    摘要: The supporting and suspending frame, detachably assembled from a plurality of supporting frame elements, serves to suspend flat reproductions, in particular photographic reproductions, of paper, film or fabric smoothly in the frame by means of tensioning springs. Every supporting frame element has an at least partly circularly curved narrow side and a contiguous flat wide side at right angles thereto. The inside face of the wide side is provided with a supporting member that extends in the longitudinal direction of the wide side and is open in the transverse direction of the wide side. The tensioning springs, which are fastened to the edges of the reproduction by means of eyes, can be suspended directly in and displaced along the supporting member. As a result, it is possible to wrap the reproduction over the wide side and the narrow side toward the back side of the supporting frame element and there fasten it smoothly by means of the suspended tensioning springs, so that the reproduction is clamped or displayed in a "borderless" manner.

    摘要: A driving device for rail vehicles having both a friction drive and a cog gear drive has a common drive shaft placed in the longitudinal direction of the rail vehicle. The drive shaft is provided with driving worms which mesh with worm gears on the driving axles of the friction drive and the cog gear drive. The worms are axially spaced on the drive shaft and engage the respective drive gears of the friction and cog gear drives which are located under the drive motor so as to obtain greater traction force with the friction drive and a more positive meshing of the cog gear with the rack.

    摘要: A coupler for rail vehicles of a model railway is attached to the end of a vehicle along substantially the longitudinal central axis of the vehicle. The coupler is provided with a coupling carrier which has at its free end a coupling plate acting as a buffer. In the coupled condition of railway vehicles, these coupling plates abut against each other and coupling hooks are positioned behind the coupling plates to retain the vehicles in coupled relationship.
