TITLE: The negative feedback in transistor telephone amplifiers
PFMODlCLL: Telecomunicatii, no. 1, 1962, 17 - 24
TEXT: The article deals with the problem of negative feedback in transistor
telecommunication amplifiers. The authors consider the operation frequency of
the transistor to be higher than the maximum frequency in the amplifier band,
and treat only the configurations with comon emitters. The transistor may be
characterized by two small-signal parameters with a satisfactory accuracy. The
first parameter is the shortcircuited-current amplification (3, while the second
parameter is the slope S, which is a little smaller than the So slope of the
intrinsic transistor. In the first approximation, S may be considered to be
independent of the frequency. The input resistance is

is identical with h119 and is used in the entire article to simplify
the calculations. The authors then briefly describe the following simple cir-
cuits with negative feedback: (1) series-series feedback with resistor;
(2) parallel-parallel feedback with resistor; (3) combined series and parallel
feedback with resistor; and (4) series-parallel feedback with transformer.
These circuits are very simple but do not allow satisfactory stabilization. Very
good performance, however., can be obtained with single-stage amplifiers with
negative feedback by using two differential transformers, connected as shown in
Fig. 4. Although the two transformors and the transistor connected to the feed-
back loop introduce a slope of 6 db/Oct each, the stability of the amplifier
can easily be established. If the zransistor and the transformers have the same
maximum frequency, the critical gain is TH = 8. To stabilize the amplification
and the impedances, a value of 6 - 7 for T is sufficient in the majority of
cases. The authors refer to two sIngle-stage amplifier circuits with negative
feedback and with two differential transformers, giving the necessary formulas.

The negative feedback in transistor ..... D014/D105
In case of multistage amplifiers, the negative feedback with balanced resistive
bridges should be applied. The output bridge should guarantee a maximuiii load
power, and the input bridge a maximum noise. As an example, the authors describe
an experimental three-stage amplifier for a low-gain repeater to be used in a
24-channel 12 - 108 ke telephone system. The calculation modi of simple cir-
cuits with negative feedback and the balancing and attenuating conditions of
two eifferential transformers used in a single-stage ainplifier with negative
feedback are also presented. There are 10 figures and 11 references: 7 Soviet-

TITLE: The ST-3 system of transistorized carrier currents with three
channels
PERIODICAL: Telecomunicatii, no. 3, 1962, 100-107
TEXT: The article presents the transistorized three-channel ST-3
carrier current system to be used in open-wire telephone communications.
The ST-3 system was developed by the "I.A.Tc." which produces the R.M.
voice repeater and the single-channel ST-1 system in series and which also
developed the 24-channel ST-24 system for cable operation. The ST-3 system
can operate with two or four copper conductors by using a single modulation
and a suppressed-carrier single side-band. The introduction of three addi-
tional telegraph channels was also made possible. The ST-3 voice-frequency
band is 0.3 - 3.4 kc, the difference between the carrier frequencies 4 kc,
the call frequency 2,280 cps, the pilot frequencies 4 and 32 kc, the fre-
quenoy range of the system 4 - 32 kc, and the planned band for additional

national CCITT recommendations. However, the recommended pilot frequencies
of 16 and 110 kc and 31 and 110 kc could not be used due to their unusual
values. The system permits an attenuation of 5.5 N. A detailed description
of all parts of the system is given. There are 9 figures.

ABSTRACT: The results are described of investigations carried out
J_
in the Institute of Mechanical Engineering, Ac.Sc. USSR,
(Institut Ka-shinovedeniya AN SSSR) relating to the study
of iron-molybdenum and nickel-molybdenum alloys by means
of short-durationand long-duration hardness measurements.
The materials for the specimens were produced in a 50 kg
capacity induction furnaea. The Iron-base alloys
contained respectively 1r% Mo (alloy 204-) and 12% Mo
(alloy 212). The nickel-base alloys were alloyed
respectively with 7% Mo (alloY 307) and .2~5% Mo (alloy
325). As can be seen from T-,he diagram (Fig 1) the alloys
201+ and 307 remain in the entire temperature range single-
phase alloys and do not become transformed. The alloyE

quenching from the single-phase range they are prone to
dispersion hardening. The alloys 204 and 307 were
investigated after vacuum annealing at 9000C for two
hours followed by slow cooling in the furnace. Tne alloy
212 was investigated after quenching from 12000C in oil;
the alloy 325 was investigated after quenching in water
from 9000C. By means of hardness measurements, the
kinetics of ageing of the alloys 212 and 325 at various
temperatures were studied. The influence of ageing on
the microstructure of the alloy 212 can be followed from
the microphotos reproduced in Fig 2 (plate). The results
are described of the short-duration hardness measurements

ABSTRACT: The present work is a continuation of earlier investigations by the
authors, with the difference: that the factors investigated in this case were:
the modulus of normal elasticity, modulus-of.-rigidity, Poisson's ratio, logarith-
mic attenuation decrement, and Vickers hardness of hardened alloys of the Ti--Qx,-

these systems in the formation of the metastable phases oil, w and 0 of a pro-
sumably identical nature and structure, during hardening. An in the two previous
ivestigations, (S. G. Fedotov, 0. K. Belousov, Dokl. AN SSSR, 150, Is' 77, 1963;
155, 6, 1387, 1964), elastic properties of the alloy specimens hardened by quen-
Ching from 1000*C were measured by the dynamic method with the aid of an Elasto-
mat device. It was established that the different systems investigated display a
common pattern of variation in the specified parameters, which is associated with
the similarity of interaction between Ti and Cr. Fe. Mn. and Co. At first all the
alloy elements depress the elastic properties to a different degree, and there-
upon they cause an abrupt increase in these properties, which corresponds to the
formation of the w-phase. This maximum is again followed by a fall, due to the
fixation of the metastable 0--solid solutions. The general type and nature of vari-
ation in the elastic constants of alloys of the Ti-Cr, Ti-Mn, Ti-Fe, and Ti-Co
display much in common with
systems, which represent one type of interactiq
those of the alloys of the Ti_mo'1,7Ti-V v?ri-Nb- hnd other systems, which represent
-L.L !=Y
another type of interaction. Despite this seeming similarity, there also exist
definite differences in elastic properties, which the authors attribute to the
different nature of the interaction of Ti with elements of thdae two groups, since
2/4

L 2663-66
ACCESSION NR: AT5023095
the interaction of Ti with Gr, Ma, Fe, Co, and Ni is also characterized by the
formation of broad (Nn,.Fe, Co, Ni) or unlimited (Cr) ranges of P-solid solutions
and extremely limited ranges of a-solid solutions: in alloys of these nystemss
by contrast with alloys of the systems formed by Ti with Mo, V, and Kb, the
5-solid solution undergoes eutectoid decomposition, while the solubility of Cr and!
other elemeats of this group in o!-Ti also increases with the fall in temperature
to eutectoid temperature but, once a certain point is reached, it decreases again*
Hence, it is suggested that martensite transformation in alloys with eutectoid-
forming elements also takes place in two stages. The first stage of 0--a- tran
a
formation occurs in the same way as in alloys of the Ti-Mo, Ti-V, and Ti-Nb's;
tems. This is what they have in counon. The second stage of the transformation'
process takes place only in alloys with eutectoid-forming elements; this is what
differentiates the compared alloy groups. Here major significance is attached
to the temperature of eutectoid transformation. The higher this temperature is,
the greater, obviously, the extent to which the self-tempering of primary super-'
saturated a-solid solutions will occur and the more complete the recovery of
elastic properties will be. Conversely, a lower temperature of eutectoid trans-.
formation in the system complicates the process of the self-tempering of supers&-
turated a-solid solutions forming during the hardening.and'hence-contributes to th4

fixatioh of the more supersaturated at-solid solutions with lower elastic con-
stants. From this standpoint considered, the elastic properties of alloys of the
Ti-Cr system directly point to a lower eutectoid temperature than that of the
other systems investigated. 0jr1g. art. has: 3 tables.

by a decrease in the resistivity and an increase in the modulus of normal elasticity
and the shear modulus. With increasing supersaturation of 04, and 6 hard mixtures
there is an increase of electrical resistance and a decrease of E and G. In systems
with eutectic dissociation of' a hard mixture a self-tempering of supersaturated
hard mixtures occurs for which the degree of self-tempering Is higher with higher
eutectic temperature; this phenomenon is reflected in values of the elastic prop-

TITLE: The Separation of the Nuclear Isomers of Tellurium,
Mercury and Tin (Razdeleniye yadernykh izomerov tellura,
rtuti i olova)
PERIODICAL: Zhurnal Neorganicheskoy Khimii, 1958, Vol. 3, Nr 1,
PP. 181-183 (USSR)
ABSTRACT: After giving a review of the separation methods of the
nuclear isomers of tellurium (references 1,2) and after
their discussion the authors chose dimethvl-dinitrate of
tellurium as the initial compound for tlie separation of the
nuclear isomers of T127. It must be expected that the transi-
tion to an intermediate level will occur by means of an in-
ternal conversion and for this reason will be aGcompanied
by a disturbance of the chemical binding of tellurium in the
initial compound. Therefore a considerable portion of the
nuclei of Te127 will be present as most simple anor,~anic
forms in the ground state in the preparation dimethyl-
Card 114 dinitrate of tellurium. Te127 in its ground state was isolated

by means of the adsorption of these anorganic forms by
ferric hydroxide. The extraction with isopropylether from
9 n HC1 was intended for the removal of the an isotropic
carriers, that is to say, iron. From the decay curve of the
lowest isolated isomer (figure 1) follows, that only one
tellurium isotope was existent, which had a half life of
913 hours. This testified to the presence of only the lowest
isomer in the preparation. The yield of Te127 was determined
to 80%, if it was accumulated in crystals, and to 94%, if it
was accumulated in a solution. The latter value is in good
correspondence with the known fact, that the isomeric
transition in Te127 is converted to practically 100%. This
implies, that the initial molecule is destroyed by every
process of isomeric transition, which is accompanied by
an internal conversion. The yield is somewhat lower, if
accumulation takes place in crystals. The isolated radio-
active Te127 predominantly takes its four-valent form and
only 6 % of it take the six-valent one. This method possesses
several advantages in comparison to the ones known hitherto
Card 2/4 (reference 1). If mercury is irradiated with neutrons according

to the reactions (nq-) and (n, 2n), radioactive isotopes
are formed: Hg197' Hg1qq, Hg2o3 and Hg2o5. Because at least
six days elapsed until the separation was performed it can
be assumed, that in the sinthesized init*-al preparation -
mercury diethyl only Hg20 , Hg197m and H9197 were present.
From the in-?stigations of the Laboratory for Radiochemistry
of the 7 -,ersity Leningrad (reference 3-6) it results, that
the complete aliphatic mercury derivatives may undergo an
irreversible destruction of the chemical bondings on
isomeric transitions. The isolation of Hg197 in the ground
level was performed by means of adsorption on manganese
dioxide. The separation from the carrier can be achieved
by methods, which are based on the volatility of mercury
and its derivatives. The separation of the nuclear isomers
as such can be determined from a comparison of the curves
of decreasing activity of the mercury preparations
(figure 2). When tin is irrariated by thermal neutrons '117m
radioactive nuclei are formed: sn113 (yields InI13m, S.
and Sn119m by decay). From the three latter ones stable
isotopes are produced by an isomeric transmutation: sn117 and

will pass over into the water layer during the extraction.
For this reason the activity measurement was started after
lapse of from 10-12 half life periods of In113m (T - 105
minutes). The decay curve of Sn121 is represented by figure
The accumulation of SR121 with time was examined (figure 4)
for the pu:~pose of proving the genetic relation between
Sn121 in g:round state and Sn121m. The method described here
may be considered the most universal. It makes furthermore
possible t,3 isolate the nuclei in a low isomeric state
without carriers.

PERIODICAL: Zhurnal fizicheskoy khirnii, 1958, Vol 32, Nr lo,
pp 2392 - 2397 (USSR)
ABSTRACT: The true principle of the chemical chanjes in the isomer
transition was first explained by Segre, Halford, Seaborg,
Cooper (Khellford, Siborg, Kuper) (Refs 15,16), and
was experimentally proved as well (Ref 17). In the
present case the separation of the fenetically combined
isomers of the mercury Hg'95 and Hg 95m, as well as Hg197
and Hg197m 2 is investigated. The initial mixture
of the chemically pure metallic mercury was produced
in the uranium reactor. The preparation of the radio-
active diethyl mercury was obtained from the irradiated
mercury by way of H&C1 , using the Grignard (Grinlyar)
reagent. To separate tRe Hg197 the diethyl mercury
Card 1/3 was diluted with acetone (1:3), and a MrdnO 4 solution
The Separation of the Nuclear Isomers Hg195 and Hg197 SOV/'76-32-lo-23/39
as well as 2 drops of a 30%H202 solution were added.
The deposit was h1tered, washea and dried in vacuum.
The activity of the preparations obtained by the
decay of &Lqioactive diet'-,-.yl mercury mainly consists
of the H9 09 isotopes that have a lon- life, and
only to a cmall part of those of 11g197. The
separation process of the nuclear isomers was therefore
carried out under conditions for the
accumulation of H~~197 izomers (t max. 54,5 hours). The
experimental results after the separation of the nuclear
iso--ers si-owed that only s1lort-life activities of HG195
and Hg19~ isotopes are present, as viell as the un-
expected isomer H9195. The presence of Hg195 in the
preparatio,~s is explained by its formation from H&;-195m
(T= 40 hours~ in the irrad4~tior
I . of mercury in the
reactor accordir-- to the reaction Hg196(n,2n)Hg195m.
Chemical methods additionally proved that the activities
observed were to be explained by the mercury isotopes.

PERIODICALt Radiokhimiya, Y. 2, no- 5, ig6o, 603 - 613
TEXTs The purpose of this article was to develop a quantitative
method for separating radio-chemically pure astatine from irradiated lead,
bismuth and thorium, with fast protons, which would be easily reproduced
and would yield about 60 % astatine from the irradiated targets with a
yield tolerance of � 5 %. Development of such a method is hampered by the
insufficient knowledge of the chemical properties of At. In order to estab-
lish the quantitative method for At separation with good reproducibility of
the results the authors claim that it is necessary to investigate the be-
havior of the element at each stage of purification. This was accomplished
on radio-chemically pure At, separated out from thorium as an indioator.
The behavior of At was checked by the gamma-emissiong which, in turn, was

complete description is given of a method for the extraction of At. The
authors obtained an improved method$ using diluted HCl solutions (Figure 1).
Extraction of At increases in the presence of nitric acid. Small quantities
of HF which have been added to the dissolved thorium in nitric acid has no
effect at all on the extraction of At. The most convenient method for ex-
tracting At from an alkaline solution of sodium stannite after re-extraction
is said to be the co-precipitation of the element with metallic tellurium
from an acidified solution of stannite with HC1. Kurchatov, B. V.t Mekhe-
dov V. N. et al. (Ref. 1: ZhETF, 35, 1 (7), 1958) give a complete descrip-
tion of the method. Co-precipitation of At from HCl solutions with tellur-
ium helps not only to concentrate the At and eliminate the large quantities
of salts present in the solution, but also to conduct an effective purifi-
cation from Sb, Os, T1 and J. Experiments showed that the presence of small
quantitites of tellurium in the H2SO4 solution (-10 mg) considerably spoiled
the conditions of distillation of At. The recommended method developed by
the authors is described as follows& Based on data of the behavior of At
at each stage of purification it was suggested to dissolve 1 gr. of metallic

bismuth irradiated with 660 Mev energy protons on the internal beam of the
synchrocyclotron, in 5 ml of concentrated nitric acid, while heating it in
a flask with a reversible cooler; 40 ml of 8 M HC1, saturated with chlorine,
were added to the nitric acid solution. The extraction was carried out
with 60 ml of diisopropyl ether in an extractor equipped with a mechanical
mixer. The organic layer was twice washed with 15 ml of 6 M HC1. The At
was extracted from the ether with 40 ml of 0-1 M solution of sodium stannite
in 2 M NaOH. 10 - 15 mg cf sodium tellurite 2 - 3 mg of lanthane (LaC13)
and 1 - 2 mg of sodium chloroaurate were added to the alkaline solution.
The solution was separatEld from the residue by filtration through a glass
filter No. 4. The precipitation of the tellurium with the sodium stannite
was repeated twice. The alkaline filter was acidified with 20 ml of con-
centrated HC1, containing about 0.2 mg of Te to 1 ml.. The precipitation
of the Te from the acidic solution was carried out with intensive mixing.
After coagulation of the residue, 5 mg.of Te was added twice. The Te re-
sidue, containing At, wai3 separated from the solution by centrifuging,
washed with a 6M HCl and dissolved in a few drops of nitric acid. 20 ml
of 6 M HCl were added to the obtained solution, and the Te was precipitated
with stannous chloride. After coagulation of the precipitate, the preci-

pitation of the Te was repeated (5 mg). The formed residue was centrifuged,
washed with concentrated HC1 and dissolved in 5 ml of 8 M HC1 while p ssing
through a gaseous chlorine. The At was separated from the Te by extr:cting
it in to diisopropyl ether. The ether layer (about 6 ml) was washed twice
with 1.5 - 2 ml of 8 M HCI and the At was re-extracted with water (twice
with 5 ml each time). After extraction a solution was obtained of radio-
chemically pure At, about, 0.01 M according to HC1, containing traces of the
diluent. When extracting At formed from lead, the method is more compli-
cated, necessitating first the elimination of lead chloride, which preci-
pitates when HCI is added. to the nitric acid. The gamma-spectra of At were
studied on a scintillation spectrometer. Findings agree well with data of
Strominger D., Hollander, J. M., Seaborg G T. (Ref 16: Rev. Modern Phys.
309 2,o 7999 1958.) on gamma-emission of At~08, At2C� and At21O. When
measuring the At preparations formed from the lead, in addition to the
known gamma-lines, 3 lines were found (660 kev with T `5 hours, 165 kev
and 32 kev) whichiaccording to literature datalcannot be attributed to
isotopes of At. The total intensity of these lines is about 10 % of the
intensity of the entire specimen. The determination of the half-lives of

the various isotopes of At was carried out with sufficient accuracy only
for samples formed from thorium. It was impossible to produce radio-
chemically pure At frour lead. In checking the reproducibility of results
of the given method it was noted that comparitively large amounts of At
loss (u~ to 50 %) was coanected mostly with the incomplete extraction of
the At in the various stages of purification#,..However, it is pointed out
that these losses can be avoided by acidifyinig-the alkaline solution of
the stannite, containing At with HC1, to which small-quantities of Te have
been added. Here it is assumed that owing to the competition of adsorp-
tion of At on Te, the adsorption of the element by the walls of the glass
vessel is excluded. The favourable reproduction of results of the yields
makes this suggested met 'hod applicable for the determination of absolute
cross-sections of At formation in various nuclear reactions. There are

TEXT: The ''netics of isotope exchange was investigated and the reac-
tion rate constants of this exchange were determined, as well as the order of
reaction and energy of activation. The exchange kinetics were studied in order
to obtain a clearer understanding of the behavior of radioactive bismuth forms
in the exchange during the beta-decay processes of the natural bismuth isotoDeF,
The initial compounds were obtained according to methods described in Ref. 4

neniy surtmy i vismuts.( Synthetical methods in the field of metallorganic anti-
mony and bismuth compounds) Izd. AN SSSR, M.-L., 8, 1947). The solubility of
bismuthtriphenyl and bismuth triphenyldichloride in alcohol at various tempera-
tures was investigated in order to determine the conditions of separation of

the exchanging compounds. The isotope exchange in the given -vstem was studied
according to the method descrIbed by the author (Ref. 1: V. D. Nefedovj Tao
Syao-en, Zhurn. Pekinsk. univ., 4, 383s 1959). The experimental results showed
that the reaction of isol.-ope exchange in the given system is of the first order
A
with respect to each of the components. The reaction rate constants were calcu-
lated from the fornrala:
K -2.3 19 (1 - F)
(a + b) t
where F is the degree of exchange, a the concentration of Bi*(C2H.5 or
Bi(CI4 C5H5)3(in M), b - the concentratton of Bi(c6H5)3c'2 (in M), t )3the time
of exchange (in hours). The activation energy was found to be equal to 15.900
cal/mole. The investigated compounds were regarded as pseudoatoms and their
derivative (Ref. 5: R. Gar7.,Ov, L. Grimm. Organometalle. Sammlung chem. techn.
Vortraege, 29. Stuttgart, 1927). From this stand point one of the compounds par-
ticIpating in the exchange (BIOA)3) is regarded as a pseudoatom of mercury,
and the other (Bi(C6H5),C12) as its salt. Thus.,the investigated case of isotope;
exchange is considered to be a true solution of a pseudometal and its salt. An

assumption is made that the isotope exchange in the given system has an electro-
niQ nature, whereby the electrons shift according to the scheme:
1* 2e 4
Bi (C6 H5)3 Bi (C6H 5)3
4* 2+ 1
Bi (C 6H5)3 Bi(C6H5)3
I ensures the isotope exchange of Bi amongst the studied chemical forms. The
low value of the activation energy is also thought to signify the presence of an
electronic exchange. The use of doubly-labelled compounds can serve to solve
the nature of the exchange meohanism In the given system and others similar to it.
A comparison of the kinetic characteristics of the isotope exchange in the sys-
tems Sb(c6F15)3 - Sb(C6H C12 - alcohol and Bi(C H5) - Bi.(C6H5) C12 - alcohol
led to the conclusion 22 the isotope exchange in tAese two systems have similar
rates of reaction. The cause of the similarity in the kinetics of exchange in
the two systems is thought to be due to similar values of the bond energies of
V H and that of the 6s-electrons of the
the 5s-electrons in 'he pseudoatom Sb(C6 5)3
