Abstract: A method for creating an electric heating source, including a body equipped with one or more housings containing mineral-insulated heating cables. The housings communicate with one or more reservoirs which accept a purely metallic solder material in solid, powder or sheet form. The device is heated in a vacuum degassing plateau, followed by a casting plateau during which the solder melts and fills the housing around the heating cables, resulting in full metal contact between the cables and the body, providing a more uniform temperature and a shorter response time to heating or cooling. Also, a heating source obtained in this manner, including an infrared faired source or an immersion heater for the heating of a liquid bath of molten metal.

Abstract: A terminal device for a cable with mineral insulation, including a metal bushing of which one end is intended to be secured to the end of the cable and a ceramic insulating element. The ceramic insulating element is a cylinder accommodated in the bushing, with one end projecting from the bushing and its opposite end, which has a bore, accommodated in the bushing, the end of the cylinder that is accommodated in the bushing having a tapered shape.

Abstract: A device for damping vibrations suffered by a cable and intended to be integrated into a recess for the cable that has a larger cross- section than the cross-section of the cable. The device has at least two tips with tubular cross-sections that are attached to the surface of the cable and a flexible portion connecting the tips together and extending to the interior wall of the recess.

Abstract: A capacitive sensor device for use at least up to 1300.degree. C. and 40 bar, including a coaxial cable comprising a conductive sleeve (10) and at least one inner conductor (21) which are separated by an insulator (19), said cable having an end portion (1) of enlarged diameter forming a probe in which the insulator is an anticorrosive refractory element (9, 29) locked by a first and a second anticorrosive refractory metal protection element (5, 4), welded to the sleeve and to said inner conductor, respectively, which second protection element forms an electrode (4) having a flat surface (4a) of an area larger than the cross-sectional area of the end portion of the inner conductor.
