Abstract: The excavator tooth has a tooth holder (1) on one end of which a wedge-shaped tooth nose (3) is developed. The tooth nose (3) bears a wedge-shaped tooth cap (5) in which a wedge-shaped hollow space (24) is recessed. With the tooth cap (5) mounted, the hollow space (24) is pushed over the tooth nose (3), which thus supports the tooth cap (5). For a good support, the wedge surfaces (8, 9) of the tooth nose (3) have radii of curvature curved convexly perpendicular to the longitudinal axis (16) and continuously decreasing from the tooth edge (7) to the nose root (17). In corresponding manner, the wedge surfaces (25, 26) of the hollow space (24) have concavely curved radii of curvature which continuously decrease from the base (28) to the mouth (29) of the hollow space (24). In this way a large application surface of the tooth cap (5) on the tooth nose (3) is obtained.      In order to secure the tooth flap (sic) (5), a locking pin is provided which passes through the holes (20, 34) in the tooth nose (3) and the side surfaces of the tooth cap (5) and holds the latter fast.

Title: Optical seeking method and apparatus
Inventor: LEWIS DAVID EARL
IPC: G11B7/085
Filed: 1996-02-26
Granted: 2007-05-01
Abstract: There is disclosed a method for moving an optical head from an initial track (10) to a target track (11) on a storage medium (1). The total number of tracks (3) to be crossed is determined, and the optical head is moved toward the target track (11). A reflectivity level of light from the storage medium (1) is measured, and a tracking error signal is derived from the reflectivity level. The tracking error signal has both true and false indicators of track crossings. A data indicator signal is derived from the reflectivity level, having indicator points corresponding to the false indicators of track crossings. A track count number is incremented for each true indicator of a track crossing, and the optical head is stopped when the track count number equals the total number of tracks (3) to be crossed. Another method is disclosed whereby a track count signal is generated from the tracking error signal and the data indicator signal. The track count signal indicates track crossings corresponding to the true track crossing indicators in the tracking error signal. An apparatus is disclosed comprising a sensor (14) for measuring the reflectivity level from a storage medium (1), a tracking error signal generator (17) for generating a tracking error signal, a preamplifier (15) for generating a data signal, a track crossing signal generator (18) responsive to the tracking error signal, and a track/hold selector (16) responsive to the data signal to direct the track crossing signal generator (18) to generate a track crossing signal without the false track crossing indicators from the tracking error signal. A second apparatus is disclosed comprising a sensor (14) for measuring the reflectivity level from a storage medium (1), a preamplifier (15) for generating a data signal, a tracking error signal generator (32) responsive to the reflectivity level for deriving a tracking error signal, a track/hold selector (31) to direct the tracking error signal generator (32) to generate a signal of constant amplitude (43) for a predetermined period of time based on the data signal, and a track crossing signal generator (33) responsive to the tracking error signal for deriving a track crossing signal indicating the crossing of an information track by the optical head.

Abstract: Dans un réseau de commutation à large bande, destiné à la commutation de cellules de données à transfert asynchrone, un contrôleur dynamique de largeur de bande gère l'application des cellules de données à un port d'entrée du système, ces cellules étant fournies par plusieurs systèmes émetteurs terminaux. Ce contrôleur offre un tampon aux cellules venant des différentes sources et commande la sortie des cellules de données vers le système en fonction d'un débit ponctuel de cellules attribué aux cellules provenant du système terminal respectif. Lorsqu'un système terminal commence à émettre des cellules de données, le contrôleur détecte la présence de ces cellules arrivantes et demande une largeur de bande à une commande d'admission de connexions faisant partie du système, tout en fournissant un débit de cellules par défaut au système terminal pour que la transmission puisse continuer en attendant l'attribution de la largeur de bande appropriée. Le contrôleur comprend un tampon permettant de stocker des cellules lors d'une telle situation. Une fois attribuée la largeur de bande appropriée, les informations, contenant des avis de débit de cellules venant de la comamnde d'admission de connexions, repartent vers le contrôleur et de là vers le système émetteur terminal pour empêcher la transmission de cellules à un débit trop élevé pour la largeur de bande disponible. L'invention concerne à la fois un appareil et un procédé.
