TEXT: Cable rubber;ognd.cable constructions were subjected
to gamma radiation from 0 in a' source with an outpxit of -
21 000 g-equiv.rads. The specimens were irradiated to a'd6sage
of 0.3 Mrad/hour. Radiation was found to cause some chemical
changes in cable rubber which progesssively impaired its physical,
mechanical and electrical properties. Radiation doses up to
50-100 Mrads on specimens in vacuum or immersed in water, causes
Smaller change in the properties of rubber than does irradiation
in air. This indicates that oxygen participates actively in the
processes that occur in rubber subjected to ionising radiation.

TITLE: The Dipole and 3-Electrode Diagrams of Electro-Profiles
Obtained by the Method of an Asymmetric, Straight Line BAMN.
PERIODICAL: Izvestiya kkademii nauk SSSR, Seriya geofizicheskaya,
1959, Nr Gs PP 872-879 (USSR)
ABSTRACT: The profile BAMN (Fig la) can be arran ed as a combiLa-
tion of two-3-eleetrode installations BM14 and AM
(B4 00 ). The relation between the apparent resistance's
pk(B) and Pk(A)' to Pk(BA) can be determined from Eqs (1)
to (3), from which the basic formula (4) can be derived. The
relationship'of, t2/11 to the~apparent resistance can be
determined from Eqs (5) to (7). The solution of the latter
is found as Eqs (7a), (7b). This is illustrated-in Fig 2~
~Fio, 3 shows the comparison between the results obtained by
a dipole-method with that of the 3-electrode method. Fig 4
shows. a similar comparison of results obtained for the No-ro-
Sergeyevskity coalfield in the Kuznetsk Basin (1 - area

where the difference between the two methods is negligible).
For the geo-electric profile where the apparent resistance
increases with an increase of-distance, the precision of the
diagr�Lms of the 3-electrode method improves when the relat-
ion -t2/tl is small.' Therefore, the method can be applied
in comparatively small areas. There are 4 figures and 4
Soviet references.

TITLE: Calculation Method of the Diameter of a Continuous
Glass Fiber (Metod rascheta diametra nepreryvnogo

PERIODICAL: Steklo i,.kera-mika, 1958, Nr 12, PP 13 - 17 (USSR)
ABSTRACT: The dimension method, first adopted by Professor
L.S.Eygenson*in connection with the conditions of
vitrification, was used for the solution of this
problem (Refs 1 and 2). This method is based on
results obtained from experimental investigations.
Formula (1.) generally represents the dependence
of the fiber diameter on the parameters determined in
the experimental way. By a number of mathematical
transformationst the authors obtain formulae (2)
and (3). The authors further describe the experiments,
contained in formulae (1) and (2), which were

perimental values. By*a further transformation of
the formulae, the authors obtain formulae (4) and
(5), by which the values of the coefficient, K
as well as the diameter of the fiber can be
calculated. Tables I to 6 show the vr-lues of the
drawing velocIty (w) I the fiber diameters obtained
both experimentally (d. exp) and by calculation (d cal)'
using various annular draiving dies and the same
.glass mass temperature of 12400. The average
deviations of the experimental from the calculated
values amount to 6.7% and 3-5FIfo. There are 6 tables and
2 $,oviet references.

TITLE: Optics A New Field of Application for Glass Fiber
PERIODICAL: Steklo i keramika, 1960, No. 9, pp. 19-21
TEXTs A comprehensive study has been conducted lately at the
Inatitut
steklovolokpa (Institute for Glass Fiber) for the production of
light-
conductinAlass fibers, utilizing t optical properties. Luminous
energy can be transmitted by means of a light-conducting texture
with
arbitrary.poBition of the fi.bers...Pictures can be transmitted
by such a
texture at-a suitable:position of the fibers in it (Fig. 1). The
light
pipes must exhibit high transparency and high resolving power. The
resolving power of the light pipes is determined by the number of
discernible target lines, which fall to Imm. of the image field.
The
utilization of glass fibers as light conductors is based on the
pheno-
menon of the inner total reflection$ as can be seen from Fig. 2.
The
angle of aperture of the rays penetrating into the fiber is the
greater,
the bigger the difference of the refractive index of the
glass-fiber

material and the surrounding-medium. Investigations by A. L. Korobko-
Stefanov showed that the electromagnetic fields of the light wave do
not
stop at the separation boundary, but propagate within the medium.,
The
investigation results of the transparency of textures from fibers of,
various diameters, from glasse a of various compositions with various
fiber casings are tabulated. The coefficients of expansion of the
glasses
and their oasinga must be approximately equalp to prevent the
forming of
cracks. Optical glass fibers of small diameter with high refractive
index
in a thin optical glass casing with low refractive index must be
placed
in regular order to obtain light pipes with high resolving power and
high transparency. The elimination of the aberration of optical
systems_
is mentioned among the many problems which can be solved by means of
fiber light pipes, the paper by G. G. Slyusarev being mentioned. Thf
light pipes can also be used in electronic optics. There are 2

the authors studied the distribution of activity by the groups
of
spinnerets, and its change with'time. The glass fibers were
wound on a
spool. The spool axis formed an angle of 35 - 450 with the
front of
spinnerets, The activity of samples was measured on aB -2 (B-~)
plant by
means ofX-1 (AS-1) and MBFL) counters. Uranium oxide and
45
Ca verw"iised as indicators. Fig- 4 shows experimental results
obtained
with a pellet activated by UO 2' Further experiments were made
with
C&45 sinde the greiLt,difference between the atomic weights of
uranium
and the glass elements became clearly noticeable in feeding
with several
pellets. The experiments, integrated by data of temperature
distribution
in the glass crucible, permit a probable diagram to be plotted
for the
flow of glass. Temperature distribution measurements were made
under the
supervision of L. G. Zhivovt Candidate of Technical Sciences.

ABSTRACT:
A new standardised method of
making thermal

calculations on boiler sets has recently been
published.

This has been compared with experimental data consistihg

of extensive experimental material on the investigation

of
radiation heat exchange in industrial furnaces and in

experimental
installations obtained in the Soviet Union

and other countries
between 1925 and the present time.

The experimental data covers
various furnace

constructions, types of fuel, methods and
conditions of

combustion. The experimental data is divided into
three

classes according to its reliability. The first Class

of
reliability relates to investigations in which the

quantity of heat
received by radiation receiving

surfaces in a furnace is evaluated
by both calorimetric

measurements and by the thermal balance of the
furnace

provided that there is sufficient agreement between the

results obtained by the two methods. The second class
of reliability relates to tests in which the measurement
of individual components of the heat balance were
determined by a simplified procedure. The third class
._'ncludes the least reliable material obtained either
.4.
during short tests or based on experiments that were
not sufficiently accurate. This-classification was
necessary in the early stages of development of the
procedure of calculation. The main characteristics of
the experimental material are simmarised in a table
I,wklich gives on the one hand the types of fuel used and
the method of combustion and on the other the number of
experiments and variousIfurnace conditions. The formulae
that form the basis of heat exchange calculations in
furnaces are given and developed. The results are
plotted in graphs and compared with experimental data
on heat exchange in furnaces. One graph relateb to
combustion of gaseous and liquid fuels and the other to
all data on solid fuels. The graphs show that the
fundamental design formulae are in satisfactory agree-
ment with the experimental data. Calculated and
experimental values for the gas tbmperature at the outlet
from furnaces are compared in two further graphs, With
a few exceptions the divergence between calculated and

experimental values doeS not exceed + 1000C and is in
most cases less than 50 Ca It shoulU be mentioned that
the absolute error in the experimental determination of
the mean gas temperature at the ou8let from a furnace
is also usually not less than + 50 C. Good agreement
is shown between experimental Zaterial relating to all
three classes of reliability with reSUltB obtained from.
tests of1the first and second classes. Reasons for
such divergences as exist are explained. Analysis of
the'deviationa between calculated and experimental
outlet temperatures show that.the standard method of
calculating heat exchange agrees well with available
experimental figures. The accuracy is poor for some
small oil burning furnaces because the calculation is
based on mean values of certain variables which are of
great importance in small furnaces. The standard method
of calculation permits sufficiently accurate evaluation
of outlet gas temperature in dependence on the
constructional features of furnaces, the types of fuel
and combustion con ditions-' It should be noticed that the
experimental data relates mainly to -older types of
furnaces. Not enough data is available.on new types of
furnace such as cyclone furnaces, pulverised fuel furnaces
with rotating burners and rapid combustion furnaces.

oxide. There are no indications that the composition of 3
mixtures, complying with the aforementioned conditions, is
always possible# and if feasibleg most likely not with all

its value, however, it would be more accurate to call this a

the computation may be fully replaced by graphic constructions.

TITLE: Magnetostriction 13i~ive ofMicroteedzj~
~PERIODICAL: Stanki I instrument, 1960, Nr I, pp 18 20
TEXT: The authors point out that t1he machining accuracy of parts
depends to a
great extent on..the possibility of very small displacements of
tools and
blanks. Small feeds make It even possible to correct the setting of
tools
in order to compensatefor the wear., With the aid of
magnetostriction. a
microfeed drive is obtained which ensures stable minor
displacements of
tools and blanks. The principal layout of the device, based on
the,*1liange
in the length of a ferromagnetio.nickel rod in direction of the
Induced
magnetization, is,shown in Figure 1. A description of the
magnetostriction
drive (magnetostriotor) is given. By using microfeed drive it is
possible
to effect a successive displacement of the movable parts of the
machine tool
during an.automatic operation cycle. The minimum feed necessary for
such a
displacement corresponds to the magnetostrictive elongation of the
nicliel
rod during one cycle of magnetization, while the total displacement
of -the
Movable machine tool part during repeated cycles of magnetization
is limite(
Card 1/4 only by the free length of the rod, The operational
characteristic

Magnetostriction Drive of Microfeeds S1121160100010.11011001
of the magnetostriotion drive is determined by the following Pmetionst
1) the variation in magnitude of magnetostrictive elongation due to
different physical-chemical properties of the rod material and
variations
in magnetizationof the coil field; 2) the effect of the resisting
force
on the magnitude of mierofeed. Figure 2 shows tte ratio of relative
magneto-
strictive elongation A_nf for various materials,
L
The authors state that the limiting values of relative elongation of
various
ferromagnetio materials mn be increased by a suitable thermal or
mechanical
treatment of the rod blanks. The operative qualities of the
magnetostriction
drive with nickel rod were analyzed on a special device (Figre 3a)
which
was designed and constructed,at the Odess SKB-3 LaboratoryJ" The
electric
circuit of the device is shown in Figure 3b. Lever-type microgages
(with
graduation values of 0.001 an) were used as measuring instruments,
recording
the motion of the,.rod. Besides, armature of electroinduative
piak-ups,
conneoted to the phase-sensitive cirouit, were in contact with the
two face-3
of the rod. Figure 4 shows the function characterizing the variation
in
magnitude of magnetostrictive elongation when the magnetization of
the coil
field is varied, in the case of abseiice of axial resisting forces.
The effect
of the force 0, gripping the magnatostriotor rod during the feed
action, is
Card 2/4 illustrated by a graph shown in Figur-- 5. It is evident
frow the Graph that,

80229
Magnetostriction Drive of Microfeeds 31121,160100010-1101/00-1
if.the resisting forces are increased, the magnetostriotive
elongationof
the rod is reduced according to a law approaching that of linearity.
The
authors emphasize that an important operative characteristic of the
machine
tool is the stability of the miorofeed. Repeated measurements of rod
elongation at.different intensities-of the magnetic field and duration
of
cycle (Figure 6) showed that the limit of errors of miorofeed does not
exceed 10%, while the average magnitude of error of some displacements
amounted to approximately 2 - 3%.' Figure 7 shows an oscillograph
recording
of the microfeed process. As a result of their investigations the
authors
draw the following-conclusions: 1) At a constant load Q, generated by
the
forces resisting to the feed, it is necessary to select, the
oross-sectioa
of the nickel rod in such a way that the rated stress in it should not
exceed d- 3 1 4 kg/mm2. In this case that load does not lead to sub-
stantial variations of :the magnetostrietive effect, and the feed
magnitude
during each cycle is determined b~r the field intensity of thd-eoil;
2) if
during the opefation of the feed mechanism variable resisting forces
possibly
arise, the variable component of the rated compressive stress of the
rod
Card 3/4 should be less than 0.5 kg/mm2; 3) the magnetizing coil
should ensure a

field intensity in the magnetic circuit of approximately 60 - 80
ampere
turna/cm; 4) in order, to prevent a subatantial thermal elongation of
the
rod, the current density in the coil winding should not exceed 2
amD/mm2.

giving a
push to the servo element M of the machine to 01. The
displacement magni-
tude'depends on the length Lof the rod and the saturation of
magnetic field.
The right clamp closes after the rod is elongatedv and the left
opens and
the coil winding switches off. The rod contracts to initial
length, the
clamps assume zero position, and the cycle repeats. A
nonadjustable radial-
piston hydraulic pump (Fig. 2) controls,the.clamps. It has two
cams in dif-
ferent planes, one controlling two 10 ram'diameter pistons (dl)
and the other
two 12. mn 15istons (d2). -Each dl piston is coupled with a d2,
and the two
piston couples are'at a 451 angle to each other. Each pistons
couple is a
separate pump of 0-5 liter/min capacity at 300 rpm shaft velocity
and con-
trols one clamp. The description includes the control circuit
diagram of
the system, a s'eparate diagram showing the design of the
magnetic switch

ABSTRACT: The authors studied the magmetostriction effects in the
micro-input
mechanisms of metal cutting machine tools. The differential equation
for the
motion of the core of magnetostriction is set up, and it is shown
that tho-calcu-
lations for =gnatostriction mechanisms must take into account the
axial load on
the core and tho dynamic characteristics of the notion. The speed of
response
of the mechanism was obtained and its stability was investigated. The
mechanism
(see Fig. 1 on the Enclosure) consists of a ferromagmetic core (1),
rigidly
coupled to the movable unit (2) and two terminals (3),' Under the
influence of
the magnetic field created by the coil (/+),, the longth L of the
