    Abstract: Element, preferably in panel form, for use as thermal insulation, comprising …… a) a finely dispersed, pulverulant or fibrous substance, … b) a microporous covering and … c) a gas-tight and water-proof metal-free covering. …… The element is produced by drying the pulverulant or fibrous substance, if appropriate, introducing it into a microporous covering, if appropriate, compressing it, if appropriate, and then drying it, if appropriate. After that, the pulverulant substance with the microporous covering is introduced into a gas-tight and water-proof, metal-free covering. If appropriate, this gas-tight and water-proof covering is evacuated and sealed. … …

    Abstract: Macroscopic, spherical particles having a dia. 0.01-3.0 mm, a specific surface 0-10(3) m2/g, a specific pore vol. 0-6.0 ml/g and a bulk density 50-10(3) g/ltr are produced from known polymeric opt. crosslinked, sec. or tert. organosiloxaneamines NR2R', where each R is independently a gp. -R''-Si-(O-)3; R' is H, R, (cyclo)alkyl or benzyl; R'' is a divalent gp.; the free O valencies are opt. satisfied by metal atoms of bridging members. The particles are pref. produced by dissolving a sec. or tert. aminosilane NR1R2, where R1 has similar meanings as R and R2 has similar means to R', opt. together with a metal contg. crosslinking agent, in a solvent in presence of a hydrolysing amt. of water and adding water to the gelling, homogenised mixt. so that spherical particles are formed in the now 2-phase system. The particles are sepd., dried, tempered and graded.

    Abstract: The invention relates to organosiloxane-amine copolycondensates as random or block copolycondensates or mixtures thereof of units and . R to R is R is directly bonded to the nitrogen atom or the double-bonded radical X and is an alkylene group, cycloalkylene group or or . In this formula, n is 1 to 6 and m is 0 to 6. The free valences of the oxygen atoms bonded to the silicon atom are saturated by silicon atoms of other groups of the formula (III), if appropriate with the incorporation of cross-linkers. X stands for where R" is H or an alkyl group. Preparation processes and the use of the products for the removal of dissolved metals from liquid phase or for the adsorption of gaseous compounds are also given.
