Abstract: Two instruments were developed, which make it possiDie tc, measil-re
the emf in rocks and under complicated conditions, for example, whei5
prospecting for ore deposits, th eD the transfer resistances vary
from fractions of an ohm to 10 ohms at a considerable level of
noise frOM stray telluric currents, from inductionY etc. On '. tie
basis of these instruments it is proposed to bulid an eLectric
prospecting station. The fij~st instrument is a hifh speed autc-
matic electronic compensator (EK), operating on ttie principle of
static compensation. The uncompensated part of the measured

Pulse-height- and Phase Indicator With Alternating Action
of the Voltages to Re Compared
Izmeritel,naya tekhn,,ka, I No 9, pp . ~9-40
TEXT: The present paper recommends a differential indicator for pulse
heights and phases with alternating action of signals to increase the
accuracy of comparing alternating voltages Fip. 1 shows the block diagram
of such an indicator. It is pointed out that a similar scheme was used
for pulse height measurements by M. R, Bal-son (Ref. 5) and Yu. A. Skripnik.
The mode of operation of the present circuit consists in an alternating
supply of the voltages u, - U., sin ((.)t + ~) and u 2 = Um2 sintit of the
frequency ~-2 e,< i..j to the input of the aperiodic or selective amplifier
(tuned to the frequency (~) ) by means )f a commutator. Thug, the voltage

TEXT; In the introduction It la stated that the investigation of the tranamle-
sion band of a direct current amplifier with converter and the determInatior of
the relationahip between the upper limiting frequency of the signal.6 to be ampli-
fied and the frequency of conversion is of considerable interest Two ;ondltir~n-
which must be satisfied in the determination of the limiting frequenoy of the
band, transmitted by the direct current amplifier, are mentioned They concern
the amplification coefficient and the combination-components The authors
define the half-wave and the full-wave conversion, according to whether the
input signal is interrupted in dependence on the inter-connection of the modulatcr
or whether a phase shift occurs., With equations (1) and (2), formulas are given
for the calculation of the transmission coefficient of both kinds of conversion-

tion. For the demodulator the same connecting systems exist as f3r the moduirtor,
and also the transmission coefficients are calculated according to the same
formulas. Turther, the determination of the transmission band of the direct
current amplifier with conversion at various conneotions of the modulators
and demodulators is dealt with The investigation showed that In the case of
full wave conversion at the in- and output the output signal has no combina-
tion frequencies. By the influence of the intermediate-frequency amplifier
which has feedbacks, the tranamiafjion band is limited.. Fig 1 shows the
frequency characteristic of such a direct current amplifier. It is shown that
the spectrum of the output voltage of a double fullwave conversion has the beat
properties. In conclusion, the authors investigate a direct current amplifier
with a non-synohronous linear detector at the output. A half-wave conversion
is assumed, and analysis shows that this amplifier is useless for the amplifi-
cation of alternating voltages, but may well be used as me&n-va!ue voltmeter
for a large frequency range The mere possibility of producing broad-band
direct current amplifiers with high sensitivity and stability is p~.-nted out

TEXT- Ar electric geophysical exploratiun with several frequencies is
carried out for an investigation into the electric structure of the
earth'5 crust. The method involves measuring the amplftude and the phase,
or the active and the reactive component of signals. The frequencies of
these signals lie in a range of from 25 cycles to 12 kilocycles. The
first method dealt with here is the one in which measurements made at
the individual frequencies are carried out in ti-,e frequency range
provided. A high noise immunity can be attained here by the use of a
high-selective amplifier, and it is therpfore possible to work with

and muitipiication operations are accomplished by means of a va-
riable in~3trument shunt. *hen there is such a ctrcuit the convert-
ing unit is independent of the measuring limit and allows the
equation Pk = K(Z~U/1) to ue solved in one stage. A negative direct-
current feedback is employed to compensate temperature chan6ea in
the device. This ensures the instrument's stabie operation in the
temperature range from -20 to +600C. The principle of the device's

TOPIC TAGS: flip flop circuit, phase splitter, phase shifter, frequency divider,
TRANSLATION: In order to eliminate the phase shift error in quadrature phase split-
-ters with flip-flop frequency dividers, absolute voltage symmetry is necessary at
,the input of the differential circuit. This condition is impossible in a sufficient-
wide dynamic frequency range for previously described systems. Therefore the au-
thors propose the addition of an intermediate flip-flop with a following differen-
tial circuit. Schematic and time diagrams am given together with a brief descrip-
tion of the operating principles of the proposed improved device. It is known that
the unit gives a highAy accumte quadrature of square voltage in a wide dynamic and

frequency signal range, and may be used in circuits for rms addition of voltage with
'two-phase frequency conversion, synchronous quadrature and quasi-synchronized signal
reception, etc. A schematic diagram is given for a model of the unit which is used
for experimental testing of its operation. It is found that the total phase shift
lerror, due mainly to instability in flip-flop operation, is less than 0.110. Quadra-
;ture and symetry of the output square-wave voltages are held with a high degree of
accuracy when there are changes in the input signal: (a) in frequency fr*m 400 to
10,000 cps and W In amplitude from 0.1 v (minimum value) to + 40 db. The frequen-
cy range for this circuit may be expanded.

ABSTRACT : Replacement of solid cylindrical cores 1,y equivalent hollow cylindrical
cores leads to reduction of core weight. This is esp--cially important in tow-fre-
quency instruments using large coils. This paper explains in detail how to calcu-
-ate demagnetization coefficients of such cores. Analytic equations used for solid
core design are modified to account for cavity effects. Curves based on these
equatlons are graphed to show the relationship between various design parameters.
Several examples are considered where the use of these parameters is made and the

computed results are tabulated. In the case where magnetic permeability of the ma-
terial approaches infinity, the demagnetization coefficient is a function of only
cavity size and the relative length of the cylinder. Orig. art. has' 4 figures, I

chosen for its low noise properties and the rest of the
amplifier consists of three P6A's in cascad.e. The base
currents in these stages are stabilised by thermistors.
The basic circuit of a compensated stage is that of
Fig 3 while Fig 4 shows the behaviour of the circuit
over the required temperature range. The dotted curve
on this graph shows the uncompensated performance.
Fig 5 shows the complete circuit of the instrument
including component values. The instrument error-3 for
three inputs 1 mv, 3 mv, and 10 mV, are shown in Figs 6
and 7 for variations in supply voltage and operating
temperature respectively. The input resistance is
1+ megohms, the zero drift is not worse than 20 )a V per
hour, the maximum sensitivitY is 10 F V , the current
Card consumption is lo mA, the dimensions of the instrument
2/3 are 235 x 155 x 115 mm, and its weight is 3 kg.
