Abstract: A device assists in target acquisition by an operator in a weapon system comprising a target detection and locating system that delivers target-locating data, said device comprising means to synthesize stereophonic signals intended for the operator and means to convert target-locating data into data controlling the synthesis of stereophonic signals so that the operator is given a subjective sensation of a direction of attack corresponding to the actual direction of the target with respect to this operator.

Abstract: An oven is provided for baking a substrate having a printed circuit obtained by depositing on an insulating substrate, by silk screen printing, an insulating or resistive ink comprising an organic material which forms a temporary binder of this ink, which oven is provided with gas injection means for baking in the desired atmosphere, means for extracting the reducing gases and/or baking residues obtained by transformation of the organic materials under the effect of the temperature, and means for sweeping these reducing gases in the direction of the extraction means so as to accelerate removal thereof without creating any zone of stagnation or turbulent flow.
