VITLE: A noitte-free ship tachometer ~Q
3OURCE: Sudontroyeniye, no. 4, 1966, 28-30
COPIC TAGS: marine equipment, tachometer
UWRACT: The authors deiieribe a tachometer developed at the "Vibrator" plant which
5atisfies the reliability and noise level requirements for ship operation. The tacho-
aeter uses a special electric machine with an arc stator and a rotor which is fixed to
;he shaft. TUe stator is fixed next to the shaft at a given distance from the rotor.
Phe rotor does not have any kind of electric contacts or windings but; is equipped
.rith permanent magnets. The measured rotation of the shaft is transformed by a three-
.)hase synchronous generator into a-c whose frequency is directly proportional to the
aeasured rate of rotation. An expression for this is given. Thus as the rotor mounte
)n a shaft turns, three-phase a-c voltage is generated in the stator windings which is
red in turn to synchronouv electric Indicators. Diagrams and specifications for the
mit are given. This tachometer satisfies all requirements and is tte finest instru-
ment of its kind. Orig. ext. has: 5 figures, 2 tables, 6 formulas.

ABSTRACT: Production Une reliabilit is defined in terms of volume, quality, and rate
of ouiput. These properties are assessed in application to each unit position in the
.line, to the totality of units, and to the line as a whole. Three aspects of reliabi-
:lity am distinguished: a) extensive reliability, defined by the reliability of the
~operation of equipment; b) intensive reliability, defined by the stability of output

Title : Experimental study of certain physical properties of
alloy steels
Periodical : Teploenergetika,2, 3, 3-10, Mr 1955
Abstract : The author studies the behavior of alloy and high-alloy
steels under conditions of high and super-high steam
characteristics In modern high temperature and high-
pressure boilers. He studies thermal expansion and
eleetric-and heat-conductivity of: austenitic steels

Steels
PERIODICAL: Teploenergetillm, 1959, Nr 91 PP 79-83 (US3R)
ABSTRACT: The influence of heat treatment on the thermal
,_,onduotivity, -3lectrical resistance and Lorenz number of
(.-arbon steels in the annealed and hardened conditions was
studied over the temperature range 20 - 900 OC for six
grades of steel. The influence of annealing temperature
was studied on two grades of slueel; they were als,-, studied
after normalisZCI-ion. The chemical compositi~,ris of the
Steels used and their heat treatment ccndit-*Lons are
tabitlated. Graphs of eiectrical resistance and thermal
conductivity as functinns of ~einperature are pictted in
Figs 1-6. The results show that the physical properties
of hardened and. annealed steels depend mainly on the
temperuture and. very little on time when the specimens
are held at cr:n3tant temperature for to 3 hours. The

hardened condition differ by 10 - 15% from those of the steels
given a tempering treatment; this difference persists up to
100 OC; it decreases with increasing temperature and et 500 0 C
amounts to 2-3ou only; c) as the total alloying-elements
content of the steel increases its electrical-resisti-ity afid
Lorenz number increase and the heat-conductivity decreases. The
difference between the values of these properties for steels of
various compositions decreases with increasing temperature.

values agree within 5% with the author's formula for hardened and
aged specimens; the coefficients are lower for deformed specimens
and are represented by the dashed-line curve. Density measure-
ments confirm that steels containing elements with higher atomic
radii have a higher density. 0The steel EI851 (2% W) has the
hignest density, 8.116 at 20 C; steel EI850 (containing 4% 51)
has the lowest density,'7.732. Ageing and deformation have only
an insignificant influence on the density.

an electric drive which closes the valve in the pipeline through which
the hydrolyeate flows into the neutralizer. A diagram of the instru-

for digital recording of geophysical data. It is shown that fixing the signal lev-
el throughout the time of conversion is the optimum method for reducing errors due
to the rate of change in the signal being converted at a given converter speed.
The level of the input signal may be fixed by various methods based an gating and
storage in capacitors. All these methods require rapid switching elements such as
transistors and vacuun tubes. However, these switches are not applicable in wide

ranges and are insensitive to small currents and voltages. It is shown that delay
lines may be used for reducing the requirements for rapid switching. A circuit is
proposed for a converter which uses a delay line as a storage element. This ccn-
verter operates on a considerably wider frequency band for the input signal while
maintaining the speed and accuracy of conversion which is equivalent to Increasing
the speed of the converter. Orig. art. has: 1 figure, 1 formula.
