(4) for calculating the working reliability of untrained apparatus is
unsuitable due to the difficult calculation process.' In the author's
opinion, the distribution of disturbances for all N parts of an apparatus.
may be written in the form f(t) - k 1fi(.'-) + k2f2(t) +.k3f3(t), where fi(t)
denotes the distribution density of disturbances due,to production flaws,
f2(t)is the distribution density of disturbances due to breakdo-.Ms,'-and
f3(t) is the distribution density of disturbances due to the aging of parts.

ABSTRACT: Wrobability analysis is used to solve the problem of aging:
of equipment in the case when the parameter describing the ajing can
vary in one direction only (increase or decrease). The problem is
equivalent to determining the integral and differential probability
distribution laws of the time.of faultless operation from the known
characteristic of the random function and the known distribution of
the random quantity of the parameters at one or several values of the
random function. Physically the integral distribution function re-,

gate of realizations, each of which changes in one direction only,
then the procedure for determining the parameters and the probabil-
ity distribution itself can be greatly simplified. A proceduie is
developed for determining the faultless operation time distribution.

ABSTRACT: The author describes a method for the determination of approximate aging times
and substitution times of electronic elements. It is based on the minimization of the lose
function. For certain simple types of distribution (e.g., gamma distribution) the theory yields
reasonably simple equations for the determination of substitution times and aging times which
can be used during reliability determination of electronic equipment. Orig. art. hes: 24

ABSTRACT: This Author Certificate presents a coaxial switch fitted with connectors
mounted in the front part of the switch casing. These connectors are used for
connecting the coaxial lines which are switched. The switch also contains an eleme
connected with the switching mechanism andmith the catchos of the switch operating
positions. The design increases the quality of the connecting contacts. An un-
ground9d section of a nonsymmotrical strip line is used as the switching element.
This ungrounded section rests on the contact disks connected with the central pin
of the connectors. The switching mechanism is fitted with a ring containing a
spring-loadod rod which rents on one of the small balls of the catch. A bushing-is
mounted on the rod and in rigidly connected to the dielectric holder of the switchi.

ABSTRACT: The artir-le deala with inobath scales use3 for the carto-
graphi3al ropr(,iv!nt,'-ti(;a of submarine relief. The
amount of information on geomorphological and geolo6ical
features of submarine relief accumulated in recent
years requires a careful consideration of rie-thods for Map-
ping this relief. The first steps in this direction were
taken by I.P. Zarutskaya itrid V.P. Zenkovich who developed
theoretical questions concerning this cartography. A
scale with ev(~n profile intervals equal for the entire map-
ped territory is best, from the mathematical point of view.
However, due to the K2'eat morpholoi,,ical difference in the
surface r;)lief, it is not used even for larj;e-3cale maps.
Therefore, in practice, such scales are baned on the pre-
liminary investigation of the angles of slope of the p.,irti-
Card 1/2 culer surfaces in regard to the amplitudes of the peaks,

the space occupied by various altitude sthge3 and the
investigation of the pocition and relation of the dif-
ferent types of reliefo. Therefore, for various relief
types, different scales are worked out with an adequate
(-~Iose contour interval for each altitude zone. The article
is accompaniod by illustrations of methods of mapping sub-

ABSTRACT: The authors review the published topographical
maps of the US and find chat these maps have
many defects. As these maps were produced by
different departments, the legends vary, and
many topographic elements are missing. Very
little attention is paid to the mapping of
the soil-vegetative cover. Hydrograi-hical
data are also insufficiently reproduced. If
the soil relief is renroduced meticulously,
the river net is reproduced only schematically.

ABSTRACT: The atlas of Belorusskaya SSR was published in 1958. It has
140 pages, and the edition comprises 15,000 CoPies. It contain.9
8-general and political administration maps, 56 general
geographical maps, 8 physical maps, 48 economic maps,
9 ethnographical maps, and 9 historical maps. The climatic
chart and the map of peat deposits are excellent. The forest
ma-p and goobotanical map are not entirely in agreement with one
another. The fauna map is highly interesting. A scheme of the
economic relations of the Republic with other areas of the 'USSR
Is also given. The characterization of the population is not
exhaustive in the.ethnographical maps. A particular advantage of
the atlas lies in the fact that maps of individual oblast' of
the Republic, namely physical, administrative, and economic
maps of each of the oblast' are also inserted.

ABSTRACT: The meter is designed for the region I - 14 Oe and is

electrons in the measured magnetic field. The accuracy
of the instrument is _+ 0.05%. The instrument is shown
diagrammatically in Figure 1. It consists of 4 plates and
a central cathode. One pair of opposite plates is earthed
and the other is connected to a high-frequency oitillator.
The cathode is at a negative potential (1-3 V) relative
to the platen. It has a by-pass condenser connected
across it as shown In Figure 1. so that it is effectively
AC-earthed. The probe is placed in the measured magnetic
field H so that the latter is perpendicular to the high-
frequency electric field. If the frequency of the
oscillator f feeding the plates is equal to the cyclotron

TITLEt Resonance Instrument for Measuring Intensities of
Magnetic Fields
PERIODICAL:Pribory i tekhnika eksperimenta, 1960, Nr 2,
PP 93-98 (USSR)
ABSTRACT: The principle used is the cyclotron-resonanciof
hydrogen ions in the field to be measured. The intensity
is measured from the difference in frequencies of H+
and H2+ or H2 + and H3 +. The average value of a
field (even containing large non-uniformities) is
measured up to a value of 31500 oersted. The accuracy
is +0-05% and refers to the absolute value. The method
normally employed exploits proton resonance but this
leads to undesirably high frequencies in strong fields.
The use of ionst however, has been objected to since the
cyclotron frequency given by Eq (1) is in practice
subject to a shift caused by the constant radial electric
field within the volume of accelerating ions. To
overcome this objection, the difference in frequencies
Card 1/3 of two different ionic masses is measured. The corrected

form of Eq (1) is Eq (2) and eliminating E(r) when
two kinds of ion are present the magnetic field is
given by Eq (6). For the particular cases of H+, H2*
and H3+ ions the field is given by Eq (7) and (8), in
oersteds, when -the frequency is in Mcls, In addition to
the cyclotron resonance, there is also a polarization
resonance dependent on the ionic concentration. To
avgid error from this Bource, the density is kept below
lo /cm3. The arrangement of the electrodes in the
instrument is Fig 1. An electron beam is directed
through a 4-sided enclosure made up of deflecting plates
connected to two high-frequency oscillators. The other
two sides of the enclosure are accelerating electrodes.
The magnetic field is parallel to the beam. The table
on P 95 gives the optimum gas pressures for different
ions agd enclosure sizes. Measurements were usually made
at 10 mm lig with an enclosure 12 x 12 x 15 mm high.
A block-diagram of the instrument is in Fig 3. The
oscillators cover the range o.665 to 24 ~Ic/s in four
Card 2/3 ranges. A twin-scan display is provided by beam-switching.

Investigations have been made using a magnet whose field
was more stable than 7 x lo-5 and could be varied over
a wide range. Fig 4 and 5 show the variation in
measurement error as a function of beam current and
accelerating voltage respectively. Fig 6 is a similar
curve for collector potential. From these graphs the
optimum operating conditions can be deduced. A useful
application of the device is for stabilizing a magnet

TITLEt An Omegatron with a Nonuniform Magnetic Field
PERIODICAL: Pribory i tekhnika eksperimenta, 1960, No.5, PP-97-99
TEXT: Brubacker and Perkins (Ref-3) have shown that an
omegatron can work in a nonuniform magnetic field. The present
paper investigates the resolving power of an omegatron in a non-
uniform field which falls off along the radius in accordance with
a parabolic law. This type of field is of great practical
importance since it is obtained in a magnet with circular pole-
pieces and plane-parallel gap. An expression is derived for the
resolving power of an omegatron working in such a field and it in
shown that there is no point in increasing the degree of non-
uniformity above 3 or 4% since even though the resolving power
increases,the intensity decreases very strongly. Moreover, experi-
ments showed that the accuracy in the case of a highly nonuniform
field is not very high. The present authors have used a permanent
magnet having a weight of 2.9 kg and a gap of 29 mm. The degree of
non-uniformity was 6.5%. A typical spectrum obtained is shown in

TEXT: Usually, the appearance of resonance in the omegatron is
determined from the position of the maximum of the ion current
at the ion detector. A simpler method is to record the
resonance from the position of the maximum of 'absorbed high-
frequency energy. In this method the ion detector is unnecessary
and the DC amplifier can be replaced by a low-frequency
amplifier. The present authors have used this'method with
the omegatron described by them in Ref. 4. Experiments showed
that the amplitude of the signal depends strongly on the gas
under investigation. For different ion masses there are
different optimum values for the pressure at which the signal
amplitudes are a maximum. Thus, for H + the optimum pressure

is 7 x 10 mm Hg, while for H+ the pressure is

TEXTs For measuring magnetic fields of various configurations
an instrument has been designed, the operation of which is based
on the dependence or the permeability of a magnetodielestric
on the magnetic field potential. It operates in the range of
100 - 8 000 Oe, the accuracy being 0.5%. Compared with an
instrument described by M.P. Zelldovich and S.M. Rubchinskiy
(same Journal, 1958, No.-I, P. 56) this instrument has a more
simple circuit and a morc simple design of the probes, The
calibration oscillator operates at the two fixed frequencies,
760 kc/s and 4 Mc/s. Comparison of the frequencies of the
measuring and calibration oscillators is by means of the zero
beat method. The zero beat is determined by means of the
setting indicator (6E55). The magnetic-field potential
Is determined on tte im o the Vernier of a variable condenser

of the metering oscillator and the calibration curve. The
instrument is calibrated by means of a nuclear instrument.
The measuring device has two interchangeable probes, the
difference being solely in the material of the c;vre coil. The
core of the coil of the first probe is machined from the
t1oxyfer" (1-1000 (P-1000); the second was made of carbonyl
iron (4, W 3.7) . The first probe is suitable for the range
of 100 - 370 Oe. the second for the range of 300 to 8 000 Oe.
The core dimensions are,~ 3 min dia.; 1.5 mm centre hole;
3 nun thick. Coils with 27 turns were wound toroidally on
the cores. The toroidal shape of the windings was chosen
since, in this case, the accuracy of orientation of the probe
in the field does not greatly affect the results of the
measurements. The coil of the probe is connected to the
metering oscillator by a 1.5 m long cable. The probe is
fitted on a perspex rod, 4.,2 mm external diameter, which is
rigidly fixed on the coaxial cable. The instrument indicates

oscilloscope. MsO15 1;s after termination of the pulse, when the
investi--ated discharge is extinguished, the time base is
triZ~;cred aSain and a horizontal line corresponding to 0 probe
current is displayed. The pulse-gonerator is based on 2 vacuum
tubes and 9 thyratrons. The 2 vacuum tubes are double triodes
and are used as anode-Zrid limitors. An RC phase-shift network
is inserted between tho limiter so that its output pulses can be
shifted wit'n respect to each other by 10 - 50 iis. the pulse from
t'a first liniter is a,,lied to the grid of the first thyratron

i-,'!iic?i proCuces a fast pulse at its anode. This pulse ignites
the next thyratron and actuates the supply of the investigated
dischar.ge. The -pulse of the second thyratron has a duration of
about 10 I;s and an anplitude of 140 V and this is applied to the
first Zrid of the third thyratron T 3 ; the second grid of T 3
is also normally at a negative -potential so that T 3 becomes
i3nited only when it receives a pulse from the second limiter.

TITLE; Concentration measurement of charged particles in a strong
high-frequency pulse discharge in a magnetic traveling field
PERIODICAL: Zhurnal tekhnicheskoy fiziki, v, 32., no. 2, 1962. 180-1,84
TEXT: The authors compare the results of measurements of the charged
particle concentration made with strong h-f pulse discharges using data
obtained by the microwave method. The measurements were made with a
cylindrical quartz gas discharge chamber (800 mm long, diameter: 36 mm/"'
The plasma was excited by h-f electromagnetic traveling waves- The
particle concentration was determined with the aid of a double Mo-vire
(I mm in diameter) probe. The voltage drop due to the probe current at a
resistor is fed into an3HO-1 (ENO-1) oscilloscope (Fig. 1) The results
of the measurements made at 1,,10-1 and 6-10'2 mm Hg are in good agreement
with those obtained by the microwave method. Measurements of the distribu-
tion of the electric field made it possible to determine the surplus
charge of the ions caused by the different rates of diffusion of ions and

and the maxiavA amplitude of the magnetic field was 230 Oe. The electroa density
and temperature and the longitudinal component of the high frequency magnetic field
were measured at various distances from the axis to the discharge tube by means of
probes. The electron temperature was 1pyroximately constant at 60 000 OK and the
electron density was of the order of 0 4 CM-3. From the measured data the gradients,
of the plasm& pressure and the magnetic pressure were calculated. The plasma pros-
sure. gradient everywhere exceeded the magnetic; conf lnement of the plasma was so-
cordingiy not achieved. SoMe calculations are presented concerning the behavior at'
;a plasma In a high frequency magnetic field. To achieve confinement It Is not suf-
ifictent simply to increase the magnetic field strength, for the high frequency
f told tends to heat the plasma. It 19 concluded that conf Inement can be achieved
only In an incompletely Ionized plasma withs. large electron density# In which ener-:
