ABSTRACT: This Author CertirIcate presents a cargo-handling mast on maritime ehipa.
The mast is equipped with a orane arm, a rotating head mounted on the top of the mast
and a device for shifting the crane arm from one working position to the other
diametrically located working position. The design permits -the crane arm to be
shifted without altering its rigging. The device is made in the form of two rotating
brackets with yokes and with an intermediate pivot (see Fig. 1). The yokes are
fastened to the lower part or the mast.

TITLE: Investigation of the Influence of Composition of Mixed Solvents
on the Rate and Selectivity of the Process of Hydrogenation of
2-Ethylanthraquinonal I
PERIODICAL: Doklady kkademii nauk SSSR, 1960, Vol. 131, No. 6, pp. 1362 - 1365
TEXT: The authors found that the rate and selectivity of the process mentioned
in the title are essentially influenced by the composition of the mixed solvent.
Hydrogenation of the 2-athylanthraquinone ring is favored by dioxane, At 200 and
normal pressure, one of its two aromatic rings hydrogenates in the dioxane mediun.
The authors could not find an octahydro derivative. The formation of the tetra-
hydro derivative starts immediately at the beginning of the process. By addition
of apolar component to dioxane, the reduction of quinone groups is accelerated,
whereas the hydrogenation of the quinone ring is suppressed. On addition of even
small amounts of NqK-dimethyl formamide (0-3M to dioxane, 2-ethylanthraquinone
is selectively hydrogenated. A higher selectivity of the process in apparently
achieved by acceleration of the hydrogenation of the quinone group and by

adoorptive substitution of the hydroquinone molecules. The degree of selectivity
depends on the nature and quantity-of the polar solvent added. In their experi-
ments, the authors used the following solvent mixtures: dioxane-N,N-dimethyl
formamide and dioxane ethanol. -The catalyst was produced by treating a Ni - Al
alloy (50:50) with alkali. The reaction rate was determined by measuring the ab-
sorption rate of hydrogen. The quinones were determined after oxidation of the
catalyzate by means of air with automatic photopolarographs of the type LP-55
(Methods, Ref. 4). Preliminary experiments showed that the reaction rate does
not depend on the intensity of stirring. The reaction order in dimethyl forma-
mide was equal to zero (Fig. 1). Fig. I shows the dependence of the hydrogena-
tion rate of 2-ethylanthraquinone on its concentration in dimethyl formamide.
Fig. 2 shows the dependence of the absorption rate of the first mole of hydrogen
on the composition of the binary solvent. Table I shows that the reaction pro-
ceeds least selectively in dioxane. klready under smooth experimental conditions
(200, normal pressure), 2-athyltetrahydroanthrahydroquinone begins to form. On
hydrogenation in 9C% of dioxane and 10% of ethanol (or equal volumes of dioxane
and ethanol), no tetrahydroquinone was detected even after absorption of
0-95 mole of hydrogen. There are 2 figures, I table, and 4 references, 3 of which

TITLE: Thermal alkylation of cyclopentane with olefins
PERIODICAL: Akademiya nauk SSSR. Izvestiya. Otdeleniye khimicheskikh
nauk, no. 6, 1961, 1146-1148
TEXT: Up to the present time, the alkylation of cycloparaffin hydro-
carbons has hardly been studied. H. Pines and N. Ipatieff (see below)
studied the alkylation of methyl cyclopentahe with olefins in the presence
of H2 so4 (100 @6) or 111F. The reaction proved to be very complicated.
Yu. G. Mamedaliyev and A. Kuliyev (Dokl. AN SSSR, 88, 471 (1953)) as well
as Yu. G. Mamedaliyev and Z. A. Namedova, (ibid., iTT, io63, (1.'957))
alkylated methyl, ethyl, and isopropyl cyclohexane with propylene and
butylene under similar conditions. In the present study, the direct
alkylation of cyclopentane with ethylene and propylene at elevated
temperatures and under pressure was achieved for the first time. Thi
main reaction products were isolated and identified. The influen,@e of

temperature and pressure on the course of reaction was studied. The
alkylation with ethylene prcceeds already at a temperature of 3500C and
under a pressure of 200 atm. At elevated temperaturesand pressures, the
yield in alkylates and the degree of conversion increase. At 11500C, the
ethylene was completely consumed. Diagram 1 shows the chromatogram of
one of the oatalyzates with carbons up to C9, and also its distillation
curve. The main reaction products were ethyl cyclopentane (peak III).
the diethyl cyclopentanes (peaks IV and V), and butyl cyclopentane
(peak VI). A horizontal section on the distillation curve corresponds
to each of these peaks, After elimination of the cycloPentane from the
alkylate by fractional distillation, the following fractions were obtained:
I) mono-ethyl cyclopentane and II) diethyl cyclopentane. The unsaturated
character of the alkylate is not strongly marked. The yield in ethyl
cyclopentsnes amounts to 36 @. (related to the weight of the alkylate) and
to 65 @o (related to the weight of the large fraction). Alkylation with
propylene is more difficult. On distillation under pressures between 200
and 450 atm, easily boiling cracking products, the fraction of propyl
cyclopentane, and the higher boiling residue were separated from the

TITLE@ Thermal alkylation of methylcyclohexane with olerins
under pressure
PERIODICAL: Neftekhimiya, v.1, no.5, 1961, 613-618
TEXT: The authors reported recently that alkylation of cyclo-
hexane and cyclopentane can be achieved thermally (350 to 4500c)
under pressure (50 to 200 atm). Further work on alkylation of
methylcyclohexane with olefins was carried'out to elucidate the
influence of side chains on the direction and ease with 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 propylene 1.4 to 3.2. The
space vel.ocity varied between 0.81 and 0.99 litre/hour for-:--l'
ethylene and 0.52 to 1.43 litre/hour for propylene. All
experiments with propylene were carried out at 450%, whereas for
ethylene the temperatures varied from 350 to 450%. Results show
that the main product of the reaction of methylcyclohexane with
Card l/ 7,

ethylene is a mixture of methylethylcyclohexanes, the proportions
of various isomers differing from their equilibrium concentrations.
With propylene the reaction proceeds with more difficulty and the
yield of alkylate is lower than that obtained for ethylene
(155% of propylene taken and 316% of ethylene respectively).
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 (35000 and
pressure (50 atm). The expected formation during the reaction of
1-methyl-l-ethylcyclohexitne 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 formed by 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 114@ Acknowledgments are

TITLE: Effect of high pressure on the structural trend of
tert-@utyl benzene phenylation
PERIODICAL: Akademiya nauk SSSR. Doklady, v. 146, no. 1, 1963, 105-108'
TEXT: Th.? phenylation of tert-butyl benzene with benzoyl peroxide under
various p:ressures was studied to confirm the assumption that an increase
in presau:re increases the portion of ortho-iBomer, which is supported by
various publications. The method by J.I. Cadogan et al. (J. Chem. Soc
19549 335:2) using atmospheriepressure was repeated. The isomer mixture,
however, -Rae separated by gas - liquid chromatography in a column, 2 m
long and of 5 mm diameter, containing 15% polyethylene glycol adipinate
on diatomite at 1700C, with helium serving as gas carrier (50 ml/min).
The material of the reaction vessel (glass, steel) did not affect the
isomer mixture. The total yield of 42.6% was approximately equal to
Cadogan's value whereas the 2-isomer proportion was lower (17% as
compared to 24%). The abvence of secondary reaction .a bf tert-butyl

the yield in -2-isomer by 2@6 at atmospheric pressure and also at

TITLE ViscGsity chang@@ of the reacting mass in Isoprene p@lyrrerizati:)n
PERIODICAL., Kauchuk i rezina, no. 2, 1962, 1 - 4
TEXT: Results of an investigation on the viscosity change of the react-
ing mass during Isoprene rubber synthesis are submitted. The change is studied
with respect to the duration of polymerization, pdymer content, isoprene supply
conditions and temperature. The isoprene polymerization was carried out in 3-
liter autoclave-, made of 1X9118H (lKh9T18N) steel, with anchor type mixers. The
molecular weight of the polymer was determined according to the viscosimetric
method tind calculated from the formula: M = 5 + 1.162 h, where h is the cba-
racteri;3tic viscosity. The PB-2 (RV-2) rotational viscosimeter was used f,,r
continuous measurement of the viscosity. The viscosity of the HH-6 1PN-6) ra-
librating liquid was measured with a Kepler rheoviscosimeter. Exper@menff;
showed that one of the main factors determining the abs,:,1ute viscosity of the
reacting mass is the concentration of the monomer. The absolute viscosity dct@s
not exc.?ed '-'0 - 40 poise and coincides with the visccsities of solutions in the

oscillations in an automatic -control system with a controller

DZW Z(T2D + U)@ + kWD*-+ hp
The possible hunting ranges of such a system on the plane of the
parameters k,X of the controlled variable and the controller were
Card 112 examined by B. V. Bulgakov and by the author (Avtomekhanika i
S0V1/l.'4 58 -1 'N
On the Stability of Periodic Motions of One Automatic -control System
telemekhanika, 1949, Vol 10, Nr 5). In their study they investigated the hunting
stability by means of period- averaging of the variables. The paper now under
review is. devoted to a substantiation of the possible applicability in the above-
mentioned problem of the averaging method, for which purpose the author computes
the free and linear terms by expansions according to powers of the small para--
meter 11 of the characteri.;tic indices of the variational equations; the latter are
set up with reference to the periodic SOILItiOn of the system. The solution of the
variational equations is set up, as usual, in the form of series according to
powers of it . The free terms and the coefficients of the f' rst po%ver in the expan-
sions of the characteristic indices according to powers of ji. are found as the solu-
tions of homogeneous and, respectively, nonhomogeneous linear differential equa-
tions with constant coefficients, It is shown that of the four Routh-Gurvits inequali -
ties three are satisfied automatically for either oscillatory amplitude, whereas the
sign of the fourth is found tc be in accord with one of the two possible amplitudes,
while it is oppqsitea@o the sign of the other amplitude. Here it is found that the
expression-of the fourth Routh-Gurvits criterion, as obtained from the linear eval-
uation of the characteristic indices, and its expression as obtained by 0w
method, coincide in accuracy except for an essentially positive factor. The smal.1
amplitude oscillation is unslable, the large -amplitude oscillation is stable.

ABSTRACT3 The flying machine may be an aeroplane or a
helicopter which has a main body and a chassis with
six degrees of freedom of relative motion between them.
The relative motion may be intentional or forced due
to deformations. The landing base also has a main body
supporting the actual platform capable of motion with
six degrees of freedom relative to the main base which
may be the deck of a ship or a balloon carrier.
Accordingly, apart from the coordinate system fixed in
space, four coordinate systems are definod. The
aircraft chassis may be defined by the instantaneous
position of three independently displaceable landing
wheals. Definitions of Euler angles are introduced to
specify the angular position of the aircraft and the

ABSTRACT: Gyroscopes with two degrees of freedom are used for
measuring tho absolute angular velocity of bodies such
as aircraft. The static theory of the gyroscope with two
degrees of freedom rests on the proposition that,at each
instant, the deviation of the instrument frame from its
reference position in the body (aircraft) is determined by
its relative equilibrium under the action of the gyroscopic
moment and the moment of the restoring force. It is
stated that this proposition is acceptable to sonic extent
when the gyroscopic device is used solely for the
stabilization of the angular position of' the body (aircraft)
in space and when the disturbances acting on the body are
relatively weak. When it is desired to control
non-stationary angular motions of the body or when the
Card 1/3 disturbances are pronounced, the evaluation of the angular

SOV/179-5 9--5 -1-3/4 1
Contribution to the Dynamics of a Gyroscope with Two Degrees of
Freedom
velocity of the body by the static theory can lead to
noticeable errors and the appearance of false signals.
Moreover, the deviations of the geometry and mass
quantities of the device from its ideal (desig-n) values,
which are found in real apparatus, cause additional
distortions in the results of measurements of the angular
velocity of the body. The conditions for the appearance
of false signals at arbitrary linear and angular
displacements of the body and the consequences of the
chief deviations of the real properties of the device
from its design are examined in the present paper.
The gyroscopic device under investigation has a rigid
gimbal frame. Its pivoting axis is neither necessarily
central nor a principal axis. The gyroscope and gimbal
axes are not perpendicular. The problem is fQrmulated in
terms of finding three distinguished axes in the system,
namely the directions of the angular velocity vector of
the frame known as the axis of absolute insen4;itivity of
the gyroscope (when the frame does not respond to ttie

velocity of the body, the angular velocity of the
gyroscope and the components of the linear velocity of
the origin of it coordinate frame tied to the body), the
axis of transferable insensitivity (when the frame does
not respond to the above quantities except the angular
velocity of the gyroscope) and the axis of limited
insensitivity (when -the frame does not respond to some
values of the above quantities but responds to others)
respectively. An analysis is presented by which these
axes can be found. It is shown that, under certain
conditions, the frame of the device w-411 rest in the
aircraft performing a banked turn. In order to measure
the three components of the angular velocity of' the body
(aircraft) it is necessary to instal three gyroscopes
with two degrees of freedom each and also to introduce
a computing system which evaluates these components by
following a prograim' - determined by a system of three
equations of the type of Eq (1). There are 3 figures and
3 Soviet references.

ABSTRACT: Referring to previous publications by the same author
and to R. E. Robertson (Ref 3), the control of a free
solid body is considered by means of auxiliary
solid bodies rotating about axes fixed in the free
body and driven by torques which are internal in
relation to the free body. The problem is that of
.finding the required laws of variation of the angular
velocities of the rotating bodies such that a given
motion of the free body results. This prescribed
Card 1/3 motion is expressed by the three Euler angles as /13

functions of time. The resultant external moment on
the free body about the centre of mass of the system
is zero and therefore the total angular momentum
remains constant. Three rotating bodies are sufficient,
and the equations from which their speed variations
can be derived are given in this case by Eqs (3). A
special case is considered with three bodies which
rotate about the principal central axes of inertia of
the free body, At the initial instant of time the
rotors are in a. state of relative rest. If the
assumption is irtade that one of the Euler angles remains
unchanged from the beginning, it follows that, in
order to make the body exectite a given motion in
terms of the remaining two ai,,Sles (angle of yaw and
angle of pitch) it is necessary to drive. not only two
rotors but all three. The third rotor is needed to

TEXT: When the linear acceleration of a given point in a body moving
about in an arbitrary manner is to be determined, errors arise for two
reasons: 1) due to the error arising in measuring and recalculating the
pickup position, and 2) due to the deviations of the measuring axes in
the body from the navigation axes. The latter errors have a purely geo-
metric origin. This geometric problem is investigated here. The compo-
nents of the linear acceleration of the body are assumed to be measured
at the three axes (the latter being not connected in any way with the
body and not parallel to any plane). The problem wan to find the com-
pon.ents of acceleration at the axes-@fafixed coordinate system, with
reapect to which the body acceleration is measured. It is pointed out

that the solution of such a problem is specifically required to fix the
tolerances when assembling acceleration pickups in the apparatus. Two
coordinate systems: one(XY4 fixed and the other (xyz) connected to the
body (navigation coordinate system) are introduced (Fig.2). The problem
is solved with the aid of linear transformations with matrioes. Equa.-
tions are obtained with the aid of which it is possible to oalculate
the error of measurement due to the nonagreement of measuring axes and
navigation axes. The publication of this article was recommended by the
