of vibration-resistance building-up a number of exhibits is displayed. The VAHX-6
(UANZh-6) machine is used for the repair of tractor parts; the diameter of parts
to be built-up is 15-300 mm for external surfaces; 50-250 mm for internal 3urfaceg
the built-up layer is 0.2 - 4 mm thick; building-up speed is 0.3 - 2.5 m/minj
electrode wire diameter is 1.1 - 1.9 mml electrode oscillation frequenc -t.100 osq/
sec; the electrode vibrates from an electro-magnetic vibrator. The AH,739- _1
(ANREF-1) type head is intended for automatic submerged vibration-resistance build-
ing-up with an oscillating electrode, of shafta, slot connections and planes by
applying 0.5 - 3 mm thick metal layers. The VMA-5M WMI-5M) automatic machine
Is intended for vibration-projection building-up of 0.'5 - 3 mm thick metal layers
in one pass, and for welding thin-walled parts of 0.5 mm thickness and more, in
various media. 'The design of the machine is based on a new principle of performing
circular movements of the electrode tip at a fixed nozzle, a dynamical regulator
of electrode feed rate is used. The machine can be used to build up external
cylindrical and shaped surfaces of over 20 mm in diameter. The electrode feed rate
is o.4 - 1.6 m/min. The machine is mounted on a lathe support with a center height
of 200 mm and more, the longitudinal feed is 1.5 - 5 mm per one revolution of the

is 27.8 kg. The 6r -4 (VG-4) head was developed for the automatic vibration-
resiatance hardfaoing of carbon and high-alloy steels In shielding gas; the head
consists of feed, vibration and electrode adjustment mechanism. There is a epecial
vibration mechanism: when switching on the motor, an eccentrically located bearing
forces the electrode to carry out transverse oscillations in its middle sect'-on,
The wire end oscillates at a frequency of 47.5 periods per sezond, preventing
shaking of the head and ensuring the high constancy of the set-up and a stable
building-up process at extended continuous operation periods. The head produces
high-quality building-up In carbon dioxide of carbon, high-alloy, stainless and
high-speed cutting steels. Some other hardfacing methods are also demonstrated,
such as hardfacing In carbon dioxide of the internal surfaces of over 150 mm dia-
meter press bushings not over I m length, for hot pressing of metals from 4XHb
(4KhNV) steel. There is an electric driven electrode feed, and rotatlon meohanism.
Building-vp on the internal surface of the bushing Is made along a helical line
due to the rotary motion of the bushing and the straight-lined displacement of the
welding head. Building-up conditions are: 200 - 300 amps d-c of reverse polarity,
20 - 36 v arc voltage; 20 - 35 m/hr welding speed; gas cons-4impti-on - 500 to 6co
liter/hr.; electrode displacement from th6 vertex - -00 - 30 mm; bulldlng-up pac!e

ABSTRACT: The currents in the equatorial region of the Atlantic Ocean, and particu-
larly the Lomonosov Current, were studied and the results are reported. Regions of
high salinities, with values greater than 37.25%, are located to the north and South
of the equator in the regions of anticyclones, where water is subjected to prolonged
evaporation. This water moves to the -west equatorial region, where, caning under the
influence of the trade winds, it is speeded up and overlain by a layer of low-salini-
ty water. Water from the North Atlantic anticyclone region moves to the west as the
Antilles Current, which forms two branches: the left branch swings toward the equa-
tor while the right branch moves westward to form the north branch of the Caribbean

Current. Water from the Caribbean Current and Antilles Current forms the warm., sa-
line Gulf Stream. Surface waters at the shores of Africa are driven away toward the
west by trade winds, necessitating inflow of water to balance outflow. This inflow
comes from upwelling, from the Canary Current, and from advection to the east of wa-
ter of anticyclone region origin. This saline and dense water moves east under the
Surface, in a layer 400-500 m thick, as the high-speed Lomonosov Current. Calcula-
tions of transport can be made from speed and direction measurements. From the,
South Atlantic anticyclone region, water of increased salinit-y moves north as the
Guiana Current. At 70 S, on the shores of Brazil, the transport is 33#106 M3/sec. The;
water gradually sinks below the surface and forms with northern water, the Carib-
-10 'I/sac; the decrease of 7-10 m3/se
bean Current. At 450 W the transport is 26 6 m C
can be attributed to an eastward branch at 40 S. This branch forms part of the
with a transport of 0-106 n3/sec
south branch of the equatorial coun 2 at
33 OW. At 2-50 11, 450 W, water of the North Atlantic anticycione region 'Origin is
found moving eastward under a thin layer of wentward-moving trade currents. The
transport of this powerful current Is 54-106 m3/sec. From it, one branch continue-s
cast as -the inter- trade wind equatorial countercurrent with a transport of 15.106
M3/sec; the otherbranch moves southeast reaches the equator, and forms the Lomono-
I
Sov Current with a transport of 39-106 m /sec. This current may be traced east to
Guiana Bay, where the transport is 37-10r' M3/Sec
. At the northeast shore of South
America, currents from the north and south form a field of deformation. In this re-
gion, there is an-increase in tension, causing an increase in acceleration to the

TITLE: The Travelling-wave Tube as a Phase-modulator for
Radio-interferometers
PERIODICAL: Izvestiya vyssftikh uchebnykh zavedeniy,
Radiofizika, 196o, Vol. 3, No. 6, pp. 943 - 946
TEXT: The tube is to be used in the ceritimetre or decimetre
range. The phase change produced depends mainly on the
electrode potentials and the focusing, field, with a change of'
grid voltage producing the most effect. if the optimum voltage
of the latter (U 0) is changed by 1%. the phase change is
40-55%. For changes in U 0 (the synchronising voltage) > 2~g
the corresponding phase change does not increase linearly.
To obtain 10p modulation, one can have a constant phase 0
change of 90 together with a supplementary change of +- 90
between the two interferometer arms. A block diagram of the
interferometer is given. Either one or two travelling-wave
tubes can be used. The block diagram is given of an experimental

set-up (phase-modulator) which was tested in the laboratory.
The dependence of the low-frequency amplifier output of this
phase-modulator on the modulating voltage is shown in Fig. 4.
A travelling-wave tube can also be used as an amplitude-
modulator in a Bingle-antonna radio telescope but it is less
effective in this case. Phase-modulation produces amplitude-
modulation of the internal noise of the tube. In most tubes
the minimum noise factor occurs slightly below the synchronising,
voltage. ii'ig. 6 shows the variation of amplification
coefficient with grid voltage. This curve, and the corresponding
one for the noise factor, are almost symmetrical about the
synchronising voltage U 0 * The dependence of amplitude-
modulation on the frequency of the modulating voltage and its
harmonics has been investigated experimentally. The following
values were obtained for the power of the parasitic amplitude-
modulation harmonics (in % of the total power): 2, 91, 0
and 7 for the fundai..ental wave; second, third and fourth
harmonics, rc-specti-jely. Thus, if a narrow-band filter

centred on the modulatiori frequency is used, only 21,, of the
modulation noise urill be passed. This refers to the case
where only one tube is used; if two tubes with modulation
of opposite phases are employed, the parasitic effects can'be
lowered by an order of magnitude. The advantages of these
tubes are: 1) when the tube is used as a low-frequency
amplifier, there is no need for a special modulator;
2) the range of possible modulation frequencies is increased
by many tens of megacycles. Acknowledgments are expressed to

PERIODICAL: Zhurnal neorganicheskoy khimiio 1959, Vol 4, Nr 10,
pp 2192-2195 (USSR)
ABSTRACT: Beryllium fluoride was produced according to the method of
A. Vo Novoselova, from beryllium sulfate. The vapor pressure
was measured by means of effusion in vacuum and determination
of the weight lost during the experiment (Method 1) or by
analysis of the resultant condensate (Method 2). The effusion
chamber in method
was made of tantalum (Fig 1) and was heated
.1
by a "Mars"-elect c furnace with a power of 1200 w, the
temperature was checked thermoelectrically by means of the
PPTN-1. potentiometer. In method 2 the effusion chamber consisted
of molybdenum* The condensate was analyzed with the colori-
metric photometer of tho FEK-52 type by using the reagent
"Berillon-11 IRYWI. Both methods gave values in good agreement
which are given in table 1. By means of the values obtained

Akademii nauk SSSR (Institute of Combustible Minerals Of the
Aoademy of Sciences, USSR) for the thermodynamic potentials
of the gaseous and solid beryllium fluoride the heat of subli-
mation was calculated to be 55.2~+0.6 kcal/mole at OOK, which
is also given in table 1. Table 2 compares this value with the
data obtained by K. A. Sense et al (Ref 1 ) and the value com-
puted on the basis of the 3rd law of thermodynamics. There are
2 figures, 2 tables, and 1 reference.~
