A.BSTIRACT i The above-mentioned other has hitherto only been used in
surgical practice. Only after a thorough investigation of the
divinyl ethers it is possible to evaluate the possibility of
their use also in other domains. The authors occupied them-
selves with the investigation of the properties of this ether
and founds According to its structure (CH2 - CHOCH - CHf) it
belongs to the simplest ethers. Under the influence of orric
chloride and stannic chloride it cannot be polymerized. In this
paper it is shown that divinyl ether quantitatively splits
according to the following schemes

Earlier (Rafe 1-3) the authors had inve3tivated the ¬-
nlous affiliation of hydrogen culfide to the vinyl others
and they found that dinitrile of the azoiaobutyric aoiC
was the most efficient of all catalysts used. In this paper
the affiliation reaction of H2S to the divinyl ether is
carrie4 out in their presence. Some other affiliation
reactions to this ether are deacribed as well; Halogenation and
hydrohalogenation (nef 4), affiliation of CCI 4 (Ref 5)-
un zhis problem there are only affiliations of S to the
diallyl ether and ito homologs in the pr 5 butyl

At low temperatures, increased pressure and under ultra-
violet irTttliation viscous products of aone practical
import,%nce (scheme 1) were obtained scoording to data
Mentioned itt patents (Refs 7,0). The authors carried out
the reaction of H S with divinyl ether in the presence
of the d1nitrile 9f asoiaobutyric acid. This reaction took
place stepwise tinder the fortlation of a mixture of chain-
like dithiols of different composition (Scheme 2-a,biv).
The formAtion of conpound (111) can be explained by scheme
3-1,b. The compounds (I-III) were obtained with a great
excess of H2S (Table 1). The fornation of cyclic and poly-
neric produati was not observed. Vnrying the conditions
of the Initial products sulfide dithiols could be obtained
in laree quantities (11, 111). H S was used in liquid state.
Thus, the dithiol and nulfide diihiol were synthesized, and
it va3 demonntratei that these conpounds have a still greater

thiole h@ve. Sam* dithio- and trithioethere (V) were
synthesized. There are 2 tnble3 and 14 references, 9 of

TITLE: Nonstationary ljeatexc4 e under laminar flow of a fluid in a tube,
SOURGE: AN SSSR, Institut dviiZateley, Trudy, no. 6, 1962, 51-60
TOPIC TAGS: heat exchange, heat transfer, stationary, nonstationary, laminaro
flow
ABSTRAGT: The paper employs the relative simplicity of laminar flow in a tube,
with its molecular conductivity and parabolic velocity profile, to simplify the
equations of the nonstationary process and to analyze them theoretically. It is
a9sumed that a viscous, incompressible, fluid is engaged in a stezdy-state
laminar flow within a semi-finite circular tube and that, following an initial
period in which no temperature differences obtain, suddenly the tubular walls
attain a temperature that is at variance with the temperature of the fluid, where.
upon a nonstationary temperature field arises within the fluid. Assuming that a
heat flux adduced to the wall maintains the wall at its now temperature, the pro-
cc 9 s will become stationary after the passing of a sufficiently long time. The
author seeks to obtain the distribution of the temperature of the fluid in an axial

and radial direction, both foethe transition period (nonstationary process) and for.
the terminal case (stationary regime). Basic stipulations: (1) Temperature-
independen! physical properties of the liquid; (2) the fluid temperature in the
initial section remains constant throughout the process; (3) the wall temperature
at any given time is uniform; (4) the viscous diffusion of energy is negligible; (5)
the the rMal diffusion in an axial direction is negligibly small in comparison with
the diffusion in radial direction; the axial temperature conductivity, therefore, is
d%sregarded. The problem of the stationary state (disregarding the convective
term) is first solved; the solution is expressed in terms of a solution of the Sturm-
Liouville problem and is found to solve the stationary problem fully. The nonsta.
tionary problem is then resolved. and it is found, as expected, that for large
values of the tirne t the solution obtained assumes the form of the steady-state
solution. The stdf@-by-step procedure of the calculation of the temperature fieldi

TEXTi The use of a heterogeneous nagn*tio field in sees spectrometry
has some advantages. The gas content in samples of bismuth, gold,
germanium, zirconius, lanthanum, and various types of copper was deter-
mined here. The experiments were carried out in a special glass
apparatus (Fig. 2), and a special device (Fig. 1) was used for the
introduction of the gages. The gas current wa;)r:gulatod with a bimets.1
capillary (of 91A -69-(RU-69), or M-3C (SI-3 teel). The analysis of
the gases separated from the metals was carried out with a glass mass

The optimum output is 600 kg/hr. Tests show this output to be 52 times as
great as that of an analogous ball mill and 3.5 times as great as that of a hib-
ratory crusher fed with 3-0 mm Krivoy Rog ore. Power consumption is f@ss
by 29-4716 and 69-770%, respectively. The use of grinding cylinders instead
of balls increases grinding intensity by 50% while raising power consumption

They are welded on a stand with longitudinal seams. The middle

from the inside. The bottom of the WL had the shape of a spherical segment with
flanges. 26 - 30 mm 2OK steel plate was used for the bottom. After welding the
WL were tempered in a pit furnace. The tempering comprised heating to 600 -
7000C and soaking for 3 - 5 hours with subsequent complete cooling in the furnace.
Malla are adduced on the welding procedures for the inner and outer seams, the
macrostructure, and the mechanical properties of the scam metal. Measurements

ture under full load (with the ladle full of met-al) established that in spots of the
greatest loads the tensile stresses attained 400 - 250 kg/cm2. The author notes
that in individual members of the WL structure the stresses incr6ase appreciably
(by 10 - 200/6) at the moment of the lifting of the ladle hv the crane, which fact is
explained by the dynamic acceleration of the ladle during hoisting. Investigation
of the WL showed that they possess sufficient strength.

mill is described and illustrated. Main points:
replacement of the top roll positioning and balanciag
arrangements and the drive of vertical rolls by a more
rational nechanian operated by a 50 aft, hydraulic system.
As a result of this modernisation the output of the mill
1ncreased approximateLy by 25%. There are 8 figures.

ABSTRAM .-A method to offered for calculating the approximate ex-
pected life ;)f - cable --insulation and of the relative
elongation or rubber in the aging process. The aging
teats were conducted at 800 for 200 days, and at 900
for 100 dayso according to OOST 271-411 the samples
were prepared according to GOST 269-53; the mechanical
characteristics were determined according to GOST 270-
53, and the electric breakdown, according to GOST 2o68-54
and GOST 6433-52. The aging of rubber Is a first or-
der reaction which can be expressed by equationt
