TEXTo This paper provides a general analysis of the selec-
tive four-pole interworking at the input and output with a resonant cir-
cuit. The classification of the selective four-pole introduced in this
paper is based on two coefficients determining the internal feedback of
reactance type defined by

The selective four-pole D265YD303
The analytical considerations show that the loop gain of a selective
four-pole is proportional to the values of n and m coefficients in the
case when X X2j : 0. Selective four-poles are divided into 4 groupas
nmp mp ng ala ~n a 0. The first two groups have asymmetrical trans-
mission characteristics and the remaining two groups have characteris-
tics symmetrical with respect to the resonance frequency of circuits.
The "above classification enables the uniform representation of such ba-
sic circuits of a receiver as a one-stage resonance amplifier, a-mixer,
a negative impedance amplifier and an absorption circuit parametric am-
plifi-r. The relations determining the real and reactive parts of the
inj,O. impedance as well as a transfer ftnotion of a selective four-pole

The selective four-pole D265/D303
is derived, K 1 . Q11/Q22 being the coefficient influencing the rela.-
tive mistuning of the resonant circuit. As an example of the applica-
tion of the analysis presented in this paper, a selective amplifier
with a base intermediate between the grid and the cathode is investi-
gated, for which no adequate analysis was otherwise provided. Capaci-
tive and capacitive-inductive bridge circuits are replaced by an equi-
valent n-type selective four-pole. Results are also presented in the
form of tables giving the circuit parameters using the selective four.-
pole for the basic circuits of valve and transistor amplifiers and the
parametric amplifier with a capacitance diode.. The analysis is most
suitable for solving more complex networks such as those consisting
of a chain of selective four-pole interlocked by resonant circuits.

TITLE: NeutralJzation of selective amplifiers
PER10i;ICAL: Przeglqd telekomunikacyjny, no. 11, 1961, 339-342
TEXT: Simple methods of neutralizing low,paper selective ampli-
fiers are discussed. Some pointers have been given on how to mak2
the neutralizing bridge independent of frequency response. To note
the admittance variations with frequency of a neutralized ampli-
fier, the use of an oscilloscope is suggested. The variations of
the input admittance can also conveniently be detected by measuring
the input voltage which is inversely proportional to the input ad-
mittance.

where U input voltage, E - signal generatorlo E.M.F., G - inter-
nal admittance of tile signal generator, Y AB - input admittance of
the amplifier under test, Observing the voltmeter indications on
the input to the amplifier, the neutralization bridge can be ad-
justed; the same method is also useful in detecting any parasitic
oscillations of the amplifier and in determining its input admit-
tance. An improvement on the voltmeter method is that of using a
sweep frequency generator and an oscilloscope. Six oscillograMS
are shown to illustrate this method. To ensure that the neutrali-
zation of tile amplifier covers a fairly wide frequency band, care
must be ta"Ken for tile arms of tile neutralizing bridge to exclude
all unwanted frequency dependent components other than the bridge
capacitances. This is illustrated by six simplified circuit dia-
grams. There are 5 figures and 3 references: 1 Soviet-bloc and 2
non-Soviet-bloc. The reference to tile Engllo`.-lari;,ua~re publication

valent circuit of the amplifier is studied using standard desiena-
tions. At higher frequencies the neutralizing bridge can be assumed
to consist of capacitances alone. The two conditions of neutrali- Z

TITLE: Novelties From the Field of Metallurgy. Steel Industry'! The Pro-
gress of Vacuum Metallurgy in World Iron Metallurgy on the Basis of
1959 Literature
PERIODICAL; Hutnik, 1960, No. 9, PP. 348 - 354
TEXT: This article is divided into two parts, with sub-titles: a) de-
gassing of liquid steel in vacuum, b) melting and pouring of steel in vacuum.
The author selected 34 of the most important works from the 1959 world litera-
ture dealing with problems of steel degassing and presents a short r6sumb of
each. Sokolov and Oyka (Ref. 1) produced an indicating method, allowing for a
quantitative valuation of liquid steel degassing procedure. By applying this
method, they found that 80% of gas escapes during the first 3 - 4 min from the V/-
ladle after It was placed in a vacuum chamber. Liquid steel convection move-
ments in the ladle contribute to mixing and better degassing. Samarin and Novik
(Ref. 2) compare Bessemer and openhearth steel properties. The former Is of

inferior quality because of P, S, N and 0 content. By degassing Bessemer steel
in vacuum, 77.5% of oxygen, 52.3% of hydrogen, but only 10 - 15% of nitrogen es-
cape. The quality of steel has improved, especially Its shock resistance at
low temperatures. Antropov and Guryevich (Ref. 8) investigated the influence of
deg assing on electrical steel properties. ti EI 72 steel tends to f orm nmch less
of internal capillary cracks after degassing and, therefore, the amount of
scrap dropped by 50%. After degassing it contained 30 - 50% less hydrogen and
20 - 30% less oxygen. Degassing of steel during the crystallization period in
the mold deteriorates its structure and contributes to shrinkage cavities for-
mation. K. Radiwicki (Ref. 21)Fresented the results or InveBtIgatlons carried
out at the Instytut Metalurgii Zelaza (Iron Metallurgy Institute) In Gliwiceon
forging properties of steel with high nickel content. Ingots from degassed
steel showed better forging properties and less transcrystallization. These ex-
periments will be repeated on industrial scale. Pryandshnikov (Ref. 23) dis-
cusses the trial smelting of transformer steel in vacuum-induction furnace of
150 kg capacity. It was found that transformer-43teel quality Is better if the

charge melts In atmospheric conditions and only working and deoxidation of same
takes place in vacuum. Pour-Ing of this steel should be carried out rather In a
protective atmosphere and not in a vacuum; on the other hand, addition of FeS1
should be done in vacuum and after addition the melt should be kept under vacu-
um for about 10 min. Pressure forming and magnetic properties of steel prepared
in vacuum were better than In conventional steel. Shabanov (Ref. 24) explains
some problems connected with steel smelting In arc ovens with a melting elec-
trode, and he produces a formula for the calculation of the ratio between elec-
trode and crystallizer diameters. lie also found that a) current density should
be adjusted with reference to the electrode diameter, b) metal losses diminish
with increased electrode diameter, c) the content of alloy components may vary
within a wide range, d) content of oxygen in steel molten at a pressure of 1 Tr
or lessidrops 2.5 times or more. Byelanchkov and Grylgorash (Ref. 32) examined
the Influence of various technological factors on degassing of steel melted in
vacuum-arc-ovens in crucibles of 2 and 7 kg capacity. Increased melting speed
acts adversely on hydrogen and advantageously on oxygen and nitrogen escape.

The optimum ratio of electrode-to-crucible diameter was established to be;
D + d - 0.77. An article under the title "Rolling Ways for Extension of Service
Life of Heavy Type RR Rails in USSR", written by Doctor of Engineering Danilov,
appeared in an official organ of the USSR Ministry of Transportation "Zhelezno-
dorozhnyy Transport" 1960, No. 3. The author states that heavy RR rails R50 and
R65, used on heavy traffic lines, proved not to be strong enough, especially on
the inner arcs. Rails which should withstand 500 million tons load gross have
shown faults already after being exposed to 50 - 60 million tons gross, marked
in an official faults register as No. 64 and 82, i.e., metal overflow, wear and
small cracks of fatigue type. The author thinks that a radical way to Improve
the matter is to use a better quality steel for RR rails. For the time being,
however, the author suggests a nertes of temporary measures. 1) To Increase the
cross slope of rails on the outer bend from 1 ; 20 to 1 : 10. This can be done
by inserting between the sole-plate and the tie a wedge shaped pad. This might
reduce the wearing out of rail heads by 20 - 30%; 2) to relinquish the hitherto
applied 1 : 40 cross slope of heavy rails R65 and R75; 3) to clean the rail an-

nually and remove metal flows fl"ing5, etc.; 4) to regenerate rails removed
from main RR tracks; 5) to maintain RR tracks. It might be advantageous to re-
duce the track gauge from 1,524 mm to 1,518 mm; 6) to improve the defectoscopic
method of rail examination in situ; ultrasonic defectoscopes as used In metal-
lurgical plants for sheet thickness control can be applied; 7) to reduce the
dynamic action of wheels against rails. Investigations In the direction of Im-
proving steel quality are going on for several years, but without any positive
results. They are: a) hardening the whole length of rails, particularly those
for bends, b) investigations on improving steel quality by addition of some lm-
ported noble additives, e.g., manganese in relatively large proportions of 12 -
14%. This is an expensive way, but in the long run It might be justified to do
it. There are 34 references: 6 Soviet, 1 French, 11 German, 14 English and 2 A-
Polish.
