摘要: A flame-proof housing (10) of the protection type ex-d is made from two sheet metal blanks that are bent in a u-shaped fashion. They then are fitted into one another and subsequently welded together by means of a peripheral fillet weld without welding seam preparation. A large opening (28) can be provided on one side of the housing (10), which can be closed with a threaded cover or with a flat cover.

摘要: The invention relates to a polymer suitable as a dispersant, built up from A) 0-80 mol % of one or more monomers having the formula ##STR1## in which R.sub.1, R.sub.2, R.sub.3 and R.sub.4 may be the same or different and represent H or alkyl, B) 0-70 mol % of one or more monomers having the formula ##STR2## in which R.sub.5, R.sub.6 and R.sub.7 may be the same or different and represent H or alkyl and R.sub.8 is alkyl or substituted alkyl, and the alkyl group R.sub.8 may also be interrupted by --O-- groups, C) 5-50 mol % of one or more monomers containing a heterocyclic group having at least one basic ring nitrogen atom, or to which such a heterocyclic group is attached following polymerization, D) 0-10 mol % of one or more monomers containing one or more groups reactive to cross-linking or coupling, and E) 0-20 mol % of one or more monomers not falling within the groups A-D, the amount of monomers from group A together with monomers containing an acrylate group being at least 20 mol %, as well as organic salts thereof, and also to the use thereof.
