ABSTRAM During the tooting of electrical equipment in rooms sub-
ject to the danger of explouion the usual teat methods
cannot be applied, because spark and arc formation must
be avoided. The All-Union W.entific Research 2nRtttute
of Aocident Prevention in the Oil Industry has dieveloped
special methods and equipment for electrinal tests under
these conditions. The testing of electrical equipment by
means of a megohm-moter ia carried out In such a way that
the device to be tested is completely assembled with switcaes
and starters, etc.in "on" position. The measuring is done
outside the room. If the measured resistance in below the
admissible value, every part of the installation is sepa-
rately measured. The application of a konotron to cables
is especially dangerouu because of the possibility of inten-
Card -1/4 sive spark and are formation. The kenotron should be

established at one end of the cable in a safe room. New
equipment has been developed which can be uned for testing
10 kv cables in dangerous rooms, applying a toat voltage
of 30-40 kv. A ventilator is installed at least 26 m
outside the danger zone and connected by means of a tube
with the junction box of the cable around which a ca5ing
is made. Within the sleeve connecting the air tube with
the casing a blocking device with a disc is iniitalled.
This disc is-operated by air flow and closes the contacts
and the coil chain of the relay RE-218 which in turn opera-
tes the kenotron (Figure 2). A cable with a cross sect4on
of 2 x 1-5 mm 2 is laid within the air tube to the contacts
in the sleeve. If the insulation of the cable is damaged,
there is no danger. Connecting the leads from the venti-
lator to the air tube is done by means of a current lead
(Figure 3). From the current lead a tube cable with a
cross section of 2 x 1.5 mm2 is laid to the control desk
(Figu7e 4). The automatic device consists of a -time re-
lay RE-218, the insulator OA-35 of 35 kv, and the ground-
Card 2/4 ing rod (Figure 2). The control desk consists of a two-

pole switch for switching the device on and off, & button
for switching on the kenotron type KU-1, and a par-el with
terminala for connecting the automatic circuit-breaking
device, the current lead, the kenotron, and a 220 v wire
from the main electric line (Figure 4). The ventilator
supplying the air should have a capacity of 50 m3lh at a
pressure of 40 kg/m2. The usual type of vacuum cleaner
may also be used. The ohecking of the grounding aad t,e
neutralization of electric installations consists usually
in the measuring of the resistance of the grounding and
of the leads of the grounding or neutralization. The
measuring is done by a grounding-meanuring device or a
double bridge. This method of measuring has the drawback
that the resistance caused by the connection of the cramp
and the measured object Is measured as originating from
the object. It is also shown that currents of 25-30 ma are
capable of exploding explosive.,iapor-air and gas-air mix-
tures. It was found necessary to develop an explosion-
proof cramp. Thia cramp is used for connecting the wires

shown in Figures 6 and 7. It consiats of a screw with a
chamber. In the chamber there are 2 mobile and 2 immobile
contacts for the current and potentia wires. The chamber
has a displacement volume of 0,175 eml. If there is a
spark during connection the volume is so small that e-en
a mixture of hydrogen and air is not dangerous. Th? minor
explosion does not'spread outside. The measuring bridge
is installed at least 20 m outside the danger areas The
bridge is switched on after the cramps have been installed.
Grounding resistance is measured by means of the device
MS-07. This device muat also be installed 20 m outside of
the danger zone.

TITLE: On the Problemo luggishness of the Photo-conductive Tubes
of the Vidicon e (K voprosu ob inertsionnosti foto-

PERIODICAL: Radiotekhnika I Elektronika, 1958, Vol 3, Nr 12,
PP 1501 - 1515 (USSR)
ABSTRAM -The inertia observed in photo-conductive tubes is of two
kinds* The first type of inertia is usually ascribed to
the incomplete disoharge of a picture element by tne
electron beam, while the second is due to the relaxation
of the photo-effect in the material of the target. The
inertia effects were investigated experimentally and the
results of the experiments and their interpretation are
given in this paper. The equipment used In the experiments
is shown In the block schematic of Figure 1. The basic
un.~.' of the equipment was an amplifier, comprising a
balanced input stage, a modulator and oscillator operating
at 110 kals, an AC amplifier and a phase detector. The
Investigated samples were in the form of glass plates which
were coated with a transparent layer of platinum and then
given a coating of antimony 8ulphide. The samples were
placed in a special holder Bo that the surface of the semi-

conducting layer was in contact with a drop of mercury,
which served as an electrode. The platinum layer was
used as the second electrode. The sample was illuminated
through the glasso In order to investigate the relaxation
.of the photo-conductivity, the samples were illuminated
by regiilar light pulses having a frequency of 1 cps. The
resulting curves of the increase and fall of the photo-
current are given in Figure 2. The experimental points
shown in the figure were talcen by the partial time method
(Ref 12); the curves correspond to the illuminations
of 100 Lux and 25 Lux. Further experimental results are
given.in Figure 3. which represent the ohaiging and dis-
charging currents of -the target; the full curves were
taken in complete darkness, while the dashed curves were
measured at an illumination of 50 Lux. From these
experimental data, it is concluded that the photo-conductive
target can be represented by an equivalent circuit connioting
of a two-atage RC network. This is ahown In Figure It.
The operation of the target can be simulated b either of
the two equivalent circuits shown in Figures The

the yet K, simulates the switohing, while K2 simulates
the illumination of a picture element (increase in con-
ductivity). This circuit comprises also resistance r
which represents the internal resistance of the beam, and
an RC network which is switched on for duration T, and
switched off for a time T2; T, and T2 represent the
switching time and the duration of a frame, respectively.
The operation of the photo-conductive tube can be
represented more accurately by the second circuit of
Figure 6, which consists of two RC networks. By employing
the first cirnixit or Figure 6, it can be shown that the
signal produced by th.) tube at the end of the n-th
switching cycle is gen by Eq (11) where the quantities
p and 'r are defined by the equations on p 1508. When
n-c~o , the sionl 'reaches a stationar-y value which Is
expressed by Eq Ti2a,. The switching inertia of the tube
can be defired as a ratio of the signal after the n-th
Card 3/5 cycle to th!-1 stationai-j si&-ial and this is expressed by

On the Problem of Sl-., giakness of the Phtto-conductive Tubes of the

Eq (13). The same type of analysis can be done for the
second circuit of Figrtre 6 but the Yrathematic3 becomes
ve17 involved. It is sh3wn, however, that the value cf
the stationary siUnal to given by Eq (16), while the

The parameter in Eq (17) is defined by Eqs (14). The
nudber of cyiAes ixeceaaax-j to reach tl-he stationary value
of the signal ean be approx1mately exprensed by Eq (20).
This equation was empl(,yed to represent thE. transient
proceSSe8 as a fviiction of the n1mber of cycles; the
results are shcwn graphically in Figures '(; the first
cuinve corresronds to the case when the illumination results
in an increase of the space eharge, while the second cuz-;9
corresponds to the decrease in the space charge. These
results were confirmed experimentally by means of a model
consisting of a two-stage RC network, furnished with the
necessary switches; the curve obtained from this model
are shown in Figure 9. From the experimental results
obtained, it is concluded that the transient processes in

PERIODICAL: Koks, i Khimiya, 1957, Nr 79 pp426-30 (USSR).
ABSTRACT: An investiEAtion of various production factors on -the
physico-mechanical properties of coke was carried out in
1953 on the Kharkov Coke Oven Works. In addition to the
standard method of testing (the weight of coke left in the
drum and the proportion of 10-0 mm fraction in the fines
formed) methods proposed by Lr4hIN, TsNII chormet. and IGI AN
SSSR were also used. The material collected is used by the
authors to compare the results of the individual. tests in
order to choose the most suitable testing -method. No des-
cription of testirZ- methods is given. In the w:perimental
coking the changes in the coal blends used were mainly dir-
ected to a partial replacement of couls K andna (in short
,Supply) by coals V and A . Blends'with additions of coke and
anthracite fines were also tested. Cokinc. was carried out in

were also tested. The results indicating the influence of
the composition of coal blends, degree of crushing, method
of charging and coking conditions on the coke quality are
given i:p Tables1p 2# 3 and 4 respectively. It was found
that each method of testing coke gives different results
for the inclividual quality indices which makes the compari-
son of the coke quality difficult. Changes in -~.he oomposi-
tion of coal blend, methods of preparation and ookimg con-
ditions cause a regular change in a number of coke quality
indices in opposite directions. Indioes of the amount of

ABSTRACT: A brief ac.want is givor. of a method In whic7a wushed and
crushed wsairfly-1,aking coal c-ha7g-9 is pratreated at 300-
35000 -with raw gas formed �n coking. Matter condensing
from the gas Impro,%-99 the cok-ing, properties of the charge.
The method was tested on a laboratory scale In a two.-
chamber retortq 'JI-he lower chamber containing coal whAAch
was cokad at 9200C, The gas produced passed through the
upper ?,hamber whiah Qontained the test coking charge. The
results (Table) showed that thG pre-treatment improved the
' coke properties. Thq pr6-treatment was also found to
Card 1/1 increase the deii3ity of the charge. There is 1 table and
