TITLE: The design of negative-feed-back amplidynes made of
transformer steel (0 raschete magnitnykh usiliteley

PERIODICAL; Vestnik Blektropromyehlennoati, Nr,ll, 1958, pp-1-4

ABSTRACT: A method has been proposed for designing amplidynes with
internal negative-feed-baek that is based on representing
the core material by an idealised characteristic. If the
usual relationships are applied when the amplidyne core is
made of transformer steel, determinations of the character-
istics become inaccurate. Such errors are reduced when
the circuit with magnetic amplifier and active load is
represented by the equation of an ellipse. This article
is concerned with amplidynes having internal negative-
feed-back and cores mede of transformer steel. The
corresponding circult:supplying a load with rectified
Card 1/4 current is given in Fi[;~I. The special operating features

of this amplidyne are revealod in Fig.2, which gives current
and voltage oscillograms during half-wave rectification
for two different circults; Fig."3a pertains to a Goreloss
mutual induction coil and Fig.2b to the circuit of Fig.!
in which the amplidyne, core is made of steel grade F,,3-10.
The current and voltaE;o wave-forms are discussed and
expressions are derived for the currents in the tV.-a. windings
and in the load. S.m.f. equations are then derived. From
these, equation (6) is obtained which expresses the B-H
relationship in the form of an ellipse with its centre at
the origin of the coordinates. Fig.3 shows B-H curves
with simultaneous msgroatisation. of the stool by half-mave
and direct current. The dotted curve corresponds to
a~c* magnetisation. By oombining the ellipse of equation
( ) and the characteristics in Fig.3, the required charac-
teristie of the magnetic amplifier is readily obtained.
An expression is-derived for the current form-factor.
Characteristics obtained wit-h various values of resistance
in the control circuit are plotted in Fig,,4. With low
Card 2/4 values of load resistanoe, voltage-drop in the load is

commensurate with that In the rectifier. To allow for
reitifier impedance It Is necessary to know the
operational volt-ampere characteristic for pulsating direct
current. This Is best derived from the static or d.c.
characteristic by calculation. The static and operational
ch!iracteristies for sellanium rectifiers, previously pub-
lished by another author, are plotted in Fig.5- The
method of determining the horizontal somi-axis of the
ellipse from these curves is explained. uxperimental
investigations have shown that by using the characteristic
for simultaneous magnetination of tho steel with half-
wave and direct current and applying the ellipse equation,
the load characteristic can be calculated to an accuracy
of 5 - 10%. It is necessary to use magnetic characteristics
obtained for the same control circuit impedance as is used
Card 3/4 in the magnetic amplifior. The procedure here described

cipal construction parameters of magnetic amplifiers-i6 describ-

the rectifier bridge because of the current at the moment of

germanium valves the voltage drop at the bridge can be neglect-
ed. The linear inductance at the input of the-rectifier bridge
is investigated, and on the basis of-the oscillograms recorded

tions of the circuit is equal to the mean value of the voltage
of the source. A circuit with a magnetic amplifier at the input
of the rectifiers, and a magnetic amplifier with internal feed-
back at the input of the rectifiers are then'investigated.- It
is shown that the use of the voltage mean values in the calcula-
tion of circuits with inductive load fed with rectified current
greatly simplifies the calculation of the magnetic amplifiers.

ABSTRACT: Possibilities and prospects are considered of using a germanium
junction transistor as a device for regulating the voltage of automobile
generators in-stead of the vibration-type voltage regulators now used. In a DC
circuit, the junction-type transistor is actually a controllable resistance whose
value can be changed from a few tens up to a few thousand ohms. Connected in
series with the generator field winding, it can be used to control the generator
voltage. The commercially available P4 type transistor ensures control of

on its enclosure). Its life is 5,000 hours. If larger currents are desired, a
number of transistors can be connected in parallel. These two transistor
scheme types (I or more parallel - connected transistors) are presented:
(1) smooth regulating schemes (the, transistor resistance is varied continuously
as the controlling voltage varies); (2) vibration regulating (discrete) schemes
in which the transistor functions as an "on-off " device; the switching is
performed by a vibration-type low-power regulator connected in the base circuit
of the transistor. A speed-up resistor is connected in the above schemes.

1-111E: Surface smoothness of machined heat resistant Nimonic 80 alloy
PERIODICAL: Technika Lotnicza, no. 2, 1960, 44 52
TEXT,! The article deals with investigations of this problem with respect
to production,of turbine engines, carried out by the Katedra Wytwarzania Silinik6w
Lotniczych PW (Department of Aircraft Engine Construc~ion of the Warsaw Polytech-
ulc)~ The machinability of Nimonic 80_depends on its hardness and elasticity and
is influenced by the "soften,ing" (Wyplyw) phenomenon, caused by high tem Iperatures,
described by B. N. Ilyin [Ref. 1-..Cutting Properties of Austenitic Steels]. Re-
quirements for a successfull machining of Nimonic 80 are: high stiffness of ma-
shines and tools, accurate distance between tool and workpiece; cutting speed not
ovirpassing 1Q m1min; exact surface of tool and suitable cooling. Tests were
carried out on Nimonic 80, heat. treated at 1,0800C during 8 h, aged at, 71000 during
16 b and cooled at room temperature. The mean mechanical properties of the test

inclin&bion au = 120, angle of rotation ru = 200, angle of tool Xu = 300, Zp = 10'~',
reduced tool edge r = 0.5, 1, 2, 3, 4 mm. The PSH24 grinding wheel driven ~y a

An exaMination of the advantages and the technique of cold rolling.
It enables rolled materials of uniform thickness and clean glossy surface
to be obtained, and due to sui-table strain endows it with the required
streng-th. Description and characteristics of the riost common rolling
mills, the gradual development of them characterized by the width of the
sheet which is now up to 2300 mm, its thickness, and the speed of rolling
up to 400 m/min. Examination of work of some U.S.S.R. and Ami:)rican
rollin.- mills, with a sketch and output figures of the rolling mill
