Abstract: FIELD: rocket technology. 
     SUBSTANCE: carbon fibreglass (CFG) insert with adjustable planned erosion resistance can be used in the nozzle unit of a solid-propellant rocket engine. The composition of the pressed plate of a CFG insert consists of consecutively alternating fractions of layers of silica and carbon fabrics or layers of fabric woven from fractions of carbon and silica threads impregnated with a grade A polymer binder FN, and by changing the ratio of fractions of carbon and silica fabrics or fractions of carbon and silica threads in the fabric woven from carbon and silica threads, allows for adjustment and production of compositions of various erosion resistance under the impact of the flow of rocket fuel combustion products, perpendicular to the layers of fabrics in the range from the erosion resistance of an insert made of pressed plates of silica fabrics to the erosion resistance of an insert made of pressed plates of carbon fabrics, since an increase in the proportion of carbon threads increases the erosion resistance of the insert in the nozzle unit of the rocket engine and, accordingly, a reduction in the proportion thereof contributes to a reduction in the erosion resistance. 
     EFFECT: creation of a CFG insert suitable for use in the nozzle unit of a solid rocket engine.

Abstract: A data exchange system is connected to at least one signal converter in which digital signals emitted from teletex subscriber stations are converted so that they may be processed by teletex subscriber stations, and vice-versa. In order that the load on the signal converters may be as low as possible in the event that digital signals cannot be deposited in the desired subscriber station, the data exchange system is additionally connected to at least two special teletex transmitting/receiving devices. These teletex transmitting/receiving devices can be operated by a special call signal only in the event that a teletex subscriber station or a signal converter is currently unable to deposit digital signals in the desired subscriber station. In response to such operation of the teletex transmitting/receiving devices, the latter is supplied with digital signals which cannot currently be deposited, together with additional information which enable the establishment of a connection to the desired subscriber station. Subsequently, the teletex transmitting/receiving device is able to transmit the digital signals which it has received, on the basis of the additional information, to the desired subscriber station.

Abstract: Durch die Erfindung wird eine Schaltung für eine Lichtrufeinrichtung beschrieben, mit deren Hilfe insbesondere in Krankenhäusern dem Pflegepersonal Lichtsignale oder akustische Signale gegeben werden. Bekannte Lichtrufeinrichtungen dieser Art haben den Nachteil, daß sie zur Erfüllung der vielfältigen Funktionen drei Signaladern und eine aufwendige und große Gruppenzentrale benötigen, an der die Signaladern für die Meldungen der einzelnen Zimmer zusammenlaufen. Es ist auch eine Lichtrufeinrichtung bekannt, die mit zwei Signal adern auskommt, diese benötigt aber ebenfalls eine große Zentrale in einer Zweifachdose. Durch die Erfindung wird es möglich, mit zwei Signaladern auszukommen und extrem kleine Abmessungen für die Gruppenzentrale zu erreichen, indem durch die erfindungsgemäße Schaltung dieser nur noch die Funktion zukommt, auf der Rufnachsendungsleitung und der Rufmeldungsleitung je nach Rufzustand logische Potentiale zu schalten, was z.B. unter Verwendung eines Multiplexers mit billigen und einfachen Mitteln möglich ist. Die Rufmeldungsleitung wird bei dieser Schaltung mehrfach ausgenützt, wobei für einen automatischen Vorrang bei Notruf gesorgt ist.
