Abstract: The invention relates to a multi-chip computersystem with master-slave latches. It is known to provide all latches on all chips with two clock pulses, respectively. With the help of the latches the digital signals are pipelined through the logic gates on the chip. Due to tolerances, the edges which control the masters and the slaves have a skew. According to the invention, one of the two clock pulses is generated on the chip itself, respectively, by ANDing an auxiliary clock pulse with the other of the two clock pulses. This has the result, that the above mentioned edges of the two clock pulses occur almost at the same time with the consequence that the frequency of the clock pulses can be increased.

Abstract: Gas charged with organic impurities is purified in two stages. Impurities still present after the first stage are burned in the second stage, producing the energy needed for operating the first stage and thus obviating need for external power supply. The first stage is pref. a cooling stage with a compressor using combustion energy from the second stage, followed by condensation. Gaseous material may pass through a semi-permeable membrane in the first stage, using pressure derived from a heat engine. In an alternative, the first stage washes the gas with polyethylene glycol ether to separate impurities by absorption. Any surplus second-stage energy may be used for external purposes, e.g. current generation.

Abstract: The invention relates to splinter generators with a casing prefragmented to obtain a focused cluster of splinters. It relates more particularly to the uncoupling of the splinters of a prefragmented casing, in order to prevent any welding, on the one hand between the elements limiting the explosive charge and the splinters and on the other hand between the splinters of each of the adjacent rings or turns constituting the splinter-generating casing. This welding usually limits the effectiveness of the focused cluster of splinters. The invention involves covering with a layer of a material (9) the outer periphery of a shell (6) laterally limiting the explosive charge and coating the splinter-generating casing (7) positioned on the outer periphery of the shell (6) with a layer of another or of the same material. These materials have the characteristic of possessing a mechanical impedance sufficiently different from that of the splinters to prevent the various welds caused by the shock wave which emanates from the detonation of the explosive charge. <IMAGE>

Abstract: On prévoit une broche à haute vitesse comprenant un rotor entraîné par un moteur électrique et doté de tourillons coniques (19, 20) montés dans des paliers coniques en caoutchouc (22, 23). De l'eau lubrifiante s'écoule dans lesdits paliers à travers des ouvertures calibrées (49, 54) pratiquées dans les tourillons, et s'écoule depuis lesdites ouvertures à travers des rainures hélicoïdales inverses (56, 58) dans les tourillons qui présentent une coupe transversale en réduction. L'eau qui s'écoule à travers le rotor refroidit celui-ci ainsi qu'un outil saisi par la pince de serrage (12). Des joints en caoutchouc (83, 87) disposés autour de l'arbre du rotor (17) s'usent jusqu'à ce qu'un écartement zéro se réalise lors du rodage de manière à limiter l'eau qui se décharge des paliers. De l'air comprimé introduit dans la broche coopère avec lesdits joints afin d'empêcher les fuites d'eau. Ledit air comprimé réagit également contre une vessie (114) disposée de manière à imposer une charge terminale sur un des paliers, lequel est mobile, de sorte que ledit palier se déplace vers son tourillon. On varie les efforts de manière à augmenter la charge terminale du palier lorsque la vitesse du rotor augmente. La pince de serrage est caractérisée par des cônes autoporteurs (136, 139) pour se retenir dans une position fermée, des surfaces de cames (148, 149) l'aidant à s'ouvrir vers une position libérée. Un organe détachable retient la pince de serrage de sorte que l'on peut l'enlever et ainsi retirer une tige fracturée.

Title: Prosthesis for preventing the gastric reflux in the oesophagus.
Inventor: GODIN NORMAN
IPC: A61F2/00
Filed: 1990-07-16
Abstract: The prosthesis is configured like an anti-return valve arranged preferably in the area where the oesophagus and the hiatal hernia meet. Said valve is comprised of a tubular part (7) associated with an annular fixing element (8). The tubular part flatens progressively to form two joined lips (9, 10). It is possible to form said valve with a wall thickness which increases from the free end of the lips (9 and 10) towards the annular fixing part (8) in order to avoid an easy returning under the effect of the surging pressure. During the passage of the alimentary bolus, the lips (9, 10) are spaced apart and joined again owing to their natural elasticity. A metal wire (16) embedded in the annular fixing part (8) is used for the radiologic marking.

Abstract: Dans des directions assistées hydrostatiques, il se produit des erreurs de synchronisation entre un mouvement de rotation du volant de direction et la déplacement des roues dirigées, en raison de fuites intervenant au niveau de la soupape de direction. Le flux d'huile quittant une pompe manuelle n'est donc pas entièrement disponible dans le servomoteur. L'huile de fuite manquante ne peut être remplacée que par rotation supplémentaire du volant. La fuite dans la soupape de direction se forme principalement entre les rainures HD (24; 25) et les rainures ND conduisant au réservoir (22 ou 23), rainures entre lesquelles se produit une forte perte de charge lors du braquage. C'est la raison pour laquelle il est prévu entre les rainures HD et les rainures ND, des rainures dites de blocage de pression (42 ou 43). Selon l'invention, ces rainures de blocage de pression sont reliées, par l'intermédiaire de canaux (48 ou 50) aux faces frontales d'un alésage (51). Dans la partie médiane de cet alésage (51) débouche un canal (53) relié à une rainure P (21) de la pompe (14). L'alésage (51) renferme un piston (52) qui relie en ses deux positions de fin de course, le canal (53) à la rainure de blocage de pression (42 ou 43). Lors d'un mouvement de braquage, la rainure de blocage de pression (42 ou 43) de la rainure HD conduisant la pression (24 ou 25) peut ainsi être toujours sollicitée par la pression élevée de la pompe (14). Grâce à cette disposition, les pressions dans la rainure HD (24; 25) et dans la rainure voisine de blocage de pression (42 ou 43) peuvent être maintenues sensiblement à la même valeur. Un suintement de l'huile de fuite de la rainure HD (24; 25) vers la rainure ND (22 ou 23) peut ainsi être supprimé.
