Patent FR-2625572-A1 (FR)
Title: Cranked bifocal optical system with oriented field
Inventor: PERRIN JEAN-CLAUDE
IPC: G02B13/14
Filed: 1987-12-30
Abstract: This cranked infrared bifocal optical system fulfils the functions of focus changing (long focal length, short focal length), of temperature focusing and of finite-distance focusing. It consists of three lenses L1, L2, L3 and of a mirror M in order to crank the beam. The lens L2 is tilted about the mirror M in order to switch over the system from long or short focal lengths, whereas the lens L3 is moved translationally for temperature-focusing or finite-distance focusing corrections. The beam can be oriented by means of the mirror M and, additionally, by means of the lens L2.
Patent WO-8905403-A1 (WO)
Inventor: GUAL DOMINIQUE
IPC: F03D3/04
Filed: 1988-11-30
Abstract: Selon l'état de la technique concernant les moteurs à vent, tout module éolien engendre des turbulences et des vibrations néfastes au rendement et à la fiabilité. Par ailleurs, l'usinage et l'assemblage d'une multitude de pièces élémentaires réduisent considérablement la compétitivité du produit final. Dans la présente invention, on remédie à ces inconvénients, par la restructuration d'un module stato-éolien groupant seulement trois éléments coulés d'une seule pièce, une turbine à écoulement parabolique (1) tournant sur un socle (2) et protégé par un dôme en forme de demi-lentille (3). Ces trois éléments, de conformation complémentaire, procurent un rendement, une fiabilité et une compétitivité accrus.

Title: Motor vehicle torsion damper - has circumferential coil springs with internal guides and resilient bushes
Inventor: NAUDIN JACKY
IPC: F16F15/134
Filed: 1988-02-11
Abstract: The coil springs (35) act between the two sections of the flywheel to dampen vibrations and engine irregularities. Each spring is threaded over a square section rod (51). The rod is fitted with a resilient bush (57) also inside the spring. Each end of the spring is fitted with a flanged end stop (49). During the relative displacement of the two sections the spring is compressed until the end stops and central bush come into contact just before the spring coils close. ADVANTAGE - The spring is prevented from distorting laterally and wearing prematurely.

Patent FR-2674205-A1 (FR)
Inventor: PIERRE BOURGOGNE
IPC: B60T8/88
Filed: 1991-03-20
Abstract: Known anti-lock braking systems substantially extend braking distances. The systems are useful only in the event of skidding resulting from a difference in. The subject of the invention concerns the automatic activation of a vehicle's anti-lock system only when it is strictly necessary, that is at the onset of a skid and the deactivation of the anti-lock system as soon as skidding has ceased. The vehicles total braking capacity is thereby maintained in all circumstances, and the average braking distances of vehicles equipped with the basic anti-lock system are reduced to a considerable extent. To achieve this result, one or more acceleration meter(s) and, optionally, strain gauges as well as various sensors transmit data to a computer, enabling it to detect the beginning of the skid. In such an event, the computer automatically controls a switch which closes the anti-lock system control circuit, thereby activating it. As soon as skidding has ceased the computer cuts the circuit controlling the anti-lock system, thereby deactivating said system.
