Abstract: Coulisse de puits (11) possedant un corps allonge (14) avec un passage axial et des connexions filetees (12) (13) permettant l'assemblage en une chaine de conduite de puits. Le corps possede un mandrin (16) tubulaire monte de maniere coulissante a l'interieur cylindre (17), la partie annulaire (18) entre ces deux elements etant exposee au fluide du puits. Des joints etanches au fluide dans la partie annulaire permettent d'obtenir une chambre isolee (22) contenant un verrou au moyen duquel le mandrin et le cylindre sont relaches de maniere selective pour appliquer une force d'impact a la conduite du puits. L'amelioration apportee a la coulisse comprend une pluralite d'amortisseurs par friction (77) allonges a vibration elastique solidaires du mandrin et alignes longitudinalement dans l'espace annulaire (18) entre le mandrin et le cylindre. Les amortisseurs engagent de maniere coulissante le cylindre d'un bout a l'autre de son mouvement telescopique le long du mandrin Les amortisseurs sont ecartes a la circonference autour du mandrin et les espaces ainsi crees forment des canaux d'ecoulement dans l'espace annulaire permettant l'ecoulement du fluide du puits lorsque la coulisse est montee dans la chaine de conduite de puits en rotation dans le forage du puits.

Abstract: Die Erfindung befaßt sich mit der Vibrationsbeseitigung bei einer Zuführkette oder einem Förderer 12 von Maschinen zum Sammeln von bedruckten Bögen. Die Hin- und Herbewegung in einigen Bestandteilen des Systems schafft ständig wiederkehrende Kräfte, die bei oder in der Nähe der Eigenschwingungszahl der Zuführkette 12 liegen können. Dies verursacht unerwünschte Schwingungen in der Kette. Die Erfindung dämpft diese Schwingungen durch ein ständiges Einschränken im Bereich des unteren Laufes der Kette 12 sowie durch die Anordnung eines positiven Antriebs 92 an dem Endteil der Kette 12, um etwas von dem Spiel beim Rücklauf aufzunehmen. Die Vibration wird auch reduziert an ihrer Quelle durch das Anordnen eines Schwungrades 40 auf der Antriebsachse 36 in der Nähe des Punktes, wo die Hin- und Herbewegung entsteht.

Abstract: An optical information processor in which predetermined information is recorded by a first laser light beam (1) on a recording medium (103) along a guiding groove (4) previously formed in the recording medium. Second and third laser light beams (2, 3) are projected onto the recording medium at positions deviated from the center of the guiding groove and preceding and succeeding to the first laser beam (1). A pattern (D) in which no mutual interference of information to be recorded by the first laser beam is present is detected from information signal which modulates intensity of the first laser light beam. Difference is determined between the quantity of light reflected upon illumination of the recorded pattern by the second laser beam (2) chronographically succeeding to the first laser beam and the quantity of light reflected upon illumination by the third laser beam (3). The position of the first laser beam (1) is controlled on the basis of the thus determined difference for effecting information tracking operation with improved accuracy.

Abstract: In producing an edited tape (31) the lead-in material up to a first edit point is separated from the lead-out material running from a second edit point by a space containing unwanted material and accommodating the actual or notional splice. The unwanted material ensures correct operation of error protection for all of the wanted material on replay. The first and second edit points are marked by codes placed on the tape (31) by a code processor (43) and supplementary head (42). During replay the digital data recovered from the tape by a head (32) is entered into a random access buffer store (34) under control of a write address generator (38) and read out to output electronics (37) under control of a read address generator (39) running at the audio sampling rate. The write address generator (38) normally runs at a rate corresponding to tape speed but the code processor detects the codes for first and second edit points and a control unit (51) stops the write address generator (38) between such points so as to discard the unwanted material. The store is then replenished by speeding up the tape by a comparator (40) and speed control unit (10) in an arrangement which preserves a constant relationship between the read and write addresses, i.e. a constant degree of filling of the memory (34).
