    Abstract: Street-watering slide valve for actuating gas and water sluice valves with a telescopic linkage which is to be connected, at the lower end, to the slide-valve stem in a rotationally fixed manner and which - surrounded by protective tubes - terminates at the top in a surface box which is provided with a releasable cover. The telescopic portions of the telescopic linkage can be displaced freely with respect to one another in the longitudinal direction and the uppermost telescopic portion is suspended in the surface box in the same way as the upper portion of the protective tube, it being possible for at least the telescopic portion to rotate freely with respect to the surface box.

    Abstract: A stone block for creating curved walls or for laying curved paving patterns has a basic trapezium shape (10) with evenly angles sides and with integral break lines (5 to 8) to create smaller divisions of the parent block. The block is broken or cut along the break lines. The blocks can be made of natural stone, concrete or other suitable materials. The break lines can be used as a decorative feature and are between 0.5 and 10 mm deep. The parallel sides of the trapezium have lengths of about 10 to 30 cm for the smaller end and about 30 to 40 cm for the larger end. The sloping sides are about 125 cm long.
