Abstract: Cette invention concerne une roue élastique comprenant un disque (1) doté d'une sous-jante (2) et d'une jante (3) qui supportent un pneu selon un montage pivotant. La partie en saillie (5) de section généralement trapézoïdale dans le sens de l'axe de la roue est formée dans un creux de la jante (3). Une paire d'éléments en caoutchouc élastique (6) sont disposés de façon annulaire entre les surfaces extérieures d'une paire de parties latérales (4a, 4b) obtenues par torsion des deux côtés de la sous-jante (2) selon un angle aigu et la surface périphérique intérieure de jante de la partie en saillie à la forme généralement trapézoïdale (5). Les vibrations sont absorbées à la fois par la déformation de cisaillement et la déformation en compression des éléments en caoutchouc élastique (6), ce qui améliore le confort ainsi que l'amortissement des vibrations et des bruits faibles ou forts, l'amortissement du bruit étant particulièrement efficace dans la région des hautes fréquences de 100 Hz ou plus.

Abstract: La présente invention concerne un procédé de dégradation du N2O lors de la production d'acide nitrique par mise en contact des gaz d'échappement à base de N2O s'échappant de la colonne d'absorption, avec un catalyseur. Ledit catalyseur comprend au moins un composé cobalt oxydique et au moins un composé magnésium oxydique choisis parmi les composées de ce type qui permettent une transformation de N2O en azote et oxygène gazeux.

Au moins 30 % des atomes de cobalt contenu dans le catalyseur se trouvent à l'état trivalent. La préparation du catalyseur fait intervenir le mélange à sec des composés cobalt oxydiques et des composés magnésium oxydiques ou de leurs précurseurs respectifs qui se transforment en composés oxydiques par recuit, et la compression du mélange réalisée en même temps que l'expulsion d'eau, de sorte que le catalyseur obtenu présente la densité volumique souhaitée.

Abstract: L'invention concerne des instruments manuels comprenant un dispositif d'actionnement utilisé pour actionner un outil monté distalement par application d'une force radiale sur la globalité de la circonférence dudit instrument (par exemple, omni-actionnable). De préférence, le dispositif d'actionnement (10-1) comporte une pluralité de leviers d'actionneur en forme de L généralement espacés circonférentiellement (20) qui forment des surfaces de support arquées respectives (22-1) le long des zones correspondantes de bords extérieurs, et un anneau de rétention (22) liant circonférentiellement lesdits leviers autour des zones correspondantes de bords extérieurs. Cet anneau de rétention constitue, de préférence, une surface guide arquée stationnaire interne (20-3) accouplée de manière adaptable aux surfaces de support (22-1) desdits leviers. La force radiale appliquée aux sections de bras s'étendant dans le sens proximal desdits leviers entraîne le déplacement coulissant des surfaces de support le long de la surface guide dudit anneau de rétention. Ainsi, une telle force radiale peut être translatée en mouvements longitudinaux d'une broche d'actionnement allongée (18) entre des positions rétractées et dilatées correspondantes. En utilisant un outil co-agissant avec la broche d'actionnement, un chirurgien peut actionner ledit outil, comme cela est nécessaire, en appliquant une force radiale à n'importe quel endroit autour de la circonférence du dispositif d'actionnement.

Title: Hydraulic elevator with an accumulator
Inventor: MOSER DANIEL
IPC: B66B9/04
Filed: 2001-08-09
Granted: 2009-01-27
Abstract: The invention relates to a hydraulic lift with an accumulator (16). According to the invention, a pump (13) is situated between the hydraulic drive (2) and the accumulator (16), this pump being driven by a motor (14) and providing a means for conveying hydraulic oil from the hydraulic drive (2) to the accumulator (16) and vice versa without the presence of control valves which influence the flow of hydraulic oil, such as proportionally pilot-operated valves. Since the pump (13) is subjected to the pressure PZ in the cylinder line (11) and the pressure PS in the accumulator line (15), the motor (14) of the pump (13) only has to work against the differential pressure and in certain operating states, can even function as a generator and release electrical energy through a power output device (23) controlling it. This reduces the energy requirements for operating the lift. The speed of the car (1) is controlled or regulated through the control of the motor (14) alone by a control and regulation device (25), through the power output device (23).

Granted: 2007-05-01
Abstract: A data processing apparatus constituting a low-cost audio/video data transmission and reception system is disclosed. A reception buffer monitoring circuit 21 monitors the size of receiver data being accumulated in a reception buffer 6. When the size of accumulated data is found to become higher than a high threshold, the circuit 21 causes a reception clock generation circuit 8 to generate a reception clock with a higher frequency. When the accumulated data size becomes lower than a low threshold, the reception clock is generated with a lower frequency. Based on the reception clock fed from the reception clock generation circuit 8, an audio/video decoder 7 decodes the audio/video data coming from the reception buffer 6. This invention applies advantageously to a television transmission and reception system for transmitting and receiving TV broadcast signals.

Granted: 2009-05-19
Abstract: A wireless control device (10) includes a small, lightweight housing (22) worn by an operator (20), for example on the operator's wrist, and a controlled device (24), for example a personal computer. Several optical emitters (32), preferably light emitting diodes operating in the infrared range, and several optical detectors (36) are provided on the housing. At least one x-axis emitter-detector pair operates to detect an x-direction of a pointing motion or gesture, and at least one y-axis emitter-detector pair operates to detect a y-direction of a pointing motion or gesture. This motion can then be used to cause a response in the controlled device (24). For example, angles of the operator's hand at the wrist can be interpreted to induce motion of a cursor on a computer display. The device may also include a motion sensor (40), an environmental condition sensor (42), or a voice recognition sensor (43), and can also be adapted for gesture recognition and image scanning applications.

Abstract: L'utilisation de bassins pour déchets agricoles constitue actuellement le procédé principal de stockage de grandes quantités de sous-produits du bétail, tels que du fumier. Des sous-couches d'argile sont les moyens les plus couramment utilisés pour recouvrir le fond des bassins de stockage dans le but d'empêcher le suintement des déchets. Ces sous-couches d'argile qui constituent un moyen de garniture économique possèdent une conductivité hydraulique inférieure à 1x10?-7¿ cm/s. Le confinement correct des déchets dans ces bassins de stockage est un point critique pour éviter une contamination ultérieure des eaux souterraines locales. Une sonde de conductivité hydraulique a été conçue pour pallier aux aspects négatifs des procédés actuels mis en oeuvre pour déterminer la conductivité hydraulique. Cette sonde comprend un logement conçu pour être introduit dans le sol, un moyen de génération d'un gradient de potentiel électrique permettant de générer un gradient de potentiel électrique dans le sol et un moyen de détection de la pression permettant de mesurer les changements de pression dans le sol.

An active window (92) underlying a display window (100) is used to track user inputs to the control panels. Smart graphics processing (42) translates the user inputs into data elements that are sent to a full-scope simulation (48), and simulation conditions are returned and used to update the display of the control panels and the visual representation of the environment.
