Abstract: Process and apparatus for transiently measuring surface temperatures and heat flux at the interface of two media, one of which is solid. In a solid wall through which a thermal stream flows, a cut is made which opens into the interface between the wall and the other medium. The cut is parallel to the stream at a point of contact corresponding to the interface. A microthermocouple is arranged in a plane of the cut in the immediate vicinity of the interface. The cut is closely covered by the material of the solid wall or a material with thermal characteristics similar to those of the peripheral material.

Abstract: The invention relates to elongated textile elements having one or more thickened portions along its length, processes for their manufacture and the articles produced with such elements.The element is characterized in that it consists of an assembly of substantially parallel yarns of high bulk, which possesses, over its length, at least two compressed zones of low diameter separated by a bulky zone of high diameter.These elements, used by themselves or in association with other materials, make it possible to obtain very decorative articles suitable for garments and especially for furnishings such as tapestries, wall coverings, seat covers and the like.
