Abstract: The invention relates to a composite tile for an installation system, more particularly for the production of a floor covering or wall covering, comprising a tile of a floor covering or wall covering and a backing disposed on the lay-on face of the tile. The invention also relates to a connecting element for the connection of two composite tiles and to an installation system composed of composite tiles and also to a method for the fabrication of a composite tile. The backing consists of a fiber composite material, more particularly fiber cement.

Abstract: The invention relates to a paving system for tiles, especially flagstones, for paving ceilings, walls, or floors, in which each tile (2) is provided with a paving frame (1) on which the tile rests over at least part of its area. The paving frames (1) comprise, on each of two adjacent (intersecting) limbs (1c, 1d), a fin (6) for the accommodation of a rubber-elastic sealing profile (8) that defines the width of the seam.

Abstract: A shifting coupling which is preferably provided for the travel mechanisms of overhead conveyors, and which operates in a positively engaging manner counter to a spring which acts in the disengagement direction. The coupling projections or engaging members, which are provided on a coupling flange, are controlled with the aid of two sleeves which are movable relative to one another. Those ends of the sleeves which butt against one another are provided with oppositely extending conical surfaces. Control balls can be pressed into the wedge-shaped recess which results between the two conical surfaces. The control balls press the two sleeves apart in order to engage the coupling. A control sleeve, which is provided with inner conical and annular surfaces, serves for the radial movement of the control balls. During the engagement process, the control sleeve is resiliently prestressed in such a direction that the conical surface thereof contacts the control balls in the direction of coupling engagement.
