PATENT OFFICE.

The present invention relates to a

Fire extinguishing procedure, which differs from the procedure according to patent 291380 only cooled water vapor is used as extinguishing agent.

With further attempts it turned out that one was already a very effective extinguishing of fire when one is pure. cooled water vapor without the addition of gases such as carbon dioxide, Nitrogen, sulfuric oxide, etc., used as extinguishing agents. For fires in living rooms, department stores etc. has the use of an extinguishing agent, consisting of a mixture of

! ■ 5 chilled water vapor and those mentioned above Gases have the disadvantage that the furniture in the apartments as a result of the chemical effects of the added gases strongly attacked or with prolonged exposure becomes unusable for further use. On top of that are these gases, like carbonic acid, Sulfur dioxide, etc., poisonous, so that they also affect those involved in extinguishing the fire Have a harmful effect on people or restrict their actions.

The devices for erasing can also be used here exactly as in the patent 291380 solion in the Apartments are provided, d. H. nozzles are attached at suitable points, from which the cooled steam can escape. So you will z. B. the nozzles in Schii'fskajüten in the ! Frames on the ship's walls or on the ceiling. ! attach, or you provide the container yourself, [in which the extinguishing steam is generated at suitable points in the rooms. Of course the facility can also be set up to function automatically by e.g. B. special valves are arranged, which open themselves at a certain temperature and allow the extinguishing steam to escape.

On the accompanying drawing is an extinguishing device, for example on Schüfen shown.

Between the exit point of the steam and the water, on the side of the ship's wall or ceiling facing the cabin, a sieve d is provided through which the cooled water vapor forming inside the ship's wall or ceiling can escape into the cabin space. Here, the steam expands and fills the room with a mist that creates the

extinguishes the fire that has broken out. The steam to be subjected to cooling is taken from the ship's boilers, from which a network of pipes branches out over the entire ship, and the required water is sucked in from reservoirs or from the fairway itself. Since z. B. 20 kg of steam of 16 atmospheres pressure with about 850 kg of water produce fog clouds of cooled water vapor, which can fill more than 1000 cbm of space per minute, so in 3 to 5 minutes the strongest fire can be in this way by means of cooled water vapor in rooms of the extent mentioned above can be deleted. It is therefore advantageous to install such extinguishing containers in different departments of the ships, factories, warehouses, etc. and initiate the extinguishing activity from a central office. As noted above, this extinguishing process does not endanger human life, nor does it destroy goods or home furnishings. In large rooms, exhaustors or pumps can be used to increase the extinguishing effect, for the purpose of causing the cooled water vapor to be introduced quickly into the burning rooms. The device shown in the accompanying drawing will .sich not only for ships but also particularly suitable for oil factories and flour mills in order to be able to quickly fill the various rooms with cooled water vapor and thereby prevent explosions. The perforated water pipes can be clogged with easily fusible alloys. Since the outflow openings of the water and steam inflow are opposite each other, the opening of the water inflow can take place through the tensioned steam, which offers a great guarantee for the inactivity of the device and furthermore excludes,
