Seventh: The position of the device is vertical and allows a slope of 45 degrees. (3) RESTRICTED RESTRICTED Eighth: Drop volume when temperature is between 20 + or - 5 and 40 degrees Centigrade equals 0.15 + or - 0.02 milliliter. But when the temperature changes from 20 + or - 5 to 30 degrees Centigrade, the drop volume becomes 0.15 + or - 0.05 milliliter.

Eleventh: The audio signal can be heard for 5 meters when the cycle is working on the same average as the engine. Twelfth: The device is completely isolated from dust and dirt. Thirteenth: The device is mounted on shock absorbants (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 (4) RESTRICTED RESTRICTED 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 CTC-5. 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). (5) RESTRICTED RESTRICTED 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. (6) RESTRICTED RESTRICTED 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 (17). 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 tape). 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. (7) RESTRICTED RESTRICTED 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 battery. 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. (8) RESTRICTED RESTRICTED 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 alarm. 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 material. 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. (9) RESTRICTED RESTRICTED 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. Third: 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 device. 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. (10) RESTRICTED RESTRICTED 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 transformer. Fourth 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). (11) RESTRICTED RESTRICTED 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 text). Condenser (1 - C sub 7) ia considered energy combining point at the supply circuit of the valve (Cyrillic text) negative pole. 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. 3. The technical description of the device: A. General structure of the device: Figures (3, 4, 5) show the general shape of the device structure.

Figure number 5: General view of the back side of the device panel (15) RESTRICTED RESTRICTED 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. (16) RESTRICTED RESTRICTED Figure number 6: Photoelectric cell block: Key: 1. Standard photoelectric cell 2. regulation spring 3.

Light filter (17) RESTRICTED RESTRICTED 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 block. 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 Centigrade. 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). (18) RESTRICTED RESTRICTED 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 millimeters. 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). (19) RESTRICTED RESTRICTED 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 size. 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. (20) RESTRICTED RESTRICTED Figure number 7: Dropper: 1.

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. (23) RESTRICTED RESTRICTED 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).

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. Figure number 11: Air Gauge 1. Body 2. Cork 3.
