L'invention concerne un élément de retenue avant d'une chaussure sur un ski, comprenant une embase prévue pour être reliée de façon solidaire au ski, un corps monté sur l'embase, deux ailes (62, 63) mobiles relativement au corps autour d'axes sensiblement verticaux, et présentant au-delà de leur axe d'articulation un retour d'aile (62a, 63a), un ressort logé dans le corps, un organe de transmis...

The exercise device consists in a bar (1) which is hollow on top and has a spiral borer (3) at each end, to fix it into the ground. The borers pivot on the bar and are stored in the bar when it is not in use. Two handles (4) on top of the borers help to screw them into the ground. The bar folds in the centre (6), for storage, and the two parts are held together by a hook. The bar is long enough to...

A polychromatic light source (20) illuminates a slit (22) through a focussing element (21). The slit (22) is placed at the focus of a collimator (23) to form an image at infinity. A galvanometric mirror (32) sweeps the luminous beam (33) enabling a tomographic section (26) to be selected. A projection objective (25) with known axial chromatism forms a group of monochromatic images (26) of the sli...

A method for making a thin film of optionally crystalline solid material selected from a dielectric material, a conductive material, a semi-insulating material and an unordered semiconductor material. The method comprises an ion implantation step wherein a substrate of the solid material is bombarded with ions selected from rare gas and hydrogen gas ions in order to form a layer of microcavities i...

The image detection method involves segmenting reference images stored in a learning base manually, one at a time during a first phase (1). An operator indicates the number of zones and marks them with a pointer and the exact contours of the zones are then determined using the method of parting waters. The second phase (2) consists of an optimisation of the marking parameters and the calculation o...

The present invention relates to a multi-use receptacle having longitudinally and laterally variable dimensions, comprising a planar bottom and lateral and longitudinal extension devices which cooperate with said bottom by slidingly moving elongate members which are comprised in said extension devices and which are integral with walls forming the walls of the receptacle in an assembly position.; <...

Treatment plant consists of a large annular tank (8), e.g. 10-18 m in diameter and 5-8 m high, containing between 4000 and 18000 m<3> of liquid. The tank has \-2 aeration zones (9) which alternate with anoxia zones (10), with the aeration zones containing perforated aeration tubes (11) and supports (12). The supports are shaped to limit their disturbance to the flow of liquid in the tank, which is...

The access control system uses an electronic key (10) which is provided with a memory (14) which is accessible to the access control system (12). This memory stores an access code which authorises access when the control system has a code corresponding to that of the key. The key memory can also store a code modification authorisation which alters the code used to gain access. The validity of this...

Low rate data D1-D4 and middle rate data D5 and D6 are time division multiplexed independently according to their rates by a time division multiplexer TDM(A) (110) so that their rates are converted into the rate of high rate data D7 and D8 which are not passed through the time division multiplexer TDM(A) (110). Subsequently, the entire data are converted into biorthogonal signals by biorthogonal s...

The metal cup for acetabular implantation, the upper surface (2) of which cup is of a general spherical shape (7) and is equipped with a plurality of orifices (3) for the passage of screws, is characterised by the fact that the upper spherical surface (7) is interrupted before the equatorial plane and is extended by a conical part (6) allowing it to be anchored with force in the acetabular cavity....

The implant cup (5) is hemispherical in shape, with an inner cavity to receive an insert. It is fitted in the acetabulum by impaction and has, to this end, a series of anchoring projections (15) on its outer surface, created by two spiral grooves (38) with opposite pitches. The grooves intersect one another over a large proportion of the cup's outer face and are inclined towards its open end. They...
