Abstract: Procédé destiné à préparer la surface de fixation d'un corps en céramique dentaire afin qu'elle puisse être subséquemment fixée à une dent avec, par exemple, des céments à base de résine et de polyalcénoate de verre, et consistant à déposer, selon une technique de dépôt en phase gazeuse, et directement sur la surface de fixation du corps en céramique, un revêtement fortement adhésif d'une substance inorganique telle que l'oxyde d'étain en une épaisseur idéale de moins de 2 microns. Ce revêtement réagit avec le cément pour produire une fixation chimique durable qui n'est pas soumise à une dégradation chimique dans l'environnement buccal et qui ne nuit pas à l'esthétique de la restauration dentaire associée.

Abstract: On décrit l'oxydation électrochimique d'un composé précurseur N-hétérocyclique à insuffisance de pi, possédant un groupe organique oxydable lié par une liaison carbone-carbone. Ce composé précurseur est au moins un peu hydrosoluble. L'électro-oxydation préférée s'effectue au niveau d'une anode effective et dans un milieu qui est essentiellement constitué d'eau, d'acide carboxylique et du composé précurseur. On préfère les électro-oxydations des bases pyridiniques et quinoléiques substituées, et un mode préféré de réalisation assure une synthèse électrochimique pratique de la niacine à partir de la méthylpyridine-3.

Abstract: L'invention se rapporte à un système de traitement d'images numériques qui sert à numériser et à stocker les images (421) d'un film photographique numérisé selon l'orientation dans laquelle elles ont été fixées sur le film, afin d'éliminer la nécessité de mettre physiquement en rotation l'analyseur de film par rapport au film pour les images verticales, ce qui permet ainsi de réduire considérablement la complexité et le coup de l'analyseur. En lieu et place, chaque fichier d'images stockées (421) comporte un fichier de commande de présentation associé (422), lequel contient les informations relatives à l'orientation et au format d'images, de sorte que le dispositif d'image connaît la façon dont chaque image a été mémorisée sur la base de données servant de support aux images numériques, constitué par exemple par un disque compact. Lors de l'introduction du disque dans un dispositif de lecture en vue de mettre en marche un dispositif d'affichage de sortie, tel qu'un moniteur TV couleur, le dispositif de lecture est immédiatement capable de décoder les informations de commande de lecture pendant l'extraction de l'image numérisée, pour que l'image soit affichée selon une orientation droite et selon le format correct pour le dispositif d'affichage en question.

Abstract: Molded articles of high-purity alumina fibers, which are porous materials in which heat resistance is high, and in particular, deformation and linear shrinkage in heat cycles at a temperature more than 1700°C are small, can be obtained by a method comprising the steps of spinning a spinning solution containing an alumina fiber precursor as the main component to obtain precursor fibers, prefiring these precursor fibers at 400 to 1000°C to form prefired fibers, and then molding and calcining these prefired fibers. 
     Sintering between the fibers can be achieved at a relatively low temperature, and in particular, even when no inorganic binder component is added, the molded articles of high-purity alumina fibers can be obtained by a simple process.

Abstract: When time-division multiplexed digital data signals are to be demodulated, symbols in a time slot and symbols in the next time slot are stored in memory. The digital data signal in each time slot includes a training sequence. Channel estimators extract channel information regarding stored signals from the signals themselves as well as from the training sequences in succeeding time slots and output the channel information to a channel information generator which combines the channel information from the channel estimators into channel information regarding the signal in the time slot. A demodulator receives the combined channel information and the stored signals and demodulates the signal in the time slot.

Abstract: In a method for arranging flat elements with respect to a reference device, especially punching dies or the like, and for arranging embossing plates to form an embossing original outside a punching machine by means of a camera and a display screen assigned to it, the camera position is set over a locking-up frame and a marking on one side of the locking-up frame and adjusted until the image of the camera on the display screen coincides with a line of a cross wire, whereupon the camera is guided over a second marking, approximately aligned with the first, at the other end of the locking-up frame, and subsequently the rear part of the locking-up frame is displaced at right angles to the first direction of travel until the image of the second marking on the display screen coincides with that cross wire line. In addition, the punching die is to be enclosed, and in this case the parallelity relative to the first direction of travel is to be set via the cross wire line; after the arrangement of the punching die, the embossing original is arranged thereabove with the use of a supporting/backing plate provided with markings. <IMAGE>

Abstract: A two position straight line motion actuator utilizes a double ended pneumatic spring to provide most of the energy required to transit back and forth between the two positions. The actuator is held in its initial position against the force of the pneumatic spring (6) by hydraulic pressure applied to a latching piston (2). Transition from the initial or first position to the second position is initiated by opening a flow path around the latching piston to cancel the effects of the high pressure latch thus allowing the air spring (6) to power the actuator to its second position. As the actuator moves toward the second position, the second air spring (17) dampens actuator motion converting the kinetic energy of the actuator moving portion into potential energy in the form of highly compressed air, thus cocking the pneumatic spring (17). Return of the actuator is blocked by the fluid latch. Upon command, a valve (9) opens the flow path around the latch, allowing the latch to release the actuator to return to its initial position. Supplemental hydraulic pressure is valved into the latching chamber (14) during the latter part of travel of the moving portion of the actuator to overcome system friction and to assure that the actuator moves fully to its initial position. Both the speed and the distance travelled by the moving actuator portion may be controlled by pre-pressurization of the air chambers.
