A method for producing a winding, particularly for electrical transformer from a cylindrical tubular metal element of polygonal cross-section, includes steps of machining, in a first series of passes, a first series of cuts substantially parallel to one another through all of the sides of the tubular element with the exception of a last one of said sides, and machining, in a second series of passes, a second series of cuts in said last one of said sides in order to ensure that junctions of the first series of cuts open out in the sides adjacent to the second series of cuts, so that the first and second series of cuts are continuous with respect to one another and constitute a single groove of helicoidal shape.

An installation for heating grounds, in particular sports grounds, using cables () supplied with electric current which are buried in the ground. The installation is characterized in that the surface of the grounds to be heated is divided into a number of sectors (), and each sector is heated by at least two heating lines (&#x2033;) constituting each a secondary of a common transformer (et).

Device for heating grounds, in particular sports ground

A false wall includes a stretched piece of fabric held on the periphery thereof by an edge attachable to ribbands fixed to the ceiling or walls of a building. The ribbands include a holding arrangement having two interspaced parallel wings, namely a first external large wing and a second, lower, internal wing that ends in a shoulder extending towards the first wing and ending at a distance there from that enables the edge to be guided through, to rest on the shoulder. The ribband includes a base and two holding arrangements provided with inclined wings that converge towards each other and the space between the ends thereof is such that the distance between the end of a large wing and the plane of the large wing of the holding arrangement opposite is equal to the distance separating the shoulder of the holding arrangement from the large wing associated therewith.

False walls consisting of stretched fabric and joined by an inclined separating ribband

A structural profiled section, in particular for partitions, has cross-with two parallel U-shaped parts designed to receive the partition panels. The inner branches of the U-shaped parts are assembled by a transverse junction element arranged at a short distance from their respective bases.
