Better results were obtained in the works mentioned last, On the basis of
the experiments conducted at various works the main parameters for the
conditions of heat treatment could be determined. The studies of mechanical
properties of steel subjected to heat treatment (Table) show that on
tempering carbonsteel plates of type St. 3 sufficient homogeneity is
obtained, Thicker plates have more uniform mechanical properties with
good plastic properties being obtained at high strength. In spite of the
good results obtained heat treatment is still imperfect since the values
of the relative increase in length are frequently below the standard

sary. Cold brittleness and mechanical ag2.ng of carbon steel whi-ch were
observed in an experimental series are lower than in 'low-alloy steels. In
the case of thin cuts the St., 3 steel. subjected to hoat trentmotit may
replace low-alloy steels with a yield point of 30 kp/mM2. The use of
carbonsteel subjected to heat treatment proved to be favorable also from
the economic point of view. The experience g~?Aned at the Alchevskiy works
in the heat treatment of steel boiler plates showed that the strength
of carbon steel subjected to heat treatment attains the strength of some V
hot-rolled low-alloy steels, On the basis of a large number of experimental
data collected in the works the COST 9458-60 standards for the mechanical

ABSTIUCT: Tfie authors discuss the variations In thickness of two-layer steel
caused by a.combination of variations and nonunifornities in the thickness
:of the individual slabs which make up the pack. These variations may reach
�20% of the nominal value in individual cases. Variations in the thickness
was determined for M s produced sheets with a cladding layer 6f KhANIOT,
,"Khl7N13142T and OW34tsteel. The variations in thickness and deviations from
~nominal. -vialue w-e-r-e--s-tudied during rolling of bimetal shoot from packs weighing
less than 5 tons (small packs) and from packs weighing 10-12 tons (large
.packs). Shoot rolled from large packs shows less variation in thickness than
.that rolled from small packets. This is because the large slabs wore hot when
they were fed into the continuous furnaces and were therefore heated more
~uniformly. However, completely uniform heating was impossible even in threes
zone continuous furnaces. The following furnace condi#qps are recommended

'for reducing variations in the thickness of_plates rolled on the 2800 mill.
'Temperature of upper and lower sections in the joining zone should be identicalt
.1300-1310OC; temperature of the soaking zone should be 1260-12700C. Total
heating time should be divided into 40~ for preheat, 30% for joining and 30%
.for soaking._
!Experiments showed that planin.- the slabs on both sides reduced variations in
~thickness up to approximately 20%. The lubricating interlayer has a low
thermal conductivity and impedes heat exchange between the upper and lower
.parts of the packet during heating which prevents temperature equalization.
This causes variations in the thickness of the finished shoot. It was found
'that the absolute variation in thickness increases with the thickness of the
sheets. The relative variations in thickness are approximately the same for
'sheets of an thicknesses with the exception of 16 mm sheets for which variations.:
:are somewhat lower. In 80% of the cases, deviations from the nominal thickness
;vary within limits from -10 to +12%. The following recommendations are given
for reducin& deviations from the nominal thickness using existing equipment:
reducing variations in the thickness of in'itial slabs to +2 mm by eliminating
.bending or by planing on both sides; increasing thickness7of the upper slab in
the pack by 7% as compared with the lower slab; heating the packets in continuous
furnaces with egual temperatures for the upper and lower sections in the joining
lZone, a temperat=e of 126VC in the soaking.2one and holding in this zone for-
30~ of the total heating time. Taking part in the work of the article were TWIMM

19G3 at the Kommunar plant, the authors specify the difficulties encountered In the previous
cast-cladding process and Indicate that higher technological efficiency and production on
a much larger scale can be achieved with the new process without affecting the high quality
.of the product. To produce two-layer sheets, symmetrical four-layer packs whose size-
is prescribed by nomogramajare assembled from the basic steel plates a, Clifidding plates b,
and interlayers c, as shown in the Enclosure. The equations from wWch specifications of
the pack components are found, the necessary -nomograms and the details of the process

proper upper-to lower plate thickness ratio. This ratio (optimally about 1. 08), designated
the coefficient of equitbickness, is introduced into the calculations to offset non6niform
metal expansion due to a temperature gradient across the pack during heat treatment. To
reduce this effect, the temperature In the upper, lower and tempering section of the furnace

T=.- The roll separating force of the metal and the loading of the main

T W i The authors studied the power conditions for rolling at the thick-
sheot mill 2800 of the Plant imeni Voroshilov. The mill is designed for rolling
sheets with thickness 6-- 50 mm, width 2,500 - 2,600 mm. It consists of a stand
with vertical rolls, a roughing two-high stand with working rolls 1,150 mm dia,
a universal finishing four-high stand 800/1400. The stands are arranged in a
sequence. The roll separating force of the metal,in the roughing and the finish-
ing stands yas measured by means of force meters with wire tensometers. The
force meters were welded to the pedestals of the working stands on the side of
drive. The pulses from the tensometers were recorded by a magnetoelectric os-
cillograph HOB -14 (POB-14). A callculation of the forces from the torque was

The roll separating force of... A06Q/AIOI
carried out to verify the values determined by the force meters. The mean pres-
sures were calculated from the total forces obtained experimentally. Simultane-
ously with the measurement of the forces, the operation of the main drive motors
was oscillographed. The osaillograms recorded the current, voltage, and the
number of revolutions.of the motors. The investigations have demonstrated that:
1) the separating force of the metal on the rolls of the four-high stand is, in
all the cases investigated, below the admissible; 2) the closest agreement with
the experimental data is given by the values of the mean pressures as calculated
by the Golovin-Tyagunov method; 3) the main motors of the mill 2800 are not
utilized to full capacity. -

Considered the type of kinetics of adsorption on
activated carbon in the case when neither external
nor internal diffusion limits the velocity of ad-
sorption. Found by comparing data from exptl'kine-
tic curves of adsorption of benzene at 200 on 6c-
tivated carbon of various grain sizes with corres-
ponding data from theoretical curves, that external
diffusion is apparently not a limiting factor. The

shape of expl curves of adsorption of vapors on
carbon with a grain size that is not too large de-
pends on the velocity of air that brings the vapor
to the adsorbent, and is not limited by the diffu-
sion of mols of vapor from the air,.which is in.
finitely large.

Abstract: Experimental adsorption data referring to 12 different sub-

detail and a good conformity with the experience with the
earlier developed potential theory of vapor adsorption on adsor-
bers with heterogeneous surface 'was shown. The part of the car-
bon structure in the adsorption process was made clear and it
was shown that in the case of well adsorbed vapors (activity

volume is close to one at great p/ps independently of the mag-
nitude of the structural characteristic of the carbon B. The
adsorption of such substance is determined mainly by the total
micropore volume but not by their dimensions. In the case of
little adsorbing substances ( (3~- 0-5) and little p/p.) the
F magnitudes are small and depend strongly on F, i.e., on the
micropore dinen ions, their volume playing a secondary part.
These conclusions determine the selection of carbon activation
conditions for various purposes.

TITLE: On the Rate of Desorption (0 skorosti desorbtsii)
PERIODICAL: Zhurnal fizicheskoy khimii,, 11058, Vol 32, Nr I i , pp 2485-2486
(USSR)
ABSTRACT: The rate of desorption of organic vapors from a layer of
activated charcoal through which pure air is blown is much lower
than the rate of adsorption. Besides another condition (Ref 1)
it may be assumed that the slow course of the desorption is
only explained by the low concentration of the substance on the
particle surface, by which fact a small amount of the substance
is removed per unit of time. To prove the validity of this
the present paper gives a comparison of the data
assumption
,
calculated on the rate of desorption and those obtained from
experiments. The experimental results of the type of the present
investigati.,-ns are best expressed by "he equation of the ad-
sorption isotherm by M. hl. Dubinin and L. V. Radushkevich (Ref
3). Proceeding fzom tbis equation another equation is derived
according to which the desorption curves of benzene vapors are

compared with the experimental data. The measurement of the rate
of desorption was carried out according to a method already
described (Ref 4). The calculated curves are somewhat lower
than those obtained by experiments. It is,, therefore, assumed
that the concentration on the surface as well as in the
interior of the coal grains is the same. As the calculated and
experimental curves agree rather-well it is maintained that
the external diffusion on the surface of the coal particles in
the case of not too high flow rates (of the air) does not
exert any particular influence an the desorption rate from the
layer of the activated charnoal. The residual value of the ad-
sorption and the rate of desorption are dependent on the struc-
ture of the acti-,Tated rharcoal which is characterized by the
constantB w 0 and B (from the above-mentioned equation of the
adsorption isotherm). There are 2 figures., 1 table, and 4
Soviet references.

ABSTRACT: The matter adsorbed in porous sorbents from a flowin,-, ~:as
moves by diffusion in the volume of the pores and on the
surface. Both kinds of transfer proceed simultaneously and
into thei same direction. This paper deals with the separation
of the flows in the gaseous and in the adsorption phase. The
idea of the method is discussed in a few lines. Granulated
charcoal of vapor-gaseous activation was used as a sample for
these investigations. The results of one of the experimental
series are represented by a figure. According to these results,

ABSTRACT: One of the drawbacks of the McLeod gauge consists in the fact
that the mercury contained in the gauge can flow out or pene-
trate into the gauge reservoir as soon as the vacuum is
switched on or switched off. In order to eliminate this draw-
back the author designed a small attachment for the gauge
which connects it to the gas pipe (Fig). The attachment con-
tains a porous membrane (filter Hr 4) that is,penetrable by
air, but not by mercury. There is 1 figure.

TITLE; Meohanism of Mass Transfer in Porous Sorbents
PERIODICAL: Uspekhi khimii, 1960, Vol 29, Nr 3, Pp 404-423 (USSR)
ABSTRACT: This is a survey of papers published during the last ten years in
the field of investigation of the transfer mechanism of adsorbable
gases in porous sorbents. First, the main types of transfer of
nonadsorbable gases are described briefly in order to classify
existing data. The types discussed are: the viscous flow (Refs 7-17)
-table 1; molecular diffusion (Refs 16-25) - tables 2,3; flow of
gas in the transition region (Refs 18,26-42) - figure 1; model of
a porous bodyp mixed transfer - figures 2-5. In the second part of
the paper, the transfer of adsorbable gases is discussed (31,81-99),
the following subjects being treated in greater detail: diffusion at
the surface of the Borbent (Refs OP4707983-659100-123) - tables 4,
5 and figures 6t7; activation energy of the diffusion process in
porous bodies (Refs 44,91,124-131) - table 6 and figures 8#9; some
methods of estimating the size of the migration effect (Refs 90,91,
132-133); flow of liquid adsorbate (Refs 93-98); capillary flow
(Ref 133) - figure 101 peculiarities of water vapor transfer in
finely porous adsorbents (Refs 1249134). By applying various methods

transfer of adsorbable gases was possible. From the existing data a
rough picture of the transfer process can be given for different
ranges of relative pressure and various degrees of saturation. It
would be important to find a relation between the different types of
transfer and the structure of the adsorbent. The finding out of some
rules correlating the rate of tranaf(; '- fith the strength of adsorp-
tion is only a first beginning in the aboye-mentioned field of
investigation. The structure of sorbents has scarcely been investi-
gated from a kinetic point of view. Kinetic investigation methods of
the structure of porous bodies would therefore have to be developed.

TITLE: Sorption kinetics of water vapors on A-type zeolites
PERIODICAL: Akademiya nauk SSSR. Izvestiya. Otdeleniye khimicheskikh
nauk, no. 7, 1961, 1192-1197
TEXT: In the present work the sorption kinetics of water vapors were
examined with a large amount of fillers on a molecular sieve of the type
Linde 5Ay grain radius 1.6 mm. The sorption kinetics was measured at
constant water vapor pressure in vacuum by means of a sorption scale. A
common weighing device, used for examining adsorption isotherms was applied,
provided with an additional volume of,00 1 connected to the system for the
control of vapor pressure. For a more convenient computing of diffusion
coefficients, the grains of the adsorbent were carefully treated to obtain
a cylindrical form of equal height and width. The weighed portion con-
sisting of a few grains was evacuated by means of a mercury pump at 3500C
within 3 to 4 hours~ before the experiment. The increase in the amount of

adsorption was determined by elongation of the spiral spring of the scale
by a cathetometer having a graduation of 0.01 mm. The sensitivity of the
spiral amounted to 2.44-10-3 g/mm.. The experiments were conducted at 00
and 300C. Temperature in the air thermostat was maintained at 200C in the
first case, and at 300C in the second case. Diffusion coefficients were
computed from the diffusion equation for finite cylinders. Within the
examined range of charging, the diffusion coefficient depends in a complex
manner on the amount of adsorption: at the beginning it increases and after
passing through a maximum it decreases. A 300C, diffusion coefficients
have amounts several times higher than at OOC. This indicates an activated
diffusion character. The dependence of the coefficient of activated dif-
fusion on temperature is expressed by the equation
D = Do exp (-E/RT) (5)
E - activation energy; Do - factor before the exponent; R - gas constant;
T - temperature. In case of two different temperatures, the activation
energy of the diffusion process may be found from the equation

D1 and D2 are diffusion coefficients corresponding to temperatures Ti and

that it decreases as the amount of adsorption increases, I5o5teric ad-
sorption heath calculated from the water vapor isotherms at 00 and 300C,
drops within the examined charging range as low as 11 to 10 kcal/M. Experi-
ments were conducted within the charging range of 18 to 24 per cent by
weight of the' adsorbent. The most probable pore radius amounted to 2500
With zeolite grains diffusion takes place in the intercrystalline cavities
and inside the crystals. Experiments were conducted at pressures as high
as 26 mm. Hg; thus, the mean free path of molecules (of the order of
magnitude of 10-3 to 1o-4 cm) was, under such conditions, longer than the
intercrystalline cavities., Therefore transition into the gaseous phase
took place by Knudsen diffusion, The coefficient of the Knudsen diffusion
for a capillary of infinite length is determined by the equation 0
Dk = (2/3) ur (9), u - gas-dynamic velocity of molecules (for water at 20 C,

u = g..1.104cm/sec); r - radius of capillary. From (9), Dolul cm2/sec was
found by introducing the values for u and r,(2500 R). Correcting the finite
capillary length according tp Clausing, (Rej, 10i P. Clausing, Physica
65 (1929)) this amoun't is reduced to 0.4 cm /see. The Henry constant
amounted to 2000 to 5000 within the examined charging range. Hence, the
real diffusion coefficient in the gaseous phase amounted to
De = Dk/H = 0-8-10-4 _ 2'10-4 cm2/sec,
i.e, it was by two orders of magnitude higher than the values obtained by
experiments. It follows that diffusion resistance mainly occurs at dif-
fusion in the crystalline components of zeolite grains. Taking account of
the migration of molecules on the external crystal surface may be only
appraised as an additional argument in favour of this conclusion. Table 2
shows the values D0 for different amounts of adsorption and mean free paths
& in the transition of molecules into an activated state. It is evident
Aat the values of ZN, and, accordingly, D0 decrease as the charging degree
rises. In this case, the decrease of D 0 affects the amount of the diffusion

ADSTRACT: In recovery units with a fluidized bed of sorbent, adsorption occurBs
in the presence of a periodically changing concentration at grain surface as
the sorbent moves from one shelf to another. The authors present the results j
of an investigation of the kinetices of the adsorption of benzene vapors by
AP-3 activated charcoal and NaX zoolite. It was established that the distriixtion
of adsorption as a function of the gradation of concentration is such that it
,increases with every gradation in a more or loss uniform manner, calculated on
the basis of the following datas maxim= adsorption rate for benzene vapors;
0.162 g/g for zoolite and 0.370 g1g for charcoal; cylindrical shape of zoolite
and charcoal grains; grain diameter 3 Mm for both zoolite and charcoal; grain
length 3 nm for zoolito, 6 mm for charcoal; gas (Benzene vapors) flow rate
0.2 m/soo in experiments with zeolite and 0.3 m/seo in experiments with
charcoal. This article was presented by Academician 1-1. R. - Dubinin on'4-Jiino' 196~.

TEXT: The authors recommend that the method of probability should
be used for investigating the conditions of operation of electrical
systems in the case of existence of non-symmetric and non-sinusoidal
loads, which vary at random and are practically independent for the
individual phases, The approach to the solution does not change
when there is a correlation between the phenomena under investigation.
It is stated that this method can be used to obtain the integral
distribution laws for the quantities under investigation from the
given laws of distribution of non-symmetrical and non--sinusoidal
loads and from their maximum values on each phase on the secondary V/_
side of the transformer. The voltage at any point in a
complicated electrical system and the cuVrents in all its branches
can be determined if the load currents Ik are known for all the
three phases at each point k If the system under consideration

components in the i-th branch, Zskj is the matrix of the total
resistances for the points k and j with respect to the
symmetrical components of the currents and voltages of any
frequency, 9 and L-1 are the coefficients which ensure
conversion from phase quantities into symmetric components and vice

For a three-phase system with equal parameters for each element
of all the phases and qqual mutual parameters for each pair of
phases, the matrices Csij and iskj will be diagonal. Therefore,
for any frequency the calculation can be carried out separately for
the currents and voltages for each of the three sequences, using the

the circuit of each sequence g:

Regimes in Electrical Systems
Non-symmetric loading can be constant or variable with time. The
solution is considered for the general case when, in addition to
constant loads of the system, there are loads which vary at random
with time independently of each other. The following two possible
cases are considered: the active and the reactive components of
the current of each single phase load ?I vary independe4tly; the
active and the reactive components of the load current Ibu
relative to the voltage does not vary when this current changes.
On the basis of this method, calculations were carried out at
VNIIE which enabled elucidating the dependence of the voltage and
the current of the positive and the negative phase sequence in the
presence of random single-phase traction loads in electrical
systems. It proved possible to carry out these calculations in a
short time on the "Strelatt computer, for complicated electrical
systems with a large number of widely spaced traction loads.
Comparison of this method of calculation for the express�on without
the imaginary part (which can be calculated graphically) showed

investigations. The here described method can be used
successfully not only for calculating non-symmetrical and non-

electrical systems and also for other calculations of a similar
nature. Acknowledgments are made to N.A.Kartvelishvili and
