ABSTRACT: The vertical distribution of the tetWerature of the Intrinsic radiatiw-
of the atmosphere was measured at wavelengths 16-3, 2B.9, 21, and 30,6 cm in the
altitude range from 5 to 30'. The directivity patterns of the antenna system at
half-power level were 241, 301, 35'., and 4o,. The brightness temperatures of the
atmosphere were determined by comparing the antenna temperatures for sipmale fNa
the atmosphere with the discrete source Caosiopacia-A. The total absoi-ption
at the zenith could be determined from the measured and theoretical values of the
antenna temperature so a function of the altitude angles The total absorption in
the zenith direction was found to be 0,,66 db 115% ' for all temperaturesp come-

TEXT: New methods are proposed for: 1 - preliminary balancing
of a T-circuit consisting'of L and C by the simultaneous
application of short circuit and no-load conditions to individual
sections of the circuit; 2 - the connection and balancing of
an X-circuit of a capacitance bridge. After simultaneous
solution of the equations obtained for the different processes
of circuit balancing the first method may be used to obtain a
simple relationship between the measured impedances, the main
bridge parameters and a single "residual" parameter which in

easiLy calculated from the dimensions of the conductors. The
now X-circuJt capacitance bridge differs from usual capacitance
bridges in the method of connecting the object to be measured,
in the system of screening the bridge and the balancing arms,
in the balancing sequence and in the use of conductivity decades
tising elements of special construction (not wire wound).
The bridge can be balanced rapidly and can measure all three
p.,7-ameters in the frequency range up to some megacycles to an
accurncy of 0.01 to 11'. In addition, double X- and T-circuits
were investigated. The double X-circuit bridge can be used to
determine the parameters or a measured object in the form of a
quadripolo circuit.

TEXT: lit addition to their known advantages, silicon
rectifiers have good resistance to shock and vibration so that they
are particularly suitable for narrow-gauge rectifier locomotives
for timber haulage. -in 1960 TsNll~JE developed and made a narrow-
gauge electric locomotive type 3Y,'y 74-01 (EKOU-4-01) having
silicon rectifiers and meeting the requirements 3tipulated.for the
timber and peat industries. The locomotive power is 150 W, the
coupled weight 18 tons. In developing the locomotive the silicon
rectifiers were tested and recommendations were made to the factory
manufacturing the rectifiers. The following conclusions are drawn
from tests on silicon rectifiers type CJRK-100 (PVK-100)4

I ASTRAC71: The resistance of mice to typhoid bacteria and staphylococcus was
studie(- under conditions of decreased atmospheric pressure in a pressure chamber.
The animals were vaccinated with a chemical typhoid monovaccine (0-3 ml; 30 Pg of
j,iu,e antigen). Infection took place on the 10-12th day after vaccination. Presswe'
parameters were: "altitude"-4ooo m (75 m/sec) for 30 min; recovery-5 m/sec. It
was fouznd that resistance to typhoid and staphylococcus increased under these condi-
L~o.is; the viability of typhoid-infected mice was 1.99 times higher, while that of
;taphylozoccus-infected mice was 2.22 times higher than that cf the control - vroup (t ~a 3.1
.5, -espectively). The postvaccination immunity index (anti-typhoid) increased
5
to 1.99 times that of the control group (t a 4.1). To test the effectn of 02 partial

Pressixe on this plienomenon, 16 mice were placed in a ten-liter jar, through which
liumidified 02 was circulated at 0.4 liters/min for 15 min. Unvaccinated mice re-
ceive'l 02 only after infection, while vaccinated mice were exposed after vaccination
tL-,d infection. Oxygen saturation took place prior to "a3cent." This series showel
that _uring 0 inhalation, the resistance of the animals increased by 2.00-2-03
(t = 6.0-8.93. Postvac.-ination typhoid immunity was 1.99 times greater than that
of tht control group. The data showed that the immunological reactivity of mice ir~-
c-eased during decreased atmospheric pressure as well as during increased oxygen
saturation. However, exposure to oxygen prior to "ascent" apparently eliminated the
favorable effect of decreased atmospheric pressure on the immunological condition
of the organism. (WA-221

coaditic,txs we brought about by the following combination of treatments:
1) cu+.ti.-rg specimeas from the head portlon of the ingot along the rolling
length'in a direction perperAicular to the direction of the rouing;
2) prior ccmpression of the specimens by 10%; 3) aztificial aging at

ABSTRACT: The hardness and the ak (resilience) of killed open-hedrth MSt.3
steel of stardard composition were investigated after the steel had
been subjected to various forms of treatment while in a state of pre-
liminary overheating (normalization at 13500C for a period of 7 min),
as well as after normalization at 9201 which was cdrried out in order
to obtain different grain sizes, It was established that overheating
reduces the quantity of work required to fracture a specimen in an
impact test to a value of 19 kgm, the difference in properties of over-
heated and normal steel remaining practically unaffected by various
forms of heat treatment. Although, unlike fine-grained steel, the

tempering, woik hardening, and thermal aging, its mechanical properties ire
affected by strain aging to a greater degree. However, the displacement of the
upper threshold of cold shortness is identical in both cases. The effects of strain
aging are connected with processes of cold hardening: As the ductility diminisheti
during cold wor~.ing, the tendency toward brittleness during subsequent aging
increases.

heating (normalization at 13500C. for 7 minutes) the upper threshold of cold
shortness is 80* higher than in steel normalized at 9200. The energy absorb-
ed in the fracturing of the superheated steel In the pasty state was as lov
as 19 kilogram-meters, while in the case of specimens normalized at 9200 it
ex,-.eeded 30 kg-m. The sharp difference in the properties of superheated and

Author's conclusions: 1. Fbr purposes of analyzing the cooling process in quench-
1mg, it is possible to use the method of superimposing the cooling curves on
the themokinetic diagram. 2. The hardenability of a 40Xh-steel main shaft
for the transmission of the ZIL-150 automobile can be increased by interrupted
quenching in water, thus rendering oil quenching unnecessary. 3. The sug-
gested method of quenching permits full automation of the beat-treating process.

Engineer. Properties and Heat Treatment of Alloys for Elastic Elements of In-
strumente 65
A highly sensitive method was developed and a device designed for testing
the properties of metal diaphrn~gms for instruments. The dlaphragns tested
were made of beryllium bronze, phosphor bronze, and a high-alloy steel
(N36KhM) containing nickel, chrome, titanium, and aluminum. 'rests made
on the diaphragms after heat treatment showed that their properties depend
strongly on the temperature and length of aging, during which a decompoo-
ition of solid solutiona takee place. Aging Inemaces hardness ana the

-the temperature of aging. Hysteresis, residual deformations, and sag are at
their minimum approximately at those temperatures at which the propertieto as-
JOCiated with strength are most pronounced. Thus it is scenthat these prop-
arties of the diaphragms are linked with the structum of the alloys: the
higher the resistance to the development of microplastic deformations, the
smaller the degree of hysteresis. On the basis of theseTindings, certain
iwthods of heat treatment are recommended for diaphragms made of the alloys
specified above. 7here are 43 references, of which 25 are Soviet, 17 English,

Candidate of T~chnical Sciences. Change in MicroBtructure, Type of Fracture,
HarCmess, and Coercive Force of Steel in the Blue-brittle State 115
The authors' Investigations led to the following conclusions:
1. The change in the type of fracture of the specimens corresponds to the
change in toughness and plasticity in the blue-brittle temperature range.
At testing temperatures of 100-4000C., the fracture changes from coarsely
fibrous to finely fibrous. At 400* crystalline zones appear. At 525-5500 the
crystallin zones achieve their maximum extent, and the plane of fracture be-
comes 11stepped", as if laminated. At higher temperatures, the fracture
again becomes fibrous. 2. A microscopic study of crack distribution showed
that at 525-550* the fracture ordinarily takes place along the grain bound-
aries, but in tough specimens it is usually tran3crystalline. No substant-

ial difference in the structure of tough and brittle specicens was observed
at magnifications of UP to 1700 times. 3. The hardness of specimens that
were impact-teeted at blue-brittle temperatures and cooled to room temper-
ature was rather high as compared with specimens tested at lower temperatunis.
This indicates a certain residual brittleness caused by the impact test in
the 500-550* range. 4. Measurement of the coercive force of brittle and
tough specimens showed no numerical difference for specimens retaining some
brittleness after being heated in the blue-brittle range. Hence it is seen
that the development of blue brittleness is not accompanied by a decomposition
of solid solutions. 5. On the basis of the above, it would appear that the
marked lowering of plasticity caused by blue brittleness is associated with
a deformation process or with diffusion processes developing at elevated
temperatures in the boundary layers of the grains, which processes, however,
do not lead to the precipitation of dissolved constituents, but do cause
embrittlament of the grain boundaries. There are 3 references, all Soviet.
Arl:hipov, A.M., Candidate of Techiiical Sciences. 11eat Treatment for Improving
the Properties of Cast Iron Tleemed in Metal Molds 125
Author's conclusions: 1. Temper hardening is necessary for obtaining a
uniform structure along the cross section of the specimen, for increasing
hardness and wear resistance, and for improving the mechanical properties
of the cast iron. 2. Qxwnching results in an increase in hardness and a
Heat Treatment and Strength of Metals and Alloys (cont. ) 650
decrease in strength- 3. Tempering at a temperature of 350-450*C. results
in a uniform structure, decreased internal stresses, and miximm possible
tensile strength, together with reduced hardness. 4. Quenching of cast
iron teemed in metal molds is more effective than quenching of ordinary gray
iron, since in the former case the graphite inclusions, strongly affecting
the mechanical Iroperties, differ greatly in shape, size, and distribution
from those in ordinary gray iron. There are 5 referenzes, all Soviet.
Arkhipov, A.M., Candidate of Technical Sciences. Effect of Silicon Content
on the bbchanical Properties of Cast Iron Teemed in bbtal Molds 139
The author's investigation shows that the graphitizing action of silicon
in cast iron is at its maxim= when the silicon content is about 3 per-
cent. Five heats of gray iron were studied, the specimens differing
only in their silicon content (1-41%, 1.63%, 1.84%, 2.16%, and 2-37%)
and in the method of casting (in permanent metal molds and in loam molds).
Results showed that both tensile strength and hardness decreased as the
silicon content increased, regardless of the type of mold, but that the
tensile strength of the specimens cast in metal molds exceeded that of
those cast in loam molds by about 1.5 percent. A linear relationship be-
tveen tensile strength and silicon content was established, and an empir-
ical formula derived for calculating the tensile strength of a specivLan
of known silicon content. It was established that the chilled sitrface

The authors studied the effects of ultmsonic vibmtions on molten
metal cooling In the mold. Three cases were investigated, rawly, a
lead-antimony alloy, a zinc-tin alloy, and pure zinc. Vibrations of
180 kc/sec were emplDyw--d. In the first case a refined gmin structure
was produced; in the second, little effect was observed on either the
macrostructure or the picrostructure; and in the third case a non-
dendritic macrostructure resulted, in contrast to the dendritic macro-
structure of the untreated metal. There are 8 references, of which 7

tions 157
A new method is proposed for determining the energy dissipation in
the vibrations of a specimen fixed at one end in a teat stand designed
Card 10/ 12
Beat Treatment and Strength of ~btals and Alloys (Cont.) 650
by S.O. TsobkoIlo. The method is based on the determination of the path
of motion of the specimon. The authors obtain equations that give the
relationship between the elastic energy stored in the specimen, the ampli-
tude of vibmtions, the amount of energy dissipated, and the damping factor.
The equations farther account for the magnitude of working stresses im-
posed on the specimens and also determine energy dissipation per cycle,
which is not obtainable ordinarily with the damping factor alone. These
considerations, when applied to N361(hTYa steel, show that dissipated
energy per cycle as a function of stress loading rises with increased
stress, which is explained as the effect of microplastic deformation. At
the time, the higher the resistance of the metal to small plastic
deformations, i.e., the higher the elastic limit, the smaller the dis-
sipation increment. In particular, minimum values for the dissipation
increment and its rate-of increase are observed in specimens tested after
hardening from a tempemtum of 950*C. and aging at 7000 for 2 hours,
when their elastic limit is at its maximum. There are 3 references, all
Soviet.
