    摘要： The reproduction of mono audio signals leads to an unpleasant sound impression because of the lack of any spatial character. It is therefore desirable to produce a two-channel signal electrically from the single-channel input signal. Some of the known single-band methods are very costly and provide only an inadequate impression of a spatial character. In the case of the invention, a plurality of signals of different types are first of all formed from the mono input signal by filtering, and virtual single-band stereo signals are then generated separately for each of these signals of different types. These stereo signals are subsequently combined to form two output signals.

    摘要： A cylindrical hub for winding web-like or tape-like magnetic recording media of relatively great length. With a winding tension of not more than 2N/cm width of the wound magnetic recording medium, the skew measured over the total length of the wound recording medium should be not more than 5 .mu.s. The length of the wound recording medium is at least 5,000 m; the hub may consist, for example, of aluminum, steel or hard pertinax. It was found that the conditions are fulfilled by a hub in which the compression is less than 0.3% of the hub diameter.

    摘要： A process for the production of white and black oxide ceramic surface films on silicon-containing light metal cast alloys by plasma-chemical anodic oxidation. An aluminum cast alloy is pickled with nitric acid and hydrofluoric acid and coated by plasma-chemical anodic oxidation in an aqueous electrolyte. Accordingly, a coating variant is provided particularly for construction parts of silicon-containing light metal cast alloys having complicated shapes which enables the production of uniformly thin oxide ceramic surface films in contrast to conventional coating variants.
