TITIZ, : Probability of signal locking by a phase-lack AFC frequency- search system
SOURCE: IVUZ. Radiotekhnika, v. 8, no. 6, 1965, 696-703
TOPIC TAGS: AFC, signal frequency. frequency locking
ABSTRACT: The operation of a phase-lock AFC system an a narrow-band tracking
filter is theoretically analyzed; an active proportional-integrating filter is used as a
low--wpass filter, (after the phase detector) in this AFC system. The time of frequency
search in limited; hence, the search is Assumed to be fast. With a high search
speed, the signal locking may fail to materialize due to the low-pass filter inertia.
The probability of signal locking by the above AFC system, under no-noise
conditions, is determined; this permits determining maidmurn frequency-search
speed (a formula is developed) which still ensures locking. under noise conditions.
this speed will a-priori be lower. It is proven that with higher search speeds, the

probability of locking falls off rather slowly; beyand a certain point, however, the
probability drops abruptly, the latter effect being more pronounced for higher
attenuations. It iff also found that setting the attenuation t > I cannot result in aL
substantial increase of the locking probability under no-noise conditions. Orig. art.

ABSTRACT: The exis".rig methoi of mrnitoring garrima-adiation doses by
biackenir.g of a p~L-toillm Kas disadvantages due to the following factors:
(1) measuremert regii't-3 depend on the rad-;ation energy*, (Z) sensitivity is low;
(3) measurement of the degree of blacken,.ng by a dersitcmeter is subjective.
Steps to overcome the above disadvantages are considered. The photofilm is
most sensitive to soft gamma rad.ilaticn. To compensate for this, filters are
used that co-rnpr;ee a layer of lead arA a layer of aluminum. Lead ensures

Improved Method for Personal 13,hotomonitoring of Gamma Hazard (IFK-11)
greater absorption,of soft gamma radiation, while aluminum protects the
emulsion against the secondary electrons knocked out of lead by gamma quanta.
To increase the sensitivity, the compensating filters are used in combination
with intensifying screens prepared from calcium tungstate. The optimum
thickness of a lead filter with an intensifying screen is 1. 5-1.6 mm; without
the screen, 0.75-0. 8 mm. The thickness of the aluminum layer is 0. 5 mm.
A c ompensation -type photometric scheme with selenium phototubes has been
used for objective evaluation of blackening.

ABSTRACT: In the procedure reconimended two spline grooves
are simultaneously roughed out in each of the two
shafts mounted side by side by means of form cutters.
Carbide-tipped face cutters are used to finish the
spline flanks. Their interspace is adjusted against
Belleville springs. Five roughing methods are com-
pared under different conditions, each followed by
a finishing operation. The machining time and total
piece-work time is given in each case. The highest

time by 2 to 15 times. The use of carbide-tipped
finishing cutters increasps accuracy without requiring

TITLE: The Coefficient * for Calculation of Hardness of
Reinforced Concrete Elements. (0 koeffitsiyente

PERIODICAL: Beton i Zhelezobeton, 1958 Nr 2, pp '06-69.
ABSTRACT: CalcijlRtion of the strength of the ab-)ve-mentioned
problem uses coefficient'V according to the theory
of Professor V.I. Murashev? accepted by the standnrds
(NiTU 123-55). This coefficient is the function of
the concrete in the tension zone in between cracks,
i.e. changes of tensions in the reinforcement of the
concrete with load variation. A theoretical ex-
planation of the function of this coefficient and its
application is given in detail. Figure 1 illustrates
a curve of distribution of tensions and moments in
inforcement and concrete of the tensioned zone of the
reinforced concrete unit in between cracks. Figure 2
shows diagrams of various + coefficient-,for bent
