ABSTRACT: A comprehensive investigation of the performance of an 1150-
millimeter blooming mill showed that the factual amount of widening
that occurs in the rolling of blooms and slabs is ~ significantly
greater than the customary calculation5 would indicate. This error
in computation of the widening led to a faulty distribution of:the~
reduction during vach of the rolling passes.* Measuring the, pressure
of the metal on tKe roll s and thecurrent. in'the armature of the
motor revealed the availability of reserve power, which could be
used to in-crease the reduction in a given pass in the bloomi,ng mill.
The greatest specific pressure in the rolling of mild and medium-
carbon stet-l~~ - -is exhibited by killed steel.: MZ subjected to cold

TITLEj Coordination of Rolling Mill Operations
PERIODICAL: Stall, 1961, No. 2, PP. 135-139
TEXT: It was found from photochronometrical recordings that'the output of
the two-high reversing bloomingimill (1,150) and the!tube rolling Mill on-
sisting of two-high reversing blooming (goo) and three continuous stands
(75A of the new rolling workshop at the zavod im.Dzherzhi,n_skiy (Plant im,
Dzherzhinskiy) fell short of expectations. Lack of coordination in operat-
ing the various machines caused breakdowns amounting to 56% of the working
time. The entire operation was graphically plotted with the aid of.photo-
graphy and in this way an indication of the metal flow and of the load of
the machines in time was obtained (Fig.2). The graph showed that the output
of the mill could be increased by supplying various types:of billets:and

order to ensure the uniform loading of all machines of the'unit, the, mathe-

mill 900 as "transit" product, while during the remaining time.tubes;can be
rolled in a quantity corresponding to the capacity of,the;heating furnaces,
as well as slabs for the general workshops. The relation.b.etween the vari-
ous metal flows was determined from the metal-consumption:coefficient for
the blooming mill and its average output.~ It was found that the efficiency
ratio of the mills did not tally with the ratio of their~operational:.time,
The productivity of mill 1500 on which two ingots can be ro lled at a time,
was higher than that of mill 900, However, the low,output,of pit fuIrnaces
creates the bottleneck in the production process. Their capacity can be
raised by increasing the temperature of ingots.during feeding, by reducing

the time of cold feeding, eliminating idle time and not retain metal in them
any longer than necessary, moreover,-by inte nsifying~~the hPating.of ingots
and increasing the number of travelling cranes. By.drawing:up a detailed
operation-schedule for the mills in question, according to the investiga--
tions and calculations carried out I the mills are novr utilized more.fully
and the savings effected by the 1500'and tube rolling mills only with r'e-
gard to permanent costs - amount to about 500,000 rubles per annum. There
are 2 figures and 3 tables.

TITLE; Therj,~ial alkylation of methylcyclohexane with olefins
under pressure
PERIODICAL.-Neftelchimiya, v.-1, no.-5, 1-961, 613-618
TEXT: The authors reported.recently that alkyl,ation.of cyclo-
hexane and cyclopentane can be achieved thermally (350 to 450"C)
under pressure (50 to 200 atm). Further work on alk ylation of
methylcyclohexane with olefins was carried'out.to elucidate Vie
influence of side chains on the direction and ease wi-th which the,
reaction proceeds. The reaction was carried out in.a reactor,
filled with quartz rings. Molar ratios of methylcyclohexane to
ethylene were from 2.5 to 3.6 and for propylenel~.4 to 3.2. The
space velocity varied between 0.81 and 0.99 litre/ho,u'r for
ethylene and 0.52 to 1.43 litre/hour for propylene. 'All
experiments with propylene were carried out*at 4500C, whereasfor~
ethylene the temperatures varied from 350 to 450.OC. . Resultsishow
that the main product of the reaction of methylcyclohexa.ne with
Card 1/3

Thermal alkylation E075/E484
ethylene is a mixture of methylethylcyclohexanes, the proportions
of various isomers differing from their equilibrlium concentrations.
With propylene the reaction proceeds with more~difficulty and the
yield of alkylate is lower than that obtained f,or ethylene
(155% of propylene taken and 316% of ethylene respectlvely).~
Comparison with previous work (Ref.7: N.M.Nazarova,~L.Kh.Freydlin.
Dokl. AN SSSR, 137~ 1961, 1125) shows that the.'alkylation of methyl-
cyclohexane proceeds more easily than that of unsubstituted cyclo-
hexane:. The reaction begins at a lower temperature (3500C):and
pressure (50 atm). The expected formation during the reaction:of
1--methyl,-l-ethylcyclohexane was not observed, which is explained
by thermal instability of hydrocarbons with quaternary carbon atoms,
It is postulated that 1,3 and 1,4-isomers are forme :d1b y an internal
rearrangement of 1,1-isomer or via an intermediate.stage of
migration of free valency of methylcyclohexyl radical from
position 1.1,to positions 1,3 and 1.4. Acknowledgments are,
expressed to A.L.Liberman and T,V.Vasina for supplying the
niethylethylcyclohexane samples. Yu.G.Mamedallyevl Aladdin Kuliyev

TITLE On the Stability of a Cylindrical Gaseous Conductor in a
Magnetic Field.
PERIODICAL Atomnaja Energija,.Li fasc.5, 36-41 (1956)~~
Issued: 1 / 1957
The present work, which,.like Yi.KRUSKA1 and M.SCHWARZSCHILD, Proc~Roy.Soc-
A 233, 348 (1954), employs the method of small oscillations, and which bases
its assumptions on ideal conductivity, investigates stability against longi-
tudinal disturbances in the case of the presence of a "longitudinal" field
(i.e. in the case of the existence of components of the magnetic field.which
are directioned along the cylinders.
The system of equations upon which this problem is based consists of the
equations of magnetic hydrodynamics for an ideally conductive medium:
dQ/dt + Q div 'V-o,30/at = curl P-const Q?* Q dv/dt- - p + (1/c
VH
In the case of equilibrium it applies that v 0, a/at~= 0; the cylinder is
then homogeneous with respect to axis and~aziauth (a/az a/a 0), and the
components IH0an Ho are different from zero Within the cylinder it is

Nexti the equations resulting for these corrections are.written down. The
corrections to the field outside the cylinder are determined from the
epations H V 'p, A T - 0. Because of the ideal conductivity the.magnetic
lines of force are withdrawn from the substance parallel.to the surface.
Therefore the normal component of the field is-equal to.zero,,and the e.x-,
terior field does not dependon the interior field. For.its'Value on the sur-
-face of the exciting cylinder explicit expressions are given. The solution ob-
tained f?r the corrections is correct in the case of a fully determined- eigen-

from the equation of motion). In the present case this is reduced to the con-

Next, this condition is to be transformed. Besides a positive spectrum of
2
solutions,W >V (which corresponds to the sound- and ALFVEN,waves of the g 8
in the excited cylinder), this equation also has a branch of'e,igen valuescom(k)',
which has a negative sign within a certain domain. Inthe case of a van-
ishing longitudinal field this branch is about m-O and m=1 quite in the nega-
tive domain, but if a longitudinal field exists, this.branch:passes into the
positive domain in the case of great k. In conclusion some special cases are in-
vestigated.

The neutrons were observed.at the,2. and 34

By means of scintillation counters it was proved
that the neutrons from the,domains near the
discharge axis (of a diameter of not more than
2 cm) are formed simultaneo'usly.on the entire
length of the tube.
A number of theoretical lectures dealt with the
conditions of the non-stability,,of magnetically-

In the chapters 1-3 the following cases are dealt withs
1) Gravitating current-carrying ring,
2) Current carrying ring which is situated in a gas atmosphere,the
pressure of which is greater than the pressure within the ring
3) Current-carrying ring situated in an homogenous magnetic field.
Case 2 is of special interest because this system can probably be

scribed as a magnetic vortex ring) with identical distribution
of the magnetic field and the velocity corresponds, for in-
stance, to a ring-shaped current in a magnetic field and to a
circularely-shaped vortex. At D(_ a othe magnetical vortex

in equilibrium is at rest, and at DG aD it is transformed

ABSTRACT: This paper derives the general formulae for.an:electro-
magnetic field in a semi-infinite homogeneous'anisotropic.
medium with spatial dispersion, it is a generalization
of the second part of the well-known paper of Landau (Ref: 1).
The first part of this paper derives the general formulae~
which describe the permeation of longitudinal and transverse;
ormulaef
fields through the abole mentioned medium;lthese f
.
may be deduced from the corresponding bou~darylconditions.
The author investigates a motochromatic field with a time
dependence of the type e-iC* . The field penetrates (coming
from the vacuum) into a medium which fills up the semi-
space z >O. The SDatial dispersion implies a functional-4,

of the electrons) a local connection between D:and
is obtained. In a semi-infinite medium the dependence
of 1, 11is connected with the properties of the separating
surface. The charges are'assumed to be reflected from the,
boundary like by a mirror. In the general.field the
electro-magnetic field may be described by an integro-,:.
L'Afferential equation. Subsequently the author,reports
on the boundary conditions. The above mentioned integro-
differential equation may~.be solved by expanding al:
quantities into plane wave's. The author then calculates',
the permeation of longitudinal and transverse fields. The
second part of this paper calculates the propa:gation of a
transverse electromagnetic field into a plasma. along the
magnetic field. For a given frequencyw t 'he transverse
electromagnetic field in a medium Twith spatial dispersion,,

real case, the electromagnetic field has to be calculated
with taking into account the boundary:conditions. In a
plasma, the field may be represented in the form of 2
parts: The phase velocity of one part..Of the~field depends
on the coordinate z and the other part of the field is an
ordinary wave. The author thanks M.A.Leontovich, Member,
Academy of Science3, USSR, who proposed the problem and
gave sugGestions for this paper. There are~3 figures and
12 references, 12 of which are Soviet.'

TEXT; The authors of the present paper study the instability of a plasma
with a non-Maxwellian velocity distribution of iona (or elealtrons). The
instability is assumed to have two causes: 1) the existence. of a "beam
2) longitudinal or transverse Iltempe raturell anisotropy:*ith,resDect to them
static magnetic field. The latter case is studied in this paper. Preceding
papers (Refs. I and 2) have shown that a convective instability (Re(&))~O)
may occur in "drift" approximation with a-sufficiently~strong.lanisotropy
~of.the ion (or electron) temperature-The "drift" apprdximation employed
in these papers is, however, only applicable if the Larmor radius of ail
particles is very small cc ared to the perturbation wavelength, i.e.,:
MP
if the Larmor frequency is very high compared to the vibration frequency.
