3, 1935. [Classes 9 (i) and 9 (ii)] [Also in Group XXXIII] Relates to the propulsion, by jet reaction, of rockets, vehicles, aircraft and the like. According to the invention the nozzles, through which the gases issue, have cooled walls and an opening angle which is greater than ...
The gun also has two spark plugs positioned in front of the nozzle, which are powered by a portable battery. To prepare the gun, the operator opens the ignition valve and presses a button that activates the spark plug. This creates a small flame in front of the nozzle, which ignites the...

This type of extinguisher contains and dispenses deionized water in a spray that is non-toxic and non-conductive. When discharged, water expels through a spray nozzle, making a fine mist curtain that cools the fire and reduces the oxygen feeding the inferno, thus suffocating it. Water ...
To take into account the effect of the flame-retardant in the gas phase, it was assumed that the additive reduces the rate of the global macroreaction of MMA oxidation: MMA + O2 -> Products, in accordance with the following formula: 𝑊𝑔=𝑘𝑔(1−𝛾𝑌TPP)𝑌𝐹𝑌𝑂exp(...
As the reaction accelerates of course the ions precipitate within the mix totality. The heat still keeps increasing for a while and can be measured by the kJ energy unit and perhaps it could be calculated as well. By Rado I’ve been looking for firebricks in Qatar but with no luck, ...
Because Halon 1301 inhibits the chain reaction that promotes the combustion process, it chemically suppresses the fire very quickly, unlike other extinguishing agents that work by removing the fire's heat or oxygen. Stored as a liquid under pressure and released as a vapor at normal room ...
Remember the four-word formula "shake, pull, hold and press" Shake: lift the fire extinguisher and shake it: pull out the safety pin of the fire extinguisher Hold: hold the nozzle and aim at the root of the flame Press: keep a proper distance, press the handle (4-5 meters in general...
When it comes to mechanical components of our robot, the ones which needed testing were the water tank with hoses and the nozzle. Since it was to be put on the platform next to electronics and circuitry, it was imperative that the system be sealed and there be no leakage. ...
The technique includes bursts of water from a fog nozzle producing small droplets into the hot gases. The purpose of this work was to experimentally investigate the effects of gas cooling. A total of 44 tests were conducted in an 1800x1200x1200mm room with an added fire room sizing 1200x...
