Abstract: The apparatus of the present invention utilizes a bricklaying robot which comprises an automatic brick-handling or grabbing device fastened to the end of a main arm which is carried by a frame mounted on a work platform; and which is radially movable relative to the platform. Circular movement of the arm and of the grabbing device relative to the vertical axis of the work platform is generated as result of a rotation of the platform about this vertical axis. The present invention also utilizes a storage table which is mounted underneath the main arm of the robot, so as to be movable along a vertical axis and rotatable about the axis. The present invention further includes an automatic depalletizing mechanism comprising a pivoting arm, of which one of the ends is equipped with a brick-grasping device and the other end is mounted pivotally on a support sliding parallel to the main arm of the robot between two rails of the frame. This brick lining apparatus is less bulky than known prior art apparatuses and offers monitoring personnel a greater degree of safety.

Abstract: Ce procédé de réglage du retard entre stations dans un système de transmission d'informations utilisant dans un sens de transmission le principe dit d'A.M.R.T. peut être avantageusement appliqué lorsque le système comprend un grand nombre de stations relais en cascade. Une plage de réglage est imposée au retard à apporter à l'émission des données afin d'éviter des sauts d'informations pouvant provoquer des chevauchements à la réception desdites données. Le réglage du retard se fait en commençant par la station relais la plus proche de la station principale, puis la suivante, et ainsi de suite pour se terminer par le réglage de la station terminale concernée.

Abstract: A spinal implant has an elongate body (1) which is divided into two portions (5, 6) with mutually opposed contact surfaces (5A, 6A) and is for insertion into the joint space between two adjacent vertebrae. A cam device (3) or cam devices are movable between the contact surfaces to expand or increase the spacing between the body portions so as to increase the spacing between the adjacent vertebrae. 
     The implant has a porous external surface to facilitate bore and cartilage tissue growth therein. Alternatively, the external surface is smooth and coated with a bioactive material such as a hydroxyapatite, for example, tricalcium phosphate. In both instances bone, cartilage tissue and external surfaces of the implant are fused together to prevent migration of the implant. Advantageously, insertion of the implant requires a minimum incision in skin and cartilage tissue.

Abstract: The switching node is provided with at least one switching element, which has a number n of input lines (E1,...,En) and a number n of output lines (A1,...,An) which can be connected as required via a space switch (RK) to the input lines. A buffer memory (PS1,...,PSn) is allocated to each of the input lines, in which k data packets can be stored and which has m </= k outputs, via which m data packets can be fed simultaneously to the space switch which has mxn inputs and n outputs. The memory addresses under which the data packets to be forwarded are stored in the individual memories are stored, according to the address signals contained in the data packets, in queuing memories (AP1,...,APn) allocated to the output lines. The queuing memories can be activated cyclically from a central control unit (ZST) in order to prepare memory addresses. By means of memory addresses prepared in this way, the central control unit controls both the setting of the space switch (RK) and the output of data packets from the buffer memories (PS1,...,PSn).

Title: Procede de commande ameliore d'un moteur a induction a courant alternatif et dispositif prevu a cet effet

IPC: H02P27/04
Filed: 1988-03-11
Abstract: Le procédé et le dispositif décrits servent à commander un moteur à induction à courant alternatif à n'importe quelle vitesse du moteur y compris la vitesse zéro. La tension d'alimentation est modulée au moyen d'un signal de forme sinusoïdale avec une fréquence prédéterminée, de façon à produire un champ magnétique statorique et un courant rotorique. La tension d'alimentation (uS) subit une distortion, afin de conférer à la partie de magnétisation de la tension (VL) une forme sinusoïdale. Si cette condition est remplie, on obtient une compensation des erreurs dues par exemple aux propriétés de magnétisation non linéaire du fer au début de la saturation et les causes supplémentaires d'ondulation du couple moteur sont éliminées. La présente invention se rapporte à la commande en tension dudit moteur à induction malgré le fait que le couple soit produit par le courant traversant les enroulements. La distortion des tensions peut se produire de différentes manières et des tables de sinus et cosinus avec valeurs ajustées sont décrites. On donne ici une analyse mathématique complète du modèle dudit moteur à induction à courant alternatif, analyse qui comprend également les inductances de fuite au niveau du stator et du rotor.
