Abstract: Polysulfone and polyethersulfone oligomers made by the condensation of phenols and halogenated moieties exhibit improved solvent resistance when capped with crosslinkable end cap imidophenols. Composites made with a blend of the oligomers and corresponding polymers formed from the phenols and halogenated moieties, but without end caps, exhibit superior impact resistance while retaining the desired solvent resistance.

Abstract: Pressure infusion apparatuses should have a high degree of long-term accuracy in respect of the delivery rate. For this purpose, the flow velocity is determined in a fluid line (13) between two sensors (17 and 18), and the delivery rate is calculated from this. A marking facility (16) marks the fluid before the sensors (17 and 18) by selective heating or injection of foreign substances. The delivery rate determined from the flow velocity is compared to a desired delivery rate, and the difference controls the pump (14) in such a way that the delivery rate thereof corresponds to the desired delivery rate. <IMAGE>

Abstract: The method for fabricating exactly aligned apertures for use in electron and ion microscopy involves the placing of a very sharply pointed tip (1) in front of a set of extremely thin metal foils (3, 5) having closely controlled mutual distances in an atmosphere of heavy gas atoms. The application of an elevated voltage at the tip (1) will result in a sputtering operation to commence and erode the metal foils (3, 5) at a location underneath the facing tip (1). The sputtering operation is continued until the first ions are detected to emerge on the far side of the lens structure (2).

Abstract: The present invention concerns an apparatus for guiding a beam of laser light into one or more optical fibres. In case the beam of laser light is guided into a single optical fibre a system of lenses and a single coupling lense is used, wherein the waist of the beam emerging from the source of laser light is depicted onto the entrance sur­face of the optical fibre. This causes the diameter of the laser beam at the entrance surface of the fibre to be con­stant, despite possible changes of divergence of the laser beam. According to a second embodiment the laser beam is al­ternately guided into a number of fibres. Hereto a rotatable mirror is located behind the system of lenses. Each fibre comprises a single coupling lens. The optical properties of the system of lenses and of the coupling lenses is such that the waist of the laser beam is again depicted onto the en­trance surface of the optical fibre. Consequently inaccura­cies of the angular mirror position are compensated by the optical system and the coupling lenses.

Abstract: A flexible strand stacker includes a conveyor having an elongated endwise travelling stretch onto which the strand is fed to be carried endwise on the stretch, a gripper to grip a trailing portion of the strand as forward extent of the strand is carried endwise on the stretch, structure to effect displacement of the gripper to a position locating the gripped portion of the strand sufficiently out of alignment with the stretch that the strand is progressively pulled sidewardly off the stretch in response to endwise travel of the stretch relative to the strand, and a holder such as a roller for temporarily and locally holding the trailing portion of the strand to the travelling conveyor means stretch to travel therewith, the holder then releases the wire strand and the gripper initially grips the trailing portion of the strand. Typically, the holder and the conveyor cooperate to effect transport of a selected length of wire on and along the trailing conveyor, so that the wire becomes positioned for gripping by the gripper.

Abstract: Procédé et système permettant la transmission d'informations entre les constituants d'un véhicule (VE) dans un véhicule. Les constituants du véhicule sont connectés à une pluralité de noeuds de transmission (NT1), NT2...NT7), qui à leur tour sont reliés à un bus (B1). Les noeuds de transmission transmetttent dans le bus des informations sous la forme de paramètres de fonctions et d'identificateurs de fonctions. Les paramètres de fonctions sont dérivés par le noeud de transmission respectif, à partir d'informations provenant des constituants connectés du véhicule. Les informations fournies à un constituant d'un véhicule sont dérivées par le noeud de transmission auquel est relié le constituant du véhicule. La dérivation se déroule à l'aide des relations fonctionnelles stockées dans le noeud de transmission respectif et des paramètres de fonctions reçus dans le bus. D'abord, certains paramètres de fonctions dont les valeurs ont changé depuis leur dernière transmission dans le bus, sont envoyés dans celui-ci à partir du noeud de transmission respectif. Certains paramètres de transmission dont les valeurs n'ont pas changé depuis leur dernière transmission à partir du noeud de transmission respectif, ne sont transférés que si aucune des valeurs des paramètres dérivées dans le noeud de transmission pour ce paramètre de fonctions, n'a été changé depuis leur dernière transmission.

Abstract: Process for the purification of waste water (effluent) with a high content of ammonium ions and containing phosphate ions by precipitation of magnesium ammonium phosphate. In a standardisation stage, the ammonium ion content of the waste water is determined and, depending on the magnitude of the ammonium ion content of the waste water, phosphate ions are added if necessary. A slurry of magnesium oxide and/or magnesium ions in excess is added in a mixing stage and the pH is adjusted to the alkaline region. Between the standardisation stage and the mixing stage a pre-treatment of the standardised water is carried out for a residence time of 5 to 30 minutes, during which the ph is adjusted to the acid region. Subsequently, in the mixing stage, the pH is slowly raised to an almost neutral level until an initial turbidity develops. Magnesium ammonium phosphate precipitates out when the pH is increased further. Discharge water materially free from ammonium ions is drawn off.
