Abstract: A foam extinguishing system with a fluid supply for providing a pressurized initial fluid, a pipe system in fluid-conducting connection with the fluid supply, the pipe system including a proportioning device with a foam proportioner and a foam agent reservoir for producing a foam agent fluid mixture by proportioning a foam agent from the foam agent reservoir the into the initial fluid for filling the pipe system with foam agent fluid mixture, and at least one extinguishing foam outlet for discharging the foam agent fluid mixture in a protected area. The foam extinguishing system further includes a filling device in fluid-conducting connection with the pipe system. The filling device including a filling valve and a filling supply for supplying a filling foam agent fluid mixture. A method for ensuring the functionality of the foam extinguishing system and for commissioning the foam extinguishing system is provided.

Abstract: The invention relates to a component (1, 1?, 1?, 1??, 2) for a fire protection system, in particular a fire extinguishing system having a housing (11, 21). In accordance with the invention, at least one nozzle (10, 20, 3, 3?) for dispensing extinguishing fluid onto the component (1, 1?, 1?, 1??, 2) is arranged on the housing (11, 21) or in the vicinity of the housing (11, 21), the nozzle (10, 20, 3, 3?) being connectable to a supply of extinguishing fluid.

Abstract: Described is a method for the production of pure or mixed metal oxides, wherein at least one metal precursor that is a metal carboxylate with a mean carbon value per carboxylate group of at least 3, e.g. the 2-ethyl hexanoic acid salt, is formed into droplets and e.g. flame oxidized. The method is performed at viscosities prior to droplet formation of usually less than 40 mPa s, obtained by heating and/or addition of one or more low viscosity solvents with adequately high enthalpy.
