is suggested. The compounds obtained from aqueous solution deviated in
their composition from the theoretical. composition, probably due to water
dontent. The considerable increase in volume of the Be and Zn compounds
above 2000C is ascribed to continuation of the incomplete chemical reaction
at, elevated temperature. In the esters. of aromatic o-hydroxy acidst
carbonyl oxygen of the carboxyl group effects the formation of the coordi-
nation bond. In o-methoxy acidt the oxygen of the methoxy group has an
effect. All polymers were colored powders. The polymers obtained from
the melt had a composition,which came nearest to theory. There are

TEXT: Generation of high-power bursts of ultrashort-wave
frequencies is of importance in linear accelerators of heavy
particles. A pulsed oscillator based on the triode, type
rv%-i,,,A (GI-4A), was therefore doveloped. Constructionally, the
oscillator is based on coaxial tuned circuits, in which the
tube operates as a grounded-grid system (Ref, I - M.S. Neyman
Triode and totrode generators for URF (Triodnyye i tetrodnyye
generatory SVCh), Sovetskoye radio, 1950). The anode-grid
resonant circuit is in the form of a quarter-wave line,
terminated with the interelectrode capacitance Cag (Fig.. 1).
Since the external diameter D 33 cm, internal diameter
d = 14 cm and Cag = 35 pF, the resonance frequency is 142 Mcls
and the length h of the anode grid-tuned circuit is 19 cm;
Card 1/3
S/142/6i/oo4/oo6/015/017
A high-temperature ....
these calculated data were verified wperitnentlly. The
cathode-grid circuit is in the form of a short-circuited
polycylindrical coaxial section of a half-wave line; this is
terminated with the capacitance Cag . The feedback is provided
by three non-adjustable loops positioned at angles of 1200
with respect to each other, in such a manner that the loops pass
through the conmon wall of the resonators. The separator
condenser in the nnod-grid circuit consists of six groups of
condensers, each consisting of two condensers in series. The
oscillator was tested with an 8`-~ resistive load, which wag
in the form.of a polystyrol cylinder with a water solution of
sodium ca2-bonate. It was,possible to obtain a maximum power
of 1.2 MW with an anode voltage of 32 kV and pulse duration of
450 lis. The oscillator was also tested with a higli-Q load
formed by the resonator of a linear proton accelerator; this
had a resonance frequency of 142 Mc/s and a quality factor of
50000. It was found that at an anode voltage of 36 RV the
resonator of the accelerator received a power of the order of
500 W, so that the protons could be accelerated up to energies

ABSTRACT: The interaction of tungsten-6-chloride with iron pentacarbonyl
in an ethyl ether medium was investigated. The tests in the
autoclave were carried out at the following molar ratics of
the individual components: W01 6 : Fe(CO)5 - I - 2,25 ari
1 : 3.25. The temperatures during the tests were: 70, 90, 110,
130, 1509 170 and 1900. At the molar ratio Fe(CO) : WC!
1 5 6
- 3.25 : I the yield of W(CO) 6 increases with temperature;
it shows an increase of 29-31% at 200, Gf 34-42% at 700 ' and

Pre,pa=ekoic#n, of tungsten Carbony-1 by the Interaotion of Iron Pentacarb!5nyl
With Tungsten flexaohloride
following equation: WC1 6 + 3Fe(CO)5--*-W (CO)6 + 3Fe C12 4 9CO'
The supply of hydroE~en te "he reaction mixture after the
conclusion of the reaction, inrreases the W (CO4 yield to
85%. This reaction corresponds to the following equation.
WC16 + 2Fe(CO)5 + H 2--O-W (CO)6 + 2Fe C12 + 2HCl + 4CO.
The production of tungsten hexacarbonyl is described ir. detail.
Results which are woll reproducible are obtained by this
method. There are 2 tablea and 7 references, 3 of which are

PERIODICAL: Zhurnal neorganicheskoy khimii, 1958, Vol 3, Nr 11, pp 2433-2436
(USSR)
ABSTRACT: In the present paper the authors investigated the reaction
velocity, the impurities, the time, as well as the temperature
and the pressure of the reaction gases, and the nature of the
solvents on the course of the synthesis and the yield of the
carbonyl compounds of inolybdenum and tungsten. The synthesis
of molybdenum carbonyl lasted 2-3 hourst the synthesis of
tungsten carbonyl 1-1,5 hours. Tungsten carbonyl is produced
with a yield of 81-85% at a reaction temperature of 32-670. The
production of the carbonyl oompounds of tungsten and molybdenum
is usually carried out at 50 atmospheres absolute pressure.
Experiments were carried out to produce molybdenum carbonyl
under a pressure of 20-30 atmospheres excess CO-pressure. Zinc
Card 1/2 powder and aluminum powder were used as reducing agents. If
SOV/78-3-11-1/23
The Production of the Carbonyl Compounds of Molybdenum and Tungsten
aluminum is used as reducing agent the yield of molybdenum
carbonyl amounts to 0,6% at 180C, 10% at 1000C, 9% at 1500C
and 100 atmospheres excess pressure. If iron powder is used
as reducing agent, the yfeld of molybdenum carbonyl amounts to
1,5% at 1000C. If zinc ia used as reducing agent, the yield of
molybdenum carbonyl is not higher than 616%. Mainly zinc powder
is used as reducing agen-, for the production of tungsten carbonyl.
The yield amounts to 85%- It was shown that for the production
of carbonyl compounds ether in a quantity of not more than
2 g-mol to 1 g-mol metal chloride is necessa-ry.

ABSTRACT: It has been found that molybdenum hexacarbonyl is formed in a
maximum yield of 28-5% by the interaction between iron penta-
carbonyl and molybdenum pentachloride in the presence of
hydrogen chloride un&ar a carbon monoxide pressure in an ether
medium. Molybdenum hexacarbonyl is formed in a 15% yield at
1750 in the presence of compressed hydrogen in an ethyl ether
medium. Molybdenum cerbonyl is formed in a yield of 23.4% at
1750 when the reaction is performed in an autoclave with
hydrogen (initial pressure 100 atmospheres) and carbon monoxide
(initial pressure 50 atmospheres). There are 2 tables and
1 Sovietreference.

TITLE: Synthesis of triethoxy silane,
PERIODICAL: Plasticheskiye massy, no. 12, 1962, 28-29
TEXT: Triethoxy silane is synthesized by bringing trichlorosilane into
reaction with ethanol at 25-300C without using a solvent. The following
conditions must be satisfied: (i) In the reactions the component ratio
must be strictly adhered to. . The volume ratid'inlicat6d Is: SiHCl 3:C2H5 OH-1 :1-75-
(2) The water content of the ethanol must.be'leas than 0.2~. (3) The
hydrogen chloride formed must be evacuated rapidly from the reaction
vessel. This wao secured by passing through nitrogen at a rate of
1-1,5 l/min per liter of reacting liquid, by increasing the nitrogen rate
to -4 l/min when the introduction of .,omponents was completed, and by
heating to 50 OC when the C1 content of the reaction mixture had reached
7%. The flow of nitrogen was stopped -vhen the C1 content dropped below

TITLE: Film-type apparatus ior the continuous triethoxysilane synthesis
PMIODICAL: Byulleten' tekhniko-ekonomicheskoy informatsii, no. 9, 1962, 21 - 2j
MT: This new apparatus~'for Ithe continuous triethoxysilane synthesis, in
which the reiction and desorption zones are separated, has been developed by an
organization of the Gosudarstvenny komitet po khimii (state committee on Chemistry)
at the Council of Ministers of the USSR. The apparatus is a film-type mass-ex-
c1tinge column, whose design and operation are described. A table gives compara-
tive data on the triethoxysilane synthesis in film:-type and bubbler apparatus.
The raw material consumption in the former is only half of the latter, while the
output of the film-type apparatus is'by 25% higher than' that of the bubbler type.
Comparing the technical and design data of the continuous film-type apparatus
with thoze of the periodic bubbler apparatus, it is shown that the working volume
and hydraulic resistance of the film-type apparatus are considerably lower than

TITLEt Carbonyl iron powders
PERIODICAL: Akademiya nauk SSSR. Izvestiya. Seriya fizicheskaya, v. 25,
no. 12, 1961, 1483 - 1486
TEXTs Basing on certain relationshipt established between the physica-
chemical and the electromagnetic properties of carbonyl iron powders,
the authors have developed new types of powderst Carbonyl iron powders
(KZh) exhibiting small values of the loss factor (Ref. 3: Otchet
organizatsii P/ya 4019, 1959), carbonil-iron-nickel powders with different
nickel conte'nIs (Ref. 43 Volkov, V. L. Ivashova, M. V., Tolmasskiy, I. S.,
Otchet organizatsii p/ya 4019, 1958) 3nd decarbonized carbonyl iron
Bj(X'VKZh). The examination of the above-mentioned powders has shown
that ihe initial permeability of a KZh-type powder is much smaller than
that of powders of the types VKZh, H -5(N-5) and H-50(N-50). This is
due to the fact that KZh powders contain considerable carbon and nitrogen

admixtures (in the form of carbide and ferronitride), and to the nodular
structure which prevents the domain boundaries to be displaced under
magnetic field action. Magnetic losses increase by decarbonizing carbonyl
iron powder. Due to the destruction of the nodular structure, eddy current
losses, e. g. occurring in VKZh powders are almost five times and hyster-
esis losses twelve times those of the corresponding losses of KZh powder5.
Due to lower conductivity, resulting from the iron being alloyed with
nickel, losses of carbonyl iron nickel powders (particularly of the N-50)
are much smaller than those of VKZh. Compared with KZh powders, decarbo-
nized powders are characterized by hieher temperature coefficients of the
initial permeability, because with the! admixtures removed the boundaries
of the domain are supposed to be displaced easier. Electromagnetic para-
meters are chiefly determined by their chemical composition and their
particle size. It has been shown that hysteresis losses are minimized by
reducing the carbon and nitrogen content. Due to a smaller number of
particles exhibiting nodular structure, a further removal of admixtures
results in an increase in the eddy current and hysteresis losses. A
decrease of admixtures in KZh powders as the result of different conditions

of preparation decreases the temperature coefficient of the initial per-
meability. An increase in size of t'ne particles of Uh powders, the
chemical composition remaining unchanged, leads to an increase in hyster-
esis and eddy current losses and of the temperature coefficient of initial
permeability. The frequency dependence of the magnetic loss angle tangent
found in this ws.7,~apparently confirms the presence of magnetic viscosi-
ty in carbonyl iron, due to admixtures. There are 2 figures, 3 tables,

ABSTRACTs An amplifier circuit'is suggested :Ln which AGC depends on the d-c
-~component of the emitter current and on the nonlinearity of transistor characteris-
,,.;ties. Accordingly, the AGC resistor, in a common-emitter or common-base circuit,
-i
,)is shunted by a capacitor which passes the r-f component and impede3 the slow-
varying component of the.emitter current. Ap,,proximate formulas are developed for
il designing such an amplifier. They were verif led experimentally ---on a P41 1-transistor
amplifier operating at a resonance frequency of 26 Me with 3Mc and an
equivalent circuit resistance of I kohm. The new method is Int'Wed for analytical,

ABSTRACT: The author discusses typical transient process features
in video amplifiers with 1ogarithmi-c-amplitude charac-
teristics (LAKh - logarifmicheskaya amplitudnaya kharak-
teristika), which is obtained by shunting the anode
loads of amplifier staE;es by nonlinear elements, i.e.
vacuum tubes or semiconductor diodes, for example DG--
Ts, D2 or D9 germanium diodes,, Relationsh~ps are derived
for the pulse setup time at the amplifier output. Values
are given for the inclJne of the flat pulse top and
the "parazitnyy obratr*-y vybros" (translation unknown).
The latter restricts the practical application.of lo--

than 50-55 db. It is difficult to produce a logarithmic
amplitude characteristics in a single stage for a range
of more than 15-20 db. However, it may be obtained over
a very wide range when -.ising several nonlinear stages,
working alternately in logarithmic operation during in-
put voltage increases, Figure 2 shows the amplitude
characteristics of a nonlinear stage, requiring n
stages for alternate op3ration and for two logarithmic
bases (N = 2~72, N = 10). The equivalent circuit dia-
gtam of a nonlinear amplifier stage is shown in Figure
i, The author divides this circuit diagram into two .
equivalent circuit diagrams, shown in Figures 3 and 6,
for the higher and lowe.- frequencies. This is necessary,
since the ptilse front d;-stortion is caused by the fre-
quency response of nonlJ.near stage in the region of the

top are caused ")y the 'lower frequencies. Calculations
and experiments perforried by the author showed that
the equivalent circuit diagram in Figure 6 may be re-
garded as linear, since the current in the circuit
and the resistance of the nonlinear element remain
'practically constant during the influence of pulses
of 5 10 microseconds duration (R - 1 kilohm, C
a 1~ c
0.1 0.05 microferad). The author examines the for-
mation of the "parazitnyy obratnyy vybros" during the
discharge of the capacitor C after the pulse action
is over. The discharge of ca?acitor C is shown by
the equivalent circuit diagram in FigSre 7. The "Para-
zitnyy obratnyy vybros", formed in a nonlinear stage,
is considerably smaller than the signal and is ampli-
fied according to a linear law, while the signal is

periments showed that the relative "parazi.tnyy obratnyy

thmic rangs- of 70 db at the output of a video amplit.-
fier consisting of nonlinear stages whose equivalent
circuit diagram is shown in Figure 1. The pulse setup
time at the outlet of an n-stage logarithmic video am-
plifier decreases considerably with rising input vol-
tages, while the incline of the flat pulse top and the
"parazitnyy obra.tnyy vybros" increase significantly.
The latter are diminished greatly, if the nonlinear
elements shunting the stage's anode load are connected
before the capacitors C 0. All theoretical assumptions
explained in this paper were checked experimentally.

TITLE: Amplifier With an Exponential Amplitude Characteristic
PERIODICAL: Izvestiya vysshikh uchebnykh zavedeniy,
Rad�otekhnika, 1960, Vol. 3, No. 4, pp. 485-492
TEXT: A receiver with a logarithmic amplitude characteristic
has an increased noise immunity in comparison with a receiver
having a linear amplitude characteristic. Usually, the
intermediate frequency amplifier in a receiver has a logarithmic
characteristic which can be exprossed as z = a In x + I -
where x and z represent the input and output voltages of
the amplifier and a is a constant characterising the slope
of the logarithmic amplitude characteristic. However, the
receiver of this type results in a deterioration of the
signal-to-noise ratio at the output, as compared with a linear
receiver. This deficiency can be overcome, if the logarithmic
receiver is followed by an amplifier having-an exponential
amplitude characteristic. In practice, such an amplifier can
easily be constructed. A block diagram of such a device is
shown in Fig. 1 and its amplitude characteristic is illustrated

in Fig. 2. The amplifier can be connected after the detector.
A detailed circuit diagram of the amplifier is shown in
Fig. 6. where the resistances R 1 and R 2 are employed to
produce a suitable bias voltage across the non-linear element
(rectifier). Amplitude characteristics of this device are
shown in Fig* 7. The problem was also investigated experi-
mentally and the results are illu*trated in Fig. 8. where the
exponential characteristics are plotted in a semilogarithmic
scale; the "solid" curves represent the ideal exponentials,
while the dotted curves give the experimental results. An
amplifier with an exponential amplitude characteristic is
particularly useful if the receiver is employed in the
measureinent or detection ofNery weak signals. One of the
disadvantages of the amplifier is its temperature dependence,
which is due to the poor temperature characteristics of the
