ABSTRACT: A phenomenological theory of combined ferroelecLric and ferromagnetic
p:ienomena is constructed in analogy with the Weiss theory of ferromagnetism. The mo-
lecular magnetic field is assumed to be the sum of the magnetic field and a term
proportional to the magnetization, as in Weiss' theory, and an additional interac-
tion term proportional to the electric polarization-. Similarly, the molecular elec-
tric field is the sum of the electric field, the Lorentz term proportional to the
polarization, and an interaction term proportional to the magnetization. The coeffi-
cient of the magnetization in the expression for the molecular electric field is
Card 1/3

ACCESSION N`R: AP4030633
equal to that of the polarization in the expression for the molecular magnetic field.
This addition to polar and axial vectors is Justified by a footnote to the effect
that it should be valid at least for those crystallographic classes that do not ad-
mit of reflection or time reversal as symmetry operations. By calculations that are
presumably identical to-those of Langevin and Weiss, expressions were derived for
the transition temperatures, the three susceptibilities (magnetic, electric and
mixed), and the spantaneous polarization and magnetization. These expressions reduce
to those of Weirts' theory when electrical effects are absent, and to those obtained
by W.Mason in his theory of Rochelle salt (Phys. Rev. 72,854,11347) when magnetic ef-
fects are absent. Various interaction effects occur. For example, if the electric
transition temperature is greater than the magnetic transition temperature, a weak
spontaneous magnetization appears at Intermediate temperatures. A Hamiltonian is
writter, for a double lattice having magnetic dipoles at half the sites and capable
of electric polarization at the remaining sites. This Hamiltonian contains Ising's
term for the interaction energry of tne magnetic dipoles, an analogous term for that
of the electric dipoles, a term for the interaction energy of the electric with the
magnetic dipoles, and an elastic energy tam that limits the electric polarizabili-
ty. An approximate nartition funation was derived from this Hamiltonian by Basolyu-

ABSTRACT: For a number of years the authors have been engaged in calculatfng the
internal electric fields in compounds having the perovskite structure and peculiar
dielectric properties. The methods of calculation and the results have been reported
in a series of papers appearing in Kristallografty (Cryst6llography) and Fizika
tverdogo tela (Solid State Physics) from 1958 to 1962. The results of these calcula-
tions are discussed in the present paper. The calculations were based on the ionic
model of a crystal with known or assumed structure. The charges and polarizabilitles
of the point ions were treated as given quantitiao, but the induced dipole moments

rizability, and radius of the ions; reasonable variations of these paramcters 6 1

Good agreement was obtained between observed and calculated values of the @;pont.1;1-
eous polarization with the value 0.5 for the ionic charge factor. The results of
the calculations indicate that NaTa03 and CdT103 are ferrielectric materials and
that PbZr03 is a ferrielectric material with nearly antiferroelcctric properties.
The internal field at the position of the Ti ion was found to vanish in CaTiO3 but
to be large in BaT'03 and PbT103. This difference in the fields accounts for the
different dielectric behavior of these materials. Because of the strong field at the
Ti ion, the conclusion of II.D.Megaw (Acta crystallogr.,5,739,1952; lbid.,7,187,1954)

ABSTRACT: The Sverdlovsk Mining Institute conducted extensive tests
with different shot. boring bits to establi-5h the main factors
which increase the resistance to wear of the bits under
different geological conditions These factors are; 1) the
influence of the hardness of shot boring bits on the drilling
speed, 2) the influence of the chemical composition of these
bits on their resistance to wear and on the drilling speed;
and 3') the influence of the shape of the bits on their re-
sistance to wear and on -@he drilling speed (See Graphics I

ABSTRACT: The high losses caused by the polarizer can be avoided by using instead
A glass plate whose'angle to the axis of the instrument can be varied. The glass
plate, which is placed between the neodymium glass rod and the output -window,
affects the efficiency of the resonator by determining the polarization plane of
light oscillations. During experiments, the emerging beam vas split by a half-
transparent mirror, and the intensity of the two components was compardid on a two-
channel oscillograph. The measurements showed that if the glass plate is inclined
at a small angle to the axis of the resonator, an almost complete polarization of
the stimulated radiation can be obtained without involviAg great losses of energy,

TITLE: Two-channel single-pulse lasef with an energy of 180 joules
SOURCE: Optiko mekhanicheskaya promyshlennost', no. 6, 1966, 46
TOPIC TAGS: solid state laser, laser emission, neodymium glass
ABSTRACT: An investigation was made of a laser in whiih high emission energy of the
light pulse was obtained by the use of neadymium glasdl@rods. Cylindrical specimens
of glass (45 mm in diameter and 250 mm long) activated.with neadymium were connected
in series-parallel. Each specimen was optically pumped by six direct pulse lamps
placed in a multielliptical illuminator. The laser consisted of two identical
channels, each containing three rods assembled on one axis. Q-modulation was done
by two prisms fixed on a common shaft rotating at 18,000 rpm. rhe light diameter
of the prism (30 mm) was coordinated with the light diameter of the operating rod by
means of a Galileian tube. The experiments showe4 that for effective pumping of an
operating body 45 mm in diameter the content of Nd203 should not exceed 4%. In this
way it is possible to obtain an amplification coefficient of one rod equal to 3 and
provide a yield energy of 25-30 joules from one specimen. Connecting the rods

in series reduces the amplification of optical pumping, owing to the appeararce of
free generation of the whole channel. This difficulty can be eliminated by introduc-
ing, between the rods, optical decoupling filters made of uranyl glass. The filters,
together with the operating rods, are placed in the laser illuminators and are
pumped simultaneously with the rod. The optical density of the filter is selected in
such a way that at maximum pumping no free generation appears in the laser channel;
when the filters are illuminated at the moment when maximum Q for the resonator is
reached, one light pulse is generated. By introducing optical decoupling, emission
with an energy of 90 joules at 10-7 sec duration was obtained from one channel of the
laser. The angular distribution of generated radiation improves as the optical
pumping increases. Synchronous inclusion of two laser channels was obtained by
appropriate adjustment of the laser elements. The time spread of the pulses emitted
by both channels did not exceadjo-8 sec. With the aimultapeous inclusion of two
channels, a light pulse with an energy of 180 joules (corresponding to an emission
intensity of 1.5 to 2 hw) was generated. (JAI

laser cavity mirrors on the angular distribution,
22, no. 1, 1967, 123-126
TOPIC TAGS: solid state laser, neodymium glass laser, electrooptic effect, image
converter, laser cavity, beam divergence
ABSTRACT: The authors measured the laser beam divergence angle and the deviation of
the beam from a perpendicular direction to the plane of the mirror, as Nnctions of
the misalignment of the mirrors for different resonator lengths (500 - 2800 m,) and
different resonator diameters (2.6 - 15 mm). A neodyTnium-glass laser was used. The
laser emission was photographed through an electrooptical converter whose cathode wasi
placed in the focal plane of the lens. In the case of small misalignment (not ex-
ceeding mo = a2f/d3, where I is the length and d the diameter of the cavity and X is
the wavelength), the broadening of the angular distribution -waries linearly from X/d
at zero misalignment to a/d at a misalignment angle a.0; this is in good agreement
with theoretical results by one of the authors (Lyubimov, Opt. i spektr. v. 21, 224,
1966). In the case of larger misalignment angles the radiation becomes distributed
aver individual discrete directions, the angle distance between which is equal to

double the misalignment angle. A plot of the angular distribution against the rela-
tive misalignment shows that the former increases like the cube root of the relative
misalignment angle. The deviation of the b.2am from the direction normal to the sur-
face of the mirror is approximately equal to (dcL/1)112. All the results agree well
with the earlier theoretical studies and with earlier experiments by the authors
(Opt. I spektr. v. l9j 286, 1965)- measurements of the beam deviation make it pos-
sible to estimate the losses in the resonator, and these resuits agree with calcula-
tions by L. A. Vaynshteyn (ZhETF v. 44, lo5o, 1963). Orig. art. has: 4 figures.

ABSTRACT: A comparison of the papers CRef 1-7 and Z_Ref 2-7 sho,is that
the conceptions concerning the adsorption of water molicules
on microporous glass or silica gel are very different. In
order to clear this question the authorki consider the ab-
sorption spectra of water adsorbed on the surface of micro-
porous glass, where simultaneously the adsorption isotherm is
measured. These experiments lead among others to the follow-
ing results t Before the adsorption of water vapor a soak?d

ABSTRACT- The authors studied changes in the intensity of the band
representing the first harmonic of the OH-groups of the
microporous glass surface with methanol and phenol
adsorbed from low-concentration solutions in CC1 4* A
double-beam infrared spectrometer IKS-2 with a glass
prism F-1 was used. Microporous glass aamples of 8.5 mm
thickness were prepared using a technique described by
Yaroslavskiy (Ref 1); their specific surface area was
275 m 2/g. Before each series of experiments the samples
were etched in nitric-acid vapours for ten hours, carefuji
washed in distilled water and heated for twelve hours in
vacuum at 300 0C. Then the samples were placed for
Cardl/4 12-15 hours in cells with appropriate solutions. The

following bands were observed in the infrared spectrum
of a sample immersed for 12-15 hours in pure CC14: a
narrow strong band at 7 250 cm- 1 (first harmonic of valence
vibrations of the surface OH-groups), a weak band at
5 290 cm-I (harmonic of a composite valence-deformational
vibration j OH + 6OH of adsorbed water) and a band of
medium intensity at 4 470 cm-1 which probably consisted of
a second harmonic of deformational -vibrations of the
surface OH-groups and one of the harmonies of atomic
vibrations in SIO4 tetrahedra. In the absorption spectra
of glass samples immersed in solutions of methanol and
phenol in CCI4 the following regularities were observed
in the behaviour of the 7 250, 5 290 and 4 470 cm- I bands:
1) with increase of the solution concentration the
intensities of the three bands varied periodically passin.-

2) in the case of methanol the maxima and minima of the
three bands coincide, i.e. they occur at the same
concentrations but in the case of phenol this coincidenie
is observed only in the case of the 7 250 and 4 470 cm-
bands; 3) the periodic minima and maxima of the band
intensities are clear until the adsorbed films on glass
reach a thickness of one mono-layer; with further increase
of the solution concentration the minima gradually
disappear. Similar periodic maxima and ninima were found
in the infrared absorption spectra of wicroporous glass
when methanol was adsorbed on it from irapour phase
(intensities of the bands were plotted against vapour
pressure). The observed behaviour of the infrared band
intensities and the anomalies in the isotherms of
adsorption and heats of adsorption from solutions, reporte6

Title System of automatic magnetic scanning of mass-spectra
Periodical Zhur. tekh. fiz., 25, No 13 (Novirebery, 1955, 2282-2285
Abstract One of the principal units of the mass-spectrometer intended for molecular
anaylsis is the system of spectrum scanning. The best method for scanning
is the variation of the magnetic field strength of the mass-separator.
For the satisfaction of most practical problems the scanning must encom-
pass the range of masses from, 12 to 200. In certain cases there arises
the necessity of expanding this range toward one or the other side. The
principal difficulties of the realization of magnetic scanning are not
the overlapping of the indicated range of masses (V. L. Tal'roze, ZhTF,
same issue, p. 2280-2281), but, on the one hand, the exclusion of spon-
taneous fluctuations in the magnetic field strength in the scanning
process and, on the other hand, the automatization of the scanning pro-
cess which would jointly with the recording system ensure the minimum tire
expended upon the recording of the spectrum. The latter consideration
makes desirable the variation of the mAgnetic field strength in accordance
with the exponential law according to time (see V. L. Tal'roze, op. cit.).
The problem of magnetic scanning of mass-spectra was solved by the authors

Card 2/4 FD-3150
in connection with the development of an analy-,ic mass -spectrQmeter MS-1
(Tekhnicheskaya dokumentatsiya promshlennogo obraztsa mass-spektrometer
MS-1 [Technical documentation of industrial sample of the rrass-spec-
trometer MS-1,1, in which for overlapping of T-ass range 12-200 with
accelerating potential of luOO volts there is required (taking into
account hysteresis) a change in the current of the mass-separator's
electromagnet from 20 to 140 microamperes. Elimination of magnetic
field fluctuations inadmissible during taking of mass-spectra is effected
by strict stabilization of the current in the windings of the electro-
magnet at each ialue of this current established during the scanning
process. As noted by the authors, the literature has published only one
system of automatic magnetic scanning of wide mass-spectra (J. A. Hipple,
D. J. Grove, W. M. Hickam, "ev. Sci. Instr., 16, 69, 8, i945; D. Grove,
J. Hipple, Rev. Sci. Instr.,18, 537, 1947). In this system (see figure
of Hipple scanning circuit) stabilization of current in the windings
of magnet is realized indirectly: one stabilizes the voltage of the
source supplying the circuit controlling the magnet current and main-
tains practically invariable the consumption of current from this source
etc. The scanning system developed by the authors is a system of'
current stabilization directly in the windings of the scanning electro-
magnet; each value of the current strength in the electromagnet is
assigned by the supporting potential of the stabilization system, this
potential being able to vary, together .&th the current in the electromagnet

Card 3/4 FD-3150
windings, according to any law in time, including the exponential law.
The current stabilization system is an ordinary system of static regu-
lation: the current in the electromagnet windings IM flows through
constart control resistance Re the voltage drop Ulu-TmRe n which is
compared with the support potential Uo; an electronic circuit -if great
sensitivity tries to maintain the equality of these voltages, thanks to
which practically full proportionality between current Im and support
voltage Uo is attained: Im ^JUo/Re. Departure from exact proportionality
is determined by the circuit parameters, considered by the authors in
the remainder of their work. The principles governing the scanning circuit
realized by the authors are shown in figure 2 (Theoretical circuit of
smooth scanning in a wide range): The electromagnet winding is connected
to the anode link of the output tube of the electronic circuit (this tube
is characterized by large transconductance S), and control resistance
Re is connected to cathode line,- the voltage difference ImRe-Uo is
amplified by a voltage amplifier k times and is fed into the controlling
network of the output tube, here the exact relation between support
voltage and current having the following form: I,,=kSU,/(kSR,+2), which
passes over into the above-mentioned expression TLmVJo/Re for large values
of effective transconductance of the electronic circuit kS. On a similar
principle the authors constructed the system for the stabilization of
current in the magnet of the mass-spectrometer MS-1; in this system,
however, the magnet's windings, just as the control resistance, are
connected to the cathode link of the output tube, In consequence of which

Card 4/4 FD-3150
the dynamic range sf ncirmaL amplif iers of vDltage turr.3 _)ut t(; be
insufficient for overlapping Df the entire scannLng range into one
receiver; therefore along with a smooth reg-ulation of magnet current
use is made of step change-iver of regulation Anits e.g. in the system
NIS-1, in which exists current variation from ') to 50C microamperer@,
there are 17 such steps". The nece9sity of carryin6 jut step chant,e-
over complicates the auturaitization of the scanning process. The
authors' scanning system was realized in two varLants: with linear and
exponential variation cf the magnetic field strength in time, the di'L-
ference between these variants consisting only in the methods of ob-
taining the support voltage: in the case of the iinear scanning the
support voltage 1-s taken from the rheochord set in motion by a reversing
electric motor, and in the case _@f exponential scanning the support
voltage is obtained in link of a condenser discharging into fixed R.

TEXT- The process temperature is one of the most impo7tdni
parameters during the polymerization of dienes in general, and
during the emulsion polymerization of @hloroprene in parti_-;1_La_-
it affects many of the properties of the synthetic poly,_-hlD-Opr@_ne
rubber Nairit when produced on an industrial scale by emulsi,@n
polymerization. The process temperature affects, for example,
the rate and the degree of crystallization, the tensile str;_Lngtk-
plasticity, solubility, and physical and mechanical properties @)f
the vulcanizates. This is mainly due to variations in -he
microstructure of the polychloroprene macromolecules and is
closely connected with the distribution of the monomer in the
polymer-chains and the character of the bonds between the @hains

Ref.9i ZhOKhl7, 941 (1947)) carried out investigations on @he
association of the monomer-links during the mass polymerization of
chloroprene but the present authors were unable '@o tra-e any
literature data on the micro-structure of Nairit@ these data are
of great practical interest, especially in connection with 1DW-
temperature rubbers. The structure of Nairit was determined by the
ozonization method (first described by Harries in 1929) in order to
define the relation between the polymerization temperature and the
linear structure of the chains and the effect of the disruptian of
the regularity of addition of the monomer-links on the properties
of Nairit. The method is based on the addition of ozone to the
unsaturated bonds between the C-atoms the formation of an
ozonide which is subsequently decomposed and the analysis Of the
decomposition products. Experiments showed that an increaa=_ in
the polymerization temperature caused a disruption of the
regularity of the structure of 1,4-polychloroprene whi--h leads to
the formation of considerable quantities of 1,2- and possibly

technological properties of the Nairit rubbers- The number G'L
chains in the 1,2- and 3,4-Position was found to inzrease fr..),m 1,94
to 8,30% when the polymerization temperature was raised fr,3m 10

temperature of -20*Ci 10 g of Nairit was subjected to this pr3c@-ss

structure of the chain has an adverse effect on the proper-ies -,f

TEXT: The paper reports the results of the investigation of
the composition of chloroprelie-chloroisoprene copolymers in
relation to the concentration of chloroisoprene in the starting
mixture of monomers and depth of conversion of the monomers.
The polymers were subjected to ozonolysis with the subsequent
determinations in the ozonolysis products of levulinic acid,
equivalent to the content of chloroisoprene in the polymer chain.
The quantity of succinic and formic acids permitted evaluation of
the number of chloroprene sections. It was shown that for
introduction into the monomer mixture of 5% of chloroisoprene:, the
latter almost completely enters into the composition of the

copolymer. When the concentration of chloroisoprene in the
mixture increases from 5% to 605, the coefficient of its utiliza-
tion in the polymer decreases from 9C6 to 52@6- For the mixture
containing 10% of chloroisoprene polymerized to different depths
(50@o to 90',@6), the coefficient of chloroisoprene utilization
remained constant at Wo' for all the samples, which indicated the
independence of the ratio of monomer units in 'the polymer from
the depth of polymerization. Combination of monomer sections in
positions 1,2 and 3,4 in the copolymer is approximately the same
as in chloroprene polymer and constitutes on average 10-Yo of all
sections in the copolymer chain.
There are 2 figures and 2 tables.
