Abstract: In a method, a short-circuit ring for a squirrel cage of an electric machine is produced through an automated additive production method in one piece with a recess for receiving one end of a cage bar. Material is introduced into a well with a well contour adjacent to the recess on a front axial end of the short-circuit ring through the additive production method, and introduction of the material is repeated into further such wells until all the wells to be filled have been provided with the material, so that the short-circuit ring is connected to the cage bars in an electrically conductive and mechanically robust manner.

Abstract: The invention relates to a suspension comprising a water-miscible, preferably aqueous, solvent, graphene flakes and at least one additive of the formula I cR(-Sp-W)x??(I), having the structural elements cR, Sp and W. The invention further relates to a process for producing the suspension, graphene flakes and the use thereof.

Abstract: The invention relates to an improved process for the preparation of thioglycolic acid alkyl esters by heating a reaction mixture which essentially comprises thioglycolic acid, an alcohol and an acid catalyst, the water formed being removed by distillation using a water separator, in which the resulting product mixture is passed over a basic ion exchanger, if appropriate after removal of the acid catalyst.
