Abstract: The invention concerns a method of mowing meadows and the like, a method of composting cuttings, a mowing machine and a cuttings processing apparatus. A mowing machine according to the invention includes a driven rotating cutting member 4, a cuttings conveyor device 12 for transporting the cuttings into a compacting device 15, a chopping device 16 for the cuttings, a subsequent dehydrating device 17 and a liquid collecting and discharging device 19, 20 for the liquid extracted from the cuttings in the dehydration procedure.

Abstract: In an automatic seat-belt dispenser with a seat belt (7) that can be wound up and unwound, a multi-stage step-down gear is disposed between the winder shaft (1) of the seat belt and an energy storing (6), and a plurality of belts (2-3g, 3k-4g, 4k-5) are provided between the elements (2-5) of the gear. With this seat-belt embodiment, a linear and preferably linearly decreasing course of force with respect to the pulled-out length of the seat belt is attained.

Abstract: Device for guiding of air flow on vehicles, especially rear spoilers, with an air deflector which, in relation to the vehicle body, can be moved between a retracted position and an extended position in which the air deflector, as a whole, is away from the vehicle body and, in relation to its orientation in retracted position, is inclined. The air deflector is supported by an arcuate adjuster that is rigidly connected to it and which is slidably guided in a correspondingly arcuate guide channel of a guide block that is fixed with reference to the vehicle body.
