which speaks in favor of the applicability of such
calculations for the flow of mercury vapors through a glass

the impossibility of the description of tile change of flow
and of the composition of isotopes by means of Clausin,31a

iron and through a copper tube are probably based on the

ABSTRACT: The compressor described is illustrated in Figure 1.
It is designed for compressing large volumes of liquids
to the pressures of 8 to 10 kati. It is a periodically
operating machine in that one cycle is completed
during each revolution of a crankshaft. The operatIng;
cycle is as follows. From a container, the "operating"
liquid is admitted through the gland 9 into the annular
space between the cylinder 8 and the throttle 7 . The
liquid has the input pressure of about 30 atm and through
three apertures in the throttle is admitted into the
annular space formed by the rod 10 and the internal
surface of the piston. When the piston is lowered, the
liquid is admitted into the channel 6 through the
apertures in the rod and results in the lifting of the.-Y

As soon as the rod passes the lower dead point, the
compression cycle is commenced. At the instant when the
pressure in the compression chamber is several times
higher than that behind the valve 12 the latter is
opened and the compressed liquid is e3cl)elled. If the
compressor operates with water it is necessary to lubricate
the piston and the rod. This is done by employing a
hypoid grease to the piston 6 and rod 10 and the
tightening cylinders 14 . The performance of the
compressor is illustrated in Figures 1. and 2. Curve I
of Figure 2 shows the change of the compressor performance
(in litres/min) as a function of the force applied, the
input pressure being constant. Figure) 3 illustrate.-ti the
losses due to piston friction as a function of the pressure
applied. Curve I of Figure 3 represents the hydrostatic
pressure, while Curve 2 shows the force received by the

TEXT: Previous work (Refs.11 ta 14) had shown the possibility of
purifying beryllium from certain elements despite similar
volatilities of these elements and beryllium. The present work
-as carried out using a diffusion pump giving residual. pressurea o
10-5 to 10-6 mm Hg. A beryllium oxide crucible was used for
evaporating the beryllium, heated by molybdenum spirals. The
condensing column, placed over the crucible, is shown in Fig.l.
Condensation took place on the molybdenum plate on the inside of
the column. The condensation surface was heated to 90.0 to 11000C
(measured by a pyrometer and by thermocouples) and the optimum
temperature was determined. Fig.2 shows the ratio of the impurity
content in the original material (qp) to the impurity in the
condensate (ql) plotted against the temperature of evaporation
(1 - iron, 2 nickel, 3 copper, 4 silicon). Fig-3 t5hows

A similar change occurs with aluminium. Fig. 4 shows that 85 to
90% of the original material can be distilled before the impurity
concentrations increase to any extent. Fig-5 shows a column with
baffles which has been used very successfully. The table gives;
the chemical composition of the initial beryllium (ser-ond column)
and the beryllium after distillation (third column using a simple
condensing column, and the fourth column using 1)nffles). The
purest beryllium' is obtained in the middle zone and is 99.99% alIart
from oxygen (0.04%) and carbon (0.02%). The carbon originates from
oil vapours from the diffusion pump, and the oxygen from Eublimation
of the crucible material (Beo) and reactions between beryllium and
the crucible material to form Be20- The microhardness of the
distilled beryllium (99.98%) decreased to 130 kg/i=2 for monocrystals
and the hardness of the cast metal was 100 Hb - et decrease by a
factor of 1.5 to 2. The low plasticity of the bcryllium is
explained by the considerable quantities of carbon and oxygen still
present. There are 5 figures, 1 table and 16 references:

methods, and annealed at 1000*C for one hour in high vacuum,
Three p%aks were observed in the temperature vs internal friction
(Q-1.10 ) curve of zirconium, i.e. at 260, 645 and 875% (Fig-3)-
The peak at 645% was caused by viscous flow in the grain boundaries~
The peaks at 260 and 875 'OC wereof more interest. These peaks did
not change with change in frequency (from 56 cps to 29 and 72 cps)
of the applied oscillations. This confirmed that the waximum at
2600C was caused by a transformation in the metal structure. The
height of the peak at 2600C depended on the rate of heating of the i
sample, At rates of 20C/minute and less the maximum did not
appear and at higher rates the value of the maximum increased.
It wits proposed that this was caused by the formation of hydride.
Additional experiments showed that the peak disappeared after
treatment in vacuum at 7000C for seven hours which removed the
hydrogen, The peak at 8750C was present even at the low rate of
heating and corresponded to a polymorphic transformation. A peak
was observed in the internal friction vs temperature curve Of
beryllium between 600 and 7000C. This peak also appeared after

TEXT: The investigation of the thermal properties of metals and
alloys at high temperatures is of considerable interest in the
theory of niietals and for practical applications. There is no
published data in the Soviet literature on the thermal
conductivity of refractory materials and only a limited number
of non-Soviet papers. In the method described the sample in rod Ix
form is heated by an electric current in a vacuum. Differ&;tial
equations are set up, taking into account the Stefan-Boltzman
radiation law, a,--d formulae are derived for determining the
coefficient of thermal conductivity and electrical conductivity
of the sample material. In order L'o obtain the required data
it is necessary to measure the potential difference on the working
length of the sample and also the terip6rature distribution over the

either in length or diameter. The samples are held in water
cooled clamps in the vacuum chamber and the potential difference
along them is measured by means of two tungsten or molybdenum
probes and a potentiometer. The temperature is measured by means
of a micro-optical pyrometer omn-oiq iomploiq), fastened to the
moving carriage of a cathetometer, which enables an accurate
temperature distribution to be obtained. The thermal

possibility of making a more rigid division of the experimental
values of thermal conductivity into the electron and lattice
components at high temperatures. The electron component is
independent of temperature while the lattice component decreases
with increasing temperature. The thermal conductivity of Mo and
W is measured at temperatures up to about 22000C and shown to
approach a constant value asymptotically. This value, must
eqiial Xe. Values of X.b are given for Pt, Pb and Cd for
temperatures up to 5009 282 and 2520C respectively. Valuen of

from 0.071 at 9000C to 0.012 cal/cm.0C.sec at 22000C. The

In the case f Cu it varies from -2.3 x 10- at 1000C to

be incorrect. 2) At temperatures near to the Debye temperature

TITLE: On the problem of the solubility of impurities in

PERIODICAL: Fizika metallov i metallovedeniye,-v. 111,,no. 1,
1962, 128 - 130
TEXT: Data on the solid solubility of nonmetallic
impurities (carbon, nitrogen, oxygen) in beryllium are scarce
and sometimes contradictory. This prompted the present authors
to study this problem by comparing the temperatkLre-dependence
of the-lattice parameters of high-purity berylfium with that of
beryllium containing nonmetallic impurities in quantities
sufficient to ensure the formation of saturated solid solutions.
These relationships are demonstrated in Fig. 1, where the
magnitude (IcX) of a *(lefthand scals) and c (righthand scale)
is plotted against the temperature ( C), the broken and

TEXT; The above problem was studied theoretically and experimental-
ly in view of the advantages of this process and high quality of
the resultant coatings, By coneidering a vapor interacting with a
solid to form a layer of product upon the .latter, w1lich is of thick-
ness 1 after a time t, and assuming that the vapor is supplied into
the reaction zone at a rate much lower th2ln the rate of mutual. dif-
fusion of reactants through the layer formed, it is shown on general
grounds that- 1 should vary linearly with t. The relation between 1
and t becomes parabolic if the rate of chemisorption of the vapor
dpon the solid surface is higher than the rate of diffusion through
the layer. To confirm these results 10 X 10 X 1,5 mm sPeciment, of' Ta
and 11o were silicided by a method similar to that described by
Gorbunov, using Si powder (0-5 - 1.0 mm), at 12009 12509 1300 and

ABSTRACT; It has now been established that the radiative growth of
uranium Is largely determined by the nature and promidentfeatures of
its texture. An attempt has been made to destroy the uranium texture
resulting from a single hardening process by sub4ectiN; it to govetal
such processes (up to 4 times)., The result was a*pulvorization. of the

creasing radiation. The tests made In this conneotion Included harde--
nin,; the uranium eamples In the beta- and gamma-phases, followed by
the slow-cooling and water-cooling methods. The test results indicate
that the texture of.hardened uranium is determined primarily by the
paranetersof the heat treatment of the metal, and the following con-
plusions are therefore justified: 1) thei texture of hardened uranium
depends on the nature of the heat treatment but primarily on the dura-
tion of exposure to high-iomperaturo ph~aaes; 2) the greatest.deatruc-
tion of the texture was noted in the samples that had been heat-treat-
ed under the effee. of tensions produced by theralo gradients or ex-
ternal efforts, and 3) in the case of low and moderate beating opeads,'.
the texture of hardened uranium is determined to a large extent by the'.

ABSTRACT: Inasmuch as the coating of refractory metals ~w'lth md Ilybdenum dis Ilidide in
known as a prospective method for preventing high-temperallure (~)Jdetion, .110i-e7effect
of some &dditives on the growth rate and the structure of the tAlicide laarer o6 molyb

brittleness and an inadequate thermal stability) may depend. on :tbe preparl'itive method
and on the purity of the ini

The effect of AlPFe.11Cu11Ti`,,"and B sed as additives, and of the residual 9:" stres-

relative elongation, and relative plas ity of nickel was examined at 250 and 6000C
and also the temperature dependence of~cternal friction (Q-1) for nickel containing
0.005-0.1% B was examined in the 200-600C range. Samples of ni C 1-boron alloys were
prepared by fusing mixtures of H-0-grade nickel and NIB standard material in an elec-
trical furnace. After 70-80% deformation for 4 hour at 4000C, ihe samples were held
for 2 hours at 8000C. In general, boron had a beneficial effect on the mechanical pro-
perties of nickel. Specifically, boron was found to strengthen the alloy crystals and
the intergrain boundaries within the alloy, to improve the Internal grain structure and

ABSTRACT: A theoretical investigation is made of several types of gyro-
scopic rocker devices used in the study of angular motions on
ship models in model-test basins in place of artificial surface-
wave exciters. An analysis of the standard equations of gyro-
scope theory leads to the following conclusions: 1. Single-rotor
devices are capable of producing combined rolling and pitching
or rolling and yawing motion. 2. In the single-rotor devices the
arriplitude of the perturbation moment varies as a function of
the pitch and yaw and of the frequency of the roll. 3. Two-rotor
devices with swiveling rotor-axes are not subject to these limit-
ations and can be r ecorrinn ended unqualifiedly for test-basin
