ABSTRACT: An installation is described that permits a fairly
rapid logarithmic-
scale recording the intensity of sound pressure in a tank with a
pickup travel.-
ing at 7. 5 cm/sec along the tank. A block diagram is presented
of sound-
intensity recording by a "Neyman" type recorder. The recording
method sug-
gested has been verified in the case of sound propagation in a
homogeneous
medium (water); in this case, the graph agrees well with the
calculation.
Sound-intensity experimental curves are also presented for two
cases of a
stratified nonhornogeneous medium.

ABS TRALT - When a sound beam falls on a transitional layer
batwean two
homogeneous media with different values of sound velocity,
refraction and reflection of sound occurs - The present paper
compares attenuation of sound) found experimentally after
through a layer with a discontinuity of sound velocity, with a
value obtained by a theoretical calculation which allows for
broadening of the sound bearn in this layer. Such a
transitional
layer was formed by diffusion b9tmeen a solution of rociic
salt and
a layer of uater poured on top of this solution. ThicLness of
this
layer may be found experimentally by measurement of salinity
at
various depths and~jcalculation using the diffusion equation,
assuming that the medium is inhomogoneous and the salinity
gadi-3nt
occu;-s only in the vertical direction. Distri1xition of the

Attenuation of a Sound Beam in2~avarsinG a Layer with a
Disconrinulty of
Velocity
velocity with depth in such a layer is similar to the
distribution
of radiowaves in the ionospharic(r-instai4 transitional layer
(FiC, l/.
The sound scrarce was in the salt solution and it emitted a
sound
beam upi);ards in a Fralinhofor zone 180 wide. Sound pulses of
40-50 Psec with a carrier frequency of 500 kc/s and a
repetition
frequency of 50 c/s viere used. The acoustic field at various
levels
on both sides of the transitional layer was investigated by
iiiaans
of horizontal displacement of a hydrophone. Graphs of
dependenca
of the acoustic pressure on the distance from the source were
constructed. An example of such a graph is given in Fim 2. If
the losses in the transitional layer itself are neglected, then
decrease of the acoustic intensity after traversal of the
layer may
be ascribed to (1) additional broadenincr of the sound beazi
on pgssin-
through the lajer (Fig 3), and (2) reflection of sound from the
transitional layer. The second cause can be safely neglected
because
the reflection coefficient frmi the layer in all experixients
did not
exceed 0.1~..

Abstract No 29654)
A schematic of conversion of varying dc electric voltage into
ac is
presented. It facilitates recording on a high-speed
logarithmic level
recorder. The converter consists of a multivibrator operating
on a fre-
quency of 10 kc ', a modulator and limiter.. built on two
rectifiers. Re-
sults of measurement are presented shoving the dependence of
the level
of sound pressure in the tank on distance in a stratified
unhomos-ecus
medium with a constant temperature gradient 0,80 for each cm
of depth.
The measurements were carried out using pulse techniques. The
results
agree with computations based on geometric~ acoustics.

characteristic of aerobic processing) can easily be
precipitated by the
addition of Fe-AL -cations. Further physical and chemical
purification is
simple,* without significant loss of water from the system.

used (Chlorella and bacterial flora), mineral salts were not
assimilated
but accumulated to saturation and then began to precipitate out
of solution.
This led to pH fluctuations in the medium. 2) Prolonged (5
months) culture
caused saturation of the medium with soluble and nonsoluble
humus-type
organic matter. Nonsoluble matter can be removed by
precipitation, but
the soluble matter accumulates and suppresses the v-ital
activity of the
Chlorella and bacteria. Physical and chemical purification to
remove
soluble organics is required from time to time to prevent
deterioration (if

effective for removing sodium and sulfur. NaCl (up to 2 g/liter
stimulated
.the algae, and larger amounts (up to 4 or 5 g/liter) did no
harm. Table 3
shows the amounts of various elements present in the medium at
the begin-
ning, used by the Chlorella, and present in the medium at the end
of Ahe
process.
One app~oac'h to these problems may be the alteration of human
diet to
bring the composition of excreta more closely in line with the
requirements of
the algal-bacterial linlr- For instance, human diet might be
enriched with
.nitrogen, phosphorus, and magnesium to combine with excess
sulfur and
potassium to form compounds more easily assimilable by the
algae-bacteria
population.
Biological recirculation of substances advantageously combines
four
functions in a single process. 1) primary biomass synthesis, 2)
-reutilization
of raw waste, 3) primary purification of water, and 4)
regeneration of

PERIODICAL: "Astronomicheskiv Zhurnalli (Journal of

1957, Vol.34, No.2, pp. 205 - 205 (USSR).
ABSTRACT:
The open cluster NGC 6811 was photographed using the
15 inch Schmidt telescope of the Engelhardt Observatory.
A total of 16 photographs of the cluster was obtained
in addition to 12 photographs of standard areas. Stars
of Kapteyn a-rea 39 were used as Dhotographic standards.
In the treatment of observational data stellar
magnitudes were obtained in the International system
of photographic and pholovisual magnitudes. Mean
squgre errors were: + OT05 (photogrgphic magnitude),
� 0.05 (photovisual Magnitude), � 0.07 (colour index).
Photographic magnitudes obtained are in agreement with
ref.2. On the basis of the photographic and photo-
visual magnitudes of 357 stars distributed in -the
cluster and its neighbourhood diagrams of colour index
visual magnitude were constructed (Figs. 1 - 6)-for
six separate concentric zones. Fig.7 shows the
corresponding diagram for the firsu three zones taken
together * Fig,8 shows a photograph of the cluster.
As can be seen Figs. 1 - 6) the main sequence has a
clear outline only for the stars of the first three
zones. For higher zones background stars predominate.

The open stellar cluster NGC 6811. (Cont.) 502
For 19 stars of spectral class AG - Ag the mean value
CE = b'.10 was obtained. The distance was determined
as r = 1000 Parsee. (corrected for liLht absorption).
This is in good agreement with refs. 1 - 4. TLe
cluster is at an appreciable distance from the plane
of the Galaxy (z = +190 parsec.). The angular
diameter, derived from star counts, is 26", while the
linear diameter is 5.8 parsec. 11 figures, 5

in 1958 f-Ref 32. In the atlas the author has collected.all
published observation data for the colour-magnitude diagram;
that
explains some inhomogeneity (e.g. in the exactness). The
author
has used the papers of the following Soviet scientistst P.P.
Parenago r-Ref 5,37-7, T.S.Kirillova fRef 13__,7, and
T.A.Uranova
fRef 3~., . In order to compare the conformity with the law in
the spatial distribution of the open clusters with their
physical properties, the following three groups are separated
1. clusters with stars of the early spectral class 0 and B
often
combined with diffused nebula, 2. clusters containing only
stars

TEXT-, The stars belonging to the operi c1tister NGC 1605 were
investigated photometrically by K. A, Barkhatova and
Yu.A,,PL1pySheV
using the 15" Schmidt telescope at the Astronomical Observatory
imeni Engellhardt. Star counts showed that the NGC 1605 cluster
consists of approximately eighty stars The cluster has an
elongated form without any noticeable concentration towards the
centre, In projection the cluster resembles an ellipse rather
than a disc, the ratio of the sem-axes beint~ 1-J.5
(Fig,3) The
major axis of the ellipse is almost perpendicular to the plane
of
the Galaxy (Fig-3), The star No.21 (Fig,4) was taken as the
centre of the cluster in the star count The colour index -
apparent magnitude diagram was constrocted on the basis of the
photometric data, Table 1 on p.868 gives the photographic and
photovisual magnitudes and also the colour indices of the stars

est members of the cluster have an apparent photographic
magnitude
of 14m.5 and a colour index of + 0m 5 The unusual slope of the
main sequence may possibly be explained by the fact that for
the
majority of the faint stars their position on the diagram is
not
known with certainty. A more careful determination of the
stellar magnitudes and colour -indices will be necessary
before it
will be possible to state unequivocally that the unusual slope
is
in fact real,, The distance to the cluster was found to be
1480 pc and the angular diameter 7', It follows that the linear
diameter is 2.6 pc,, It is noted that the brightest members of
the clusters have magnitudes of 14111~5 so that the problem of
the
reality of the unusual slope of the main sequence will take
some
time to resolve, Acknowledgment-s are expressed to Sh T
