ABSTRACT: The author describes his method for measuring the optical
densities of spectrosensitograms, in determining the spectral
photosensitivity of photographic materials by the GOI system.
An 1&-4 recording microphotometer is used and the modification
consists in alterations to the method of processing the results.
This reduces the time required by 2-3 times and gives greater
accuracy. The result is a curve showing the spectral photosen-
sitivity of the film or plate, and by the same method character-
istic curves for different values of the light wavelength can be

TEXT: The dispersion equation is derived for this case and
compared with the n-th propagation resonance. The form of the
wave spectrum is shown graphically for two values of u where
u = 1'rHa/c (wH is the gyrofrequency, a is the radius of the
spiral), indicating the rogions where slow and fast waves are
propagated and also the regions of no propagation. Dispersion
curves are obtained by graphical analysis before and after
resonance for the case when the direction of wave propagation
coincides with the direction of the magnetic field and also the
converse of this. The direction of the magnetic field
influences the phase velocity of the waves. The distribution of
the flux density for various types of waves is calculated using
the usual expression for flux density of monochromatic waves

along the z axis. As there is strong dispersion in this
particular system the results are only qualitative and, in order
to obtain more accurate results, it is necessary to use the quasi-
monochromatic approximation. The calculation shows that most of
the wave propagation occurs inside the spiral (in the ferrite).
This is in agreement with the fact that the phase velocity of
these waves is cnly very weakly dependent on ctg 9. For the
usual slow waves a large part of the flux distribution is outside
the spiral. There are 3 figures.

ABSTRACT: The strength and ductility of polycrystalline ammonia are studied as func-
tions of temperature under unilateral pressure. Cylindrical specimens 10 mm in dia-
meter and 40 mm, long with uniform microstructure and polished ends,were studied at
temperatures from 77 to 1600K. Curves are given for the breaking point, limit of
proportionality and relative compression as functions of temperature. These data
show that crystalline ammonia ho extremely low strength properties and ductility.
Solid ammonia is quite hrittlelat the temperature of liquid nitrogen and sbows elas-
tic deformation right up to the breaking point. At stresses of 0.5-0.6 kg/MM2,cracks
are formed parallel to the axis of the specimen with an accompanying characteristic

sound and a slight reduction in loading (up to 100 g). The final breaking stre
IvO.8 kg/MM2 remains constant throughout the experimental temperature range. At
point there is an instantaneous reduction in loading to zero and the specimen is
shattered. The shape of the fragments and the slight degree of deformation before
the breaking point show that cleavage is the mechanism responsible for fracture of
ammonia crystals between 77 and 1300K. Above 1300K (0.6 T ), the ductility of the
specimens increases and creep is observed under a constantmload. Shearing is respon-
sible for fracture above this point since cleavage strength remains nearly constant
with temperature, while an increase in temperature causes a considerable reduction
in shearing strength. The relationship between rate of uniform creep V and stress a
is V=Aan , where A and n are constants equal to 500 and 5 respectively at 1600K and
stresses greater than the limit of proportionality. The energy of creep activation
is found to be 5.6 Kcal/mol. This is approximately 10% lower than the heat of sub-
limation for solid ammonia. Orig. art. has: 3 figures.

ABSTRACT: The article is devoted to a study of aluminum4acuum
condensates obtained by vaporization of the metal-Ci6i-crucibles
made of alundum and berylliu; oxide. Aluminum and its loys were
vaporized in a vacuum of 10-D mm Hg. The condensates we..-O formed
on polished and carefully cleaned open steel rings, located co-
axially with the crucible at a distance of 80 mm. A temperature
gradient Of 50-55000 was created by heating one end of the ring
and cooling the other. The thickness of the condensate film was
approximately 40 microns. Vaporization of aluminum from alundum

crucibles at 120000 was accompanied by the reaction of the material
of the crucible with the molten aluminum. At the end of 3-4 hours
-there was formed a solid solution 1.5 mm thick on the walls of the
crucible. In this, the amount of the alloying aluminum oxide was
evaluated at from 8 to 10%. oIt was found that at a condensation
temperature greater than 450 , the aluminum oxide In the condensate
Is formed in the Crystalline state of gamma aluminum oxide; at
.lower temperatures, In an amorphous or subdispersad state. Aluminum
oxide increases considerabli the microhardness of ths aluminum
condensate (UP to 330 krjmm, ). Annealing at 230-490 has the
opposite effect. Samples condensed at temperatures of 450-5200
do not recrystallize during annealing. Condensates of a multi-
component alloy of aluminum, copper, magnesium, manganese, silicon,
and iron, based on aluminum reinforced with aluminum oxide, have
.considerable strength (50-60 kg/mm;j-) and greater ductility than
Condensates of aluminum obtained under analogous conditions. Orig.-

TOPIC TAGS: ammonia, temperature dependence,, elastic modulus,
elastie'deformation, creep mechanism, stress relaxation
ABSTRACT: The authors used earlIer compression-test data (rJTT V. 7
!'27892 1965) to determine the static modulus of normal elasticity of I
i polycrystalline ammonia in the tuem~erature interval 77 160K. %I In -
_-asmuch as at T > 110K a great reduction is observed in the 11m-i of
roportionality of ammonia, making measurements on the deformation
P
curve difficult, they made use of the fact that the proportionality
.limit can be increased by prior deformation of the samples. Conse

quently the values of the modulus 'of normal elasticity were deter-
mined from the second-deformation curves the accuracy was 7 Per
cent. A plot of the temperature variation of the modulus of elas-
ticity shows that the values of the dynamic modulus of normal
elasticity differ little from the static modulus determined by the
tween
static method. With increasing temperature., the difference be
the two increases from 14 per cent at 77K to 21 per cent at 160K.,~
owing to the Increased role of th e relaxation processes and creep
processes upon deformation of the crystalline ammonia. From the
-shear modulus of the crystalline ammonia, it is estimated that its
theoretical strength is -10 kg/6ni by comparison with theearlier
results it is concluded that the strength of the investigated
Polyarystalline ammonia was 15 times lower than theoretical. Orig.

high temperatures (up to 15000) is suggested. The powder of the.
substance to be investigated is applied on to a platinum Y'rire of
about 0.2 mm diameter. The suitable temperature is maintained by
allowing the current to pass through this wire. The device con-
sists of two suitably shaped brass plates, which are connected by
a shaft. Between these plates a platinum wire is dra%yn in such a
manner that one of its ends is made fast and the other is connected
to a movable rod vrith a spring. This rod rests in two bearings of
insulation material. The current is fed by 2 elastic lines in such
a manner that one of them is connected to the connecting shaft of
the device and the other to the free end of the movable rod; for
Card 1/2 reascns of safety this line is caught by an insulator which is

steel rod in such a manner that the axis of this rod and that of
the platinum vrlre is the same, The rod servea as a holder for the
device with the sample and is fastened in the X-ray camera acrord-
ingly. Because of the automatic control of the necessar-j current
a current stabilizer, an autotransformer, and a step-daan -*1.ran---

A13STRACT: The authors study some of the electrical properties and the structure as
well as paramagnetic resonance absorption of polycrystalline barium titanate with
small admixtures of oxides of trivalent elements. Preparation of the specimens is
breifly described together with an explanation of the experimental methods and equip-
ment -used. Paramagnetic resonance absorption was measured at 9320 Mc and 781K. It
is experimentally established that there are four possible types of solid solutions
in BaTi03-R203 systems. 1. A solid solution of substitution in the barium ion sub-
lattice with the formation of weakly bound electrons (donor levels)

Solid solutions of this type have high electrical conductivity. 2. A solid solution
of substitution with subtraction In the barium ion sublattice
in this case, the lattice is neutral due to barium vacancies, and the specimens are
dielectrics. 3. A solid solution of substitution in the titanium sublattice
where it is most natural to assume that electri-a neutrality of the lattice in the
case of oxide semiconductors is due to oxygen vacancies formed during annealing, and
electrical conductivity does not increase. 4. A more complex solid solution of sub-
stitution in both sublattices with the formation of oxygen vacancies and donor levels

and in table 3 for synthesized wollastonite. Table 1 shows the
dependence of the inclination tangent of the dielectric losses on
the burning temperature of the raw materials. Figures 2-5 show
microphotographs of wollastonite rocks and synthesized wollastonite,
while figures 6-8 show X-ray pictures of these viollastoniteo.
Furthermore, the electric and physico-mechanical properties of
radioceramic materials made of wollastonite are given. Figure Q,
represents the results of comparative examinations of the hcat
resistance of samples of steatite material and wollastonite.
As can be seen from these results$ the heat resistance of the
wollastonite samples is much higher. Investigations showed that
the wollastonite rocks from the Kansay and Lyangar deposits can'he
used as a raw material for the production of electrotechnical and
other types of ceramics. There are 9 figures and 3 references,

ABSTRACT: The existence of the 6-modification of magnesium metasilicate
has been discovered by the thermal decomposition of ta2c.
Investigations of the X-ray structure have shown that the
6-phase distinguishes distinctly from protoenstatite. The
existence of 6-]AgSiO 3 has been confirmed by comparative in-
vestigations of the refraction indices, the density and the
mechanical stability of the various modifications. The thermo.-
dynamical stability of the 6-phase was investigated at 9000.
In the absence of mineralizers the 5-phase is stable up to
14000C. The 6-modification of MgSiO 3 can be used for the
production of non-aging steatite. There are 3 figures,

ABSTRACT: As is known, the fundamental properties of piezoelectrics
are correlated with the spontaneous nelarization within
the temperature-range below Curie point. It follows from
the conditions of thermodynamic equilibrium that the die=
lectric constant in the Curie point corresponding to the
phase transition attains very high (theoretically infinite).
There is, however, a possibility of increasing the dielec=
Card 1/4 tric constant of the solid dielectrics at the expense of

relaxation ionization which is caused by the relatively
marked displacement of the ions and which is not correla=
ted with the phase transition at Curie point. The combina=
tion of the considerable ion displacements with a local
field favorable to polarization in the lattice of the type
11perovskite" may result in an excessively high dielectric
constant without piezoelectric properties. The experimentally
found values show that the loosening of the lattice of the
type "perovskite" (strontium titanate, solid solutions of
strontium titanate and lead-titanate, barium titanate) by
means of a part-substitution of the bivalent cations by ca=
tions of high valence (bismuth, cerium) without structural
change and with low conductivity results really in an im=
portant increase of the dielectric constant (up to several
thousands). The dependence of the E and of tg5 on the tem=
perature apparently indicates the relaxation character of
polarization. The elaboration of the experimental values by

makes it possible to estimate a aeries of values charac=
terizing the process of polarization. Results show that
the fundanental hypothesis agrees with the experimentally
obtained data and that it is not contrary to the phenome=
nological theory. The substitution of the bivalent cations
in the lattice of the type of "parovskite" by cations of
high valence leads to the formation of solid solutions of
the deduction type. In this case it follows from the con=
dition of the electric neutrality of the lattice that empty
nodes must be formed in the cation part of tile latti.ce. The
intensity of the lines on Debye samples decreases cqually
accordin- to the rules governing the process. It may be
assumed that the empty nodes are formed at the expense of
the bivalent cation (strontium or barium). The presence
of enpty nodes and trivalent cations in the lattice of the
"perovskite" type must lead to a distortion of the oxygen
octahedron surrounding the titanium-ion and consequently to
Card 3/4 a greater liberty of its translocation. Consequently, a re=

ABSTRACT: The novel technological process of condenser -discharge welding
(CW) of permanently joined members of bicycle frames developed by
the NIITavtoprom (Scientific Research Institute of Technology for the
Automobile Industry) substantially reduces the amount of lab'or
required as well as the weight of the bicycles. The employment of the
CW significantly reduces the consumption of ferrous and nonferrous
metals and auxiliary materials and eliminates such operations as
the manufacture of fittings, their attachment, etc. The electrical
circuitry of CW is examined. Technical specifications and photo-
graphs of the CW machine are given. At a current of up to 300,000
amp the productivity of the machine amounts to 100-125 welding
Card 1/2 operations per hour. As a result of in%estigations carried out to

determine optimal conditions for CW, relationships were established between the
strength of the welded joints and the current density, the charge potential, the com-
pression force, the overhang of the pipe, etc. (the data are compiled in the form of
diagrams). Vibration- strength tests yielded favorable results. A prototype of an
industrial CW machine was designed and consitructed. The employment of the CW
technique reduces the labor from 41-44 to 5-15 minutes per frame and lowers the
cost of manufacture per frame from 12-13 to 5-7 rubles.
