ABSTRACT: A device and a suitable method for simultaneous microscopic and
electrochemical investigation of ~vtreas-~c:6ri*osion dracking''1w-*6-cY-';*
eases were developed. The device includes a te.naile.-testing
machine with a Yisual and measuring recording system. Axial
tensile loads up to 250 kg can be applied; the total e-'edtrode
potential.of the metal, and the potentials inAhe result:Lng
cracks, are automatically recorded, and visual observation of
the propagation kinetics-of cracks
is possible. The~tests are
.
carried out in a corroding medium which is constantly renewed..
The loading (stretching) takes place on the tensile-testing
machine (Pig-1) by means of a metal spring, and is adjusted-by
a set wheel. Visual observation-of the sample (of cracks) is
done by a microscope of type MIS-11. The tensile-testing,nia-
chine was adjusted by a dynamometer of type DS-1. Immediately

sample by a glass tube. The changes in the electrochemical Do-
tential in the cracks were measured by means of appropriate
capillaries, an electron amplifier (Fig 2, Diagram), and:a loop
oscillograph of type MPO-2. The corrosion of alloy MA 2~was-
tested in a solution of Na Cro (20 g/1) and Nacl (35 g1l). The
2 4
oscillogram (Fig 3) of the potential changes on the sample sur-
face on stretching shows that, by the destruction of the oxide
film, an intense formation of anode segments occurs producing
a maximum in the oscillogram. New microc~ells (oxide-film loores)
formed at the same time effect a retardation of anodic poilar,iza-
.tion on the whole metal surfacei The appearance of cracks
causes the formation of a steadily incre6sing.anodic segment.
From a visual point of viewp the propagation of.cracks cart be
divided into 3 periods: (1) The incubation period (from the be-
ginning of loading until the formation of cracks); (2)'the
period of uniform propagation of cracks (formation of hydrogen
bubbles), and (3) the period of accelerated crack development
(apparently of purely mechanical character). An increase in'

the reduction of anodic polarizability. Concerning impulse~polarization an
equation is derived for the potential drop 6E. after switching off of the
polarization current io. Fig. 2 shows that the discharge curve can be reproduced
by the equation for the discharge of Ia capacitor, which ie,shunted by means of
a resistor. Fig- 3 shows the change of anodic polarizabilit; in the course of
y
development of the corrosion crack. By means of a microscope a.vigorous
separation of hydrogen was observed at the deepest point of the*crack, whereas
on the sides of the crack no hydrogen was formed. On the.basis of experim 191ntal
data, the authors arrive at the conclusion that the rapid development of'thi?
corrosion crack was caused by the sudden intensive decrease of anodic.poliriza-
tion (up to six orders of magnitude) in the zone of crack formation. Here,~'aot
the entire crack, but a limited region in its deepest point served as anode. The
authors refer to papers by A. V. RyOchenkov et al. (Refs- 3,,4) and P. A-~

ABSTRACTI The variation of the membrane potential during passage of electric enirrent
through an electrodialyz r wit an ion exchange membrane was studied on cation-ex-,

change membranes (brandAK, ase'd on KU-2) and anion-exchange membranes
based on RDE-10P). Curves re~a.:
i re senting the change of the raiibrans potential with time
-were plotted in order to determine-the kinetic*s and degree of concentration polarizar
tion of the membranes. Under conditions where a limiting current: flown through the
membranes a substantial part of the current compriseis the migrati6 componentq so that
on
the aegaerat of the limiting current on the polarization curve has:& slope which in-
creases with increasing transference n-dMber of the i6n in the free solution and vith
the absolute value of the limiting current. The limiting current densities were do-
termined, for DIA-0 and 19-4 membranes in solutions of potassium chloride in the.
0-005-0-1 N concentration range. A linear character of the dependence of ilim on:co
can be observed in dilute solutions.;i As the concentratic-.. ofthe electrolyte.-

TEXT: The fixtures of the BR-5 air-fractionating apparatus, which is in
operation at Chelyabinsk and Krivoy Rog, are regulated by six types of push7but-
ton-controlled 314M (EIK) servo-mechanisms. The-latter consist of an electric
motor, a reducing gear, a coupling between reducer shaft and armature shaft;
further, of additional fixtures such as position indicator and limit switches.
The remote-controlled fixtures differ from earlier hand-conirolled types only by
a spindle which has been modified for linkage with the servo-mechanism shaft. The
electric motors of the servo-mechanisms are push-button-controlled from a desk
stand using reversing switches. Thermal relays prevent overloads. There are 13,

A,BSTRACTt First a short report is given on previous papers dealing with
the same subject. Several patents recommended the application
of cupric oxide which has to be applied to different carrier
materials. The following problems remained unsettled:What
is the phase composition of the copper contacts ? 'What happens
to the catalyst during the reaction and which oxide is cata-
lytically active ? For settling these problems 3 series of
experiments were carried out, the following catalysts being
usedz 1) CuO; 2) Cu~O; 3) metallic copper applied to pumice
stone. The phase composition of the catalysts before and
after the experiment was roentgenographically investigated.
The roentgenographs were taken by a Debye (Debaye)-chamber
of a diameter of 57,3 mm with the K,,-radlation of iron.
The catalysts were tested for 40 minutes in a dynamic de-

leads to a reduction of the oupric oxide to protoxide and
also to metal. Originally existing ouprous oxide was reduced
to copper under these conditions. Whe swebpinz of the copper
by an air-propylene-mixture at 300 C leads to its partial
oxidation to Cu 20'. The additional electronographic investi-
gation of these catalvats showed that after-its application
in a propylene-air-mixture the surface of all investigated
samples was covered with'a layer of cuprous oxide. Thus~ the
cupric oxide in the Iresence of a propyle'ne-air-mixturi is
reduced to the system Cu 0 + Cu and metallic copper is oxi-
dized to cuprous oxide. iropylene in the presence of cuprous
oxide is oxidized to acrolein and in the gases developing
in this process almost no oxygen is contained. Consequently
the catalyst during the reduction has an effect in a re-

ABSTRACT: In the present paper the properties of Us cuprons oxide catalyst
which was used in the catalytic 6xidationi of propylene in, icrolein
were investigated. Further its activitrwas compared with.-6ther
oxidizing contacts. In order to clarify the part"ac*taldebide ilays
in the oxidation of propylene the method of the marked atois was
used. The oxidation of the propylene mixture with oxygent 'nk with
acetaldshyde marked with radioactive carbon (I t 2 t 0.5) or,
cuprous oxide at 350P permitted the definition.of the genetic
compounds of t1wee reaction produots. The results of a typical
experiment are illustrated in figure 1,;As can be seen, tbo cirbon
dioxide is mainly not formed from acet4dehyde brat independently
via other intermediates. The data devised according to the kinetic
method of M. B. Neymw (Ref 5) are given in figure 2. By Vis use of

same time and independently of one another several:parallel
reactions take place, in which connection unstable intermediates of
the peroxide type are formed. Purther some experizetts werecarried
out in which the effect of the contact time upon the oxidatimi
process of propylene was investigated (Fig 3). The acrolein'y%eld
first increases on prolonged contact -time but later remains constant
whereas the yield of carbon dioxide continuously increases.~Daring
the oxidation of propylene on the copper catalyst the acrolein is
not completely destroyed. Probably at the same time and
independently two reactions take place: The formation of acrolein
and its oxidation up to the carbon dioxide; P The rate ratio of this
process is*deterained by the composition of the~gas mixture* In
order to clarify the dependence of the acrolein yield on the
concentration of the catalyst on the carrier, several samples of
the catalyst on pumice and carborundum were investigated (Figs 4-7).
Tfie investigation indicated that the selectivity of the process can
be obtained by shortening of the contact time, byAncrease ofthe
linear velocity of current as well as by a decrease of the copper
concentration on the carrier which determines -the course of them
process in the kinetic range. Under certain conditions the length

ABSTRACT: The phase transformations were continu ously controlled by.
means of radiographic recordings in the course of the reac-
tion itself. These picturea were takon by means of a special-
ly constructed.cameral the constructional principles of which
are described in form of a schematical drawing. The tempera-

ture of the catalyst was recorded by M04Lns of

and was kept constant with an accuracy of + 1 . The Xrray
beam dispersed by the sample was recorded in a plane film.
For the catalyst investigated, good resolution and a PatiB-
factory intensity of reflections was attained by using,:an
X-ray tube of the type BSV-4-Cu without filter. Like in a~

copper were investigated. The copperoxide was produced by,
the oxidation of Cu and Cu 20 by atmospheric oxygen. The
cuprous oxide was produced according to a method developed
by D. N. Finkel'steyn (Ref 2). All experiments were carxied
out at atmospheric pressure in a gas mixture of the following
composition: propylene 15~6, oxygen 15%, and nitrogen M~-
The results obtained by identificaiion:of the X-ray pictures
of the catalysts are shown by two diagrams..In the oxidation
of propylene over copper oxide at 310 the C:atalyst Was reduc-
ed, and after operation of 210 minutes cuprous oxidel:wa3

(343 and 370 ) increases the rate of reduction,considerably.
Besides the formation of cuprous oxidst a motallic phaino could
in both cases be observed, which occurs all the more~rapidly
the higher the experimental temperature. It, however, the
propylene is oxidized for 135 Minutes Over CuO (370OL only

on a copper oxide catalyst a highly reaptive.compound is
obtained, viz. acrolein, is obtained, which pay -enter
into an oxidation- and polymerization reaction in thevolume
phase and also on the surface of the catalyst at temperatures
of 400-450 . It was therefore of interest to investigate the
influence exercised by acrolein upon the phase conversions
of the copper oxide. The passing of a mixture of aorolein
vapors (0-5%) with nitrogen leads to the reduction of cop-
per oxide to Cu 0 + Cu. The addition of oxygen to the gaa

mixture sharply slows down the reduction of the catalyst,
and a polymer film is formed. B* treating a copper film by
a mixture of acrolein (Q-5-5-07-9 oxygen (15~),.and nitro-
gen at 4000 for 2-3 hours the copper is oxidized to copper
oxide, and at the same time a polymer film is produced on
the surface of the catalyst. There are 3 figures and 2

TEXT: The authors attempted to determine the rules governing the
oxidation of propylene to acrolein and CO. on a copper catalyst. The
experiments were made in a continuous apparatus under atmospheric
pressure. Temperature was kept constant by means of a photoelectric
thermor-agulator in which a portable TTTT(PP) -potentiometer was used. The
gases ware analyzed for CO and CO on the b--sis of their infrared

absorption spectra and by means of PKTr 5 (GTP-5) gas analyzers. CuO
produced by impregnating sillite or pumice with Cu(NO 3)2 and.by heating
to 6oo - 700 0C served as catalyst. Experimental data are given in

TEXT: In this paper the authors studied ithe oxidation Of Dropylene:on

to acrolein on CU 20 proceeds according toatparalle1euccessive scheme..A
step-by-step scheme is presumed; (I)! On the basis of the.change of the
work function of the electron during adsorption of reaction components on

It was shown that the oxidation rate of propylene to acrolein and carbm
dioxide is proportional to the oxygen concentration in the gas phase(Ref,

the activation energyand k' (factor of the e4tponential functions for the
reactions of the formation Of acrolein and C02 ) depend on the work func-.
tion. For greater values of the work function, the activation energy of
the formation of acrolein is reduced and that of CO increased. From.the-
2
dependence of the isotopic exchange on the work function JP., the rate of
which increases for smaller values of V, the controlling effect of the
work function on the surface concentration of 0 2 may be inferred. The
selectivity of the acrolein synthesis is increased through the introduc-
2- in
tion of acceptor additions (SO 4 , Cl CuO and reduced by that of
donors (Cr, Fe, Li). The oxidation of ethylene to ethylene o#de is a
typical process proceeding according to a parallel schemel(Ref. 10). The
following signs of the charges of the components of the studied reaction
were ascertained: ethylene and ethylene oxide are donors, oxygen and C02
are acceptorsiPis only slightly reduced by water. The step-by-step
oxidation scheme proposed in Ref- 4 could be explained on the basis of

the signs of chargesdetermined: (II). Data with regard to the kinetics of
the oxidation process, available from publications and often paradox,.can
probably be traced back to the dependence of the partial surface concentra-
tions of 0 and C H on the change of the work function., The activation
2 2 4
energy of the oxidation of ethylene to ethylene oxide ought to change only
little in the modification of silver, since the surface concentration.of ,
donor molecules is increased through an' increase of 'f,,. These in turn -1~w-el
the change offunder the effect of metalloid additions. It was shown that
an increase of the work function reducei the activity of silver and raises
the selectivity of the process. Conclusively, the studies showed the'
following: There is an interrelation between the work function of the:
electron and the activity of the catalysts and the selectivity of the
oxidation processes of unsaturated hydrocarbons. The oxidation of hydro.-
carbons proceeds over a number of parallel and successive stages and,
according to the reaction mechanism, is differentially cont rolled by the
work function of the electron. The inhibition of a total oxidation with
an increase of the work function is characteristic of the reactions stu(bed.

For the quantity mentioned in the third line it applies that n - Q/q with q
= 35,5 h1eV = 69t5 me' All values of n are very near whole numbers, with the
exception of some cases in which decay furnishes~only stable particles (e.g.
neutron, no). Thus, the energy liberated on the occasion of unstable particles
is a multiple of 35,5 MeV. A drawing shows the experimentally observable scheme
of the energy levels of hyperons.
If the statements made here are correct, and if new unstable particles exist,
they must be found among those mass numbers M which satisfy thexelation
M - (m. p+M1 njq (in the ease of particles which are heavier than a proton),
or M - n in n,q (for'mesons which are heavier than a pion). In these fo,rmulae
n and n1 are whole numbers.
It is interesting to note that the w2mb*r of electron masses contained in q
is very near the value 1/2a - 68,5-

on Nucleons (Priblizhennyye dispersionnyye sootnosheniya dlya

PERIODICAL: Doklady All SSSR, 1957, Vol- 117, Nr 5, PP. 785 - 787 (USSE)
ABSTHACTt Here the scattering of nucleons on nucleons is discussed in the
absence of antinucleons, in which case the authors startfrom a
dispersion relation determined in the usual way, which is given
here. The amplitudes of the scattering of a nucleon on a nucleon
are here linearly expressed by the amplitudes of the scattering
of an antinucleon on a nucleon with positive energy. By this means
the abovementioned dispersion relation links the amplitude of the
nucleon-nucleon scattering and of the antinual6on scattering.
This dispersion relation is then given in the approximation con-
sidered here, This approximation is satisfactory in that energy
range, where the amount of the integral is essentially deter-
mined by the behaviour of the funotion within the integral, aign
of the approximation relation. In the case of the nucleon-nuale6n
scattering the identity of the particles must be taken into con-
sideration. Besides, it is not sufficient to consider the ampli-
tude f (0) of the scattering through a certain angle ~Q , biit~

scattering angle in the center of mass system. Subsequently a
dispersion relation is deduced and given, taking into considers-
tion a further possible approximation. Th e experimental verifi-
cation of just this relation is of great experimental interes't.
The experimental data available at present on the total section
a(k) and on the angular distribution permit to compute the inte-
gral from the total cross section, and the value of D(k) obtained
in this way can then be compared with the value measured~experi-
mentally. This verificytion will solve the problem of the limits
of applicability of the last mentioned dispersion relation. In
the range_of very small energy (up to 6 LieV), where the scattering
is satisfictorily described by a S-wave, the expansion k otg 6 a
- -(l/a) + (1/2) rk2 may be used to verify the last mentioned dis-
persion relation. The degree of accordance is given here.

ABSTRACT: Prom a modern point of view, a nucleon is a "nucleus"
which is surrounded by a cloud of virtual mesons. The
distributions of the electric charges and of the magnetic
moment of the nucleons rere investigated thoroughly
in Hofstadter's (Khof3htadter) experimentq on the scatter'i-ng
of electrons on protons and neutrons. It is therefore
interesting, to investigate the influence of the form
factor on processes like bremsstrahlung or pair production
on nucleons. The aulhors calculated these processes for
the special case of protons in the lowest approximation
of the perturbation theory (in the third order with respect
to e). The graphs taken into account are shown in a figure.
Also the "meson fur" will give an additional contribution
Card 1/3 to the cross section of these processes. But taking

The Bremsstrahlung and the Pair Production on Protons SOV1156-35-1-58/55
in Consideration of the Form Factor
account of this contribution is rather complicated and
therefore only some comments on it are given in this paper.
The exact formulae are rather complicated and -therefore are,
not given in this paper. When the proton mass tends to
infinity, these formulae are changed to the correspnnding
formulae of Bethe (Bete)-Heitler (Gaytler) for the brems-
strahlung and pair production. Deviations from these for-
mulae will be observed only in t~.e region of large scattering
angles or in the region of e.xtremely high energies of the
incident electron (1~500 MeV). This leads to the following'
conclusion: A difference between the Bethe (Bete)-Heitler
(Gaytler) formula will be an argument in favor of the in-
fluence of the recoil and of the form factor on the cross
section of the investigated process, and also in favor
of the possible existence of an additional cont:ribution
of the "meson fur" of the nucleon on the cross section.
In order to illustrate these -ionsiderations, numerical
results are given in a table. The above mentioned differenct,
has noticeable values (,j 15 0146) even for relatively small
Card 2/3 angles (300) and this fact is an argument in favor of a

dispersion relations are suited at least for'.the estimation
of the conti7ibut3.on of the single-pion state to the proc .eases

important extension of the energy range in the examination.'
of quantum electrodynamics at small distances may be attained.
The quantum electrodynamics for bremsstrahlung at an energy

relations, form factors depending rigorously on a varia~blo
may be introduced into the process of bremsstrahlung ands
pair formation. These form factors have lalready been deduced
by R. Hofstadter for the negative values of the argument
