Abstract: Thermal insulation screen transparent to magnetic flux, intended to isolate an electromagnetic inductor with a transverse or pseudo-transverse field, from the radiation of a heated product (1), the thermal screen being made up of a matrix of blocks (7) made of a thermally insulating material and of a plurality of tubes (8) cooled by the circulation of a fluid, these tubes being imprisoned in said matrix of blocks and the tubes and the blocks being held in place by a support. The screen includes, behind the blocks, heat-conducting means (10) placed so as to intercept the heat flux passing through the blocks, these conducting means being thermally coupled to the cooled tubes (8) for discharging the heat flux into the tubes.

Abstract: A heating device for the electromagnetic induction heating of a metal strip traveling in a specified direction. The device includes at least one electric coil arranged opposite at least one of the large surfaces of the strip so as to heat the latter by transverse magnetic flux induction, each coil being associated with at least one magnetic circuit. Each circuit is divided into a plurality of magnetically independent bars arranged parallel to the direction of travel of the strip. The bars may moved toward or away one another thereby adapting to the width of the strip and distributing the magnetic flux across the width of the strip.

Abstract: A feed device for an injection chamber of a pressure die-casting or injection machine or for a press tool or a forging press die transfers a billet into an injection chamber or die press. The billet may be of metal or plastic, filled or unfilled, and in a liquid, solid, semi-liquid or semi-solid state. A support with a horizontal axis receives and houses the billet. A ram moves the support and thus transfers the billet into at least one heating system. The ram that transfers the billet also moves the support in a horizontal translational motion transporting the billet from the heating position to a position lying vertically above the injection chamber of the tool or the press die, and then moves the support with a rotational motion about its axis so as to cause the billet to drop, horizontally, due to gravity, from the support into the injection chamber or into the press die.

Abstract: An induction heating device for continuously moving metal strip (22) for heat treatment or coating purposes comprises a flattened, spirally wound coil having the turns interlinked by an oblique connection on a small side of the coil, and surrounding the continuously moving metal strip (22). Means (24-26) are provided for suppressing the transverse component of the magnetic field created by the said coil.
