Abstract: The invention concerns a volatile substance diffuser (102) comprising a body (104) with an aperture (111), and a reservoir (120) of product, comprising a volatile substance, the reservoir (102) being mounted mobile in the body (104) between a diffusing position enabling a gas to circulate through the product, then through the aperture (111) and a closed position wherein the product is isolated from the aperture (111), the reservoir and the body having respective surfaces (122,116) extending opposite each other. One of the surfaces (122) is spherical.

Abstract: Inflatable packaging cushion (100).According to the invention, the inflatable cushion includes:an external peripheral edge (101) adapted to the shape and to the dimension of a packing receptacle,at least one internal opening (102, 102') capable of receiving at least one object to be packaged,a plurality of recesses (103, 103') extending from each internal opening towards the peripheral edge, the recesses delimiting in pairs wedging parts (104, 105, 106, 107, 104', 105', 106', 107') capable of coming into contact with the object, zones for preferential pivoting (108) of the wedging parts being defined between the recesses and the peripheral edge, the wedging parts being able to pivot during the inflating about the preferential pivoting zones in order to vary the size and/or the shape of each internal opening and to adapt it to objects of different sizes, whilst exerting a holding pressure on the object or objects.Application to the packaging of objects of different sizes and/or shapes.

Abstract: A consumable article for diffusing active volatile substances, in particular perfume, into the ambient atmosphere, the article comprising a support element of shrinkable material, in particular heat shrink material, with the volatile substance being absorbed in the support element. The invention also provides a method of diffusing volatile substances, in particular perfume, by means of an article of this type, and also a device for implementing the method.

Abstract: The invention relates to a method of preparation of an outer cover of a fusion roller for a xerographic machine, this cover being constituted by a homogeneous layer covering a hollow metal core receiving heating means.According to the invention, this method comprises the steps of (a) cold kneading a mixture having, for 100 parts of fluorine-containing rubber, 55 to 60 parts of carbon black, 2 to 6 parts of magnesium oxide, 4 to 8 parts of calcium hydroxyde and 0 to 2 parts of polyethylene wax; (b) forming the covering material by extrusion or calendering of this mixture; (c) application of this material in a homogeneous layer to the surface of the metallic core of the roller; (d) vulvanization at elevated temperature and under pressure of the material thus applied to the core; (e) dressing of the cover to a constant thickness.
