TITLE: Making Babbit Bearings by the Method of Plastic De-
formation
PERIODICAL: Mashinostroitell, 1959, Nr 7, pp 36-37 (USSR)
ABSTRACT:. The proposed method of coating the inside surface
of a bearing with babbit is as follows: a babbit ring
is inserted into the orifice of the bearing, and then
C.
two flanges are clamped to both ends of the bearing.
ges has an aperture equal in size
One of these flan.
to the aperture of the bearing in its finished stage.
After that, on the press, with the aid of a stepped
punch, pressure is applied to the butt end of the
ring. Under a pressure of 50 kg/mm the babbit fills
in the:space between the punch and the bearing wall,
firmly covering the latter with a coating of the needed
thickness. Detailed information is given an the de-
sign of the new device and on the technolof- of the
'y
new method. There are 2 diagrams.

The authors investigated benzalazinQ and a number of its
symmetrically formed derivatives Kavirg electro-donor and
electro-acceptor substitutes in various arrangements relative
to the central atom grouping of benzalazine. The color of the
benzalazine derivativips was found to be identical or nearly
identical. A considerable change in the color was observed in
hydrochlorides obtained during the reaction of dry hydingen
chloride with solutioi -2;ine derivatives in organic
-B of benzat
solvents (with exception of the benzalazines which do not attract
hydrogen chloride). The authors obtained mono- or dihydrochlorides
which differed in color from the basic product and were unstable

to the effect of moisture. As is evident from the data gLven in
tables the color of the benzalazine hydrochlorides and their
derivatives is in direct dependence upon the chemical structure
.and especially upon the nature of the substitutes in the benzene
rings of benzalazine and their arrangement with respect to the
central atom grouping of banzalazine and with respect to each
other. Using modem electron devices, efforts were made to
explain the color changes in benzalazine derivatives observed
during their reaction with dry hydrogen chloride. The effect of
hydrogen chloride apparently causes the formation of ammonium
salts due to the arrangement of one of the nitrogen atoms in the
central benzalzine atom grouping.

~'TITLE: The Influence of Eddycurrents on the Commutation of a
d.c. Machine with Shock loading (vliyaniye vikhrevykh tokov

PERIODICAL: Vestnik Elektropromyshlennosti, 1958, No. .4
pp - 5 - 9 (Ju6SR)
ABSTRACT: Previous works have shown that one of the factors that
influences commutation on d.c. machines during shook loading is
disparity between reactive and commutating e.m.f. caused by
eddy-currents in the frame and commutating poles. This effect
is particularly marked in modern drives, where severe transient
processes occur. Attempts have been made to overcome this
influence of eddy-currents by using inductive shunts, also by
making the magnetic circuit of high-resistance steel and by
laminating the commutating pole.
Investigations of different constructions of frame and commutating
poles were conducted to form a numerical estimate of the
influence of eddy currents on commutation. Direct-current
machines, types nH-68, 6 W, 1 500 x.p.n. and U-550, 69 kW,
1 000 r.p.m. were made with various constructions of frame and
Oardl/4 commiltating poles. Tests- were also run on some machines manu-

factured by the Kharlkov Electrical Mechanical Works (XEMZ)
including generator type 116K 215/40, 4'000 kW, 500 r-P.M. with
laminated frame and commutating pole.
The investigations consisted in determining the lag of the
commutating flux behind the load current; the nature of current
distribution in the brush contact; and the zone of sparkless
commutation. The techniques are described. Tests were made
on six variations of machine, type QH-68 with various combin-
ations ranging from solid frame and commutating poles to lam-
inated frame and comnutating poles. Curves of the load-current
increase and the commutating flux of the commutating pole are
given in Fig.l. Curves of diminution of load-current and
commutating flux of commutating poles are given in Fig.2. The
data obtained from these characteristics were used to draw up
Tables 1 and 2, which show the changes in the uncompensated
reactive and excess commutating e.m.f.
Sparking was observed in machines with solid frames or solid
commiitating poles. There was.no sparking when both frame and
commutating poles were laminated. To investigate current
distribution in the brushes, those of one polarity were sub-
divided radially into three equal parts, insulated from one

another and from the brush holders. Oscillograms showing the
current distribution in the brush face with different variants
of magnetic path are given in Figs- 3 and 4. As will be seen
from'Fig-3, when both frame and commutating poles are solidI
the distribution is not uniform. Laminated poles and COMM11-
tating poles improve the current distribution, particularly
when both are used together.
Curves were plotted to determine the enlargement of the zone
of sparkless commutation during transient processes. Compara-
tive characteristics for machine, type OH-68, are given in
Fig,,5, and show how extension of the sparkless zone during
shock loading is achievedby the use of laminations in all or
part of the magnetic circuit.
The investigations demonstrated that commutation during shock-
loading is much improved in machines with laminated commutating
poles and frames, which are therefore recommended for all large-
and medium-sized machines subjected to shock lodings and for
traction motors. Laminated conunutating poles should be used on
all except the smallest machines. There are 6 figures,
2 tables and 4 Russian references.

ABSTRACT: Frog-leg arMalVe w3.nd:Lngs for DC-machines were introduced
at the Xharlko ~lektromehhanicheskiy zavod (Kharlkov
Electro-mechanical Works) in 1933, at the initiative
of Engineer A.I. LevItuo and are now very widely used.
This article attempt,s a close examination and analysis of
commut -leg winding is a
tation-in such machines. A frog
composite winding consisting of a.lap winding and a wave
vrinding.placed in the same slots and connected to the same
commutator. Thus,.four ends,are connected to each commu-
tator aegment,and the presence of the lap and wave comp-
onents does not double the number of.parallel paths. The
conditions that a frog-leg winding must fulfil in order
to operate satisfactorily are then briefly stated.
The most widely used type of frog-leg winding is that
Cardl/5 shown in Figure 1, which also indicates the usual arrangement

of conductors in.slots. Determinations are then made of
the displacement of comtnutation time for individual layers
of the slot. The process of commutation in a slot is
considered 'with reference to the case illustrated in
Figure 2 As the winding rotates, the lap component is
shorted at the instant w1m the brush commences to cover
the commutator bar connected to the r�Sht-hatid side of
the coil; whilst the wave component commences to commutate
when the brush approaches the bar connected to the.left-
hand end of the coil. it is then shown that the layers of
each armature slot commence to commutate in a definite
timelsequence,.as indicated in the lower part of Figure 2.
Formula6 are then derived for the specific self-induction
susceptance of each layer of the slot and also the specific
mutual inductance permeance between individual layers.
Formulae (6), (5),~(8), (9), 110) and (4) show that the
reactive fields constructed separately for the wave and lap
components of the winding differ somewhat in size and shape.

Yindings.
This makes for difficulty in.compensating the reactive
field by auxiliary~p'oles. However, the differences between
the fields are quite small.and.do not much affect the
process of commutation.
So far, the frog.-leg windings considered have been those
of the type illustrated in Figure 4a but use is often
made of the so-called .'cut'. frog-leg winding arzanged as
shown.in Figure 4b. The advantages and disadvantages of
this kind of construction are briefly described.
Suscept-aur-e equations are given for the lap and wave
componeiits of the winding.
A further construction of frog-leg winding illustrated
in Figure 5 is then considered and,the differences in
commutation time of,.IndIVIdual.layers are-determined.
Susceptances are determined for this winding in much the
same way as before: Formulae (19), (20), (21) and (22)
show that the susceptances for the out frog-leg winding
are somewhat less than for that Figure 5. However, in
the cut frog-leg windings there is practically no potential

difference between the first and.second or the third
and fourth layers. Hence,the slot height.may be less
with this than with the other types of frog-leg winding.
Moreover, for all practical purposes, the value of the
specific susceptance.ofthe slot part of any of the frog-
leg windings Is *about the same as in a. lap winding. This
contradicts a commonly held view that the winding of the type
shown in Figure 5 has considerable advantages and it 4S
shown that this idea rises from a misconception. Indeed,
to a first approximation the values of the mean mactive
.e.m.f. of a frog-leg-winding is equal to that of a sir#e
lap winding.
The c6mmutating Iproperties of the different windings are
compared. The mean value of the reactive e.m.f. for all
the types of armature winding-is found to be approximately
the same and none has any special advantages in this respect.
The use of frog-leg windings is recommended where commu-
tation is difficult because they have a whole number of

The lap and wave components of frog-leg wi-ndings are not
uniformly heated. The lap component is located inside the
wavecomponent and so has much higher local heating,
particularly in the end windIng of the uncut frog-leg
winding. The temperature difference between the two parts
of the end i-rinding,iAay be 50 OC, so that the armature
loading must be reduced,as compared with that of a lap
winding.

ABSTRACT: Shock-loading of d.c. machines is experienced in

bad effect on commutation. In most such cases the
comautation problem limits the output.of the machinery,
Previous work on commutation under conditions of shock-
loading is briefly reviewed. Special features of such
commutation are: the appearance of a transformer

The improvement associated with the laminated core
results from the reduced influence of eddy-currents on
the rate of increase of the comi-i-,utating flux; its rate

TITLE: investigation of the magnetic flux in the steel of d-c machines at pulsating

ABSTRACT: A theoretical and experimental investigation is reported of B, H, pi
and losses in solid and laminated steel structures whose windings are supplied with a
pulsating -voltage energy. The problem was investigated by R. 0. Carter et al.
(Proc. IEE, v. 95, no. 56, p. 11, 1950); however, the present article adapts the
results to pulsating -voltage -fed motors. The B/H curve is analyzed, and formulas
for losses are developed. Experimental results obtained witli toroidal cores
IID = 160 mm, OD a 220 mm, 30-mrn thick are presented; five cores were tested:
solid, 5-mm. laminations, 2-mm. laminations, 0. 8-mm laminations, and 0. 75-mm

laminations. Plots of loss vs. ripple factor, loss vs. degree of lamination, and
o~ vs. ripple factor (oe is the phase angle between the current and magnetic flux) are
shown. Findings: Q) In d-c pul sating-voltage -supplied motors, additional. steel loss
increases with the ripple factor; however, the solid portiong of the magnetic circuit
reduce the above effect; (2) The losses caused by the higher harmonics of the
pulsating flux must be taken into account; (3) The lag angle of the flux a-c component
under, sustained conditions, and of the total flux, under transient conditions, largely
depends on the degree of lamination; a completely laminated magnetic circuit is
recommended for d-c pulsating -voltage -supplied motors. Orig. art. has: 7 figures

TITLE: A Polar Spectrohydronephelometer (Polyarnyy spektrogidro-

PERIODICAL: Doklady Akademii nauk SSSRP 1958, Vol 121, Nr 4, pp 634-636

ABSTRACT: This paper gives a short description of a polar spectrohydro-
nephelometer which was designed in 1956 and of some results
of the measurements by means of this apparatus. The polar
hydronephelometer- - an apparatus for transparency measure-
ments - consists ofa vessel filled with the water to be
investigated. The objectives of the condenser and of a photo-
metric device are immersed in this water. The luminosity of
the ground glass of the photometer may be changed by 100 times
by removal or turning of the measuring lamp and by introduc-
tion of a neutral light filter. The condenser sends a narrow
cone of light into the water, If the decrease in light in-
tensity is measured in a turbid water, the light of the con-
Card 1/3 denser is directed straight into the objective of the photo-

meter. The intensity of the scattered light is measured under
various angles 1F with respect to the beam of the condenser.
By some measurements ofthis kind the indicatrix and the
scattering index a can be measured. The absorption index k
may be deduced from the measured values of the index E of
the decrease of the light intensity and of 6. The measurements
in the various parts of the spectrum are carried out by means
of color filters. In order to determine the degree of the
depolarization.of light by water, the condenser was furnished
with a polarizer and the photometric apparatus with an analyzer.
The apparatus discussed in this paper makes'it possible to
investigate the properties of sea water and river water the
extinction coefficient E of which lies within the interval
I
0,1 - 6 m- . The indicatrices may be measured for any angle
between 0,50 and 1450 and for 1800 (backward scattering). Ac-
cording to many measurementsf the properties of the investi-
gated sea water vary considerably near the shore. The indi-
catrices of the scattering.of natural waters are considerably
elongated. The intensity of the scattered light has a mini-
0
mum at scattering angles of - 120 . For other regions of
the sea, the shape of the scattering indicatri:-. depends only

perpendicularly to the interface dielectric -vacuum (z - 0), is investigated
and calculated. Special attention is paid to the generation of supplemen-
tary transverse waves.of exciton origin. In addition to excitation of
exciton,waves, their transformation into electromagnetic waves at the
interface are considered. The system is descri~bed by the Maxwell equations.

the interaction of the particle with the dielectric, consists of common
transition radiation, the Cherenkov radiation, and longitudinal and transveise
exciton waves. On leaving the dielectric these two exciton waves become
transformed to transverse eiectromagnetic waves. A continuous Cherenkov
radiation spectrum occurs on the boundary of the dielectric plate when
p9rticles with sufficiently high speed are leaving this. At decreasing
