PERIODICALs Zhurnal obahchey khimiiq 1960t Vol,, 309 No. 69 pp. 1968-1971
TEXTR The properties of bia(hydrory-methyl)-tetramethyl-disiloxane were
investigated to find out whether the universal esterification methods may
be applied to this compound. The stability of this compound was investi-
gated by changing the conditions of synthesis. Bis(hydroxy-mathyl)-tetra-
methyl-disiloxane was obtained from bie(acetoxy-methyl)-,tetramethyl-
disiloxane by treating it with methanol in the presence of EC1 (for
72 hours at 200). The methyl acetate resulting in addition to the former
and the excess of methanol were distilled from the acid reaction mixture
or from the mixture previously neutralized by means of sodium bicarbonate.
The content of hydroxyl groups and Si in the compound remained unchanged
both in the neutralized reaction mixture and in the compound distilled
off; both were stable for four months (no change of visoosityq no water

separation). The bia(hydroxy-methyl)-tetramethyl-disiloxane thus obtained
was esterified with metbacrylic acid chloride and allyl formic acid
chloride. The reaction schemes are given. The starting material + allyl
formic acid chloride gave bis(carbox -allylate-methyl)-tetramethyl-di-
siloxane (yields 30%), whereas the ru..otions starting material + allyl
formic acid chloride + methacrylic ac.1 chloride led to 1-moth" crylate- kA
methyl-2-carboxy-allylate-methyl-tetramethyl-disiloxane (yield: 19%). The
poor yield is explained by the considerable tendency of the reaction
products t9ward further polymerization. Polymerization with peroxy
initiators proceeds very smoothly. Bolidq vitreous polymerslare formed.
The properties of the substances synthesized are tabulated: The reactions
are described in detail in an experimental part. There are I table and
1 non-Soviet reference.

ABSTRACT: In this investigation the authors synthesize (chlorom ethyl)m ethyl-
phenylchlorosilane from (chlorom ethyl)m ethyldich loro si lane and bromobenzene
by Grignard's reaction. The yield of distilled (chloromethyl)methlphenyl-
chlorosilane was about 50% of the theoretical. This compound usually reacts
with ethanol to form (chloromethyl)methylphe-iylethoxysilane. The beat yield of
the new compound, about 90% of the theoretical, was observed when the reaction
took place at room temperature. The reaction of (chlorom ethyl)m ethyl-
phenylethoxysilane with potassium methacrXlat~yielded (methylm ethacrylate)m ethyl-
phenylethoxysi lane. Its yield was 30916 of the thdoretical. This compound can be
polymerized along the double C-C, bond and enters into a condensation and cocon-
densation refraction owing to the presence of the ethoxy group at the silicon atom.

investigated# The reaction will go in the absence of solvents, but it
proceeds more readilyp giving high yields at lower-temperaturess in the
presence of catalytic amounts of HC1 or organic acids. The proposed
reaction mechanism -- formation of an intermediate reaction product with
the acid catalyst and decomposition -of this oxonium compound by beating
-- was confirmed experimentally, The following now compounds were

4BSTRACT: The most common cause of failure of steam and water
turbines is damage to the blading, usually by fatigue.
It is usually supposed that most of the trouble is caused
by vibration, and that the main causes of vibration are
inequalities in the flow of the working medium. These
propositions are generally true and they have been used
reatly to reduce the amount of damage suffered by blading.
K
ey are, however, incomplete. Experiments carried out on
blading of stages which had been subject to frequent fai-
lures showed that the natural frequency of the blades was
different from multiples of the speed of rotation. The
blades were found to vibrate only with certain conditions
of generator load. Analytical investigations showed that
Card with some asymmetrical loads on the generator the torque
1/4 could be very complex. It was, therefore, of interest to
determine a mechanism by which blades are set in vibration

by forces acting on the generator rotor, and a special
investigation for this purpose was made on a model from
which, however, it was only possible to determine the
mechanism of energy transfer. Experiments were then made
on a dynamic model of a power system designed and manu-
factured in the Moscow Power Institute (MEI) under the
gitidance of Prof. V.A.Venikov. The object of the experi-
m,~nt was to determine the spectrum of the torque for
various operating conditions of the generator and to eluci-
date the influence of transitional conditions of the gen-
erator on vibration of blades.
The experimental procedure is then described. The torques
v;ere measured by strain gauges fixed to the shaft between
the generator rotor and tile turbine. Measurements were
n,ade with symmetrical and asymmetrical change in the
rorking conditions of the system. Comparison of the torque
'In the two cases gave information about the cause of vib-,
ration. The second series of experiments was made to
determine the vibration of blading during transitional
Card :)rocesses in the electrical part of the system. In this
2/4 case blades were installed on a special disc between the

asymmetrical currents in the generator. (Cont.)110-7-6/30
generator rotor and the turbine. These blades were not
acted upon by the working substance and their vibration
was caused only by forces applied to th6ir roots. The
blades were designed to resonate with harmonics of the
generator torque under asymmetrical conditions.
The measuring equipment is described. The oscillations
of shaft and blading were measured by resistance strain
gaugesq amplified and recorded on an oscillograph. The
circuit of the model transmission line is given in Fig.2,
its parameters correspond to those of the Kuibyshev Power
Station and the Kuibyshev to Moscow transmission line.
Two series of tests were made to determine the nature of
the changes in the elastic torque. These were three and
two-phase short circuits. The corresponding osci-Ilograms
are given in Fig.3. These show that only asymmetric short
circuits cause a periodic component of torque. Fig.4
shows oscillograms of blade oscillation with a natural fre-
quency of 100 c/s which shows that even under normal con-
Card ditions the blade oscillates at its natural frequency, but
only with small amplitudes. The amplitude is greatly in-
3/4 creased by two-phase but not by three-phase short circuit.

is greater but principally the equations will not differ
from the given ones. The higher frequency of the rotor of
a hydraulic generator can be determined If the distributed

TITLE: -AH--A-n-a-1`ys`1`-s--oT-Blade Failures of Hydro-alternator Fans
PERIODICAL: Izvestiya vysshikh uchebnykli zavedcniy, Elektromekhanika,
1959, Nr 10, pp 137 - 145 (USSR)
ABSTRACT: This article discusses the causes and effects of vibration
on fan blades in altbrnators. Damage to fan blades occurred
on 66-b1W alternators of Swedish manufacture; the blade
design is illustrated in Figure 1. The blades failed at
the notch, above the root, and were replaced by new ones
without notches, which have since operated satisfactorily.
Tests were made at the Khar1kov Polytechnical Institute
to fiiid the causes of the trouble. Determinations wero
made of the natural frequency of the blades and the shape
of the vibrations and of the stresses incurred by machining
the notches. The test equipment with a blade in position
is illustrated in Figure 2. Strain gauges were fixed to the
blades at the positions shown in Figure 3. It was found
that the fundamental frequency of the blades was about
100 c.p.s. and that the effect of the notch was to cause
Cardi/4 a stress concentration of 2.45 units. The centrifugal

stress was not greater than 200 kg/cm, which is quite safe,
so that the blades could not have failed through static
stressing. However, since the natural frequency of the
blades was about 100 c.p.s. and the fractitres were of
fatigue character, it is reasonable to supl)ose that the
cause of the Ault was a periodic component of the
alternator torque.
In a previous work, the author has shown that there is a
100-cycle component in the torque if the current loading
of the alternator is not symmetrical but in the present
case, the symmotry, if any, was small. In order to
evaluate the 100-cycle component of the torque, tests
were made on a large hydro-alternator. Two rods each with
a natural frequency of 100 cycles were fixed to the
coupling on the turbine shaft and their vibrations were
recorded by means of strain gauges. A schei:iatic diagram
of the arrangement is shown in Figure 4. Oscillograms of
the strain-gauge readings were taken at various alternator
Card 2/4 loadings and the 100-cycle stress in the rods was calculated.

SOV/144-59-10-15/20
An Analysis of Blade Failures of Hydro-alternator Fans
The method of calibrating the rod is explained and
torque oscillations of the rotor %iore determinod. The
tests on these large hydro-alternators showed that even
a small current asymmetry of the order of 2*50,o can
set up appreciable stresses in parts fixed to the rotor.
Of course, the test rods were fixed to the coupling,
whereas the blades that failed were directly attached to
the generator rotor; therefore, a special model was
made up to investigate combined oscillations of rotor
and blades. It consisted of a heavy disc on a short shaft
running freely between ball bearings. Four rods were
fixed to the disc to represent the fan blades. Oscill-
ations were set up by light taps, applied in a tangential
direction (ither to the disc or to the rods-and were
recorded with strain gauges. Formulae are derived for
the oscillations,and their values, as calculated from
Eq (9), are compared graphically with the recorded
oscillograms in Figure 5. It will be seenthat agreement
is good. These tests and calculations indicate that

TEXT: The authors studied the power conditions for rolling at the thick-
phept mill 2800 of the Plant imeni Voroshilov. The mill is designed for rolling
sheets with thickness 6 .50 mm, width 2,500 - 2,600 mm. It consists of a stand
with vertical rolls, a roughing two-high stand with working rolls 1,150 mm dia,
a universal finishing four-high stand 800/1400. The stands are arranged in a
sequence. The roll separating force of the metal.in the roughing and the finish-
ing stands Was measured by means of force meters with wire tensometers. The
force meters were welded to the pedestals of the working stands on the side of
drive. The pulses from the tensometers were recorded by a magnetoelectric os-
cillograph NOB -14 (POB-14). A calculation of the forces from the torque was

1) the separating force of the metal on the rolls of the four-high stand is, In
all the cases investigated, below the admissible; 2) the closest agreement with
the experimental data is given by the values of the mean pressures as calculated
by the GolcvIn-Tyajrunov method; 3) the main motors of the mill 2800 are not
utilized to full capacity. -

T M The author investigated experimentally the metal pressure on the
rolls, voltage and revolution of motors when rolling on blooming and sheet rolling
mills, In order to intensify and rationalize reduction conditions. It was found
that when rolling sheets on a 2250 mill, the force in various passes fluctuates
within 889 - 1,895 tons. This causes non-uniform motor loads and increases un-
dulation and corrugation of the sheets. The author determined the dependence of
metal pressure on the rolls on temperature during the rolling of sheets of differ-

the efficiency of the sheet rolling mill by 5 - 10% and that of the blooming mill

A13STRACT: The thickness of a nickel interlayer plays a major role in promoting
or inhibiting diffusion processes at the boundaries of metal joints and affects the
properties and structure of the boundary zone. To determine this effect with
respect to the strength of the joint and the structure of the bimetal, investigations
were carried out on specimens made from laboratory and industrial clad steel.

The laboratory test pieces were made of rolled packs of Khl8Nl0T and St. 3sp
types of steel with and without nickel interlayer, the thickness of the interlayer
being 10, 25, 40, 65, and 90 microns. The tests were conducted for shear and
tensile strength, notch toughness, cohesion strength, metallographic investi 'rations,
and spectrum analysis. The industrial test pieces were made of 10-14-min-thick
clad-steel sheets with a cladding layer of Khl7Nl3M2T steel, and basic layer from
20K type steel wtithout ant with nickel plate of a thickness of 25-30, 40, 50, G5,
and 90 microns. The cohesion strength of both laydirs is found to increase as tile
thickness of the nickel interlayer is increased. The latter also affects diffusion at
the metal layer interface and as a result tile hardness and microhardness,as wellaE
changes in the concentration'df alloying elements. The maximum carbon consentra-
tion is found to be inversely proportional to the thickness of the nickel interlayer.
The same is observed with respect to carbon diffusion. In steel clad without inter-
layer, there occurs complete decarbonization of th e' boundary layer of the non-
carbon steel. A nickel interlayer lowers decarbonization of the boundary layer of
St. 3sp steel and hinders the enrichment of the cladding steel in carbon.

experiments were carried out at the stage of the optic
vesicle (25-26 stage~according to ref. 2). The
mesenchyme was easily removed from the vesicles, whereafter
33 vesicles were homoplastically transplanted: I. Series -
into the pericardium cavity and into the body cavityl II.
Series - under the skin, into the gill cavity and to the
somite of the embryos of the same age as the donor. In the
first series the grafts should be missing mesenchymic
surroundings, in the second series, however, be completely
surrounded by it. The eyes of the graft carrier served
as control (fig. 1). They are described in full detail.
Results of both series of experiments are illustrated in
table 1. They make it possible to draw some conclusions:
1. The eye rudiments of the said st e9 (eye vesicle) are
able to develop in the ordinary wayefformation of a 2-
-layer eyecup, of a pigment epithelium and of a retina) as
well as to be transformed into a single layer by entirely
becoming a retina. 2. For a normal development of the eye

is necessary that the eye rudi-nerit--i-s surrounded by the

eye rudiments develop entirely into a retina. These data
achieved with sturgeons agree with those of the amphibia
and mammals (refe- 4-7,9). The kind of '- meeenchymic
surroundings be&ivinfluence on the character and the degree
of pigmentation of the pigment epithelium. Finally the

ABSTRACT: At the time of their formation (optic' vesicle stage) all parts
of the eye rudiment of Acipenseridae can develop as well into
the retina as into a pigment epithelium. The formation of the
l.atter occurs if the-optic vesicles are enclosed by the mesen-
chyme (Reif.2). In this respect the eye rudiments of Acipenseri-
dae-do not differ from those of amphibia (Refs 5,6), birds
(Ref 9)-and mammals (Ref 8). The question is still unsolved
within-what lapse of time the material of the ectoderm can
change into the retina and that of the entoderm under altered
conditions of development into pigment epithelium. In order to
solve this question experiments were made on the embryos of
Acipenser gueldenstaedti and of Ac. stellatus. In the Ist
series of experiments whole optic cups were transplanted into
the pericardial cavity. In the IInd series of experiments the
inner layer of the optic cup was transplanted under the ecto-
Card 1/13 derm of the head, in the region of the auditory vesicle so

that it was completely enclosed by the mosenchyme. From the
results"of the IBt and IInd series (Fig 1 a,b, 1 v) it becomes
evident that the eyes of Acipenacridae (just like those of
amphibia) early loose the capacity of redifferentiation of the
retina (Ref 3). In the IIIrd series of experiments the inner
layer of the optic cup with the lens was transplanted into.the
pericardial cavity, where there is no free mesenchyme. All
grafts developed into retina..With respect to the lens,the
layers of the latter were normally oriented* This series can be
considered.as a control of series II. In the IVth series tht.-
outer layer of the optic cup was as far as possible cleaned of
mesenchyme cell8,-segmented'off, and transplanted into the
pericardial cavity. In that case all layers of the retina were
also developed. The photoreceptors were oriented towards the
pericardial cavity. The results obtained show that both in the
stage of the optic vesicle and of the optic cup the eye rud-'-
ment isstrongly influenced by the surrounding mesenchyme. Out-
side of this influence pigment epitheliu-m is never formed and
the eye rudiment is able to develop entirely in the direction
Card of the retina. In this respect the eyes of Acipenseridae are

SOV120-1 2'--4-70/7,;
Regulatory Properties of the Eye in the Embryou of Acipen3eridae
similar to those of amphibia (Ref 6) and differ somewhat from
those of mammals, where this rule shows certain exceptions
(Ref 8). The capacity of the retina to form pigment epi-
thelium is already markedly reduced at the moment before it
separates into layers, as this is the case in amphibia and
birds (Refs 3,9)o However, the pi6ment epithelium is still
capable of changing at this stage. If mesenchyme surroundings
and blood are lacking it becomes the retina. In this respect
the eyes of Acipenseridae are similar to those of ampidliap
birds, and mammals. There are 1 figure and 11 references, 8 of
which are Soviet.
