ABSTRACT: A unit with a magnetic-air operated brake is described for testing a
hirfh- revolution (up to 100, 000-rpra), low-power (up to 4-hp) manual pneumatic
. ol. For convenience in testing different pneumatic tools, the brackets for fasten-
t
0
ing the tool are made to move in grooves, and the tool is braced with flap clamps.
The unit is used for measuring the torque of the tool ignoring the torque of the
pneumatic tool's motor. The rpm of the pneumatic tool's shaft is measured with
the aid of an electromagnetic transducer connected to an ICh-7 frequency meter,
which is connected to the 220-v are circuit. Orig. art. has: 1 figure. [Translation

ABSTRACT: The instrument is intended for the measurement of flow
velocities in the 0-2 m/sec range in wind tunnels. It consists of
a bridge fed by a direct current obtained from an alternating
current via a rectifier. The design parameters of the gage and
the bridge are not adduced. In order to irnprove the accuracy of
the reading in the narrow velocity interval,a null method is used
in conjunction with a galvanometer shunt for senaitivity control.
The hot-wire microanernometer can be employed not only for
visual observations, but likewise for recorded measurements by
means of a mirror galvanometer and a recording drum.

TITLE: Oscillations of Cylindrical Bodies in an Air Flow (Kolebaniya

ABSTRACT: An investigation was performed in a wind tunnel (D = 3m) on the
oscillatory characteristics of cylindrical bodies in a flow of air
directed perpendicularly to the generatrix of the cylinder. Tests
were made under various flow conditions corresponding to impinging
airspeeds from 20 to 60 m/sec with the cylinder supported by an
elastic mounting. The magnitude of the pressure on the cylinder
was registered by means of low-inertia membrane--type transducers
connected to static-pressure orifices, the velocity pulsation in the
stream was measured by a hot-wire anemometer, and the oscil-
lations of the cylinder were measured by a strain gage mounted on
the cylinder; in addition. the oscillations of the cylinder were reg-
Card 1/3 istered by mechanical means. It was determined that in all cases

SOV/124-58-10-10987
Oscillations of Cylindrical Bodies in an Air Flow
the oscillations of the cylinder occur at its natural frequency (dependent on the
degree of elasticity of the mounting) in a plane perpendicular to that of the imping-
ing air flow. This deduction is confirmed by previous observations on the oscil-
lations of smokestacks conducted by the TsNIPS (Central Scientific Research
Institute of Industrial Structures) and also coincides with the deductions of S. P.
Strelkov (Zh. tekhn. fiz. , 1939, Vol 9, Nr 19) regarding the self-excited oscil-
latory character of such a phenomenon. The authors note the inconsistency of
the explanation of the origin of the oscillations of a cylinder in an air flow by the
periodical detachment of Be'nard--KArmAn vortices. The case of wind resonance
is examined, i.e., when the frequency of the detachment of the B6nard-KArmAn
vortices coincides with the natural frequency of the oscillat:ions of the cylinder,
The paper presents oscillograms of the oscillations of a cylinder at various air--
speeds, the magnitude of the drag of the cylinder in relation to the R number, the
relationship between the amplitude of the oscillations of the cylinder and the R
number, and oscillograms of the airspeed pulsations downstream of the cylinder.
Strain-gage recordings, together with recordings of the detachment of the vor-
tices with the cylinder in its extreme positions, are presented. The frequency of
the vortex detachments coincides with the oscillatory frequency of the cylinder.
On the basis of the values obtained, the relaLionship of the normal-force

TEXTs The author analyzes the operation of a diaphragm-type pressure
transducer for measuring fluctuation pressure on a model to which the
transducer is connected by a feedpipe. The purpose of thi's work was to
experimentally derive the correction factors for amplitude and phase
measurements by considering the transducer and its feed duct as a single
vibrating system. Numerous experiments were carried out with transducers
having diaphragms of different size and rigidity and with interconnecting
feedpipes of different diameters. Transducers used were of the strain-
gage type designed by engineer M.N. Vinogradov who also assisted in con-
ductIng the experiments. The results obtained are compiled in 9 grapha

TEXT: Design of a hot-wire anemometer using a thermistor as sensing element
instead of a wire filament is given. The electric anemometer circuit (Fig.
1) is a bridge circuit composed of resistors a, b, and r in the three arms
and a T13 -.8 (TS-8) bead thermistor Rtherm in the fourth arm,. The TS-8
thermistor is shaped like a sphere, 0.2 mm in diameter. Its temperature
response is closely approximated by the exponential curve:
R = Ae B/T P
where R is the thermistor resistance, T is the absolute temperature, and A
and B are constants. The A constant varies for different thermistors while

TEXT: It is shown by theoretical analysis that single-cycle semi-
conductor voltage converters are better than the push-pull convert-
ers in cases when a comparatively high voltage is to be obtained
from a 2.4 - 4.8 volt source. The theory of converters is consider-
ed with forward and backward connected diodes. In converters with
forward connected diodes the limit output power exceeds twice that
of converters with backward diode connections. With low voltage
source supplies (2.4 - 4.8 v) it is better, from energy considera-
tions, to have the transistors in common collector connection, while

ABSTRACT: A telemechanized control system has a number of advantages: objec-
tive monitoring, positive orientation, rapid operation, and substantial reduction
of personnel. Tele,rnechanics at a substation ghould be accompanied by a large-
scale aWomation. Type VRT-53 few-channel supervisory control is considered
in detail. Pew-channel remote-control systems are recommended for indus-
trial electrical supply. Amount of telernechanical devices for a 110/6-10 kv or
154/6-10 kv substation as determined by operating conditions is recommended.
Estimates carried out for a few actual projects show that costs of telemechani-
cal devices are paid in 1-2 years by the savings on the eliminated personnel.

to the difficulties experienced Ln accurately setting up both diodes

ABSTRACT: In an investigation of the temporal characteristics of a GaAs laser the
radiative delay time (T ) was determined as a function of the injection current.
Ordinary diodes ,prepar9d by means 'of the diffusion process, were placed in a dewar
at the liquid N temperature. The laser was excited by a current oscillator with pulse!
amplitudes from 4 to 40 amp and a duration of 40 nanosec. Several diodes were investi-1-
gated at threshold currents frow 1.8 to 4 amp. The dependence Of T on injection
current indicates that the value of T9 approaches 1.8 x 10-9 see. his corresponds
approximately to the spontaneous radiative lifetimes for electrons and holen calculabedl--
theoretically elsewhere (W. P. Dumke, Phys. Rev., 132, 1998, 1963). With a 16-fold

lincrease of Ithr T 9 increases to 0.9 nanosec; this is explained by the time increase
necessary to achieve population inversion. To eliminate delay due to spontaneous
emission and to achieve stimulated emission, the diode was pulsed by currents from an
~auxilliary oscillator with amplitudes of 1.5 Ithr and durations of approximately
1200 nanosec. Some 50 nanosec after the onset of the auxilliary pulse, the diode was
pulsed by a positive current from the master oscillator. The delay time between the
onset of the injection current from the master oscillator and the radiation inducedby
it was measured, and at 17 Ithr was reduced to 6 x 10-11 sec. A further decrease in
T calls for considerably increased injection currents. The experimental data indicate
tRat GaAs lasers can be used as radiation modulators in the centimeter band and as
high-speed (10-10-1011 sec) optical switches. Orig. art. has: 1 figure. IYKI

ABSTRACT: Phenomenological methods were used in an experimental study of certain
properties of GaAs laser diodes (loss factor, quantum yield, differential
efficiency, gain). The specimens were prepared by the diffusion of zinc into n-type
GaAs crystals with electron concentrations of 2 X 1018 cm-3. Une cavities consisted
of silver mirrors sputtered on polished crystalline surfaces pre-coated with a thin
layer of SiO, and the electrical contacts consisted of sputtered metal (Au, Ni, In.
Sn) films and fused-in electrodes. 1.7he measurements were carried out at 77K and the
pulsed output was recorded by a calibrated silicon photodiode. The lowest threshold
currents occurred in diodes which were cleaved on all four sides. A threshold current
of 25 mamp was attained at the liquid He temperature and at a density of 75 amp/cm2.
C-w operation was observed from diodes with I thr < 0.5 amp at 4.2K. The results

inOicate that the transformation of electrical power into optical power occurs with a',
y ;1d of the order of unity and that the greatest loss is due to absorption in the
me ium inside the cavity. The lose coefficient for the better diodes was 5-10 cm-1
at,,77K, a value which had been theoretically predicted elsewhere. The highest
di;fferential efficiency at 77K was 67%, although it was much lower in the case of
diodes with Fabry-Perot cavities under high threshold current densities and in four-
sided diodes with low threshold current densities. The efficiency of the p-n junc-
tions was 0.5-0.55 with a 25Z gain, which took into account losses in series
resistance. Efficiencies of 60% were achieved in the case of optimal re

TECT. One of the most essential deficiencies of correlation receivers is
the necessity of using a multiplier device, the practical realization of which
is rather complicated. The author elucidates the possibility of replacing the
multiplier device by the more simple coherent detector, since the effects of
both these devices are identical by their nature: h-f signals are transformed
into d-c. It is shown that, theoretically, if the frequencies coincide exactly,
such a replacement in the composition of the correlation receiver will only
result in a twofold reduction of the magnitude of the signal-to-noise ratio at
the output. Practically, the noise proofness of the receiver with a coherent
detector will be determined by the frequency instability of the local heterodyne.

ABSTRACT: Because of recent developments in magnetic materials,
electrical machines with permanent-magnet fields are
becoming more widely used. Armature reaction ms
particularly important in such machines but mtthods of
calculating it are very complicated, An experimental
investigation was mada of armaturo reaction in a 250 W,
60 V motor running at 6000 rpm. The motor was
investigated under conditions of reversing and short-..
circuito when the demagnetising effects of armature
reaction are greatest. Three small Hall-effect emitters
were placed in the machine air.-gap under one ofthe pole!e.
Card 1/4 There was one emitter at the middle and two at the edges

of the pole, The circuit used to measure the Hall
effect is shown in Fig 11 recordings were made on an
oscillograph and millivoltmeters. Oncillograms taken
with the rotor locked and 30 V applied to the stator
are drawn in Fig 2. Here curve I represents the
armature current, curve 2 the speed and curves 3, 4 and
5 the Hall emf's from the two pole edges and the middle
of the pole respeotively. It will be seen that with the
rotor locked the induction under the leading edge of the
pole rises by 50 to 60% whilst under the trailing edge
it falls by 80 to 90% and in the middle it is practically
unaltered. An oscillogram obtained during two reversals
of the motor is represented in Fig 32 at the instant when
the armature current reaches its maximum value of
14 times the rated current the induction under the leading
edge of the pole is seen to increase by 150 to 200% and
under the trailing edge it- falls so much that the magnetic
field is reversed. The field at the middle of the pole
Card 2/4 also alters during reversal. During reversals of the

motor, in addition to quadrature armature reaction,
there is the reaction of the temmutating-%:,urrents on
the direct axis, which influences all three emitters.
The large changes in induction under the edges of the
poles during short-circuit, and particularly during
reversal, indica'to that in direct current machines with
permanent magnet fields Khe quadcature armature reaction
has an importanz influence on the magnitude and
distribution of magnetic induction in the air-gap. In
the case of reversal, the reaction of commutating-
currents has an appreciable demagnetising effect which
is superimposed on the demagnetising effect of transverse
armature reaction. This disproves some existing ideas

occurring in the roveraing of a d.c.motor with permanent

machine ahen it is reversed is approached by dividine
the reversion process into three staGes, contrary to
common usage, which employs a division into only two
stages. Trio causes are made responsible for the de-
magnetization: The occurrence of a magnetomotive force

TEXT: The effect of heat treatment on the properties of 60-20-20 type
alloys (60% Cu, 20% Ni, 20% Mn) was determined by measuring the hardness, inter-
nal friction E, electric resistivity and by microstructural and roentgenostrue-
tural analyses. It was found that strengthening depended on ordering (formation
of W-phase, consisting of antiphase domains, separated by deficient layers)
which begins and proceeds near the grain boundaries. The strong effect of
quenching temperature on strengthening after tempering is caus6d by a fine-grained
structure with crushed domains after low-temperature quenching. Plastic deforma-
tion of the alloy after quenching produces fine structure and eliminates the

effect of quenching temperature on strengthening during tempering. The addition
of small B admixtures distributed along the boundaries of grains and domains
retards considerably structural processes entailing strengthening but somewhat
raises 6-' of the alloy and its relaxation stability during heating. Best proper-
ties are obtained after low-temperature quenching from 550 0C and tempering at
4000C (10 hours). As a result of quenching at a heterogeneous fine-grained
structure (solid solution on Cu and 01 phase base) satisfactory ductility is
preserved. Tempering assures hIgh strerkethening. The relaxation stability
during heating and resistance to weak deformation of a 60-20-20 alloy exceed those
of expensive Be-bronze' 6' of the 60-20-20 alloy without B is 78 kg~/=2; with
B it is 86 kg/mm2, 6- of ep.F2 (BrB2) is 80 - 85 kg/mm2; and of Up.62-5 (BrB2.5)
e
it is 80 - 90 . The 60-20-20 alloy can be employed for the manufacture of
various types of spring. There are 26 references.

ABSTRACTL: The size of the do'mains In a finite rectangular parallelepip6d having'
the simple domain structure illUStr.Lted in Fig.1 of the Enclosure is discussed th*0-'
oretically. The surface energy density in a domain wall is assumed to be independent
of tho size of the crystal. The problem thus reduces to that of calculating the en-
ergy of the system in its own demagnetizing field. After a brief discussion of for-
mulas for the demagnot;zatiofi energy previously published for the care in which the
crystal is tinite only in the z direction (see figuro)(C.Kittol,Rov.Mod.Phys.21,541,
