TITLE: Corroal4on of steels -in butyl acrylake and acrylonitrile 11~iiimich-skaya promyshlennost', no. 5, 1962, 067-68 TEXT: The studies were unlertaken in connection' with the ~iroduction of rubber by emulsion polymerization of commercial butyl acrylate M (containinp, I of hydroquinone and 0.12-3.0 of acrylic acid) and 97 -', acrylonitrile (II). The corrosion of carbon steel CT-3 (St.3), chromium steel A13 (Kh13) and Ni-Cr steel 1X181497 (1Kh18N9T) was studied at room and working tenpqratures in the liquid and gas phases and at the interface. (I) St-3 can"be used ,,;ith standard I, but if the --crylic acid concentration exceeds 3 -'-1Kh18N9T should be used. In a 100-hr test at 980C in aqueous solutions of acrylic acid (3.0-0.1 1/j by 7ieifrbt) the corrosion rate of St.3 vas from 4.B8 to 22-55 mm/year, but resistant. ExceDt for the Ni-Cr steel, agitation incre--sed the co.rosion rate. (I!) Commercial II is neutral and noncorrosive, but becomes acid and Card 1/2 61/064/62/000/005/002/002 Corrosion o itteels in butyl... 3 144/Bl3a slightly corrosive when boiled or agitated. Normally St.3 can be used; with hiah-purity products, horwever, Ni-Cr or Cr steels are recommended for precision parts. Further tests'revealed that even corrosion-resistant steels are affected, if they are only in contact with the vapor. This can be prevented by Ureasing. M109T proved to be fully resistant. The polymerization was not affected. There are 4 tables. Card 212 S/064j62/000/001/008/008 B110/B138 AUT HOR s Labutin, A. L.- TITLEt Scientific-technological conference on the prevention of corrosion in aggressive media PERIODICAL: Khimicheskaya promyshlennost', no. 1, 1962, 75 - 76 TEXTs Between Hovember 29p and December 1, 1961, a conference was held on the prevention of corrosion in aggressive media, in the Leningradakiy Dom nauchno-tekhnicheskoy propagandy (LDETP) (Leningrad House of Scientific-technological Propaganda).

Leningrad, 1957, pp 51-55 ABSTRACT: The complex processing of the ore envisages utilization of all its useful components: A1203, S03, Na2O, and K20. The caustic, ammonia-caustic, and reduction m ethods of process- ing the ore are examined. The last yields the best technical and economic. indices. The method is based an removing the S03 in the Al sulfate by reducing roast vAth a gaseous or vapor- izing liquid reductant. The roast gases contain up to 70jo S02. The roasting is performed in fluidized- solids furnaces. Reduc- tion in accordance with the countercurrent principle provides 951o decomposition of the A12(S04)3. The reduced ore is leached at 1000C by circulating caustic solution containing 120 g Na2O/liter. The aluminate solution is freed (,,' silicon at Ca:rd 1/2 1050 and is centrifug6d. As the solution is evaporated after SOV/137-58-10-20696 Complex Processing of Alunite Ore separation of the Al hydroxide, Na and K sulfates are liberated. Sintering of a portion of the resultant sulfates with the return hydroxide and leaching of the Na aluminate derived compensate for the loss of caustic in the pro- cess. The reducing method, with a sintering arm, makes it possible to obtain A1203, HzSO and K?S04' 4' L. P. 1. Aluminum-potassium-sulfate--Processing 2. Minerp-ls--Separation 3.

The experiments were run with kaolin and kaolinized specimens of alunite and bauxite.

To obtain the single side-bE,nd and suppress the carrier wave balanced remodula- tion is used. The side-band shaping device is built in the form of a separate attachment to the normal receiver fox, telegraph work and is switched in between the master .-ener- ator and the power amplifier. It consists cf an AF phone) amplifier, two balanced modulators, a crysta]- heter- odyne and an IF amplifier with crystal filter (Fi&ure 4). In the present instance, to obtain the upper side-band at the output of the transmitter, :he lower side-band is iso- lated after the 1st balanced modulator and the differen:-_ frequency after the 2nd. The lat balanced modulatcr feeds a two-stage IF amplifier. In the anode circuit oil the Ist stage is included the band-pass filter oystem, consist-ing of twc, sets of 3 crystals and a twin-gang variable condenser to cover the 20- and 15-meter bands. The second stage acis Card 1/2 as an additional RF amplifier and also converts the singi-e- An ~SB Transmitter phase voltage after the first filter into 'Iwo-phase voltage needed by the 2nd balanced modulator. The normal transmit- ter to which the shaping assembly is connected consists cf a master generator and power amplifier and works on 20.15 and 10 meter bands (Figure 2). It functions best when the anode circuit is tuned to the 2nd or 3rd harmonic. The anode circuits are interchangeable, a different one beirg used for each waveband. The output stage works as a Cla-'s C amplifier with an anode voltage of 1,000 -;-. When the shaping assembly is switched ir and the transmitter func- tions as an SSB transmitter, the output stage is ccnvertei from Class C into a Class AB1 by altering the negative bias from -70 to -45 v. The peak input power then comprises 180 watts. Details of boils, filters and chokes are given. The transmitter was linked to E. double quadrant, antenna aligned to the North, and to a rod antenna.

The filter is intended for i-f amplifier circuits where high adjacent- channel selectivity and small distortion within the pass band are essential. A number of high--Q similar circuitsinsure a very close to the square-; shaped frequency characteristic . An example of 5-section filter is considered in some detail.

SOVIC7--5,3-11 1 -~7/4C TITLE: An Ultralinear AmDlifier (Ul'tralineynyy usilitell) PERIODICAL: Radio, 11058, Nr 11, Pp 42-44 (USSR) ABSTRACT: The author discusses the resDective merits of the use of pentode and a triode in the output stage circuit of a h--,zh- fidelity 1-f amplifier. He explains how ultralinea-.- con- ditions preserve almost the same efficiency and output P0-.';e-_ as in a pentode circuit, while the internr-l resistcince I's nearly as g-reat as that characteristic of a triode circuit. The charaoteristics of an ultralineaz- ar.~cli.47ier can be sTill further improved by taking over into the cathode circuit that part of the primary winding which is led into the screen grid circuit (Pigure 4, upper circuit diagram). Typical cherall- teristics of amplifier circuits reviewed in the article are shown in Table 1. The sDecific requirements of the output transformer of ultralinear amplifiers are discussed, and the optimum values of the distribution coefficient of Soviet out- put valves, together -N-itb their typical electriQal conditions Card 112 when they are used in ultralinear amplifiers, are given in An Ultralinear A"Dlifier 0 Table 2.

On the basis of the latter generalized characteristics and resistance- and amplification diagrams are put up. These demonstrate theamplifying properties of the _ tkiode tramistdr '.. when small signals are used at low frequences. The introduction of m2 is explained as follows: the presence of an internal static feed-back in Lhe tri6de tranbist6r ' leads to the fact that the transfer Card 1A factors are different from zero in direct as well as in the
