DEVICES FOR AUTOMATIC LAUNCHING OF FIRE EXTINGUISHERS BY THREE METHODS, AND TWO THEORIES:A- ELECTRIC MAGNETIC FIELD, (12 VOLTS 1.0 AMPERE) B- HYDRAULIC POWER CONTROL BY USE VOLATILE FLUID, PROVIDED WITH ALARM CIRCUIT(MINIMUM 1.5 VOLT) THE FIRST THEORY: THIS DEVICE MAKES THE FIRE EXTINGUISHER STORAGE PRESSURE (DRY POWDER, FOAM-GENERATION&CO2) WORK AUTOMATICALLY BY AN ELECTRICAL SIGNAL FROM A CONTROL PANEL THROUGH A THERMOSTAT OR FIRE DETECTIVES. THIS SYSTEM WORKS FOR ALL KINDS OF FIRE EXTINGUISHERS SUCH AS POWDER, FOAM, INERT GASES (E.G. CO2) AND FOR ALL OTHER PURPOSES. IT CAN ALSO BE USED FOR CARS AND OTHER VEHICLES. THE SYSTEM CAN BE MODIFIED TO SERVE IN PETROLEUM PLATFORMS, AIRPLANES ETC-.THIS DEVICE USES 12 VOLTS 1 AMPERE. THE IDEA OF THE DEVICE IS TAKEN FROM THE THEORY OF MAGNETIC FIELD WHICH LEADS TO THE OPEN AND CLOSE THE HEAD VALVE OF THE FIRE EXTINGUISHER. MAKES IT MOVE WHEN THE ELECTRIC SIGNAL IS ON. THE OTHER THEORY: INSTEAD OF USING MAGNETIC FIELD, A THERMOSTAT IS USED TO MOVE THE MAIN LEVER TO PRESS THE MAIN VALVE OF THE FIRE EXTINGUISHER. A VOLATILE FLUID THAT EXISTS IN THE SENSING BULB IS CHANGED FROM LIQUID STATE TO GAS STATE AND ITS PRESSURE INCREASES DIRECTLY WITH RESPECT TO ITS TEMPERATURE. BY THESE WAYS, ALL TYPES OF FIRE EXTINGUISHERS CAN BE MODIFIED TO WORK AUTOMATICALLY. THIS DEVICE CAN BE CONNECTED WITH FIRE FIGHTING SYSTEM IN LARGE AND IMPORTANT ENTERPRISES. IT SUITS ALL SIZES AND TYPES OF FIRE EXTINGUISHER. THE OTHER IMPORTANT ASPECT OF THE DEVICE THAT IT IS VERY CHEAP TO BE PRODUCED AND CAN BE ALSO DOMESTICALLY MADE
