Abstract: A fire-extinguishing device is furnished, wherein an aerosol is generated in a single container or in a plurality of containers by burning a solid extinguishing agent. The aerosol streams and flows into the area to be protected along a nondirect path through annular channels or directly through a sieve floor.

Abstract: A sprinkler for automatic fire extinguishing plants according to the dry system is furnished for rooms subjected to and endangered by freezing and frost. Such plants are furnished in particular in case of the presence of a suspended ceiling with downwardly branching pipe pieces. In order to adapt the downwardly branching pipe pieces to the prevailing construction conditions, the branching pipe pieces are furnished by two pipe pieces screwed to each other. The two pipe pieces exhibit a support body at the upper end and a sprinkler at the lower end. The two parts are connected via two rods or pipes, screwed to each other, to form the special sprinkler.

Abstract: A method and a device is provided for the discharge of a foam, in particular of a high-expansion and/or medium-expansion foam useful in connection with fire-extinguishing and the like. The foam is furnished with an antifoaming agent water mixture, is suctioned in by a fan blower and is disintegrated. The resultant solution is collected via a separator in a subsequently disposed collection container, and is further transported with a pump.

Abstract: The invention comprises a method and an apparatus for the waste disposal of light and/or medium and/or heavy foams employed in connection with fire extinguishing or the like. The foam is sucked in by a blower or the like, is disintegrated and in the following, is concentrated in a following container. The larger part of the air is thereby separated from the foam and the foam is reduced in a further-following separating stage to the volume of the initially employed foaming agent water mixture. The separating stage can be a centrifuge or a cyclone. Upon waste disposal of a low foamed heavy foam, this heavy foam is sucked up with a pump and in the following the pump is separated. In both cases following, the mixture is fed to a further waste disposal stage.

Abstract: The invention relates to a formation of a release element, where the upper end and the lower end of a cylindrical or conical glass tube are closed by means of inwardly directed plugs.

Abstract: The invention relates to a release element for sprinkler systems comprising a cylindrical tube, where the ends of the cylindrical tube are respectively hermetically sealed by melting to a plug, where provisions are disposed jointly with the closure piece and counter piece of the sprinkler, which only exert pressure forces onto the center cylinder-shaped tube portion of the release element.

Abstract: An individual source identification of several signal providers or pick-ups with closable contacts disposed in a twin-wire signal line, in particular for fire detectors in fire alarm systems. The signal pick-up system allows to distinguish actuation of individual sensors separately and apart from a short circuit formation. The fire alarm system also allows connection to automatic sprinkler devices. The fire sensor system is easy to install in that the individual settings of the individual detectors at a construction site are minimized.
