ABSTRACT: It may at-, present be considered to be an establizhed
fact that all
cases of the long-distance propagation of ultra.9hort wave;3 can be
subdivided into two groups, i. t.,thoae with a sporadiec: and
those with
a stable character. It is logi,.al to class the radio waves of the
ultrasbort renge, which are pvpagatcd over long, distance,3 at the
expense of scattering by the local heterogeneities of the iono-
sphers, among the ionospheric %aves. It is, however, also necess-
ary to supplement the present definition of ground waves and to
formulate it precisely. The propagation of ground waves is in-
fluencea to a certain extent by the heterogeneity of the tropo-
sphere, for this heterogeneity causes a distortion of light betams
as well as of radio waves (atmospherlo refraction). The follosd%
definition of ground waves is iadnestW1 Ground vraves are mal.o-
waves which are propagsted over the surface of the earth which is
surrouniea by a normal (standard) atmosphere, and which envelop

ABSTRACT: The statistical properties of the majority of actual
information sources arb characterised by the probability
of occurrence of various information elements, as well as
the probabilities of the existence of the statistical
correlation between successive information elements. If
the information source were characterised only by the
probabilities of the first V I

entropy would be s:Liuple!. This problem is an,-ilysed in
some detail. It is assuned that ail information source
produces a signal whoset spectrum does not exceed a limiting
frequency F . Furthor, it is asiiumed that the reception
is satisfactory, if k levels are distinguished. The

can be terminated by 'k amplitude selectors; each of
these reacts only to specified signal level. Each ampli-

dievice is illustrated in Figure 1. By recording the count

the probabilities of occurrence of various levels:

given by Eq (1) and the rate of transmission of the

is possible to measurc the lantropy of a discrete source.

correlation between successive elements, an approximate
estimate of the entropy can be given by artificially

disadvantage of such a system is due to -the! difficulty

fact thett, ithen the investigated process is governed by

i.e. the carrier frequency is reproduced at the receiver
with a phase delay and a group delay i.e a low frequency
modulation. Thus in the steady staia th; amplitude and
phase of the recelver signal vary with time. The cause
of these variations is the displacement of the dispersing
area. If the dispersirg area remains stable, then the onl .17
form of distortion preEeni; would be a phase shift, depending
on the phase and group tiiae delays. The author then obtains
an expression (Eq 15) for the Doppler frequency shift due to
displacement of the dispersing area. To extend the results
from two ray-paths to a multiplicity of ray-paths, the author
uses the concept of the tropospherio dispersion being equi...

recalling that the first radio-receiving set in

the world was constructed and demonstrated by the

Russian
scientist A.S. Popov in May 1895, and

that later
discoveries, including application of

short waves to TV
Eaid to multi-channel radio coin-

author then refers to the dis-

covery since 1941 of the
curved propagation of ul-

tra short waves, which made TV
reception up to

700 km away a practical proposition. He
descxiibes

how the coherent scattering of radio waves

A Method of Dot ormining the Intensity :f Radio Signals
Reflected From the\'Noon's Surface
PERIODICAL: Radiotekhnikaj 1960, Vol- 15, No. 5, PP. 5-8
TEXT: The main losses of radio signals during their
propagationband re-
flection from the Moon's surface are usually caloulatea from
so-called
"radio-bearing equation'19 assuming that the Moon's surface te
idoall
smooth or ideally diffuse. In the first case (ideally smooth
surfaos~(Refl)
the main losses are determined from formula (1) and in the
fiecond case
(ideally diffuse surface) from formula (2). Observations have
shown
that the Moon's surface is neither ideally smooth nor ideally
diffuse.
Here, it is shown that the same formula (1) may be derived in
another
way by using the method of calculating the intensity of a vave
raflected
from the Earth's surface. These calculations are based on the
following
three principles: 1) The radio wave refleoted from the Earth's
surface

is assumed to be formed within the first Freenel
half-zone; 2) the effect
of the spherical shape of the refloating surface is taken
into siocount;
3) the unevenness of the Earth's awfaae Is taken into
account 'oy a
corresponding reduction of the refLiotion coefficient and
by ita sub-
atitution into the so-oalled "effeclivis reflection
coefficient". Fig. 1
is used to determine the dimensions of the first FreBnel
half-2,one at the
Moon. Formula (3) is written down for the calculation of
!;he radius Of
the first Presnel half-zone at the Moon. Results are
listed in Table 1.
The values obtained show that the dimerisions of the
half-zone aro much
smaller than the Moon's radius throughout the wave range,
The processes
of secondary emission may thus be regarded 8.13 a single
reflection of
radio wavesSfrom the Moon's surface. Next, formula (5) is
written down
for the calculation of the main losses occurring in wave
propaf,,,ation.
For a real, spherical Moon it is necessary tD add the
di,rergence coef-
ficient G to this formula, which considerh the additional
field attenua-
tion of the reflected wave. One obtains formula (6), after
which it is

only necessary to determine 0 to solve the ihole problom.
Fol-mula (12)
is derived for G, substituted into (6), and the definite
formula (13)
is obtained. The latter formula is identical with formula
(1) but offers
a more aocurato physical representattion of the processes
associated with
the reflection of radio waves from the Noonle surface. The
author believes
that the experimental small values ol.' the reflection
coefficient R derived
from reflection, from the Moon's surface can be explained by
tbe additional
reduction of the reflection ooefficiiont, which is caused by
the unevenness
of the Moon's surface. The prooess aissociiated with the
:reflection of
short radio pulses is described next. In the case of pulses
of a duration
of more than orte millisecond, the fundamental reflection is
Superposed
by additional reflections, thus causing an increase in the
intensity of
reflection* It is noted that.this is ob-riously the reason
of the "modula-
tion losses", i.e., the intensity (;f reflection decreases
with an increase
in the duration of the pulse. Thero are 3 figures and !i

PERIODICAL: Radioi 1961, No6 15, pp. 21 - 22
TEXr: The possibility of applying artificial Earth
satellites (AES) its the means of extending the communication
range at ultrashort waves was first indicated (as far as is
known) by Professor P.V. Shmakov on May 27, 1950 at -the
Lecturers' Conference at the Leningradskiy
elektrotekhnicheakiy
institut svyazi (Leningrad Electrotechnical Communications
Institute). At the time, no practical possibilities existed
of arranging such a communications system but the situation
changed on October 4i 1957, when the first Soviet AES,
weighing
83.6 kg, was succoafully launched into space. Two mothods of
using AES for purposes of communications are possible: passive
transmission and radio-relaylnp;. In the first case, an AES Is
in the form of a metallised aphere having a diameter of
several
tons of metres and this acts as a reflector for a powerful

'PURPOSE: This book is intended for scientists and radio
engineers concerned
with the propagation of ultrashort radio waves and with the
equipment used in
this field. It may also be used as a textbook by students in
schools of second-
ary and higher technical education.
COVERAGE: The book deals with presently known inethods of
long-distance com-
munications by means of utilizing some special features of
distant ultrashort-
wave propagation. All of the discussed methods of dElligning
ultrashort-wave
lincs of communication are based on the extensive utilization
of the "divergence-
loss" idea. The recommended methods of design are illustrated
by numerical

examples. The enclosed list of conventional symbols will
assist the reader
in making use of the mathematical presentation of various
phenomena. A
sin cial expression of the power level in relation to a watt
chosen as a refer-
ence level (dbw) has been introduced in the book. The author
thanks N. V.
Osipov for his assistance. There are 40 references: 12
Soviet (including
I translation), 27 English, and 1 French.

PERIODIC.kL: Pribory i tekhnika eksperimenta, na. 5, 1961,
pp. 16o - 161
TEXT: Comoounds based on apoxide resins 3~A-f) (2D-6) and
,400k-7 (ED-7) were used. as vacuum-tight materials in the
development cf a single electrode focusing lens for an ion
source. The evolution of gas from cured speciments was first
assessed by tests in ei vacuum chamber with an inir.ial vacuum
of 5 x 10-7 nun Hg. Without specimens the rate of leakage over
24 hours was 0-03 cc/hour. Two specimens of 1 kg were then
placed
in the chambor; they were made of cured compound basied on
rosins __)-_*5_10(E-37) and :~A-6 (ED-6), polymerised at it
tempera-
ture o'f 150 C for twenty-four hours. The compound.bitsed on
resin
B-37 was loaded with (lust of high-voltage porcelain, ground

give 10% restduo on a numbqr 100 sieve. The filler ii.-i the
compounell based on resin ED-6'was quartz sand, ground. to

residue of 10.5%. The proportions used were epoxide resin
100 partis by 4eight, filler 2!;0 parts by weight, phthaleic
anhydride 30 parts by it-eight. The presence of these samples
dia not -alter the rate of leakage in-to t9e chamber in tests
carried out at a temperature of 18 - 20 C. A single-electrode
focusing lens was then. constructed but the usual ceramic
insulators were completely replaced 'by insulators of e-poxide
compound in.wIlich, however, the filler was reduced to 165
parts
by weight. Particular care was taken to avoid excesi!;ive
heating of the mixture in the early stages of' curing, which
might
have caused cracking. During the course of a year's operation
the lens was periodicakIly heated to a temperature of 80 - 85
0C
and during this time the vacuum dropped to
I x 10-6 nun fig this vras probably due to the preaenco of a
rubber packing between the quartz tube and electrode of the
lens. During this service life there were neither cracks nor
Vr
leakages.

ABSTRACT: This paper describes an accelerator tube of a neutron
made of filled epoxy compound rings, glued together with epoxy
nical and electrical properties of the hardened epoxy compound
described as functions of filler grain size, filler proportion
at equal filler purities, fillers of quartz sand and aluminun
oxide
cal strength which is practically independent of particle ..qize,
filler material. However,, bending strength noticeably increases
particle size and the ratic, of epoxy to filler. The process of
struction is described. In a two-year test operation, with a tube
operated in air, the operating voltage acrons the tube was
maintained
160 kilovolts. At an outside temperature of 20oC., it vacuum of
attained. No leaks were obt-erved during the two yea:rs of

ABSTRACT: The authors discuss the teaching, process and examine
the general theory of ;i
teaching machines. They recommend that the program of a teaching
machine should
explain the concepts studied from many aspects, point out to the
student his mistakes In i
the process of learning, and provide means for cor-recting
mistakes and for the formation
of logical thought. Such requirements are saftisfied, by a
machine whose teaching program
is divided into several branches and which aluo hais a
controlling and correcting program.
Ile program for machines of this type has a deffaiLe structure
whose elements are
specific concepts, the branching system of the program, and the
system for evaluating
the answers. Such machines can be constructed qylte simply on the
basis of a generEd-
purpose digital computer. A relatively simple mochine of uds type
is briefly described.

hydrogen, and helium
gaE.es at pressures between 1.5 and 15 atm. The plasmatrons were
operated continuous-
ly for no more than 15 min due to limiting gas supply. The minimum
currents at which!
they operated stably were 30 and 80 amp for 3-electrode

!JiNSTRACT: The adhesive strength of the claddtng in titanium clad
~tstael produced by vacuum rolling was found to depend upon the
~-rollisg temperature, the reduction, and the ca,rbon content of the
isteel. Tests sho4ed that rolling at 1000-1050C yields the highest
adhesive strength of cladding. A 15-20% reduction in siulle page
rolling ensures strong adhesion which reaches 20-25 kg1mm vLth a
120Z raduction;-further increase to 502 reduction has almost no effect:
ton the adhesive strenth. With a carbon content of 0,028 the adhealwa
;streagth was 26 kg/um ; it dropped to 14 k;/mm:t with carbon content
,of 0,45%. Some alloying elements improve adheoLve strength; in the 1
,case of 0992 stool which had 0,12ZCO the adhesive strength was ants-1
