Abstract: The invention proposes an electric motor having a rotor, a rotor and a process for manufacturing a rotor for an electric motor, in which the manufacturing complexity is considerably reduced in comparison with the prior art. This object is achieved by virtue of the fact that, in the rotor, a plastics connection (11, 12) is provided between the return plate (2) and the rotor shaft (1). This plastics connection (11, 12) between the return plate (2) and the rotor shaft (1) is produced in accordance with the manufacturing process according to the invention by injection-molding.

Abstract: Method of preparing homogeneous mixtures of liquid and/or solid perfume materials by mixing the components and liquefying the mixture, in which a binary or ternary eutectic premix which is liquid at room temperature and contains 10-90% of the individual substances in the case of binary mixtures and 10-70% in the case of ternary mixtures is formed froma) the solid 6-acetyl-1,1,3,4,4,6-hexamethyltetrahydronaphthalene,b) the solid or oily .alpha.,n-hexylcinnamaldehyde,c) the oily p-tert-butyl-.alpha.-methylhydrocinnamaldehyde,d) the solid p-methoxyacetophenone ande) the solid benzyl o-hydroxybenzoate,and the remaining solid and liquid products are introduced into this mixture simultaneously or in a sequence which is freely chosen for the particular mixture and is independent of the chemical and physical nature of the substances, and the binary and ternary eutectic premixes prepared in this manner.
