Abstract: Un système (10) de compensation de cisaillement du vent pour avion utilise des informations d'inclinaison longitudinale dérivées de manière inertielle pour informer (12) le pilote sur l'angle d'inclinaison longitudinale optimum permettant l'ascension maximale en conditions de cisaillement de vent. Le système (10) utilise un modulateur (22) de référence d'inclinaison longitudinale recevant une caractéristique d'avertissement de décrochage provenant du système d'avertissement de décrochage (16) pour réduire l'angle de guidage (12) d'inclinaison longitudinale lorsqu'apparaît un avertissement de décrochage, de manière à réduire la possibilité de décrochage de l'avion dans des conditions de diminution de performance telles que des vents arrière et des conditions de panne moteur. Ledit système utilise des informations d'inclinaison longitudinale dérivées de manière intertielle plutôt que des informations d'angle d'attaque dérivées de la masse d'air afin d'éviter les phénomènes transitoires dans le signal de la palette de détection d'angle d'attaque, provoqués par des turbulences d'air rencontrées pendant le cisaillement de vent, et pouvant provoquer des oscillations introduites par le pilote autour de l'axe d'inclinaison longitudinale.

Abstract: Une structure (24) de cloison étanche circulaire à lignes de rupture utilisée dans un moteur de fusée à étages multiples pour missiles ou similaire comprend un disque (34) soutenu par un organe de support (36) à ouvertures multiples. Le disque comprend une série de saillies (54) qui forment des bosses de forme correspondant à celle des ouvertures (52) de l'organe de support. Les saillies sont formées dans le disque sous une pression supérieure à la pression que supporte le disque soutenu. Des lignes de rupture (42, 44) du disque alignées avec des segments de support (56) de l'organe de support ajouré permettent au disque de se rompre et de s'ouvrir sous une pression sensiblement inférieure à sa résistance aux pressions postérieures. Cette structure de cloison étanche résiste à des pressions postérieures statiques manométriques dans une plage comprise entre 2 000 et 10 000 psi mais s'ouvre entièrement vers l'avant sous une pression statique manométrique ne dépassant pas 100 à 400 psi.

Abstract: A hip-joint cup for cementless implantation into the acetabulum of the hip, consisting of an elastic cup support, which has the shape of an essentially hemispherical shell and can be fitted with positive locking into the appropriately prepared bed of the acetabulum, is to be developed so that it fuses more quickly with the bone substance of the hip following its implantation and, even in the case of considerable stresses, a relative movement between the cup support and the acetabulum is prevented. This is achieved by virtue of the fact that the cup support (1) has its greatest rigidity in the area (2) directed upwards (craniad) in the implanted state, whereas in the downward direction (caudad) the elasticity of the cup support (1) increases, by means of the fact that on the one hand the wall thickness of the cup support (1) is greatest in the upwardly directed area (2) and decreases in the direction towards the lower area (3). There are additionally provided in the area of the cup support (1) of increased elasticity, at different distances from the equatorial plane (6), two or more incisions (11, 12, 13) extending parallel or at least approximately parallel to the equatorial plane (6) (Fig. 2).

Abstract: A nonvolatile memory system for one of a multiple of values includes a memory cell having an input terminal, an output terminal, and a control terminal. The memory cell (140), which may be an EEPROM, stores nonvolatile electric charge, and establishes a voltage threshold between the input terminal and the output terminal which influences a current therebetween, the threshold having a level which is dependent upon the amount of the electric charge stored by said storing means. A writing circuit is connected to the input terminal, and is responsive to an input data signal having a value selected from among at least three values, for applying electric charge in an amount corresponding to the value of the selected data signal, to the input terminal for storage in the memory cell (140). A reading circuit is provided to measure the value of the voltage threshold between the input output terminals, and to output an output data signal having a value which corresponds to the measured value of the threshold voltage. In its preferred embodiments, the system is an electrically erasable programmable read only memory system which can store multiple values in a single memory cell.

Abstract: The transfer device is intended to conduct an electric current and a pressurized air current between a feed coupling (4) and the handle (3) of a dental instrument, the latter being able to pivot about a longitudinal axis (xx') common to the two parts. For this purpose the device comprises at least one pair of cylindrical electrodes (14, 37) for the current and ducts (20, 39) for the air. One of the electrodes (14) is disposed at the bottom of a cavity (10) of the handle (3) and close to the longitudinal axis (xx'). The other electrode (37) is similarly disposed in a cavity (34) of the coupling (4), the two electrodes fitting into each other in order to form a contact between them. One of the ducts (39) is formed in the coupling (4) and the other duct (20) in the handle (3), these ducts respectively opening into the cavities (34, 10) of the coupling and of the handle in order to allow the air to flow in the cavities and around the electrodes. The arrangement of the electrodes in the cavities ensures their protection from shocks when the instrument and the coupling are separated, while the air flow allows evacuation of moisture which could be present in the cavities and on the electrodes. <IMAGE>
