(suspension) on wheels so it can move on 
the road.
	Fourteenth:	The device weight is 10 Kiligrams and with batteries 
18 Kilograms.
2. 	Working Principles:
The device depends on the principle of measuring light intensity.
When dripping the moistened reagents on the detecting tape which 
is contaminated by air, a chemical reaction takes place and a 
colored spot appears on the tape.  
The intensity of the color on the tape (the amount of darkness on 
the tape) is in direct proportion with the poisonous material 
concentration in the air, the intensity of the color also is 
influenced by other factors (heat, air absorption rate by the 
tape, the drop size...etc.).
When the device works the light falls from the source onto the 
tape then is reflected from the tape to the photoelectric cell, 
causing the photoelectric cell to light and thus expressing the 
photoelectric block of the device.
The photoelectric block works when enough darkening happens to the 
photoelectric cell, and that happens when the tape becomes dark as 
a result of changing the light filter when calibrating the device.
When the photoelectric cell operates it sends an audio and optical 
signal through the electronic block. The device works continuously 
by pulling the air from the moistened tape



during a limited period of time (4 minutes and 30 seconds), 
automatically after that the tape pulling unit changes the 
moistened part of the tape with the dry one and moistens it with 
reagents while the tape is moving. Therefore a complete cycle of 
the device is approximately 4 minutes and 30 seconds. During this 
time, if there is any poisonous material in the air existing in a 
concentration equal to or more than the sensitivity of the device, 
the device will give the signals. The time of the signal interval 
is dependent on the poisonous material concentration. For example, 
if the concentration is low the signal will be sent two to four 
minutes apart. But if the concentration of the poisonous material 
is high the signals will appear within the first minutes of the 
device cycle i.e. one minute apart. 
Detecting the radiation takes place by using a gaseous gauge type 
When radiation exists electric currents will turn on the audio and 
optical signals. The device detection for radiation for radiation 
is completely separate from the device detection of the poisonous 
material. Both the radiation detection cycle and the chemical 
detection cycle are completely separate.

A. 	The Gas Line:
	Figure number 1 shows the air passage through the gas line. 
	The air is pulled from the atmosphere to the device by a 
rotating pump (10) through the inlet opening on the cover 
of the device. After that the air will pass through the 
protective gasket (4) which contains filter (6) type 
(Latin symbols) and the chlorine -treated gaskets (5), 
then through the air amount gauge (3). After that the air 
goes through a reaction chamber (7) which is considered a 
part of the photoelectric block (2). 
	In the reaction chamber the reagent coming from the dropper (1) 
on the detection tape (11) absorbs the air and goes 
through the precipitation tank (8) in which the drops and 
the reagents are mixed together and go to the absorbent 
filter (9) through a flexible tube. The filter protects 
the pump from the remains of the poisonous material and 
the reagents which is carried by the air currents. The 
air is expelled from the filter to the inner cavity of 
the device by pump (10). 



	Figure Number 1: The Gas Line
The following are the parts of the gas line: 1 the dropper, 2 the 
photoelectric block, 3 the air amount measuring gauge, 4 
protective gaskets, 5 chlorine treated gaskets, 6 filter type, 7 
reaction chamber, 8 precipitation container, 9 absorbent filter, 
10 rotating pump, 11 detecting tape. 

B.  	Electric Cycle:
	Figure number 2 shows the electric circuit.
	The electric circuit contains the following circuits: The 
poisonous material detecting circuit, the device control 
circuit, the radiation detection circuit and the voltage 
altering circuits. 



	First: 	Poisonous material detection circuit:
		Includes an active photoelectric cell (Cyrillic text), 
a reference photoelectic cell (Cyrillic text), 
lighting bulb for the photoelectric cells, 
(Cyrillic text), valve (Cyrillic text), relay 
(Cyrillic text), yellow light bulb (Cyrillic 
text), audio signal (amplifier) (Cyrilic text).
		When the device operates a light beam falls from the 
light bulb (13) (figure number 6) on the 
detection tape. The light is then reflected from 
the tape through the light filter (4) to 
illuminate the active photoelectric cell (14). 
The standard photoelectric cell (1)is 
illuminated by the same light bulb through the 
transparent glass (15) and the light filter 
		The springs of the separators (shields) (2,16) are 
fixed so that the light beam falling on the 
photoelectric cell is always less than the light 
beam reflected from the moistened tape and 
falling on the active photoelectric cell (in the 
absence of the poisonous material spots on the 
		Through the above mechanism a negative voltage is 
formed on the valve (Cyrillic text) (figure 
number 2) which leads to preventing electric 
current from going through (closed valve).
		If poisonous material exists in the air, orange color 
spots are formed on the tape at the air suction 
point. That will lead to darkening the active 
photoelectric cell, and as a result a change in 
the photoelectric unit of the device and an 
increase of the voltage on the valve lattice 
causing it to glow. 
		Since the voltage increase on the valve lattice is in 
direct proportion with the darkening of the 
active photoelectric block (darkening of the 
tape) and since the glow voltage is a constant 
amount for the valve, that means that the glow 
will take place when there is a complete 
darkening on the tape. 



		To neutralize this darkness (lack of light) light 
filters are used for adjustment (8 and 9) 
(figure number 6). One of them works when the 
temperature is between 30 and 35 degrees 
Centigrade, and the other works when the 
temperature is between 35 and 40 degrees 
Centigrade. These two filters are used to adjust 
the device when preparing it for work. 
		When the valve glows the current going through it will 
operate the relay (Cyrillic text) (figure number 
2), the relay then is connected automatically 
through connection points 4 and 5. The divided 
dual valve is used to return the negative 
current back to the valve (Cyrillic text) 
through the relay (Cyrillic text) and the 
		When operating the relay (Cyrillic text) it connects 
points 6 and 7. Condenser (Cyrillic text) 
discharges the time relay to 7 volts (if it was 
charged to that amount) through resistance 
(Cyrillic text) and the battery (Cyrillic text). 
At the same time contact points 4 and 5 connect 
the relay supply circuit (Cyrillic text) and 
operate the latter.
		Through contact points 4 and 5 of the relay (Cyrillic 
text) voltage reaches the yellow light (Cyrillic 
text) and to the connecting points (Cyrillic 
text) to the transferred signal block. As a 
result of disconnecting points 3 and 4 the 
charging process of the condenser (Cyrillic 
text) will stop. Through the connecting points 6 
and 7, resistance (Cyrillic text) of the relay-
charging circuits is connected to resistance 
(Cyrillic text). 
		When operating the relay block (Cyrillic text) 
connecting points 7 and 8 are separated and when 
they are separated the negative circuits of the 
valve (Cyrillic text) are broken. That would 
lead to the production of another glow and would 
connect points 4 and 5 and produce electric 
supply to the audio signal. 
		After that the relay block (Cyrillic text) is closed 
when changing the circuit by contact points 7 
and 8 of the relay (Cyrillic text) or manually 
by pushing the valve (Cyrillic text) button. If 
order to increase the stability of the light 
block of the valve lattice (Cyrillic text), the 
ground should be connected through the condenser 
(Cyrillic text) voltage. 



	Second: Device regulation circuit:
	Includes the time relay, the regulatory relay (2 - P sub 1), 
circuit alternator button (3 - KH sub 6), electric engine 
(3 - M sub 2) for the tape pulling unit and lights 
(Cyrillic text) to test the cycle change. 
	The time relay block consists of valve (Cyrillic text), 
resistance charge (2 - R sub 1 and 2 - R sub 4), charging 
capacitor (2 - C sub 1) and the controlling resistance (2 
- R sub 2). Condenser (2 - C sub 1) is charged when there 
is no signal for poisonous material through resistance (2 
- R sub 4) to the glow voltage of the valve (Cyrillic 
text) in a time of 4 minutes and 45 seconds. 
	When the poisonous material signal appears, resistance (2 - R 
sub 4) is connected with resistance (2 - R sub 1) as 
explained before. As a result fixed time R sub C (to 
charge condenser (2 - C sub 1)) decreases to 
approximately one minute. 
	When the charge of the condenser reaches the voltage necessary 
for the valve (Cyrillic text), it glows. 
	The relay (2 - P sub 1) operates using the negative current of 
the valve and connects points 6 and 7 automatically. And 
when points 4 and 5 of relay (2 - P sub 1) are connected 
the remaining charge of condenser (2 - C sub 1) is taken. 
The voltage is sent through points 6 and 7 of the relay 
to the electric engine (3 - M sub 2) to the green light 
(Cyrillic text) and to socket (Cyrillic text) for light 
(Cyrillic text) of the transferred signal block. Through 
the electric engine work period by the handle a 
consecutive closure of the key at the beginning and when 
shifting the lower key (3 - B sub 4) the negative circuit 
of the valve (Cyrillic text) is broken to avoid false 
	The power supply circuit of the electric engine (3 - M sub 2) is 
connected to the signal lights (Cyrillic text) and 
(Cyrillic text) in the case of presence of poisonous 
	After a short period of time when changing the upper key (3 - B 
sub 5) the voltage is disconnected from relay (2 - P sub 
1). After that the lower key (3 - B sub 4) returns to its 
original position and breaks the power supply circuit to 
the electric engine (3 - M sub 2) and lights (Cyrillic 
text) and connects the power supply circuit of the 
negative pole of valve (Cyrillic text) the electric block 
returns to the original condition, and a new working 
cycle starts.



	In the absence of poisonous material, the normal working cycle 
of the device is 4 minutes and 45 seconds approximately. 
When the poisonous material signals appear, this time 
becomes approximately one minute (because of the decrease 
of the fixed time P sub C of the condenser charging 
circuit of the time relay condenser) after that the 
circuit is exchanged.
	When necessary the working cycle can be changed manually by 
pushing button (3 - K sub H6) which directs the voltage 
to the regulatory stage (2 - P sub 1). 
	The divided dual valve (Cyrillic text) will cause the return of 
the valve current (Cyrillic text) through the battery. 
	Radioactive material detection circuit
	The circuit includes the gas gauge (Cyrillic text) and the 
electronic amplifier of the semiconducting valves 
(Cyrillic text), the lights (Cyrillic text) and the audio 
signals (3 - 3B sub 1). 
	In the case of the presence of radiation in the air an 
intermittent charge affects gauge (Cyrillic text) and an 
alternate current goes through the gauge circuit. With 
the aid of the identical electric transformer (1 - T sub 
P2) the small alternate current at the semiconducting 
valves (Cyrillic text) to a constant current enough to 
operate the relay (1 - P sub 1). 
	Using connecting points of the relay 6 and 7 the light signal 
supply circuit (Cyrillic text) is connected. And by using 
connecting points 4 and 5 the audio signal supply circuit 
(3 - 3 B sub 1) is connected, the necessary sensitivity 
of the radioactive detector is arranged by the changing 
resistance (1 - R sub 4). 
	Batteries (Cyrillic text) are used as a power source for the 
	The following units are supplied with power directly from the 
battery: The valve glow unit (Cyrillic text), the 
photoelectric cell light (Cyrillic text), spotlights 
(Cyrillic text), transferred signal block lights 
(Cyrillic text), consumption gauge light (Cyrillic text) 
which is opened by button (3 - K sub H2), light (Cyrillic 
text) which is necessary for night operations and which 
will be turned on by button (3 -B sub 3), electric engine 
(3 - M sub 1) of the rotating pump, electric engine (3 - 
M sub 2) for the tape pulling unit. 



	The voltage of the batteries is tested by volt meter (Cyrillic 
text), by connecting it with the different circuits by 
three buttons.
	When pushing one of the three buttons (2K sub H4, 3K sub H3, 3K 
sub H1) the volt meter measures the voltage of light 
(Cyrillic text) and the valve glow (Cyrillic text) and 
also in general it measures the voltage of all the 
batteries. Resistances (3 - R sub 2, 3 - P sub 1) to 
protect from shortage when pushing two of the three 
buttons at once by mistake. 
	Switch (3 - B sub 1) is used to operate the device and supply 
the voltage. Resistance (3 - R sub 3) is used to regulate 
the pump production. The photoelectric cells, valve 
(Cyrillic text) time relay, radioactive detection 
material, and audio amplifier is supplied with 
electricity from the batteries by the voltage 
	The voltage transformer circuits: 
	Include the generator block, the trivalve (Cyrillic text), high 
voltage rectifier. At the high voltage coil of the 
electric transformer (1 - T sub P1) the low voltage 
increases at the generator block and rectifies by the 
silicon dual valve (Cyrillic text). The rectified voltage 
is filtered through condensers (1 - C sub 4, 1 - C sub 3) 
and resistance (1 - R sub 5) then settles between 380 and 
400 volts using gas stabilizer (Cyrillic text). 
	Resistance (1 - R sub 5) is usually chosen based upon the amount 
of the rectified voltage. The first section of 
resistances (1 - R sub 9 /1 - R sub 6) from which 
different voltages will be taken to feed the following 
blocks: 400 volts are sent directly with regulator 
(Cyrillic text) to supply gauge (Cyrillic text), from the 
resistance (1 - R sub 7) we take 110-120 volts to supply 
the negative pole for valve (Cyrillic text) and from 
resistances (1 - R sub 9, 1 - R sub 8) we take +40 volts 
and -40 volts to supply the photoelectric block (Cyrillic 
text) consecutively. Condenser (1 - C5) is considered the 
energy combining point in the negative pole supply 
circuit of valve (Cyrillic text). The energy combining 
process during the period in which the valve is blocked 
(closed) (The condenser charge continues for 
approximately 8 seconds). 



	When operating the photoelectric unit the valve glow and 
intermittent discharge of the condenser takes place 
through valve (Cyrillic text) and the relay coil 
(Cyrillic text). During the discharge period of the 
condenser the relay (Cyrillic text) operates and 
automatically connects as indicated above. Resistance 
(Cyrillic text) limits the negative pole currents within 
the limits. Condenser (Cyrillic text) is used to connect 
the resistance with the ground. 
	The voltage is taken from the second section which consists of 
the resistances (Cyrillic text) to supply the time relay, 
and voltage used to supply the valve charging circuits 
(positive pole) (Cyrillic text) is taken from resistance 
(1 - R sub 12), 150 volts is taken from resistance (R - 
14) to supply the negative pole of the valve (Cyrillic 
	Condenser (1 - C sub 7) ia considered energy combining point at 
the supply circuit of the valve (Cyrillic text) negative 
	Resistance (1 - R sub 16) will control the negative pole current 
of valve (Cyrillic text), while resistance (1 - R sub 2 ) 
will control the breaker work.
	To charge the batteries using the side methods, we use socket 
(Cyrillic text) and the dual valve (Cyrillic text) in 
case the device is not connected through the "wheel" from 
the side network, a counter supply for the device can 
take place through the dry battery from the side network.

B. 	Photoelectric cell block: 
	Figure number 6 shows the photoelectric cells.
	Light comes from light bulb 15) in two beams. The first one 
goes to the standard photoelectric cell (1). The other beam 
goes through the lens (12) to the detecting tape (5) then 
reflects of the active photoelectric cell (14). The light 
going to the standard photoelectric cell is regulated by the 
regulating spring (2) with the measuring wheel (3). When 
calibrating the photoelectric cell in the factory and when 
adjusting it after repair we use spring (16).
	The spring scale (2) is divided into two sections, ruler 
scale and manual scale. 
	One rotation by the manual scale (100 sections) equal one 
section on the ruler scale. To read the measure on the ruler 
scale take the left side of the scaled wheel. Each 
photoelectric cell is placed in a tight chamber.

	Light filters (4) and (17) in addition to their regular 
function (absorption of certain section of the light beam 
spectrum) are used for securing the retention. 
	In front of the standard photoelectric cell additional 
transparent glass (15) is fixed in order to reduce and insure 
equal light for the photoelectric cell.
	The photoelectric cell body is painted with a certain paint 
in order to avoid the effect of moisture on the photoelectric 
cell work. At the lower part of the photoelectric cell block, 
between the tight transparent glass (10) and the light filter 
(4) sits the upper parts of the reaction chamber, the 
analyzed air enters the upper parts of the reaction chamber 
through nipple (6). During the working time the device 
absorbs the air from the upper parts of the reaction chamber 
to the lower parts through the detection tape and combines 
with the reagent solution on the tape.  The lower part of the 
chamber is used to tighten the tape to the photoelectric cell 
	The entrance opening which exists at the lower part of the 
chamber is surrounded with three central protrusions which 
help to direct the tape to the photoelectric block and also 
help to reduce the air suction from the sides. 
	Also in the opening there is a cross shaped plate to prevent 
the tape from curving during air suction. During the tape 
movement the moving part of the chamber moves downward by a 
lever system releasing the tape.
	Between the condensing lens (12) and the protective glass 
(10) there is the light filter exchange block (11) with two 
levers to change the filters. The lower lever is used to 
regulate the photoelectric block of the device when the air 
temperature reaches 35 degrees Centigrade and the upper lever 
is used when the air temperature exceeds 35 degrees 
C. 	Tape pulling system:
	The regulator with the exchange rate of 1:337 (figure number 
5) is considered to be the main part of the system. The 
regulator operates the electric motor (Cyrillic text) which 
operates the tape pulling system and handles, this motor has 
two external axes. One is the main (57) and the other is 
small (58).



	On the main axis there are the following: 
	Tape tightening block (56), dropper operating rod (54), and 
the switch (60).
	When the main axis rotates handle (54) lifts the rods (59) 
upwards which operates the dropper and that in turn will lift 
the arm (18) which will enter at the dropper rod head. After 
handle (54) moves out away from the rod (49), the rod moves 
down under the effect of the pulsator taking with it arm (18) 
to the original position.
	The detecting solution drips on the tape, after that handle 
(56) will squeeze the tape tightening arm. Meanwhile the 
moving section of the reaction chamber moves down.
	Under the effect of the tape tightening wheel (31) the 
released detecting tape moves, and as a result the moving 
parts of the chamber move downwards for a distance of 16 
	The small axis (48) rotates the tape tightening wheel. The 
receiving wheel axis rotates through a friction device with 
teeth (59) on which the used tape is wound. 
	The friction device ensures the tape tightness at all times. 
Before shutting down the electric motor of the tape pulling 
system the tightening mechanism goes to its original position 
therefore the tape is tightened once again.
	Handle (60) is used to turn the switch which operates the 
tape pulling system.
D.: 	The Dropper:
	The dropper shown in figure number 7 is used to drip a 
certain dose of the reagent (0.15 approximately) on the 
detecting tape. 
	The dropper consists of: The body (3), the cover (2), the 
piston and the end of the dropper (12), with the hose (11). 
In the lower part of the dropper body there is a flexible 
gasket (7) which has a direct opening and the walls are 
exactly enough for the head of the piston, so if the head of 
the piston goes through the opening it closes it firmly. The 
gasket is fixed on ring (8) and between ring(8) and nipple 
(10) sits valve (9) which prevents air movement into the 
dropper when the piston moves up. The dropper piston consists 
of the bar (1), the director (4) which is mounted freely on 
the valve bar (5) and attached to ring (6).



	During the piston movement up the valve (5) opens the opening 
on the lower part of the director (4) and moves in the 
detecting solution under the piston.
	When moving the piston downwards valve (5) pushes the 
director by the pressure of the detecting solution underneath 
and that in turn will lead to pushing the solution underneath 
the piston. At the moment of closing the opening in gasket 
(7) using the end of the bar one dose of the detecting 
solution will fall. The drop is sent from the dropper by the 
hose (11) and ejected from the end of the dropper through 
opening (12).
E. 	Graduated Cylinder (measuring the drop size): 
	The cylinder is used (figure number 8) to measure the drop 
	On the cylinder there are four lines for different sizes of 
the drop. 
	The red lines (4 and 6) indicate the permissible size of the 
drop (0.13 to 0.17 milliliter) when using the device at the 
positive temperature, the black line (3) indicate the 
permissible size of the drop when using the device in a 
temperature between 0 and 30 degrees Centigrade, and line (3) 
indicates the normal size of the drop (0.15 milliliter) when 
preparing the device for work. 
	Opening (2) prevents the possibility of forming an air bubble 
when measuring the drop size and allows the trapped air to 
escape through it.

The pump consists of the electric motor (1), the body (2), the 
pump (3), the rotors (4), cavities (5), and the cup (8). 
The body (2) is connected with the electric motor (1) by four 
springs. The rotor rotates in a central chamber on the pump axis. 
This chamber is closed from the bottom by cover (7) and pressure 
nut (6). The rotating movement moves from the electric motor to 
the rotor by a pulsating connection. The pump works in an oil bath 
therefore the oil is poured in the cup until the line on the 
inside of the cup (1.5 to 2 milliliters approximately).

Note: The units are equipped with the device without adding oil in 
the pump therefore the cup should be filled with oil before using 
the device. 



F: 	Suction Filter:
	The suction filter (figure number 10) is used to purify the 
air from the remains of both poisonous material and reagents 
that can cause dirt and oxidation of the rotary pump. 
	The filter body (3) is filled with active charcoal (5) to 2/3 
of the volume. The rest of the volume is filled with dry 
silicon gel (4), the filter is covered with cover (1) and 
tightened by gasket (8). To avoid dirt in the air pipes and 
pump the accessories have to be changed every 100 working 
hours, these accessories are located between the two networks 
(2) and (6) including the cotton gasket (7) and the gasket 
(10) which is tightened by pulsator (9).

G. 	Air Volume Gauge:
	This gauge is used to measure the amount of analyzed air 
passing through the detecting tape (figure number 11). The 
gauge consists of a body (1) which is a cylinder made of 
"organic" glass and a cork (2). The two nipples (3) are 
connected to the body by springs. The air coming through the 
final opening of the body will raise the cork to a certain 
level and can be controlled by observing the cork level. When 
the air volume reaches 1.5 liters per minute the cork will 
rise up so that its upper level is equal to a line indicated 
on the body. 
	A light bulb (53) (figure number 5) is used to illuminate the 
device for ease of use. The light bulb is fixed on the inside 
middle panel of the device.

is considered to be the beginning of the gas line.
	(Figure number 12) Shows the compartment which is considered 
to be a moveable part (non attached). In it there is a 
special filter for smoke (7). There is also the chlorination 
box (5).
	The chlorination box consists of the bottom three which is 
attached to the nipple (9) on a hole by a nut (1) and a 
washer (2) which helps the accurate alignment of the part 
with the air entrance opening on the device cover (6) and the 
body (8).
	In order to secure the chlorination box with the bottom there 
is a rubber gasket (4). The compartment is connected with the 
air gauge by a short pipe.

4.	Conclusion. 
	The apparatus is painted from outside with a special paint 
which has a protective color. The serial mark is located on 
the apparatus, on the boxes, charges as well as on the 
movable indicator gadget. This mark consists of the following 
	1.	The symbol of the factory which made the apparatus.



	2.	The name of the apparatus.
	3.	The number of the apparatus.
	4.	The number of the class.
	5.	The year of production.

	The sign should be placed on the box, written in black 
letters and it should be water and smear - resistant. It 
should read as follows:

	ASB - (m) apparatus number .........class number........
	The following inscription should be also placed on the 
	Height.... Proceed with caution. Weight....
	Or it should have a name written in the middle (( Y  )).
	It is necessary to cover the apparatus with a cover made of 
nylon, 0.2 millimeters thick when it is supposed to be 
stored. The nylon will protect it before humidity. In order 
to absorb the humidity and the steam under the cover, we need 
to insert the cotton bags which contain about 150 grams of 
the silicon gel per bag. When the cotton bags are inserted, 
you should apply pressure on the cover to remove the excess 
air and seal the ends of the cover. The apparatus should be 
packed in a box to protect it and to transport it. 

	The entire apparatus with all necessary attachments include 
the following items:
	the apparatus itself, the charging box, the connecting wires, 
the detecting device, the replenishment parts, the 
operational record, the instruction and maintenance manual 
and the list of contents.
