Abstract: The finely divided high-structure precipitated silica, which has a
 BET surface area (DIN 60132) of between 150 and 350 m<2>/g
 a compacted bulk density (DIN 53194) of between 60 and 120 g/l
 a DBP number of between 3.0 and 4.0 ml/g
 a particle size distribution of at least 70 % of 1 to 6  mu m. 
<??>It can be prepared by heating a mixture of water and sodium silicate to a temperature of 70 to 80 DEG C with stirring, metering into this mixture concentrated sulphuric acid until half of the alkali present is neutralised, treating the reaction mixture by means of a shearing unit and, if desired, simultaneously increasing the temperature to 86 +/- 5 DEG C, adding concentrated sulphuric acid after a period of 30 to 120 minutes at a higher speed until the pH of the silica suspension formed is 3.0 to 3.5, diluting, if desired, the silica suspension with water, separating off, if desired, the coarse portion by means of a centrifugal pump and a hydrocyclone, filtering off the silica using a known filtering device, washing the silica filter cake free of sulphate, redispersing the silica filter cake with the addition of water and using a stirrer to give a suspension having a solids content of 80 +/- 10 g/l, adding to this suspension, if desired, alkyldimethylbenzylammonium chloride, spray drying the suspension thus obtained and, if desired, milling the dried product. 
<??>The precipitated silica can be used as matting agents in paints either in uncoated or coated form.

Abstract: Using the adjusting device (30), the switching ram (26) of a spring apparatus (19) is adjusted from a locking position into an unlocking position of the spring apparatus (19). In this unlocking position, the chair frame, which consists of a seat support (5), a backrest support (7) and a foot part composed of a support column (1) and a support part (2), can be adjusted in its position. Compared to other designs, the locking and unlocking position is set by a single handle (58) of an operating element (31). This causes the adjusting device (30) to be simpler and more easy to operate.

Abstract: The invention relates to a process and an apparatus for anodic or cathodic painting of hollow bodies, particularly cans such as drink cans or the like, using a water-soluble paint as electrolyte liquid. The latter is in contact with the cathode or anode and is fed in at least one uninterrupted jet, which produces a conducting connection, to the surfaces of the hollow body which form the anode or cathode. 
<??>In order to be able to coat hollow bodies in large numbers per unit time with such a process, the invention proposes that the hollow bodies (1) are pushed with the opening (3) down over an electrically conducting grid (4), the paint being flooded in or over the hollow bodies in jets rising up through the free spaces between the grid or grating rods from below and the entire inside and outside surface of the hollow bodies being covered with a continuous layer in the process.

Abstract: Process for the improvement of the sulphur yield of an assembly which produces sulphur from from H2S and which consists of a sulphur plant (1), an oxidation and hydrolysis unit (2) and a purification unit (3). Said sulphur plant (1) in producing sulphur provides a residual gas (17b) which incorporates H2O, COS and/or CS2 and H2S and SO2 in a mol ratio of H2S:SO2  >/=  2:1. Said residual gas passes into the unit (2) on a H2S oxidation and COS and CS2 hydrolysis catalyst which functions between 180  DEG C and 700  DEG C, in the presence of air (47), thus producing a residual gas (38) free of COS and CS2 and incorporating H2S and SO2 in a mol ratio which is kept equal to 2:1 by regulating the air flow (47). The residual gas (38) is introduced into the purification unit (3), in which H2S and SO2 are made to react in order to produce sulphur and to obtain a purified residual gas (45).

Abstract: A method of mutagenesis by which a predetermined amino acid is introduced into each and every position of a selected set of positions in a preselected region (or several different regions) of a protein to produce library of mutants. The method is based on the premise that certain amino acids play crucial role in the structure and fuction of proteins. Libraries can be generated which contain a high proportion of the desired mutants and are of reasonable size for screening. This libraries can be used to study the role of specific amino acids in protein structure and function and to develop new or improved proteins and polypeptides such as enzymes, antibodies, single chain antibodies and catalytic antibodies.
