Title: Selectively hardening internal surface of cylinders
Inventor: RABINO EDOARDO
IPC: F02F1/18
Filed: 1985-09-20
Abstract: Method consists of guiding a laser beam into the cylinder and deflecting the beam onto the side wall to bring about the heat treatment, and constantly measuring the temp. of the exposed area and adjusting the parameters of the laser beam in response to the temp. in order to control the heat treatment. The temp. measuring is carried out by reflecting infrared rays from the edges of the treated area to an infrared probe via a mirror and optical fibres.  The laser beam is deflected onto the cylinder by deflector which is cooled by coolant running through conduits.  The glass fibres run in a tube which is cleaned and cooled by air drawn through the tube. The support part has a tube element through which the beam runs and an outer tube (15) which rotatably supports the inner tubes enabling its movement in an axial direction.

Title: Dispositif pour artifice pyrotechnique a vitesse de descente reduite
Inventor: MORET CLAUDE
IPC: F42B4/28
Filed: 1986-01-21
Abstract: Le dispositif permet de ralentir et de régulariser la vitesse de descente d'un artifice pyrotechnique 5, pour qu'il puisse être opérationnel près du sol pendant une durée satisfaisante. On utilise un parachute muni d'une voilure 1 auquel est suspendu l'artifice. Une jupe 6 est cousue à la périphérie de la voilure pour constituer un réservoir de gaz chauds résultant de la combustion de l'artifice, de manière à obtenir un effet de sustentation analogue à celui utilisé dans une montgolfière. Une circulation des gaz, assurée par l'intermédiaire d'ouvertures 7 et de godets 8, évacue ainsi les gaz vers le bas, et permet de maintenir une température constante à l'intérieur du réservoir. Des voiles latérales 9 peuvent être cousues sur la jupe, leur forme étant conçue pour faire tourner l'ensemble et pour remonter le vent latéral. On prévoit de revêtir la face intérieure de la voilure de forme parabolique d'une surface réfléchissante aluminisée pour augmenter la réflexion des rayons lumineux vers le sol. Une application est prévue dans le domaine militaire, plus particulièrement, pour le parachutage des artifices éclairants ou infrarouges. (CF DESSIN DANS BOPI)

Title: Device actuating moving bodies using wind energy
IPC: F03D9/00
Filed: 1986-12-01
Abstract: It makes it possible to propel, lift, stabilise or control any sea or land moving body 7 so as to obtain its self-propelled movement. It includes a rotor 1 of the helicopter type whose non-vertical shaft 2 revolving freely in a hub 3 which can be oriented 5 is fitted with a brake 4. Self-rotation under the action of the wind generates a gyroscopic effect and an axial aerodynamic thrust which are regulated by the inertia, the orientation of the rotor, and the setting of the pitch of the blades 8. The propulsion and lift forces are applied to the moving body in accordance with the direction of the shaft by a mast 6 which can pivot 24 or an arm 9 which is oblique so as to combat overturning. The orientation of the rotor is direct, or induced by cyclic pitch variations. All the adjustments can be effected remotely 15 with or without automatic control and computer. The rotor, possibly coupled 21 to a machine producing 28 or receiving 29 accumulated energy 22, gives autonomy. The device according to the invention is particularly intended for actuating all boats and scale models.
