TITLE: Carborundum Products With Silicon Nitride Bond
PERIODICAL; Ogneu-pory, 1960, No, 4, PP, 175-180
TEXT: The properties of these carborundum products are investigated and
described by the authors in the paper under review. Silicon-nitride (Si 3N4)
melts at 1900 0 ana may be used as refractory materials Its strength scarcely
changes in the temperature range of from 20 - 12000. A number of patents has
been granted lately for the use of silicon-nitride as bond for the manufacture
of high-quality carborundum refractories, The charge oomposition and the
properties of the carborundum samples with silicon-nitride bond are mentioned in
table 1. In the course of the determinatiur, of refractoriness, the py~7oscope of
metallic eilicon was deformed at a temperature of 16800 and that of a sample of
100~ technical silicon, previously nitnted at 1500 0; at over 19000 (Fig- 1).
The proplerties of tha samples are compared in table 2, The influence of the
carborundum granulation and of the amount of silicon on the ceramic properties of
the samples may be seen from table 3. The thermal expansion of the carborundum

samples with silicon-nitride bond is shown in Fig. 2. The oxidizability of the
carborundum samples in air at 16000 is mentioned in table 4. The authors state
in conclusion that, as a result of the investigati 8, the manufacturing
technique of high-quality carborundum refractories%ith silicon-nitride bond
was worked out, its advantage consisting in its constancy against influences
of acid and slag. There are 2 figures, 4 tables, and 20 references, 4 of which

TEXT: The authors carried out hot-preasing on an installation deeigned
by the Institut metallokeramiki. i spetsiallnykh splayov AN USSR (Institute
of Powder Metallurgy and Special Alloys AS UkrSSR), Experiments showed
that an addition of 20% boron results in a considerable increase of dens_`V
(Table 1) when pressing the carborundum at 2200'C. The porosity is ntill
high at a pressure of 100 kg/cm2 and a temperature of 20000C (Table 2),
Reducing the pressure below 100 k9,1cm2 leads to an increasq in porosity
(Table 3)~ The compression of the samples continues during temperature

C TAGS: self adaptive control, frequency characteristic
ABSTRACT: The tuning dynamics of self adjusting control systeM3 with stabilization of
the frequency characteristics were analyzed by considering the effect of the program
steps, including jump instructions and interferences in the main loop. The main loop
is defined as the contro.]. circuit including the plant, the final control and parallel
adjusting elements without the tuning circuit. The differential equation of the main
loop was developed and solved. The equations of motion of the.system with stabiliza-
tion of one point of the flrequency gain characteristic of the open-loop system were de-
rived. A specific example of determining the tuning dynamics of a system with control
of the frequency gain characteriptic is included. Crig. -art. has: 9 figures, 85 form-

ABSTRACT: The analysis of dynamic performance in self-adjusting Systems with frequen-
cy stabilization using -linearized transfer functions with respect to the choice of the
measuring element is reported. In particular, closed and open loop systems are con-
sidered: those utilizing bandpass filters and r-ectifiers 'to extract the required fre-
quency components in order, to compare their magnitudes with -the desired values and
those based on autocorrelation operations. The autboi.,s call -the first type "additive"
and the second type "multiplicative" i Both use ei-thater rpecial harmonic input signals

response characteristics or extract these signals from the normal input to the system
by means of narrow band filters. The transfer functions for both types of self-adap-
tive systems aie derived for steady state and transient responses. These equations
are subsequently "linearized" and used to compare performance of the two systems. The
authors conclude that the self-adjusting pracesses are the same in both systems if a
filter, having transfer function identical to that of tile-bandpass filter used in the
additive system, is; included in the multiplicative system after the multiplier and if
all other linear elements are also identical. Since smoothing filters theoretically
cannot be used after the multiplier, the multiplicative system should have faster re-
sponse but a higher noise level. However, if lead networks are used to compensate the
lags lin the additive systems their performance can be made for practical purposes iden-
tical to that of mu.1tiplicative systems. An example is included in which the perform-
ance of the two types of self-adaptive systems are analyzed and compared. Orig. art,

ABSTRACT: Self -adapting auton-iatic-control systems that vary their own fre-
quency characteristics were studied by A. A. Krasovskiv et al. (Fundamentals
of automation and technical cybernetics, published by YVIA im. ghukovskogo,
1961). The self-resetting method considered in the article includes stabilizing a
few points on the amplitude -frequency characteristics of the open and closed
automatic -control systems. Hence, the values of these characteristics at some
fixed frequencies verve as indicant6 of resetting. The law that governs the

correcting circuits is formulated thusly: The signal of difference between the
measured and the required resetting quantities is fed, through an integrating
circuit, to a var iable -coefficient -generating unit and varies the coefficient until
the difference signal vanishes. A number of functional diagrams are discussed
and analyzed mathernatically. The above theoretical work amplified by an
"investigation of u laboratory model of an industrial controller" permitted the
formulation of the iundamez.-tal properties of the self-adapting systems. Orig.

ABSTRACT: Tests are reported designed to examine the effect of a
lubricant introduced between the joint faces on the
consistency of the tightening of bolt connections
subjected to prolonged alternating loads. Different
micvo-geometries, of the butting surfaces were tested.
In the test Riga a Plummer block housing was bolted to
a sole plate with 10 mm bolts of steel 45. The
components were made of cast iron. The pre-tension
and its relaxation were measured by strain gauges
arranged in a d.c. bridge. An alternating stress
amplitude of 500 kgi--2 in the bolts and

strain gauges. The pre-tension amounted to 1000 kg/cm

The Effect of Lubrication on the Consistency of Tightening of

Its change during 12 hours of alternating load
applied at 2900 epm was checked each hour. In a
family of curves, th6 drop in the bolt pre-tension
is plotted against the ntunber of alternating cycles
for different surface finishes and in the presence
or absence of lubricant3 in the joint. The graph
shows the greatest drop of pre-tension to occur
with the coarsest surface and with lubricant.

TEXT: Ultrasonic thickness measurements of pipe walls by means of a-B4--BP
fIV4-8R) apparatusrequire a complicated preliminary treatment of the epee,-
men surface. Therefore, an eleetroinduction thickness gage was construct-
ed which makes it possible to measure the wall thickness of austenitic
6 - 15 mm-steel pipes. The apparatus consists of an audio-frequency genera-
tor, an amplifier, a phase detector, and a separator. The generator operates
with 550 - 3500 cps, 4 w, according to the thickness of the wall. The speci-
men is placed before the first pickup and the standard before the second.
The primary windings of the pickup are connected in parallel and the sec-
ondary windings in the opposite direction. As long as the specimen com-
plies with the standard, 'the emf in the secondary windings is equal to zero.
With different values of specimen and standard, the emf produced in the
secondary winding is increased. An instrument indicates the difference,

no. 6, 19619 21-23
TEXT: The Ukrainskiy nauchno-issledovatellskiy trubnoy
institut ( Ukrainian Scientific Research Pipe Institute) has deve-
loped an apparatus fer automatically checking the wall thickness
of pipes during production. It consists of a thickness gauge and
an automatic checking block. The thickness gauge is based on the
Eddy current and can detect differences of wall thickness of a
pipe round its perimeter and along its length. It has a short
time lag which is important when the signal caused by a difference
in wall thickness is short and when it is necessary to transmit it
quickly to a recording mechanism. Its recording mechanism can be

used as a part of the thickness gauge for checking the pipes manu-
factured from a non-magnetic material. A standard pipe made from
the same material as the measured one is used by this apparatus
for detecting the difference in wall thickness. This thickness
gauge indicates the difference in wall thickness by means of a mid-
scale zero ammeter calibrated in microns and connected to a finger
type detector. The automati,~ checking block switches off the
engine moving the pipe into the gauge by means of the light signal
when the deviation from the wall thickness is bigger than the given
tolerances. Since the thickness gauge detects the positive and
negative sign of deviation of the wall thickness then the automatic
block circuit has two pulse height discriminators, each of which
is designed for emitting the signal of specific polarity. The
circuit can be adjusted for differenit" values of the threshold vol-
tage for each discriminator. Potentiometers R 10 and R21 are used
for signal limitation by means of a discriminating voltage. Pulae

height discriminators are tuned on crystal diodes Dl, D21 D 3 and
D4. To express clearly the threshold. of discrimination the opera-
ting-point should be on the rectilinear portion of the diode chara-
cterictic, and direct current amplifier3 in the form of semicon-
ductor triodes'O I and 1~12 are connected before the discriminator.
The bigger the coefficient of cascade amplification, the shorter
the signal and smaller the accuracy of the automatic block. For
this automatic block, the accuracy is 2-35,46. The source of supply
should be stabilized to keep the magnitude of the threshold vol-
tage and the amplifier supply voltage constant. The lamp L 32 Fig.1
indicates the supply voltage to the -thickness gauge. When the'
deviation from the wall thickness is bigger than the giver. tole-

TEXT: The magnetic flaw detector (Fig.) describad in this paper is based
on the magnetic suspension method, and is used to test a soft-magnetic
metal coating 40 to 100p thick, applied to nonmagnetic steel by hot -
rolling. The device consists of d. c. operated electromagnets 1 and.2
each composed of two cores and having a common shaft 3 which is fixed to
test table 4, bCA (VSA)-type rectifier 5 with a rectified voltage of 24 v.
container 6 capacity ,05 liters, equipped with a pump, special supply
duct 7, illuminator, and flexible rubber hoses for circulating the sus-
pension. The electromagnet coils have 1700 turns of the wire g35 (PEL),
1 mm in diameter, and are contained in an aluminum housing. The current
in the coil was controlled with an ferro-resonance voltage controller.
Products are tested in a magnetic field of 70 to 130 oe. The suspension
is pumped to the test article, passes round it and is returned to con-
tainer 6 through connecting pipes and an outlet in the test table. The

test specimen is attached to ,;he test table with holder 8,- the test
articles are either brought to the test table by hand or by device 9.
Experience has shown that if ';he sensitivity of the device is so high
that scratches 10 - 15,P deep can be detected, "imaginary" defects would
be recorded. With a coating up to 50)t thick, bands of the precipated
BUSDension form in the case of defects, and disappear again when the
seneltivity of the leak detector is lowered. The maximum sensitivity for
a flaNy detector used on magnetic metals 30 to 50~L thick is a depth of 20~L.

authors (Atomnaya energiya, 11, 565 (1958)). The neutrons with 3 and 15
Mev were obtained from the reactions D((I,r.,)He3 and T(d,n)He4. respectively.
The mean errors in the measurements wert! 7 and 15~. The great difference
in the cross sections at 3 and 115 !!;v ii-, the caae of light nuclei is
explained by the relatively greater scattering anit3otropy on light nuclei
with increasing energy. There are 2 figures, 2 tables, and 17 references:

ABSTRACT: - The passage of )r rays through a barrier was studied as a function of the angle,
of incidence, varying the angle between the barrier surface and the Y-ray beam between
0 and 80% The barrier material was either lead (r 0.7, 0.8, 1.4, and 2.75 cm), lucite
(r = 3, 8, 11 and 14 cm) or a combination of lead (r 0. 8 cm) and lucite (r = 8 cift.), where
r is the barrier thickness. The source of 2r rays was COGO (1 curie), and the detection
system consisted of a stilbene crystal (r = 30 and h = 15 mm), an FEU-12B photomultiplier,
a cathode repeater, an amplifier (Siren type) and an impulse integrator. The results are v
plotted. Fig. 1 of the Enclosure shows the dosage behind a combined barrier of lead and
lucite as a function of the angle of incidence. The total error in the measurements was

estimated to be of the order of 5 -10%. These experimental results were then compared
with the theoretical calculations of Berger and Doggett, (J. Res. Nat. Bur. Standards
56, 89, (1956)) for perpendicular beams and with the calculations of G. H. Peebles
(Repoit R-240, the Rand Corp., Santa Monloa, California (1952)) for other angles of
incidence. The experimental data were, In good agreement with the theoretical.
