TITLE: Study of the effect of stresses arising during the swelling of the gel on the
quality of meteorological radiosonde enylopes
SOURCE: Kauchuk- i rezina, no. 11, 1965, 34-35
TOPIC TAGS: radiosonde, gel, rubber, mechanical stress
ABSTRACT: In the manufacture of radiosonde envelopes, an important parameter is
the magnitude o:E the stress arising in the course of swelling of the gel. The ef-
fect of this pa,cameter on the tensile properties of type-150 envelopes was studLed.
The stress was 'varied by changing the duration of syneresis from 10 min to 7 hr,
which caused changes in stress ranging from 5 to 11 kg/cm2. In order to characterize
the tensile properties of envelopes of the same size but prepared in different
ways, use was made of the so-called quality factor (ratio of ultimate elongation of
envelope to ultimate elongation of sample). To determine this factor on an instru-
ment for two-dimensional deformation, the ultimate elongations of samples cut out
of envelopes with various stresses in the gel were measured. The ultimate elonga-
tions of these samples were all found to be equal on swelling and amounted to

~- - 8.8. On the basis of tests of samples and envelopes, the dependence of the
quality factor of radiosonde envelopes was platted versus the stress in the gel
during swelling (see Fig. 1).

In the manufacture of radiosonde
envelopes, wi important parameter
is the magnitude of the stres-s-i-a-r-i-sing- in the course of swelling of the

100% 0~-phase to be used for magnetic determinaticn of .he amoum'.. %f austenite
retained in 18 - 8 steels. The authors review the existing methods, aE described
in various papers (Refs. I through 11), and conclude that the problem of obl~ainl.ng
a proper standard of 18 - 8 steel for magneti-- tests has not been definitely solved.
To obtain this standard, experiments were conducted wl,.h specimens made of four
18 - 8 types steel having chemical compositJon as listed In T-able 1. Sperimens,
made of a supersaturated wire rod, 7 mm in diameter, were ~-,retched in liquid nitrc-

TEXT: Experiments were carried out with killed "M16C11 (M16S) low-carbon
open-hearth steel and "CT.3" (St-3). M165 steel was melted in basic 200-
ton furnaces with magnesite-chromite vault in the scrap-ore process and
aluminum was added into the ladle after the obligatory deoxidation in the
furnace. Addition of 45~'--ferrosilicon (3-5-5 kg/ton), aluminum (1 kg/ton)
and ferrotitanium (0-7-0.8 kg/ton, with 26% Ti content) was tried.
Rectangular 1,550 and 1,840 mm high ingot molds were filled by bottom
pouring. Deoxidation of M16S steel by ferrotitanium being obligatory,
excessive oxidaticn of titanium was prevented by adding part of aluminum
before ferrotitanium into ladle and the rest in even portions into the
pourin6 gate during pouring. St.3 steel was poured without ferrotitanium

TITL-Ei Behavior of Sulfur in Open-Haarth Furnaces Fired by Natural Gas
WLth Self-Cgrburization
P31HODICU: Stall, 1960, No. 12, PP-1075-1078
T."!,XT -. When open-hearth furnaces are fired by natural gas with self-
carburization instead of a coke-oven mixture, the composition of the charge,
the amount of additions and mainly the behavior of sulfur in the finished metal
and during melting as well, will be different. The Zaporozhstall Plant, in
cooperation with the institutes of gas utilization and iron metallurgy of the
AN UkrSSR designed schemes to change the firing system of this plant from coke-
oven mixture to self-carburizing natural gas (N.N. Dobrokhotov~ I.I. Kobezaj
K.A. Greben', L.D. Yupkog Y.T. Garchenko, and A.L. Turubiner, Stall, 1960, No.
1) and relevant tests were carried out to investigate the changes in the techno-
logy resulting from this new system, and especially the behavior of sulfur
during melting and in the finished metal, described in the present article. The
experiments covered about 200 meltings according to the conventional technology
while some of them (Group I) were carried out in a natural gas-fired furnace

and others (Group II) with the usual coke-oven mixture firing. The changes in
sulfur. content in various stages of the process and ia the finished metal were
plotted in frequency graphs. During the tests low carbon rimming and killed
steels (mainly 08Krr - 08kp, UB - VGV,DBfB=OVGV,CT.3rt7 =St-38p, 1OKn = 10kp, lKrr
=1kp, 2M=2kp, 08IM?K =08kpzh, 08W.08yu, CT.3CYA =St.3sud, C-r. 4c" =St.4sp etc) were
producedg partly by bottom casting, partly by top casting. In the natural gas-
firing process the air was enriched by oxygen to about the same degree as when
firing with coke-oven mixture. The S-content in the finished metall was found
to have decreased,on an average, in the Group I tests to as little as 0,0208%,
as compared with the 0.02714o S-content of the metalt. of Group II. The graphs
also show that the main part of Group I melts Oeic) contains not more than
0.016-0.024 S, whereas the main part of Group II melts contains 0.025-0.030%.
In other words: the degree of desulfuration in Group I-metals is 43.8%, whereas
the percentage for Group II is 23.4p i.e.,20~1. lower. The decrease in S-content
in the finished metal, in Group I tests, is not accompanied by structural changes
in the metal. Another remarkable feature of the change in S-content of the

metal in the nevi firing system is that the-removal of sulfur is more uniform,
it takes place during 1"he entire melting Deriod. Of the total amount of S
(0.0162~'fo) removed froa the metal, 0.0060,~46_is sepa:rated- during the first half
of the melting proc~-~ss and O.OlOep during its second half, in the Group I melts.,
,ihen firing with cc -.e-oven mixture v however, 0.0082,'0' 3 is removed during melt-
ing and from this .nount only 0.0010% during the first half of the process and
0 .007 25 during the second. This uniform S-removal from the metal during the
Group I meltings is explained by the favorable constant atmosphere of the
furnace due to natural gas firing. 71ith regard to tempe-rature it was found
that on account of tbe metal fluidizing more inten31vely before oxidation its
temDeratuxe in Group I is about 10-150C lower than in Group II. With regard
to melting time it was established that when firing with self-carburizing
natural gas and increasing specific oxygen consumption by 7-8,~af, the melting
time could be shortened by about 1 hour COMDared with coke-oven mixture firing.
The Group I meltings viere carried out at the end of the furnace camDaign, i.e.,
under less favorable conditions than those of Group II. Thus, the better

The application of the method of C111YC444
where ~c indicates the mentioned wave domains, The representation (9)
then serves as base for the proof of the particular assertions of
theorem 1,
Theorem 2 says that under the suppositions ot' theorem I the obtained
solution is unique.

Title An "IR-211 (H P-2) type instrument for testing discharge.5
Periodical Vest..svyazi 8, 8-9, Aug 1954
Abstract; The "IR-211, instrument used for. testing dischargers of the RA(PA) and RB (P 5
types, carbon-type and.other type dischargers installed on cormiunication lines,
is described. The'difference between the "1R-211 testing instruments and, the
earlier, " IR-49" instrument. is outlined and the relative advantages. of. the form-
er (IR-2) type explained.. The method of assembly and operation o f the instru-
ment is demonstrated and an'operation chart is included. Diagrams; illustra-
.tion; table.
