ABSTRACT: A telcinctoring system which is required to monitor and transmit data from
many sources is most economical when many monitoring sensors are used in connection
with one measuring and transmitting system. A block diagram of such a system is shown
in Figure I of the Enclosure. The majority of sensors used in meterology ha%;e trans-
ducers whose output electrical signal is varied either by voltage or Impedance. ' These
quantities are difficult to convert to digital form and usually require a physically moving
commutator. When the sensor output Is varied by frequency, proportional to the input
variable, the reliability of the system. increaBes since no moving contacts are required.

where .4 fp Is the operating frequency deviation of the sensor. Most non-linoaritips are
of the form f = kJ x: A compensation for the non-linear characteristic of the transducer
element consists of multiplying the transducer output by kpiocewise-linear approximation
of the inverse of this non-linoarity, so as to make the output of the measuring system of
rigure I of the Enclosure directly proportional to the input variable. The block diagram of
the measuring system is shown in Figure 2 of the Enclosure. The measurement is per-
formed in two steps: determination of the number of the linearization segment and actual
measurement with correction for non-linearity. For any element K, the timing system
supplies a pulse which opens Gates 1 and 2. At the same time the inputs of two pulse
counters are supplied with pulses at frequencies frg (reference generator) and fk. When
counter I is filled, it generates a pulse which closes both gates and signals the timing
circuit that the first measuring stage it; cbmpleted. The timing circuit forms a series of
pulses required to read out from counter 2 a number wjiich corresponds to the number of

the linearization segment. 7his number is used to select proper linearization constants
(slope and Intercept) from the block of constants in accordance with the niimber of the
sensor element and the number of the linearization sector as recorded in both counters.
As a result the counter 2 output gives a digital number N which corresponds to the
magnitude of the measured variable in physical units. T~e block of constants is the most
complex part of the system. A simple realization is given using ferrite-diode elements
nnd.the current distribution principle. The signal-to-noise ratio of the block is from 50
to 200. 7lie system Is capable of handling up to 40 sensors with a measurement accuracy
Of 0. 2%. OrIg. art. has: - 7 formulas and 3 figures.

.Periodical Dok. AN SSSR,98/3, 419-422, Sep 21, 1954
Ostract The reaction of lithium addition to alpha-tri6lkylsily1naphthalin was investir
gated. It was found that the trialkylsilyl substitute increases the rate of
Li-addition to naphthalin. It was alau established that,Li attaches itself
only to the ring which has no substitute. This fact was confirmed by the
difference in the infrared spectra of these compounds. Det&iled. results of
the investigation am-presented in the table. Five USSR references (1946-

Reaction of Chloroalkylsilanechlorides with Aromatic
Compounds in Presence of Metallic Aluminum
with beta-chloroothyltri:chlorosilane was also successful. No tar
deposits were found in any of the reaction mixtures. By mixing
beta-chloroeth Itrichlorosi-lans with diphenyl oxide, the authors
obtained beta-~T~'nenoV-phenyl)-ethyltrichlorosilane (yield 22.5%).
The diphenyl oxide was silico-alkylated with beta-chloroethyl-
trichlorosilane and beta-chloroethyldichlorosilane in presence of
AlC13 and the yield of reaction products was approximately the
same as during the use of metallic Aluminum. The mount of
aluminum chloride fomed in reactions with aluminum catalysts
was very small and required no elimination.
There are 7 Slavic references.

ABSTRACT: Recently a simple method of the synthesis of hydrolyzing silicon
phosphor-organic compounds with the aid of a reaction of the
interaction of aliphatic compounds with PCI and 02 (ref. 2,3)
was suggested by the author. The American references refer short-
ly to similar papers, however, without data in the experimental
field. In present paper the author de;~cribed the interaction of
PCI and 02 with ethylsilanechlorides and tetraethylsilane. In
conLnuation of the investigation of this reaction it wasfound
that the increase of the radicals in the oriainal alkylsilane-
chloride leads to a certain increase of the yield of the chloro-
anhydrides of the substitutuents of the silicon of alkyl phosphi-
nic acids. In consequence of the interaction of the propyl-
trichlorosilane, Licthylpropyldiclilorosilane, the u- and B-
chloroethyltrichlorosilane, and the triethylvinylsilane aith

ABSTRACT: Based on earlier investigations of the same authors, in
which the silicon alkylation of aromatic compounds was
carried out with chloroalkyltrichlorosilanes and
chloroalkyldiohlorosilanas in the presence of AICI or
metallic aluminum, they investigated the same alkylation with
benzene, toluene and chlorobenzene together with dichloro-
.1391-y1silanechlorides. These reactions did not take place as
simply as the above mentioned the yields also being small
(3-48 % compared with 30-80 %);, this most probably because
of the intensive formation of resin. Besides the character
Card 1/3 of the final products of alkylation varied according to the

nature of the two components (table 1). The fact is of
interest that with a,a-,O,P- and a,p-diahl-oroethyltriGhloro-
silanes chlorobenzene reacts mainly with the two chlorine
atoms of the dich'Loroalkyltrichlarosi'Lanep giving three
times higher yields than benzene. Also toluene reacts with
greater yields, however, only with one chlorine atom, the
other being substituted by a hydrogen atom. It is known that
toluene rather easily gives its electrons to a binding with
hydrogen. In. order to investigattle the structure of the
obtained compounds their ultraviolet absorption spectra
were taken. It was shown that in the silicoa alkylation
of benzene, toluene and chlorobenzone with diahloroethyl-
trichlorosilanes one chlorine atom in the dichloroethyl
radical is substituted by hydrogen. With benzene and
chlorobenzene this reaction does not occur as main reaction,
which, however, is entirely the case with toluene. In the
silicon alkylation by means of dichloromethylsilanechlorides
no reduction reactions are observed. Ultraviolet absorption

ABSTRACT: Further to the investigations (Ref 1) into the dependence of
the reactivity of chloro alkyl silane chloride on the posi-
tion of the C-01 bond with regard to the silicon atom, the
authors investigated the reaction of the P- and y-chloro-
pro-pyl-trichloro silanes, as well as of the P- and y-chloro-
propyl-methyl-dichloro silanes, with various aromatic COMDounds
in the presence of AIC1 3 or of Al. Either silane reacted
most energetically with benzene, toluene, and chloro benzene.
This reaction takes two to three hours at 60-700 (40-60 %
derivatives yield). In order to reduce resinification in the
case of dipbenyl, diphenyl oxide, and naphthalene, aluminum
Card 1/3 was used as a catalyst, which resulted in lower yields (20-40

Reaction of y-Chloro-Propyl-Silane Chloride With Aromatic Ccmpounds in the
Priedel-Krafts Reaction
The y-chloro-propyl-trichloro- and y-chloro-propyl-methyl-di-
chloro-silanes reacted as energetically as the P-isomers,
without tiny decrease in the yields of silicon alkylation
products. Although the reactivity of the a-chloro-alkyl-silane
chloridesis much lower than that of the 0-isomers, the re-
activity of the 1-cliloro-alkyl-silane chlorides is not lower
than that of the P-chlorides. In the silicon alkylation of
benzene with y-chloro-propyl-trichloro silane, the P- and
1-isomers are thus formed in a ratio of 1:2,9; in the alkyla-
tion with 7-chloro-propyl-methyl-dichloro silane, only the
y-isomer is formed. A14the other reactions of the above-men-
tioned silanes were carried out under analogous conditions
(Table 1). The resulting complounds were methylated (Table 2).

A'BSTRACT: Only 2 patents are devoted to the synthesis and to the
investigation of the styrenes substituted in the silicium
cycle, without giving a detailed description of this synthesis
or mentioning the properties of the obtained products
(reference 6, 7). The present paper deals with the 'methods
of synthesis of the styrenes mentioned in the title above.
The general scheme of the synthesis is as follows: According
to the Grinlyar (Grignard) reaction a corresponding alcohol
is produced which is then dehydrated. Thus a silicon-
-substituted styrene is formed. This reaction was rather
successful with p-trimethylsilylphenylmagnesium-biomides,
Card 1/3 with p-triethylsilylphenylmagnesium-bromides, as well as with

alkylstyrenes
acetic aldehyde and acetone. From these the corresponding
alcohols were formed with a yield of 40 - 60%. These were
dehydrated above Al 0 at 340 - 3500C in a vacuum of 150 - 160
torr. A partial pol3mhization of the produced styrene took
place. The styrene yield was 30 - 50%. Benzyltrichloro-silane
was brominated with bromine in presence of Fe. Only one
product was formed. It concerned P-phonylethyltrichloro-
-silane. Both substances were subjected to.a spectral analysis
after previous ethylation. The spectra were similar and
contained only 2 bands (1775 and 1880 cm-1) which is
characteristic of paraisomers (reference 9). From the bromides
the corresponding alcohols were obtained by means of the
Grinlyar reaction with a yield of only 13%. From the first
of these by dehydration above Al 20 a corresponding styrene
was formed with a 50% yield. The s4rene from the second
alcohol was completely polymerized. The bromination and the
further reactions are described in details. Table 1 shows the
properties of the alcohol. The experimental results can be
seen in the same table. Properties and yields of the synthetic
styrenes are contained in table 2. There are 2 tables, and
Card 2/3 10 references, 6 of which are Soviet.

ABSTRACT: The authors measured the dipole moments of some silicon-
organic compounds according to the heterodyne method at
25 in benzene. The extrapolated polarizations were cal-
culated according to a formula of Gedestrand. For compounds
which contain silicon, the atomic polarization has to be
taken into account. The experimental results are given in a
table. A distinctive peculiarity of the silicon compounds
is the increased polarity with respect to the corresponding
carbon bonds. According to the available data, the bond
moment of Si-II may be estimated to 1D, and the bond moment
of Si-C - to 0,6D. In both of these cases, the positive end

ABXRACT: The DK-4 kit for decontaminatin weapons and military equipment
contains a gas-liquid device (see Fig. 1) and packets of SF-2 decontami-
ination powder. It uses the heat dnd kinetic energy of exhaust gases pro-
'duced by four-cycle automotive (armored- carrier) engines to decontami-
nate, using aqueous solutions of SF-2 powder and, on dry, greaseless
surfaces, vacuuming. These gases are bled off at the muffler and directed
into an ejector. Gas pressure at the nozzle of the ejectot is maintained
within 0.1-0.8 gage atmospheres by a regulator valve installed on the end

of the tail pipe. Due to the rarefaction produced-in the gas stream in the
ejector, some of the aqueous solution of SF-2 powder is sucked through
the hose into the ejector, where it is mixed with hot gases. The heated
gas-liquid mixture is then fed through the hose to a nozzle, on the end of
which is mounted a conical fitting which forms the stream s0*66'to provide
the necessary exhaust velocity.
During tfid o'pe-ration of the decontamination device about I kg of gases
and 1.5 kg of SF-2 solution are expended per minute. The temperature of
the stream leaving the nozzle is 55-65"C, and the exhaust velocity is
150-200 m/sec. When using the vacuuming method of decontamination,
the vacuum produced in the ejector by the gas flow sucks up dust swept
from the surface by a brush into the nozzle, through the hose, and into
the ejector. It is carried through a pipe to a container filled with a small
quantity of liquid or into a specially prepared hole.
The vehicle's exhaust system must be adapted before the gas-liquid
device can be used. On the muffler inlet pipe is mounted a gas take-off,
and at the end of the tail pipe is a nipple to which is connected an end c~Lp

with a valve. In addition, the careful sealing of all joints in the exhaust
system is carried out, since there would otherwise not be sufficient gas
pressure at the ejector nozzle with the engine operating at moderate speeds.
Since it does not use a mechanical drive, and there is therefore no in-
ternal friction, the gas-liquid device inc 'luded in the DK-4 kit features high..
reliability and Sim Ii it of operation. Orig. arts has: 3 figures.

ABSTRACT: The article deals with research on electrically welded
(resistance weldinl m thod) tubes manufactured by the
plant imeni Lenin tute dimensions - 152 x 5 and
114 x 5 mm) and thi Moscow tube plant (tube diameters:
22, 38-and 51 mm).' The 152 x 5 mm tubes were made of
St.2 steel, the n4 x 5 mm, of St. 3 steel and those with
22, 38 and 51 mm 'diameters of steel "marki 15". The '
tubes have not been heat treated in the factory. Testing
of the macrostruc7ture of the welded seams have revealed
no non-fusion. Tensil strength tests were run on 700 Mm-
long tube samples (some with a transverse welding seam
in the middl6) which were subJected to pressure high

failures along the longitudinal seams. Ruptures
appeared-at a distance of 27-35 mm from the longitudinal
seam. Table 1 shows-the results of tests performed on
114 x 5 and 152 x 5 mm tubes at room temperature.
Table 2 shows the tensil strength and relative elonga-
tion of the tubes and the tensil strength of the welded
joints at seven different temperatures, ranging from
20 to 4500C. Cor 'r-osion tests were conducted on welded
tube samples, 22, 28 and 51 mm in diameter and 40 mm
in length. Tube-samples of larger diameter were
30 x 40 mm. They were cut out at the welding seam and
at 90 and 1800 slig'les to the welding seam. The*samples
were subjected to 1% aqueous hydrochloric acid at 200C
for 1100 hours and W 1% aqueous hydrochloric acid
saturated with hydrogen sulfide, at 200C for 100 hours.
Test results showed (Table 3 and 4) that In all tube a

tubes 152 x 5 mm-_with welding sewn was 1.7 - 2.6 greater
than'the corresponding loss of weight in samples of the
basic metal. Tubes with thin walls were eaten through
along the welding seam (Fig. 2a). It was assumed that
uneven corrosion stability of the metal along the
perimeter of them tube was due to structural heterogeneity
of the metal and"that by equalizing the structure by
heat treatment'its chemical stability would be improved.
To test the valicTity of this askumption, the tube samples
were heat treatea"'at 690-7100C and at 900-9200C and Bub-
sequently Vested' with the above mentioned solutions for
corrosion stability. Test results (Tables 3 and 4) showed
that heat treatment increased considerably the corrosion
stability of the welding seam zone. The character of the
corrosion was more uniform without visible impairment
of the butt weld:-(Fig. 2b). A wide applicatlon of these
tubes depbnds also on how readily they can be bent.
Bendine experiments with tubes, 114 x 5 mm and 152 x5 mm,
lj-i_.~ m long and filled with sand, were conducted at
the Moscow refinery. The bending curve was 4-5 times the
diameter of the tube. The longitudinal seam was located

flexed tube. Hydraulic tests revealed no failures in
the basic metal or in the seams. Flared, heat treated
tubes (25 x 2.5 and 33 X 1.5 MM) were also tested
(at 25 atmospheres) at the Moscow refinery. Tests
showed no craclis In the welding seam. The author con-
cludes that: 1) electrically-welded tubes (resistance
method) are as strong as seamless tubes and can be
substituted for them; 2) electrically welded tubes, not
heat treated, have low corrosion stability which can be
greatly improved 'by heat treatment'; 3) in the petroleum
industry electrically welded tubes can be used to trans-
port petroleum a~fid can serve in refineries for transfer

detail and the following conclusions are arrived at:
1. The intensity of austenite transformation in the
steels OX18H9, 1X18H9 and 2X18H9 during holding 8ver
long periods in the temperature range 500 to 0900 C and
also the character of the separatiniL out phases depends
on the temperature, the holding time and the carbon
content in the steel.
2. In steels with low carbon contents,of the order of
0.07% (OX18H9),the transformation takes place as a
result of formation of the a-phase and of carbides and
these processes are completed only at the rrain boundaries.
3. In steels with a comparatively high carbon content,
of the order of 0.18% (Mffiq), the transformations take
place fundamentally as a result of separa8ion of the
carbides. Holding for 3500 hours a8 700 C and holding
for shorter durations at 800 and 0,00 C brings about
transformations throughout the entire grain, which is
not the case for steel with lower carbon contents.
4. From the point of view of the character of the
transformationsl the steel lXl8Hq occupies an intermediate
Card 3/5 position between the steels OX18H9 and 2X18H9 but it is
nearer in its behaviour to OX18H9,steel.

12Q-4-4/12
Influence of long duration heating on the structure and the
properties of Type 18-8 steels.
5-In addition to austenite decomposition, a diffusion of
chromium from the more enriched parts of the grain into
the impoverished parts and a partial transformation of
the (x-phase into the y-phase seems to take place in
18-8 type steels. Therefore, on increasing the holding
time or the temperature, the magnetic saturation drops.
With increasing temperature and holdinG time carbide
coagulations are observed.
6. The Cr-Ni-Mn austenite of the steel X13H41'9 is less
stable than the Cr-Ni austenite of 8he steel 18-8; the
transformations taking place at 600 C lead to a sharp
decrease of the impact strength of the steel X13H4r 9.
7. The steels IX18H9T and X18H116 become transformed
as a result of long duration holding at 500 to 800 C;
the nature of these transformations differs from that
of transformations in steels without Ti or Nb.
8. The steel lX18HqT containsoin its initial state and
after annealing at 500 to 700 C a certain amount of
ferrite in addition to the carbides (and in some cases
also a a-phase), The austenite of the steel X18H115

transformed into ferrite during heating.
9. The structural transformations in type 18-8 steel
lead to a strong drop of the impact strength and to a
certain reduction of the plastic properties during
static fracture. The decrease in impact-, strength and
ductility of steels containing Ti and Nb is more
pronounced than in similar steelsnot containing carbide
forming admixtures.

ABSTRACT: The article deals with intercrystalline corrosion at joints,
welded by electrodes "ZIO - 3" of the type 11EAlB11 on steel
'IlKhl8N9T" (used for vessels and pipes in the petroleum proces-
sing and other branches of industry). The following conclu-
sions were made. 1) The welds do not develop intercrystalline
corrosion after welding, hardening and heating for 2 hours
at 6500C. 2) Long heating at 500-6000 makes both the welds
and the base metal prone to intercrystalline corrosion, and
this tendency increases with an increased duration of heating
from 100 to 5,000 hre. With heating at 65001 corrosion-
proneness becomes less, and finally disappears as the dura-
tion of heating increases, 3) Welds subjected to stabilizing-

PERIODICALt Khimicheskoye mashinostroyeniye, 1960, No. 5, PP. 34 - 37
T M t Test results concerning the influence of long-time heating on the
intererystalline corrosion tendency of cast steals are given. Tested were
Kh18N9T-l steels containing titanium and carbon at a ratio varying from 4-5 to
13 [Ti : (C - 0.03)] and 18-12 steels with a higher content of nickel. Samples
were subjected to two types of thermal processing, i.e., hardening at 1,050 -
1,1000C in water and hardening followed by 3-h stabilization annealing at 850 -
8700C. Preliminary tests revealed that the conventional method of bending 4-mm
cast steel samples is unsatisfactory, making it difficult to determine which
fractures were caused by intercrystalline corrosion and which by the reduced
plasticity of the metal. Therefore, only samples of 1-mm thickness were used in
final tests, a brief description of which is given. Classification of samples
as to their tendency to Intercrystalline corrosion was based on losses of metal
sounding, bending tests and changes in electric resistance. Results of tests on

Tests carried out in the Institut svarki Akademii nauk USSR (Welding Institute
of the Academy of Sciences of the UkrSSR) showed that addition of ferrite forming
fillers (Si. V, Al) resulting in an austenite-ferrite structure of joint metal,
rapidly increase the ffimmunity" of welded joints, according to B.I. Medovan (Ref.
4). Present tests proved the contrary, i.e., that even a content of 20% ferrite
and high relative contents of titanium and carbon do not eliminate the tendency
toward intercrystalline corrosion of heated 18-BT steel. It was proved that the
stabilization annealing of Khl8NqT steel with Ti : (c - m3) > 6.6 considerably
increases its intercrystalline corrosion resistance at 500 - 6000c, though not
rendering it oomplotely immune as in the case of rolled steel (Ref. 5. Kh-I-
Cheskis, S.I. Vollfson and Yu.S. Medvedev). Kh18NqT-1 steel used at increased
temperatures in mediums causing intercrystalline corrosion should be subjected
to austenitic hardening and stabilization annealing at which the relation of Ti:
t (C - 0.03) should not be lower than 6.6 - 70. There are 2 figures, 2 tables
and 5 references: 1 German, 1 Polish and 3 Soviet.
