TEXT: The dependence of the prolonged (Ewing type) magnetic viscosity on the
dimensions of the samples was measured by means of an astatic magnetometer in Ar-
mco-iron annealed at 8000C and slowly cooled. It was found that the mqgnetic vis-
cosity increases with the relative length of the samples: the ratio of the viscous
portion of magnetization to total magnetization incieases, and the process of time
variation of magnetization is slowed down. Thus it is necessary to distinguish the
magnetic viscosity of the substance and the magnetic viscosity of the sample.

TITLE: --rVe-tho'dfor'Increasing the Roadability of Wheel Automobiles
(Sposob povysheniya prokhodimosti koleBnykh avtomobiley)
PERIODICAL: Avtomobilinaya promyshlennost', 1958, Nr 12, PP 13-15 (USSR)
ABSTRACT: The roadability of wheel automobiles is increased by using
thin-walled tires of large profile with central regulation of
the air pressure. The roadability of the automobiles
ZIL-151, ZIL-157 and ZIL-121B is here compared. If the
pressure in the tires 12,00 - 18 is reduced from 3;5 to
0-3 kg/cm , the supporting surface of the wheels increases
sharply (Figure 1). The reduction of the specific pressure
decreases the immersion of the wheels in the ground. At a
pressure of 1 atm, the immersion in sand is only 50 mm
(Figure 2). The resistance to the movement of the auto-
mobile on sand is lowest at a pressure of 0.75 atm. On snow,
the minimum is at 1-5 atm (Figure 4). A reduction of the
tire pressure from 3-5 to 0-75 atm lowers the resistance of
the ground 9 times in the case of sand, and 3 times in swamps
(Figure 5). The traction power of the automobile ZIL-151 at
reduced tire pressure is 3,200 kg on meadows, 2,800 kj; on
Card 1/2 Band, and 1,400 kg on snow. Further improvements may be

The authors developed the scheme and designed and
tested the model of an optical installation intended
for the high-speed macro-cinephotography of remote
objects (applicable to the cameras SKS-1 and FP-22).
In addition the authors show the possibility to pro-
duce, with the aid of FP-22 cameras, macrophotos of
a non-luminous object in reflected light with a fre-
quency of 100,000 frames per second, on a scale up
to 3:1. As to the latter, the authors' report is
based on investigations carried out by Candidate of
Technical Sciences, X.F.Romanov, of the Nauchno-iss-
ledovatellskiy institut tekhnologii i organizatsii

proizvodstva (Scientific Research Institute of the
Technology and Organization of Production). The
authors used the scheme illustrated in diagram 1.
The given scheme can be divided into two sections,
the left for projection and the right for photographing,
the back principal plane of lens 3 being at the inter-
face between them. In the lef-~ section, objective 2
forms an inverted image of object-1 in the back prin-
cipal plane 4 of lens 3, which in this way appears as
a kind of transparent screen concentrating the rays
on the camera objective. Lens 3 is characterized by
the fact, that under given conditions it does not
appear as an inverting system. The image formed by
the camera objective, therefore, is erect. In this
way a system with a very great equivalent focal
Card 2/4 distance has been obtained. Such a system is neces-
sary for macrophotographs of comparatively-remote ob-

TEXT: In the authors' opinion, the stability of motor fuels to oxidation
is a most important probiem, They therefore studied the antiox4Ad4-zjng
properties of some pyrazoline derivatives in their capacity as inhibitorn,
The authors first obtained numerous pyrazolines having no subs-~ituents in
position 1. and then such having different substituents in this position.
The following compounds were synthesized as possible inhibitors:

Derivatives of pheny! thiocarbamides of various pyrazolines were obtained
by the action of phenyl isothiocyanate upon these pyrazolines (Ref, 5),
In a similar manner, the following compounds were obtained from the cor-
responding pyrazolinea: 1--carbamida-3-phenyl pyrazoline and 1-phenyl
carbamido-3-phenyl-4-ethyl pyrazoline (Ref., 2), 3-amino-1-phenyl
pyrazoline was synthesized from acry2oni-trile and pheny2 hydrazine (Ref.6).
1,3,5-triphenyl pyrazoline was obtained by interaction of benzal aceto-
phenone and phenyl hydrazine (Ref. 7). The efficienoy of the preparations
examined was estimated by comparing their inhibiting effect with the
efiect of para-oxy diphenyl. amine, which was taken as a standard, as well
as with the effect of 2,6--ditertiary butyl74-methyl phenol. Two samples
of moter fuels A and B were taken, the properties of which are given in
Table 1. Sample A was prepared by intermixing equal amounts of fresh
distillate of thermocracking and of the benzene-ligroin fraction.
Sample B was prepared by intermixing the same amounts in a ratio of
30 : 70. Both samples were inhibited by varioug additions on the day of
their preparation. The additions were allowed to dissolve in the motor
fuels by being added as benzene solutions, Benzene was taken in an amount
of, ru 0.1% of the fuel volume,. The effect of stability of samples A and B

was examined first. For this purpose the authors studied the inhibited
motor fuel for its stability to oxidation by determining the induction
period on the basis of roCT 4039-48 (GOST 4039-48) within 6 h, The content
of potential resins in the motor fuel was determined next. Results show
that some,pyrazoline derivative samples have a considerable inhibiting
effect. The best results were yielded by the use of 1-phenyl thio-
carbamido-3,5,5-trimethyl pyrazoline. In the sample inhibited with this
substance, the resin formation appeared only after two months, while
resins in a noninhibited sample increased with uninterrupted intensity
throughout the whole storage time. There are 3 tables and 7 references.

were transformed to 70%. A concentrate boiling between 120 and
185 0 was obtained from the polymerizate (yield 85-90%). Table 1
shows the resulting (mostly ramified)structures of isodecenese
Table 2 shows their,physico-chemioal properties (the raw material
was fraction 6 of the thermal cracking and benzene). isomeriza-
tion and hydro-dehydro polymerization of the olefins were ascer-
tained as side reactions. 2nd stage: alkylation. Aromatic hydro-
carbons (benzeneq toluene) were alkylated by means of the iso-
decenes produced (Refs 3-5)o The best conditions were: 97%
H2 804, reaction time 2 hours, ratio benzene:isodecene - 5:1. Tem-

perature 10-20 4, The alkylate amounted to 140% by weight of ole-
fine or 90% of the theoretical yield. A fraction boiling between
1800 and 3500 was obtained from the alkylate as a concentrate of
isodecyl benzenes (85% of the alkylate). It chiefly consisted of
mono-substituted derivatives of benzene (Table 2). on using alu-
minum chloride as catalyst the yield was higher and attained
97-90. Disproportionation occurred as side reaction. 3rd stage:
hydrogenation. The alkylate concentrate was hydrogenated on 2
catalysts: a) nickel catalyst. The optimum conditions were: pres-
sure 7 atmo molar ratio hydrogen:alkylate - 2.801 150-2000.

TITLE: Thermodynamic characteristics of niobium oxides
(equilibrium with hydrogen, and electrochemical measurements)
PERIODICAL: Dokl~dy Akademii nauk SSSR, v. 136, no. 6, 1961, 1372-1375
TEXT: As published data concerning the reduction of niobium oxides are
insufficient, and the equilibrium of low niobium oxides with hydrogen has
not yet beeen studied at all, the authors report on the reduction of
Nb205 in equilibrium with 112 to NbO, as well as on the measurement of emf
bf a galvanic call of trbO and metallic niobium. The equilibrium of
niobium, oxides with hydrogen between 1200 and 15500C was studied in a
circulation apparatus described in Ref. B. The samples were placed in a
molybdenum furnace on a platinum base in such a manner that they touched
the Pt in a few places only, and were reduced in a hydrogen flow. The
total composition of the reaction products was determined from the

increase in weight of the sample on annealing in air, the phase
composition by means of X-rays. Two stages of reduction of Nb205 were
ascertained- 2.5NbO 2.4+H2 ---3P2-5NbO2+H20 (1), and NbO 2+H 2--->NbO+li20 (11).
Fig. 1 shows the logarithms of the equilibrium constant K p = PH 2O/Pil2
as a function of composition. Between NbO 2.4 and NbO 2.5' Kp changes so
quickly that it could not be measured accurately. For the polytherms of
the equilibrium constant of the two stages, the authors found the
equations: log K PI = -15050/4-575T+1.3306 (1480-16730K);
log KPII -29490/4-575T+1.3334 (1673-18230K), and obtained therefrom:

ABSTRACT: The author reviews the literature on vertical-axis (cycloidal) propellers
and considers the plane problem of a propeller with an infinitely large number of
blades under light loading. Under these conditions, the velocity field generated by
the operation of the propeller outside its slipstream is equivalent to the field of
vortex-sink combinations distributed around the circumference of the wheel. The -velo-
city field inside the strearn is derived from the first field by addition of a certain
plane-parallel flow. Both the law for the distribution of vortex-sink combinations
and the given plane-parallel flow are simply connected with the distribution of cir-
culation around the perimeter of the wheel. Formulas are given for calculating the
inductive velocity and inductive bevel of the flow at the blades and also for the
forces which arise at the blades assuming a given distribution of circulation around

the perimeter. The variational problem of optimiuri distributJon of circlilatin.- i,~; cnn-
sidered -Wbere inductive losses are reduced to a ininimum. It was foiuffl that ol)timunl
distribution of circulation takes place when the circulation densities X(O) at sym-
metric points of the leading and trailing semicircles differ from one another b." a
constant value which is equivalent to uniform distribution of the induced velocity at
infinity across the slip stream. A comparison of the optimum distribution with the
simplest type of sinusoidal distribution (induced velocity at infinity distributed
across the slipstream in an ellipse) shows that the inductive efficiencies at small
loads differ only slightly. ItJ3 found that the torque of the propeller is ccm-
pletely determined in the general case by the coefficient of the first term in the
expansion of X(O) in a Fourier series, while the efficiency is determined only"by the
asymmetric part of the function X(6). The symmetric part of this function affects
only the transverse force (drift force). Formulas are derived for forces and moments
and also for the necessary angles of attack for the blades assuming a given distribu-
tion of circulation. It is assumed in the calculations that the length of the cord of
the blade is small in comparison with the shortest radius of curvature for its cy-
cloidal trajectory. Orig. art. has: 6 figures 1145 formulas.

ABSTRACT: The author studies the problem of determining the heeling of a tcrwed ship
under instantaneous tension of the taw cable at an arbitrary angle to the diametric
plane. It is assumed that the boat travels under its own power up to the jerk with
respect to a weakened cable whose weight and elasticity arc! not considered. Jerking
is assumed to consist of two stages: inelastic impact and post-slamming motion dur ng
vhich time the ship undergoes maximum heeling. A system of differential motion equa-
tions is derived for the post-slamming period and solved by nurnerical methods. It is
assumed that if post-slam heeling rates are known, then rough estimates can be made
as to maximum heeling of the'ship. The linearization results of the system'of equa-
tions for post-slemming motion at any Jerking angle which is not very small can be

estimated only after model testing. Model testing is being conducted at the present
time to determine values for position force factors and resistance moments. The de-
termination of these factors along with jerking sway data could be used for numerical
Lntegration of the derived equations. Orig. art. has: 2 figures, 136 formulas.

TITLE: The effect of the residual austenite on the wear resistance of steel
surfaces strengthened by case hardening
PERIODICAL; Referativnyy zhurnal, Metallurgiya, no. 3, 1962, 37, abstract 31227
('!Sb. nauchn, rabot. Mosk. in-t nar. kh-va',' no. 20, 1961, 106-112)
TEXT: The study of the effect of the residual austenite on the wear
resistance of a case hardened layer was carried out on steels 20, 30, XF T (KhGT),
12Y2H4A (12Kh2N4A) and i8XFT (18KhOT). Different amounts of residual austenite
were received after case hardening the samples at 9500C during ~ hours 30 minutes,
with a subsequent hardening. The hardening at 8Z5, 820 and 775 C was carried out
with a cooling down after case hardening, at 0,50 C - directly from the cementa-
tion case and at 1,050 0C - after heating up from the case hardening temperature.

The samples hardened under these conditions were tempered at 200 C during 1 5
hours. The microstructure of the case hardened layer at hardening at 1,050 C
consisted of isolated sections of coarse-grain residual austenite and large
0
martensite needles. A decrease of the case hardening -temperature to 8r5 C

reduces the amount of residual austenite. At the hardening from the cooling
down'temperature of 8200C a structure consisting o .f a fine needle-shaped
martensite, a small amount of the residual austenite and of globular carbides
in the form of small inclusions was obtained. A considerable increase in the
amount of residual austenite obtained at hardening at high temperatures leads
to a decrease of the wear resistance of the case hardened layer. The most wear
resistant is a case hardened layer with a structu-re consisting of martensite,
fine-dispersed carbides and 20 - 30% of residual austenite in the form of fine
grains. An increase in the amount of residual auBtenite over 30% reduces the
wear resistance of the case hardened layer, and ite decrease has a favorable
effect on the wear resistance.

TEXT: The author investigated the resistance to wear of the cemented
steel grades 18xrT (l8KhGT),-3OXrT (30MOT), 12X2H4A (IM20A) and 20
used for gears and other machine parts, depending on the carbon concentration
in the surface layer and on the alloying with carbide-forming elements. The
tests were carried out on the MK(MI) friction machine with specimens 40 mm in
diameter and 10 mm wide, the load on the specimens being 75 kg. It was found
that the wear resistance of cemented steel rises when the C-concentration in the
surface layer is increased up to I - 1.2%; at C > 1.2% the wear resistance in-
creases only insignificantly. The resistance to wear depends also on the degree

higher wear resistance than that of the steei grades IBKhGT, 3OHhGT and 20.

TEXT: The investig_~tions were carried ut with specimens made of the steel
grades 18 )FT (18MGT), 3OXrT ~3M%GT), 12_K2H4A (12K-t2N4A) and grade 20 steel.
After cementation at 9500a for 5.5 hours, the specimens were hardened at 1,050,
950, 875, 820 and 7750C with zubsequk.nt tempering at 2000" for 1.5 hours. The
amount of residual austenite in the surface --ayer was determined by an X-ray
diffraction phase analysis, while the resistance to wear was determined by dry
rolling friction with 10,clo sliding. It is shown that, depending on the hardening
temperature, the amount of residual austenite in the surface layer varies in the
same steel grade over a wide range. In the 18KhGT grade steel the amount of re-

sidual austenite in the surface layer changes fron 6r,:% a hardening temperature
of 1,0500C to 25% when hardening takes place a-z 32000C, 4rile the hardness changes
correspondingly from HRC (?) to 60 [Abstracter's note; Obviously, the first
magnitude is missing]. With such a reduction in residual austenite the resist-
ance to wear increases. However, with a further reduction in residual austenite
the resistance to wear decreases. This regularity can also be observed with the
3OXhGT grade steel. 7he wear resistance of the grade 20 steel increased by up to
15% when the residual austenite was reduced in the cemented layer:. With the
12M22AA grade steel the wear resistance of the cemented layer increased consid-
erably if the amount of residual austenite is reduced from 85 to 55%. A further
reduction in residual austenite down to 15% results in an insignificant increase
in wear resistance. It is pointed out that the cemented layer shows a maximum
wear resistance if its ---racture is composed of martensite, finely dispersed
carbides and 20 - 30% austenite in the form of fine grains. If the re-
alaugl austanite oontent excuadd 30% the resistance to wear decreases. lAss than
30% residual austenite in the form of uniformly distributed inclusions affect the
wear resistance of the cemented layer in a favorable way. There are 2 figures.
