the low frequency oscillations and increases the amplitude of the
high-frequency oscillations. The spectrum of the high-frequency
oscillations was plotted with the aid of a moving electric probe,
the output of which was fed to a noise meter. The oscillations had
a maximum in the frequency range 25-50 megacycles# the position and
height of which depended on the beam energy (for a fixed current)
on the magnetic field, and on the pressure in the chamber. It has
also been found that an optimal pressure exists at which the ampli-
tude of the oscillations is the largest, and that i;1A.e optimum value
of the pressure depends on the beam energy. The oscillation fre-
quency depends also on the beam energy and the maximum of the spec-
trum shifts towards higher frequencies with increa 'sing energy. An
increase in the amplitude of the ion oscillations leads to t1te sup-

of the phase velocity by the method of a probing beam which passes
through the main plasma beam and enters an analyzer with a retarding
potential. The plasma tested constituted a hollow electron beam 50
cm long and 2 cm in diameter, with an energy that ranged from 200
to 300 volts at 25--50 milliamperes. The working pressure wits
1.3 x 10- 3__1.3 x 10-4 n/m2 . The probing beam (1 mm. dia, (10--15
gA, and 0--40OV) traveled on the beam axis in the injection direc-
tion. The potential was measured with the aid of an incandescent
probe inserted inside the hollow beam through a break in its annu-
lar section. The experiments with the probing electron beam indicate
the existence in the plasma of considerable oscillations which
modify both the main beam and the plasma. The plasma electrons be-
come accelerated by the high-frequency field of the wave produ':'ed
in the beam-plasma system, and this causes electrons to-escape

ACCESSION NR: AT.4036041
through the ends of the system. The escape of the electrons should
be accompanied by an increase in potential in the space occupied by
the plasma. However, the situation is complicated by the existence
of transverse ion oscillations which cause the ions to move away to
the cylindrical surface of the chamber. it is concluded that the
plasma oscillations cause formation of an uncompensated charge,
the polarity of which depends on whic of the processes predominates,
t)ie drift of the ions due to the low- equency transverse oscilla-
tions or the drift of the electrons due to their interaction with
the longitudinal high-frequency wave. In strong magnetic fields
the ion oscillations are suppressed and the longitudinal high-
frequency oscillations become predominant. It is therefore to be
expected that in a trap in which electrons are injected in suffi-
ciently strong magnetic fields (on the order of (1--2) x 105 'Via),
the plasma will have a positive potential. "The authors are grate-

ABSTRACT: Oscillations of an election bunm in a longitudinal magnetic field of 200
to 300 Oe 'have previously boon observed (V.D.Fodorchonko, V.I.Uuratov, B.N.Rutke-
vich and V.M.Chorny*y,ZhTF,32,958,l962). These oscillations occurred at two widely
differeAt frequencies! approximately 100 kc and from 25 to 50 Ito. The low frequency
oscillations have been ascribed to transvorso motion of reaidual gas lons in the
space charge field of the beam, and tho high frequency oscillations are thought to
be longitudinal plasma oscillations. The present paper reports an investigation of
those phenomena in stronger magnetic Xiolds, up to 3000 Oo. The electron boam was
2 cm in diamet;r, 50 cm long, and carried 25 to 50 mA of 200 to bOO V olectrona.
The pressure in the chamber was varied from 10-5 to 10-6 11g. The OsCillations

were observed by means of a movable probe located near the beam but outside it. As
anticipated, the use of the stronger imignotic field considerably decreased the in-
tensity of the low frequency component and increased that of the high frequency
component. Varying thq magnetio.tiold strength, the residual gaa pressure, ar.4 the
electron beam energy wore found to alter the rather complex spectrum of the high
frequency component. For example, increasing the electron energy from 200 to 300 V
increased the peak frequency from 30 to 47 Me and decreased the peak intensity bya
factor 2.5.It was found that when secondary emission from the boom collector was
-suppressed by an appropriatoly-charged grid, the intensity of the high frequency
oscillations decreased greatly. It is conjectured that secondary emission is so.
how involved as a feedback mechanism in maintaining the oscillations. The presence
of standing waves was established, the plinse velocity being 6 x 108 cm/sec. 'rho
electron beam was velocity modulated by applying a high frequency signal to an ap-
propriato electrode. Signals at both the low and the high-resonant frequencies weref
..amplified. When the low frequency oscillations wore increased in amplitude by moduJ
lating the beam at thoir resonant frequency (approximately 100 kc), the amplitudo
of the high frequency-oscillations correspondingly decreased.

ABSTRACT: Interaction between high and low frequencies of plasma oscillations was in-

relationship beiween~thsse two frequencies and the intensity of the magnetic field.
The theoretical results were tested experimentally using an electron beam (0!0-40 ma)
moving through a gas at pressures in the 10-6 mm lig range. The interaction of the
waves was studied under the condition where the external excitation field: 1) did
not coincide with either electron plasma or electron cyclotron frequency; 2) coincid-
e,d with electron plasma frequency-, and 3) coincided with electron cyclotron frequen-
cy. The Intensities of the'excited blue- and red-shifted satellites were found to

of arcs at 3300 V, at currents between 100 and 1500 A and air gap
width 2 4 6 MM. The influence of the magnetic fieldp magnitudo of
commutation current, supply votage, and inductance of the circuit
on the process of extinguishing are studied in detail. Experimen-
tal characteristics are compared with theoretical ones. An in-
crease of the magnetic field is found to cause a decrease of ener-
gy, dissipated by the are in the process of disconnection; an in-
crease of energy supplied causes an increase of the cooling in-
tensity of the are. The experimental dependencies obtained allow
calculation of nominal breakoff currents and voltage excesses for

It has been shown that the causative factor of 25-stage meningoencephalitis is
a neurotropic virus which resembles that of tick encephalitis. It is six-alar in
its antigenic structure and reactions to the viruses of Western tick encephalitis
and Scotch encephalitis, but can ge distinguished from them by reason of its
different action on white mice. Two-stage meningoencephalitis has nothing in
common with listerellosis.

Ticks of-Byelovezhskaya Pushcha contain neurotropic virus which upon introduction into
the brain of mice or sheep produces disease resembling Scotch encephalorWelitise While
humans in this area get that type disease, it does not affect sheep under natural
conditions. It seems that Ixodes ricinus carries virus which produces disease of the
Scotch typqj (meningoencephalitis), while infection from 1. persulcatus, resUts in cUss-
ical type of tick encephalitis similar to that occurring -in the Far Fast (with a
polimyelitic syndrome). Where both species of ticks occur locally,, buth types of
disease are observed. Perhaps virus is same in both cases., but is modified by species
of tick which carries it.

ABSTRACT: The effect of phosphorous pentoxide on tetrahydrophtalic
anhydrides leads to the formation of aromatic hydrocarbons
with elimination of CO and H 0 as was proved by some of the
authors (referencenl-6). In ihe present paper the influence
of phosphorous pentoxide on phenyltetrchydrophtalic aldehyde
(I) (an addition of phenyl-butadiene with maleic anhydride)
was investigated. In this case the reaction lead to the
formation of fluorene (with a 21% yield) instead of diphenyl
as might have been expected. It seems that the reaction
passes through intermediate stages of an intramolecular

influence of phosphorous pentoxide this is changed into
fluorene. The authors simplified this reaction by starting
from phenyltetrahydrobenzoic acid ( an addition of divinyl
with cinnanic acid (V). When it was warmed up with phosphorous
pentoxide fluorene was formed with a 63% yield. From the
addition of cinnanic acid with isoprene and 2,3-diriethyl-
butadiene 3 methy1fluorene (50% yield) and 2,3-dimethyl-
fluor9ne (53% yield) were produced. The production of just

it, from the addition of ieoprene with cinnanic acid confirms
the structure of this addition as 4-methyl-2-phenyl-1,2,3,6-

with dicyclohexenyl (VIII) and dicyclopentenyl (IX), 1,2

TEXT: Neutral phosphates are well-known compounds used in industry and
agriculture. But so far no phosphates had been synthesized which contain
in the molecule a five-membered cyclic eater grouping, nor high-molecula*--
phosphates that had not been condensed via the vinyl ester groups. In
the present papery a simple process is suggested for the preparation of
ethylene alkyl phosphates and their polymerization. These were
synthesized by oxidation of ethylene alkyl phosphitea with nitrogen
dioxide. The cyclic phosphates synthesized were used by the authors to
nbtain polymers containing phosphorus. They also found that cyclic
phosphates (contrary to phosphonates) form higher-molecular compounds on

ABSTRACT: Methods of determination of Be using morin which forms a
morin lacquer with Be in an alkaline solution, fluorescing with
a characteristic yellow-green color, are given. A 0. _3 - 0. 5 g
test sample is fused in a Pt crucible with 6 - 7 times the amount
of sodium. The melt is treated with 50 cc of hot water and HCI
to a complete decomposition, the solution is evaporated to dry-
ness in a water bath, the residue, for the separation of silicic
acid, is taken twice to dryness with 5 - 6 cc HC1, then moistened
with HC1, 50 cc of hot water is added, and the solution is filter-
ed. The precipitate is calcined in a Pt crucible and treated with
Card 1/2 H?SO4 and HF, the residue is fused with KZSZ07, leac'ned out

with hot water and added to the filtrate left after the separation of the silicic ac.1d
To the combined filtrate NH40H is added (to a weak odor ) for the precipitation
of Be and the sesquioxides. The precipitate is dissolved in 554 H2S04 and the sol-
ution is electrolyzed with a Hg cathode at 4-6 amps and 5-7 volts. After'the com-
plete precipitation of iron the solution is heated to boiling and Be and Al are pre-
cipitated with NH40H. The precipitate is dissolved in 0.25N NaOH solution, and
the solution is diluted to 100cc. To Z5 cc of the solution are added. 2 cc of satu-
rated Na P04 solution and 0.5 cc of 0.02% morin solution (20 mg in 100 cc of ace-
tone). Re mixture is read colorimetrically ir. ultraviolet light, comparing the
intensity of the yellow-green fluorescence with a standard series. The deter-
mination of 0.0001% of Be is feasible with *0.0001% precision. The method is
recommended for the determination of small quantities of Be in minerals and
rocks.

ABSTRACT: Several mineralogical problems associated with a number
of low-temperature deposits of South Fergana are
examined in this article. Special experiments were
conducted to explain the cause of blackening of the

the selenide of K turns black due to its photochemical
decomposition under the ultraviolet rays in the presende
of water vapor, The blackening type.of K d%ffers from

Mineralogy of Low-Temperature Deposits (Cont.)
The author presents actual data which show that under special
conditions some varieties of K can undergo an intensive oxidation.
This fact should be taken into consideration when prospecting for
mercury deposits, It was established from' the study of changes in
limestones in some mercury deposits that blocks which uWlergo a
hydrothermal'. alteration may far exceed in volume the ore bodies
contained in them. These changes consist of lightening of rock
color, the appearance of stains, the increase of jointing and
porosity of limestone, and by the metasomatic replacement of
limestone by other carbonates, Pyrite (P) is seldom found in mono-
metallic mercury deposits, whereas P appears to be a common mineral
in overlaying slates, especially if the latter are of a coal-bearing
type. The author notes an increase in the content of P In the.zone
located above rich ore deposits, and a sharp decrease of P above the
barren sections, A close genetic bond of P with the hydrothermal
process is obvious. As, Sbp Hg, ando to a lesser extentj Cu, Znj
Ag and Au appear to be the characteristic inclusions of this P.
It is possible to isolate the prospective blind ore deposits for
further exploration by studying the elements which are present In
the form of inclusions in P.

PERIODICAL: Geokhimiya, 19589 Nr 39 pp. 273 .. 279 (USSR)
ABSTRACT: This paper deals with the Khaydarkan deposit in -the southern
Fergana valley. Elementary mercury occurs in several districts
of this deposit: Mednaya gora, Glavnoye pole, Promezhutochnoye
pole' Kara-Aroha. The geological conditions of the deposit
are discussed by the aid of diagrams. Analyses of the surround-
ing slates and of.mercury are given in a table. The analyses
were carried out by To To Nukhovaq spectral analyses by
Z. M* Lopott at the Laboratory of the "Bredaztsvotmetrezvedka"
Trust.
For ouch important accumulations of elementary mercury a
hypogenetio formation must be assumed. This appeexs to be con-
firmed by the following facts: 1) The complete lack of traces
Card 113 of leaohing-out in the cinnabar in the adjoining ore bodies.

2) Geological.struoture and posit-ion. The mercury- containing
ore is immediately located upon the richest cinnabar deposits
in the central part of the vault-like folded structure in
the overlapping slates.
3) The surrounding slates. are, to a considerable extent,
uniformly soaked with mercury.
4) The chemical composition of mercury; hypogenetic formation
can be proved by the composition of the impurities.
The author draws.the following conclusions: The results prove
the correctness'o'f the opinion expressed by A. A. Saukov that
mercury can be transported not only by hydrothermal solutions
but also in a gaseous state. The distribution of mercury in
the surrounding rooks may originate either from cinnabar de-
posited from the hy(trothermal residual aolution~-which Qan
serve as microindicator (Ve E. Poyarkov, Ref 4), or else the
mercury is finely distributed in the rook; it can not serve
as an indicator. There are 5 figures, 1 tabled and 7 re-
ferenose, which are Soviet.

ABSTRACT: Geochemical investigations include the study of ore indicators
which tell of the presence of deeply-hidden ore bodies. The
results of investigations carried out on some low-temperature
antimony-mercurj d6D0aJLt8 of the plastic-formation type are
presented. The ore:covering pyrite contains admixzures of
several elements rhich are 44-Irpomorphic of the underlying ore
strata, mainly mercury, antimonyj arsenic and zinc. The beat
results with ore covering pyrite are obtained with blind ore
strata at ore sites already under investigation, where the
usual methods of metallometric investigations are of no avail.
The method doesnot require any large labor force or equipment.

The remains of the old mining sites (subterranean
passages and halls) were found and proofs obtained
that considerable quantities of cinnabar and mer-
