In the past, many methods for using peat as a boiler fuel have been tried, but. e these experiments failed, since an economic and stable firing of,peat could not be achieved. Only the pneumatic stokers of TsKTI, which were based on: Card 1/6 the whirl principle of A.A. Shershnev, had some SOV/143-519-2-10/19 The Application of Cyclone Stokers With Liquid Slag Removal for Firing Cut Peat success and to-ether with the shaft-mill method, they found the most wide-spread application. The cyclone stokers, suggested by Professor G.F. Knorre, are the latest development in.this field. The shaft-mill msthod has a heat liberation value of 150-103 kcal/ M3 hy while that of the TsKTI stoker is 120-10 kcal/ m h, which is relatively low and therefore large stoker volumes are required. -In addition, soot traps must be installed, since about 85% of the peat ash. are carried out of the smokestacks with the first method and almost 100% with the TsKTI-stoker. The large stoker volumes and the soot traps of the pre- sently used methods are not suitable for a large- scale conversion of boiler stokers to use peat as fuel. Therefore, only 2.09 million tons of peat were mined in the Sverdlovsk Oblast', in 1957, while' the annual output could be around 40-50 million tons annually, since the peat deposits in this area Card 2/6 alone are estimated at 4.5 billion tons. The Ural SOV,/143-59-2-10/19 ,The Application of Cyclone Stokers With Liquid Slag Removal for Firing Cut Peat peat is composed of small particles those having a size of 3-4 mm amount to only 10-15 and its ash content is 8.9-9%. The melting point of the ash varies between 1050 and 1170 C. The moisture con- tent changes annually; in 1956 it was 46.3%, while it decreased in 1957 to 42%., Mining oAe ton of peat costs presently 16-18 rubles, but this cost could be reduced with large-scale'mining methods. For using peat as boiler fuel on a large scale, the authors recommend a cyclone stoker with liquid slag removal. However, there are no publications available on data for firing peat in cylone stokers. According to data furnished by M.A. Nadzharov ~R`ef 57 for coal- fueled cyclone stokers, the slag viscosity must not exceed 250 poise at 14000C. Calculations showed that with a 50% moisture content of the Deat, temper- atures of only 1400-15000C could be obtatined at the 0 outlet of the cyclone stoker,,even if ho~ air of'400 Card 3/6 C was blown in, while theoretically 1640 0 were re- SOV/143-59-2-10/19 The Application of Cyclone Stokers With Liquid Slag Removal for Firing Cut Peat quired. The authors had the opinion that such a temperature would not provide a stable and continous removal of the liquid slag. When burning peat in a cyclone stoker with liquid slag removal, the main problem is to provide a temperature in the combustion chamber which exceeds the melting temperature of the slag to a considerable degree. The authors perform- ed the same calculations for peat with a moisture content of 32-35% which showed that a-tempe .rature of 1706-1733 C could be achieved when blowing in air at 350-400 00. Figfire 1 shows the-graphical pre- sentation of the calculation results. A footnote says that the slag viscosities of various fuels are under investigation at UP! - Urallskiy politekhni- cheskiy institut imeni S.M. Kirova (Ural Pollytech- nical Institute imeni S.M. Kirov). Based on the theoretical calculations an experimental cyclone stoker was built at UPI, as shown by figure 2. A Card 4/6 fan was used, powered by a 5-0 Inv asynchronous motor, SOV/143-59-2-10/19 Tlie-Application of Cyclone Stokers With Liquid Slag Removal for .Firing Cut Peat which produced a pressure of 2,000 mm water column at 3,000 m3/h air consumption. 0The air heater pro-* vided temperatures of up to 500 C. The combustion chamber of the cyclone stoker is shown by figure 3. The peat used for the experiments was preliminarily dried and had a moisture content of 15-20%, its ash content was 11%,with 62-69% volatilematter. -Its heat value was 3900-4100 kcal/kg. The peat was fed into tfie cyclone-stokeE at a rate of 450 kg/ an air temperature of ~50 C, whereby heat liberat' n (V 9-1 ,values Q/ ts Q kcal/m3h and Q/F ts = 7.5-10 kcaj_/m3h were obtained. The'gas Semperatures in the cyclone stoker were 1500-1600 C while the surface, temperature of the liquid slag flowing out of the 0 tap hole was 1380-1440 C. Pyrometer errors must be taken into consideration, thus the actual temperatures were somewhat higher.

'11io transfer function for the lioino.-lencous earth path is approximated by parallel combination of compensated IT- and C- circuits followed by a linear mixer.

In case of low conductivity in the upper layer the approximating circuit is a L- circuit followed by a delay line and mixer combination to simulate the multiple signal reflections which arise in such paths. A combination of these circuits was used to construct a path simulation system. INTeasurements of the response of this system using simple signals (t), u(t) cos v-10t, u(t) sin k-j and S (t) u (t) sin as well as arbitrary pulses, showed a deviation of 5% or less from true values. It was.concluded that the initial pulse form (at the antenna) is very imporLant and that small changes in the iniUal pulse form can influence the final response very significantly. For this reason, the transient characteristics of the antenna must be considered in detail when computing the transient response of the ground wave propagation path.

Fo-r flo- tation, the ore must be crushed (70-80% below 200 mesh), suspen- sion density should be 250-300 g/1, and 0.8 Kg,oleic acid, 1.2 Kg Syntonpon CP and 0.45 Kg water glass must be added per ton of. ore. Further chemical processing.of the barytic concentrate in 1956 gave rise to a number of problems as the materials could not be utilized directly due to the unfavorable chemical composition and fineness; tl~us even direct reduction to BaS proved impossible because of excessive (> 70.6 %) Fe2+ content. It was found that at least 90% BaS04 and not more than 1.5% Si02 and 5.3% R20,3 were Card 2/4 P/OlLF/61/040/006/001/002 Baryte processing, D253/D302 needed for successful reduction. A baryte extraction plant was opened on 1.7.1957 and continues production to the present day. The chemical treatment processes are then 'described. The pro- cesses are fairly costly due largely to acid corrosion of the, equipment. On the chemical side, the yield of baryte concen- trate is 0.02 - 0.06 t/hr/m3 of extraction vessel and requires 2'3 Kg of 100% H2SO1+ per Kg of Fe dissolved. The losses amount to 5.4% during removal of siderite and a further 1.6% in fines. Additiox~al losses include r,,3% during the reduction to BaS, as dust. It is-estimated that 2000 Kg of pure concentrate needed for 1 t6n of BaS. Some of these losses may be avoided, e.g. by more efficient dust catching or granulation of the reduction mixture and general improvements are the future. Methods of bleaching the flotatiQn concentrate with acidic wastes from the production of titania white were evolved in 1956-58 for ores containing no elemental C. Standards for such concentrates are the same as for the reduction., A continuous bleaching pro.- cess was devised in 1959 and will be put into operation in 1961, Card 3A P/014/61/040/006/001/002 Baryte processing... D253/D302 employing the same equipment for both chemical refining and bleach- ing. At present BaS production is carried out in the same equip- ment as used for chemical refining. In the.latter, 1.5 t of concentrate are treated with lm.3 of waste acid at 900C, for 1-2L hours. In multistage flotation dark foam collects in the first few tanks and light in the last.. The product s consist of a light 'suspension (-1800 g/1) and a dark foam containing 1-15% of baryte concentrate. The suspension is filtered, washed, filtered again and converted to BaS. The fines yield bleached baryte and pigment. Concentrate collected by,the foam is reduced to BaS. Refinement of baryte for the petroleum industry, by the removal of flotation reagents and finer granulation, is now.being investigated. Large scale production of baryte concentrates and of a wide range of Ba. compounds is expected in the near future. There are 1 fiaure and 2 tables.

No. 5, P. 167- =T: The 6s-tav jadern& fysiky (Institute of Nuclear Physics) built a 100-cbannel amplitude analyzer with a nickel-wire magnetostriction memory.* The, apparatus is of cabinet design with power sources mounted in the lower half and two vertically mounted drawers of the apparatus.properin the upper half. Radi ation hitting the detector is converted to electrio pulses, whose amplitude cor- responds with the energy of the radiation. The-analyzer directs these pulses Into the individual channels according to their respective amplitudes. The ap- paratue operates on the principle of amplitude-to-time conversion with pulses being stored in a magnetostriction memory. The spectrum measured is indicated on a screen in the binary system in the form of permanent bright spots. Ampli- fied pulses are fed to the analyzer where they are,furLher amplified and shaped. Subsequently, they pass through a gate to the comparator cirmit. Here their amplitude iz compared to a linearly increasing, periodically repeating sawtooth Card 1/3 151Z 6Q/OW/005/OC4/0Q4 100-Channel Amplitude Analyzer A201/AOr26 voltage. The result obtained is a time period defined by the starting point of a sawtooth and the point of agreement. The pulse obtained is recorded in the channel corresponding with the established time period. The number of-channels is variable by a switch in 4 stages.(60. 80, 100, and 120 channels). The memory co-Y)s:Lsts of a 6.5 m long, 0.15 mm diameter nickel-plat-ed wire. 1 - D ts delay is 1,300/Asec~- it. is capable of storing a maximum of 1,200 pulses with a repeating rate of I Me. Additional measurements, e.g., with a two-crystal sum spectrome- -,~er, are made vossible by a switch-cor%rolled gating circuit. Pulses of tegra.ted spectrum are extracted from -i independent output terminal. The read- out of the spectrum from the screen ij facilitated by the division of channels into groups of five, and by a transparent grating with numbers indicating the channel capaci-l~y at a given point on the screen. However, this arrangement is, far frc~m being ideal and, therefore, an automatic readout attachment with an e1-, ectric calculating machim. is being.developed.
