case of slowly changing motions, or the absence of centrifugal
forces. In actual practice, there are frequently caties, where a
flow, passing tbru some structure, is deformed to such an extent
that the model of a slowly changing motion may no longer be used.
Centrifugal forces will appear, which are expressed in the afore-
mentioned equation by dh,, thus - dz - dh v * A f * dh i * (2)
The presence of the magn,'* ;e dhi complicetes the integration of
the equation to a consideraole extent. There are at-tempts in solv-
ing this problem theoretically, for example G.I. Sukhomel (R~f.S),
however, no results for practical use have been obtained. Taking
into consideration the difficulty of solving this problem by theo--
retical methods, the author attempted to solve experimentally the
case of a high-speed flow in a rectangular cross-section. These
investigations dealt with s a) the determination of the degree of
flow deformations in the cross-section of the model, depending on
the compression of the flow upon entering; b) studies of generallv
known integrals of the equation (1) concerning their use in cal-

The Problem of Calculating High-Speed rlove of Rectangular Cross-Section
cies for calculating the depths in the cross-section. The investi-
gations were performed at the Novocherkasak Institute of Meliora-
tion Rngineering during 1957 and 1958 under the guidance of Can-
didate of Technical Sciences, Docent U.N. 3kiba. A model of a
high-speed Ylov was built especially for theme investigations.
Its plan in shown in fig.4. The dimensions of the model are list-
ed. According to the method of Professor A.P. Beresiaskiy (Ref.3),
only one half of the flow was investigated. The results of these
investigations were compiled in seven sets of graphs. Deviations
of theoretical values from experimental data are given in percen-
tages. Using formulas of M.M. Skiba, I.I. Agroskin and Bussinska-
Bakhmetev, the author derives a calculation method for the curves
of a free surface in high-speed flown of rectangular profile. Ex-
perimental data of A.P. logthda (Ref.5) are mentioned in this con-
nection. This paper was presented by the Kafedra gidravliki
(MAir of Hydraulics). There are 2 diagrams, 7 sets of graphs
Card 3/4 2 tables and 10 Soviet references. ~K

which however, make further tests nceessary. Tne
author feeis that the throughlut capacity of a slii~_
way is Influcncec by the following lact(.rs: a) 1he
degree oi lateral compression; b) '.he proportional
width of the spillway; c) The slope factor of the

of the Si 28 C1 35, and 21 bands of the isotopic molectiles, were
identified and tabulated, reducing the wavelength in air to wave-
numbers in vacuum by means of the Kayser tables. Tile extensive
transverse v' = 2 series and the bands (3,1), (4,1) and (.).2)
yielded much higher accuracy in the determination of the
vibrational constant of the upper excited state B2 E and also
served as a cross-check.

ABSTRACT: A method is proposed for measuring the poteitial of a
plasma du~ring the time of flight of a beam of charged particles
through the plasma. In the case of a dense plasma, w).en the Deby"-
screening radius is small and the electric fields in the plasma are
concentrated in a narrow boundary layer, methods using beam& of

charge particles entail experimental difficulties. The operation of
the experimental setup is such that after the injection pulse is
Icompleted, the potential of the grid of the plasma gun becoires
lower than the cathode potential, and the electrons are locked in a
trap. The plasma is produced as a result of ionization of the re-
sidual gas by the electrons. 7he potential well is measured by
passing a modulated beam of krypton ions through the plasma. The
time dependence of the plasma potential in determined from oscillo-
grams which slow the phase shift of the ions in the beam. Orig.

R is the radius of the region occupied by the plasma. This relationship may be used
to establish the energy distribution of the stream of ions circulating in the trap
from the distribution of neutral ions. By narrowing the time interval for registra-
tion of the recharged particles, the variation in the intensity of a strean of ioniz-
ed atoms of a given energy may be plotted an a function of time, which means that the
same may be done for the intensity of ions of a given energy in the trap. It is shc
'that there is a hot plan with an average ion energy of the order of 400 ev in an
electromagnetic trep,, %ban the Injected electrons have an energy of the order of 2 kev.
The decay time after the Injection pulse Is 50-00 psoc which ogre*& with the previous-
ly measured lifetime for hot electrons in this trap. A cAmparison of the lifetimes

pp. 21 - 27
TFMi The paper analyzes the operation and gives the design of selective
and directional power filter units for protective relaying of two-phase ground
faults occurring at various spots in the system with an isolated, or compensated
neutral. The filter units disconnect one faulty line and preserve the operatlon
of the other one. They were built and tested in the laboratory o~ protective
relaying and automation of power systems of the Moskovskiy energeticheakly In-
stitut (Moscow Power Engineering Institute). The selective filter unit conElsts
of two three-phase voltage filters - forward and reverse sequence - a voltage
amplitude-equalizing circuit, an adding circuit, and a three-phase phase-senst-
tive circuit. The selective filter unit operates at ground faults with A and C
phases only. It can directly be connected Into contactless transistor protectjw
circuits, e.g.: a high-frequency phase-difference protective circuit Also, a
sensitive zero Indicator can be connected to the output of the phase-sensitive

circuit. The directional power filter unit consists of a single-phase reverse-
sequence voltage filter, a three-phase forwarJ-sequence filter, a voltage ampli-
tude-equalizing circuit, an adder circuit, a frequency filter, a phase-sensItive
circuit and a transformer. It Is advisable to use a transistor transducer of the
Hall emf (Ref. 9) in place of the phase-sensitive circuit with electric additicti.
By using the transducer as a harmonic analyzer (Ref. 10), the frequency filter
caLn also be omitted. Tnere are 4 figures and 10 Soviet references.

certain details of phenomena takint place in one of the types
of specimens with e "vacancy source", namely, in specimens
of an alloy from which the volatile component is rcmoved.
The selection was governed by the desire to fo.,low simultan-
eously the kinetics of the coaGulation of the excess vace.Lcies
and the kinetics of their removal from the specimen waich can
be materialised most easily on specimens of an alloy which
does contain a volatile component. Brass containine, 30* zinc
was used for the investi6etioris in the form cf 20 um 1o%,
4 mm. dia. cylindrical specimens after preliminz-ry stabilisaticn
by annea-ing at 820 C. The time and temperature depcadence
out 2/2 of the decrease in viei&nt and volume of' a-bras3 specimens
was followed experimentally after removillL L11(- VOI-Eltile
component, i.e. the zinc. On the basis of Loe obtaixieu
