Abstract: A tread element for a moving pavement or an escalator has a tread plate adapted to receive the person to be transported. The tread plate has a nosing secured to it along at least one of its longitudinal edges. In one embodiment, the nosing is secured to the tread plate by a longitudinal hook engaging the underside of the tread plate, a plurality of plugs passing through slots in the tread plate and secured underneath by stops such as a clamp-ring, and a plurality of centering projections which engage under a portion of the tread plate along the upper surface. The compact step is a single die-casting, which does not have to be completely removed and replaced in the event of breakage of the tread plate ribbing in the outer zone of the tread plate.

Abstract: In order to provide a secure connection which can be produced in a simple manner by the pressure die casting method between edge strips (3) inserted in the step plate (2) of a step element and the step plate (2), the edge strips (3) have on their underside at least along their two longitudinal edges a respective tongue (6, 7). The cross sections of the latter two have the shape of a parallelogram with mutual identical angles or of a trapezoid and engage in corresponding grooves (8, 9) in the step plate (2) in the manner of a tongue-and-groove connection. Furthermore, these edge strips (3) are provided on their underside moreover with at least two cast-on locking pins (10) which extend downwards and through the adjacent step plate (2), and on whose free ends projecting downwards out of the step plate (2) a respective clamping ring (11) is clamped resiliently supported on the underside of thhe step plate 2.

Abstract: A two-cycle internal combustion engine operated with a fuel mixture having exhaust gas turbo charging. To inhibit carbon fouling of the exhaust gas turbine, a turbine wheel housing is arranged inside the exhaust manifold. To balance the resultant heating of the turbo charger compressor, the cooling system of the engine is directed so as to cool the compressor housing and intake manifold. The intake manifold system and exhaust system are tuned to the engine so as to set up periodic vibrations which provide dynamic charging and rinsing of the cylinder.

Abstract: A weather protection system for a road vehicle has windows, including a wind screen pane and a rear window pane, and comprises at least two protector parts which are detachably connected to the vehicle, are composed of flexible material, extend at least over the vehicle windows, and are disposed near each other in the region of the windscreen pane and the rear window pane.
