. The decoder has 6 ccntact relays and 6 resistors. The transposition of the Grey code into a binary one is achieved by a relay circuit. The system of remote measurement does not require any special communication chan- nel and depends little on its state. The accuracy of measurements is arbitrary since it is determined by the number of distributor elements. 2 references..

The telemetered quan- tities are measured intermittently by means of an analog to digital (Gray code) converter of the slotted disc type. Several schemes for Gray to binary code conversion are described. The pulsed output C'"d 1/s ACCESSION NR: AT4040443 of the analog to digital converter is sent to the line by illumin- ating photodiodes with commutator lamps. The telemetered pulses are converted into dc whicb is measured by the receiving instrument. The decoder used for this purpose is described briefly. The accuracy of the over-all system is determined by the number of binary digits employed, and the circuitry errors.are minimal. The system'has passed laboratory tests and is presently in operation.

In-ta metalla i gorn. dela AN GruzSSR, 1957, Vol 8, pp 43-51 ABSTRACT: Test heats were run in a two-electrode, single-phase. 30-40 kw furnace, magnesite lined, with a power density in thelicarth of 2.7-3.6 k,.v/drn?-, employing a charge of Mn ore or converted Mn slag and time, the reductant employed being Si-Al with 36.061o Si arid 44.02% Al. It is established that when Mn ore is employed the oxidation of the Si proceeds more intensively and results in < 1% Si content in the alloy. This is explained by the presence of Mn304 in the ore, whereas the slag contains MnO only. Optimum results in terms of Si content in the alloy and Card 1/2 MnO content in the waste slag when Mn slags are employed are 137-58-6-11658 Use of Alurninurn-silicori (cont.) attained when 0.5-5 mm Si-Al is charged onto the -urface of the slag intro- duced. The C contents of the alloy fluctuated from 0.09 to 0.34%, the higher values being the result of periodic immersion of the electrodes in the slag, which cannot be permitted to happen when the standard three-phase furnaces are used. The concentration of P in the alloy was in direct relationship to the [P ]in the charge, as Al is highly reductive of P205. When Mn slag is employed, tP) did not exceed 0.08%. The [Mn) in alloys smelted from Mn ore attained 84.64% while that in metal smelted from Mn slag attained 85.5711u. Calculations of unit ore consumption per ton of alloy are presented, although it is noted that these figures may be cut down, possibly, when larger furnaces are used for the smelting.

TITLE! Electric Smelting of Silico-Aluminum From Coke and Tkibuly Shale Cinders PMIODICAL. Tr, In-ta metallurgii AS Georgian SSR, 1958, Vol 9, PP 59 - 68 ABSTRAM The authors investigated the possibility of obtaining 31-Al from the coke and cinders of Tkibuly shales. The cinders contained (:Ln %): SiO 54.9, A1203 30 1 Fe2o 10.8. The smelts were carried out L a one-phase elec'tr'ic furnace of 175 kva capacity with magnesite lining. An alloy of the following compositlon was obtained (in %): SI 39.8, Al 30.8, Fe 26.79, The alloy can be recommended to be used as a complex deoxidizer in steel production and as a reducing agent to obtain Fe-alloys by the metallo-thermic method. The consumption of electric power under industrial conditions is 8 - 9,000 kw-hrs/ton of Si-Al; the cost of Si-Al obtained on the base of Tkibuly shales is lower than that Card 1/1 of 75% Fe-SI. V,B.
