The windings are as follows: I - 70 x 2 turns;
II - 2 000 to 2 500 turns (step-up winding);
III - 18 x 2 turns. The resistances R 1 and R 2 are
wound, small-size, high-ohmic resistances. The choke ( A p

ABSTRACT: The problem of the development of gels and pastes has attracted
scientists' attention already since a relatively long time.
Opinions on the nature of these systems differ considerably.
It can be shown that the formation of gel can be explained by
the fixing of colloid particles at relatively far distances
by means of telekinetic powers of molecular and ionelectrostatical
origin. There follows the possibility to come to the analogy bet-
ween the transition of substances built up from molecules from
liquid to solid condition and the gelatination of watered brines.
In the latter case the powers of molecule attraction and of the
ion-electrostatic pushing off appear among the colloid particles
instead of attraction and pushing off powers among the single
molecules. The existence of a potential barrier and of a lower
energetic level beyond thic barrier for the case of interaction
of the colloidal particles refers to the possible way of rolax-
ation. By starting from these conceptions the nature of the
Card 1/4 dislocation elasticity can be ascertained, which forms one of the

principle characteristics of the gelatinated system, and the
conduct of the colloid particles in the interior of the gel can
be investigated. For this purpose not only the knowledge of the
interaction in a single pair of particles is necessary but also
of the action of its entity which forms the quasicrystalline gel-
grate. The mutual fixation of the particles at distances which
correspond to the position of the potential cavities, must de-
termine the minimum value of the potential energy of the system
as*a whole at the same time; the minimum value corresponding to
the condition d U / d h - 0. In the case of reversible
Syst
elementary inclination (dislocation) of the system this con-
dition is interrupted and the energetic level of the system will
rise, which corresponds to the known relation U -dR (R - work
of the exterior powers, and F - free energy) and thus the applic-
ation of exterior dislocation forces is necessary. In the case
of small inclination angles it is true that TdR - Tdy (i - dis-
location tension). 2
Consequently T = d E, and the dislocation elasticity G - d-r d F

In this case the system will behave as a gel if the duration of the

spot of the quasi-crystalline grate will considerably exceed
the duration of the exterior influences. In the case of non-
fulfilment of one of these conditions the system will either
decay or its elastic properties will be marked by the liquid ones.
Furthermorelthe charactero f the potential curve of a "sample"
particle as approximation value is investigated, the "sample"
particle having two firmly established neighbours k and C. Here
the depth of the potential cavity U, which is conditioned by
the fixing ~of the particles in the knots of the grate, will be
considerably larger than in the case of an interaction of two
single particles. In the case of a collective interaction, the
potential cavities for intermediate particles will exist even
ifthe powers of,pushing off on any distances will exceed the
powers oIf attraction. It is natural that cavities of this kind
can only lead to a mutual fixing , of the particles of a coi-
loidal system on certain distances if the environments have a
confined volume, which ftxes the maximum distance of the exterior
particles of the disperse phase. Moreover, a certain minimum
concentration is required, for otherwise the depths of the cor-
responding cavities as compared with the energy of BROWN's motion

TEXT: The thermodynamical potential of a two-component solution can be ap-
proximately expressed if real intermolecular interactions are replaced by self-
consistent external fields. Then the mean values of these self-Gonsistent fields
will enter the expression for-the thermodynamical potential. This makes it pos-

behavior of the solution to behavior of the "ideal" solution. The same considera-
tions are employed for-a qualitative study of distribution of a dissolved sub-

TEXT: The modern theories of osmotic effects are considered. It is
stated that the present explanations of osmosis and osmotic pressure of
solutions are not satisfactory. For systems located in external fields
of force it is shown by means of thermodynamic methods that osmosis is due
to a change in potential energy of the solvent molecules when the solution
is formed. This change Is caused by an entropy effect an well as by a
change in the energies of interaction of the solvent moleculeag with one
another and with the molecules of the dissolved substance. It the changes
of these energies compensate each other, osmosis is due to entropy effects
only. In thin case the extremely dilute solution will satisfy van't Hoff's

law. It is shown that osmotic pressure, surface pressure and swelling
pressure are due to effects that have the same origin. [Abstracter's

TEXT: The cvtuaes of the different volumes of sediments of polymer
suspensions in various liquids were examined. For this purpose, the
sedimentation volumes of spherical p4rticles of pol mers (polychloroviftyl,
fluoroplast-3, polyethylene, and a-polyoxymethylene~ which do not aggregate
during sedimentation, were measured in air (volume weight), water, ,
toluene, xylene, and cellosolve. The different volumes of sediments were
found to be due to the molecular component of the disjoining pressure of
the layers of the liquid between the polymer particles. The disjoining
pressure is directly dependent on the energy of interaction between the
dispersing medium and the surfaces of particles of the disperse phase.
