Abstract: A process for manufacturing a composite profile based on a thermoplastic organic material reinforced by reinforcing fibres includes making a multiplicity of continuous reinforcing yarns come into contact with a thermoplastic organic material and shaping the composite profile. Continuous yarns based on continuous glass fibres and on a first thermoplastic are brought together to be parallel and at least one consolidated tape is formed by heating them, in which tape the reinforcing fibres are impregnated with the first thermoplastic. The at least one tape is introduced into a die sized to the cross-section of the profile and at least one second molten thermoplastic organic material is simultaneously introduced into the die in contact with the tape, to obtain a profile of at least one second thermoplastic organic material reinforced by the at least one tape.

Abstract: The invention relates to a glass substrate having on at least one of its faces an antireflection coating formed by a stack of thin dielectric material layers having alternately high and low refractive indices. To prevent the modification of the optical properties of the coating in the case where the substrate is subject toga heat treatment such as tempering, bending or annealing, the layer or layers of the stack which are liable to deteriorate on contact with alkali ions such as sodium ions are separated form the substrate by at least one layer forming part of the antireflection coating and forming a “shield” with respect to the diffusion of alkali.

Abstract: A window frame is formed of a plurality of plastic section pieces welded together at their ends. The ends of the plastic section pieces also have surfaces which abut one another. The plastic section pieces are not welded at the abutting surfaces. The unwelded abutting surfaces can therefore be used to define the length of the window frame.

Abstract: This invention concerns an electrochromic pane comprising a principal functional film constituted of a material which, under the effect of an electric current, is capable of reversibly inserting cations and which has characteristics of coloration and/or transmission in certain wavelengths of electromagnetic radiation that differ for its inserted and deinserted states. Said principal functional film has a quasi-columnar structure, with axes of growth of the columns parallel to straight lines contained within a dihedron, the opening of which is less than 20.degree., and the bisector plane of which makes an acute angle with the substrate.
