Processes and apparatuses for partly disassembling tape cassettes having at least one closure flap comprise separating the closure flap from the cassette or from the cassette housing at an early time, before, during or shortly after the opening of the cassette. Several process methods and examples of apparatus are specified. The separating methods and apparatuses can be expediently used for all tape cassettes with one or more closure flaps, it being possible for these to be any type of audio, video and data cassettes.

Continuous recovery of raw materials from coated films and apparatus for this purpose and film material recovered therewith. Large amounts of coated films can be fed to a continuous recycling process in which any pigments present in the coating and the substrate material are recovered. The treatment is carried out at room temperature in an alkaline medium consisting of soft soap, organic solvent and/or water, with or without the use of a catalyst. The solvent is recycled. After the first treatment stage, the film shreds can be treated in a second stage with a solvent/water mixture similarly to the first stage, and thorough final washing in a water or solvent circulation is effected in a third stage. The recovered film shreds are dried, pressed, milled and brought to the desired shape in a plastics agglomerator, and the recovered pigments are dried under reduced pressure (FIG.,). The process and apparatus can be used with advantage for any type of substrate or printed media, for example for magnetic substrates, photographic substrates, printing plates, pigment-free substrates.

A protective container is provided for substantially cuboidal objects which is in the form of a hollow cuboid case which is open on one side. A case part is provided for covering the open side, the case part is U-shaped or partially U-shaped in this position. A closure arrangement is provided which connects the hollow cuboid case and the case part reveals when the container is opened for the first time. This container is especially well-suited for use with cassettes of all types, as well as other substantially cuboidal articles.

Stabilized acicular ferromagnetic chromium dioxide is prepared by a method in which the chromium dioxide surface formed as a result of a reductive treatment is treated with adsorbed monobasic or polybasic hydroxycarboxylic acids.
