short (Fig. 1). When representing the symmetric cols special importance
must be attached to the ratio between length and width of the col. This
J_s done by means of auxiliary contour lines (Fig. 2). The use of ar-
bitrary contour lines, even on topographic maps on a scale of I : 25,000
is regarded as inexpedient. The asymmetric cola are formed both on
basic rocks as well as on the loosened sediments with inhomogeneous
geological str,icture under the action of various denudation agents and
of regressive erosion. They are characteristic of the reliefs of folds
and cuesta forms, especially of sandstone and ravine forms. Besides, the
asymmetric cols occur in karst, suffouion, solifluction, glacier, and
other areas where the valley-side slopes and the slopes of water divides
are usually unsymmetrical. The asymmetric cola can be dilided into
three subforms: asymmetrical with respect to length, asymmetrical with
respect to width, and forms with complex asymmetry. The former two
are formed in areas where the rock composition changes along a divide
or where the axis of tectonic disturbances runs along a divide (Fig. 3a),
and in areas with horizontal rock stratification with regressive erosion
(Fig. 3b) and in areas with a karst, solifluction, suffosion, and ravine
formations. The cols asymmetrical as to their width, are formed in areas

where the change of. rock composition or the axis of tectonic disturbances
lie in transverse direction to the water divide. This anticlinal form
is observed in areas where solifluction terraces (Fig. 4) and glacier
forms occur as well as in areas with radial water system. Cols with
complex asymmetry are mainly formed on loosened accumulations and rooks
(Fig. 5). In many cases the asymmetric cols cannot be represented by
main contour lines, hence auxiliary contour lines and even arbitrary con-
tour lines must be used. There are 5 figures.

TITLE: Ultrasonic Defectoscopy on Turbine Reductor Gears
PERIODICAL; Elektricheskiye stantsii, 196o~lNo. 9.
pp. 24 - ,14 A
TEXTS Use of various magnetic methods (for instance,
magnetisation by an induced current from -a closed core or
magnetisation by a current pulse) as well as the luminescent
method of defectoscopy did not yield positive results since
all these methods are essentially suitablo for detecting
surface defects. Application of ultrasonic defectoscopes is
satisfactory for the rim of the gear but it did not prove
satisfactory for the teeth. This is attributed to the fact
that the quantity of ultrasonic energy entering 'the gear teeth
is too low to produce, even with maximum amplification, a
vertical "peak" of the reflected signal on the oscillograph
screen. Therefore, the authors applied for this purpose
apparatus based on resonance. The instrument works on the
following principleg ultrasonic energy of a variable
frequency (3 to 6 Mc/s) is beamed into the material to be

tested, using a piezoelectric transducer. 4t a certain
frequency that corresponds to the frequen.-y of the natural
oscillations of the material (with respect to depth) being
tested standing waves will form with nodes located at the
surface; thereby, ultrasonic waves will be fully reflected
from the surface,. In this case the oscillator is tuned to
be in resonance with the thickness of the material, At maximum
reflection of the ultrasonic waves the piezoelectric trans-
ducer which is applied to the component will oscillate with an
amplitude many times that of oscillations generated in it by
a single generator, i.e. a maximum release of power occurs, as
a result of which the piezoelectric transducer will be subject
to sharp load changes. This, in turn, will affect the
operation of the variable frequency oscillator in whose cathode
pulses are being formed, These pulses are fed to the vertical
plates of the oscillograph. The horizontal plates are fed
with a voltage that is proportional to the variable frequency
of the ultrasonic oscillations, As a result, pulses will beloscenpJ
on the screen, the character of which will indicate the presence

Ultrasonic Defectoscopy on Turbine Reductor Gears
or absence of a defect in the ma terial. This instrument,
LA~4_~gp (v4-8R), is basically intended for measuring the
thickness of metallic components in the case that access is
available from one side only and is used for determining
differences in wall thickness, detection of layering in
tubes and rolled sheets, controlling the quality of brazing
and glueing of metals. The search for defects is carried out
in two stages, one for the teeth, using the above mentioned
resonance defectoscope and one for the rims, using an ultra-
sonic defectoscope operating at a frequency of 2;; Mc/s and
a prismatic probe with a reflection angle a = 4 .
Experimental use of the resonance defectoscope on specimens
with artificial defects has shown that the sensitivity of the
instrument is sufficiently high and defects in the root of
the teeth with an equivalent area of 2 mni could be easily
detected by this instrument. Practical experience has shown
that reduct3on gear pairs should be subjected to ultrasonic
inspection after having been in operation for 50 000 to 60 00o
hours.

TEXT: Blading of reaction turbines is more subject to
erosion than that of impulse turbines. The cheapest and simplest
way of protecting the blades is electric-spark hardening of the
inlet edges proposed by TsNI1TMASh, with which the hardening can
be carried out directly on the rotor. A'pr!bcess isdescribed
which increases the service life of blades by a factor of 2-2.5.

Title : The Upper Curie Point for Rochelle Salt.
Orig Pub : Zh. tekhn. fiziki, 1956, 26, No 7, V43-145o
Abstract : The hysteresis loops of Rochelle sall; cTV tals (I) were
investigated at temperatures from 18 to 466 in electric
fields up to 45 kv/cm at a frequency of 50 cycles. It is
shown that the hysteresis phenomenon in strong fields con-
tinues to exist also at T ;:> 240. In the authors' opinion,
the spontaneous and residual polarization at the Curie
point do not cpase, and the magnitude of the polarization
is connected with the intensity of the electric field.
Since the spontaneous polarization turned out to be the
same fro various electric field intensities for an the
investigated temperatures, it is concluded that the

is shown that the hysteresis phenoueaon lasts in strong fi.elds
even Ltt ternneratur2s above the upper Curie point (240). In
strong fields, the values of spontanaous and residual polariz-
ations are equal at all temperatures, i.e. the mechanism of
polarization at temperatures < 24 and 1,1 240 is the same. The
higher the temperature, the stronger the fields must be to
produce manifestation of ferro electric properties, i.e. the
authors suppose that the time of relaxation of the processes
of polarization grows with the increase in temperature. In con-
clusion :.t appears that there is no upper Curie point for
Sei-retta's salt and it is supposed tbat a low Curie point does
not exist either. It is demonstrated that -there is no analogy

ABSTRACT: The pyroeffect in polycrystallic i3amples of barium titanate
and its connection with the piezo(?ffect was investigated.
One of the experiments ran as followei a barium titanate
sample was subjected to polarization during 5 minutes with a
field of 1,600 v/mm intensity at '200C, and then its electrodes
were connected by a circuit with a galvanometer. Immediately
after polarization, a current could be detected in the circuit,
even at the constant temperature of the sample, but very soon,
in 30 min., it became immeasurably small. The statical pie 0-
modulus of the sample was measurel and proved to be 1.2X10-9
CGSU.

Then the sample was heated and pyrocurrent was generated.
The curve of current intensity, shown by Curve 1 in Fig 1,
had 2 maximat one corresponding to the transition of the
titanate lattice from the orthorhombic modification into
tetragonal one, and the othert at Curie point, i.e. 1200C,
corresponding to the transition into cubic modification.
The sample was cooled down and thoin subjected to the second
polarization under the same oonditions bxt during 30 min. The
piezomodulue was measured to be 1,56x10- CGSU. By heating
the sample, the pyrocurrent was goinerated again, and its run
was shown by Curve 2 in Fig 1.
The quantity of electricity generiLted was proportional to the
value of initial piezomodulus.
If a sample subjected to polarisai;ion is heated to a temper-
ature lower than the Curie point, and then is cooled down,
the pyrocurrent arises both during heating and coolingl the
quantity of electricity flowing in the circuit during heating

ABSTRACTt In the growing of barium metatitanate crystals light yellow to
dark brown (almoat black) crystals are obtained. The nature of
the coloring of these crystals is similar to the nature of the
coloring of the alkali-halide crystals and the halide salts of
silver. The already earlier observed blackening is connected
with the partial reduction and elimination of the metal. The
coloring discovered by the authors proceeds otherwise and is
a merely physical process which is connected with the displace-
ment of the current carriers. The samples were produced accord-
ing to Mattias's method, the properties of these samples are
shortly enumerated here. The absorption was measured by the
photospectrometer CF-4. A diagram Rlustrates the absorption
spectrum of a dark brown single crystal. This crystal was

ducing part of the flame of an alcohol burner), whereby it
became almost transparent with a slightly yellowish coloring.
For this case the absorption spectrum is also illustrated by
a curve. After the heating in air or oxygen the spectrum anew
takes a brown-red color. This color can, an analogy to the al-
kali-halide crystals, be designated as additive. The coloring,
known from the alkali-halide salts, under the infllience of a
field is also observed in BaTiOll The various changes of color-
ing are described. These crystais can be aiored by means of an
alternating field. The velocity of the spreading of the brown
color is strongly dependent on temperature. (At room tempera-
ture 1 mm per day at am electric field strongth of E w 10 O/cm~
The coloring under the influence of the field and the coloring
by oxygen reight be due to the same coloring centers (Farns-
worth centers?). The color of the single crystals changes their
electzic properties. There are 2 figires and 7 references, 5 of
which are Slavic.

ABSTRACT: The investigation of the optical properties of the region near
the electrode of crystals during electrolysis is of great inter-
est. The authors investigated samples of HaCl-, KC1-, KBr- and
KJ-crystals. Thc, largest surfaces of these 12xl5x5 mm sampleslae-
re polished and then electrodes of a lo,,'~~thick aluminum foil were
tightly pressed to them. The symples produced in this manner we-
re heated to constant temperatures between 45o and 6ooOC and ex-
posed to a constant electric field of 50 to 400 V/cm for some
minutes to one hour. In this connection the following was measurv
ed: the intensity of the current passing through and of the in-
verse current, the potential difference at the unshortened sample.
The variations of amperage and field strength in time are illust-
rated by a diagram. These processes Imay be f3ubdivided into two
phases: In the first phase the amperage first decreases and then
remains constant. The intensity of the inverse current and the

their maximum during that time anIthen stay constant. During the
second phase the amperage usually increases and the sample is on
that occasion colored by F-centers. The duration of the fi,,-ijt
phase depends on the duration of the cathode- crystal contact and
on the applied voltage. When the contact is increased the phase
decreases to a certain minimum value and it also decreases with
increasing voltage. The absorption spectrum of the sample was in-
vestigated before and after the electrolysis at room temperature.
