Abstract: The invention relates to a method for cultivating cells of the most diverse type, particularly human or animal cells. According to the invention, a culture is prepared from cells of at least one specified type in a defined environment, and the cells of the relevant culture are supplied with assigned, liquid nutrient media, growth factors, gases and the like.

Abstract: The invention relates to a device (30) for culturing cells of the most diverse type, particularly human or animal cells. According to the invention, a culture is prepared from cells of at least one specified type in a defined environment, and the cells of the relevant culture are supplied with assigned, liquid nutrient media, growth factors, gases and the like. Cell culturing and incubating equipment is provided that is configured for enabling, in at least one cell culture chamber (20) of the device (30), the culturing of cells that adapt themselves in an almost optimal manner to their living and growth conditions required in individual circumstances.

Abstract: A cell culture chamber (20) for a closed cell culture system serving to continuously supply different cells with liquid nutrient media, growth factors, gases or the like essentially consists of a membrane plate (1) with a membrane (2) for accommodating at least one cell culture and with a number of channels (4, 4?, 4?, 4??) for supplying liquid, gassing and connecting sensors, of a transparent glass pane (3), which is placed on one side of the membrane plate (1) while provided for observing the inside of the cell culture chamber (20) from this side, and consists of a connecting plate (5), which is placed on the opposite side of the membrane plate (1) and which is provided with an incorporated, transparent glass pane (6) for illuminating the inside of the cell culture chamber (20) from this opposite side with the aid of an assigned lighting system.

Abstract: There is indicated a web of bags comprising a carrying strip (20), on which individual bags (22) are fastened through discrete suspension sections (24). In the suspension sections (24), there are provided in the end that is to the rear in the direction of delivery during packaging notches (30) which extend to the edge of the suspension sections (24) and which facilitate the blowing-open of the bags (22) in an air curtain that is disposed substantially in the bag plane and is directed towards the filling aperture of the bag. For the very first lifting of the bag front wall, there may be provided in the bag rear wall, at the level of the end of the front wall of the bag, additional holes (18) through which a jet that is vertical on the bag plane can be directed towards the front wall of the bags.

Abstract: A windshield wiper system comprises a wiper blade having two wiper lips extending in spaced parallel relationship. The wiper lips are interconnected at the ends thereof by further wiper lip portions to define a continuous seal cooperating with the surface of the windshield to be cleaned to define an essentially closed cavity. The latter communicates with cleaning liquid supply means adapted to completely fill said cavity and establish a positive pressure therein. An ultrasonic transducer assembly is acoustically coupled to the surface of the windshield by the mass of water contained in the cavity. By moving the wiper blade together with the ultrasonic transducer assembly across the windshield the dirt clinging to the surface of the windshield becomes detached and suspended in the cleaning liquid. Thus the dirt is most effectively removed.
