TEXT: The rigidity tests of machine tools according to rD(,r(GOST)
7896-56 render it difficult to use the test results for the rating of
machining accuracy. The author suggests a test method, the application of
which makes it possible to combine the test results with the rating of
machining accuracy. In the suggested method the ratio P :P jP - 1-OOgO.50;
tO.25 instead of 1.00:0.58tO.OO of the GOST standard; tRe 5owxer arm is
50 mm instead of 25 mm, the stress is applied to the live center and not
20 mm lower as it is the case with GOST; the tail spindle sweep amounts
to 60 mm, instead of 120 mm. The lathe spindle is loaded by the torque.
The compression of the head and tail stocks are measured separately. The
full Py acts only on the carriage, while only half this force is acting on

the stocks. The test results by the suggested method and by GOST should
differ from each other. It is recommended to use the suggested method for
check tests. If the rigidity test results by the GOST method are used for
the rating of machining accuracy with the tail stock center, it is neces-
sary to multiply the total rigidity near the head stock by 0.8 and the
total rigidity near the tail stock by 1.15. For the rating of machining
accuracy, it is necessary to know the rigidity of the main units, taken
separately. The total rigidity by the GOST method should, after multi-
plication by the correction coefficients, be divided among the units
according to the presumed rigidity ratio of head stock, carriage and tail
stock j@R:,Jca ' .00 : 1.50 1 2.00, which is recommended for the

TITLE: The Rigidity of the Machine Tool - Work-Piece Elastic System at
Turning in the Chuck
PERIODICAL: "Tr. Kuybyshevsk. aviats. In-t", 1959, No. 9, pp. 65-79
TEXT: When turning in the centers, the change In the shape of the processed
work-piece due to deflection is opposite to the change in the rigidity of the
machine tool and the processing errors may be mutually compensated, partially at
or fully. When turning in the chuck, the change of the machine rigidity and th
of the work piece produce the same error in the shape of the work piece and sum up
always, Increasing the inaccuracy of processing. Tests conducted on the lathe
IK62 (lK62) showed that the rigidity of the machine - work-piece elastic system
decreases inversely proportional to the overhang of the work-piece with increasing
overhang of the work-piece out of the chuck jaws, within the overhang limits
100-200 mm(neglecting the deflection of the work-piece proper). The two types

ABSTRACT: The possibilities for the construction of a non-linear o4actron
transformer with one input are investigated. The results of the
elaboration of the basic types of non-linear transformers: com-
bind with diodes, with diodes and triodes, and with compensation
are given. The working method of this device and a description of
th*P-1 apparatus are given. This is the result of a long develop-
ment and it has shown positive results. The securing of greater
exactness, stability and the extension of the class of the re-
produced curves was solved by the introduction of the compensation
principle. In the case of less severe requirements NP-1 should
be used with diodes. However, if curves with great slopes and
strong salient points are to be reproduced, it is more profitable
to use NP-1 with diodes and triodes or combined MP-1. In special
cases where increased stability is demanded at a small number of

ABSTRACT: The described and illustrated circuit with silicon diodes
has been experimentally tested by a class 1 microampereme-
ter "M24" with a 100 mka range and 850 ohm internal resi-
stance. Connection of the silicon diodes in parallel with
the instrument did
not change its readings in a temperature
0
range of up to +70 C, and input voltage exceeding 100 times
the measurement range did not cause breakdown. The micro-
amperemeter was subjected to only a fivefold overload.

;TRACT: Ali Author Certificate has been issued for a phasemeter to measure ultra- 1
i electrical oscillations. The phasemeter consists of input comparator circuits
shape pulses while input signals are passing through zero, a trigger, a linearly
.ying voltage generator, and an output memory circuit. In order to provide
:omatic phase measurement directly in degrees, and to insure the independence of
idings from the value of the direct component of input 5ignals, the linearly
-ying voltage generator is designed as an integrating amplifier whose input is
inected to the outputs of the frequency meter and an inverter, at the frequency
:er output through the series networks which consisted of a diode and an input
;istor. The control key circuits are connected to the diode junctions. IGS)

TITLE- Pecubwities in the grcwth, twinning and structure of
germanium dendrites and abnormal impurity segregation in
the process of dendritic crystallization
PERIODICAL: Fizika tverdogo tela, v. 4, no. 1, 1962, 36 - 43
TEXT: The optimum conditions for growing long dendritic germanium
crystals were studied. The twin structure of real dendrites was deter-
mined and complete agreement was found between the twin structure of seeds
and of crystals grown from them. Impurity segregation coefficients and
the distribution of impurities were measured. The dendrites were grown by
the Czochralski method (rate of linear growth 10 - 15 cm/min) and were
150 - 300 thick, 1.5 - 3 mm wide and 400 mm long. They were produced
with varyi'png impurity concentrations, surface perfection and thickness.
They could be divided into 4 groups according to twinning propertiest
(1) Homogeneous twin structure right across; (2) homogeneous twin struc-
ture, but only in the middle of the dendritei (3) cross-sectional twin

structure but becoming simplified toward the edges; (4) cross-sectional
twin structure which becomes more complex toward the edges; up to 32 twins
were observed at the edges. Billig's proposition (Acta Metall., 2, No. 1,
1957) that twinningmaybe caused by impurities was not confirmed;
impurity concentrations of up to 1020CM-5 caused no additional twinning
effects. However, a higher impurity has an unfavorable influence on the
quality of the dendrites. The segregation coefficients were measured for
In, Ga, Sb, and B in dependence on their concentration in liquid phase.
In each case 5 - 7 measurements were made in the following ranges of con-
centrations: In:2-1014 4-10 19CM-3, Ga:1-1014 _ 6-101 8CM-3, Sb:6-1013
- 2-10 20 cm-3, B:1-1014 4-10 19CM-3. In, Ga, and Sb show anomalously high
14 -3
segregation coefficients (Keff >1) at concentrations of 10 Cm , which
fall smoothly with increasing concentration. At 10 18 - 10 20 Keff of Ga
coincides with the equilibrium values. K of B reaches 0.5 at 1014

A.3ST-I?iCT The purpose of the present viork was the production of plastic-
-scintillators of a large circumference with gooa transjarence
for fluorescent radiation, and a maxi;:,u:a ratio 3E/T yield of
energy the duration of scintillation). The impulse-a;aplitude in
a plastic-scintillator is not only dependent on tht-lactivator-
concentration, but also on the pArity of the sol-ent and that of
the activator. The influence exerted by benzoylperoxide u,)on the
impulse-amplitude was investigated here and data for some samp-
les which were produced with catalysts and without catalysts arc,
,-iven. It is shown that the plastic-scintillatGrs which were pro-

transparent enough. Some substances of the oxazole-class
also investigated. These were used in plastic-scintillators as
well as base-fillers as as additions to p-terphenyl and 2,5-di-
ph(znyloxazole. It is shown that in these substances the maxi-
mum amolitudes are attained at an activator-concentration of
0,5 -@ 1,o ',@. The best results were attained in saL;--)les with PBD
as a@tivator. The sample with 1 % PBD in polystyrene without
benz(Zzlperoxide shows impulses whose amplitude amounts to o,q
with reference to stilbene. The 3UMPlC with 1% uNPO (i.e. 2-
(1-napht@yl)-5-phenyloxazole) in polystyrene without benzoy.1-
peroxide yields impulses whose amplitudes amount to 0,73 with
reference to stilbene.- PBD is 2-phen,,,1-5-(4-biphenyl)-1,3,4-
oxydiazole. POPOP is 1,4-di[2-(5-phenyloxazolyl)j benzene. It
is finally shown that the plastic-scintillators which are pro-
duced with p-terphenyl and luminescing additLons of POPOP,BBO and
aNPO and which possess a comparatively good transparence for
charactc@riAtic radiation, can be successfully used for scintill-

ABSTRACT: In a previous investigation (FTT, 1966, 8, 2117) the authors developed an appro-
t'j
ximate theory of the temperature behavior of an impurity atom in a ferromagnetic crys @'l
in the presence of a positive exchange coupling with its envirom-nent. In these conditions i@e
impurity spin is always oriented along the spontaneous moment of the crystal, but given certain.
relationships between the parameters characterizing the matrix and the impurity, the tempe-
rature-induced change in the magnetization of the iinpurity atom may markedly differ from
the change in the magnetization of the atoms of the matrix. Now the authors calculate with the

id of Green's temperature functions the magnetization ofthe impurity atom in a ferromagnetic
@rystal over a broad range of temperatures in the presence of a negative exchange coupling
etween this atom and the matrix. Owing to zero oscillations in the spin system with an antifer-
-omagnetic orientation of the impurity spin, contractions of the z-projections of the spins of
he impurity and matrix atoms occur in the ferromagnetic crystal, thus leading to inhomogenei-
y of magnetization of the crystal in the fundamental s@ate. It is shown that in the case of a feeb
y coupled impurity its magnetization may sharply diminish at a temperature at which the mag-
Letization ef the atoms in the matrix is still close to saturation. As a result, given a suffi-
dent concentration of the impurity, the spontaneous moment of the crystal will increase with
emperature in the low-temperature range. 'The authors are indebted to Ye. A. Turov and

ABSTRACT: This is a continuation of earlier work (ZhETF v. 49, 1887, 1965), where a
spin-wave theory was developed for a Heisenberg ferromagnet containing a magnetic
impurity atom. In the present paper it is shown, using two-temperature Green's func-
tions, that under certain conditions, when the exchange coupling between the impurity
and the matrix is much we4ker than the exchange coupling of the matrix atoms, the
spontaneous magnetization@@of the impurity atom in the ferromagnetic crystal has a
specific temperature dependence./ It can become very small at temperatures at which
the magnetization of the matrix atoms is still close to saturation. Such a behavior
of the impurity spin is due to the existence in the elementary-excitation spectrum of
a narrow resonance level lying at the bottom of the band of the quasicontinuous exci-

ation spectrum. This level corresponds to resonant states of the spin excitations
Ith maximum at the impurity atom, so that these states begin to fill up rapidly at
emperatures at which the average thermal energy is of the order of the resonance-
eve! energy, thus ensuring a sharp decrease of magnetization of the impurity lattice
oint. The distribution of the magnetization around the impurity lattice point is
alculated. Orig. art. has: 33 formulas

erence that it deals with the theory of the inelastic scattering of neutrons in a ferromagne-

a the spin projection of the antiferromagnetic aligned spin does not equal in absolute fi-

Dr of the nonuniform distribution of the magnetic moment in the neighborhood of the defect.
-xperimental determination of the inelastic neutron scattering cross secti, ns in such a
;tal would make it possible to investigate the structure of spin excitations in the crystal.
e, however, this question is investigated theoretically alone.) The case o@ negative ex-
ige coupling between the impurity and the matrix is considered, with the impurity spin in
fundamental state being oriented in a direction antiparallel to the direction of the magnetic
-r of the matrix. Compared with the case of ferromagnetic impurity, neL.. -,on scattering
uch a crystal displays a specific feature; the noncoherent part of the cross section has a
rp peak even at transition energies lying within the quasicontinuous spectz 1M region. be-
3e states of a special kind, whose excitation enhances the spontaneous moment of the
,tal, participate in the scattering. Recording this peak makes it possible to determine the
iange integral impurity-matrix. Orig. art. has: 38 formulas.

USTRACT: A method is developed for determining the7*state density in thf- Magnon spec@
trum of a ferromagnetic crystal from data pertaining to inelastic scattering of neu-
trons. The method is based essentially on reducing the problem to the c;!Iculat: , I
Df the Green's function of the crystal containing one non-magnetic impurity. IT is I
shown thereby that measurement of the scattered neutron energy distribut-*Gn should t
not be carried out for a perfect ferromagnetic crystal, but for a crystal containing
9. small concentration of nonmagnetic substitution atoms. In this case the cross
section defined by the incoherent single-magnon scattering impurities can be expressed
in terms of the density state in the magnon spectrum of a perfect crystal. Although 1
the concrete calculations are presented for a simple cubic lattice, they can be readi-,
