-40 kg capacity, and in an experimental 350 kg converter with basic fettling. In
the course of the first 5 minutes the Si is oxidized down to traces, Mn by 80% "
The oxidation rate of the carbon content at constant 02 feed rate is not uniform .
At the beginning of the blow-through it constitutes 0.2-0.3% C/min and as the
blowing continues it grows to 0.25-0.45% carbon/min, and at the end of the blow-
through a d~o~ In the decarbonization rate down to 0.1-0.3 % C/min is observed.
The effect of 02 feed rate and the distance between the tuyere and the vat surface
upon the sequence and oxidation rates of C content and P content at the end of
the blow through was studied in the 40 kg furnace. The rate of 02 supply varied
between 100 and 150 liters/min, and the tuyere distance - between 25 and 40 mm.

TITLE: The quality of steel produced in a duplex-process converter-
electric furnace
PERIODICAL: Izvestiya vysshikh uchebnykh zavedeniy. Chernaya metallurgiya,
no. 9, 196o, 50-56
TEXT: The use of a duplex-process converter-electric furnace had
been decided by the XXth congress of the CPSU, and experiments were necessa-
ry in view of no previous experience with this method at the USSR plants.
The goals were; 1) To study the process in a converter with an oxygen
blast, and the process in an electric furnace using the converter steel;
2) To compare the process in the electric furnace with solid charge with
the process with the liquid semi-product; 3) To evaluate the quality of
steel produced by the duplex-procose. Liquid metal for arc furnaces was
produced in converters of 40 and 350 kg capacity with the oxygen blast from
the top; steel from the first converter was poured into a 100 kg are furna-
ce and from the second into a 500 kg arc furnace. Open hearth pig iron

molten in the 350 kg converter contained 3.86-4.34% C; 1.19-2.63% Fin; 0.29-
1.06% Si; 0.095-0.23% P; 0.019-0-050% S; o.oo84-o.0133% N2. It was mel-
ted in an 0.5 ton electric furnace with basic lining and poured into the
converter; blasting started at 1260-13200C in metal, at a rate of 30-60 m3/
ton; blasting lasted 7-13 min. The change in chemical composition of the
metal in a small converter was practically the same as in melting in large
converters (Fig.1). The electric furnace process was szudied in melting
WA15 (ShKh15) and '145" steel, in 100 kg and 500 kg are furnaces with basic
lining. For ShKhA5 steel the charge in the 100 kg furnace consisted of
70-75% scrap metal and 25-30% liquid semi-product; two heats were melted
with oxidization with iron ore and gaseous oxygen, and one without oxidizing,
four heats were melted with solid metal charge and oxidation for comparison.
In the 500 kg furnace two heats were melted with a liquid semi-product;
slag mix from lime and fluorspar; the bath was oxidized with iron ore and
oxygen. Three heats were melted for comparison with a solid charge and iron
ore. The reducing period in both furnaces was carried out with carbide
slag and ferrochrome addition directly onto the bath surface. Steel 11451,
was melted from a liquid semi-product, with slag mix of lime and fluorspar,

starting oxidization with iron ore and oxygen after the formation of slag.
Two heats were melted with solid charge by conventional techniques, with
iron ore for oxidizing. The behaviour of nitrogen was different in the two
steel types, which may be explained by the difference in the reducing period
conditions. The conclusion was made that nitrogen content in ready steel
did not depend on the nature of the metal charge. The steel quality was
evaluated by macrostructure and mechanical properties. All ingots were
solid; the development of the transcrystallization zone did not depend on
the composition of the metal charge and oxidizers; the crystalline structure
was determined by the tapping temperature; the metal grain size was also
not affected by the nature of the charge, it was obviously determined by
the final deoxidizaticn (both steel grades were deoxidized with aluminum).
The conclusion: steel melted from a liquid semi-product is the same as
regards its mechanical properties as steel melted from solid metal. The
mean heat time with liquid semi-product was 2 hr 05 min (or 40-7%) shorter
than with solid metal in melting ShKh15 steel, and 2 hr 02 min (45%)shorter
in melting 1145" steel. The electric power consumption was reduced 37-1%
and 35.7% respectively. General conclusions: 1) Steel melted from a liquid

A161/AO30
semi-product is equivalent with steel melted from solid metal in the content
of nonmetallic inclusions, oxygen and nitrogen and in its mechanical proper-
ties. 2) The duration of heat with liquid semi-product is nearly twice
shorter, and the consumption of electric power nearly 40% lower. There are
4 figures and 3 tables.

TITLEs The Terminology in the Field of Transistor Electronics
PERIODICALs Izvestiya vysshikh uchebnyl-Ji zavedext iyj Radiotekhnika, 1959, Vol

ABSTRACT- The authors refer to the article by T.M. Agakhanyan, B.N. Kononov
and I.P. Stepanenko, titled "The Terminology in the Field of
Transistor Electronics", published in Izvestiya vysshilch ucheb-
nylvh zavedeniy, Radioteldmi-ka, 1958, Vol 1, Nr 4. The authors
agree in principle with the suggestions made in the aforemention-
ed article and present some of their own ideas as an addition.
For example the Russian terms "bazo:" (base) and 11tranzistor"
(transistor) should be sanctioned, although there might be some
conflict with the term "poluprovodnikovyy diod" (semiconductor
diode) which altio bolongs to tho trt~naistor class. The nuthors
regard the terms 11dyrochnyy tranzistor" (1holel tritnaistor) nn(I
"elektronnyy tranzistor" (electron' transistor) as superflous
and recommend the designation p--n-p or n-p-n transistor. Similar
Card 1/2 suggestions were made for the classification of diodo types.

as the basic factor determining the noise properties of transistor
amplifiers. Possibilities are considered o-;-- replaciiZ; the transis-
tor noise by a noisy four-pole of the equivalent transistor circuit,
having internal noise sources. The bloc-diagram is given for mea-
.?uring the noise parameters. Formulae are given for evaluating F
in the region of white noise and at HP from the equivalent circuit
of Giacoletto, containing 4 uncorrelated noise sources corresponding
to the following: Thermal noise of the ohmic base resistance; shot

noise of d.c. and thermal currents through the emitter transition;
the shot noise of the collector current component, due to the emit-
ter minority carriers tranqressed into the base; the shot noise
of the thermal current pausing through the collector transition.
The circuit applies to the region of white noise. Examples are
given of evaluation of V in the region of white and redundant noise
and also at HF. A short exposition is given of the direct and modu-
lation method and of the comparison method as used in measuring F.
A detailed description is given of the arrangement for measuring
the noise factor by the method of comparison of a noise generator
with a sinewave generator in the frequency range 0.16-20 and 30 ~

T=1: Analytic relations are derived between the period of the first
stage of discharge evolution in the pulse thyratron, beginning at the moment
the positive grid pulse is fed and continuing until the grid current is in-
creased significantly, and the shape of grid voltage pulse, gas pressure, and
interelectrode spacing. Approximate formulas are derived on the following as-
sumptions: the field between the grid and cathode is homogeneous and is not
distroted by space charges; the main ionization process is the single-impact
ionization of gas atoms by electrons emitted from the cathode. The curves,
based on the equations of the period of the first stage of discharge as a func-
tion of the pulse amplitude, are confronted with experimental data available in
the literature. There are 8 references. A. R.

TEXT: An investigation was carried out of the mechanism of developing a
discharge in sectionalized thyratrons for a case in which the design of inter-
mediate electrodes eliminates the possibility of a direct transit of the elec-
-trons from the cathode to the anode. The authors assume that, In this case, there
exists a successive discharge firing (beginning with the first one) to the'inter-
mediate electrodes. As a result, the voltage between the sections, In whIch the
discharge did not develop yet, will Increase, and, at some moment, the whole
anode voltage will happen to be applied between the last intermediate electrode
and the anode. Within a given time, the velocities of the electrons passing

TOPIC TAGS: cathode, electron tube cathode, barium oxide, temperature control
ABSTRACT: The core and surface temperatures of an oxide coated cath;1(de perating in
a low pressure mercury vapor atmosphere were determined as functions of the current
drawn from it in order to acquire data that would allow of specifying optimal oper-
ating conditions for oxide-coated cathodes in high current applications. The oxide
coating was deposited on the plane surface of an indirectly heated base of electro-
lytic nickel. The core temperature was measured with a thermcouple. To measure
the surface temperature of the oxide coating, the near infrared radiation from the
surface was focused auto a photoresistor connected into a bridge circuit. The optical
device was calibrated against the thermocouple by assuming that the core and surface
temperatures were equal when the cathode current was zero. Curves were plotted giving
the core and surface temperatures as functions of the cathode current for fixed values
