ABSTRACT: To determine the specific-heat of*electrolytic alkalis,
the method of direct'heating with an isothermic cover
for the calorimeter Was used. The paper describes the
experimental equipment.and the measuring methods. The
following .1 solut-ibns were investigated: NaOH, NaCl,
Na2CO3, NaC103, Fe (natural) and 804 in..weak, average
and strong concentrations. Tests were carried out in
the temperature range 40 - 1000C. The accuracy of
empirical data was checked, and it emerged that the

specific heat values for any iven temperature were
obtained with strong alkalis ~42.60G - 101.170C, 0.785
- 0.806) which have the largest NaOH content and the
smallest NaCl-content. The largest specific heat
values were found with the average alkalis (42.00C -
100.40C, 0.850 - 0.874); the weak alkalis despite a
considerable drop in the NaOH content in the solution
compared to average'electrolytes, had lower specific
heat values (41.80C - 100.60C, 0.821 _0.845) (The
values for specific heat are expressed in cal~/kgOC.)
This is explained by the fact that in weak alkalis
the NaCl content is considerably higher than in the
average ones. There are Z sectional diagrams,
tables and ~2 Soviet references.

TEXT: The authors study the possibility of drawing the temperature
curve of viscosity according to one value for the distilled fuels now
in use. The petroleum products used in the experimental investigation
of viscosity are listed. The kinematic viscosity was measured in the
temperature range between 20 and 1600C. A visoosimeter of the Pinkevich
typp.was used. A correction was introduced for the kinetic fluid energy
and for the temperature-dependent expansion of the viscosimeter glass
(Ref. 3). With the use of the reduced parameters, the data obtained
were joined to a curve-. V* = V/90.65 and.t - T/Tm. V is the kinematic

TITLE: The Use of the Similarity Method in the Study of Liquid
Viscous Fuels\\
PERIODICAL: Inzhonerno-fizicheakiy zhurnal, 1960, Vol. 3, No. 9,
PP- 56-60
TEXT; By making use of the.mathematical theory of similarity the author
developed a method of estimating-the temperature-dependence of the vis-
cosity of viscous liquid fuels. The method is applicable to ranges far
from the critical point (where density is a linear function of temperature).
On the strength of density measurements, relations Q1Qo = T(T) as well
as V/Vo.=1V(,r) are obtained, from which, using data relating to similar
fuels, conclusions are drawn as to the properties of the test fuel.
ip(T) is a universal function of the similar substances, v is the

The Use of the Similarity Method in the Study S/170/60/003/009/008/020
of Liquid Viscous Fuels B019/BO60
The application of the authorts method to eight technical petroleum fuels
and fractional mixtures (Table 1) was checked by a comparison with ex-
perimentally determined dependencies of density and viscosity on tempera-
ture.(Fig. 1). Based on the data 'a relation in reduced parameters Is
obtained, which holds for all similar substances of this type (Fig. 2).
Data on viscosity obtained by the density determination described, were
found to be more accurate than those obtained by the direct measurement
of viscosity. Thus the method described here permits the temperaturede-
pendence to be determined from a density measurement of the substance
concerned, whenever data are available for a similar liquid. The author
thanks Professor P. D. Lebedev and Docent T. A. Kolach. for their valuable
aid. There are 2 figures, I table, and 4 references. 2 Soviet, I German,

TITLE: Intrinsic,.magnetic flux in a superconducting solenoid
SOURCE: AN SSSR. Doklady, V. 169, no. 3, 1966, 569-572
TOPIC TAGS: solenoid, superconductivity
'ABSTRACT: -A new method is proposed for studying the magnetic properties of a supercon-
ducting solenoid in view of the incomplete and contradictory picture of the behavior
of a solenoid in a self-field. The magnetic history of the solenoid may be described
by using the concept of the total magnetic flux (magnetic linkage) of the solenoid T.
This quantity is the sum of the intrinsic T. and extrinsic 7 fluxes of the solenoid.
e
In an Infinite solenoid the extrinsic flux is independent of the intensity of magneti-
zation in the coil and is linearly dependdnt on the current I flowing in the coil,
Te=LeI, where Le is a proportionality factor which may be called the extrinsic induc-
tance of the solenoid. It is found that the factor L for a solenoid of finite length

may be selected so that only the change in extrinsic flux V must be consi.dered,when
e
the distribution of magnetic induction within the superconductive material is constant.
The proportionality factor Le is taken as (d'Y / dl) 1-o for a solenoid without a magne-
tic history. Thus for the case where the coil is completely diamagnetic and there is
clearly no magnetic flux within the material, d1l' / di =~ d'V,, / dI and dFj / dI = 0, 1. e.
the change in magnetic linkage is due to the change in the extrinsic flux. Three ex-
perimental solenoids are used for istudying the magnetic behavior f jole \ id in terms

Abstract: When there was Rttle Insect infestation (5-10
insects per 1 m ) treatment of seeds with granozan
(100-150 g/c) before planting was recommended.
In an infestation with wire-shaped Insects (more
than 10 insects on 1 m2) the most effective treat-
ment was the introduction of HCCH into the soil
before cultivation (100 kg/hectare of a 12% dust).
The administration of HCCH into maize (6-8 kg/
hectare) was economically advantageous. When the
maize sprouts, planted without treating the soil
and the seeds, were discovered to be damaged, dust-
ing (200 ml to a cluster) with a 0.3% suspension
of a 12% HCCH.dust was needed on the manure ferti-
lizer.

ABSTRACT: Results of an experimental investigation conducted on an SVK-150
turbine are presented. It was found that silicate deposits readil-y emerge from
the turbine steam ath on an abrupt load drop accompanied by a corresponding
p
reduction of the stage steam pressure. Experiments under such conditions
showed that silicic-acid concentration in the outlets of high-pressure and
medium-pressure casings was as high as 10-25 mg/kg, while its concentration

SOV/112-59-5-8563
Investigation of Salt and Silicate Behavior in the SVK-150 Turbine Steam Path, . . . .
in the inlet steam was 0. 05-0. Z mg/kg. As the load was increased up to its
rated value, the silicic acid drag-out from the turbine stopped. The silicic
acid evolved from the high-pressure casing was deposited in, reheaters. The
silicic acid is deposited on the turbine blades predominantly in a slightly water-
soluble.form. The drag-out of silicate deposits from the turbine steam path on
an abrupt load drop can be explained by different expansion coefficients of the
metal and the deposit; when the steam temperature changes, the deposit cracks
and peels off the blade surface. To prevent silicate -deposit formation, the
permissible silicic-acid concentration in the steam should not exceed 0. 0 15
mg/kg.

TITLE: An Erroneous ~_-eatment of the Nature of Selective Carry-Over
of Silica by Steam
PMIODICAL: Teploenergetika 1959, Nr 8, pp 51-53 (USSR)
ABSTRACT: This-article is a critical analysis of an article by G.M.
Ivanova published in Teploenergetika Nr 7, 1957. There is
plenty of experimental evidence that all the modifications
of silica (Si 02) are soluble in steam. Depending on the
conditions, the reaction may follow either the formula
given in equation (1) or that in equation (2). Figures
are given for the differen
tial heat of dissolution of
'
amorphous silica and betaquartz, and the difference between
the figures is close to the latent heat of fusion of quartz
,
which confirms the acourac .y of the results. In EL b0iier
silica enters the steam by dropwis,e oarry-over as well as
by evaporation, but simple calculations show that the silica
transfer by solution in.the steam is much greater than that
by dropwise carry over. Ivanova's conclusion that silisa
Cardl/3 cannot dissolve in the steam is erroneous. The relative

SOV/96-59-8-14/27
An Erroneous Treatment of the Nature of Selective Carry-Over of
Silica by Steam
magnitude of dropwise and selective carry-over in Ivanova's
experiments may be judged from the graphs in Fig 2, which
.are constructed from the data tabulated in Ivanova's ar-
tiole. In these graphs the coefficient of silica carry-
over is plotted as function of the alkaline number of the
water in the clean section of the boiler. The lower curve
oorresponds very closely to the coefficient of selective
carry.-over of silica by steam: obtained in tests at the
Central Boiler Turbine Institute in 1950. Therefore, silica
,carry-over corresponding to the lower curve may be aitri-
buted to dissolution of silica in the steam. Ivanova also
asserts that the relationship between the silica content
of the steam and the silica content of the boiler water -i's
identical with that between the wetness of the steam and
the salt content of the boiler water during dropwise carry-
over. This is not very convincing, because the experimental
points lie approximately round a straight line, as shown in
Fig 3. Some of Ivanova's less Important conclusions ~re
Card 2/3 also of doubtful validity. It is concluded that Ivaaova7s

SOV/96-59-8-14/2?
An Erroneous Treatment of the Nature of Selective Carry-Over of

assertion that selective carry-over of silica is dropwise
is unfounded; the data quoted In support of this idea are un--'
convincing and if correctly interpreted lead to the opposite
oonolusion. There are 3 figures and 1 Soviet reference.

steam. (0 prirode unosa kremniyevoy ki:iloty parom vysokogo davleniya)
PEkIODICAL: Teploenergetika, 19582 No.6. lip. 16 - 20. (USSR)
AASTRAM Silicio aoid carryr~over by steam has Wen explained in many
different irays, because it is a complicated phenomenon. Silioic
acid exists in aqueous solution in many different form , including
zolloidal; in boiler-water, it is in equilibrium with its alkali
salts. If the boiler water is alkaline, the siliza is present in the
water as sodium silicate and in the steam as silicic acids the
difference is not revealed by the usual chemical analysis, and the
amount of carry-over depends on the p1l value of the water as well as
on the ratio of the Si02 in the steam. to that in the water. When the
pH value is about 7, which corresponds to free sili-tit aoid, the
carry-over coefficient is equal to the ratio of the Si02 contents of
steam and water. In high-pressure boilers, where the pH is not less
than 10, polymerisation of S102 is hardly possible and the compound
is in true solution so that no allowaure need by made for its
polymerisation. This is confirmed by previous work on the solubilitY
of different forms Of Si02, plotted in fig.2. in the light of thief
and of the laws of phase equilibrium and distribution of substances

between phasest it was possible to unify all the experimental data
on carry-over Of Si02 by saturated stem with data on the solubility
of SiO2 in water and superheated steam, and to draw up a complete
diagram of state of the system Si02-H20- For this tw3-phase system,
the coefficient of distribution Of S102 between phases is a function
only of pressure; the corresponding relationship is plotted in fig.3.
This graph also includes curves for other substances found in boiler-
water. Graphs of the solubility of Si02 in superheated stem are
plotted in fig.4; a corresponding foraula is given, the values of its
constants being indicated in tables 2 and 3. SiO2 solubility figures
calculated from the above were in good agreement with experimental
results over the pressure range 120 - 185 atma., determined in a power
station. The complete diagram of state of the system Si%-E~' is
plotted in figs.5 and 6. The upper boundary line gives the solubility
of quartz in boiling water at the correapouding pressure. The lower
boundary line indicates the solubility of quartz in saturated steam
in equilibrium with a boiling saturated solut3on of SiO2. The critical
point for SiO2 solution is only 0.20C above that for pure water. To
the right of the saturation line is the region of equilibrium tetween
