ABSTRACTs At the destruction of spiinter-proof automobile windvttelds
and windows the glass breaks into minute splinters and,ioses
its transparency. It was therefore necessary to produce wind-
shields which retain their transparency at least in a certain
small sector. In 1957 the first samples of such windshields
were produced in the USSR at the plant imeni Dzerzhinakly
(see footnote 1). The authors of the present paper succeeded I
obtaining such panes, called stekloron, with differont degreeE
of hardness (Fig 1). The center part of the panes is Rhielded
off, as isshown in figure 2, by the applica%ion of protective
coatings of kaolin and aluminum dye. They are then heated in
an electric stove to a temperature of WO and then cooled on
a grid by an air jet. After annealing the )rotective coating
removed. It was found by testing steklofon according to the
GOST 5727-57 method that such panes are not damaged by an 80C

also tolerates temperature drops within a range of 1250. At a
temperature drop of 135 0 steklofon breaks along the ring
.separating the two parts of differeht degrees of bardness, as
can be seen from figure 3. There are 3 figures and 1 Soviet
reference.

TITLE: Production of Roat-resistan Sheet-glaspby Means of the Method
of Continuous Rolling
PERIODICAL: St*klo I keramika, 1960, Nr 4, PF 4-12 (USSR)
TEXT: In the article under review the authors describe the methods used to
produce heat-resistant sheet-glass by means of continuous rolling, which were
developed by them in cooperation with I. G. Gurviis.-Yo. G. Gurvits, 0. V.
Vyshinekaya D. F. Milodanov. G. I. PcTtoratakiy V. A. Zhelezteov, &_A. Korsun,
and Ye. S. Gnedashevokays. The first experiment was performed with XKR-1 glm'20 %be
furnace shown In figure 1. An ordinary rolling machine with two rolls made of
EKh-25 steel (diameter of 320 am, water cooling) was used for this purpose. The
glass band was annealed in a furnace of the type LV-1OOOx18 of the iaivod"~Steklo-
mashina" (Plant "Steklomashina"). The temperatures of the glass-melting furnace
are shown in figure 2. The quality of KKR-1 glass is listed in table 1. The
heat-resistant glass produced in this way was unsuited. Nonalkaline glass of the
sort Nr 31, which meets all requirements~ was obtained by experiments. Its
composition and some of its physicochenical properties are given. A now tank
furnace was installedp whose design and temperatures are shown in figures 3-6

and 7 1 re!pectively. The EKh-25 rolling machine which has rolls 120 ~ in
diameter instead of 320 on), is illustrated in figures 8 and 9. Data on the
glass band and the rolling rate are contained in table 29 and the quality of
polished glass in shown in table 3. Figures 10 and 11 illustrate the condition
of the furnace lining after a campaign of nine months. Mass production of heat-
reoistant glass is only possible by means of a tank furnace designed for high
melting tesperatures and an output of at least 300-350 kg/24 h per 1 K2 of the
hearth. It is further necessary to build a rolling machine whose rolls are
made of heat-resistant steel and warrant normal operation in the temperature
rang* 1400-14200. It is also necessary to establish a continuously working
annealing furnace which permits normal annealing of the glass band. There are
11 figures, 3 tables, and I reference.

Submicroscopically Inhomogeneous Structure S/072/60/000/012/006/008
of Glass B021/BO58
V. P. Stativ and V. N. Karlyuk assisted in the structural analysis. The
electron micrograph of the surface of B2 03*3SiO. glass is shown in Fig,2.
The results of the authors agree with the conceptions of Ye. A. Poray-
Koshits and S. P. Zhdanov on the structure of borosilicate glass. Sodium
borosilicate glass (6% Na 0, 29% B 0 , 65% Si~) shows inhomogeneous
2 ~nt 3
zones but remains perfectiy transpar (Fig. , thus proving
0. K. Botvinkin's hypothesis on the structure of glass. The heat treat-
ment of these glasses at temperatures between 490 and 8000C changes
their structure radically (Fig-4). Large and small pores can be detected
by irradiating a preparation of porous glass, which was obtained by com-
pletely leaching out sodium borosilicate glass in hydrochloric acid
(Fig-5). Tests of some industrial glasses, the composition of which is
tabulated, showed that phase composition is characteristic of most
types of glass. Inhomogeneous regions were detected in samples of Pyrex
glass with slight opalescence (Fig.6). The mass-produced glass No. 31
has a oubmicroscopically inhomogeneous structure, which is distinctly
marked after heat treatment (Fig-7). After hardening, zirconium glass
~-18 (Ts-18) shows inhomogeneous regions (Fig.8). Inclusions similar to
Card 2/3

86455
Submicroscopically Inhomogeneous Structure S/072/60/000/012/006/006
of Glass B021/BO58
crystal formations were discovered in samples of mass-produced window
glass which had been subjected to heat treatment and remained transparent
(Fig.9). A liquation in the absence of a crystalline phase was discovered
in continuously rolled glaso after heat treatment (Fig.10). The mass-
produced transparent glass 0253 has a submicroscopically inhomogeneous
structure (Fig.11). Lithium-containing glass remained transparent after
heat treatment and exhibited a submicroscopically inhomogeneous struc-
ture in the absence of a crystalline phase (Fig.12). Transparent glass of
the cordierite system showed no chemical inhomogeneity but a crystalline
phase (Fig-13). The properties of glass and microcrystalline materials VY
can be influenced by regulating the process of liquation, i.e., the sepa-
ration of glass into phases. The authors' studies of the aubmicroscopical-
ly inhomogeneous glass 3tructure contradict Zachariasen-Warrenis hypo-
thesis on the structure of glass as a continuousq disordered lattice,
and prove the crystallite hypothesis by A. A. Lebedev and the aggregation
hypothesis by 0. K. Botvinkin. There are 13 figures, 1 table, and
13 references: 6 Soviet, 4 German, and 3 US.

TEXT: The authors describe a simple dilatometer with rapid
response suitable for studies of phase transformations at high
rates of heating. The detector is a capacitor with a movable
(b) and fixed (a and c) electrodes (Fig. 1). The change of
length of a sample is transformed into a change of capacitance
by motion of the movable electrode. The two electrode systems
(ab, cb) form parts of two separate oscillatory circuits working
at or near resonance. The resonance is distributed when the

capacitances ab and bc are altered. This affects the natural
frequencies of the circuits and the anode currents of a double
triode (oHj5n (6N15P). An induction coil L2 and capacitances
C1 and 02 form the grid circuit, while inductance Li and the
the capacitance Ceb form the anode circuit of the left-hand
part of the double triode. Both these circuits are loosely
coupled, and the coils Li and L2 are placed on the same axis.
The grid circuit is tuned by means of C2 so that any change of
C,b produces a directly proportional Increase of the anode cur--
rent. The oscillator on the right-hand side contains Cab and
is constructed in a similar fashion, The circuits are assembled
from intermediate frequency filters of the audio parts of the
"Rekord" television set. When the capacitances Cab and C,b
are varied, the current in one triode increases and falls in the

other. The difference current is passed through loop no 8 of
an oscillograph m no-a (MPO-2) connected between the triode
anodes. The direct proportionality between the oscillator indica-
tion and the dilatometer displacement is obtained by suitable se-
lection of the ga~ betw(,en the fixed electrodes a and c and
of the working regions ca the resonance curves of the oscillators.
The instrument constructed by the authors has a linear charac-
teristic for capacitor plate displacements of 0 - 1 mm. The in-
strument gives reliable dilatometric curves when used in conjunc-
tion with a loop oscillographe The oecillograph readings are
practically unaffected by the cathode drift and supply voltage
variations. There are 2 figures and 2 Soviet-bloc references,

examined the existence of a reverse martensitio transformation. Iodides
of both metals were used for the production of the alloys. The
production method is described in detail. The apparatus used for the

only a martensitic alpha prime phase; an undercooled beta phase could not
be fouod. The authors arrive at the conclusion that the residual beta
phase in the Ti-Zr alloy is the smaller the lower the amount of nitrogen
and oxygen impurities in the alloy. The alpha prime phase has the
characteristic martensitic structure, and0the reverse martensitic trans-
formation could be proved on heating (500 C/sec). Fig. 2 graphically
shows the transformation temperatures for direct and reverse martensitic
transformations as a function of the composition of the alloy. In the
range from 40 to 80 at%, the transformation temperature is independent
of the composition. The authors conclude from the results that in the
ranges from 0 to 40% Zr and from 80 to 100% Zr the transformation/3-o-a'
takes place on quenching in water or in an argon jet. With accelerated
heating the transformation V-PA occurs. In the range from 40 to 80% Zr,
the same transformations occur on quenching in water and on rapid
heating. On cooling in the argon jet (200 - 3000C/sec), however, P-w
transformation occurs besides the transformation mefitioned. Great
significance is ascribed to the formation of them-phase in the Ti-Zr
system, and it is discussed in detail. The results of other authors are
described, and it in found that the difficulty in producing the &*-phase

of the sample is raised. The resistance stability of the thermocouples
is maintained by a slide wireg and controlled by the MD-6 bridge. The
maximum error in temperature measurement is t80C when an mno-2 (MPO-2)
oscilloscope is used. The dilatometric curve is obtained by means of a
differential capacitance pickup which is connected to the anode lines
of two generators with 6H15r1 (6N15P) tubes. Through the capacitance
variation of the pickup, the natural frequency of the generators changes
and, thus, the anode currents of the triodes. A loop oscilloscope is
connected between the anodes of the triodes, and records the difference
of the anode currents of the generators. The potential drop in the
sample during heating is recorded by a loop oscilloscope which is shielded
by an electronic block. The voltage is fed to a rectifier (Ar4-27
(DOTs-27)tube). For various rates of heating, the maximum heating
temperature is adjusted by a time-limit relay which contains a
Tr 1-01/1.3 (TG1-01/1-3) thyratron.and an STV 280/60 stabilizer-divider.
If the sample is to be hardened immediately after heating, the hardening
mechanism is automatically switched on, and argon blown onto the sample

ABSTRACT: A method Jnd equipment for olservation f austenite transformation in a
weld-adjacent zone of medium-alloy steels has been developed at the Institute of
Electric Welding im. Ye. 0. Paton. The method employs a high-temperature vacuum
unit of the IMASH type and permits a direct observation of the microstructural
changes with simultaneous measurements of electric resistance. The construction of
the unit permits loading of the specimens during the thermal cycle and creating
stresses identical to those occuring in actual welds. Deformations are measured
with an accuracy of t1 P. The electric resistance of the specimen during the
thermal cycle is determined by measuring the electric current passing through the
specimen and the voltage drop in the zone of constant temperature field. This metho
of measuring the electric resistance makes possible the investigation of electric
characteristics not only during the heating or cooling processes with or without
deformation, but also under isothermal conditions. Microphotographs of the process

help to determine not only the beginning of transformation, bu't also the type of
transformation (martenslt.ic or bainitic). The final stage of austenitic transforma-
tion is very difficult to register but it can be studied from.the changes in electri
resistance. Orig. art. has: 3 figures.

Abstract Investigates experimentally the relation between (a) the frequency
of synchronized self-excited oscillation and (b) the variations
in its spectral composition that arise when the self-excited
oscillatory system is acted upon by an external periodic force
whose frequency is close to the frequency of one of the harmonics
of self-excited oscillations. Notes that the mechanisms of
synchronization on harmonics of self-excited oscillations, a
phenompnon essentially nonlinear, has been insufficiently studied
amil that, as far as is known, the literature contains nothing
on the variation in the spectral composition of synchronized
oscillations and its relation to frequency. Utilizes K. F.
Teodorchik's energy method (Avtokolebatellnyye sistemy, GTTI,, 1952)

TITLE The Synchroniz!MM fe'Generator for Sinus Oscillations
by a Fractured Multiple Quasi-Elastic Force.
PERIODICAL Radiotecbnikat 11, fare. 7, 50-56 (1956)
Issued: 8 / 1957 reviewed: 10 / 1956
The frequency CO - p/n (n. - 2,3 .... k) of the harmonic exterior force is near the
frequency of one of the sub-harmonies of the eigenoscillations of the generator,
but the eigenfrequency of the generator is co p. The present investigation con-
siders the soft and the hard mode of operatioR of the generator. If the system
produces quasisinusoidal eigenoscillations in the case of a lacking exterior emf,
periodic synohronous-like modes of operation of the generator are possible if an
exterior emf (with p , (0 0) exists. On this occasion oscillations enforced in the
generator are produced with a frequency of the exterior force, and its own eigen
oscillations are synchronized; i.e. its frequency then amounts to w - p. The
amplitudes of the synchronized eigenoscillations depend in a very complicated
manner on the amplitude of the exterior force, but each term of the corresponding
formulae can be interpreted physically. The character of the modification of the
amplitude and the phase in the case of synchronous-like operation depends essen-
tially on the coefficients to be found in the equations with cos T, sin y,
cos 2 T and sin 2 T. In the general case investigation is carried out graphically.
It was proved in theory that phase- and amplitude-jumps are possible. These
jumps may occur according to the direction of the modification of the "detuning"

at various points of the synchronization domain. If there are jumps, phases may
change by more than n within the domain of synchronization. Furthermore, there
exists a domain with stationary phase values. The theoretical investigation of
a concrete generator scheme (n - 2 and n - 3) confirms the conclusions derived
here. On the occasion of a thorough investigation of the case n - 2 the existence
of a "threshold value" of a certain parameter was furthermore found, in the case
of which further jumps are possible.
The block scheme of the experimental order is givenj in the cathode repeater it
contains a circuit which is tuned in to the frequency of the eigenoscillations of
t'--V generator to be synchronized. It is thereby possible, in the spectrum of the
exterior force, to suppress the harmonies with a frequency that is near the eigen-
frequency of the generator. Synchronization was carried out at frequencies of the
exterior force 6)e - p/n (n - 2,3,4,51 P , Wo, Wo - frequency of the generator,
and showed that synchronization takes place on the subharmonic at arbitrarily
small amplitudes of the exterior force. If the amplitude of the exterior force is
increased, the breadth of the synchronization band increases non-linearly.

Here all the coefficients are positive, p no vo, P = Zdw2-0, and BO

the form of a Fourier series. A system of algebraic equations is
obtained-relating the system parameters, the external force, and

which takes into account n harmonics of the synchronizing oscillation
with an external periodic force that also contains n harmonics. Here
the values of Am are determined in terms of the system parameters and
the Fourier coefficients, and A is the angle between the fundamental
frequency of the synchronized self-oscillation and the mIth harmonic.
The first term of the equation takes into account the indirect effect
of the external force of the frequency., resulting from the change in
the spectrum of the free oscillation. The second term takes into ac-
count the direct effect of the external force on the conservative
parameters of the self-oscillating system, determining the frequency.
The above equation leads to many known self-excited phenomena.
