Abstract: L'unité à laser dentaire possède un logement (12) ayant des première et seconde cavités à laser. Le logement comprend également un orifice de sortie optique (18) et un système d'apport optique dentaire (100) qui est connecté optiquement à l'orifice. Un premier laser (14) est contenu dans la première cavité à laser qui, lorsqu'elle est activée, génère un premier rayon laser, et un second laser (16) est contenu dans une seconde cavité à laser laquelle, lorsqu'elle est activée, génère un second rayon laser. Cependant, seul un laser est activé à un moment donné et le rayon de sortie provenant de la cavité à laser activé est dirigé sur l'orifice de sortie optique dans le logement pour des applications dentaires. Le premier laser possède des qualités optiques suffisantes pour effectuer un premier ensemble d'opérations dentaires, tandis que le second laser possède des qualités optiques appropriées pour effectuer un second ensemble différent d'opérations dentaires.

Abstract: The invention relates to an auxiliary device for a loom (100), which loom comprises essentially an integrated leno device (300, 300') for producing a fabric weave and an appropriately assigned treadle device (75) which are in engagement, via a plurality of linkages (80') of a linkage system (80), with appropriately assigned heald frames (90') for shed formation with subsequent weft insertion. In the proposed auxiliary device (60, 160, 260), two linkages (80') connected operatively to the associated heald frames (90') are uncoupled from the treadle device (75), the uncoupled linkages (80') in each case being connected operatively to an eccentric element arranged on a second shaft (18) driven by a first shaft (78), in such a way that, when the eccentric elements are actuated, an actuation of the heald frames (90') corresponding to the eccentric elements which is coordinated in time with the functioning of the leno device (300, 300') and which is independent of the treadle device (75) can be achieved. The auxiliary device (60, 160, 260) ensures, for example during the weft insertion into the upper and lower sheds formed, that, during the phase in which the shed remains open, a shed closing independent of the actual shed takes place and, at the same time, each weft yarn is turned individually into the leno weave and consequently a stabilisation of the selvedges is achieved. <IMAGE>

Abstract: The brake cylinder is made from an extruded section by a procedure in which the required piece of section is cut to length and closed at the end with a cap (19). The section comprises a cylinder shell (11) with connection strips (13, 14, 15) projecting from it. A flange part (22) is fixed on the cylinder shell (11). The holes (26) for the tank ports and holes (27) for the pressure connections are drilled into the connection strips (13, 14, 15) radially to the cylinder shell (11). Because it is produced by extrusion, the inner surface (12) of the cylinder shell has a surface finish which is of such high quality that aftertreatment is not necessary. <IMAGE>

Abstract: Un appareil et un procédé d'enregistrement sans impact du niveau de gris transmettent des signaux à une tête d'enregistrement à N éléments d'enregistrement par pouce, de façon à permettre l'enregistrement de M sous-lignes par pouce, où M est plus grand que N. Si l'on prend l'exemple d'une tête d'impression à diodes électroluminescentes de 400 dpi, les données du niveau de gris sont envoyées à la tête d'impression à une cadence permettant d'enregistrer par exemple 2400 lignes par pouce, ce qui donne une résolution de 400 dpi x 2400 dpi sous-pixels de niveau de gris. Les données provenant d'une source de données peuvent avoir une résolution de pixels de 1/400" x 1/400", et l'appareil emploie six sous-lignes pour enregistrer chacun de ces pixels. Le système de contrôle de la durée d'enregistrement de chaque diode électroluminescente pour chaque sous-ligne comprend un circuit comparateur qui reçoit les signaux de données du niveau de gris à un terminal d'entrée ainsi que des impulsions représentant un comptage de changement de cadence à un autre terminal. Le comptage est réalisé par compteur et est modifié en fonction de signaux provenant d'une horloge. Une commande précise de l'exposition, surtout au pied de la courbe d'exposition est réalisée grâce à un schéma de chronométrage à vernier, le compteur étant commandé par des horloges mères alternantes pendant l'enregistrement de sous-lignes alternantes. Les horloges mères génèrent des impulsions d'horloge à des fréquences légèrement différentes, ce qui a pour résultat de modifier la synchronisation des impulsions provenant des compteurs. Dans une réalisation l'horloge peut être une horloge non linéaire programmable qui donne une plus grande plage d'enregistrement du niveau de gris.

Abstract: A spring applied - hydraulically released (SAHR) type wet disc brake for a wheeled vehicle having a large braking torque and energy absorption capacity. The brake unit includes a piston housing in which an annular piston is mounted for reciprocal movement towards and away from a disc housing. The disc housing defines a disc chamber in which a plurality of interleaved non-rotating and rotating discs are disposed. A pressure plate disposed on one side of the disc pack is mounted for reciprocating movement towards and away from the disc pack and is operative to apply clamping forces to the discs in order to generate braking torque. A plurality of biasing springs urges the pressure plate towards engagement with the disc pack. Pressurized fluid applied to the piston maintains the pressure plate in a released position. Selective reduction of pressure to the piston effects braking action. A piston-to-reaction plate seal inhibits coolant flow between an inner face of the pressure plate and the adjacent disc. A pressure plate seal carried by a periphery of the pressure plate sealingly engages the disc housing and inhibits coolant flow from the disc chamber, across the pressure plate. A coolant inlet distributes coolant throughout the periphery of the disc chamber. Coolant then flows between the interleaved rotating and non-rotating discs toward a central region from where it is exhausted through one of the spring chambers. Aligned locations defined by teeth removed from the rotating discs together with a wheel hub member form coolant passages. The pressure plate includes a plurality of standoffs that extend across the disc pack and are engageable by the piston located on the opposite side of the disc pack. The piston applies forces which oppose the spring applied forces.

Abstract: A circuit arrangement for contactless controlling of a sanitary fitting comprises a transmitter (1) which, controlled by a clock generator (5), emits radiation pulses with the clock frequency of the latter. The radiation reflected by an object (2) in a monitoring area passes to a receiver (3). The output signals of the receiver (3) are counted in a logic control circuit (9). If the number Nz determined during this counting over a certain number N of clock pulses of the clock generator (5) exceeds a number N1 stored in a first memory (10), the logic control circuit (9) generates at an output (A) a signal which opens the solenoid valve (4) of the sanitary fitting. If after generating an output signal at the output A of the logic control circuit during the counting of the output pulses of the receiver (3) over N clock pulses a number Nz is established which is less than a number N2 stored in a second memory (11), the logic control circuit (9) provides at a second output (B) an output signal which re-closes the solenoid valve (4). <IMAGE>
