Abstract: The system for removably securing slats juxtaposed to form a deck, for example for a terrace, includes fasteners disposed in rows on level floor or joist or beam structure supports oriented perpendicular to the axis of the slats. The fasteners have a device for securing the supports to the slats. A plurality of impermeable channels is disposed parallel for a level floor, or at a rate of one impermeable channel for each joist or beam support. The top surface of the support, a device for removable securing and a device for positioning provided on the profiled section are covered. The fasteners are made of a flexible elastic material, and the device for positioning allows clearance in a direction of an axis of the channel.

Abstract: The invention relates to an element for fixing (3) at least one modular coating blade (1) to a supporting structure (2), said element comprising: a base provided with a plane support face (6) to be fixed onto the supporting structure (2), and a fixing face (7) from which at least one protruding part (8) extends orthogonally, said protruding part to be engaged in a corresponding recess (4) in the blade (1). The projecting part (8) comprises tenons (10) on one free end (8c), said tenons progressively enlarging towards the fixing face (7) and facing an internal edge (19) of the recess (4), preventing the blade (1) from being removed.

Abstract: Method for the production of biaxially molecularly oriented polymeric film with more balanced tensile characteristics across the width, by subjecting the film between the longitudinal and the transverse stretching to an intermediate release treatment comprising maintaining the film at reduced longitudinal tension and at a temperature which is comprised between the second order transition temperature of the film and a temperature which is by 30.degree. C higher.
