Abstract: The invention relates to a precious metal preparation capable of radiation curing, in particular a gold preparation for the production of decorations on substrates capable of decoration firing, containing a precious metal and a medium capable of radiation curing. The printing medium according to the invention contains one or more organic compounds in particle form, which are insoluble and incapable of swelling in the printing medium and burn away substantially completely in decoration firing, as means of increasing the pigment volume concentration (PVC), whereby decoration quality is improved. Preferred means of increasing the PVC are organic pigments and organic polymers, used in particular in combination. Transfers according to the invention contain the precious metal preparation in radiation-cured form.

Abstract: A device for protecting the wheels of a vehicle against hydroplaning, having a water film displacement device (4,9) the displacement cross section of which is smaller than its operational cross-section. A deflecting device (11) may be arranged behind the displacement device (4,9) to deflect the hurled up water from the area of the wheel to be protected.

Abstract: A tire unit consisting of a coreless air tire (4), containing a reinforcing ply (7), and a rim (3), the edges (8, 10) of which are permanently connected to one another solely by bonding. The part of the tire edge (8) containing the reinforcing ply is bonded to the latter only on one side of the rim. The rim edge (10) has an undercut (28) in which the tire edge (8) contains an annular reinforcement (29). A main bonding zone (23, 37) is provided in the undercut or adjacent to it on the outside. In the main bonding zone, the tangential angle (25) to the axis (1) is at no point (24) smaller than at each point which lies closer to the tire side wall (6) or smaller than the angle (20) at which the tire side wall (6) runs clear of the rim under all normal loading conditions. Moreover, a process is proposed for producing such a tire unit.
