Abstract: An airbag covering cap including a support layer and a covering layer of different elasticities, having at least one tear-off line along which the airbag covering cap tears open when the airbag is deployed. The covering layer is weakened by a groove in the region of the tear-off line and the support layer extends into this groove. The covering layer has a section adjacent to the section of the support layer, which extends into said support layer. The edge between the sections of the support and covering layers, each extending into the other layer is configured as a tear-off edge.

Abstract: The invention relates to an airbag covering cap comprising a support layer and a covering layer of different elasticities, having at least one tear-off line along which the airbag covering cap tears open when the airbag is deployed. The covering layer is weakened by a groove in the region of the tear-off line and the support layer extends into this groove. In accordance with the invention, the covering layer (13) has a section (13a), adjacent to the section (11a) of the support layer (11), which extends into said support layer (11). The edge between the sections (11a, 13a) of the support and covering layers (11, 13), each extending into the other layer, is configured as a tear-off edge (14, 15).

Abstract: Chemical decontamination of large components and systems of metallic materials of nuclear reactors with a liquid reactor coolant, wherein the treatment is carried out by means of an aqueous solution of oxidizing chemicals which is moved through the large components and systems to be decontaminated. Nitrates, chromates or Ce-IV salts are added as oxidizing chemicals in the particularly borate-containing primary coolant and also an addition of ozone is used.
