Abstract:
Buffer container intended to a coin collector station or the like for a toll installation, comprising a storage box (6), a lock chamber (7), first and second closing devices (10, 13) for the box and the lock chamber being either in a closed or open position.
Abstract:
A device for checking metal items, especially coins, which comprises a sorting mechanism essentially consisting of a single motor-driven circular tray (4) by means of which the operations of separating and recognising the coins can be performed simultaneously, said tray being toothed around its periphery and reinforced at the centre by a component (9) of truncated conical shape on which the loose coins fall into an inlet area, said tray rotating above a fixed component (2) almost entirely surrounded by a circular rim (3) on to which the coins slide when engaged between the teeth of the tray and also of means for recognising and certifying the coins, taking account of their material, thickness and diameter, comprising a single electromagnetic detector (15) located above tray (4).
Abstract:
A fiber preform for a hollow turbine engine vane, the preform comprising a main fiber structure obtained by three-dimensional weaving and including at least one main part (41), wherein the main part (41) extends from a first link strip (44p), includes a first main longitudinal portion (46) suitable for forming essentially a pressure side wall of an airfoil, then includes an U-turn bend portion (45) suitable for forming essentially a leading edge or a trailing edge of the airfoil, then includes a second main longitudinal portion (47) facing the first main longitudinal portion (46) and suitable for forming essentially a suction side wall of the airfoil, and terminating at a second link strip (44q), wherein the first and second link strips (44p, 44q) are secured to each other and form a link portion (44) of the main fiber structure, and wherein the main longitudinal portions (46, 47) are spaced apart so as to form a gap between said main longitudinal portions (46, 47) suitable for forming a hollow in the airfoil.
Abstract:
Aube (1) de turbine de turbomachine en composite à matrice céramique et procédé de fabrication d'une talle aube. Le pied (3) de l'aube (1) comprend une préforme (30) fibreuse unique densifiée comportant au moins un évidement (40, 50) réalisé par usinage, chaque point du pied (3) de l'aube étant situé à une distance d'une surface libre du pied (3) au plus égale à deux fois la distance maximale (Δ) de pénétration dans la préforme (30) des gaz de densification de cette préforme (30), et la partie distale du pied (30) de l'aube comportant une paroi distale (35) continue d'un seul tenant.
