ABSTRACT: Experiments have been performed to test the effects on human aubjects
of a prolanged stay in a helium-oxygen atmosphere. Two subjects were kept in a
sealed cabin for 10 and 25 days, respectively, after which time atudiea were made
on the functions of the central nervous system, the respiratory system, and
the cardiovascular system and on gas exchange, thermal exchange, speech, aid hear-
ing. The experiments indicated that a helium atmosphere affects the thermal

pheres, produced in a helium atmosphere a sensation of chilliness and a lowering
of the skin temperature. The comfortable temperature ranges in a helium-oxygen
atmosphere were 24.5--27.50C during the day and 26--290C at night, when the
i. subjects were sleeping. Investigation of the functions of the central nervous
system, conducted in the comfortable temperature range for belium atmospheres,
indicated a gradually growing inhibitory process in the cortex of the brain, which
manifested itself by the appearance of low-frequency oscillations on the encepha-
logram and by an increase in the duration of the latent period of conditioned
motor reflexes. Analysis of the experimental data indicated that these changea
were duo to prolonged hypodynamia and not to substitution of helium for nitro-
geii in the atmosphere. General well-being and work capacity of the subjects were
not affected by the helium-oxygen atmosphere. The helium atmosphere also had no
effect on external respiration, the cardiovascular system, gas exchange, or
energy consumption. Minute changes observed at the end of the experiment were
due to hypodynamia rather than to the changed atmosphere. On the otheehand, it
was found that a helium-oxygen effects human speech, raising the frequency of
speech sounds by 0.7 of an octave. Glarity of speech is lessened somewhat but
not to the point of unintelligibility. The auditory functibA of the subjects
in a helium-oxygen atmosphere apparently was wt affectede These experiments

ABSTRACT: An investigation was conducted to guage the physiological
effects on man of prolonged exposure to a helium-oxygen atmosphere in.
a.heirmetic 'chamber. Exposure was for 22-30 days. Nitrogen was re-
moved from the cabin atmosphere by first introducing pure oxygen
followed by helium. The average composition of the experimental at-
mosphere was 22.53 oxygen, 76% helium, at%d 1.5% nitrogen. Carbon di-
oxidet concentration did not exceed .7%. The rate of ventilation was
160-180 liters/minute. The temperature comfort xone of the test

dity was 30-60%. For control purposes, each test subject was also
atudied under normal conditions. Caloric intake of test subjects was
:1600 kcal per day. It was observed that the skin temperature of sub-
jects in the helium-oxygen*atmosphere was 2 degrees cooler than in
normal air. Bioelectric measurements revealed no alterations n higher.
nervous activity. Similarly, the cardiovascular system, respiration,.
.zrnd basal metabolism were essentially normal under these conditions.
Any physiological abnormalities observed were directly attributed to
prolonged adynamia and isolation. The only noticeable effect that
the helium-oxygen environment had on subjects involved lowered clarity
of speech and changes in voice pitch, which at high frequencies were
,seven-tenths of an octave higher. The author feels that employing a
helium-oxygen mixture for space cabin ventilation is justifiable from
the'standpoint of the improved heat exchange which the test subjects
exhibiteds Thi.s greater thermal efficiency in due to the higher ther--..-'
rtal conductivity of helium in comparison with nitrogen. For this
.reason, the ventilation rate could be significantly lowered, wV6 -Is

the helium-oxygen atmosphere has greater thermal conductivity, it
follows that man could tolerate a higher ambient temperature. This
was reflected in short (24-hr) tests in which subjects comfortably
withstood temperatures of 27-30C. In general, the results of this
investigation strongly support the feasibility of employing a helium-
oxygen atmosphere during prolonged manned space probes.

TITLE- On the Performance of a Plane Piezo-Vibrator Under the Conditions
of Unidirectional Radiation
PERIODICAL: Izv, Leningr. elektrotekhn. in-ta, 1957, Nr 31, PP 46 - 59
ABSTRACT: The author expounds the results of calculating a plane piezo-
vibrator made of an X-cut of quartz. The calculation method is
similar to that, which usually is applied to calculating the
passage of plane waves through plane parallel plates. rMe formulae
obtained for the radiation intensity are analyzed for some special
cases: 1) the media on both sides of the vibrator are equal and
have finite wave impedance; 2) the vibrator comes on one side in-
to contact through a X /4-layer of an arbitrary matter, with a
medium; 3) the vibrator comes on one side into immediate contact
with. a medium, the wave impedance of which is equal to zero. The
latter case ' most important for practice, is analyzed in detail.
Card 1/2 The author shows that the optimum thickness of the vibrator, i,e.

the thickness, with which maximum power output is yielded, will not be equal
to IL /2, if the ratio of the wave resistance of the load to that of quartz
is greater than V-2. The greater the wave impedance of the load, the nearer
the optimum thickness of the vibrator to X /4. The author gives the fre-
quency dependence of the vibrator intensity for various values of the load
wave :Impedance. In proportion tolnoreasing the load wave impedance, the
frequency characteristics become more gently sloping. When the wave im-
pedance of quartz and load are equal, the vibrator loses its resonance pro-
perties. The author studies in detail the part of an intermediate lubrica-
tion layer in the vibrator radiation into a solid medium.

ABSTRACT: Ultrasonic -waves are often emitted or received via an iaterlediato
system consisting of one or more plane-parallol layers. For exampAek
in studies of solids by means of ultrasonic waves, one or more inter-
mediate layers are placed between a-vil-rator or a receiver and the
solid in order to Improve the efficiency of energy traneer. 3u ch
intermediate layers and their effect on emitted radiation are discussed
in the present paper. The author shows that, if one quarter-wave layer
is used between a piezovibrator and a medium, the emission intensity at
a particular frequency may be increased, provided the layer has lower
acoustic impedance than the impedance of the medium. Larger increasea
of intensities at chosen frequencies can be achieved by the use of twe
or more layers. For This purpose an ood number of intermediate layers
is usually employed for irradiation of solids, while an even number of

such layers is more convenient in irradiation of liquids - The author
verified the theoretical equations obtained by comparison with
experimental results. For example, Fig 3 curve 1 shows the frequancy
characteristic of a vibrator emitting directly into water, while
curve 2 shows the same vibrator emitting via an intermediate double
layer consiting of water and a glass plate. The crosses in Fig 5 are
experimental values and they show good agreement of the theoreticai

PERIODICAL: Dijklady Akademii nauk SSSR, -1958, Vol 123, Nr 6,
PP 1033 - 1036 (USSR)
ABSTRACT: The classification and theoretical utilization of the experi-
mental data concerning the boiling temperatures of binary
systems in publications do not suffice to establish the
applicability of measurements of these temperutures in the
physical-chemical analysis. For this reason, the authors
additionally investigated the folloving systeiis: dioxane.-
ethylene-glycol and nitro ben2,eneisobutyl alcohol. Their
boiling isobars are of the same type and show a negative
deviation from the standard curve. This is due to the
dissociation of associated molecules of the components at
their dissolution. For the determination of the boiling
temperature and the vapor composition a modified ebullioscope
Card 1/3 (according to kefs 6,7) was used. The boiling isobars of' the

It 1'Y1YJGiCU1-C1WV1iOU1 Analynin of Binary Liquid Systems SOV12o-123-6-21150

rational systems may possess 3 types of singular points:
a) an upper point, b) a middle one and c) a lower one. In the
6 rational systems investigated by the authors tho types a) and
b) were determined. The most characteristic ones were: piperidine-
mustard oil (Fig 1) and ethylene-diamine-mustard oil. An
isobar of the b-type is shown by the systems: water-acetic an-
hydride and diphenyl-amina-mal.eic anhydride. The condensation
curve of the water-acetic anhydride system (Fig 2) consists
of 2 Darts with different ascent. These parts intersect (as
well as the evaporation curve) in the singular point, This
suggests the existence of a compound not dissociated (acetic
acid) in the vapor. Although no boiling isobars of the c--type
could be found experimentally, their theoretically possible
existence is supported by the model-method (Ref 9). In addition
to the singular points at the same time the occurrence of
azeotropes on the isobars is possible which are formed by
the compound and by one of the components. This occurs in the
Systems: diethyl-amino-phenyl mustard oil and ethylaniline-
phenyl mustard oil (Fig 3). By rounding off the singular points

parts of boiling isobars, corresponding curve types of the
irrational systems can be constructed (Ref 10). The authors
investigated 5 of such systems by means of the ebullioscope:
stannous chloride-ethylacetate, PC1 3 - C6H5CHO, chloral
water (Fig 4), chloral ethanol, ethylene-diamine-water. The
results of the measurements of the boiling temperature are in
accordance with those of other phynical properiies and
complete them considerably. Thus$ the ebullioscopic determina-
tion can be regarded as an efficient method in the physical-
chemical analysis of liquid syste:ns. There are 4 figures and

TITLE: Spectrophotometric Investigation of Picrates of Aromatic
1~ydrocarbons in Solution
PERIODICAL: Doklady Akademii nauk SSSR, 1959, Vol 128p Nr 1, pp 106-109 (USSR)
ABSTRACT: In the present paper the authors attempted to solve the problem
.as to whether aromatic hydrocarbons may be determined on the
basis of light absorption of their picrates. As a solvent
1,2-dichloro ethane was used which solves pitric acid and hydro-
carbons as well as picrates. In a relatively wide spectral range
the absorption curves were plotted and for a series of solutions
the molar extinction coefficients E were computed (Fig 1),
Absorption spectra of the solutions investigated may be. div--'-,ded
into 3 ranges: In the shortwave range (222-300 m~t) absorption
bands characteristic of naphthalene hydrocarbons occUr. In the
medium range there is the absorption maximum of picria acid
040 ma). For differently concentrated solutions and solutions
with heterogeneous hydrocarbons the extinction curv6s are equal.
The long-wave range is characterized by the absorption of
picrates. Besides naphthalene and its mothyl-substituted
Card 1/3 derivativesp also individual non-condensated aromatic

hydrocarbons were investigated. with all bolutions investigated
absorption edges are almost parallel (Table 1) in the visible
part of the spectrum. The investigation was carried out on the
speotrophotometer SF-4 at room temperature. The following
investigation results were found: By formation of picrates of
aromatio hydrocarbons, the absorption edge of picrio acid is
shifted towards the longwave range. The amount of shifting
depends on the nature of the hydrocarbon and on the concentration
of the oolution. With an increase in the number of alkyl grcups
in the hydrocarbon molecule, the absorption edge is shifted
correspondingly. The shifting of the absorption edges is hardly
influenoed by a complication in the structure of alkyl groups~
or by a variation of their position in the ring. This shifting
may also serve at a certain optical density just as the
absorption quantity on a certain wave length for the
determination of aromatic hydrocarbons by the spectrophotometric
and oolorimetric method. The authors thank L. A. ]Ukhazedova

PERIODICAL: Vysokomolekulyarnyye soyedineniyat v- 3, no. 4, 19611 594-601
TEYT: This paper reports on the design of an apparatus for the continuous
recording of thermomechanical curves (TMC) and on some experiments conducted.
Fig. 1 shows a schematical drawing of the apparatus. 0 is the sample con-
tained in a vessel of 4 mm. inner diameter and 2 mm, height. It is part of
the heater 6 (aluminum). & is cooled with liquid air before the beginning
of the experiment by means of the Dewar vessel A, subsequently heated at
constant temDerature rise. The linear increasing voltage ofAJTH, the
thermocoupleTY and the electronic relay P2 serve for this purpose. P2
switches in the heating current as soon as the emf of TY has reached the
voltage ofAJ114. The sample is loaded with the weight r of the stampTr, the
weight of which is equalized by the scale beam K and counterweight. The
contact needle W is fixed at the end of K. The vessel with the samples is

fixed at the cross beam T by means of rods. The micrometer screw 11 forms
part of T and is moved by means of a CA,-2 (SD-2) synchronous engine.
(Insulators are between K and 0, as well as between T and M). A separates
from M when the sample is deformed (falling of the stampIT). Subsequently,
the relay PI switches in the engine (a) of the record chart of the YnT-09
(EPP-09) recorder and SD-2, which are synchronous until contact is re-estab-
lished between M and M. The maximum recording rate of deformation depends
on the rpm. of the Warren engine. The temperature of the sample is measured
with the thermocouple TO, which is connected to the input (b) of EPP-09.
The cold junctions XCare kept at 200C by means of the thermostat. The po-
tentiometerTrCpermits the recording of both positive and negative tempera-
tures. At (c), N2 is blown through. A special device was designed to bring
various diagrams to the same scale by means of projecting the record chart
located on an inclined glass plate onto a horizontal table. Fig. 3 shows
the TMC of polyvinyl chloride at different stress. At 100, 125, and 1500C,
the diagrams of Pig- 4 werO obtained herefrom. Linear function between
deformation and stress could be observed only in highly elastic state (up
to 1000C). At higher temperatures, a deviation from linearity was observed
owing to plastic deformation. Pig. 5 shows the dependence of the vitrifica-

with respect to zero stress. Similar investigations were also carried out.
on polyinethyl methacrylate and the copolymer from the allyl dichloro vinyl
ester of phenyl phosphinic acid and 3%o methyl methacrylate provided by
N. I. Riznolozhenskiy and A. A. Muslinkin. The optimum stress was found to
deoend on the kind of thd polymer to be investigated. At hi,h .9tre.,is, TV
can be accura'tely determined, while the determination of TS requires a orriall
load. Furthermore, the course of TCC was found to be hi(;hly dependent on
the preparation of the sample. Fig. 8 shows this for polynethyl metbacrylate.
V. A. Kart;in and V. L. Tsetlin are mentioned. There are 9 fitures and
8 Soviet-bloc references.
