Abstract: In order to simplify mounting of the inner ring (5) of one of the bearings (102) of a wheel hub on the associated spindle (1) and in order to perform keying together of this ring and the spindle by means of multiple-lobe—for example three-lobe-machining which can be performed using the same machine for turning the spindle and the ring, this same three-lobe machining operation is such as to involve all or only partly the shoulder (6) of the spindle and involve, in recessed form, the corresponding inner end of the ring (5) intended to rest against this shoulder, so that the said ring (5) may be mounted on the spindle (1) as though these two parts were two normal parts with a round cross-section and therefore without any need for prior relative angular alignment thereof.

Abstract: The small size cellular telephone (T) is fixed on a telescopic slide (201, 101) sliding on a guide (1) which can be longitudinally secured on the user's arm (B), at the wrist (P). When the cellular telephone calls and has the vibration signaller warning system activated, the vibrations are easily transmitted to the slides and guide system and from this last to the user's wrist who can this way instantaneously notice the call state, even if he is in a noisy place. By catching the cellular telephone with the free hand, the user can extend the guides and quickly bring the cellular telephone itself to the palm of the hand to use it. When the conversation is over, the cellular telephone can be as well quickly taken back to the backward rest position on the wrist. Suitable release means are provided to keep the slides in the backward rest position and if required also in the extended use position of the cellular telephone.

Abstract: The annular workpiece (P) to be machined is positioned by one of its bases and with axial alignment onto a cylindrical base structure (1) onto which the workpiece remains secured due to the presence of a suitable adhesive (2) which for example has been previously distributed onto the said base structure. After the setting of the adhesive, the workpiece to be machined is loaded onto the machine tool, so as to be clamped by the chuck of this latter through the base structure (1) which carries it, and no more directly as in the known art. The clamping forces of the chuck are thus discharged onto the base structure (1) and they do not deform at all the workpiece (P) which can be machined with high precision and quickly, both on its inner and outer surfaces and, if required, also on its free base.
