Abstract: Phosphoric acid is separated from aqueous solutions of thiamine phosphates which are obtained in the phosphorylation of thiamine, with or without subsequent partial hydrolysis, by a process in which the phosphoric acid is converted with a virtually water-insoluble or only slightly water-soluble tertiary amine into the corresponding salt and the latter is extracted with a virtually water-immiscible or only slightly water-miscible solvent of moderate polarity. In a particularly advantageous procedure, the phosphoric acid is extracted with a mixture of a virtually water-insoluble or only slightly water-soluble tertiary amine and a virtually water-immiscible or only slightly water-miscible solvent of moderate polarity.

Abstract: A pressure spring for tape cassettes which consists of a spring steel strip which is, in particular, narrow and is of roughly uniform width comprises a flat central part and curved spring arms adjacent to said part and having a continuous curve. The flat central part has, as fastening parts, holes with indented fastening collars which, together with rivet pegs and recesses in a housing wall, form a roughly projection-free spring fastening, the riveted peg ending roughly at the spring surface. The pressure spring exhibits a straight line with a defined slope in the operating region of its spring characteristic. The pressure spring can be used for tape cassettes of all types, in particular for video cassettes.
