Abstract: A fluid measuring or fluid control device has a housing the housing parts of which are fastened to each other by at least one screwed connection, in which a screw engages through an opening in a peripheral wall of the first housing part and is screwed into a threaded opening in the second housing part. An elastic seal is arranged between the housing parts. The first housing part has a first resting face, and the second housing part has a second resting face which are both in peripherally circumferential contact with the seal. The screw shank and an edge of the opening have cooperating frustoconical surfaces which are oriented such that the second housing part is displaced in the direction towards the first housing part when the screw is screwed into the threaded opening, the resting faces coming into contact with the seal.

Abstract: The invention relates to the preparation and use of polyfluoro-alkylsilanes of formula (I) 1

Abstract: Fluorinated benzaldehydes are obtainable in a simple and inexpensive manner and in significantly improved yields when chlorinated benzaldehydes are reacted with alkali metal fluorides at temperatures in the range from about 130 to 200.degree. C. in the presence of less than about 2 mol % of quaternary phosphonium salts, based on chlorine atoms to be replaced, at initial concentrations of more than 2.5 mol of the chlorinated benzaldehydes per kg of dipolar aprotic solvent. Fluorinated benzaldehydes obtained in this way can advantageously be hydrogenated with hydrogen in the presence of noble metal catalysts to give fluorinated benzyl alcohols.
