Abstract: To remove, in particular, worn coatings (12) from double bottom plates (10) quickly and automatically, preferably three removing devices (17) with motor-driven separating knives (18) are built into an apparatus (13) which has, underneath the removing devices (17), a slide (29) with mountings (31) for the double bottom plate (10) to be processed. The slide (29) can be reciprocated by motor transversely to the separating knives (18) of the removing devices (17) or parallel to the longitudinal axis of the apparatus (13). The removing devices (17) are mounted on a receiving plate (21) so as to be pivotable in each case about a horizontal axis (19). The receiving plates (21) are, for their part, mounted spring-loaded on a transversely extending, portal-like frame part (15), so as to be movable to a limited degree in the direction of the longitudinal axis of the apparatus (13). The slide (29) is reciprocated via a travelling nut (38) by means of a threaded spindle (39) which is mounted on the frame (14) of the apparatus (13) so as to be rotationally movable, but axially fixed and is driven alternately in both directions of rotation.

Abstract: The invention relates to a horizontal deflection stage which is provided with a picture width control. An adaptation of the respective desired picture raster to the screen size and a stable picture width with changing horizontal frequency can be achieved by the fact that the charging choke (LS) of a horizontal deflection stage has applied to it a horizontal-frequency pulse width signal (U) which is determined by a pulse width controller (PR) by comparing a controlled variable (lp) proportional to a deflection current (Ia) with a reference variable (UR) proportional to the picture width. The invention is applied in television engineering. <IMAGE>

Abstract: The invention relates to hip joint prostheses which are anchored in the bone tissue by means of mesh surfaces (4) and which have a metallic supporting element (1, 11). The elastic mesh (10) arches outwards in the direction of the bone tissue (2) and is connected via its edges to the metallic supporting element (1, 11). When the prosthesis is inserted, the mesh (4) yields transverse to the direction of insertion and follows the wall of the bone cavity. Arranged under the mesh are cavities (5) in the supporting element (1, 11), which cavities (5) are filled in the inserted state with bone cement (8). By virtue of the fact that the mesh (4) is substantially impermeable to pasty compositions, there is, upon injection of bone cement (8), an extensive ramification of the bone cement in the area of the mesh (4), while the mesh (4) bears on the side of the bone over wide areas and affords a satisfactorily structured surface for the incorporation of bone tissue. Undercut depressions in the bone are also lined in this way with mesh surfaces.

Abstract: L'invention se rapporte à un appareil de formation d'image par transfert thermique, qui utilise un nouveau procédé de régénération d'une feuille d'encre. La feuille d'encre comporte une couche de base transparente servant également de couche diélectrique, une couche d'encre et une couche conductrice transparente disposée sur le côté de la couche de base opposé à la couche d'encre. Lorsqu'une tension de polarisation est appliquée à une encre pulvérulente photo-conductrice utilisée comme encre régénérative, l'encre pulvérulente, qui entre en contact avec une zone imprimée sur laquelle la couche d'encre est transférée et à laquelle la couche d'isolation par rapport à la terre est exposée, devient électro-conductrice par application d'un faisceau et adhère à la couche de base en raison d'une force électro-statique qui se crée entre elle et l'électrode se trouvant sur le côté d'irradiation du faisceau. D'autre part, l'encre pulvérulente photo-conductrice qui entre en contact avec une zone non imprimée est retenue par un manchon, dès lors que l'exposition est interrompue par la couche d'encre, et n'adhère pas à la couche d'encre. Après réapprovisionnement sélectif de l'encre pulvérulente, la feuille d'encre est chauffée de façon à faire fondre puis à solidifier l'encre, et la feuille est régénérée. On peut obtenir un appareil de formation d'image entraînant un coût de fonctionnement faible en prévoyant un mécanisme de régénération répétée de la feuille d'encre.

Abstract: Un élément photosensible photoconducteur (2) et un support de retenue de charge (1), qui sont placés l'un en face de l'autre à un intervalle prédéterminé, sont exposés à une source de lumière pendant l'application d'une tension entre eux à partir d'une source de courant externe (E). La décharge qui se produit dans les régions exposées produit une image électrostatique sur le support de retenue de charge. Dans ce procédé, la tension appliquée est interrompue après un temps prédéterminé après la fermeture d'un obturateur (13), de façon à ce que toutes les porteuses générées dans l'élément photosensible puissent être transférées sur le support de retenue de charge. Ainsi, la quantité de charge correspondant à une quantité d'exposition est stockée dans le support de retenue de charge, quel que soit le type d'élément photoconducteur utilisé. Si le support de retenue de charge ou l'élément photosensible sont chargés à l'avance, une image positive peut être obtenue le cas échéant, même pendant que la source de courant externe est déconnectée. Dans une variante, l'application de tension peut être interrompue après que l'élément photosensible a été séparé de l'élément de retenue de charge sur lequel une image à charge électrostatique s'est formée. Dans ce cas, on empêche la distorsion de l'image. Par ailleurs, si une pièce d'espacement destinée à maintenir à distance l'élément photosensible et l'élément de retenue de charge est formée solidaire soit avec l'élement photosensible soit avec le support de retenue de charge, l'interstice de décharge peut facilement être maintenu constant. En outre, si l'électrode de l'élément photosensible ou celle du support de retenue de charge au niveau de la partie de la pièce d'espacement est retirée, cet espace a pour effet d'empêcher les ruptures diélectriques qui pourraient se produire à travers la pièce d'espacement.

The engine is provided with an ignition system (3) where the ignition point is situated after the top dead center (TDC), especially in the range of from approxmiately 0 DEG  TDC to approximately 20 DEG  TDC, preferably approximately 4 DEG  TDC. As a result, it is possible to achieve an ignition of a fuel, the spontaneous ignition capacity of which at the predetermined compression ratio does not usually suffize. The resulting ignition generates a maximum pressure in the cylinder of approximately 90 DEG  TDC, whereby a high efficiency of the fuel is obtained without simultaneously involving a steep increase in the temperature in the combustion chamber. A Venturi (71) for the combustion engine (1) according to the invention is substantially axially symmetrical when seen in the flow direction. The Venturi comprises a mixing chamber, an inlet side of an annular, slot-forming ring, an outlet side of the annular, slot-forming ring and a transition portion (77) to the inlet manifold (11).

Abstract: Un dispositif de commande numérique de moteur (10) utilise un processeur de signaux numérique (70) pour émettre des instructions de commutation qui entraînent et freinent un moteur (14). Les instructions de commutation utilisent des impulsions modulées en largeur. Pour éviter des conditions de court-circuit, le processeur de signaux numérique (70) règle automatiquement les largeurs des impulsions en fonction de la quantité de courant utilisée par le moteur (14). On mesure la vitesse du moteur en divisant la différence entre des échantillons consécutifs obtenus à partir d'un détecteur de position par le temps d'échantillonnage. Le processeur de signaux numérique (70) referme aussi des boucles de position, de vitesse et de courant. Les commandes fournies par chaque boucle sont comprises entre des limites supérieure et inférieure. De plus, le processeur de signaux numérique (70) règle automatiquement les limites supérieure et inférieure afin de compenser les modifications apportées aux caractéristiques de conception en raison des variations de température. Le dispositif de commande numérique de moteur (10) peut être utilisé pour commander différents moteurs (14) présentant différentes caractéristiques de conception simplement au moyen de la reprogrammation des limites supérieure et inférieure. Plusieurs dispositifs de commande numériques de moteur (10) peuvent être utilisés pour commander des moteurs (14) fonctionnant en tandem.
