Title: Procédé et dispositif de communication pour véhicule utilisant des radars
Inventor: BENSATOR SALEH
IPC: H04W4/46
Filed: 2022-02-09
Abstract: La présente invention concerne un procédé et un dispositif de communication mis en œuvre par un premier véhicule (10) embarquant un système de radars à ondes millimétriques. A cet effet, des informations de positions de deuxièmes véhicules (11 à 13) obtenues via la réception de données émises selon un mode de communication de type véhicule vers véhicule, dit V2V, sont comparées à des informations de positions de troisièmes véhicules (11 à 14) obtenues d’un radar (101) du premier véhicule (10). Le résultat de la comparaison permet de sélectionner une partie des troisièmes véhicules (11, 12, 13). Un faisceau de communication particulier (110, 120, 130) ayant pour origine le radar (101) est générée par filtrage spatial pour couvrir chaque véhicule sélectionné (11, 12, 13) et établir une communication en V2V via ce faisceau de communication particulier.

Patent FR-2220775-A1 (FR)
Title: Dispenser providing measured quantities of liquid - a graduated piston useful for measuring medicines with simple valving arrangmts.
IPC: G01F11/02
Filed: 1973-03-07
Abstract: The dispenser is a bottle with a cylinder and outlet tube passing through the centre of the stopper. A piston with a graduated shaft works inside the central cylinder to pump liquid into the outlet tube and through a nozzle into any other container. Simple valving arrangements allow the outlet tube to remain full and prevent the liquid syphoning back into the dispenser. This makes the dispenser accurate for small quantities and hygienic in use. The valves allow the cylinder to refill on the back stroke of the piston.

Title: Method of testing railway buffing systems - wagon is pushed down support blocks to build up required speed
IPC: B61J3/02
Filed: 1973-08-30
Abstract: The moving wagon (20) is placed on two supports (3), one per wheel and placed on the rail (1). Each support has a horizontal part (31) and a part (32) sloping down to rail level. The height and slope determines the speed of the wagon when it is pushed. The wagon to be tested (21) is placed near the ramps. There are brake shoes to stop the moving wagon (20) very quickly. Similar brakes stop the tested wagon from moving very far. The buffing force can be varied by varying the height of the supports (3). Typically, the wheels of the moving wagon are raised by vertical rams and the supports pushed under the raised wheels by a horizontal ram.

Title: Glass melting tank - with barrier across the central part of the homogenising zone, to turn back the surface glass layer
IPC: C03B5/187
Filed: 1974-02-22
Abstract: Glass is wetted in a tank with a fusion and refining zone and a homogenisation zone in the middle of which currents of molten glass form, both in the surface region where the currents flow forwardly aay from the hottest area and in the the deeper parts of the bath converging towards this hotter zone. The veins of glass in the central regions of the surface are caused to return and join with the deeper veins of glass by vertical barriers depending from the roof while the veins of another glass at the sides of the tank are allowed to pass unimpeded. The glass in surface return region is mixed to cause it to rejoin the lower levels. The quality of the glass produced is improved since the side currents are somewhat cooler than the centre currents of glass on the surface.

Title: Air-driven turbine in buoy - is designed to turn in same direction both during air blowing and suction phases
IPC: F03B13/24
Filed: 1974-04-25

Two turbine stators (31, 32) are arranged at the respective axial sides of the rotor blades so that air passing through the turbine in either axial direction acts on the rotor blades in the same circumferential direction. The airflows are produced when during the tilting of the buoy there is a rise and fall in the level of water in the upper end of a tube whose lower end is open to the sea. The generator feeds a navigation light.
