摘要： The present invention relates to a method for providing at least one insertion label on a tool of a machine, the insertion label being insertable into a mold half of a tool of a plastics processing machine, in particular injection molding machine or deep-drawing machine. In this method insertion labels are punched out of label web material by means of a punching device consisting essentially of a punching plate and a cutting tool. The insertion labels are transferred by a carrier, which belongs to the punching device, to the tool of the machine and are discharged for insertion thereinto. So far a great problem has consisted in performing such a transfer in such a manner that the insertion label is positioned in a sufficiently precise manner without creases. This problem is overcome in that after the punching operation the insertion labels are held by the punching plate which is movable substantially in a direction transverse to the punching direction and formed as a carrier, and are transferred to the tool of the machine. Furthermore, the present invention relates to an apparatus for performing the method.

摘要： Salts of riboflavin 5'-phosphate which are obtained by phosphorylation of riboflavin and reaction of the resulting riboflavin 5'-phosphate (5'-FMN), contaminated with unconverted riboflavin and isomeric riboflavin monophosphates and diphosphates, with an alkali metal hydroxide or a nitrogen base are purified by a process in which(a) a roughly 1-15% strength by weight homogeneous, clear, aqueous 5'-FMN salt solution having a pH of from 4 to 7 is prepared from the crude 5'-FMN obtained in the phosphorylation, water and the alkali metal hydroxide or the nitrogen base, preferably sodium hydroxide solution, if necessary with heating at from 30.degree. to 100.degree. C.,(b) the resulting solution is treated with a suitable polymeric adsorber resin and(c) the 5'-FMN salt substantially freed from unconverted riboflavin is isolated from the resulting solution and, if desired, the solution is fed to a subsequent fine purification.Treatment with the suitable polymeric adsorber resin is advantageously carried out in a column filled with adsorber resin. The subsequent fine purification can be effected by evaporative crystallization or by chromatographing a 5'-FMN solution, containing from 1 to 15% by weight of dry substance, in water or in a mixture of water and a lower aliphatic alcohol, having a pH of from 4 to 7, in a minimum amount of from 5 to 50% of the bed volume of the column over RP silica gel derivatized with alkyl groups, using water, or a mixture of water and a lower aliphatic alcohol, as the eluant. Preparative chromatography of 5'-FMN salts over derivatized RP silica gel using water, or a mixture of water and a lower aliphatic alcohol, as the solvent and eluant is also claimed independently of pretreatment with the suitable adsorber resin.
