A13STRACT: In.'the paper under-review the authors give data concerning
their work during 1947 in the field of the preparation of
liquid polydiethylsiloxanes from diethyldiethoxysilane and its
mixtures with triethylethoxysilane. It was the objective of
this work to synthesize polymeric liquids free from iMDUrities
of those polymers which contain ethoxy groups in the molecule.
The hydrolysis of diethyldiethoxysilane in an aqueous medium
at 1000 resulted in the formation of the diethyldioxy- and
oxyethoxysilanee which, in turn, were transformed into'po
diethylsiloxanes of cyclic and normal str~dturea-,(Scheme

the ethoxy group (~) in the molecule coi~ld not be avoided. The
synthesis of polydiethylsiloxanes free from ethoxy groups on
the basis of the hydrolysis products of diethyldiethoxysilane
was carried out by means of a reaction with 93-100% sulphuric
acid at 20-500 as well as with 95-99% formic- or acetic aoid'.
at 60-1000 according to scheme (II). When sulphuric acid was
used the fractional composition of polydiethylailoxanes changed
abruptly toward the formation-'of.polymers of a higher average
moledular we'ight ("Scheme III). The carboxylic acids did not
cause a regrouping of the cyclic polymers (Scheme II, Table 1).
On the basis of what'has been reported so far it was possible
to assume that the synthesis of polydiethylsiloxanes free from
polymeric impurities containing ethoxy groups in the molecule
by the action of concentrated acids (esp. sulphuric acid)
,upon diethyldiethoxysi,lane foll4s the general scheme (IV)

ABSTRACT: In continuation of the preceding paper NOC 1959929pl2TO) the
data concerning the reactions of phosphoric- and boric acid
with ethylethbxysilanes are described in the present article.
It was shown that, like sulphurio acid, phosphoric acid react-
ing with diethyldiethoxyoilane results in a formation of poly-
diethylailoxanes free from impurities of normal polymers with
ethoxy groups in the molecule, and in the formation of acid
ethyl phosphates. This formation is brought about at a molar
ratio of diethyldiethozycilane to the acid of 3:2 up to 1:2.

With Triethylethoxysilane
oulphuric acid (Scheme I) the'reattion with phosphoric acid ex-
hibits an intermediate stage in which polydiethylailoxane phos-
phates formI'which are stable in the middle of the-reaotion &a-
cording to scheme (II). If water influenoes the reaction pro-
duot, a hydrolysis of the phosphates accompanied by the separa-
tion of polydiethylsiloxanee and acid ethyl phosphates takes
place according to schemes (III).and (IV). It proved impossible
to remove the polydiethylailoxane-phosphates since the distil-
lation of the reaction material resulted in their decomposition.
Their presence was proved in three ways. The date obtained sup-
port the assumption that two kinds of polydiethylsiloxane phos-
phates are present in the reaction product (Scheme 11). In the
hydrolysis (Scheme III) it may be seen that polydiethylsiloxane
phosphates exhibit a polymeric grouping an soon as the acid
ethyl phosphate,is split off. A further condensation results in
non-distillable polymers of high molecular weight. In this hy-
drolysis (Scheme IV) individual polymer components, the cycli-
zation of.which results in low-boiling products, liberate them-

is also the case with sulphuric acid. The reaction with boric
acid in place of phosphoric acid takes place in the same way
(Schemes VIII and IX). The fractional compositions of the poly-
mers obtained by the reactions of both acids are similar. There

the C6H5:Si ratio were calculated# and for some samples the microeLemental andly-
sin of the.RIC ratio was also carried out. It was found that the thermo-oxida-
tive degradation of the resin without a catalyst leads to weight lose exceeding
even the theoretically possible losses obtained by the combustion of the entire
organic part of the resin. The process of degradation is accelerated consider-
ably by potassium hydroxide and acetate. The data obtained with inorganic cata- I

gated by weight loss. The weight loss data at 400C show that their addition
affects the thermo-oxidative degradation to a certain extent. Hydroxides and
salts of alkali metals are very dangerous agents because they accelerate the
oxidation of the polymer. The mechanism of action of these catalysts has not
yet been clarified,-but the experimental data show that the purity of the poly-
organosiloxane has a significant effect an their activity at high temperatures.

ABSTRACT- This paper gives an account of the principal results of
an experimental investigation carried out in summer
1957 (on 3 weekdays and on one Siuld1W) in the Ob"yedi-
nennaya energosistema Tsentra (Combined Po7er System oftin
Center). It covers: 1) An investi~~ation of the frequency
fluctuations in a non-controlled power system. It
appeared that the irregular frequency fluctuations
in a large power system are relatively small ( not
exceeding 0,2%) and that with a relatively stable
load in the power system (this implies only slow
frequency variations) the usual requirements placed
Card 1/3 upon frequency maintenance on a certain level are

satisfied even without automatic control. 2) An
investia.-tion of the frequency fluctuations with
automatic frequency control, even with the help
of a relatively powerful stationAdoes practically
not at all reduce the amplitude of irregular
fluctuations. In some instances, in particular on
Sundays and during night hours such fluctuations
became apparent in a much hiCher de-ree in an
automatically controlled system than in a system without
control. 3) Examinations of the total load variations
in a power system. This study showed that the load
varies very irreaularly. When the load showed a
general tendency to rise it rifdenly dropped back
and vice versa. 4) The rlep SUlt4y;j static behaviour of all
units of the power system, except of those of the
Volzhakaya GES (Volga Power Station) remained within
the limits of 6-10%. 5) A determination of the slope
of the static frequency yersus load characteristic.
It was found that the volta.rpe in the 110 kV-grid of

ABSTRACT: This Author Certificate.presents a multi-support stand with frame supports
for,plaoing of ship so ctions'.. To mechanize tNe- cing of the supports under the
ship sections, the frame supports are pivoted below the floor level and are kine-
-matical,3.y-connected to the push rod of a bydraulic~cylinder which synchronously lifts
the supports to a vertical position and lowers them to a horizontal position until
~the.back sides of the supports are at floor level and form a flat platform (see Fig.

TEXT: The article describes the results of -invest-igation-z -ar.-Ied
out on the wear resistance of grey cast iron, steel and metal-Ir'-,
ceramics. Various conditions of sulphiding, such as temperature
and media, were kept identical in all cases. The experiments --cn--
cerned vaive pairs. The spools were made of -fZXH3A ( 12KMA), -.,&
XFGA (30KhGSA) and 4OX' (40Kh) steel, the sleeve of 30KhGSA slt--ael~
Parts of valves were subject to sulphiding after grinding. Tho~7e
made of 30KhGSA and 40Kh steel were treated in an EMS bath of
72% K4Fe(CN )61 10% Na. 2S203 and 18% of NaOH. During wear tests, use

by K13-/l(KV-7) profilometer which indicated that the former d-~:, nc-
change. The diameters were inspected in two perpendicular planes on
a horizontal optimeterWKF(IKG),, for the spool, and by a pneumat--_-
instrument f7flo-.9M (FPO-9M) for the sleeve. The graphs af re31-;!-,.=
show minimum wear in the non-sulphi.ded spools; the greatest wear
was found in sulphided steel- 40Kh, and the least by 12-KhKA CCMn,-\_
nents. The wear of sleeves working with sulphided spoole il=_ re-
duced by half. The sulphided spools in 40Kh steel. showed a su-'rhur-
saturated layer. Some cyaniding takes place in the ENIMS bath due
to the presence of CN. The publication of promising resultF c-n the
increase of wear resistance of metallocermaics by sullphiding in

Central Asian Polytechnic Institute to investigate thiss problems
Sulphiding was made by two methods; in sulphurouz iron and annea1_1
ing with S. The components were iron graphite bushes cf variGus
consistencies. Microscopic examinations revealed that the sulphur
inclusions are uniformly distributed in the mace of the workp:.e,_--e,

with orientation around grains. The bushes were cut into rollers
and turned in order to test them on friction, wear and running-in
qualities. The anti-scuffing properties were determined by checking
wear without lubrication, The graph of results indicates no re-
duction of wear due to sulphiding, when measurements were made
with a passameter. Finally, tests were made for machinability de-
termination, with simultaneous measurement of wear, by the method
of Professor M. M. Krushchov. The results are tabulated, and they
reveal that the sulphided components are run-in faster than the
non-sulphided workpieces. The former also exhibit lower friction
force and operate more steadily. The table demonstrates that the
sulphur additive promotes greater wear which is contrary to pre-
vious investigations. Sulphiding may be recommended in cases where
the main requirement is anti-scuffing property and not the wear
resistance. There are 2 ficures, 4 tables and 8 references: 7 So-
viet-bloc and 1 non-Soviet-bloc. The reference to the English-lan-
guage publication reads as follows: F. D. Waterfall, Reducing
scuffing and wear of ferrous metals, Surface treatment by sulfi-
nuz process. Engineering no. 4846, 1959, 197.

TEXT: An investigation was carried out as to the properties of the metal
in the zone of thermal effect in steels 30,Y1_CA and 30XFCHA (30KhGSA and
3011,aGSNA) with the aim of choosing the best heat-treatment schedule,after welding,
under which the structure would poEsess high strength, sufficient ductility and
would completely satisfy all the technical requirements. 5 Mm. thick steel sheets
subjected to isothermal hardening prior to welding were used as specimens. After
the hardening,some of the sheets were butt-welded and building up was carried out
upon others. Some of the specimens were tested without tempering after the
welding, and the remaining ones were subjected to tempering at various tempera-
tures; Conclusions: 1) For welded bearing structures of steel 3GKhOSA it is
necessary to carry out a tempering at 520i-100C after the welding. In the fabrica-

tion of nonbearing parts, for which Tb _x~80 kg/mm2, the tempering need not be
carried out after the welding. 2) For welded structures of steel 3OKhGSNA a
tempering at 300i-100C is obligatory after the welding. 3) The tempering duration
for welded sti-actures of steels 30KhGSNA and 30KhGSA should not be less than I
2 hours, since a reduction in the soaking time will not yield the maximum Tb.
4) Tempering of welded structures of steel 30KhGSA and 30WSNA can be carried
out at any time after the welding, but necessarily before putting the structure
,KWSNA for structures
into service. 5) In choosing either steel 30KhGSA or 30'
which may be subjected to repair by welding in the process of service, it is
nesessary to take into account the possibility of tempering after the welding.

ABZPrRAOT addition of TiO2 has a marked harmful effect on
the crystal structure of the glass along with
producing some improvement in the fusibility of
the glass The addition of ZnO has almost no ef-
fect on t;e liquidus temperature; the rate of
crystallization is'Markedly Lncreased. The
substitution of L:L;-O for 1% of the RO at 400 and
for 6 same amount of % 0 at 250 results in a
