The authors, assisted by S.V. Natandon in the evaluation of
their research results, T.D. Rybnikova, G.F. Kurepina and
B.G. Varshaver in the experimental part of their investiga-
tions, and V.V. Durmashkina in the synthesis of some colorants,
investigated the photographical properties and absorption
spectra in the emulsion of a series of symmetrical (no sub-
stitution in chain) carbocyanines with different heterocyclic
residues containing methyl, ethyl or higher a~lkyl groups in
nitrogen atoms. The absorption spectra were measured with
an SF-2 spectropbotometer, the sensibilized plates were ex-
posed in the GOI (TSP-73) spectrosensitometer and developed
.in Chibisov's developer. Contrary to date auoted in litera-
ture, the methylptes and ethylates of . several colorants with

residues of indolenine, thiazoline, benzimidazole and thio-
diazole do not differ with respect to sensibilization action,
-while in the cases of this-, oxa-, and chihocarbocyanines,
the N.Nl-dimethyl derivatives are actually considerably less
effective as compared with the ethyl derivatives. As far as
the character of the sensibilization spectra, fogging and
desensibilization action, and the magnitude of the basicity
are concerned, the methylates of all investigated carbocya-
nines are very close to the corresponding etbylates. As
compared with the ethylates, the methylates of those carbo-
cyanines which - contrary to the ethyl derivatives - are ad-
sorbed to the emulsion microcrystals (mainly in the N-con-
dition), have considerably less sensibilization action. These
conditions usually have such a feeble photochemical activity
that the corresponding bands do not appear in the sensiti-
zation spectra. In a series of 1,11-dialkyl-3,3,3',31-tetra-

ABSTRACT: The isoaterism of the groups -GH-CH- and -S- is well known for
the thiazole- and pyridine derivatives4 It was very interesting
to observe the degree of isosterism of these groups in the series
of the benzthiazole- and thiophene-ti.iazole which have a hetero-
cyclic basis with condensed rings of thiazole and thiophene. In
order to obtain the substance mentioned in the title the thio-
acetyl, derivative of the a-aminothiophene which was then oxidized
by means of iron-ferricyanide was used as a starting point. The
first attempts of a synthesis of the substance in question failed.
A crystalline dis -1080 (1) was
ulfide with a melting point of 107
formed. The substance in question was obtained with a yield of
10% of the theoretically possible be-side the mentioned disulfide
only after the addition of the 2-thioacetyl-amino-thiophene
solution in a NaOH aqueous solution to a diluted iron ferricyanide
Cat;d- 1 /2- solution. The obtained base is a colorless oil which gradually

several constants of the 2-methyl-4,5-thiophene (21,31) thiazole
and of the 2-methyl benzthiazole as well as of their derivatives
are rather similar. There are I table and 9 references, 2 of
which are Soviet.

ABSTRACT: The authors measured (at 250) the dipole moments of some hemi-
oxanines containing 3-ethylrhodanine groups and indandione
groups by the heterodyne method in benzene. A table gives the
formulae, the-upper and the lower limiting values of the measur-
ed concentrations, the total polarization, the electron polari-
zation, the values of the dipole moments in Debye (Debaye)
units, and the position of the maximum of absorption of the
solutions of some pigments in alcohol (A max ). According to
experimental results, compounds which differ only by the length
of the polymethine group, have very dif f erEnt moments. An increase

Various results are then given and discussed. Although the
moment of indandione (1,3 2,72 D is greater than that of
3-ethyl-rhodanine (1,75 X the moments of the monomethine-
hemioxanines have a noticeably lower value for the derivatives
of indandione (1,3). This is probably, caused by the different
directions of the moments in 3-ethylrhodanine and indandione.
The variations of the investigated absorption spectra of the
hemioxanines, which are caused by an elongation of their poly-
methine chain, agree with the conclusions concerning the
structure of these compounds which were drawn from the inves-
tigation of their dipole moments. There are 1 table and 13
references, 5 of which are Soviet.

AB,Q,TRACT: 5,51-Dimethoxycyanines containing free or substituted
aminogroups in 6,61-potitions (as well as 6,61-amino-
derivatives) were synthesized in order to study batho-
chromic shifts in absorption maxima caused by Introduc-
tion of substituents into the chromophore. The following
intermediates were synthesized: 2-methyl-6-p-toluene-
sulfamylaminobenzothiazole (I) (by heating 2-methyl-6-
aminobenzothiazole with p-toluenesulfonyl chloride in
pyridine and subsequent addition of dilute HC1) (mp 209-

It can be seen that Introduction of' methoxy groups In
5,51-posItion of' the 6,61-d.Lsub9tituted thiacarbo-
cyanines, containin free or substituted amino groups,
causes an additive ~close to the calculated value)
bathochromic shift of the absorption maximum in all
cases, except fop 6,61-bl.9(dimethylamino) derivatives.
This abnormality Is explained by the appearance of
steric hindrance to the planar arrangement of the
molecule (the planar arrangement is required by the
unsaturation between the nitrogen and carbon atoms--
> N+=C< ) upon introduction of the two methyl groups
(see Fig. 1).

of the spectra of sensitization and absorption on the silver halide of non-polymer-
izable dyes does not change in the presence of color components. In a number of
polymerizable dyes the character of the absorption spectra of component stable
compounds considerably varies owing both to the main desorption of various polymo-
lecular states and to the redistribution of aggregate states in the adsorption
layer. In the case of component stable sensitizers these changes are, as a rule,
small. The authors assume that the increase of the sensitizing action of certain
dyes in.the presence of non-diffusing components, and also of a number of other
surface active substances, may be explained by the elimination, from the surface-
of the silver halide, of ions or compounds that render difficult transmission of
.energy from the sensitizer to the silver halide lattice, or by the fact that the
orientation of the dye molecules in the adsorption layer is favorable to the proc-
ess of transmission of the absorbed energy. There are 18 references.

The morphological substrate of the periocular reflex was studied in its peripheral
component during an experimental increase in intraocular pressure. Several
series of experiments were conducted on rabbits, with ligation of 3 venae vorti-
ce3ae on one side. On the side of the operation, an increase in intraocular press-
ui e of up to 45 mm. was regularly observed immediately after the operation, and
of up to 39 mm.. and over, on the other side. After 2-5 days the intraocular
pressure approached the initial value. Local changes consisted in oedema of the
eyelids, ehemosis of the bulbar conjunctiva, and lacrimation. Desquamation of the
epithelium and corneal oparity were also observed, as well as in some cases, peri-
pheral corneal ulcers with vascularization of the cornea. Manifestations of stasis,
congestion of the Umbus, and of the whole uveal tract, and hyperaemia of the
retinal vessels were present. The following was also established: an increase in
vascular permeability with exudation of the plasma and of the formed elements of
the blood Into the tissues; haemorrhages from the vessels of the ciliary processes
into the tric, choroid, and the perichoroidal space. In the region of the limbus
varicosities were revealed, fibrillary degeneration of the nerve fibres, and swell-
ing of tfie neuroplasm. In the cornea, Isolated fragments of larger nerve trunks
were found; in the region of dilated vessels of the uveal tract: oedema, varicosi-
ties, vacuolization, tortuosity, non-uniform staining. Degenerative changes such
as argentophilla, varicosities, and non-uniform staining were observed in the
layer of nerve fibres of the retina. Analogous vascular and nervous changes were
noted in the other (intact) eye. References 13. Kulikova - Moscow

ABSTRACT: In Ref 1, which deals with flows at high Reynolds
numbers when the viscous forces may be neglected,
a method of determining the resistance coefficients of
diaphragms was developed, it being based on the
relation between the pzessure losses and the
coefficient of contraction (c) of the stream.
Experiments show an excellent agreement with this
method. Hahnemann (Ref 3) extended this method to
other types of local resistance. Again experimental
results agree well with the theory. At very small
Reynolds numbers the viscous forces are most
important and the inertia forces may, in turn, be
Card 1/7 neglected. For the laminar steady flow of a viscouo

SOV/147-59-2-12/20
On the Influence of the Reynolds Numbers on the Magnitude
of the ResJ-ata-np-CnA--fflclents.-ol-..Diaphriagm -
incompressible fluid the coefficient of resistance is
given by Eq (1), the'magnitude of the constant A
depending only on the type of the local resistance.
Wuest (Ref 4) developed a theoretical relation (Eq 2)
for the pressure loss in a jet issuing from a circular
orifice and this relation will be used to determine
the constant A of Eq (1) by relating Eq (2) with
Weisbach formula (Eq 3) which results in Eq (4).
In the intermediate range of Reynolds numbers when
both inertia and viscous forces must be taken into
account the theoretical approach is more difficult.
There are, however, many practical cases (e.g.hydraulic
systems with organic mixtures of a high viscosity
coefficient, lubrication conduits etc) which fall
within this range of Reynolds numbers so that It is
important to know the resistance coefficients for
these cases. This was the object of the investigations
presented in this paper. The experiments were
carried out for ll,(Re,,~10,000 and the diaphragms

I - reservoir; 2 - H 111-11 pump; 3 - pump 623;
4 - return valve; 5 - safety valve; 6 - tap;
7 - hydraulic accumulator; 8 - pressure gauge;
9 - thermometer; 10 differential manometer;
11 - flowmeter; 12 filter. Experiments were
carried out on the hydraulic mixture AMG-10; to
increase the viscosity the fluid was thickened by
additives and to decrease the viscosity some kerosene
was added. In this way viscosity was varied from 3 to
50 centistokes at the temperature of 20OC; Pinkevich
v1scosimeter was used to measure viscosity. The actual
measuring procedure was as follows: two identical
portions of the piping were accurately calibrated and
then in one of them the local resistance was introduced.
By taking simultaneously the pressure drops in the two
portions by means of manometers the local resistance
was obtained directly as the difference between the two
Card 3/7 readings. Large pressure differences were measured

using mercury and for small pressure differences
the set-up shown in Fig 2 was used. In this
arrangement the fluid used for the experiments was
employed in the manometer and the pressure was
transmitted by means of the air supplied by the air
containers shown in the figure. The total pressure
difference between the points A and B is the sum
of the two readings hl and h2, For extremely small
pressure differences (of the order of 0.00, kg/cm2)
the two containers were made adjustable so that h2
could be made zero. Fig 3 shown the results of these
experiments. It is seen that for small Reynolds
numbers the flow is fully laminar, i.e. S is directly
proportional to Re (and therefore to the velocity of
the flow) but the coefficient A increases as
n SAIST decreases. This iast relation Is given by
Eq (7). Purely laminar flow ends when a critical
value of Reynolds number, as given by Eq (8), Is

line) with the theoretical values according to
Alltnhull' and with the results of TsAGI. In the
Intermediate range of Reynolds numbers the relation
between 19 and n as well as Re is a complex one.
When n in mmall the transition from the purely
laminar flow line to the turbulent flow line is smooth
at both ends of the graph but for larger values of n
the latter transition is sudden a-ad rapid, as shown
in Fig 3. Eq (9) and (10) give some relations for
the square areas for the flow through diaphragms.
For flows through a valve Rowley (Ref 5) found
TKB = 12-5- Hence combining the two, we get for this
case A 220; Recr = 9. The broken line in Fig 3
shows '40 f(Re) for the valve based on the above
relations and on the experimental data of Ref 5. The
two portions of the graph meet perfectly. In practice
it may be convenient to represent the local resistance

pipe as given by Eq (11.), where d is the pipe
diameter and X is a coefficient to be determined
experimentally. Fig 4 shows this relation for
various diaphragms. If the Reynolds number is based
on the velocity of the flow through the diaphragm
and on its diameter (Eq 12) then Eq (13) gives the
coefficient of resistance and its variation with Re
is shown in Fig 5. The following conclusions then
holdi 1) For small Reynolds numbers ~A does not
depend on the amount of opening of the diaphragm and
is given by Eq (14). 2) As Reynolds number increases,
the larger the opening of the d-taphragm the larger is
the Reynolds number for which the flow ceases to be
laminar. 3) For very large Reynolds numbers;A does
not depend on Re only on -the amount of opening of the
diaphragm. The graph is similar to that obtained by
Nik-uradze thus showing the similarity of flows in

TEXT: The author describes a battery pocket gamma-detector for the dell%sc-
tion of gamma radiation and the approximate rating of the dose rate with the
range from the natural background and up to some micro-roentgen per second. Two
gas discharge tubes (either MH-5 QIN-5) or KTX -90 (M'Kh-90) are used as indica-
tors, one of whioh is put In series with the radiation counter, the other at the
output of the RC-filter, connected ti parallel to the load resistor of the-countm
The device is calibrated with the aid of the gamma source by compiling a table
of relation between the dose rate (in micro-roentgerv Isecond) and the number of
flashes of the neon gas discharge tubes. There Is one circuit. F. A. K.

TITLE, Angular distribution of P-radiation from thick sources
PERIODICAL: Atomnaya energiya, v. 12, no. 1, 1962, 53-54
TEXT: The method of thick sources is widely used for determining specific
activity, to which the 0-yield is proportional for emitters whose thickness
exceeds the P-particle range. The angular distribution of the P-radiation
must be known. It was investigated by measuring the absorption and
scattering of P-particles from a point source in an absorber. The source
was placed betwee-.. - thick backing and foils of different thicknesses.
The absorbers (backing and foil) were made of Al, Cu, Zn and Pb.
Measurements were made at a relative solid angle of &) - 4-7-jo-4 in a
vacuum chamber, by means of an end-window counter type T-25 66J1 (T-25 BFL)
Backing and foils were mounted on a rotary frame on the axis of which was
the point source. Not more than 1.5 % of the scattered radiation hit the
counter window. From the P-flux N 9(t) thus measured the P-Yield n. from
the surface of, a thick source was calculated by graphical integration of
