Title: Sulphur recovery from Claus off-gases - by reducing sulphur dioxide to hydrogen sulphide and oxidising
IPC: C01B17/04
Filed: 1973-07-03
Abstract: Sulphur is prepd. from Claus off-gases by (a) raising the temp. of the off-gases >175 degrees C, (b) reducing the sulphur dioxide to hydrogen sulphide by passing over a sulphided Gp. VI-VIII catalyst on an inorg. oxide support in the presence of a hydrogen-contg. gas,(c) cooling the formed mixt. (d) removing at least a part of the water, (e) passing the formed gaseous mixt. through a basic aq. soln. to absorb at least a part of the hydrogen sulphide, and (f) converting the absorbed hydrogen sulphide in this soln. to elementary sulphur by oxidn. in the presence of a catalyst. The temp. increase in stage (a) is produced by passing the Claus off-gases through a direct burner in which a fuel is burned with an O2-contg. gas, the H2-contg. gas for stage (b) being directly introduced into this burner. Gives efficient sulphur recovery without risk of explosions.

Title: Abrasive tools, esp. rotatable grinders - having diamond or boron nitride crystals embedded in metal layer bonded to support, and covered with resin
IPC: B24D5/00
Filed: 1976-09-13
Abstract: Abrasive tool has a supporting body, e.g. a steel cylinder, and a large number of diamond or cubic boron nitride crystals, partly embedded in a metal layer bonded to the supporting body.

Abstract: Atorvastatin, a substance with the chemical name hemi calcium salt of (R-(R*,R*))-2-(4-fluorophenyl)-beta, delta-dihydroxy-5-(1 methylethyl)-3-phenyl-4((enylamino)carbonyl)-1H-pyrrol-1-heptanoic acid is known as the inhibitor of HMG-CoA reductase and has been used as an antihypercholesterolemic. Atorvastatin has been always prepared in the form of a calcium salt convenient for preparation of suitable pharmaceutical formulations such as pills, capsules, powders and other forms appropriate for oral administration. It can exist in the amorphous as well as one of the four crystalline forms (Form I, II, III, and IV). Atorvastatin is a very low water-soluble substance, but its crystalline forms are even lower soluble than the amorphous one, a fact that may influence its biological availability in body. The submitted invention refers to a new procedure of transformation of the crystalline atorvastatin into the amorphous one.
