ABSTRAM In the range of the Sikhote-Alin' geosyncline, no
paleontologioally characterized deposits of the Riddle Paleozoic
have hitherto become known though they had been assumed there.
The 2nd author found, in 1958, remains of trilobites; Calymene
ex gr. blumenbachi Brongn. and Cal. sp. (determinations by
Z. A. Maksimova) in the Rayon of Grodekovoo Besides, she found
there Pelecypoda of the genera Aviculopectae and Pseudomonotis
(determinations by V.M. Kulikov). These organic residues were
found in tuffites, higher up than the 1st intermediate layer of
aleurolites and loamy slate. In spite of an unsatisfactory state
of preservation, the generic determination of the trilobites
should be correct (Pig 1). This figure also shows related forms

ABSTRACT: The active material which is employed in the preparation
of pressed film-type cathode should have the following charac-
teristicB: capacity to produce the necessary quantity of the
activator during its interaction with the reducing agent; good
stability under normal atmospheric conditions; a low gas-
absorption capacity and a low eiaporation rate. The above
requirements are, to a large extent, ft.1filled by barium
tungstate, Ba 3W06- This substance can be prepared from pure
barium carbonate and tungsten oxides the chemical reaction
being in the form:
3BaCO3 + WO3 a Ba 3W06 + 3002
Cardl/? roperties of the cathode can be further improved by using

Pressed Cathode Based on Barium-calcium Tangstate 109-3-3/23
barium-calcium tungstate instead of Ba3W06# This can be
obtained by adding into the mixture of barium carbonate and
tungsten oxide an appropriate quantity of calcium carbonate.
The reactions are then in the form represented by Eqs. (2),
(3) and (4). The resulting material was used in two types of
pressed, experimental cathodes (see Fig6 2a and 6). The
cathodes were in the form of molybdeni=_ cylinders; the active
mixture consisted of 90% tungsten, 9.5% tungstate and 0.5%
aluminium. (by weight). The cathodes were mounted in special
diodes (see Fig.3) which were fitted with special cooling
copper anodes. The distance between the cathodes and the
an des was 0.4 to 0.6 mm. The experimental results are shown
in Figs. 4, 51 6 and 7. Fig. 4 shows voltage current charac-
teristics of the diodes taken at various cathode temperatures;
the two curves of Fig. 4a were taken under pulse conditions,
while the curves of Fig. 46 were measured under static conditions.
Fig- 5 shows the static emission current of a tube as a function
of time; Curve 1 refers to the cathode made of barium tungstate,
while Curve 2 illustrates the emission of a barium-calcium
tungstate cathode. Fig. 6 illustrates the influence of
Oard2/3 hydroSen-poisoning on barium-calcium tungstate cathodes (full

curves illustrate the poisoning effect, while 'dotted' C..rles
illustrate the process of the reactivation of the cathode).
Secondary electron emission of the cathodes was also inves~i-
gated at temperatures of 800, 900, 1 000, 1 100 and 1 200 C
and the resulting curves are shown in Fig.?. From the data
obtained, it is concluded that the barium-calcium tungstate 2
cathodes can produce stable emission densitiSs of 6 to 7 A/cm
at operating temperatures of 1 130 to 1 150 C; the cathodet,
have a life of about 1 000 hours, provided the anodes of the
tubes are properly cooled.

oxide cathodes fail in the acception o' e...ission currents of

ductio-. of barium combinations into the pores of the latter,

str~.ctiori of jpre~-ed cathode It i-: a molybdenum cylinder, in-
to which a mixture of tne active substance, tungsten powder and

temT)erature of the cathode, the interaction of the com-
ponents of tnio mixture leads to the formation of
free barium and to the activation of the cathode. As the
barium compounds tested so far had proved unsatisfactory
(reference 3,4), the authors set themselves the task of test-
ing the compounds resulting from the interaction of alka-
line earth metal oxides of barium and calcium rith acidity-
-and amphoteric oxides. The investigations yielded the
following conclusions: 1. The pressed cathodes mentioned
in t'-le title permit an unirterrupted emission up to a
current density of 8 A cm" 2 if the time of operation
excee's looo hours. 2, The mechanical and electrical
stability of the cathodes is satisfactory, they are
easily enough reactivated after the poisoning. 3. Their
production is simpler than that of the L-cathodes.
4,, The emiosion properties and the life of the cathodes
depends on the properties of the active substance. Here
Card 213 Barium-calcium tunj~state is superior to aluminates because

of Its stability in air. 5. The tungstate mentioned last
makes possible a longer time of operation than the barium
tungstats. 6. P-meliminary tests have shown that the
influence of considerable changes in the concentration
of tungstate in the emitter on the emission currents of
the cathodes is insignificant. A final interpretation
of this phenomenonhas not been given yet. S. D. Uman,

ABSTRACT: There is no concrete opinion existing on the proUem mention-
ed above; thus the data by Khottell and Gausorn (Ref 1), Cham-
berlin and Rose (Ref 2) and Barr (Ref 3) were contradicting
and no systematic investigations had been carried out. The
present work has this aim, the previous experiments having been
mentioned earlier. From the experimental part can be seen
that mainly burners with glass tubes were used and that as com-
bustion gases carbon monoxide, hydrogen, acetylene, ethylene
and hydrogen sulfide, as well as ethanol, ether, acetone,
kerosene and gasoline were used, The pictures were taken on
a rotating film drum, and the Tepler IAB-451 apparatus
was. used . From the experiwental results can be seen
~i-LL at a certain "critical Trelooity" of the fuel the flame
looses its stability, with a difference being made between
Card 1/3 a linear and a volume velocity. In the case of ethylene the

author could especially clearly observe a soot formation at
the surpassing of the laminary velocity of the unsteadyflamei
this soot formation pointed at a decrease of the combustion
density. It was found that the critical velocity and the forn6-
ation of the unsteady flame depend on the nature of the fuel
and that a minimum diameter of the )iurner exists below which
the flame remains steady at any Y61ocity (for CO for instance)
about 3 mm). The flame had two combustion zones -the inner
kinetic one, and the outer diffuse one, the fluctuatiom only
occurring in the outer one, It was observed that the material
of the burner also has an influence on the critical velocity,
just as well as the position of the burner, as was observed
by N~ N, Norkin (Ref 7),, The frequency of flame fluctuations
as well as the form of the flame and its height were also
investigated. In evaluating the results the author mentions
the work by Lewis and Elbe (Ref 8) and it is commented on to-
gether with the two works mentioned in the beginning, on
which occasion it is assumed that the formation of "vortexes"
in the flame is to be explained by an unequal separation of
Card 2/3 the reaction products in the combustion at equal velocity of

escape. Explanations are mentioned for the combustion process,
as well as a computation of the diffusion coefficient of
oxygen; from a table can be seen that the value of the dif-
fusion time is close to that of the fluctuation period of
the flame, from which fact the author concludes that in the
diffiioion oombustion the diffusion coefficient of oxygen and
of the fuel into the combustion products is decisive, and not
that of the oxygen into the fuel. There are 6 figures, 5 ta -
bles, and 11 references, 8 of which are Soviet.

TEXT: The phenomenon of "hairline cracking" and the resulting structural
changes are the topic of this publication. An amorphous, transparent film
made of Lavsan (polyethylene terephthalat&)', 0.15 to 0.40 mm thick, was
investigated. To prepare crystalline samples, the amorphous film was
heated to 1200C for 2 hr, which causes the film to be3ome opaque. Tensile
tests were performed with an PMA-60 (RMI-60) machine at stretching rates
of 100, 200, 500, and 1000 alp/min and constant temperature (0 - 1000C).
The X-ray pictures were taken'with a YPC-55 ~URS-55) apparatus (copper
anode and nickel filter); the anodevoltage was 35 kv, the amperage 20 ma.
The structure of hairline cracks was studied' using an tA~A-6 'MBI-6,

microscope. The density of the samples was de-ermined by the flotation

technique. The formation of hairline cracks was found to occur in
amorphous and crystalline polyethylene terephthalate, low-density poly-
ethylene, polypropylene, caprone, and enant, which, excppt for the first,
were all crystalline before deformation, which shows that hairline
cracking is possible under conditions 3f high-rate cold drawing. Fig. 1
shows that stress curves are the same with formation of a transparent
bottleneck and of hairline cracks. The stress which causes the formation
of hairline cracks is, however, smaller than the one which yields a trans-
parent substance. The structure of hairline cracks in amorphous and
crystalline Lavsan is somewhat different. The opacity of samples decreases
with increasing temperature at constant stretching rate. The sample re-
mains completely transparent when deformed at a definite temperature. The
higher the deformation rate, the higher are the initial teLiperatures of
stretching without formation of hairline cracks, and vice versa. The
formation of hairline cracks occurs below the vitrification point and in
the center of the Lavsan sample with only a thin top layer remaining trans-
parent. The density of samples of oriented Lavsan with cracks (about 0.82
- 1.13 9/cm3) strongly differs from that of the same 3amples showing no
hairline cracks (about 1.52 g//cm3' and drops with ris,_ng temperature and

drawing rate. The orientation of the amorphous Lavsan film with hairline
cracking leads to the phase transition of the oriented film. This was
confirmed by the appearance of new symmetry elements in the X-ray
pictures. When the samples showing hairline cracks are heated to 2000C
for 5 hr, the bending strength in the direction of drawing, but not per-
pendicular to this direction, is considerably reduced. The number of
hairline cracks is somewhat reduced by stDrage in a mixture of phenol and
tricresol at 20OC; pressures of 150 atm lead to an increase in trans-
parency with density increasing from 1.01 to 1.56. The formation of a
bottleneck with hairline cracks in forced elastic deformation of amorphous
polyethylene terephthalate at room temperature is accompanied by a phase
transition, while only the degree of orientaz;ion increases when hairline
cracks form in high-rate uniaxial deformation of.crystalline low-pressure
polyethylene, polypropylene, enant, and/capronej 'When the stretching rate
of Lavsan is reduced below about 200 mm. min, no further hairline cracking
is found at room temperature. The dependence of hairline cracking on
the regular structure of the molecule in a polymer is proved by the fact
that no hairline cracks form in high-pressure polyethylene. V. A. Kargin
