Abstract: A liquid-transport device has a liquid-tight support (12) on which there is applied a start zone (24; 24?) for applying transport liquid to be transported and a target zone (26, 28; 26a-e) into which the transport liquid is to be transported and also a conduction zone that extends between the start zone (24, 24?) and the target zone (26, 28; 26a-e) and that has a microporous transport layer (14) in which the transport liquid flows by capillary force from the start zone (24; 24?) to the target zone (26, 28; 26a-e). The conduction zone has a multiplicity of open flow channels separated from one another by microporous bridges having open-pored side walls.

Abstract: There is disclosed a cellulosic microporous filtration membrane with upper and lower porous protective layers with a porous sponge-type intermediate layer between the two protective layers, wherein the sponge-type structure consists of two isotropic regions having different pore sizes.

Abstract: Measurements are performed for detecting a mass calling to a subscriber (T) in a telecommunications network (KN), for controlling the establishment of connections to the subscriber (T) who is the destination of the mass calling. If a connection is blocked as a busy connection due to a detected mass calling, information announcing the establishment of the busy connection to the involved exchanges (B3, B, M, M2 and BM22) is added to a back-signalling message to release the connection which is busy because of the mass calling.

Abstract: It is proposed that in a telecommunications network (KN) for control of mass callings to subscribers of the telecommunications network (KN) with exchanges (VST1, . . . , VST7), each of which has a control means (SM1), to perform measurements to detect a mass calling to a subscriber exclusively in those exchanges (VST1, . . . , VST5) of the telecommunications network (KN) to which a subscriber, who is the possible target of such a mass calling, is connected. The exchange (VST1) which detects the mass calling signals its occurrence to respective predetermined further exchanges (VST2, . . . , VST5, VST7) in the telecommunications network (KN). Each of the predetermined further exchanges (VST2, . . . , VST5, VST7) and the exchange (VST1) which detects the mass calling, chokes the traffic to this subscriber at a rate that is fixed for the respective predetermined further exchange.
