Title: N-Benzylated triazoleazo dyes and preparation thereof
Inventor: NOACK HORST DIPL CHEM
IPC: D06P3/79
Filed: 1993-05-05
Abstract: Known N-benzylated triazoleazo dyes are mixtures which consist of dyes which differ in their degree of benzylation, which is disadvantageous for the purity. Also, the reaction conditions lead to the formation of brown decomposition products which impair the use properties of the dye. The novel N-benzylated triazoleazo dyes are to have a high purity and good dyeing power. The invention provides N-benzylated triazoleazo dyes of the general formula <IMAGE>  where     R1 = hydrogen, methyl or phenyl,   R2 = benzyl, p-methylbenzyl or p-methoxybenzyl, and   An- = chloride, tetrachlorozincate or a p-toluenesulphonate anion,  and a process for their preparation. The novel dyes can be used to produce red to bluish red dyeings. They are used for dyeing polyacrylonitrile fibres, paper and plastic materials.

Title: Process for the production of a rotor and rotor produced by this process
Inventor: EBERLE GUENTER
IPC: B04B5/04
Filed: 1993-05-05
Abstract: The present invention describes a process for the production of a rotor, especially a rotor of a swivelling-bucket centrifuge, and a rotor produced by this process. In order, proceeding from conventional swivelling-bucket rotors with mountings for swivelling buckets, in which the mountings are arranged distributed uniformly in pairs over the circumference and receive the swivelling buckets between them, to develop such a rotor so that it can be produced in a simple and cost-effective way, the solution according to the invention provides for producing a rotor designed as a one-piece bent metal part. For this purpose, first of all, the mountings are cut out from a circular metal disc and these are then bent out of the disc plane in a second step of the process, in order thereby to form the swivel mounting for swivelling buckets to be suspended therein.
