ABSTRACT: First the distribution of the thermodynamic degrees of freedom in
systems v7ith a non-maximal order of the concentration matrix in dealt
%vith. Referring to ref. 2, it is sho%m that a whole series of heterog-
eneous, systems with many components with a defect of the matrix 6,> 0
am exist. It vms shown that the case (5 = i at r < n, dealt with by
Gibbs [Ref.1] and Storonkin CRef-3-7, is only a special case, where~Ls
t.he nwnber of possible thermodyna~lc systems withd > 0 is essentially
greater. Certain heterogeneous systems vith many components and with
both a pressure- and temperature extreme, such with equal composition
of concentration of various phases (e.g. of phases in points of
equal oc,ncentration, of allotropic phases), as well as some systems
Y/ith many components where not all components participate in the in-
dividual. phases of the system, belong to these systems.

phase (n and r is the number of cmTonents, or of the phases of the
cystem respectively) it is assumed that the defect d of the concen-
tration-matrix is equal to zero [R-ef. 1] . The inequality r -\, n + 2,
ziet up 'by Gibbs, can be generalized for all these enumerated systems.
For this purpose the value X (kappa) is introduced. This is tlae
11reatest of the numbers r - n and 0. X = max fr - n, 01 and the ine-

+ 2, or the monovariant-aetermination of the variables at
+ 1, in the eneral case does not belong to the whole equa-
tion-system (5) to M, but to an individual group of this system
of equations. The generalizing terus of the nonvariant and mono-
variant state of a thermodynamical system are given in the second
part of the work. It is shown that at 6 + I = 2 in the thermodynam,-
ical system a certain group of phases which is in nonve.riant equi-
librium (y -_O) with each other, must be contained, whereas all other
phases of the same system in the general case can have a degree of
41
Ireedom Y2 = y >/ 0, different from zero. Thereby, the total amount
of degree of freedom of the thermodynamical system is equally equal
to y, and can be greater than 0: y > 0. Such a state of the therm-
odyaamical system, in which case a part of the phases is in nonvar-
iant equilibrium, whereas the total-amount of thennodynamical de-
grees of freedom of the system y in the general case can be differ-
ent from 0, is called by the authors the'nmvariant ste.te of the
thermodynamical system. consequently, the conception of the nonvari-
ant state of the thermodynamical system is a more general term than
Card 3/4 that of the nonvariant equilibrium, provided that the total amount

Order of the Concentration-katrix
of the degrees of freedom of the system is equal to zero. In the
special case y = 0, all plvases of the given system are in nonvariant
equilibrium. In such a case the terms of nonvariant state ana non-
variant equilibrium coincide. Analogously it is shown that a thermo-
dynamical system at G~ + X = I is in monovariant state, i.e. it
contains a certain group of phases which are in monovariarrb equi-
librium (Y - 1) eLth each other, v-hereas the other phases of the
system in th-e general case have a greater number of degrees of free-
dom. Concluding, examples are given. There are 3 Slavic references.

ABSTRACT: The terms V, S, P, T mean: volume, entropy, pressure and
temperature of the total heterogeneous system. M, and~2tl, on
the other handp mean the quantity and the chemical potential
of the i-th-component in the whole system; further v,, aj, m

denote the specific volume, specific entropy and the mass of
the mass of the J-th-phase of the system; x and p are the

J-th-phase; n and r denote the number of components and the
number of phases in the system. In the case of an analytical
study of the thermodynamic systems it is usually considered
a foregone conclusion that the rank of this matrix is a
maximrm, i.e. that its defect is a = 0. Thus the phase rules
and the inequality deduced by Gibbs r 0 + 2 concern only
such thermodynamic systems with (Y - 0. One can$ however,

They wexe mentioned by Gibbs and discussed more in detail
by Storonkin. As may be seen from the following, the case
of a system with 6 = 1 at r4,(n is only a special one, an&
the number of possible systems with a> 0 is cons iiderably
higher. To this belong certain thermodynamic systems with a
pressuxe- and temperature maximum, with equal concentration
composition of various phases, some systems in whose individual
phases not all components participate. It is the purpose of
the present paper to determine the rules to which the systems
with 6 ~O are subjected. If any additional conditions are
added i;o a thermodynamic systeml these conditions have to be
added apparently to the equations of Gibbs-Duhm or to the
equality of the chemical potentials before computing the
number of the thermodynamic degrees of freedom of a system*
In the present case the additional conditions are those
connected with the equality of the defect of the concentration
matrix by the value 0, where 6~0. Furthermore the equations
of the chemical potentials are discussed together with the
above-mentioned conditions. Then follow in an analogous manner
the equations of Gibbs-Duham together with the conditions of
the nort-maximum of the matrix rank. From the results obtained
the meaning of the conditions 0\< a +)((2 (7) becomes clear.

ABSTRACT: The modes of Erovith which can result in a periodic
impurity distribution are discussed in relation to
possible causes, and a phenomenolo-ical theory is
proposed. Experimental data given by others on NaI(Tl)
and Sb in Ge (grown by the Stockbarger and Kyropoulos
technioues respectively) are considered. The effects
are discussed in terms of the supercooling required to
continue crystallization as the 'impurity' is rejected
by the growing crystal and accumulates ahead of it,
followed by a fresh nucleation as the supercooling
passes some critical point. This scheme is considered
in relation to Figs. 2~ 4 and 5 (Figs, 1 and 3 relate
to the experimental data referred to above),, Much of

ABSTRACT: Firstly, the difficulties encountered in the ordinary chemical-
or physicochemical analysis of the concentration compositic-n of
the phases of heterogeneous m!11ti-ccmponent systems are exposed.
In this paper, an analytical method of deterraining the chernicel
composition of the phases of equilib_rium multi-component hi-.terc.-
geneous systems is advanced, which does not necessitate a c~emi-
cal or physicochemical analysis of these phases. This met-hod
operates with measurements of the phase masses. It is based upon
the application of the generalized "center of gravity" rule
(Ref 1) and it represents the moat simple method f-.r the case
under review of heterogeneous r-phaae, n-component systems, the
number of phases r being equal to n, n + 1, or n + 2, This method
requires a number of r different experiments. In each of these ex-

equation of state for the strongly compressed matter at very high temperatures
is assumed. energy-den~ity = 3-pzessure. The total number cf partic,"es
amounts to about V/4 (B - energy of the nucleons in the laboratory system.).
It follows the establishment and the discussion of the ehergy LU-stribution

TITLE: Transistorized differential D.C. amplifiers
PERIODICAL: Automatica si clectronica, v. 6, no. 1, 1962,12-18
TEXT: The three main causes of thermal drift of a transistorized D.C, amplifier, namely variations of
lc,,, of E,F, and of fl are discussed. In order to decrease drift, differential D.C. amplifiers are widely used.
Circuit diagrams of differential D.C. amplifiers with symmetrical and unsymmetrical (phase inverter) inputs
are given, and their equivalent circuits are discussed. The procedure for computation of the phase inverter
amplification is given in the appendix.The author has built and c)iccked both types of differential D.C. ampli-
fiers, as well as a 3-stage differential D.C. amplifier. In order to reduce the thermal drift, transistors of'similar
I.R. were selected. For the first stage of amplification transistors with lowest 1,30 were chosen. The con-
structed amplifier was intended for production of D.C. and A.C. regulators. EFT 153 transistors, produced V12
by Uzina Electrica (Electrical Factory), have been used. The experimental results showed that by use of
transistorized D.C. differential amplifiers, a high amplification factor and a sufficient reduction of thermal
drift are obtained, so that these amplifiers may be used for automatic regulation and simulation circuits.

TITLE: Carborundum varistors without a binding agent
PERIODICAL: TelecomunicaVii, no. 1, 1960, 16-20
TEXT: The article presents the results of investigations conducted
at the Institutul politehnic (Polytechnical Institute) in Bucharest
into producing carborundum varistors without a binding agent. These
varistors consist of a cylindrical container with two electrodes,
into which the carborundum granules are introduced. The apparatus
is provided with a mechanical device for compressing the granules.
The voltage-current characteristics of different typez; of varistors
are shown in Fig. 4 for the linear scale, and in Fig. 5 for the
double logarithmic scale. Mechanical vibrations have a negligible
influence on the parameters of the varistor if the material is suff-
iciently compressed. For varistors operating --t voltages below
100 V, it is recommended using electrotechnical carborundum, whereas

for varistors operating at voltages above 100 v, it is recommended
using green silicon carbide. The dynamic characteristics of the
varistor were established by a cathode oscillator and the wave shape
of the current was oscillographed. Up to 20,000 cps,the wave shape
of the current remained unchanged. Measureds were accomplished at
a-c (f - 50 cps) by the armeter-voltmeter method. The following
conclusions could be drawn from the measurements: After having es-
tablished the first curve and returned to the initial temperature,
the resistance to the initial temDerature increased. The differences
between the R = f (TOC) curves established initially and subse-
RO
quently, were low for temperature values close to the inital one,
but increased at higher temperatures attaining even 5,'o. The LI =
Ro
f (TOC) curves established finally coincided with the curve establi-
shed for the second time. The value of resistance to the initial
temperature coincided in the case of curves established for the sec-
ond, third, and fourth times. The admissible dissipating power of
varistors with a diameter of D = 3 cr,.i, was 6 w, and that of varis-
tors x7ith a diameter of D = 7 cm, IU' 1-7. The manufacture oi- vris-

TITLE: Binderless carborundum varistors for low voltage
PERIODICAL: Telecomunicatii, no. 3, 1961, 107-109
TEXT: On the basis of their previous publication on various types of
varistors without binder (Ref. 1: Telecomunicatii, 1960, no. 1, p 16-20),
the authors present some experimental results obtained with binderless
varistors operating at low voltage. The experiments were conducted with
cylindrical varistors, with containers having an internal diameter of
70mm. The carborundum consisted of 0.1-mm granules. The decrease of the
voltage, at which the curvature of the voltage-current characteristic
appears, was achieved by reducing the thickness of the carborundum layer
to a minimum of O-4mm. For a linear section the formula
log U = log C + 01-log I

Binderless carborundum varistors for low voltage
may be used, hence:
U = Cf (2)
or
I = AUn (3)
In the formulas (1), (2), and (3), A and C are constants, while n IS
the quality-factor of nonlinear resistance. The formula (2) shows that
if I = 1A U = C. Table 1 presents the experimental values of C and of

he actors(x and n in binderless varistors. Comparison of these results
with the characteristics of varistors with binders shows thatt(l) with
binderleBs varistors nonlinearity coefficients comparable to those of
varistors with binders may be obtained, but at a much lower voltage;
(2) starting with the C value of 20, the c4coefficient of varistors without
binders has the same value or even a higher one than that of varistors with
binder and (3) with binderless varistors C values up to a minimum of 6,

Dinderless carborundum varistors for low voltage
with a quality factor of n~~2.6 -+- 2.7,may be obtained. Experiments
proved that the voltage-current efiaracteristic of binderless carborundum
varistors in a double logarithmic scale forms two straight-line segments;
the curving of the characteristic, however, takes place at s*~:$2 v, while
the curving of.the voltage-current characteristic of varistors with binder
takes place atl;;zr,50 *, 100 v. On the first section of the voltage-current
characteristic in the double logarithmic scale the quality factor n is
lower than on the second section. Accordingly, in a binderless varistor
with C = 6.5, n is 1.86 on the first and 2.66 on the second portion. Low-
voltage varistors are used in error transducers for d-c voltage regulators
with transistors and for limiting excess voltage in inductive circuits.
Varistors without binder are successfully used in assemblies with tran-
sistors requiring the.use of low-voltage non-linear resistances. There
are 5 figures, 1 table and 3 references: 2 Soviet-bloc and 1 non-Soviet-
bloc.

ABSTRACT: The paper gives practical details for a study of the
problem of homogenisation of miscible substances by
mechanical mixing. The rate of homogenisation of NaCl
in a large volume of water (or aqueous glycerine
solutions)'is followed conductiometrically. The electric
circuit cf the apparatus and some results obtained are
given.
There are 3 figures and 5 references, 1 of which is
Czech, 4 English.
