The use of integral D2187-D304
The paper is concluded with a derivation of an approxima--e formula
for the correction coefficient T. The following model is employed:
Turbulent heat transfer playa a-decisive role in turbuleiit motion
everywhere except for the laminar boundary layer near the wall,
In the la.minar boundary layer,, the most important effect in the
stress transfer is viscous friction, while the most important ef--
fect in the heat transfer is thermal conductivity. It then follows
that the thickness of the hydrodynamic bOUndary layer is different
from the thickness of the thermal boundary layer. In the turbulent
region, the effect of the physical properties of the med:Lum on the
turbulent heat transfer is very small. Subject to varioui3 appro-
ximations, it is shown that

ABSTRACT: The authors investigated the structural changes in the surface
layer of working railroad-car wheel tires (T) and the effect of the
C content (0-45, 0.55, 0.60, 0.68, and 0.86) on the structural
changes in the surface layer of the specinaens when they were
subjected to friction tests - The steel of a worn T containing 0.73%
C and 0.761o Mn has a (Tb of 90kg/mm? - Etching with +16 HN03 Of
samples cut out of various zones of the surface layers of worn T
showed white, etch-resistant layers composed of structurefree
martensite. The formation of such white layers causes a rapidwear
of T. The mechanism of T wear consists of the separation fromthe
rolling surface of particles of plastically deformed metal and of the
Card I /Z white layer, w1iich latter appeared as a result of st:,ructural

transforination caused by friction heat at points of skidding contact. The rate of
development of these processes is explained by insufficient resista.tice of the
metal to plastic deformation, hardenability of the T metal, the occurrence of
skidding, the skidding velocity, and the magnitude of the specific pressures over
the contact surface. ln order to increase wear resistance of T it is necessary
to produce a stronger layer, which would resist breaking down for the longest
possible time, for which purpose the authors recommend use of steels with the
lowest possible C content ( < 0. 6%) and with alloying additives which increase
the strength but do not increase hardenability. The crb should be 95kg/mm2.
The study of structural transformations in the surface layer of laboratory speci-
mens of steels with various C content, friction-tested on a special apparatus,
showed that the nature and properties of T structure in the region of hardened
layer are the same as on the surface of the specimens.

ABSTRACT: The increase in train speeds poses the problem of finding new
materials for brake shoes (B) having high friction properties and
resistance to wear. A test was run on B made at 3 plants from
cast irons having various (up to 1.2%) P contents (with additions
of Fe-P). The coefficient of friction and wear resi.-.tance were
determined by weight loss at different speeds. The results were
analyzed by the correlation process. These laboratc)ry experi-
ments are used to arrive at an iron of optimum composition, sub-
ject to verification by extensive service tests. In '/., this compo-
sition is 2.8-3.2 C, 0.7-1 C combined, 0 7-1 Si, not over 1 2

ABSTRACT: The work reported deals with the possibility of the
detection of ultrahigh frequency signals by means of
reflex klystrons. An experimental investigation wa's
carried out on glass tubes types K-11 and K-26, operating
at wavelengths to X- 10 cm and X - 3 cm. The detection
was achieved by separating the grids of the klyistron
resonators and by applying to them various positive
potentials. This arrangement permitted the obtaining
of various potential distributions in the interaction
space and in the reflector space of the klystrons. The
experimental system employed ii~ illustrated in '.Fig 1,
while its potential distributions are shown in Fig 2.
The detector curves are shown in Fig 3 and 4. Fig 3

.the accelerating grid. Fig 4 ishows similar curves
plotted as a function Of UT which represents thei
difference between the accelerating potential and that
of the second resonator grid. From the curves it is
seen that a detector sensitivity of the order of' 1 A/W
was obtained with the K-11 tuba; this figure is the
same as that of a good crystal detector. There are
4 figures and 1 English reference.

ABSTRACT: The problem was investigated experimentally. The circuit
employed is shown in Fig 1; a constant potential U~
was applied to the accelerating grid and to the firs
grid of the interaction gap; a potential U2 was
applied to the second grid of the interaction gap, and
a potential Uo was injected into the interaction gap.
By adjusting potentials Ul and U2, two virtual
cathodes can be formed inside the tube, as is Illustrated
in Fig 2. The experiments were carried out at wavelengths
of 10 - 3 cm. At the 10 cm i~Tave the UHF power was fed
to the klystron by means of a cavity resonator as shown
in Fig 3a. At the 3 am wave the UHF power wa!; fed by
means of a rectangular waveguide; this is shoim in
Fig 36. The measured results are shown graph'.cally in

the reflector current &10 due to the ultrahigh
frequency signal. The dependence of I and NI on
the gotential of the accelerating grid Ts illustra?ed in
Fig . From the above experiments it is concluded that
the use of the virtual cathodes for the purposE. of the
detection is quite feasible. The best results are
obtained when the virtual cathode effect is very small
The detection mechanism at the 3 cm wave is almost idea_
tical with that at the 10 cm wave. TLe authov, express

TITLE: Travelling wave tubes as UHF'detectors and mixers
PERIODICAL: RadioteRhnika i elektronika, V. 7, no. 5, 1962,
838 - 843
T-IIXT: The purpose of the paper..Is to investigate experimentally the i-I
detector and mixer properties of ordinary low povier travelling wave
tubes in the 10 cm and 3 cm range. The input signal (and the local
oscillator signal in case of mixing) is fed into the travelling 17ave
tube and th 'e detected signal (or i--f signal) is taken from t4e col-
lector-circuit. The voltages on the different electrodes are the sa-
r-e as in amplifier operation except that of the collector which is
considerably depressed. The collector current in the absence of in-
put signal depends very strongly on collector voltage. The collec-
tor current in the presence of signal is altered. The current dif-
ference, A I k and its ratio to input power, Llk/Pc, are plotted

against input power. For small input power (P c-< 5p.W) the detector
characteristics are near to quadratic. The minimum detectable signal
wasJbund to be about 10-10 watt which is of the same order as that
obtainable by a TVIT-crystal combination. In mixer operation the cho-
sen _J-f frequency was 40 Mo. The dependence of conver.sion gain and
i-f Dower on input power is plotted, showing about 17 db conversion
gain in low level operation. I-f power plotted against local oscil-
lator power shows a maximum around P10 Str' 50 - 70 microwatts. The li-
mit sensitivity of the travelling wave tube mixer was found to be
worse than that of the TVIT-crystal by 5 'to 10 db. The bandividth of
the mixer was not determined but in each case it exceeded '10 %. Some
experiments were also performed by feeding back the higher frequency
to the input of the travelling wave tube. The limiting sensitivity
imnroved in this case 'by approximately 3 db. There are 6 figures.
