Abstract: L'invention porte sur des calcitonines et des dérivés de calcitonines, comme ceux utilisés pour le traitement, par exemple, de l'ostéoporose, de la maladie de Paget ou de l'hypercalcémie. Les calcitonines et dérivés de calcitonines de l'invention sont caractérisés par un pontage des acides aminés présents en positions 17 et 21. Dans ce cas, grâce à un choix approprié des acides aminés présents à ces positions, il est possible d'obtenir un cycle de 18 ou 19 chaînons. Ce cycle permet d'obtenir une calcitonine modifiée présentant une meilleure stabilité de configuration et une plus grande activité. Un analogue de hCt (Ct humaine) particulièrement approprié, selon l'invention, est la cyclo-17,21-[Asp17,Om21]-hCt, possédant un cycle de 19 chaînons entre l'Asp17 l'Om21 ainsi pontés.

Granted: 2006-04-18
Abstract: Afin d'appliquer une impression amovible sur un conteneur tel qu'une caisse en plastic, la couche d'encre formant l'impression comporte sur l'un de ses côtés un agent de liaison qui va assurer son adhésion au conteneur. Cette couche est transférée sur le conteneur depuis un film de support sur lequel elle a été préalablement appliquée de son côté dépourvu d'agent de liaison. Cet agent de liaison possède des propriétés telles que, dans des conditions d'utilisation normales du conteneur, la couche d'encre va adhérer fermement audit conteneur. Dans des conditions prédéterminées autres que les conditions d'utilisation, l'agent de liaison et la couche d'encre peuvent être facilement séparés du conteneur. Ce système permet d'obtenir un conteneur possédant une impression d'une grande qualité qui peut être facilement remplacée par une autre impression.

Title: Method and apparatus for polishing ophthalmic lenses
Inventor: SAVOIE MARC Y
IPC: B24B37/00
Filed: 1999-01-27
Granted: 2003-04-15
Abstract: The invention pertains to an improved method, a lapping tool head and a lens polishing apparatus for carrying out the method, for polishing ophthalmic lenses. The apparatus has a lapping tool head, a flexible membrane covering a lapping portion of the tool head, and pump and nozzle for pumping abrasive slurry over the lapping tool head. The new method comprises the conventional step of imparting an oscillatory movement to the lapping tool head and contacting the lens surface with the lapping portion of the lapping tool head while an abrasive slurry is pumped over the lapping tool head. The improvement comprises the additional step of periodically undulating the membrane for imparting a wave in that membrane such that the abrasive slurry can flow between the membrane and the lens surface. The lapping slurry is efficiently moved over the entire surface of the lens for improving the quality of the lenses polished by this process.

Abstract: L'invention concerne un procédé de mesure de la résonance quadrupôle nucléaire d'un échantillon, dans lequel l'excitation appliquée à l'échantillon est effectuée de telle façon qu'on puisse obtenir des informations de phase et d'amplitude du signal de réponse, et dans lequel le signal est résolu en deux composantes. Notamment, si un paramètre tel que l'intensité de champ de radiofréquence varie en fonction de la position, cela peut donner une indication de la répartition de noyaux dans l'échantillon, de préférence à partir de la phase du signal de réponse. On peut également obtenir des informations de position en procédant à une mesure à partir de deux points de référence ou plus. Ce procédé peut être utilisé en imagerie. On peut utiliser les informations de phase pour améliorer le rapport signal/bruit susceptible d'être obtenu dans d'autres procédés dans lesquels seules les informations d'amplitude étaient disponibles antérieurement, par exemple en distinguant de vrais signaux de réponse à résonance quadrupôle nucléaire de signaux parasites.

Abstract: A hand-held, portable device recommends dynamically preferred speeds for stabilizing or reducing undesirable vibration such as chatter in a machining process. The device may be applied to machining processes such as turning, boring, milling and drilling which exhibit a relative rotational motion between the cutting tool and workpiece. The device measures in a safe, non-contact manner via a microphone the dominant audio signal component of the sound pressure emanating from the machining processes. Without prior knowledge of the machining process parameters or the dynamic characteristics of the machine tool or workpiece, the audio signal is conditioned and processed to determine the frequency component levels.      The rotational speeds which are more likely to lead to a stable machining process are calculated based on the number of teeth on the cutting tool and the identified dominant frequency of vibration. The dynamically preferred speeds are displayed as recommendations to the process operator or machinist.

Abstract: Disclosed is a method for producing a magnetic stimulation effect and/or a fake magnetic stimulation effect in a biological tissue.  According to the method, the real magnetic stimulation is effected by virtue of inducing an electromagnetic field in said biological tissue with a sufficiently strong field strength to essentially excite said tissue, and the fake magnetic stimulation is effected by virtue of inducing an electromagnetic field in said biological tissue with a field strength that is weaker than the electromagnetic field required for an essential excitation of said tissue. According to the invention, said electromagnetic field weaker than the electromagnetic field strength required for an essential excitation of the tissue is produced by the steps of inducing at least one first electromagnetic field in said biological tissue, and simultaneously, inducing at least one second electromagnetic field superimposed with said first electromagnetic field but so deviated by its direction from the direction of said first electromagnetic that the sum effect of said electromagnetic fields in the target area of said biological tissue remains weaker than the electromagnetic field required for an essential excitation of said tissue. Also an apparatus is described suited for implementing the method.

Abstract: A system and method provide a call service features in response to call control information conveyed by a monitored bearer channel in a telecommunications network. A bearer channel monitor captures the call control information and relays the information to a call control application server. The call control application server analyzes the call control information, and provides call control instructions to a call control node that operates in the telecommunications network to effect the call service. The call control node serves as one or more virtual switching points in the network to directly control call routing without disconnecting a called or calling party, unless required as part of a service feature. Control from a center of the telecommunications network provides rapid and efficient call control without use of edge devices or duplication of bearer channels in the network.
