determine the relationship between the properties and composition
of'systems in which chemical processes take place, In Chapter I,
derivations of generalized Stepanov equations (ba;3ed on the law
of mass action) were used to establish some new r.~lationships in
studying the metrics of diagrams of systems of dissociated com-
ponents, with special attention to the solvent as a third com-
ponent, which permitted the application of chemical diagram metrics
to condensed systems and, to some degree, the a~pllcatlon of
limited ideal laws (e.g. the law of mass action to liquid systems.
Also, the metrics of crystallization isotherms under conditions of
an ice field in the case of neutralization and camplex-forming
reactions, and solubility isotherms of three-component metallic
systems are briefly reviewed. The author thanks F. M. Cherkashina

TEXT: The object of the present investigation was to determ1ne'
the causes of instability of the thermoelectric and mechanical
properties of W-Re alloy in relation to the conditions and duration
of heat-treatment. Wire specinions, 0.5 and 0.34 mm in diameter,.
containing 5, 10, 15 and 20 vrt.t.(~. Re Call.oys ~>9(VR)-59 VR-10, VR-15

(20 - 700 h at 14oo , 2 000 OC) was conducted in vacuum, in argoy% or
in hydrogen. All the investignteci compositions were in the single.'
Ji-phase range. The Re content of the alloys was checked by chemic&1
analysis before and after heat treatment. The experimental work
comprised measurements of thermo-e.m.f , X-ray diffraction analysis
and examination of t 'he microstructuro!j of longitudinal and trans-.
verse cross-sections of the specimens. "The thermo-e.m..f. Incre"ed

this statement does not tally with the contents of a table in which
the results of measurements of thermo-e.m.f. are reproduced, there
being no clear correlation between the values of the'thermo-a.m.f.
and the conditions of heat treatment-V The thermocouple VR-15/20
(-with a high Re content) proved more stable in hydrogen at 1 800
2 000 0C thaziCthe thermocouple VR-5/20 with a lower Re content. Thp
Re concentration increased with increasing annealing time, the
relative increase being higher for electrodes with lower Re content&
The relative change In the Re content waa lower in vacuum than in
argon or hydrogen. The degree of recrystallization of thermo-
electrodes increased with increasing temperature and time of the
t-reatment and dependend on the Re content. A slight lonjitudinal
s'plitting of the electrodes was caused by texture, uhich persisted
even after prolonged annealing. Phase analysis shoi-iod that all the
thermoelectrodes studied constituted solid solutions whose lattice
constants depended en -the composition of the alloy. In som .e

specimens, the a- and phases were also observed. The formation
of the o--phase was attr&U-ted to a decrease in the tungsten content
in the P-phase, caused by a reaction between tungsten and impurities
(oxygen, nitrogen, carbon) in the ambient atmosphere. The thermo-
Clectrode VR-20. treated in vacuum for 700 h, contained the
O-phase in equilibrium with the \/-phase with a lattice! constant
a = 9.63 1EX, which indicated th f1t _the cr-phaso of the system W-Re
existed at te-iiDeratures above 1 400 OC. Prolonged "holding at
11000C brought about decomposition of the cr-phase and attainment
of the P +-y equilibrium. 'Finip-steii carbide formed during,

annealing in vacuum above 1 300 C due to the preseace of 6il
vapours, was present in addition to the P-phase in thermoelectrodes
operating in vacuum. When the specimens were vacuum-annealed for
20 h at 2 000 0C in a furnace with graphite heating elements, W 2C
or the cr-phase (in specimens with a Re content of 2-390 of the
W-Re system were precipitated from the P-phase. Alumina sheaths
did not offer sufficient protection against the effect of'carbon
at 1 800 - 2 000 OC. The formation of W C and the o~-phase at

1 800 OC could be prevented by 11sing0beryllia sheaths which,
however, were not eff ective at 2 ooo C. Tile presence of the

;.ABSTRACT: The existence of compounds of the rare-earth elements with metals,
composition and the type of crystalline structure were investigated, with particu-
lar attention to the similarities and differences between the various rare-earth
elements,as well as between these elements and their neighbo~-s in the periodic
table. The systems of La, Ce, Pr, Nd, Dy, Er, Gd, Tu and Y with magnesium were
investigated first. It was found that there are no c?mplete analogies in these
systems, but that the system Y/Mg is closer to Er/Mg than to the La/Ce system. In
the systems of rare-earth elements with zinc, aluminum and germanium, new compounds
were found, the structural parameters of which are given. It is interesting that
ths symm Y/Al differs from the system ErIAI and is similar to the system with

ted and their parameters are given. In the La/Fe system no compounds are formed.
A weakening tendency to form compounds with a decreasing order number of rare-earth
elements is also found in many systems with-manganese. Finally, the ternary sys-
tems cerium-transition metal (or copper)-aluminum and cerium.-aluminum-silicon were
investigated and their lattice constants are given. Orig.art.has; no graphics,

TEXT: The authors estimated the scattering of sound frcm an internal wave
between two liquids whose refractive indices differed relatively little
from one another. The measuring apparatus consisted of a plexiglas tank,
a vibrator for exciting the internal standing and running waves with 4 to
20-cm wavelengths and 0.3 to 4-cm amplitudes at the boundaries between two
liquids, sound emitter and sound receiver, transmitting and receiving
electrical channels connected with the counter. The shape and the
statistical propertieu of the internal wave were studiej by an electrical
resistance pickup. Fig. 3 shows the curves for the correlation
coefficients of the inhomogeneities Superimposed on the perio0ic wave in
the direction of the propagation (Curve 1) and in the direction vertical
to it (Curve 2). The fluctuations in the boundary displacement were
,ji/10 of the mean wave amplitude. The modulation of the scattered wave

TITLE; The deformation of a sound beam by an internal wave on the
interface of two liquids
PERIODICAL. Akusticheskiy zhurnal, v. 9, no. 1, 1963, 112 - 113
TEXT: The field of a sound beam scattered from a quasiperiodic interface
of two immissible liquids (water and turpentine) was studied in an
experimental apparatus. The angle of incidence was 300, and the periodicity
was excited mechanically. The aim of the study was to demonstrate that it
is possible to simulate the influence of internal waves on the sound field.
The emitter was installed in turpentine and sent pulses (500 kc/s) of
10 - 1501Lseo duration) to the interface. The sound field was measured with
a receiver which was identical with the emitter. Resultsi The beam width
varies periodically. The distortion of long waves is greater than that of
short waves. The pressure maximum in the reflectdd beam is somewhat
smaller if the interface is periodical than if the beam is reflected from a
plane interface. If the beam impinges on a convex part of the interface it
is broadened to --10 % of the width compared with that reflected from a

TITLE: Wideband amplifier with a semiconductor modulator-demodulator channel I
SOURCE: Priborostroyeniye, no. 6, 1966, 13-16
TOPIC TAGS: wideband transmission, dc amplifier, junction diode
ABSTRACT: The authors discuss the development of an amplifier system which can be us-,
ed as a control element for guided models. The requirements of high grain, and stable
wideband amplification of control signals are met through the use of semiconductor ele
ments and a modulation-demodulation technique within the amplifior. The modulator-
-demodulator channel is solid state, the dc amplifier uses tubes. A block diagram of
the system is shown in figure 1. The design of the modulator is based on the nonline-I
ar voltage dependent junction capacitance of special pn diodes (varicaps). Principles
of operation, characteristics, and specifications are outlined. The demodulator con-
verts the amplitude variations of the input signal into pulse-width variations of a
10OKhz rectangular wave carrier signal, using variable storage time of carriers in
transistors. The average of the demodulator pulses is then taken. Waveforms illustrat,

fier can be made to vary between -100 and +100 volts. The overall amplification fac-
tor of the total amplifier system is 107 at dc and greater than 100 at 10OKhz. The
modulator-demodulator channel increases the system gain by a factor of more than 1000.
Because of the careful design, no special temperature compensation circuits are re-
quired, yet the system performs as specified over a temperature range of 10-600C.

TITLE: Isomerization of Vinyl Cyclopropane in the Presence of Kissel-
guhr (Izomerizatsiya viniltsiklopropana v prisutstvii kizell-
gura)
PERIODICAL- Izvestiya, Akademii nauk SSSR. Otdeleniye khimicheskikh nauk,

ABSTRACT: This is a brief communication on the experiment to determine
the influence exercised by the conjugated double bond on the
stability of the three-membered cycle during the isomerization.
It is known that alkyl cyclopropanes isomerize relatively
easily under the action of a series of catalysts and pass into
an olefin mixture (Refs 3-5). The authors used kieselguhr for
their investigation because in its presence ethyl cyclopropane
is isomerized almost completely at 1200 (Ref 5). The experimentB
carried out with vinyl cyclopropane under the same conditions
have shown thd quite unexpectedly no piperylene was present
in the catalyst. With the exception of the first few drops the
catalyzate showed constants of the initial hydrocarbon and pro-
Card 1/2 duced no adduct with maleic anhydride. At 1500 not more than

10 % of diene were observed in the catalyzate. It was Dbvious
to assume that vinyl cyclopropane is more reaction-resistant
than ethyl cyclopropane. This was, however, refuted-in the
course of further experiments. It was found that the three-
membered cycle which is conjugated with a double bond may be
isomerized in the presence of kieselguhr. The degree of stabili-
ty of the cycle in this case cannot be determined according
to the amount of the forming piperylene since the latter
completely poisons the catalyst. There are 3 tables and 6
Soviet references.
