Abstract: The present invention relates to a connector system for use in connecting conduits together, such as those used with an extracorporeal blood circulation system. The system has a male and female connector and a seal. The seal is operatively associated with the male and female connectors and forms a fluid tight connection between the male and female connectors. An inner surface of the seal and the inner surfaces of the first and second coupling ends form a continuous and smooth transitional surface.

Abstract: An extracorporeal blood treatment system including a gas exchange module operatively associated with a gas supply unit and optional pump for removing CO2 from blood. The gas exchange module includes a plurality of short conduits that are uniquely configured and arranged in a gas exchange mat to for efficient CO2 diffusion under conditions of low blood flow.

Abstract: In a device for handling blood in extracorporeal blood circulation that has at least one oxygenator, one heat exchanger, and one blood filter, the inlets and outlets in the oxygenator/heat exchanger unit are embodied such that a blood flow cross section of A?80 mm2, preferably A?120 mm2, is assured. The device can also be operated in an isolated form as a single structural part, which takes on the functions of an oxygenator and a heat exchanger with a blood filter. If a pump is provided in the device, then the pump drive can be removed as needed.

Abstract: The invention relates to a method of establishing and optimizing, in a perfusion system with two independently regulatable pumps, at least two independently regulatable circulations which are interconnected via at least two junction points and contain substantially the same fluid, in particular blood, blood plasma or electrolyte solutions. The perfusion system may comprise any standard devices such as those for pumping, transfer, flow or pressure regulation, filtration, bubble elimination, substance and energy exchange, or measurement of physical/chemical parameters of the fluid.

Abstract: In a venous bubble trap (1), having a housing (2) to which fluid, in particular blood, can be delivered essentially tangentially via a fluid inlet (8) and from which fluid can be carried away via a fluid outlet (10), and having a filter device (3) located in the interior of the housing (2), the filter device (3) divides the housing interior into a prefilter region (5) and a postfilter region (6), and the postfilter region (6) surrounds the prefilter region (5) in at least some portions. As a result, air is reliably removed from the fluid.

Abstract: Processes for producing semiconductor components and/or other finely structured components include providing a projection objective having a mirror that is located within a predetermined proximity to a pupil surface of a projection objective. In one variant, an image of a pattern is projected onto a light-sensitive substrate in multiple exposures, in which a first pupil filter function is set on the mirror during a first exposure and, during a subsequent, second exposure, a different, second pupil filter function is set by local changes of geometric reflective properties of the mirror in a locally resolving manner.

Abstract: A catadioptric lens with optical elements, which are arranged along an optical axis and with at least one concave mirror located in the vicinity of a pupillar surface of the projection lens. The concave mirror is sub-divided into a number of annular or honeycomb mirror segments, which can be displaced independently in relation to one another with the aid of piezoelectric drive elements. The mirror can be used as a phase-shifting pupillar filter, whereby the filtration function can be adjusted by the relative displacement of the mirror elements in relation to one another.

Abstract: The invention relates to a device for forming a peripherally closed hollow profiled element (1) by means of fluidic internal high pressure. The device contains an axial plug (4) for sealing off the hollow profiled element (1) on the end face, said axial plug possessing an axial passage duct (5) supplying pressure fluid. The axial plug (4) has a sealing body which possesses on its end face (19) a trough-like depression (20), the peripheral wall (21) of which can be spread open radially elastically, within the hollow profiled element (1), by means of pressure fluid, until said wall comes to bear sealingly against the inner wall (22) of the hollow profiled element (1).

Abstract: In a method and a device for joining a plane component to a hollow section, the component and the hollow section are inserted in an internal high pressure forming tool so as to be positioned in relation to each other and are connected through the subsequent aid of a fluidic high internal pressure in the hollow section. In order to achieve a connection between the plane component and the hollow section in a simple and process-controlled manner, while the high internal pressure is applied, the walls of the hollow section and the component, which rest against and are supposed to be connected with each other, are pressurized by a die that is integrated in the forming tool. The wall of the hollow section is punched so that the created slug is attached in a positive bonding manner to one area of the hole edge and increase in terms of its width towards its free end.
