Tz; the laboratory, 400,000 at are reached in work
on!solllds, 1.00,000 at in work on liquids, and
20,000 at in work on gases. Superhigh pressures
abAnge the chem, reactivity of substances. In
chemistry, ;he 05,000-50,000 at range (combined
vith high temps) la particularly important, in
P"Les the 100,000 at range. At 25,000 at, many
brrittle materials (beryllium, steel, superhard
&1loys based on woltram carbide) become plastic.
At 10,000 at, marble can be stretched to 4 times
its 'Length and has a tensile strength 20 times of
that at I at. High pressures can be measured up
to 30,000 at electrically with a manganin resist-
&me gauge. X-ray investigations of AgI, RbI, etc.,
in the range up to 5,000 under use of photographic
films were carried cut in a chamber equipped with
&~Be window. At higher pressures (Ce up to 15,000
at), a Be chamber was used. Recently, for still
hlj~er pressures (AgBr up to 231000 at), din n4
chazzbers were constructed. Compressibility of

Title Production or Superhigh Pressures In a Setup Employing a Conical Piston
Orig Pub Zh. tdkhn. fiziki, 1956, 26, No 4, 874-877
Abstract To eliminate packing gaskets, which are the weak point in 3uper-high pres-
sure setups, a compression chamber was developed vith a conical piston. The
conical piston is pressed into a carefully ground socket and notmal pressure
is produced 6n the periphery of the cone. The cone angle is chosen to make
this pressure always greater than the pressure produced by the piston in the
liguid, thereby insuring hermeticity. The construction is described and
the design calculations (employing the theory of elasticity) are ffiven for
the first version of such a setup. A pressure up to 14,000 kg/cm. was ob-
tained,the pressures being measured with a manganin ri-nometer.

TITLE Some Inves;igations on the Hydrodynamics of a Jet of Liquid
ejected from a Nozzle under the Pressure of up to 1500 atm.
PERIODICAL iurn.techn.fis, 26, fasc.11, 2570-2577 (1956)
Issued: 12 / 19-57
By the work carried out in the laboratory for the physics of extremely high
pressure of the USSR Academy of Science concerning the construction of com-
pressors for extremely high pressures it was possible to develop a continu-
oualy operating machine which is able to eject water through a nozzle of from
0,2 to 0,6 mm diameter at pressures (prevailing before the nozzle) of up to
1500 atm. As such a pressure drop before and behind the nozzle requires great
efficiency of the hydraulic compressor, it was necessary to build a machine
that performed at least 1000 revolutions per minute and that was able at pres-
sures of up to 2000 atm to produce one ton of water per hour.
The authors carried out their tests at pressures below 1500 atm in order to
diminish the part played by the boundary layer introducing the jet of liquid.
They used nozzles of at least 0,45 mm diameter; shape and surface of the noz-
zle exercise considerable influence on the disintegration of the jet of' liquid.
The most favorable shape of the nozzle is shown in form of a drawing. On this
occasion it was not possible to use any of the existing methods for the direct
measuring of the jet velocity, and it was necessary to use the BERNOULLI

equation for this purpose. A diagram illustrates the dependence ~)f jet 7eloc-
ity on the pressure prevailing in the receiver before the nozzle. The authors
computed this dependence by using BRIDGMAIPS data for the compressibility of
water. Up to pressures of from 3000 to 4000 atm the compressibility of water
does not play an im ortant part and the approximated formula v - 14 P may
be used (p in kg/cU, v in m/sec). At such velocities REYNOLD'S numbers be-
come very high (order of magnitude 105). They are mentioned in a table for a
nozzle of 0,6 mm. The temperature of the jet increases with an increase of
preasuroand therefore also with an increase of velocity. Heating by frIction
and adiabatic cooling act in opposition to each other. Ala, a negative
JOULE-THOMSON effect becomes noticeable. According to the opinion of the
authors the experimentally attainable velocity of a jet of water ejected from
a nozzle is limited only by the JOULE-THOMSON effect, for the temperature of
the jet increases to such an extent at a certain pressure that the water
evaporates. The authors found such an evaporation to take place on the
occasion of an experiment carried out at 5000 atm, which fact may also be
confirmed by rough calculation. The jet of water was investigated by means of
a cinematographic camera producing 5000 pictures per sec, so that the general
properties of the jet could be examined.

ABSTRACT In the laboratory for the physics of ouper-high-pressures of the Academy

which corresponds to a jet-velocity of 600 - 650 m/sec- it was necessary
to construct a fast-running machine (1000 wave-revolutions/min.) with an
electromotor of 240 kW. Two models of such a machine were constructed.
One of them had an output of 1200 1 p.h. with a consumption of 20 - 65 k7t
at different pressures, the other had an output of 1800 1 p.h. at 110 -
120 k9 and approximately 2000 atm. overpressure. Different jet-diameters
facilitated the modification of the pressures before the jet. The jet
has behind the conical part with a certain narrowing angle a cylindrical
part of a certain length. The inner surface must be carefully polished.
According to Bernoulli, the velocity for a perfect incompressible and for
a compressible liquid in dependence on the pressure was calculated and

shown in a diagram. The general character of the passage of a jet through
the atmosphere was determined. It turned out that, with an increase of
jet-velocity beyond sound-velocity in air, the wator-jet becomes more
compact, the conical aperture-angle, however, decreases. The thermal
effects occurt-..g on the occasion of throttling become compensated in a
certain deFree. on the occasion of throtteling a compressed liquid a
heat-4ffect viz. the Joule-Tomson-offect is produced. Experiments show
that the liquid ejected from the jet actually becomes heated. It is the
author's opinion that the only reason for the existence of a limit for
the experimentally obtainable velocity of a water-jet ejected under
pressure from a jet is due to the Joule-Tomson-affect, for, at a certain
pressure, temperature rises to such an extent that the water evaporates,

ABSTRACT: Pressing of metals in the cold state can be effected
either by means of a plunger pressing against the work
or by means of fluid under high pressure. The first method
is at present very widely used but owing to the very high
friction forces between the material and the die walls it
cannot be applied to metals with high yield points. This
obstacle can to a certain extent be eliminated by using the
second method, namely$ pressing by means of the hydrostatic
pressure of a liquid. The here described experiments were
card 1/3 carried out by the Laboratory of Super-high Pressure Physics
of the Ac.Sc. (Laboratoriya Fiziki Sverkhvysokikh Davleniy

information on pressing metals by means of liquids under

relating to the rheological behaviour of the materials
pressed by means of a liquid. For materialising the process
apparatus was built whicil permits pressing by means of
pressures up to 12 000 atm. The upper limit of the
pressure is given by the pressure which can be produced by
the compressor built in the Laboratory. A photo of the
apparatus is shown in Fig.2, p.49, whilst Fig.3 shows the
attachment for pressing the material through the die and
Fig.4 shows the die geometry. The die was produced from

theoretically calculated values, which are compe-red with
experimental results. Compared to the process of pressing
metals through dies by means of a plunger, pressing of dies
by applying hydraulic pressure has the following advantages:
the total pressing pressure is considerably reduced since
there are no losses caused by friction in the cylindrical
part of the die; the resulting reduction in the total
required pressing force also leads to a reduction of the
friction coefficient between the metal and the die; the
reduction in the friction coefficient between the metal and
the die leads to a considerable reduction of the optimum

ADSTRACT: Bridgman, P. W1. (Refs.1 and 2) determined the shear force
for a number of elements at pressures of 25 000 and
50 000 atm. The authors of this paper have continued
these investigations and for this purpose apparatus was
built which is similar to that used by Bridgman. For
some of the elements which were investigated by BridGman
data viere obtained which are in agreement with the
numerical values of Bridgman. However, the question arose
whether a relation exists between the shear force at
elevated presoures and the periodic number similar to that
which was established by one of the authors and
A. I. Likhter (Ref.3) for the dependence of the
compressibility of elements at elevated lueriDeratures on
the periodic number of the element Z. It can be seen
from Fig.1 that the shear force on elements shows a
periodic dependence on Z and its absolute value increases
Card 112 with increasingg pressures. It is of interest to point out

Dependence of the shear force of elements on the periodic number
at hiGh pressures.
that the shear force apparently depends only on the
number of the external electrons and not on their total
number in the atom and also not on the type of the
crystal lattice. It is also important to point out that
the shear is inverel, proportional to the compressibility
of the element (Fig.15. Thus, it can be concluded that
the viscous flow of a solid under pressure is influenced
solely by the external electrons of the atom. This
problem is at present bein- investigated at appreciably
higher pressures by means of the apparatus %rhich has been
built.

ABSTRAM The properties of matter may be changed arbitrarily by
applying high pressure. The grade of compressibility of dif-
ferent elements varies with their molecular structure. Theore-
tical and experimental research conducted by Soviet and foreign
scientists showed that the difference of compressibility of
different elements decreases with increasing pressure. At a
pressure of 1,400,000 atm the difference of compressibility
is very small and periodicity in dependence of the specific
atomic number disappears completely. Experiments to study
the mechanical properties of hard substances under pressure,
and especially under shearing conditions, were conducted by
the Laboratory of Physics for Superhigh Fressures (Laborato-
riya fiziki everkhvysokikh davlenii). In addition, the same
laboratory conducted experiments with the manufacture of alu-
minum wire under high pressure - in order to obtain wire of
improved pliability and strength. Scientists were convinced
that the resistance to rupture increases when the object is
Card 1/2 placed in a liquid which is under high pressure, for instance

25,000 to 30,000 atm. Even such brittle material as cast
iron becomes resistant to rupture under a pressure of ap-
proximately 30,000 atm, whereby the resistance to shearing
stress amounts to 336 kg per sq mm of the cross section. One
brand of steel showed at 28,000 atm a resistance of 340 kg
per eq mm. If the pressure could be raised to 100,000 atm
it must be assumed that the breaking strength would be in-
creased to 826 kg per sq bim. The role of micro cracks per-
taining to the pliability of rock salt under pressure was
studied by A.F. Ioffe. The author reviewed also the ex-
periments conducted for the production of artificial diamonds,
and mentioned the fact that synthetic diamonds are being
produced in the USA.

the fluctuations of pressure in front of the nozzle at a

at a hif7h velocity of jet, about 500-600 m/sec, an estimation
of the friction Droduced on the metal wall is very difficult.
For this purpose the attempt was made.to detvrmine by
experiment the dependence of the water-jet friction at the
nozzle wall on the diameter and on the quantity of pressure
Card 1/2 in front of the nozzle. The experiments showed that the

diameter of the nozzle as on the pressure. Based on the

more and a pressure below 700 atmospheres the frictions on
the nozzle wall may be disregarded in the outflow of water
from the nozzle. There are 2 fiiNreB and 3 references, all

ABSTRACT3 Here a theoretical computation of the dependence of the pressure-
pulsation-smoothing degree in the receiver on the capacity of at
preasure produation in this receiver by means of a hydraulic ultra-
high-presoure compreaBor wan carried out. The influence of the re-
oeiver-capacity (contenta) on the I)refigure-puloatioti-emoothirig dc-
gree in the receiver is investigated by experiment, The results of
the computation were compared with those of the experiient with re-
gard to the pressure-puleation-amoothing degree of the water in
the reoeiver and it was ascertained that the theoretical coiaputa-
tion in spite of a number of simplifying assumptions shows a oatia-
fyin*onformity with the data of the experiments. On account of the
results of the experiments the water jet, which flows out of a 5-6
liter receiver at supersonic velocity, may be looked upon as vell
smoothed with regard to the impulse-pressures and consequently also
with regard to the impulse-velocitics.There are 5 figures, 2 tab-

Abstract : Measurey--nts of the Hall effect in 99.99% pure bismuth
were measured in a special matrix, vhich can withstand
a pressure (P) up to 30,000 kg/cm2. It turns out that,
as p increases, the Hall effect diminishes gradually,
and in the mod-ification III it 'becomes three orders of
magnitude smaller than at normal pressure. The depen-
dence of the resistance on the magnetic field in modifi-
cation III also falls beyond the limits of the
sensitivity of the mmsuring apparatus.

TITLE: A Valve for Ultra-High Pressures (Ventill sverkhvysokogo
davleniya)
PERIODICAL: Pribory i tekbnika eksperimenta, 1~58, Nr 6, pp 114-115
(USSR)
ABSTRACT: The valve is shown diagrammatically in Fig.l. It consists
of: 1) the body, 2) a needle or a spindle which covers an
aperture in the body of the valve, 3) a special tightening
device for the needle, 4) a lock and 5) a screw; these last
two items can impart a progressive motion to the needle.
The return motion of the needle is caused by the action of
the liquid or gas pressure on the needle and by a spring.
The screw 5 is turned by means of a small flywheel which
is inserted on it, or by means of a worm drive. The problem
of tightening or gasketing the needle pre sentedPv%Qpe.4Uf f icul-
ties. It was finally solved by adopting a number of cylin-
drical coaxial shells (as shown in Fig.1). The valve was
tested in a laboratory with liquids at pressures up to 8000
atm. and with -Dases (nitrogen) at pressures up to 3000 atm,

ABSTRACT: In a number of cases, it is of great importance to evaluate
the mAximum internal pressure which will bring about tube
failure. It can be assumed that the pressure at which
tube failurewill occur depends basically on the thickneGs
of the tube and the strength characteristics of the zube
material (Ref 3). However, this assumption requires
experimental confirmation. For this purpose, Laboratcrj,,,.

are graphed in Figures 2 - 5. The obtained
experimental curves are not in agreement with any
of the semi-empirical formulae (Ref 4) proposed
for calculating the preUMire at which
tubes fail.
Lomakin (Ref 5) published in 1955 theoretical
work on the calculation of tubes, taking into
consideration high elastic-plastic deformationn.

ABSTRACT: First it is shown that the reDults obtained by F.W.Brideman
(Refs 2 and 8) are not constant and, to a certain extent, un--
certain, A measurement of the electric conductivity of silicon
of the p--type in dependence on the pressure is repeated. A
silicon monocry3tal, produced according to the method of Chokh-
rallskiyA'tteState Institute of Rare Metals was used as sample.
It had the forn of a paralleleyiped with 9,8 x 5,6 x 4,0 mm.
A Wheatstone bridre of the type MK!_.-.Aq was used for the
measurenent of the electric resistaDCO~ A multiplier (analo-

They show that the sample resistance does not chanj:e in the

of the =ount of arn:,eraj,(.- in the0region of o,2 4- lo nA . The
opecific saml~le resistance at 2o amounted to 18,4 ohm cm. The
measurement of the sample resistance was carried out gradually
up and down under pressure. It was found that the electric re-
sistance of silicon in reduced with increaoing pressure. It was
shown that pure silicon of the p-type has tile ame effect sign
as vermanium of the p type and ae'.enium (Ref 21%5 resp.). No
such great hysteresis of the silicon resistance by the pressure
was observed as in the case of Bridgman, It is pointed out that
the electric resistance in the caoe of silicon of the p.-type
is to a i3reat extent influenced by the chemical purity, the
composition of the admixture, the thermal and mechanical pre-
treatment. S. A. Ratenberg put the silicon crystal at the
authors' disposal. N.I.Chetverikov helped to produce the con-
tacte. There are 2 figures and lo references, 3 of which are
