  • Patent number: 5203640
    Abstract: This invention relates to a profiled strip adapted to be used for making the join between two surface coverings making therebetween a determined re-entrant angle, wherein this profiled strip comprises: two bearing sole plates which are made of a hard, semi-rigid material, which are each adapted to be placed below one of the surface coverings and which each present an extension extending in a direction offset angularly by substantially 90.degree.; and a connecting bridge which connects the extensions, which is made of a supple material and which maintains the bearing sole plates angularly offset with respect to the re-entrant angle.One application of the invention is the production of a profiled strip for joining the tiles of two vertical walls.

  • Patent number: 5187905
    Abstract: This invention relates to a complex sound-insulating material comprising a first lower sub-assembly, itself comprising at least one layer of a bituminous product, and a second upper layer which covers said first sub-assembly. The first sub-assembly comprises a first upper layer, a first intermediate layer and a first lower layer, whilst a) each of the first upper and lower layers is made of oxidized bitumen reinforced with first fibers and has a surface mass of between 500 and 1000 g/m.sup.2 ; b) the first intermediate layer is made of an organic binding agent, such as a bitumen, and by second fibers which are embedded in said binding agent and are in a non-woven form; and c) the second upper layer is made of an elastic foam.One application of the invention is the production of a sound-insulated tiled flooring.

  • Patent number: 5181357
    Abstract: This invention relates to a profiled strip particularly adapted to compensate the relative displacements of surface coverings with respect to the walls, wherein said profiled strip comprises: a generally flat sole plate; two principal limbs which extend from the sole plate, perpendicularly thereto; a bridge for connecting the ends of said principal limbs and two secondary limbs which extend substantially parallel to the sole plate, from the principal limb most remote from the free edge of the sole plate, these two secondary limbs having substantially equal widths; the sole plate and the principal limbs being made of a hard, semi-rigid material, and the connecting bridge being made of a supple material.One application of the invention is production of the zone of connection between a tiled floor and partition.

  • Patent number: 5144778
    Abstract: This invention relates to a profiled strip adapted to be used when laying tilings or other like surface coverings, wherein this profiled strip comprises: a bearing sole plate which is defined by a lower face, an upper face and an edge; a bead which, opposite the edge, is upstanding from the upper face of the bearing sole plate and its outer shape is that of a quadrant; and a counter-joint which is upstanding from the upper face of the bearing sole plate and constitutes the inner limit of the bead and of the bearing sole plate.One application of the invention is the production of profiled trims having a good resistance in time.

  • Patent number: 5130186
    Abstract: This invention relates to a material for use in the production of a flooring in a building construction.According to the invention, this material comprises an upper layer, an intermediate layer and a lower layer, while: a) each of the upper and lower layers is made of oxidized bitumen reinforced with first fibers and has a surface mass of between 500 and 1000 g/m.sup.2 ; and b) the intermediate layer is made of an organic binding agent, such as a bitumen, and by second fibers, which are embedded in said binding agent and are in non-woven form.One application is constituted by the laying of a tiling not subject to the development of cracks.

  • Patent number: 5040521
    Abstract: This invention relates to a machine for cutting tiles, particularly sandstone ones, comprising: a guide rail; a cutting assembly mounted to move along said guide rail, guided by this guide rail and provided with a cutting tool; and a member for breaking the tile after scoring, which comprises two bearings flanges, which is mounted to be adjustable in position with respect to said cutting assembly and which may occupy two positions: a first position, in which the bearing flanges do not bear on the surface of the tile to be broken, and a second position in which, on the contrary, said bearing flanges are in contact with the surface of the tile to be broken, on either side of a longitudinal plane of the cutting assembly passing through the cutting tool and are in such abutment on the surface of the tile as to cause said tile to break. According to the invention, the breaking member is mounted on the cutting assembly itself. One application is the production of a machine making good-quality cuts.

  • Patent number: 4723332
    Abstract: The invention relates to a multi-purpose tool constituted by a U-shaped frame with two branches joined together by a bar, one branch being extended by an appendix parallel to the bar and equipped at its end with a drilling tool, by a handle assembly extending from the end of the second branch in parallel to the bar and comprising a handle adapted to be either integral with the frame or mounted for rotating thereon, and by an elongated cutting tool with two ends fastenable on the ends of the two branches of the U-shape.The handle comprises a rod of which one threaded end is provided with a shoulder, whereas close to its end, the second branch of the U-shape is provided with a hole traversed by the threaded end of the rod until it contacts the shoulder part, a nut being provided to optionally hold said rod in position on the frame and to selectively immobilize it thereon.The invention finds an application as a tool for drilling an cutting earthenware tiles.
