Abstract: A stack arrangement having at least two stack elements, which can be stacked on each other in a stacking direction, of which at least one is formed from a transport container which has a container body having a storage receptacle which has a machine receptacle for an electrical or pneumatic hand tool machine. The stacking elements have bus interfaces for transferring data and/or energy between the stacking elements of the stack arrangement, wherein the bus interfaces form a bus connection between the stack elements when the stack elements are stacked on each other.

Abstract: Provided are embryonic stem (ES) cell-derived tissue modeling systems. In particular, systems for the de novo generation of tissue by parallel drug selection of cell types constituting the tissue of interest in one culture of differentiating ES cells is described as well as the use of such systems in transplantation and drug development.

Abstract: Method for monitoring and controlling a loading rate of a transport section with one or several individually speed-controlled consecutive partial sections (T1, T2, T3) in a filling line, including detecting a container loading over a certain region at an incoming region (E1) of the transport section; simulating a container flow in real time using the detected container loading in the incoming region of the transport section and a transport speed, the simulation including: entering the detected value for the container loading into a shift register (SR1); and synchronizing a shift register clock with the transport speed, so that the shift register content (DW0, DW1, . . . ) represents the container loading on the transport section.

Abstract: Device for spreading apart a single-file stream of upright containers, with a single-track feed conveyor, a multi-track discharge conveyor, and a transfer station, which comprises two oppositely driven belts, which form a transport channel for the containers and which can be driven at essentially the same transport velocity as the feed conveyor, where the transport channel formed by the belts is straight and releases the containers with excess velocity onto the discharge conveyor, which can be driven at a slower transport velocity than the feed conveyor.

Abstract: A device for the buffering of objects, with two parallel conveyors which can be driven in opposite directions, and with a transfer installation which can be moved by means of at least one linear guide along the conveyors, for the transfer of objects between the conveyors, where at least one linear guide is arranged with separation above a conveyor.

Abstract: The invention relates to a system for selecting differentiating embryonic or adult stem cells or embryonic germline cells in a cell-specific and development-specific manner, using a combination of resistance genes and detectable reporter genes under the common control of a cell-specific and/or development-specific promoter.

Abstract: A surface-wave-type reflective delay line includes an input/output interdigital converter, and a plurality of surface wave reflectors. The surface wave reflectors are disposed at positions corresponding to an order of magnitude of half of a particular desired transit time of a surface wave between the input/output interdigital converter and an applicable surface wave reflector and back. At least some of the surface wave reflectors are each shifted by a mathematically random value out of the positions corresponding to half the particular desired transit time.

Abstract: An SW resonator has a substrate of piezoelectric material. Two reflectors are applied onto the one substrate side. Input and output transducers are situated between the reflectors. The SW resonator is expanded to form an SW resonator having three electrical gates by arranging an additional transducer between the reflectors.

Abstract: A surface device with a conversion structure (12) mounted on the substrate (2) but outside the surface of the substrate provided for surface wave propagation. The conversion structure eliminates undesirable surfaces which occur.

Abstract: A transducer for a filter arrangement with acoustic waves which includes a transducer 1 and 2 comprising groups (3, 4, 6 and 7) of alternating interdigitally spaced electrode fingers (10) in which the neighboring groups (3, 4 or, respectively, 4, 3 or, respectively, 6, 7) are arranged so that they are 80 degrees out of phase relative to each other at the fundamental frequency of the groups.
