ABSTRACT: The solubility of niobium pentoxide in solutions of
aelenic
acid of various concentrations was investigated at temperatures
of 25, 50, 75, and 1000C. Purest Nb20 5 (99-97%) and selenic
acid (99v8%) were used as initial materials. The results show
that the solubility of Nb 0 rises with the increase of the
2 5
concentration of H2SeO 4* Upon doubling the concentration of
selenio acid the solubility of Nb 205 is increased 29 times
at 250 and 120 times at 1000. In the system Nb 20 5- SeO 3-H20
the solid phase in the concentration range of 14-33 N H2SeO 4

fact was proved by means of the radioactive indicator Co
The roentgenograms of the solid phases confirm the amorphous
character of hydrated niobium pentoxide. Niobium, pentoxide
.gel is hydrated in a 60~ selenic acid solution while a
hydrate
is formed with a composition similar to that of ortho-niobic
acid: H3NbO 4*0-5H2 0. Upon a further concentration increase
of selenic acid this hydrate is dehydrated. There are
1 figure, 3 tables, and 16 references, 7 of which are Soviet.

ABSTRACT; Amperometric titration which is mainly used for
practical
purposes of rapid analyses can also be used for solving
theoretical problems. Two different curves were measured
(Diagram, Fig 1) in the titration of calcium salts. The
first curve is formed with a large KC1 excess and shows
a marked minimum with subsequent increase of the diffusion
current. The second zurveg howevert shows a flat course
after the minimum. The end points of both curves do not
coincide. For precipitating the same quantity of calcium, but
different quantities of ferrocyanide are necessary. Gradua-
Card 1/ 3 tion aurves (Diagram, Fig 2) were plotted for both
curves:

abscissa ml Ca salt, ordinate - ml potassium ferrocyanide,
which corresponded to the end points measured, The recti-
linear course of these graduation curves indicates that the
ratio between calcium and ferrocyanide remains constantibut
is different for each of the two titration curves (Table).
Thus there are two precipitates. The first one corresponds
to the formula CaK,[Fe(CN)"2, the second one to the formula
6J
Ca4K4LFe(CN )6-13* The second compound is little soluble as
may be seen from the constancy of the diffusion current. The
first compound probably forms a new soluble compou d,

again an increase of the diffusion current after 4ttaining
the
end point. Consequently, the stability of the precipitate
formed itay be assumed on account of the course of the diffu-
Elon current after attaining the end point, On the titration
of magnesium salts the diffusion current showed two minima.

mentioned above. There are 2 figures, I table and 4 Soviet

ABSTRACT:
The method of isotopic paleothermometry is based
on th 18

equilibrium distribution of the heavy isotope of oxygen
0

between the oxygen of water and CaCO precipitated from the
3

water. This distribution depends on
the temperature of

precipitation. Many characteristics of the
paleobiology

of fossil organisms (life duration, surrounding
medium, etc)

can be cleared up by making use of temperature
"records" in

carbonates.

The authors elaborated an experimental
temperature scale

which was obtained by settling CaCO out of Ca
(HCO
)

solutions in a thermostat at varioua temperatures. Comparing

with thissaalep several dozens of fossil shells from the

Cretaceous deposits of the Russian plateau and Crimea were

investigated. The most reliable results were obtained from

ABSTRACT- 44 samples of sulfides and sulfates from the Uchaly
deposit
were examined. The S32/s34-ratio was determined with the
mass spectrometer MS-2. Sulfur from the meteorite of
Sikhote-Alintwas used as standard, its isotope ratio
amounting to 22.20. The results and their deviations from
the standard are recorded in a table. The isotope ratios
show considerable deviations which do not depend on the
type of mineral or on the region. This is indicative of
different stages of ore formation. Pyrites of massive
and intersparsed ores show the same isotope ratio and
therefore can be classified into the same stage of forma-

ABSTRACT: In this paper an ion receiver is described which
makes possible
to change the distance of the collector gaps from 7 to 11
mm,
and a simultaneous recording of the mass 28 (C 12016 ) and

tantalum sheet and are screened-off against the falling-in
of secondary electrons. Figure 2 shows the supplementary
device made of glass by means of which both the CO-sample
to be tested, and a CO-standard sample are connected. with
the ion source of the mass spectrograph. In order to
determine
the absolute ratio

TEXTs The symposium took place at the University of nrnningan
(Netherlands)
from September 15 to September 20, 1959. It was attended by
about 50 delegates
from 12 countries. At present, a number of problems of geology,
geochemistry,
oceanology, and archeology is being solved by means of the
radiocarbon method of
dating. In order to be able to compare the results obtained by
various labora-
tories throughout the world, a uniform international standard of
present-day L,
radiocarbon in the form of oxalic acid was recommended. A stock
of this acid is in
the U.S. National Bureau of Standards. For the purpose of
establishing an ordered
system of notation for all research results publishA with
respect to 04, it. was
recommended that each laboratory chose two letters of the
alphabet for its arti-
cles and mentions the number of the sample. The Institut
geokhimi-- '. analitiches-
koy khimii Akademii nauk SSSR (Institute of Geochemistry and
Analytical Chemistry
of the Academy of Sciences of the USSR) decided that from *1960
onward the labora-
T-ory will, for the purpose of determining the age according rct
C14, denote the
samples by "Mo" and the corresponding number.

TEXT: The authors improved the accuracy of mass-spectrometric
determina-
tions by using a three-filament ion source (Fig. 1) in which
it was
possible to heat all three filaments (Fig. 2). Each of these
could be used
as the vaporizer while the other two acted as ionizers. The
ion source had
a alit of 0.1 mm. An M312302 (MV2302) mass spectrometer was
used as
analyzer. A definite amount of sulfide, carbonate, or similar
compound of
the element to be investigated was applied to the vaporizer.
The chemical
compound used was not found to affect the ion yield. In the
course of the
experiment the ion current was determined after applying the
samples to
filaments (1) or (2). Evaporation took place without
ionizationg and ions
were produced by the filaments acting as ionizers. After 15
different
elements had been examined three different groups of elements

ABSTRACT: Three mechanisms of ion formation from solid substances in
the
spark source of a mass spectrometer are discussed. Cathodic
atornization of the
substance with a high frequency impulse spark in vacuum is considered
to be the
principal mechanism of ion excitation; the atomization is due to icn
,.rnpact and
volatilization, but the average electrode surface temperature is no
higher than
500- 700K. Polyatomic molecules are formed, as shown by the presence
of up to
C20 in graphite, Si7 in silicon, and molecules such as Si3C, Si4C,
S'2C2, SiC5,

etc. in silicon carbide. Multicharged ions are formed; in pure
silicon the ratio
of Si+/Si++ is about 10. The one-. two-, and possibly three-charged
ions and
polyatomic molecules are formed differently than ions with higher
charges. The
latter are believed to be formed in the spark channel at plasma
temperatures of
about 40, OOOK. Ions may be formed by thermionic emission of elements
with low
ionization potential which especially true for Li, Na, K and Ca.

ABSTRACT: This is a continuation of work by one of the authors
(Chupaldiin, ZhAkh v.
17, 665, 1962 and v. 18, 1059, 1963, and earlier) dealing with
enhanced emission of
,ions from various substances by using emitters with sorbent
materials. A three-
ribbon thermionic ion source was used to compare the ionizing
ability of three widely
used sorbents in mass spectroscopy, namely.silici
gelnluminum-silica gel, and
zirconium-silica gel. The main purpose of the investigation was
to determine the
mechanism whereby ionization is produced with the aid of
emitters, since the high
efficiency of the emitters seems to contradict the Langmuir-Saha
equation. The in-
dical'.or elements used were lead and zinc, controlled batches of
which were deposited
on sorbents made of nitric acid solutions of their salts. The
evaporator temperature
ranged from 1400 - 17000, depending on the type of sorbent and on
the heater materials
It is concluded that during the heating of the evaporator, an
emitter layer is pro-
duced from the sorbent, and simultaneously the atoms of the
investigated element dif-

fuse into this layer. Me emitter layer consists of oxides which
are normally in-
sulators, and acquire semiconducting properties at high
temperatures, of the barrier-
layer type. The surface of the emitter layer and the surface of
the heater form a
capacitor with high field intensity, thus enhancing the emission
of ions. Various
aspects of the mechanism are described in some detail. This
interpretation does not
contradict the Saba-Langmuir equation. The authors thank

change the conditions
of ion formation in the vacuum spark. Thus, the mechanism of

TITLE: Improving the wear resistance of the cylinder, the
piston
and piston rings. (Povysheniye iznosoustoychivosti

ABSTRACT: For manufacturing wear resistant cylinders and
cylinder
liners low alloy and innoculated cast iron are suitable
materials. Experience relating to non-uniform wear, seizing
and other deficiencies in compreasor equipment produced by
various Soviet Works is discussed and also measures for
overcoming individual shortcomings. In the latter part of
the paper the author deals particularly with the design of
piston rings and the piston configuration, whereby particular
attention is paid to the oil flow and it is mentioned that the
here described design (shown in Figs. 1 to 3) will also reduce
considerably the oil consumption.
There are three figures.
