ABSTRAM The method by Shchukarev and Myuller (Ref 1) for the measuring of
the electric conductivity of glasses may be regarded as the most
rigid method. The authors had to find out whether the measuring
results in using graphite or silver electrodes agree with those
where amalgam electrodes were used. The solution of this problem
would determine the quality of this or that method, moreover, it
would make possible the evaluation of the experimental data from
publications. At present the following measuring method is used
in the institute mentioned in the Association: the samples have
the shape of disks with plane parallel surfaces to which round
graphite electrodes are fitted. The measuring cell consists of 2
main parts& a furnace and a lid. Their construction is described
in detail. As compared to earlier constructions (Refs 2,3) i~ ahows
Card 114 several advantages. The measurements of resistance (below 10 ohm)

are carried out by means of alternating current (1'requPncy: 50 cycies)
by a bridge for the measuring of capacitances and resistances. In
the case of higher resistances direct current and a me&ohrmeter
LN-2 are used. Both devices are bridge connections. In both cases
6E 5 lamps serve as equilibrium indicators. In the investigation
of the electric conductivity the method mentioned in reference I
was considerably simplified. Figure 2 shows the construction of the
smal&am electrode. A stabilized constant voltage was applied to
the sample. The resistance of the sample was measured by recording
the passing voltage by means of a micro-ammeter. It can be seen
from table 1 that in the case of a prolonged passing of the voltage
the resistance of the sample decreases to a certain extent even if
the temperature of the hot junction of the thermocouple remains
constant on the surface of the sample. The authors assumed that
the resistance decreased due to the heating of the jample by the
passing voltage. Therefore the authors interrupted the voltsEe for
20 minutes and then measured again the resistance. Table I r 'eveals
that after the interruption the resistance had increased again to
the original value. A control computation has demonatrated that

of the Electric Conductivity of Glasses
it can be concluded that the values of the resistance at the first
moment after the switching an of the voltage can be regarded as the
real resistances. Figure 3 shows measuring results of the resiut-
once at various temperatures at the first moment after the switch-
ing on of the voltage. The dependence of the resistance on tem-
perature proved to be linear as expected. Resistances measured with
direct and alternating Current proved to be the same. Fieure 3
shows also measuring results when graphite electrodes were used.In
contrast to the existing opinion silver electrodes cannot be re-
garded in any case as reversible (Fig 2). The authors arrived at
the conclusion that graphite electrodes show the same results as
amalgam electrod*s. Since the first considerably simplify the
method it is not expedient to use amalgam electrodes for the men-
tioned purposes. There are 3 figures, 2 tables, and 4 references,
3 of which are Soviet.

ABSTRACT: An investigation of the vibrations of the blades of large turbines
which lead to the rupture of the blades and the tearing of the banding.
Solutions are adduced for the differential equations of the torsional
vibrations for groups with a finite and an infinite number of blades
of constant section. The great amount of scatter in the vibrational
frequencies in various shapes of a single mode is noted; this scatter
is confirmed by experimental data. Differential equations are adduced
for the torsional vibrations of blades having a variable section; these
are solved by the method of successive approximations. A method is
provided for the determination of the relative stresses arising during
Card 1/1 torsional vibrations in a blade and in the banding. K.S. Pul'kis

PZRIODICALt Energomashinostroyeniye, 1960, No-7, PP-1-5
TEXT: 9xperimentally-determined values of the natural frequencies
of bladed rotor discs are always lower than the calculated values.
The difference in attributed to the circumstance that the
theoretical calculations made no allowance for the reduction in
axial frequency due to natural twisting of the blades. If, on
the other hand, allowance is made, then the calculated blade
frequency values fall iftto good agreement with experimental
values. In making these calculations of the natural frequency
of bladed discs, it-is necessary to know the curve through which
'they bend during oscillation. A blade with natural twisting and
In the unstrained state is then considered theoretically in a
system of coordinates that passes through the centre of gravity
of the root section. Ons, axis is made parallel to the axis of
rotation of the rotor, the second is perpendicular to it and the

third in in the plane of the blade. The differential equations
of blade bending allowing for natural twisting are of the form
of Eq.(2). When this is substituted into the expression for
the moments acting in the blade section relative to the main axes
of inertia, Zq.(3) in obtalned. This exprezzlon Is the
differential equation of oscillation (static bending) of a natural
twisted blade. When a bundle of blades interconnected by three
lacing wires is then considered, Eq.M assumes the form of Eq.M,
which is integrated with appropriate boundary conditions to
obtain Eq.(10). In this way, the first approximation to a
solution of Eq.(7) is obtained and is shown to be of satisfactory
OCCU'racy. The method of calculating the shape of the oscillation
at the second (axial) frequency is then explained briefly and is
very similar. In this case, it is necessary to use the second
approximation to the solution, A calculation is then made of the
resonant frequency of a bladed disc with twisted blades. The
method of calculation is one developed by the author for rotors

TITIZ: Torsional oscillations of runner blades
bound into a bundle
PERIODICALs EnergomAshinostroyeniye, jL9619 N0.8t pp. 1-4
A
TEXTs The theoretical investigations of this article show
that whereas an individual blade has a single mode of oscillation
for each frequency of torsional oscillation, n blades laced as a
group have n modes of oscillation. Blades in the group may
oscillate at different amplitudes depending on the mode of
oscillations oscillations of this type are termed 'tinter-bundle
torsional oscillations". For each harmonic the frequencies of the
different modes of oscillation are very different from one another.
In this respect, torsional oscillations differ from bending
oscillations of bundles. The wide frequency range of inter-bundle
torsional oscillations of various modes of a given harmonic, which
is confirmed experimentally, makes it difficult to detune to
prevent resonance. particularly as the lacing wire, though it may

modify certain frequencies, does not render them impossible, as in
bending oscillations. Fig.1 shows the modes of torsional
oscillation (angles of twist) of the third harmonic of a group of
seven blades of constant section laced by two wires, and Table 1
gives the frequencies of the fundamental frequency, the second and
third harmonics of this group. At the maximum frequency for each
harmonic all the blades twist in the same direction and differ from
one another only in amplitude. At this frequency the mode of
oscillation approximates to the mode of torsional oscillations of
an individual blade, or to that of a group with an infinite number
of blades in which all the blades oscillate under identical
conditions. Accordingly, the upper limiting frequency for each
harmonic may be determined by considering a group with an infinite
number of blades. Thus, for the group which is the subject of
Table I the frequency determined on the assumption of an infinite
number of blades is as follows:

Fig.2 gives curves of the relative stresses in the third harmonic
of torsional oscillntion in blades of a group laced by two wires,
and Table 2 given the ratio of the istress in the upper wire to the
stress in the lower one. It will be seen from this table that for
the fundamental and third harmonica these ratios-do not alter.much
for different modes of oscillation, whereas for the second harmonic
the ratio varies from 1.i to 3.27. During torsional osclilationso
of groups of blades the bending stresses in the lacing wires are
much greater than the blade stresses; this is undoubtedly a cause
of wire breakage in practice. The differentidl equation of
,torsional oscillation in the closed form can only be solved for
blades of constant section, for which the equation is -of the foim

ABSTRACT: An Author Certificate has been issued for a thermal-'and acoustic-
Insulating covering for cabins and compartments in transport aircraft, the skins
of which are made up of sections of longitudinal and transverse load-bearing units
using porous material laid onto the skin in one or several layers. To better
utilize the thermal- and acoustic-insulation properties of the materials (e. g., of
ultra th:h glass wool), to facilitate installation and removal, and to protect
cooled surfaces from water condensation, the covering is made in the form of
separate blocks coated with a waterproof film. These blocks are then placed in the
section frames of the skin and secured to the latter around the edges by a plastic
strip having an adhesive layer which provides hemqtic sealing and ease of removal.
PolvisobutIlenell or some other nonsetting adhesivdiFis used to bond the blocks to the

Abstract : This is a commmication on the vascular responses in can-
cer patients studied by plethysmography. It was determi-
ned that vascular unconditioned and orientation responses,
as well as responses to verbal signals, were decreased;
this indicates a depression of excitatory processes in the
cerebral cortex.
