institut (Leningrad Polytechnical Inctit-ute). The results
obtained and the r!-.Gults advanced in this paper demonstrated
that a shielding of iron cores by copper shields in in-
atallations as described here is very effective. A shielding
of iron cores is particularly expedient for high frequency.
The experiments carried out substantiated the correctness
of the method advanced in thio paper of the electromagnetic
calculation of apparatus, vihich are similar to the electro-
dynamical vibration test stand 4,ind which are equipped ritb a

TITLE: Sensitive discriminator with external control
SOURCE: Pribory i tekhnika eksperimenta no. 4, 1965, IU-114
TOPIC TAGS: discriminator,, transistorized circuit
ABSTRACT: The basic circuit for a sensitive discriminator (threshold,
10-3-10-1 v) wi th external control is described (see Fig. I of the Enclosure).
Its application in radiometrio devices appears promising; amplification of the
output signal from a nuclear emission detector is unneceseary. The distingguishing
feature of the circuit is that after triggering it does not recover its sensi-
tivity independently but is forced to return to the initial state by,external con-
trolling pulses. The stable state of the circuit is obtained by the introduction
of an additional negative feedback loop through a diode (D ), so that the total
gain in* the feedback .'loop is 146"es - than.-i 1.~ - Afin andlyeid of the circuit
senpItivity and'a calculation of the thermal stability of the-discriminator
threshold' are presented..-. Component parameters are given for the circuit as

=RACT: Based on a generalization of experimental material, a series of
deductions are made relative to the structure and properties of alloys of the
quasibinary ZnSb-CdSb system. A phase diagram of -this system, constructed
on the basis of data from thermal, x-ray, and microstructural investigations and
from measurements of density ?and microhardness, represents a continuous series
of solid solutions. The crystallographic group, configuration of the short range
order and thetype of chemical bonds in the solid solutions are the same as in
binary'components. It is noted, that besides the stable ZnSb~-CdSb system, there
also exists a metastable, tempez:ature position of the liquidus and the solidus,

which is different from that in the stable system. The study of such electro-
phydical properties as electroconductivity, thermal electromotive force, heat
conduction carrier mobility, and carrier activation energy has shown the
presence of the e)ftremum of these properties in the ZnCdSb4alloy. Although
x-rays do not shoii this alloy to have any structural peculiatities, the authors
suggest that it should be considered as a ternary chemico compound, w%th
calculated lensth of bonds: Zn-Cd 2.93 A; Sb-Sb 2.81 A; Zn-Sb 2.65 A;
Cd-Sb 2. 81 A. A bibliography with 93 references is included. 1. Marchukova.

ABSTRACT: This is an experimental investigation of the convective heat trans-
fer and drag for the flow of hot air in the initial section of a circular
tube. The inlet-flow temperature was varied in the range of from 200
to 5000C and the tube-wall temperature was maintained constant at
1000C all along the length of the tube: the inlet into the tube was s'harp-
edged, the inside surface of the tube was technically smooth, and the
relative length of the tube was equal to approximately 40 inside dia-
meters, Experimental values of the drag coefficient and profiles of
velocities and temperatures are given for isothermal and noniso-
-thermal flow of air as well as the relationship of the Nusselt number

the conditions of the experiment the flow developed into turbulence even at values
of Reynolds number less than 10,000. Under conditiops of nonisothermal flow of
air the length of the initial hydrodynamic sector did not exceed 20 inside diameters,
and the length of initial thermal sector was within the limits of 10- 16 cliameter:3,
depending upon the value of Reynolds number. Data were obtained for determining
the mean heat-transfer coefficient on the initial sector for different values of the
Reynolds number and inlet air temperatures in connection with the design calcula-
tion of a short-tube heat exchanger.

ABSTRACT: Samples of alloys of the ZnSb-CdSb system in 5 mol-%'concentration,
increments from 0 to 100 mol% CdSb were subjected to x-ray analysib. It was
found that all of the alloys are rhombic which led to*the assumption of that
the alloys are a continuous series of solid solutions. All the x-raj powder
diagrams indicate no struatural peculiarities among the alloys. Values of all'
three structural parameters increased with increase in CdSb content. A deviation
from Vegard's law was observed in the 5q mo1% CdSb range indicating the formation
of an ordered solid solution or chemical compound* However if a chemical cccpound'~,

interchangeability of the Zu and Me As a result of the analgous, initial

ABSTRACT: The problem is a special case of the general problem of the
calculation of the forced vibrations of elastic systems having
many degrees of freedom including hysteresis losses [Sorokin,
Ye. S. , Issledovaniya po dinamike sooruzheniy (Investigations
on the Dynamics of Structures). Stroyizdat, 1951; Pisarenko,
G. S. , Kolebaniya uprugihkh sistem s uchetom rasseyaniya
energii v materiale (Vibrations of Elastic Systems With Due
Account for the Energy Dissipation Within the Material).
Kiyev, lzd-vo AN UkrSSR, 1955]. The solution of the equa-
tion of the vibrations is performed by the matrix method. It
:s concluded that the rate of decay of the vibrations is deter-
mined only by the diagonal -terms of the dissipation matrix

ABSTRACT: During 1962-1963j five blow6r-type sprayers (OPV, OVT-10
OVS-2, OSS, ONKh) and one hydraulic hose aprayer (OF-10) developed by
the L'vov State Special Construction Bureau for Machinery for Chemical
Plant Protection, were tested at the.Pushkin, Severo-Kavkaz, and
Moldavian Machine Inspection Stations. Using standard'yeathods, the
machinery was inspected during treatment of fruit and berry crops with
a spray containing 0*15Z Paris green, 1% Bordeaux mixture, 0.7% DDT9
and O*lZ parathions Drivers of the tractors hauling these sprayers-

ABSTRACT: Tho rate ot formation of

hexoses in aqueous solutions of inorganic acids depends upon the
reaction conditions and upon the nature of the monosaacharide
being decomposed* in was shown that,among'the pentoses D-erythro-v
is dehydrated in aqueous solutions of sulfurie acid
much faster than D-arabinose, or D-ribose. On the basis of

by.lqs (12). Bach of-th.elooefficients 81 and 82 can
be expressed as a sum of-two components, as shown in
]Cqs (14). These in turn, can be expressed by Bqa (15)
and (16)0 The first cozponents of Zqs (14) can also be
represented in the form of Bqs (19). Now, the diffracted
-field components can be determined on the basis of the
geometrical optics apprckimation and are in the form of
Eke (20). These shosAld be corrected by employing the first
components of the.coeffItients 8 and 8 and it is

shown that the oorreotic~ns are expressed by lqs' (24), where
W1 and W2 are Airy functions.- The corrections can.

When 6=IV, an approxinate solution can be obtained by
employing the vector-potential method. For the purpose
of this calculation, it is assumed that the co-ordinates
at the surface of the sphere are iL, e , -and vi while

The field components are-shown to be in the form of
Eqs (40), where :e, ani a,, are expressed by.Eqs (41)..
These functions can also be represented by Eqs (48) or,
,finally, b_v Eqs (52). The -above analytical formulae were
employed to plot the graphs of-the functions e and e
and these are shown in Figures 4,, 5, 6, 7. Curves
designated by 1 are evaluated by using the accurate
formulae (see Eqs (2) ), curves denoted by 2 are evaluatilt
.by Eqs (52), while Cur'ires 3 are calculated by using the
geometrical-optical approximation and the corrections-as
defined by Eq (34). F com the graphs, it is seen that, in
general, the approximation formulae are sufficiently
accur ate,-. The-author expresses his gratitude to
L. A. Vaynshieyn.,for Urecting this work.
