A dry sprinkler includes a flexible tube section that maintains a pressurized fluid, such as a liquid antifreeze solution, between a first end and a second end. A first seal prevents fluid from a supply line from entering the flexible tube section. The first seal is maintained in a sealed position by a pressure of the pressurized fluid. A sprinkler head is coupled to the second end of the flexible tube section, and includes a frame, an output orifice, a deflector, a second seal that seals the output orifice, and a thermally responsive element configured to maintain the second seal in a sealed position when the thermally responsive element is in a non-responsive state. A differential pressure controller maintains a ratio between the pressure of the pressurized fluid in the flexible tube section and a pressure of a supply fluid in the supply line to at least a certain ratio.

The invention relates to a method for producing alkylene oxides by reacting an alkene with an arene oxide, pyridine-N-oxide, and/or pyrimidine-N-oxide, preferably an arene oxide and/or pyridine-N-oxide, in the presence of a catalyst in a first reactor, wherein the catalyst comprises a metal and/or a metal salt, and the metal is copper, silver, and/or gold. The metal salt comprises chrome, iron, cobalt, and/or copper cation(s), and the reaction is carried out in the absence of oxygen or an oxygen-containing gas mixture.
