摘要:
The invention relates to acicular, ferromagnetic, ferriferous and cobaltiferrous pigments which contain per 100 mol of the molar sum of iron and cobalt, 5 to 20 mol of cobalt, 1 to 5 mol of aluminium, 3 to 10 mol of silicon, 0.7 to 3.5 mol of phosphorus, and oxygen, the sum of the parts by weight of the elements iron, cobalt, aluminium, silicon, phosphorus and oxygen being 95 to 100 % by weight of the total weight of the pigments. The ferromagnetic pigments can also be used to prepare magnetic recording materials.
摘要:
An anti-copying film or layer is composed of a film or layer of transparent material with a plurality of mutually spaced, at least partially non-transparent areas whose planes are arranged in approximately the same position with respect to the surface of the film or layer, so that from a predetermined viewing angle the surface of the anti-copying film is substantially transparent. These areas are at least partially made of a photosensitive material converted by exposure to radiation into a non-transparent or reflecting material. Grooves or flutes in which the photosensitive material is located may also be provided in the transparent plastic material.

The description relates to package consisting of a two-part cardboard cut-out for pancakes. The base (1) and cover (2) sections have a central circular aperture through which a plastic core sleeve (6) is inserted. The pancakes are placed thereon in stacked array whereafter the cover section is laid on them and the side sections are folded upwards. Shrink-wrap film is drawn over the whole. In this manner the content of the package is protected against damage during transport by both the cardboard and the shrink-wrap film. The package is recyclable or re-usable.
摘要:
A device (5) for receiving and transporting objects, in particular strip- or ribbon-shaped materials wound into spools (30), has a base frame with at least one swivelling stay (8) and axes (9) mounted thereon for receiving the objects. Supporting brackets (10-13) provided on the base frame act as standing and if required protecting means. The receiving axes (9) and supporting brackets (10-13) may be swivelled from a compact rest position into a stable working and transport position. The device (5) is simple and economic to produce in series and may be used both in manufacturing and in overland transport. The device is useful for all sorts of wound strip- or ribbon-shaped objects and for all sorts of perforated disks or the like.
