Abstract: Grate plate for the push-type grate of a clinker cooler, which has a topside bearing surface exposed to the hot material to be cooled. The grate plate including a rear region having devices for connection to a grate-plate carrier, such that the grate plate front projects over an adjacent grate plate. Longitudinally extending edge strips are connected in a force-transmitting manner to the devices for connection to the grate-plate carrier to support the plate front. The topside bearing surface is formed by a cover plate which is free of the edge strips, at least in front of the grate-plate carrier, and which has freedom of expansion in the horizontal direction in relation to the support part comprising the edge strips.

Abstract: A fun-ride and more especially a roller coaster or a similar fun-ride, in the case of which the amusement potential is simply enhanced because the basic or original type of movement, that is to say travel of a vehicle cabin on rails of a roller coaster is combined with a further and different types of motion is discontinued or then alternatively continued with such different type of motion. Figure along the travel path, that is to say for example along the elevated rails of a roller coaster, at one or more points additional ride change means are provided, which produce the additional or alternative type of motion for the vehicle cabin.

Abstract: Described is a grating plate for a sliding grating for a burned-material cooling unit, the grating plate having, in the surface which holds the materials, a recess (13) in which cooling-air outlets (10) are located and, below the recess, a cooling-air feed space (17). The depth of the recess (13) increases from back to front. The cross-section of the cooling-air feed space (17) decreases correspondingly from back to front in accordance with the change in the cooling-air flow through the space.
