Abstract: A device for masking automobile vehicle headlights comprises at least one transparent optical element (B) inserted on the path of light rays between lighting sources and the headlight glass, the optical element (B) comprising a cylindrical entry face (E3) with radius R and a cylindrical exit face (E4) with radius R symmetrical to the entry face (E3) about a vertical median plane located at a distance 2R from the entry face (E3) and the exit face (E4), a mask (C) being placed in the vertical median plane and offset from the horizontal plane of symmetry.

Abstract: A generator for charging the battery of a portable instrument such as a portable telephone, a player or the like, includes a permanent magnet in the form of a bar mounted freely in rotation about a pivotal axle corresponding to its median axis, within a magnetic circuit which is the core of a winding, the permanent magnet carrying a weight adjacent one of its ends, this assembly being mounted in the instrument such that, during movement of the portable instrument, the magnet unbalanced by the weight, pivots about its axle and relative to the magnetic circuit, which induces, in the winding, a current used to charge the battery of the instrument.

Abstract: An installation for supplying electrical power to all the electrical consumers in a given area, the electrical consumers being without power lines and positioned in any spot whatsoever within the area. The installation comprises elements for inducing a magnetic field in the area and a number of units (1) associated with the electrical consumers for receiving the magnetic field and producing electrical power. The elements for creating a magnetic field include at least N turns of an electrical conductor situated on the circumference of the surface area, traversed by an alternating current, with at least one capacitor being placed in series in the turns. Application to electrical installations in premises and offices.

Abstract: The invention relates to a masked beam motor vehicle headlamp of the type comprising, in succession: a reflector (1); a light source (3); a masking screen (E) having a cutoff edge (A); and a converging lens (4). The headlamp is characterized in that the screen is fitted, beneath its cutoff edge (A) and at least in its central portion, with an opening suitable for allowing a portion of the light flux directed towards the screen to pass therethrough. Means are provided to direct said light flux passing through said opening so that it is combined with the light flux which is not intercepted by the screen, thereby improving the light characteristics of the masked beam as finally projected by the headlamp.

Abstract: The corrector device comprises at least one illumination sensor (10, a, b, c) integrated in a headlamp and fixed to move with the headlamp reflector (12), the sensor-reflector assembly normally pointing in such a direction as to detect the luminance of the road in at least one angular direction at a predetermined angle (o+.phi.+.theta.) with the horizontal (OY), with processing means being provided that are suitable for generating a corrector signal which is a function of the luminance of the road in said direction, whenever the trim of the vehicle changes, the device further including at least one actuator controlled by said corrector signal in order correct the direction in which the reflector-sensor assembly is pointing.

Abstract: The invention relates to a rotary electric machine able to be used as a speed variator and/or a torque converter. It comprises a stator with s pairs of poles, a central rotor (RM) with p pairs of poles and an intermediate rotor (RT) comprising, at its inner face, at least one primary electric circuit subjected to the field of the central rotor (RM) and, at its outer face, at least one secondary electric circuit subjected to the stator field. A switching circuit controls the passage, through the secondary circuit, of the current produced in the primary circuit, in a direction such that the torque exerted by the stator (F) on the rotor (RT) is in the same direction.

Abstract: A headlamp comprising a reflector of which at least one sector is in the form of a paraboloid of reduction, a bulb with an axial filament offset upwards in the radial direction with respect to the axis of the paraboloid, and a light-distributing glass placed in front of the reflector. The filament is centered in the axial direction on the focus of the paraboloid. The surfaces of the reflector situated outside the sector in the form of a paraboloid are designed so as to produce images of the filament which are all situated below the cut-off. Alternatively, the light-distributing glass participates in the deflection, in combination with the surfaces of the reflector. In an advantageous variant the reflector is completely parabolic and homologous deflecting zones are then provided on the light-distributing glass to lower all the images thus produced below the cut-off.

Abstract: A light transmitting system for an automobile headlamp having a real light source, means for a light channel and an elliptical reflector for concentrating the radiation from this source on the end of the light channel provided with a plurality of reflecting facets. The light channel is formed by a single transparent bar arranged horizontally and transversely with reference to the direction of illumination. The front of the bar is formed as a vertical light output face and the rear of the bar has a series of vertical steps defining a series of oblique vertical reflecting facets thus constituting as many virtual light sources. These facets are arranged in optical co-operation with lenses having axes parallel to the direction of illumination so that these lenses project images corresponding to the facets in the direction of illumination in order to form an assembly of elementary light beams merging into one single beam.

Abstract: This invention relates to a headlamp inter alia for motor vehicles.The headlamp comprises a lens (1) formed by a number of juxtaposed dioptric elements (4) each having a focal point (F) and an axis (5); a light source (6-10) is provided for each element (4) vary near the focal point thereof; the axes (5) of the various dioptric elements (4) are so arranged that the elementary light beams issuing from the elements (4) when the corresponding sources (6-10) are illuminated form a single beam having a predetermined light distribution.Of use for the construction of very shallow headlamps suitable for integration in the bodywork.
