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： Stabilized perchloroethylene containing 0.001 to 0.1% by weight of N-alkylmorpholine, 0.001 to 0.01% by weight of alkylphenols, 0.0005 to 0.002% by weight of diisopropylamine, and 0.05 to 0.5% by weight of cyclohexeneoxide. By stabilization with the mixture of stabilizers, the perchloroethylene is stabilized to an extraordinary degree against attack by metals, particularly, decomposition through oxidation in contact with metals or metal salts, in some cases also upon exposure to light. A further improvement of the combined stabilizing action can be obtained by the addition of 0.005 to 0.1% by weight of epoxipropanol.
