Abstract: A heat-exchange device (2) for a laundry treatment machine includes a first heat exchanger (4) and a second heat exchanger (6) that are disposed successively along a flow path (10) of process air in an operating state of the heat-exchange device (2), and are connected to each other by a connecting plate (8). The first heat exchanger (4) includes a first side plate (12), and the second heat exchanger (6) includes a second side plate (14), wherein the first and the second side plates (12, 14) are each disposed on a side of the heat-exchange device (2) opposite the connecting plate (8) and are disconnected at least in a pre-installation state of the heat-exchange device (2). A base module is configured to fix the relative position of the first and second heat exchangers (4, 6) with respect to each other.

Abstract: A length compensator for pipelines, preferably plastic pipelines, containing two connecting components, preferably made from plastic, a compensating element made from an elastic material, preferably a thermoplastic elastomer (TPE), and a supporting pipe, wherein the compensating element is arranged between the two connecting components and the compensating element ends are connected to the connecting components, wherein the outer lateral surface of the compensating element is suitably encompassed by the inner lateral surface of the supporting pipe around its entire circumference, wherein the supporting pipe has a circular cross-sectional area and the compensating element expands and contracts exclusively in the axial direction.

Abstract: A system containing a writing and reading unit with an antenna coil and at least one preferably elastic carrier in the form of a strip, on which is provided at least one mobile data memory which has a memory and operating circuit and, connected thereto, an elongate loop coil. The arrangement has the advantage that the mobile data memory can be provided on surfaces having virtually any degree of undulation. If a mobile data memory of this type encloses the circumference of a cylindrical object, then data transmission can be carried out in any desired radial spatial direction. The device is particularly suitable for identifying gas cylinders, in which case the elastic carrier, in the form of a strip, of a mobile data memory is placed around the casing of each gas cylinder, particularly in the region of the neck rings thereof.
