Abstract: The present invention relates to a device for demonstrating the antistatic properties of at least one first transparent glass substrate, at least part of one of the main surfaces of which is an antistatic surface, said device comprising a hollow box having an upper surface provided with at least one window to which said first transparent glass substrate is fitted, wherein said box contains elements capable of moving under the action of electrostatic attraction, said elements being chosen from cellular particles of synthetic or natural polymers, individualized fibers of synthetic or natural polymers and their blends. The present invention further relates to a method for demonstrating the antistatic properties of at least one first transparent glass substrate by means of the above device.

Abstract: The invention concerns a method which consists in a process known per se in producing, on the curved substrate (10) to be treated, a film of material derived from a specific material source (13). The invention is characterized in that it consists in inserting, between the curved substrate (10) and the material source (13), a mask (19) relative to the curved substrate (10), preferably selecting as mask (19), a mask comprising a ring-shaped part (20). The invention is particularly useful for providing lenses with antiglare treatment.

Abstract: This device for fixing a steering column to the bodywork of a motor vehicle, in which the column (1) is connected to an assembly member (2), and this member to the bodywork (3) of the vehicle via fixing means, is characterized in that the fixing means comprise means (4) for hooking the member to the bodywork and means (5, 6) suitable for producing a mechanical stress between this member and the bodywork in order to ensure that the member is fixed under stress to the bodywork. This device advantageously comprises, in proximity to one of the ends of the member (2), the hooking means (4), in proximity to the other end of this member, means (5) for clamping the member to the bodywork, and, between these hooking and clamping means, means (6) tending to distance this member from the bodywork.

Abstract: A telescopic steering-wheel shaft (1) is rotatably mounted in a column body (4-6) capable of pivoting about a horizontal axis (17). The column body (6) is supported at one end by a slide (48) for suspension on a rack (26) driven by a pinion (24) carried by the output shaft of a geared motor (20). A pressure screw (52) acting on the column body and on the slide ensures that play is taken up. The column body (6) is connected at its opposite end to a rack driven by a pinion (80) carried by the output shaft of a second geared motor (84).

Abstract: This connection has, on one of two shafts, a hollow socket (1) which is connected to a driving block (16) whose inner surface forms a frustum of a pyramid for receiving a pyramidal head (24) connected to the second shaft. Furthermore, the socket (1) carries retractable pins (6) urged toward the interior by an elastic system (12, 8) but retained in an outer position by an inner ring (14) which is displaced by the elongated stem of the second shaft when it is fitted in the socket. Notches (30) for receiving the pins (6) are provided on the stem (22) and contribute to the axial locking of the two shafts.

Abstract: The tubular part (1) passes through a middle support piece (25) which is arranged between two clamping flanges (17a, 17b). A tie rod (21) passes through the flanges (17) and bears against the external surfaces of these flanges by means of a stop (29) and a clamping device on the one hand, and a nut (31), on the other hand. The clamping device consists of a bistable toggle-joint system comprising two levers (40,41) located in between the stop (29) and a bearing part (34). The stop (29), the levers (40,41) and the bearing part (34) have complementary hinging surfaces which are freely engaged with each other for assembly of the clamping device. With the device according to the invention it is possible to fix a steering column which can be continuously adjusted by pivoting and/or sliding. It is also possible to absorb the torques which may be transmitted to the steering column when the anti-theft device of the vehicle is engaged.

Abstract: This shaft is formed by a tube in a single piece having one end portion which is enlarged and cut away so as to constitute a universal joint yoke 5. A main cylindrical body 18 having a wall of reduced thickness connects this yoke to a portion 23 of greater wall thickness and provided with two slots 22 constituting a locking keeper. At the end of the shaft opposed to the yoke there is formed a steering wheel support constituted by a portion of the tube which has a smaller diameter and a greater wall thickness.
