ABSTRACT: Numerous methods of ore prospecting by means of alternating
currents of various frequencies are based on the assumption
that the electric and magnetic characteristics of the rocks,
and particularly the electric resistance, are independent
of the frequency. Laboratory investigations on this point
are contradictory. In this paper the results are described
of field investigations of the dependence of the specific
resistance on the frequency between 0.3 and 300 c.p.a. The
experiments were made with a current of periodic but-not-of

ABSTRACT- Under the direction of A.K. Tikhonov, the method of
el;etro-maenetic sounding is being developed in the Institute
of Physics of the Earth Ac.Sc. USSR (Institut Fiziki Zemli
AN SSSR) for the purpose of geological prospecting. The
obtained experimental material is described in a separate
report by the author of this paper, Ye.M. Ushakov and others
"Developmeub of the Technique of Bounding by Means of Alter-
nating Currents and Study of the Resolution Power of this.Type
of Prospecting", Institute of Physics of the Earth 1956. On
the basis of analysis of some of the obtained resuits, it is
concluded that sounding with direct current effected by means
of a system of spacings A between the metering circuits can
be substituted by frequency-sounding effected solely with a
single spacing between the metering instruments. The possi-
bility of using frequency-sounding is based on obvious physical
Cardl/2 considerations and has been -,b01**Wftd by various authors,

ABSTRACT: Some of the results are given which were obtained in
electromagnetic sounding of geomagnetic structures located
underneath intermediate nonconducting strata. The geo-
electric structure of the points at which the investigat-
ions were carried out was d6termiiied-according to the data
of supporting wells and according to soundings by means of
direct current carried out by various teams of Glavneftgeo-
fizika. The soundings described in the ;aper were obtained
in the neighbourhood of the supporting wells. The geologi-
cal conditions of the point are briefly described. There are
2 graphs and 1 Russian reference.

ABSTRACTs In order to make the output current wave shape of an
inverter as nearly sinusoidal as possible, the resistance,
inductance and capacitance of the load should be such
that its natural frequency is near to the forced
frequency imposed on the inverter by grid control; the
commutation conditions will then also be right. If
there is no need for the output current to be sinusoidall
in determining the commutating capacitance it is
necessary to investigate the current wave form in the
inverter loadj'see for example2 Fig 1. If the inverter
load current wave shape and the extinction time of the
Valve are.known, a value of capacitance may be chosen
Card such that the anode potential of the valve passes

1/3 through zero at the appropriate moment. However,
inverters are often required to operate over a very wide
range of frequencies ranging from hundreds of cycles t

hundredths of cycles per second. At very low frequencies
the current cannot be made sinusoidal by increasiLg the
capacitance of the commutating capacitor. In this case
the transformer connection of the inverters cannot be
used and the bridge circuit is used$ and it is then
possible to calculate the value of the capacitance from
analysis of the load current shape. This brief article
describes a method of estimating the value of the
commutating capacitance and the cathode inductance by
another method that requires information only on the load
-resistance and the voltage of the d.c. source. The bridge
inverter circuit with resistive load shown diagramm ti-
cally in Fig 2, is considered. Eqs ?1), ()+) and (5) are
derived from which the value of capacitance that is
.required for commutation may be calculated using Eq (6).
This capacitance is calculated without allowing for the
shuntingeffect of the load resistance which must be

from which the final value of the commutating capacitance

ABSTRACT: An apparatus and the method of its application is
described. The design of a receiving station is illustrated
in Fig 10 It consists of a DC amplifier I (Fig 2), a
cathode-ray oscillograph 2, whose screen is photographed
during the setting up of a tension AV in the receiver,
and a pulse generator 3 (Fig 3). The measuremeats
were carried out "In situ" and the curves of resistivity
as a function of time, p t), were determined (:Figs 4.
to 6). The analysis of e curves showed that by this
method a quantitative data of the geo-electric
properties in a given cross-section can be dete---mined,
This method can be very economical if a fast plottin

set. Measurements are made in two cycles -- operating and calibrat-
ing. During the operatin,,, measurement cycle current of set frequen-
cy enters the power dipole AB from the generator, and the current's
agiplitude is recorded. Impulses of the current's initial phase are
transmitted to the receiving set along an ultrashort-wave radio
channel. The signal received by the electric or magnetic dipole MN
is amplified and filtered from interference; then its amplitude

the phases of the signals received thereby remain unkn6wn, since
the amplification factor and the natural phase angle of the ampli-
fying-recording channel are not known. These-values are'determined
during the second.calibration cycle of measurements. This consists
of sending rectangular voltage of known amplitude with a frequen-
cy, strictly corresponding to that of the current in the dipole AB,
from the output of the.calibration apparatus to the input of the
amplifying-recording channel. The circuits are given together.with
a description of the arrangement and the performance of the Cenerat-
ing and receiving sets. The generator has a power of 33 kilowatts
and operates in the frequency band 0.04 - 250 cls. It is a thyra-
tron commutator and gives out alternating current, whose amplitude
and form depend chiefly on,the resistance of line AB, the capacity
of the commutating condenser, and the commutation frequency. The
generating set is.supplied from a gasoline A64-A/2,30 (AB4-b/230)
unit with a power of 4 kilowatts, a voltage of 220 v, and a fre-
quency of 50 c/s. The receiving set,- as is pointed out, must ensure
that the amplitudes and the phases can be measured very accurately
(3 and 1~.respeotively), Since the signal received is strongly com-

plicated by interference., a composite selective amplifier with a
wide controllable transmission band and a high (about 3 x 108) am-,
plification factor is used to amplify the low (of the order of un-
its and tens ofAv) reception signals and to filter them from inter-
ference. The chosen system of series filtration on aperi6dic.selec-
tive elements, distributed between several amplification stages,
and the choice of amplification factors allows the time of traii-
sients in it to be-reduced maximally. This is especially important
when operating on infralow frequencies. The amplitude and the phase
of the receiving signal are measured simultaneously by two mutually
controlling methods; by means of an indicating instrument and
through recording the-signal on the film of a loop oscillograph. It
is pointed out that tests of'thiB.station prototype have shown that
:it satisfies the requirements resulting from the method's theory
and from the practice of field experimental research. Z-Abstrac-

TEXT: The generator set-is intended for generating al",exmating
currents with a frequency of 0.04 to 250 c/s. current of up to 50
amp. is generated at an active load of 30 ohms. It is poi;sible to
get direct current of up to 100 amp.,by employiM a doubling air-
cuit. The frequency and amplitude stability equals 1% over the
whole range of 24 fixed frequencies. The equipment is moitnted on a
30,fi (ZIL) vehicle'in two sections -- equipmental and genorating.
The station's'outtit..,also.,includ,e's a special vehicle for winding
and unwinding the wires. Direot current from ft/1-95'(PN-45) genera-
tore is converted.into alternating by a thyratron commutator. The
thyratrbn commutator is a bridge circuit that guarantees almost

commutated current is substantially distorted as the fre~juency in-

A d.c. gasoline-set with a voltage of 220 v and a power of 4 kw

station is controlled from a panel. The work of this station in-
