IPC: G02B6/32
Filed: 1981-03-18
Abstract: Einrichtung zur Verbindung von Lichtleitern (2) in Form von Steckern (1) oder Verteilern (11) bzw. Schaltern. Es wird eine in die Stecker (1) bzw. Schalter integrierte aufweitende Optik (3) verwendet, die in einer 1. Ausführungsform aus einer Planasphäre (3) besteht und in einer 2. Ausführungsform aus einer direkt auf den Lichtleiter aufgesetzten, konischen Konvexlinse. In beiden Fällen werden Koppelverluste infolge der Lichtreflexion an Glas-Luft-Grenzflächen bei Linsensteckern durch Verringerung der Anzahl dieser Grenzflächen minimiert. Dazu befinden sich die Linsen (3) im 1. gegenseitigen Immersionskontakt bzw. 2. im Immersionskontakt mit den Lichtleitern. Da an der Verbindungsstelle der Stecker (1) paralleler Strahlengang vorliegt, sind diese zentrierunempfindlich.

Abstract: Zum Aufbau eines sammelleitungsorientierten, nach dem Frequenzmultiplexverfahren betriebenen, optischen Kommunikationssystems werden steckbare Koppelelemente und Farbcodierer und -decodierer vorgeschlagen, die als selbstkollimierende optische Elemente ausgelegt sind. Die Koppelelemente bestehen aus einem in die Sammelleitung eingebauten selbstkollimierenden Teil (22a) und einem darauf aufsetzbaren Gegenstück (22b). Ohne Gegenstück reflektiert das Koppelelement das aus der Sammelleitung austretende Licht praktisch verlustlos wieder in die Sammelleitung zurück, beispielsweise durch Totalreflexion. Das aufgesetzte Gegenstück enthält frequenzselektive Mittel (z.B. ein Interferenzfilter 25) und koppelt, z.B. durch Störung der Totalreflexion, das gewünschte Wellenlängenband aus der Sammelleitung aus. Die Frequenzcodierer und -decodierer bestehen ebenfalls aus selbstkollimierenden Bauteilen, die entweder über Koppelelemente angeschlossen werden oder direkt in die Sammelleitung eingebaut werden können. Die Farbcodierer verwenden bevorzugt Reflexionsgitter als dispersives Element; ein Farbcodierer, der in die Sammelleitung eingebaut wird, besteht aus zwei Hälften mit ineinandergreifenden Reflexionsgittern, bei dem das reflektierte Licht frequenzmässig aufgespalten wird, das durchgehende Licht dagegen keine Aufspaltung erfährt.

Abstract: In a pulse radar apparatus target returns are detected, sampled, digitised per range quant and frequency analysed. The apparatus comprises a cell classification unit (5) for deriving from the spectrum of the target returns a cell classification signal, whose logical values indicate that the target returns within a radar cell are classified, in the first instance, to be from a moving target and from a fixed target. In a microprocessor (15) the cells, which collectively cover one single target, are combined to form a cluster, while a signal representative of the target covered by the cluster is determined. Furthermore in the microprocessor (15) a cluster classification signal is derived, whose logical values indicate that the target returns within the cluster are classified to be from a moving target and from a fixed target. The signal representative of the target covered by the cluster is read out if it is derived from target returns classified to be from moving targets.

     2,6-Di(alkylamino) derivatives of chloronitropyrazines are prepared from dichloronitropyrazinamine by diazotization of the amine followed by halogen exchange to produce an intermediate dichloro-halo nitropyrazine followed by reaction with one or two motes of an alkyl amine to effect replacement of one or two of the pyrazine halogens. 
     N-acyl derivatives of 6-lalkylamino)-5-chloro-3-nitro- pyrazinamines are prepared by treatment of 5,6-dichloro-3-nitropyrazinamine with an acylating agent to produce the corresponding acylated pyrazinamine followed by treatment of said acylate dpyrazinamine with a lower alkylamine to replace one of the chloro substituents and produce a 2-acylamino-6-(alkylamino)-5-chloro-3-nitro pyrazinamine.

L'extremite opposee de la tige indicatrice. portant des marques de graduation (18), s'etend axialement vers l'exterieur de la tige d'actionnement. La rotation de la tige d'actionnement provoque le mouvement du piston axialement par rapport au corps cylindrique lorsque le collier est engage, et au fur et a mesure que la pression du fluide dans le corps cylindrique augmente, le ressort se comprime et par consequent la tige indicatrice s'etend davantage vers l'exterieur a partir de la tige d'actionnement et indique la pression du fluide.
