Abstract: A fuse device comprising a housing, at least two connection lugs, a connecting element between the connection lugs, and an actuator. The actuator moves the connecting element from a closed position, in which it connects the connection lugs, to an open position, in which it is disconnected from at least one of the connection tabs. A particularly well-conducting connection between the connection lugs and the connecting element, which can nevertheless be easily disconnected by the actuator, is achieved by the connecting element being interference-fitted between the connection lugs.

Abstract: A plant for producing chain-type ammonium polyphosphate from ammonium orthophosphate and phosphorus pentoxide in the presence of gaseous ammonia comprises a reactor having rotatable mixing, kneading and comminuting tools in its interior and a feed pipe for the solid starting materials, an introduction pipe for ammonia, a gas discharge pipe and a discharge line for the reaction product, all of which are flow-connected to the interior of the reactor. The discharge line of the reactor is also connected for material flow to a mixing apparatus. A discharge device, which is controlled by the power consumption of the drive motor of the reactor, is arranged in the discharge line.

Abstract: The purification of phosphorous acid which is formed in halogenations of hydrocarbon derivatives using phosphorus trihalides is carried out in the context of preparing phosphorous acid in a reaction zone by reacting a mixture of phosphorus trichloride and water which has been finely divided by means of steam at temperatures between 150.degree. and 200.degree. C. in the gas phase. In this process, the liquid reaction product drains into a concentrating evaporation zone which has a downstream first separation zone. Inert gas is introduced to the lower part of the first separation zone. A melt is withdrawn from the first separation zone into a crystallizing zone. The waste gases from the reaction zone are treated with a washing liquid in a second separation zone before being passed into the atmosphere. The washing liquid used is an aqueous solution of never-purified phosphorous acid, which can have been prepurified by hydrolysis and stripping.
