ABSTRACT: It is a iuo-,,t iaportant problem to extend 11-he range oi heads
for ivhich Kaplan turbines can be used. This is mainly a
question of the development of new types and desir, s of high
;n
head Kaplan rum-iers. In the U.S.S.R., Kaplan turbines are
already opei-ating on heads of -30 - 32 metres. Abroad heads
of 54 metres, 56 metres and 63.5 metres are used. it is
necessary quickly to increase the head at which Kaplan turbines
can be used to 50 - 70 metres.
One of the main technical diffi,~ulties in the application
of .~i6h head Kaplan turbines is the necessity of sinking them
to a gi-eat,ur dcpth than radial-axial turbines. However, depth
is not alaays the iia-iting factor as in anderground stations
or when t 4u s-6~-Lion is a1onL;_--ide the dam. Nev,_-rtheless, i-G Ls
very imDo.,;ant to 4-,.;rove the cavitation ch.--racteristics of
the runners. 'The ratio of the hub diameter to the runner
diameter i.-; impoitant in improviniS cavitation properties. Hub
diameter hE-.-,: mainly b.,;en governed by the ,jize of tl..--~ blade
rotating mQchanism enclosed within it. It' the hub ratio is

Kaplan runners it would be necess,-,i-y to select a hub j--xtio
that results in a reduction of speed and impaired cavitation
prope.Lties of the runner. Althouja for high head ru-,iners an
increase in liub dimension is unavoidable one metho('- of
irdprovinj. L1,- :.avitatio- pi-ojjcrti~!s is to make the hub as
small as pos;jible. IL is, therefoce, necesLQir~y to re-de-,--i6m

mechanism without increasin6 the hub diameter. One method of

axial direction. DiaSrams of liAsible mechanisms for doing
this are given. Formulae are iven fo:-- the to--.,-que or. the

It will be seen that in the initial period of
retardation the actual resultant retarding T,--.Yqu,- -is
greater than that determined from the static
characteristics whilst at low speeds it is less. The
very high transient ter-ques that are observed under
certain conditions ma:, damage the motor or the machines
connected to it. Rapid changes in the rate Of rotation
are possible when the motor is running light and help
it to absorb these oscillating torques which would be
greater in the presence of addi.,~icnal iffect.
Examination of a large number of oscill-)grams taken
during the tests confirms th~it it is pLssible to obtain
mean universal dynamic characteristics for motors of a
given synchronous speed.. It would be Avery LMpC1t,1r171" to
obtain such characteristics for a solution of

ABSTRACT: The author discusses the precision of a triangulation performed wi*,J,-, a
radio-controlled theodolite and parachuted sight targets. The crosshairs of the theo-
dolites are kept on the floating target by means of two thlxrb screws. At a radio Sig-
'nal from the plane, photographs are taken against the background of the
climb of the theodolite to show some object on the ground and the floating target. 7' ne
following should be complied with to maintain the necessary precision: a) all shutters
should be synchronized within 20.2; b) for a velocity of the moving target of .3 m/sec
,:and a distance of 50 km, the expovure time should not exceed 0.04 sec. To weignt the
observations of the ground object :!nd of the moving target, the number of observations
of the target should be 2 (m,'+

Magnetic Recording of ftlses (0 rpagnitnoy zapisi impill'sov)
PERIODICAL: Priborostroyeniye, 1959, h1r 5, pp 1244 (USSR)
ABSTRACT% It is convenient to use the nonlinearity of the characteristic of
the magnetizatinn of the carrier for the magnetio recording of
pulses with a constant amplitude. The process of recording with
the u5s oi tibia phenomenon can be termed *recording from saturation
into saturation". It is based on the followingi the recarding
element causes a constantly acting magnetic fiAld Which leads the
carrier into saturation independently of the pi:-Vious rogmetic
state. For the recording of the pulse and for the determination
of the corresponding magnetic indentation, an additional current
pulse of a certain shape and amplitude is produosd in -the
recording head, which is sufficient for tU tagnetio reversa2 of
the carrier unti'.. saturation with the opposite sigr, is attained.
For recoiding the pulses "from saturation into P-iturmdon" a
graphic method is used, by which the shape of T.,,gaetic indentation
and of the reproduced emf can be determined as a function of the
current pulse, of the parameters of the carrier wid of the
Card 11/2 "recording heads", as well as of the magnetizing .rooess. The

XWetic Reoordjng of Pulses
SOV/1-19-59-5-7/22
theoretical basis of this graphic method, i.e. the equations for
the processes during recording and reproducing, are indicated, and
the resulting calculations are demonstrated step by step. Jklso the
graphic construction is carried out step by step. The following
conclusions are madet 1) For the record.Ing "from saturation into
saturation", there is no need for a preliminary treatment of the
carrier, or for a high-frequenoy shifting of the linearization of
the function BrCH. B r designates the remanent induction. 2) The
recording "from saturation into saturation" facilitates the
formation of the "peak" of magnetic indentation, as well as the
reduction of the influence of Oyu-1sation*, and of the irregularity
in thickness of the parrier, on the stability of recording. To
reduce the width of the resulting indentatic)n, and to increase the
density of recording, "magmetio hebds"-,#ith a heavy drop of field
strength behind the gap must be used. Thus, It is principally
poasible to obtain Indentations which are narrower than the gap.
The circuit diWams of these recording heads are given. The
wirings discuased here worked satisfactorily, they ensured a
reliable recording of pulses. There are 2 figures and 2 Soviet

TITLE: Two Circuits With Application of a Phantastron
PERIODICAL: Priborostroyeniye, 1959, Nr 9, p 26 (USSR)
ABSTRACT: The first part of the paper deals with the phantastron as
generator of slave sweep. Thn generator 'or a linearly
decreasing voltage, which constitutes an inseparable feature of
the phantastron circuit, is appropriately used as generator of a
periodic slave sweep (razvertka) in electronic oscillographs.
Some of the great advantages of this generator are the high
degree of linearity of the serrated voltage, the wide range of
frequencies producible, the large amplitude of the output
voltage, simple modification of operating mode, synchronization,
starting of the genGrator, etc. The first figure shovis a circuit
which may be used as generator of a continuous or pe:,iodi -c slave
sweep. Details and operating mode are discussed briefly. Under
conditions de-cribed here the generator produces a linearly
decreasing vo.~-;age of up to 200 v (from Deak to peak) with

les. The upper boundary
ranging from 15 to 5,000 cYn
Card 1/2 of these frequencies was raised considerably by certain

Two Circuits With Application of a Phantastron SJV/1 i 9-r-19-9-1 3/1 9
measures described in the present paper. This circuit requires
next to no tuning, since the operating mode depends but little
on the voltage of the supply current. The second part of the
paper describes the application of the phantastron as convenient
trigger circuit, which produces practically rectangular positive
pulses of variable duration and different "porosity"(frequency).
A circuit of this type is illustrated in a figure. The stability
of the pulse durati6n and the value of the "porosity" are very
much higher for the phantastron than for the absorptive multi-
vibrators having a stable position used for the same purpcse.
'Under conditions described here the phantastron produces
rectangular pulses with 150 v amplitudes and a duraticn of 100 to
7 msecs. The duration of pulses can be decreased remarkably by
reducing the capacitance C. The instability of the duration is
very low, and does not exceed 0-5% even for the longest pulse.
Fluctuations of the supply current are hardly noticeable in the
measurements. This circuit requires practically no tuning, but
consists of approximately as Diany parts as any multivibrator.
There are 2 figuree.

The solution o1 reconnaissance problems is guaranteed by either 5---

ses by 2-milligal surveying; in most areas, however, they are solved
by milligal, half-milligal and more detailed surveys. The task fop-'
1959-1965 is to expand in every possible way half- and quarter-
milligal surveys. The factory production of two types of quartz

"E,pidemioliogy of Infectious Hepatitis in the People's Anny"
Sofia, Voenno D.Leditsinsko Delo, Vol 21, No 1, _Peb 66, pp 51-56
Abstract: The epidei-.-,:o1ogy of i-rifectiouz; hepatitis in th.e 'Buigar-
inn army in 1953-1~b4 was studied. ),iring this -,)eriod there was a
silghtly rising trend in the incidence of infectious hepatitis in
the Bulgarian araky and in -i-lulgaria in general. The study indicated
that individual cases of the disease among militar~y personnel,
which ware more f:equent than th-ose associated with localized out-
breaks ih the a:nay, were due primarily to contacts with the civil-
ian population. Investigation of sanitary conditions in detach-
ments in which epidemic outhreaks occwxed led to the conclusion
that the principal inechanicm ef transmission was intestinal. Th a
outbreaks generally occurrod in the swwner months, when intestinal
diseases were prevalent. In some detachments, occurrence of infec-
tious hepatitis preceded or accompanied outbreaks uf dysenter~y.
There were no indications that infectious hepatitis in the army
was transmjJted by the air droplet mechanism or by inoculation into
the blood stream. Tables and graphs, 16 references(4 Bulgarian,
2 Western). Russian summary.
