ABSTRACT: The amount of the scrap and luppen in blast furnace charges will decrease
in the future. It will be necessary to determine the minimum iron content required
in a charge, the required amount of slag, and of coke. The charge will require
agglomeration, and better grade ores will have to be imported. An amount of 200-300
kg of slag per ton of pig iron is enough. The content of S under these conditions
should be between 0.025 and 0.035%. The content of Mn should also be reduced.
0.1-0.2% Mn at CaO/SiO2 ratios of 0.95 to 1 is satisfactory. The content of Mn
is a function of the S and C content in the pig iron. Orig. art. has: 5 figures,
6 formulas and 6 tables. 1JPRS: 36,6461

Abstract It was found that the most effective means for sterili-
zing the injection emulsion of estradiol benzoate, stabi-
lized with mucin (1) derived from flax seed, is merthio-
late (II), at a concentration of 1 : 10 000. On the use
of II the biological action of the preparation is somewhat
slowed down. Combined use of antibiotics and gentian vio-
let results in acceleration of biological action but is
unsatisfacto2~y from the bacteriological standpoint. Ste-
rilization of UAe emulsion does not affect its stability
and biological properties. It was confirmed that the use

TEIXT: The systei;i considered consists of a signal circuit and
a czirriev circuit such tliat tho signal is split into three com-
potionts shi-C-ted in phase by 1200 vrith respect -to each other (by means
of wideband phase-shift networks) and the carrier is similarly split
into three Sihase-shifted components by narrow-band networks.
The components are combined by three amplitude-modulators and then
added so that tile output signal has a frequency fl - to , where _S'_
is the carrier- frequency and w is the signal-frequency. If ideal
plla~;c---Aiift networks and amplitude-inodulators were employed, the
carrier frecluency and tile othcr- s1deband in the input signal would
be entirely suppressed. However, due to the inaccuracies in the
[)h,xse-:Ai,Lftcrs and modulators, only a finite suppression is
achio
ved. The stippression of tile undesirable sideband can be

are inferior to those calculated from the formulae due to the

Abstract: Two variants (A and B) are proposed for the synthesis of
2,4,5-trichloro-phenoxyacetic acid (I), which is a herbi-
cide and a growth regulator for some vegetables. A. 2,5-

Title On Ultraviolet Absorption Spectra of Some Nitro and Halogenoni-

Abstract A study was made of the influence of the length of the alkyl
group (RI) and halogens (X) on ultraviolet absorption spectra
of aitrodiols with the general formula R -- CHOH -- CM02X --
CHOH -- R. It is shown that increasing the radical R(R ~ CH
n -- CP71 (CH3)2CHCH2) in the nitrodiols deepens the nw_xi~Q
of the ba'nd of the nitrogroup in the region of 270 -- 280
millimicrons. In chlornitrodiols these macims, become weaker
and in certain cases the curves have merely a point of in-
flection. In bromaitrodiols there are only points of inflec-
tion.

is missing. In the spectra of V and VI a bend is seen near
270 -- 275 millimicrons. The weakening of the absoprtion
band of the nitro group is due in all probability to the
steric influcence of the cyclohexane ring on it, and in ad-
dition to the existence of a hydrogen bond between the nitro
and hydroxyl groups. It is possible that the hydrogen bond
is weakened by introducing the halogen into the molecule.

TITLE: Twin Systems of Automatic Phase Synchronization
PERIODICAL: SM(lovaci technika, 1959, Nr 11, pp 409-411
ABSTRACT: In the introduction, the author describes the princip-
le and practical application of automatic phase syn-
chronization, which was already the subject of sever-
al articles in Czechoslovak literature. A schematic
diagram of automatic phase synchronization is present-
ed in Fig 1. The band of active synchronization is
an important parameter of automatic phase synchroniz-
ation. This is the frequency band in which automatic
phase synchronization is capable of reaching synchron-
ism. The second important parameter is the noise
filtration which is, to a considerable extent, deter-
mined by the corrector circuit. Two kinds of pro-
cesses take place in the automatic phase synchroniza-
tion: the first stage in which the automatic syn-
chronization reaches synchronism and the second stage
Card 1/4 is that of maintaining synchronism. Twin systems o

Twin Systems of Automatic Phase Synchronization

automatic phase synchronization are those which
operate in a certain way during the first stage and
in another way during the second stage. The author

proceeds, describing the classical automatic phase
synchronization with a frequency detector, which is
a possible method of achieving a twin system. This
frequency detector, whose frequency characteristic
is illustrated in Fig 2a, must distinguish between
the two stages. One of its possible connections is
shown in Fig 4. It is composed of 2 phase detectors
fed by synchronizing voltage and by voltage from the
controlled oscillator. The functioning of the fre-
quency detector is presented in Pig 5, in which the
voltage in the various points is given. The fre-
quency detector can find an application for the re-
combiner of color reference signal in a color TV set
(Fig 06). Further, the author deals -mith classical
automatic phase synchronization with an oscillator.
If the system does not reach synchronism, the oscil-

age brought to the grid of the reactance tube. Does
the controlled oscillator reach the frequency of the
synchronizing voltage, the classical automatic phase
synchronization starts functionirg and the auxiliary
saw-tooth voltage switches off. An example of such
a circuit is given in Fig 7. The next systems ana-
lyzed are twin systems of automatic phase synchroniz-
ation -Nith a switched over corrector circuit. With
an adequate switching over of the corrector circuit,
the builder can obtain in the automatic phase syn-
chronization a wide band of active synchronization
and a great resistance against -noise (Fig 8). Final-
ly, the author deals with a twin system of automatic
phase synchronization with quadratic phase detector,
whose circuit diagram is illustrated in Fig 9. The
input synchronizing voltage is brought to two phase
detectors F1 and F2' The phase detector F 1 is a
part of the automatic phase synchronization while
Card 3/4 the quadratic phase detector F2 determines the wa

of functioning of the whole system. In his conclu-
sion, the author stresses that twin systems are
resistant to noise and make it possible in the same
time to choose a more or less independent band of
active synchronization. There are 3 circuit dia-
grams, 2 graphs, 4 diagrams and 14 references, 9
of which are Czech, 2 US and 3 Soviet.

TEXT: Patented is a circuit for phase synchronization which differs from
existing circuits by a considerable noise reduction. The system contains, con-
nected into the circuit of the correcting element, an electronic switch con-
trolled by the phase detector, in turn connected to the input of the comparison
detector and the output of the synchronized oscillator.

PERIODICAL: Technick6 noviny, no. 39, 1960, 3
TEXT: The Turnovsk6 brusirny (Turnov Grinding Works) is the only
Czechoslovak producer of watch jewels. The production of these
jewels requires more than 40 machine operations. Split pear-
shaped ruby boules are glued on boards and mechanically sliced.
Slices are then cut into cubes which are glued bnto small rollers t
be rounded and provided with 0.07 mm. holes. Subsequently, they are
ground to the required diameter and provided with oil sinks. After
final grinding and polishing the rubies are checked on measuring
instruments and inspected under microscopes. Technologist Josef
Janata, cutter Jan Resl and grinder Jana ChmelikovA are mentioned
in the article. There is 1 figure.

nected parallel to the crystal. However, the possibility to reduce the oscillator
fr-qus.a3y by increasing the capacitance (C ) is limited, since circuit attenuation
is also increasing to a value, which cannot be compensated by tube transconductance
and the oscillation stops. To increase the oscillator frequency, :~he capacitano-z'

leplaced by a reactance tube which acts as variable capacitance. The tuning
C?.p7ioity of the.reactaxide tube is rather limited, but can be increased, when the
.'a-d zesi-szanise (R3) of the tube is replaced by an inductance. The equivalent
cir-Luit of such an oscillator is 5hown in Figure 9, in which CRD = variable capac-
of the rea2tance tube; RRE = resistance effected by the reactance tube;
CRS = s~~bl& capacitance of the reactance tube plus mounting capacitance; LRO
= -~lxning inductanc-e; Cvl, Cv2 = coupling ca~acitances; COK = stable capacitano-
cf tne zrystal; and LK, CK,RK = dynamic equivalents of the crystal. To maIK~e oz-
~~illa-.ion posztible, the impedance on the left side of terminals ( 1 - 1) must have
inductive character. The circuit on the left side of terminals (2 - 2) can be re-
garded as simple-tuned circuit. A decrease or increase of its resonance fre-
qu~yicy effects a-so a decrease or increase of the oscillator frequency. In C-.53e

quency can be provided by adjustment of the inductance (LRO) or bychanging the
bias of the reactancetube. A 50% change of capacitances (Gvl) or (Cv~) effected
a 250 CPS frequency change (measured at er = 0). Changes of resistance (RT) or
capacitance (Co) have negligible influence on the frequency. A 15% change of (CO)
effected a 4N, change of output voltage. A temperature increase from 25 to 750C
and a tuning transconductance-of SR = 700 cps, effects a frequency increase of 130
cps. During 8 hours of operation, the frequency did not fluctuate more than t 50
cps. Exchange of reactance tubes produced a large influence on oscillator fre-
quency,.due to varying attenuating capacities of different tubes, amounting to a
deviation of +320 cps for 9 arbitrarily selected tubes. A change of the anode -
voltage from 240 to 360 v effected a frequency increase of 250 CPS, a change of
the filament voltage from 8.8 to 9.8 v effected an increase of 100 cps. There
are 10 figures and 2 references: 1 Soviet-bloc and I non-Soviet-bloc. The ref-
erence to the English language publication reads as follows. T. Buchanan, Hand-

Abstract: '17he authors studied the effect of storing on the
oil content of a number of plant substances, u1nich, accordinl-
to Schou, is the measure of the active bodies in pharmaceu-
tical preparations. They found that for substances where
the oil is intracellular, oil content decreases, i%hereas for
substances with extra-cellular oil, the content both increases
and decreases. 7he show their findinas in one table and 17
t-, r a p Ins. ComDarison of their findings with those in the liter-
ature decided the authors on a more detailed study, to be
reported later. Mere are 18 referencest 6 Polish, one (1)
