Abstract: Systeme de prevention de collisions de transmissions pour un systeme a reseau de distribution pour le traitement de donnees comprenant un tableau de communication semi-duplex couple a un systeme bus (3). En plus d'un bus de donnees en serie (120) et d'un bus horloge (121), le systeme bus comprend une ligne d'etat d'occupation (122) qui est controlee par chaque dispositif connecte au systeme. Lorsqu'un dispositif desire transmettre un message, il procede initialement a la liberation de la ligne d'etat d'occupation, en placant un indicateur d'occupation (97) sur la ligne. Il verifie egalement la ligne d'etat d'occupation (83) afin de se rendre compte si un indicateur d'occupation a deja ete pose notamment, si un autre dispositif a deja reclame le service. Si le bus est occupe, le dispositif ne peut pas transmettre jusqu'a ce que le bus devienne libre et le dispositif demandeur replace l'indicateur d'occupation du bus pour un nouvel interval d'essai. En supposant que le bus est libre, le dispositif transmetteur (22) se met a transmettre. Lorsque le dispositif, pour lequel le message est destine, recoit le message, il renvoie un message d'accuse de reception au dispositif transmetteur, en signe de transmission reussie. A cause des temporisations dues au fonctionnement et a la propagation dans les circuits, il se peut que plus d'un dispositif mette en place un indicateur d'occupation et verifie l'etat du bus sans savoir qu'un autre dispositif demande simultanement l'utilisation du bus. Dans ce cas, une collision de transmission se produira, et les recepteurs, ne recevant pas une transmission comprehensible ne renverront pas de messages d'accuse de reception aux transmetteurs ayant participe a la collision. Lorsqu'un transmetteur n'arrive pas a recevoir en retour un message d'accuse de reception, il suppose qu'une collision s'est produite et procede a la repetition de la procedure ci-dessus pour transmettre a nouveau le message en suivant un schema de priorite prescrit, le dispositif a haute priorite etant assure de

Abstract: Poröse Hohlfasermembranen für die Plasmaseparation werden hergestellt durch Extrudieren eines speziellen homogenen Gemisches aus einem schmelzbaren Polymeren und einer inerten Flüssigkeit in ein Spinnrohr, das die inerte Flüssigkeit des extrudierten Komponentengemisches enthält, wobei die Flüssigkeit im Spinnrohr eine Temperatur unter der Entmischungstemperatur besitzt. Die entstehende Faser wird unter geringer Spannung aus dem Spinnrohr abgezogen und nach ihrer Verfestigung mit einem Lösungsmittel ausgewaschen. Die Hohlfasermembranen weisen einen Siebfaktor für Humanblutproteine im Molekulargewichtsbereich von etwa 60.000 bis 3 Millionen von mindestens 0,7, vorzugsweise von 0,9 bis 1,0 auf. Sie zeichnen sich unter anderem durch einen Filtratfluß von mindestens 1/5 des Blutflusses durch den Filtermodul aus, wobei der Filtratfluß bei einer Druckdifferenz von 0,1 bar bestimmt wird. Als Polymere eignen sich insbesondere Polyolefine, vorzugsweise Polypropylen. Der Porenhohlraumanteil der Membranen betragt mindestens 70 %. Bei der Herstellung der Hohlfasern wird die inerte Flüssigkeit mit etwa gleicher oder nur geringfügig unterschiedlicher linearer Geschwindigkeit durch das Spinnrohr geführt wie die Faser.

Abstract: A mechanical spectral shift reactor for controlling a nuclear reactor with a plurality of reactor coolant displacer members (40) which are inserted into a reactor core (34) at the beginning of the core life. The displacer members reduce the volume of reactor coolant-moderator in the core (34) at start-up. However, as the reactivity of the core (34) declines with fuel depletion, selected displacer members (40) are withdrawn from the core (34) at selected time intervals. The withdrawal of the displacer member allows reactor coolant to enter the core (34) which increases core moderation at a time when fuel reactivity is declining. Thus for a given amount of nuclear fuel the life of the core can be extended or for a given life of a core the uranium fuel requirements can be reduced.

Abstract: A catheter device (1) is disclosed which is intended either to work as a catheter per se or to work as a catheter adapter to be connected to a conventional catheter. The device is of that type which comprises a channel (5) intended for the liquid to be drained from a body cavity (2), and a channel forthe inletof gas, usually air, into the liquid channel (5) to break a liquid column in the liquid channel. An especially preferable use of the device according to the invention is for the drainage of a urinary bladder, 
     Previously known devices for the inlet of air have been provided with some form of a bacterium filter. According to the invention the need of a bacterium filter is completely eliminated. This is achieved by the fact thatthe gas channel (6) comprises two openings, the first one of which opens into a liquid collecting means (4) and the second one of which (9) opens into the liquid channel (5) upstream the outlet of the liquid channel into the liquid collecting means. Through the fact that the rest of the gas channel (6) is closed from the surrounding a totally closed gas circuit is obtained, wherein the gas intended for entrance into the liquid channel (5) is taken from the liquid collecting means (4). Thus, there will be no need of any gas from the outside. 
     According to a preferable embodiment of the device the gas channel (6) is dimensioned more narrow than the liquid , channel (5).
