Abstract: A portable or travelling transporting device for winding material usable as a hose truck has a frame (3), to which are fitted a travelling mechanism (4) with ground wheels (6) for moving on a ground surface, as well as a hose winding drum. The ground wheels (6) rotating on moving the hose truck can be brought into driving connection with the winding drum by means of a force transfer means (25) constructed as a flat gear. A slip clutch (46) located in the force transfer path ensures that during the advance of the hose truck a laid out hose can be wound onto the winding drum with a limited winding force appropriate for troublefree, compact winding on.

Abstract: A pond insert more particularly intended for insertion in a garden pond is described and which has at least one electromotively driven pump (2) The pump has an inlet connection and two intercommunicating outlet connections (5, 6), whereof one is preferably oriented horizontally and one vertically. The pump can be fixed in a basket-like container (3), which can be filled with a weighting material such as gravel or the like for improving the stability of the pond insert.

Abstract: A description is given of a rain indicator (1), which has a light source in the form of a light emitting diode (36) and a light detector in the form of a photodiode (37). There is a light guide (20) made from a material transparent to the light of the light source and e.g. glass, which has at least one surface portion (45, 46) exposed to the precipitation and which is so positioned relative to the light source that the light source light is totally reflectable towards the light detector on the surface portion. When the surface portion is dry light passes by total reflection to the light detector. In the case of precipitation a gap (43, 44) adjacent to the surface portion fills with liquid and the light intensity is substantially coupled out of the light guide (20) and no light passes to the light detector. Total reflection again occurs when the gap dries out.
