Title: Variable-focus objective allowing very close-up focusing
Inventor: CORBASSON GERARD
IPC: G02B7/10
Filed: 1988-02-02
Abstract: This method and this device relate to variable-focus objectives comprising a category of two sets II and III of lenses providing the variation in the focal length as they are moved axially, and another category of at least one set I or V of lenses whose movement along the axis causes a variation in the object focusing distance. In order to focus on an object very close to the objective, not only is the group or groups I, V of lenses of the category providing the focusing moved, but the groups II and III of lenses of the category normally providing the sole variation in the focal length are simultaneously moved, so as to compensate for a parasitic variation in the apparent field which, without it, would occur in such a case. For this purpose, the two systems for controlling the device are slaved to each other, so that, for focusing on an object very close to the objective, the focusing-control system acts on the system for controlling the sets II and III of lenses of the first category so as to move them simultaneously.
Patent FR-2626653-A1 (FR)
Title: Light diffuser whose colour and light intensity vary randomly
Inventor: FONTE PATRICE
IPC: F21S10/02
Filed: 1988-02-02
Abstract: The principle of the light diffuser is based on the synthesis of colours by addition. The light sources are coloured incandescent lamps supplied with a sinusoidal alternating voltage whose phase angle will be varied. Addition is carried out by an opaline surface containing the light sources and diffusing the resulting colour. The luminosity of each of the sources is varied continuously but non-linearly, that is to say that the phase angle of the voltage supplied to each source varies progressively, but without following a predetermined progression curve. The progression curve of each source is governed by a random system comparing at an instant two independent physical magnitudes. The present system can in particular be used as a background light which diffuses into an area, a light whose intensity and colour cannot be anticipated.

Abstract: PCT No. PCT/FR89/00373 Sec. 371 Date Jan. 22, 1991 Sec. 102(e) Date Jan. 22, 1991 PCT Filed Jul. 12, 1989 PCT Pub. No. WO90/01121 PCT Pub. Date Feb. 8, 1990.The invention relates to a fastener member for the production of assemblies, in particular a rivet. This fastener means includes a shank (1) and a head (2) intended to be deformed by flattening during installation. On its front face, this head has an annular groove (5) extending around the axis and positioned in proximity to the alignment of the exterior surface of the shank. This groove defines on the head two portions, one central (2C), the other peripheral (2P), able to be deformed independently under the effect of flattening. The invention enables a considerable improvement of the distribution of compressive forces between the fastener means and the materials to be assembled. It assures a satisfactory radial expansion of the head, as well as a sufficient flow of material toward the shank and the junction zone between shank and head.

IPC: B64G1/00
Filed: 1989-01-26
Abstract: L'invention concerne un système de commande de vecteur de poussée pour diriger et commander un véhicule aérospatial propulsé par un moteur du type à réaction. Le système de commande de vecteur de poussée perfectionné fait simultanément tourner et effectuer un mouvement de translation latéral au moteur à réaction 16 par rapport à l'axe longitudinal 14 du véhicule. Ce mouvement complexe du moteur à réaction engendre des moments de commande suffisamment importants, ce qui permet au moteur à réaction d'être très étroitement rapproché du centre de gravité 12 de véhicule 10. Il en résulte que le véhicule peut être de plus courte longueur et que la structure dont on a typiquement besoin pour positionner le moteur à réaction en un point de pivotement situé plus en arrière est éliminée.

Title: Hydraulic braking circuit provided with a master cylinder and with an anti-lock device for the wheels, for a motor vehicle
Inventor: PICHON JEAN-MARIE
IPC: B60T8/42
Filed: 1989-03-15
Abstract: The circuit comprises a master cylinder 1 which communicates, under normal braking, with lines 7, 7' for supplying the brakes of a wheel 5, 6 through solenoid valves 8, 8'. When locking of the wheels becomes imminent, a pressure generator 12 is started up to make a slide-valve distributor 10, which cuts off the direct communication of the master cylinder 1 with the brakes 5, 6. According to the invention, under normal braking, an abrupt action on the brake pedal does not give rise to an accidental movement of the slide valve 27 of the distributor 10, because the increase in pressure applies to two bearing surfaces of identical cross-section of this slide valve. Application to an anti-lock braking circuit with enhanced operational safety.
