Granted: 2000-01-25
Abstract: La présente invention se rapporte à un système tomographique informatisé qui mesure l'épaisseur et la position au bord du laminé à chaud. Des rayons X produits par deux sources de rayons X (10a, 10b) traversent l'échantillon (16) que l'on est en train de mesurer et sont dirigés vers une pluralité de détecteurs (17) de rayonnement. Les détecteurs de rayonnement mesurent l'atténuation des rayons X provoquée par l'échantillon (16). Les niveaux d'atténuation détectés par chaque détecteur correspondent à chaque emplacement physique des détecteurs. Ces données sont recueillies lorsque chaque source de rayons X (10a, 10b) éclaire les détecteurs (17) de rayonnement. On effectue, si nécessaire, une triangulation ou une moyenne des données recueillies pour déterminer les dimensions et la position de l'échantillon mesuré (16).

Abstract: Agencement de circuit de synchronisation compris dans une unité de multiplexage/démultiplexage (1) recevant un train binaire coordonnée à un paquet de données. Les valeurs et les positions binaires au sein d'une partie prédéterminée d'une séquence de bits consécutifs de chaque paquet de données transmis sont sélectionnées en permanence de sorte qu'un calcul de contrôle prédéterminé donnera une valeur prédéterminée (par exemple "0"). Une séquence de bits consécutifs correspondant à la partie prédéterminée d'une séquence de bits consécutifs et appartenant aux paquets de données reçus respectifs est évaluée de manière à déterminer dans quelle mesure le calcul de contrôle donne la valeur prédéterminée. En cas d'accord, on présume que la limite entre deux paquets de données proche l'un de l'autre est déterminée par l'intermédiaire de la séquence de bits de la partie prédéterminée d'une séquence de bits consécutifs. Chaque train binaire en entrée est synchronisé par l'intermédiaire d'un bloc de commande ou d'une logique de commande (4, 9) par introduction dans un convertisseur série-parallèle (3) pour les trains binaires respectifs d'un retard de temps correspondant au synchronisme.

Abstract: Système de multiplication de plantes et procédé associé destiné à favoriser la croissance de tissus végétaux pour en faire de petits plants. Ledit système comprend des enveloppes faites de membranes semi-perméables renfermant la totalité du matériel végétal. Lesdites enveloppes sont généralement translucides et perméables aux gaz et aux liquides, tout en étant imperméables aux contaminants biologiques. Les tissus végétaux qui proviennent de plantes mères se placent dans les enveloppes où ils subissent une croissance hétérotrophe. Lorsque le plant est capable de photosynthèse, les enveloppes peuvent être transférées dans une serre où elles sont placées sur des claies en vue d'une croissance photoautotrophe, où elles sont exposées à la lumière et à des gaz, et reçoivent l'eau et les nutriments liquides qui en optimisent la croissance. Un dispositif central de contrôle peut être adjoint à l'ensemble pour automatiser la circulation des fluides alimentant les claies et en partant, et surveiller le fonctionnement du système. On peut prévoir la circulation sur les claies et autour des enveloppes d'un désinfectant détruisant les contaminants biologiques et maintenant un environnement aseptique.

Abstract: An adjusting mechanism for adjusting the position of a first structural member relative to a second structural member. The mechanism is particularly well suited for use as a mechanism for adjusting the vertical or lateral position of a chair back or armrest relative to a chair seat and is adapted for one-handed adjustment. The adjustment mechanism has an arm mountable to a first structural member and slider securable to a second structural member that slidably engages the arm. A ratchet rack is on the arm and a pawl is supported by the slider, which is adapted to engage the ratchet rack, permitting only one direction movement of the slider along the arm. One of the pawl and slider has a cam guide, which has a portion substantially transverse to the ratchet rack and a portion extending from the substantially transverse portion in a direction substantially parallel to the rack. The other of the slider and the pawl has a cam follower extending therefrom. The cam follower, slidably engages the cam guide. A biasing member resiliently pushes the pawl into engagement with the ratchet rack, and forces the cam along the substantially transverse portion of the cam guide, away from the substantially parallel portion of the cam guide. One of the arm and the paw has a first camming surface, the other of the arm and pawl has a first abutting surface. When the pawl first surface is pushed into abutment with the arm first surface, the cam follower is forced along the substantially transverse portion of the cam guide into the substantially parallel portion of the cam guide. The pawl is then disengaged from the ratchet rack, thereby allowing bi-direction motion of the slider along the arm.      The arm has a second surface such that when the pawl is pushed into abutment with the second surface of the arm, the cam follower is pushed into the horizontal portion of the cam guide, re-engaging the pawl and ratchet rack.

Abstract: A vibrato assembly (20) for stringed instruments makes slight and rapid changes in the pitch of the tone produced by stringed instrument. Previously known vibrato assemblies use knife-edge hinges or rolling ball bearings to produce these variations. The vibrato assemblies (20) described herein use flexure bearings (32) to produce variations in the tension of the strings and thereby the pitch of the tones. These flexure bearing (32) vibrato assemblies (20) have the advantages of high strength, zero operational noise and tumble, and virtually zero friction and hysteresis. Additionally, flexure bearing (32) vibrato assemblies (20) provide a robust path between the instrument and the strings resulting in improved tonal quality, range, and sustain.
