Machine for making road markings (signals) and method of production of such road markings

The invention relates to a machine for making road markings, and especially, but not exclusively, laying closure arrows, and to the method of producing such markings. It is characterised in that the spray gun support is guided in rotation, but locked in translation, with respect to a substantially vertical axis 18 and is provided with a means 19 for controlling this rotation as well as, preferably, an indexing means 20.

Cotyloidal implant fixed without cement

Cet implant cotyloïdien comprend une cupule (5) de forme hémisphérique, délimitant une cavité intérieure (10), et un insert (7) pouvant être engagé dans cette cavité, la cupule étant mise en place par impaction et comprenant, à cet effet, des aspérités d'ancrage (15) aménagées sur sa face extérieure, qui présentent une forme de losange e t qui sont contiguës et imbriquées; la cupule (5) comprend, aménagées dans sa face extérieure coaxialement à elle, deux rainures en form e de filets hélicoïdaux (38) de pas inverses, qui s'entrecroisent l'une l'autre sur une large partie de cette face externe, qui sont inclinées en direction de l'ouverture de la cupule et qui présentent une profondeur augmentant progressivement en direction de l'ouverture de la cupu le (5), ces rainures par leur entrecroisement, délimitant un nombre important d'aspérités (15). L'invention permet de réaliser un implant cotyloïdien pouvant être ancré au bassin sans ciment et sans recourir à la mise en place de vis.
