ABSTRACT: During normal operation of heatinc, baths, the salts
have a tendency -to age and they become unsuitable for
heat treatment if no fresh salts are added.
The author of this paper investigated some saltpetre
media which are most frequently used during isothermal
and step-wise hardenin6 and also during tempering of
steels. For determining the heatin6 properties of Hlten
salts, a mercury thermometer with a scale up to 500 C was
usedl the end of which was fitted into a steel ball of
33-85 mm dia. By means of this-device the heatinb
capaoity of saltpetre baths at 400 and 5000C .,ias determined
as a function of the degree of ageing, the cheiaical
composition and other factors. For this purpose -the
ball ser'ving as a thermometer was subiaer6ed into the
molten media and readings-were made every 10 to 15 secs

curves viere graphed; simultaneously chemical analyses
were made of the saltpetre baths., The test results of
saltpetre,baths at various stages of ageing, under plant
,conditions, are graphed in FiG.1 In Fig.2 the influence
is Sraphed of barium,nitrate on ;he heating capacity of
an ased-,bath-. 'in Fig.3 the heating capacity is graphed
of fresh saltpetre media and of molten lead. It was
found that addition of chlorides (NaCl, KC1, BaCl CaC12)
increases the oxidation ability of the saltpetre ~e'dium
and, therefore intensifies the ageing process and does
not bring about an improvement in the heating properties.
Addition of NaOH,or KOH.to saltpetre mixtures also
intensifies their ageing. Sodium Eitrate is not
recommended for temperatures of 500 C and hiE;her since
it dissociates easily aad the sodium oxide thus generated
causes ageing;thus,addition of sodium nitrite does not
improvethe heating properties. Admimtures fallin6 into
the bath in the form of 'iron oxides intensify the ageing.
~Exzperimen'ts were also made for obtaining information about
the rational choice of the composition of saltpetre baths.

mix~iire at 400 0 amounts to00.9-1 C/sec 9d for the same
media the difference a~ -500 C is only 0.1 C/sec. Thus,
at temperatures of 500 9 &nd,abo-te any composition of the
saltpetre bath is applicable.""'Ihe following conclusions
are arrived at:
1. The heating ability of saltpetre baths depends on
the degree of ageing, the older.the.bath the less is its
heating ability.
2. For regeneration of salts of ageing baths it Is
~necessary to add periodically non-aqueous barium nitrate
in a quantity depending on the chemical analysis of the
bath.
3. The salts NaCl, M and the alkalies NaOH and KOH
should not be used as additions since they intensify the
chemical activity of the saltpetre medium and bring about
ageing,of the bath.
A If the saltpetre baths are intended for operation at
4~0-520vC and above sodium nitrite should not be used as
Card 3/5 an admixture due to its inadequate stability. If these

bat 4s operate at relatively low temperatures (200 to
300 0) addition of sodium nitrite is advisable.
5. The lower the temperature of the saltpetre medium, the
greater the difference between the heating properties of
the molten components and their eutecti8 mixture.
Therefore, at low temperatures (200-300 0) the bath
should be maintained at exactly -the eutectic composition.
In 8he case of operation of saltpetre baths at 350 to
45b C deviations from the Sutectic composition are
permissible. At 450-520 C and hi6her it is possible to
operate solely with potassium or sodium saltpetre baths
or any mixtures of these.
G. For increasing the service life of Baltpetre baths
with operating temperatures of,450-520 C and above,
particularly those containing predominantly sodium salt-
petre, it is necessary to clean frequently the silt out
of the baths.

ABSTRACT: The process of ageinS of salt baths (consistino of NaITO 3
and ]KNO-
.,,) during thermal treatment of steels, methods
of bathregeneration, the role of additions and
admixtures and a rational choice of the bath com-Dosition
veie investigated. The experimental results are shown
in Tables 1-4. Conclusions: When 8he bath is operated
within a temperature range 300-350 C its composition
should be kept near to thS eutectic composition in the
temperature range 350-450 0 deviations from the 0
eutectoidal composition are permissible; at 450-520 C
the maintenance of the eutectoidal composition is not
necessary. In order to increase the service life of
saltpetre baths faith an operating temperature 300-5200C
and above (particularly when sodiuru nitrate is thq
predominant comDonent) a mechanical cleaninG of the bath

remove.ferrites, perferrites and manganates from the
liquid phase by additions of boric acid or potassium
bijhromate or anhydrous barium nitrate, should be carried
out often. Under operating conditions 450-5200C and
above additions of sodium nitrite are not advantageous
as it decomposes easily increasing the alkalinity of the
medium and, therefore 1he rate of aging of the bath.
Under operating conditions of 200-300 0 an addition of NaN02
to the saltpetre mixtures is necessary, as the latter
decreases the melting temperature of the medium without
undergoino at this temperature a strong decomposition.
Chlorides (Naql, KC1) and alkalies (NaOH, KOH) should not
be added to the saltpetre baths used for heat treatment
of steel as dhlorides and alkalies increase the chemical
activity of saltpetre mediums and accelerate the ageing
of the baths. Iron oxide admixt-ares, brought into the
saltpetre baths by articles treated, accelerate the
Card 2/2 ageing process and therefore should be often removed from
the bath. There are.4 tables.

ABSTRACT: In the machine building industry of the USSR nitric baths are more
and more used.for heat treatment. As, however, the chemical processes
occurring during this.treatment have.hitherto not been known, this
investigation was intended to clarify this problem. The author
showed that'the-oxidation process in the nitric bath does not stop
at.~3Fe + 20 = A 0 and,.2Fe 0 + 0-50 = 3Fe 0 but that it pro-
2 3 4' 3 4 2 2 3'
ceeds further and that iron is oxidized to the highest oxygen com-
pounds, it is firstly hepta- and then octavalgnt. Fin,jlly perferrates
are formed; 2Na 2FeO4 (21C2FeO4) + 0 2 = 2-Na2FeO 5 (2K 2peo5,j' in order to
ascertain the processes connected with a protracted staY of the
steel products in nitric baths, steel chippings were heated in nitric
baths through 1, 29 3, and 5 hours at 5000- It was found that the
Card.1/4 weight of the chippings increases and that their color changes to

a velvety black. If heating is prolonged even further the weight
decreases and the color of theLohippings changes to a black or
dirty rust shade.LThe longer.the chippings are kept in the bath,
the more,the weight of.the..chippings WillLreduoe. It was found that
if the steel is kept in the nitric bath for a protracted period the
steel surface will be corroded. This is explained by the formation ,
of the ferrates and of the perferrates of alkali metals. Reference.
is made of another paper (Ref 1) and it is stated that the asser-
tion made in-thatLpaper which is to the point that the perferrates
of the alkali metals exhibit a green color is incorrect. The green
coloring is caused by the presence of manganese.The experiments
which were carried out in the course of this wurk and which are
briefly described demonstrate that these perferrates are yellow.
The reactions for the qualitative ddtermination of manganates and
perferrates of sodium and potassium in nitric melts are investigated.
It is shown that the "soda-method" for the determination of perfer-
rates can only be used.if no manganese and chromium are contained
in the malt. The separation of the manganates and of the perferrates
of the alkali metals is based upon their different reaction towards
Card 2/4 hydrogen peroxide. Aqueous solutions of NaNO 3 and KNO3 salts, which

for~a long time have been-used in the heat treatment of steel and
which were-neutralized with HC11 after a long rest (20 - 24 hours)
again turned basic. According to the author's opinion this can be
explained by the following hydrolytic process: Na 2FeO5 + H20 :g=t~
NaHFeO + FaOH.- It is demonstrated.that the nitric medium
5
of the bath, which initially represented a single-or double-componeat
system,.turns into a multi-component system after having been used
for a heat treatment of steel. The author is of opinion that during
a hardening with isothermal transformation the higher oxygen com-
pounds of iron and manganese are destroyed and lower iron and
manganeseloxides are formed. On this basis the aging process of
nitric baths is explained. Practical experience has fully co=obnated
-this theory, The experiments are described and the analyses which
substantiate this theory are given. This investigation therefore
completely clarified the chemical and physical processes in nitric
hardening baths and showed ways and means of using such baths
correctly and economically. Besides, methods were found of re-
generating such batiis. There are 2 tables and 2 Soviet references,

TEXT: The authors analyzed 80 events of meson production observed in an
emulsion chamber consisting of 180 layers.of HWK~W-P (NIKFI-R) emulsions
(areat-10-10 cm2; thickness, 400 P). This chamber was irradiated for
9 hours at an altitude of 24 km. 120 nuclear interactions with more than
five relativistic particles were found. In each of these stars, the num-
ber of thin (N. ), gray (N 9), and black (Nh) tracks was countedq and by
means of a goniometer the angle,Q 1/2 was estimated, which included half
the amount of relativistic particles. The grains in the tracks were
counted by means of microscopes of the types NSPI-8 (MBI-8),

of the nuclear matter tube when striking this matter out of the nucleus.
2) The anisotropy in the angular distribution of nucleon-nuclear showers
does not decrease with increasing number of excited nucleons. This holds,
at least, for energies of UP to 5-10 12 ev. 3) In this energy range, the
relative probability of accompanying showers as predicted by ChernaVBkiy
..does not exceed 0.04. The "accompanying tube" must not be investigated
independently of the principal one. 4) The angular distributions of
relativistic particles in the showers are homogeneous and can be

ABSTRACT: The authors present-the results of a comparative study of two
methods of determining the actual evaporation from the sur-
face of an orchard of the Kamensko-Dneprovskaya Experimental
Station. The first is the balance method based on a determi-
nation of soil moisture by boring, a calculation of the
moisture stores and precipitations. The secoad is the gradi-
ent method developed by A.A. 3olopko and already tested in
practice by the Institut less. (Forestry Institute) of the AS
UkrSSR at the Starosellskaya Biological Station. This method
is based on the evaluation of the vertical evaporation differ--.
ence determined by means of evaporators dasigno'd by A.A.
Solopko., Comparing the results of both of these mathods the
authors draw the conclusion that the evaporation data ob-
tained by ~he gradient method are more precise an0-i-eliable

PERIODICAL: Pribory i tekhnika eksperimenta., no.2, 1962, 175
TEXT: Because of its transparency over a wide range of the
spectrum, white sapphire is becoming widely used to make windows,
for various light sources. It was noticed that on heating
these windows, there was a fall in'their transparency near to the
short-wave boundary of transmission which was recovered'on
cooling- Measurements-of the transmission of sapphire laminae
as functi.on of temperature.were made on a vacuum monochromator in
the light.of a hydrogen lamp with a window oflithium fluoride-.
Fig.2 shows percentage transmission as function of wavelength in
Angstrom units-for varioug temperatures and Fig.3 shows the-
transmission boundary in A, at the 5% level as function of
tempera:ture. The facts presented should'be allowed'for in
designing instruments with sapphire windows that are liable to
..become hot. There arer 3 figures.

Title- On immunoprophylaxis against distemper
'Periodical Veterinariya, 6, 28-30, June 1954
Abstract The veterinary section of the sc.ientific-technical council of the Ministry of
Agriculture USSR, has recommended the polyvalent embryo-formol-aluminum hydro-
xide vaccine and hyperimmune serum of Y e. S. Cherkasskiy in the treatment and
prophylaxis of distemper. The vaccine was tested in different parts of the
USSR, under various climatic conditions;'it produced dependable immunity in
adult animals, lasting at least-6 months. Distemper was successfully treated
by injection of a double prophylactic dose, 2-3 times. Cherkasskiy originally
obtained the vaccine and serum by inoculating the developing chicken embryo
with the virus taken frompuppies and then inoculating the puppies with the
virus taken from the developing chicken embryo. By means of this cross inoc-
ulation it is possible-to change the nature of virus and to attenuate it.to
the extent that all the virulent properties of the virus become completely
lost. This vaccine has been manufactured since 1950 by the All-Union Scien-
tific-Research,Institute of Commercial Hunting IVNIO.

The diagnostic apparatus UZD-4 designed in the ~9HMMMWvO (VNIIMIiO)
is described. It is noted that one of the most important parametera
of the instrument - the maxim4m depth action - is almost entirely
determined by the ultrasonic damping coefficient in tissues and to
a lesser degree depends on the power of the transmitter, the sen-
sitivity of the receiver and other factors. The VZD-4 works at
frequencies of 2.5; 5; 1Qand 15 Mc/s,a launching frequency of
1000 c/s, and a pulse length of 3 microseconds. The depth of sound-
