Abstract: Valve for thermal-regenerative waste gas purification installation; may be installed in connecting duct of the installation, the duct connecting gas inlet duct or gas outlet duct for inlet or outlet of untreated or treated waste gas with treatment chamber, having conical valve seat and an obturator of corresponding shape, operative to close an orifice formed by the valve seat, wherein the obturator is connected with a stem for actuation of the obturator. The obturator may comprise upper obturator plate and lower obturator plate, mounted spaced apart from one another, the stem comprising an axial internal bore, which is connected with a space between the obturator plates, in order to connect the space directly with the outside environment or with an external fan or air compressor.

Abstract: Compounds of the formula ##STR1## wherein n.sup.1 -n.sup.9 are each independently 0 or 1;m.sup.1 -m.sup.9 are each independently 0 or 1, but with the proviso that at least one of m.sup.1, m.sup.2 and m.sup.3, at least one of m.sup.4, m.sup.5 and m.sup.6 and, when present, at least one of m.sup.7, m.sup.8 and m.sup.9 is 1; and whereinX.sup.1 -X.sup.18 each independently is --O--, --CONR.sup.1,--NR.sup.1 CO-- or --NR.sup.1 --;R.sup.1 is hydrogen or lower alkyl;W is a benzene or s-triazine;Y.sup.1 -Y.sup.9 each independently is an aromatic ring systems;A.sup.1 -A.sup.3 each independently is a residue of a sugar alcohol devoid of the 1-hydroxy group or a derivative thereof, a residue of a sugar acid devoid of the 1-carboxy group or a derivative thereof or tris-(hydroxymethyl)-methyl;D is the di-residue of a sugar alcohol devoid of 2 hydroxy groups or a derivative thereof or the di-residue of a sugar dicarboxylic acid devoid of 2 carboxy group or a derivative thereof;Q.sup.1 -Q.sup.3 and Z.sup.

Abstract: Compounds of formulas ##STR1## wherein, B is lower alkylene or an optionally substituted aromatic ring system;G.sup.1, G.sup.2 and G.sup.3 each independently signify a residue of a glycopyranoside, a glycopyranose or a derivative thereof, with at least one hydroxy group of residue G.sup.1, G.sup.2 or G.sup.3 being esterified with sulfuric acid, and pharmaceutically usable salts thereof, are useful for the treatment of disorders which are characterized by excessive or destructive proliferation of smooth muscle cells.

Abstract: The present invention is concerned with novel sulfuric acid esters of sugar alcohols and sugar alcohol-like compounds of the formula ##STR1## Also described are methods for the treatment and/or prophylaxis of arteriosclerotic changes in the vascular wall as well as a process for the manufacture of the compounds of formula I and their salts.
