Abstract: Fire protection device for gangways 3 between the coaches 2 of rail vehicles with a gangway 3 between coaches 2 of a rail vehicle, and a fluid-fed fire-fighting device. Effective fire-fighting with low weight is made due to the fact the fire-fighting device comprises a fluid mist nozzle 4 which delivers a fluid mist, whereby the at least one fluid mist nozzle 4 is arranged in such a way that the fluid mist is sprayed into the gangway 3.

Abstract: A cleaning system for a cooking range exhaust having a range hood, a backsplash, and an exhaust flue for exhausting cooking effluent is disclosed. The cleaning system can include a fluid delivery system constructed for partial placement within the cooking range exhaust. The fluid delivery system can include a hood spray conduit constructed for placement within the hood and comprising spray openings for directing a degreasing composition to the backsplash. The fluid delivery system can also include a flue spray conduit constructed for placement within or outside the exhaust flue and comprising at least one spray opening for directing the degreasing composition to an interior surface of the flue. The cleaning system can include a pump system constructed for conveying the degreasing composition from a degreasing composition source and through the fluid delivery system. A method of cleaning a cooking range exhaust and a self-cleaning exhaust system are also disclosed.

Abstract: The invention relates to a railway vehicle comprising a fire-fighting system having a supply container for extinguishing agent, a system of pipes, means for dispensing extinguishing agent, and a pressure-generating means. To improve the reliability of this system, it is proposed that the pressure-generating means be coupled to a compressed-air supply belonging to the railway vehicle, that a quiescent pressure can be generated in the system of pipes with the help of the pressure-generating means, and that a case of fire can be detected by means of a pressure drop in the system of pipes.
