TEXT; The Miller integrator using tubes is inconvenient if trans-
istors are used, si ce it requires a very high amplification factor
(of the order of 109 to 106 J. More convenient is the integrator
whose block-diasram is given in Fig. 1c, with amplification factor
Ku a 1, with which a high input-resistance (ri;~ rc) can be easily
obtained. It is essential that the high input-resistance is obtain-
ed from the feedbach resistance Re and the current amplification of
the circuit only, and does not depend on the small input resistances
of the transistors which change with temperature and operating con-
ditions. Fig. 2a represents an amplifier with K. - 1 and with high
ri . 100 megohm. An advantage of the proposed integrator over the
Miller integrator consists in the compensation of an error due to

leakage through ri (Fig. lc) by a slight increase in Ku. Fig. 2b
represents an amplifier by means of which any stable and pre-set
value of Ku can be obtained; such a value of Ku, slightly more than
unity, is needed for compensating the capacitor discharge

The circuit remains stable also with small overcompensation. The
amplitude characteristic of the amplifier of Fig. 2a is also given.
The integrator works with a positive feed-back and is distinguished
from the usual integrators of such type by incorporating as an am-
plifier a three-transistor amplifier with Ku a 1. The actually
obtained characteristics of the integrator are given in the Table.
The linearity of the amplifier is upset at output voltages above
+ 4.5 V. Much better results could be obtained by using a 4-tran-

nickel alloys, the negative effect of boron Is very mArked at A higher content
( > 0.0 1 - 0,02% ) than In austenite steels ( -- 0.005 - 0,007%) . Proneness to
hot cracks in the weld-adjacent zone of austenite stools and nickel alloys can
be reduced by refining the base metal with the aid of electric slog remelting
or vacuum molting, -ain refining, and Increasing the quenching tomperature
within the limits of a permissible grain size. All these methods reduce segrega-
tion of alloying elements and harmful impurities at the grain boundaries: the
former, indirectly, by reducing the total amount of Impurities In the alloy and.
by their more uniform distribution; the latter two, directly, by reducing the
concentration of elements and Impurities at the boundaries. The study was

EMI and EM2 are electromagnets, PC I and PC 2 are
moving coils, FD1_4 are photo-electric pick-offs,

compares the torques proportional to the product of
the current in the coil and the air-gap flux density.
A feedback circuit using the pick-offs and amplifiers
obliges Eq (1) to be observed. Since fixed resistances
are connected in series with the coils, the instrument

220 x 135 x 180 mm Although the use of feedback
avoids errors due to amplifier drift or temperature
instability of the pick-offs, the instrument is still
vulnerable to parasitic mechanical torques. The
maximum working torque is 1* gm.cm. The_ rror
contributions are those og friction (10 S gm.cm), the
flexible connections (10- gm.cm), misalignment and
out-of-balance. The misalignment effects are due to
the inclusion of small ferromagnetic particles in
undesirable places. The capacitances C and C4
shown in Fig I are necessary to provent the system
breaking into self-oscillations. The maximum input
Volta5e is 100 V, the aceux-acy in multiplication is
1.10- and in division 2.10-3. The frequency response
is flat to 0.5 cls. G. A. Martinov is thanked for

PERIODICAL: Pribory i tekhnika eksperimenta, 196o, No. 6,
pp. 122 - 123
TEXTi An instrument is described which is intended for measuring
magnetic surge fields between I and 1 000 Oe with an accuracy
not less than +; 2-3%. The instrument is based on utilising the
Hall effect, i,e, ttio Hall e.ni,f., which is highly sensitive
to the applied voltage (Ref. 1). Of the hitherto investigated
materials n -- Ge has the highest sensitivity. In no-load V
operation the basic source of error of the instrument is the
temperature dependence of the Hall e.m..f.. which i-, lue to
of the dependences of the concentration and the mobility of the
current carriers on the temperature n(T 0) and p(T 0) -
Their relative importance depends on the supply circuit of the
pick-up,, To ensure normal operation of the pick-up, "contact
phenomena" have to be excluded. For this purpose it is

necessary that the contacts should be non-emitting, non-
rectifying and they should have a low resistance.. Good
contacts can be obtained by grinding tile surfIce. followed
by pickling in a solution consisting of 10 cm- hydrogen
peroxide and a few drops of liquid ammonia. The contacts
should be soldered by tin alloyed with 10% antimony.. A
diagram of the basic circuit of the instrumont is included.
The Hall probe is fed from stabilised 6-rjuij)ment. which
ensures thermal stabilisation of the Hall e.m.f. by changing
the intensity of the current which flows throtigh the probe.
As a temperature pick-up a normaUybarred diode is used,
which is connected in parallel to resistances. The diode is
in thermal contact with the Hall pick-up. By varying the
impedance of the divider (by changing, the resistance RI)
tile change in the current intensity with temperature
in the range of 20 - 40 OC call be obtained which is necessary

TIBXT; The authors recommend new circuits for current and voltage
amplifiers, and for voltage-current converters, in which the usual
limitations on the input and/or output impedances are removed. They
show that the high output impedance can be obtained only by apply-
ing positive feedback. In existing feedback current-amplifiers the
output impedance is limited by the collector resistance of the out-
put transistor for any appreciable degree of feedback. High output
'Impeuance rout '>> rCcan be achieved by using a small amount of po-
sitive feedback, as shown in Fig. 2, in addition to the overall ne-
gative feedback. This multi-loop feedback circuit imp3~oves 'the sta-

changes in the properties of the active elements. The output impe-
dance is between 50 and 300 megaohms, Analytical expressions for
the amp4sification, input and outp% impedances are given in the pa

of local positive feedback. The same principles tire used In z~;-

pressions for the slope, input and output impedances are given.
H~th input impedance in voltage amplifiers can be obtained with
parallel-series negative feedback. The circuit shown in Fig, 4 has
an input impedance between 500 and 2000 mQgohms. Stability of thp
voltage amplification against changes in the operating conditic.is,
temperature or transistor replacement are ensured by the series-
parallel negative feedback which increases the input and redtices
the output impedance. The 'limited power amplification of the Ira-
sistor, however, makes it possible only at the cost of reduciz,qg

TITLE: Precision transistor integrator
PERIODICAL: Avtomatika i telemekhanika, v. 22, no. 7, 1961,
907-913
TEXT: The Miller integrator using tubes is inconven4ent if trans-
istors are used since it requires a very high tunplification factor
105 t 1 6 U
(of the order oi 0 0 ). More convenient is the integrator
whose block-diagr,-n is given in Fig. 1c, with amplification factor
Ku - 1, with which a high input -resistance (ri;~, rc) can be easily
obtained. It is essential that the high input-rcsistance is obtain-
ed from the feedback resistance Re and the current amplification of
the circuit only, and does not depend on the small input resistances
of the transistors which change with temperature and operating con-
ditions. Fig. 2a represents an amplifier irith ~u a 1 and with high
ri = 100 megohm. An advantage of the proposed ixitegrator over the
Miller integrator consists in the compensation of an error due to

leakage through ri (Fig. lc) by a slight increase in Y,,. Fig. 2b
represents an amplifier by means of which any stable and pre-set
value of Ka can be obtained; such a value of Ku, slightly more than
unity, is needed for compensating the capacitor discharge

The circuit remains stable also with small overcompensation. The
miplitude characteristic of the amplifier of Fig. 2a is also given.
The integrator works with a positive feed-back and is distinguished
from the usual integrators of such type by incorporating as an am-
plifier a three-transistor amplifier with Ku = 1. The actually
obtained characteristics of the integrator are given in the Table.
The linearity of the amplifier is upset at output voltages above
+ 4.5 V. Much better results could be obtained by using a 4-tran-
C ard 2/6

Silicon diodes are used against overloading; the errors due to
these can be limited by suitable choice of C. The above amplifier-
circuit can be also used for other linear operations with the given
transient functions. There are 6 figures, 1 table and 5 references:.

ABSTRACT: The process of destructive hydrogenation of crudes and
residues under a moderate pressure In a circulating
stream of a catalyst developed by the Petroleum Institute
of the Academy of Sciences USSR (Ref 1) requires the
application of catalystslwhich are resistant to wear.
An investigatior-i-o-f-TH-e influence of conditions of
preparation of aluminonickel catalysts, containing 10% of
nickel oxide, on their mechanical strength is described
in the present paper. The experiments were carried out
