Abstract: The apparatus is located almost completely under the surface of the sea. The vacua in the de-aeration and the evaporation chambers are generated by a vacuum pump and are maintained by the effects of a pressure reduction device at the inlet for warm seawater and a lifting pump at the outlet for brine. The de-aerator and the evaporator are laid out as heat exchangers and penetrated by heating tubes, which are flowed through passively by warm seawater. The immersion tube forming the steam compartment which is suspended vertically in the sea serves as a condenser. The condenser is cooled passively by cold seawater. The attachment to the bottom of the sea is performed by a single point mooring construction via an anchor chain at an anchor weight. The elevation of the water production unit is controlled automatically by means of an air chamber and an air compressor.

Abstract: A process for stabilizing organosiloxanes containing SiOC-bonded radicals, by treating the organosiloxanes with compounds which scavenge hydroxyl groups, selected from (a) organic isocyanates, (b) compounds of the general formulaX.sub.m SiR.sub.n, (I)in which X represents a radical of the general formulaR.sup.1 COO-- (II)or a radical of the general formulaRR.sup.1 C.dbd.N--O-- (III)where R represents an optionally halogen-substituted C.sub.1 to C.sub.16 -hydrocarbon radical, R.sup.1 is the same as R or a hydrogen atom, m is 1, 2, 3 or 4, n is 0, 1, 2 or 3 and the sum of m+n=4, and mixtures thereof.
