Abstract: A packaging container made of a plastic film. The packaging container includes a receptacle space for goods arranged between a front wall and a rear wall, an upper and a lower traverse seam which closes the packaging container on an upper and a lower end, respectively, connecting seams running between the upper and lower traverse seams, a film strip fastened to an internal side of the front wall via the connecting seams, a longitudinal channel formed by the film strip, the front wall and the connecting seams, and an engagement element arranged in the longitudinal channel. The engagement element is arranged transversely to a longitudinal extent of the longitudinal channel, and in a cross section above the film strip, to permit an engagement in the longitudinal extent of the longitudinal channel between the front wall and the film strip. The engagement element forms a handle with the front wall.

Abstract: The invention relates to a bag (3) having a filling space for bulk material, which filling space is delimited by a lower base (4), a circumferential wall (6), and an upper filling space closure (8) facing away from the lower base (4). The bag has at least one tear-open strip (10) for exposing an opening area (12) of the bag (2), which is delimited by an upper weakening line (14) and a lower weakening line (16), wherein both weakening lines (14, 16) extent parallel to the upper filling space closure (8), and the upper weakening line (14) is positioned between the upper filling space closure (8) and the lower weakening line (16). The bag (2) has a longitudinal seam (18) extending transversely with respect to the upper filling space closure (8). The upper and the lower weakening line (14, 16) begin in the area of the longitudinal seam (18).

Abstract: A packaging container has walls made of film defining an interior of the packaging container. At least a first one of the walls has two wall parts that overlap one another forming an inwardly positioned overlapping strip and an outwardly positioned overlapping strip and providing an intermediately positioned venting passage. The overlapping strips are connected to one another by a securing seam that extends along an edge of the inwardly positioned overlapping strip. The venting passage communicates through inner openings with the interior and through outer openings with the ambient. The outwardly positioned overlapping strip has no openings. At least one filter is provided with the outer openings of the venting passage and is positioned underneath the outwardly positioned overlapping strip in a flat arrangement.

Abstract: Test device (1) is for use in a test system for checking transmission procedures in a mobile telephony network. The test device (1) comprises a mobile telephone (2) configured such that it is able to communicate with a subscriber identification module (SIM). Furthermore, the test device (1) has a SIM simulation processor (4) associated locally with the mobile telephone (2), to prepare a SIM simulation which may be connected to other components of the test system. The test device (1) also has a physical SIM card (10) connected to the SIM simulation processor (4) such that the mobile telephone (2) is able to selectively communicate with the SIM simulation or with the physical SIM card (10). A test device (1) is thus provided, the use of which allows a greater flexibility of the SIM data used in the test process.

Abstract: A culturing bag for microorganisms has a wall formed of plastic film wherein at least one wall area of the wall is permeable for oxygen and carbon dioxide. A first layer of microporous film is attached to the at least one wall area as an exterior layer so as to form a multi-layer configuration in the at least one wall area. The first layer of microporous film is sealed by a seal-tight edge seam to the wall. The microporous film is adapted to be torn open or torn off. At least one second layer of microporous film can be placed between the exterior layer and the wall.

Abstract: A test system (1) serves to check transmission processes in a mobile radio network (2). The latter comprises a central switching computer (8), a local mobile telephone (13) equipped for SIM communication, and a transmission unit (3) comprising a local transmission unit (5). Other components of the test system (1) include a local SIM simulation computer (10), which is connected to the local transmission unit (5) on one hand and to the mobile telephone (13) on the other hand, a control computer (23), which is used for controlling the testing operation, and which is connected to the mobile radio network (2), as well as an authentication computer (14), which is connected to the SIM simulation computer (10) and with which the mobile telephone (13) can be authenticated. For the authentication, a method is used that requires only two communication steps over the remote signal connection.
