In-ta. 1958, PP 33-311, 91-94 ABSTRACT: Corrosion (C) of Pb-wrappings of underground cables can take place under the action of erratic currents as well as due to electrochemical or chem- Ical C. One of these causes can be established on the basis of detection of Pb02 In the C products. For this purpose a method has been developed for the determination of PbO 2 which is based on the oxidation action of' the latter on HCI (gas) with the subsequent detection of the separated C12 by means of moist lodine-starch paper. The pro sed method is dis- tinguished by a sufficient sensitivity of 1.5 - 10-rg. The presence of nitrates and nitrites distorts the results. For their elimination the prelimInary washing of the sample by hot water is recommended. V. Pritula. card -I/1- SOLODOVNIKOV, P.P.

The traJn consists of track motor car carrying a crane on which the welding machine is suspended, as well as three cars carrying equipment for remote control of the welding machine, a diesel generator, and portable accessories. R-50 type continuous rails of various length (250-800 m) are thus welded together from rail segments of Card l/A UDC: 621,791:625,143 -i-. __ 4L'__'7C-66__ __ - - ACC NR- AP6021008 a fixed length (25 in). 7le welding process conslatod*of kserfd6of operatfons, each handled bya separate team of workers.

After this, the welding train approaches the prepared pair of contacting rails and the machine proceeds with their butt-welding and the attendant trimming of the hot welds by, means of pneumatic chipping chisels. After the welding and trimming are completed, the ti4in advances toward the next pair of contacting rails, which by then Is'prepared for welding, while another team of workers is carrying out the normalizing of the preceding pair of rails at th@ underside of the contacting surfaces.

On-track welding of this kind Is definitely more economical thary stationary welding, since it eliminates the need to build stationary rail- welding enterprises costing 400, 000 to 800,000 rubles each, and thus It also eliminates the need for a special train (consisting of 78 two-axle flatcars) for carrying 800-meter continuous rails from the welding site to the rail-laying site, and moreover then a high and stable quality of welding of the rall butt joints is assured. An'average welding train of this kind can.. process 70 km of track in a single year. Orig. art. has: 2 figures and 2 tables.

T-ie tal results are given in the table. As it can be seen the exchange rates in the dark and on light exposure are in accordance within error limits. This indicates that the higher concentration of iodine atoms in the volume due to irradiation does not affect the rate of the isotopic exch.ange.

This suggests that in the volume no radical chain reaction takes place as it is the case in solutions where the disappearance of alkyl radicals in the oxygen reduces the rate of the isotopic exchange. The dependence of the reaction rate on the pressure of the components is shown in figure 2. Accordingly, the reaction rate depends up to 0.2@ nm linearly on the pressure of iodine. At higher pressure it remains practically constant. This is apparently in connection with the fact that the reaction is proceeding on the surface in this case. At a pressure over 0.25masaturation of the sur- face occurs whereby an increase in piessure does not cause any considerable change in the reaction rate.

Seriya fizicheskaya, 1959, Vol 23j Ur 10, pp 1265 - 1264 (USSR) ABSTRACT: In earlier papers (Refs 1-3) it has already been shown that in highly diluted dibenzene chrome solutions the interaction be- tween the unpaired ele,@tron and the protons of the benzene rings, which are in connection with the metal (chrome-) atom, manifest themselves by a disTinct hyperfine structure of the spectrum of parama.--netic electron resonance. It has already been shown that the introduction of a substituent into the benzere rinG influen,@es neither the g-factor of the compound nor the amount of the hyperfine splitting (3-@_+0-5 Go). It was further found that the dissolving temperature, the nature of the solvent or that of the substituent introduced into the benzene ring the width of the hyperfine structure component'.

Further investigations zon,@erning hyperfine splitting were carried out with the cation of dibenzene chrome with cy--lo- hexyl substituents in both rings. It was found that at low temperatures of the solution of this compound an additional triplet splitting ('1+0.5 Gs) of each hyperfine structure com- ponent occurs. It is cauged by the interaction of the unpaired electron with two protons of a cyclohexyl substituent. kn in- vestigation of the influence exerted by various factors on the width of the hyperfine strvcture component gave the fol-- lowing result: A considerable dilution of the solution with a reduction of temperature leads to a monotonic improvement of the spectral resolving pow-,r, i.e. the width of the hyperfine structure component der@rsases.

The authors in- vestigated the e.p.r.-spectra of some benzene derivatives. The ion radigalaiwere produced by the reaction of the compounds dissolved in 112-dimethoxyethane with metallic potassium. Low temperatures were applied for very unutable ions (down to -700)- The e.p.r.-spectra of the following benzene derivatives were -diacuesed: cumenel(Fig 1), cyclohexyl benzeneJ tert. isobutyl benzene, toru-ene,4ethyl benzone.lThe spectrum consisted of 5 lines with ype@fine structure and binomial intensity dis- Card 1/5 tribution.

In the toluene anion (Fig 2) each of the 5 lines is separated into 8 components due to the interaction between the unpaired electron with 3 a-protonu and the proton in p-position. In the investigation of the spectra of o-, m-, and p-xylene more detailed results were obtained than had been given in reference4. The measurement results and the calculated spin densities of the unpaired electron are summurizel in table 1. To investi- gate the transmission of an electron along the chain of the conjugate or naturated bonds the e.p.r.-spectra of the anions of stilbene, azoxybenzene, and dibenzyl were investigated (Fig 3). In stilbene the possibility of a delocalization of the electron along the benzene ring and along the chain of the conjugate double bonds was proved. The spectrum of azoxybenzene H H 0 showed that the replacement of the bridge -CuC- by -K-N- does not reduce the mobility of the electron over the entire molecule.

They then describe their own investigations of the formation of the kR of benzene and toluene. The following solvents were used: 1,2-dimethoxyethane (DRE), 1,2-methoxy-ethoxy-ethane (KEE), 1,2-diethoxyethane (DEE), tetrahydro- furane (THF), and 1,3-dioxane (DO). The AR were detected by means of electron paramagnetic resonance. The frozen solvent with the aromatic com- pound was placed in an evacuated ampoule, on the walls of which potassium Card 1/3 kr" The Influence of Metal and Solvent Upon the B102016011331031121013 Formation of Aromatic Anion Radicals as Initiators B004/BO56 82276 of Polymerization had precipitated. Experiments carried out with benzene (0-4 mole in 1 1 of solution at -30 0C) with an addition of K and DME produced an AR concen- tration that was 4 to 5 times higher than with DEE. With Na and DEE the AR concentration was lower by at least 2 orders of magnitude. Parallel experiments carried out with Li and Na in DEE at -70 0C gave a considerably higher AR concentration for Li. Experiments with toluene supplied the data given in Table 1. The relative concentration of AR was determined, the AR concentration in DME being set equal to 100. The experimental results led to the following conclusionss 1) Benzene forms AR with Li, Na, and K. Potassium-anion radicals formed in all solvents used; 2) substitution of the methyl group of ether by the ethyl group decreased the stability of AR as a result of steric hindrance. Stability decreases in the following ordert DME, MEE, DEE. 3) The sodium compound of dromatic hydrocarbon1does not form so easily as the and Li-compounds. - The initiation of the polymerization of styrene7w-aa investigated by means of benzene potassium in DME, MEE, and DEE.

The polymer molecules were converted into anions by interacting of aromatic hydrocarbons with metallic calcium dissolved in 1,2-dimethoxyethane. Spectra of e.p.r. were taken at room temperature, the concentration of the paramagnetic particles being about 10-4 mole. For the different polymeric anions examined, lines with a diffuse hyperfine structure were obtained alongside with the spectra containing resolved hyperfine structure. A direct method of the evaluation of degree of delocalization of unpaired electron was used for the interpretation of the experimental results.

EPR spectra of the anions C6115 (CI12) n - C6115, where n=1 and 2, correspond to relocation of the unpaired electron on two plienyl rings, while where n > 2 they correspond to localization of the unpaired electron in one phenyl ring. The equilibrium between the anions and the original hydrocarbons was invefitigated for benzene, toluene and p-xylene. S.

The con- ference took place in Rio de Janeiro. 28 delegates and two observers from 8 countries participated in it: Brazil, Bri- tish-Viest-Indial Mexico, India, Francev Chile, USA and USSR. The conference was held under the title "Capital and Foreign Trade in the Theory of the Economic Development as Illustrat- ed by the Example of the Countries of Latin America". Alto- dether 15 reports were given. Representatives of Slavic countries did not participate. At the end the Soviet observer remarked on the differences in the opinions of the represen- Card 112 tatives of underdeveloped countries on one side and the USA International Conference of Economists irprazil 30-2-16/49 on the other side.
