Abstract: A device (1?, 1?, 1??) for manufacturing III-V-crystals and wafers (14) manufactured therefrom, which are free of residual stress and dislocations, from melt (16) of a raw material optionally supplemented by lattice hardening dopants comprises a crucible (2?, 2?, 2??) for receiving the melt (16) having a first section (4?, 4?) including a first cross-sectional area and a second section (6?) for receiving a seed crystal (12) and having a second cross-sectional area, wherein the second cross-sectional area is smaller than the first cross-sectional area and the first and second sections are connected with each other directly or via third section (8, 8?) which tapers from the first section towards the second section, in order to allow a crystallization starting from the seed crystal (12) within the directed temperature field (T) into the solidifying melt.

Abstract: A packaging system for at least one electrical service device is described, which has a transparent packaging configuration. At least one service device is accommodated in the transparent packaging configuration. The transparent packaging configuration has a container. The container has two side walls that accommodate the service device between them. As viewed from the outside, one of the side walls has a depression and the other of the side walls has a protuberance. When a plurality of containers are aligned in a row, one beside another, the protuberance (21) of the first container engages in the depression (20) of the adjacent container, so that the two containers are connected to each other frictionally or with a form locking connection, releasably.

Abstract: A process for producing agglomerates of water-soluble dyes by adding a granulating auxiliary to at least one water-soluble dye, which is in pulverulent form, and converting the mixture, while it is being subjected to a tumbling and/or mixing action, by particle enlargement into a granular form, in which process there is used as a granulating auxiliary:(a) at least one compound of the formula IA--(CH.sub.2 CH.sub.2 O).sub.n --H (I)in which A is the group R--O-- or ##STR1## R is an aliphatic or alicyclic hydrocarbon radical containing 8 to 22 carbon atoms, R' is an aliphatic hydrocarbon radical containing 8 to 22 carbon atoms, and n is 10 to 200, or(b) a mixture of a compound of the formula II ##STR2## in which m is 50 to 500, and x is 3 to 5, with a compound of the formula IIIR.sub.1 --NH--CO--NH--R.sub.1 (III)in which each R.sub.
