A procedure used to reduce the field of view of a [flame] detector by means of an opaque plate or card with a selected sized opening. This is frequently required to reduce refractory interference to acceptable levels.  2, fiche 3, Anglais, - orificing

The S512 with its PbS photo detector has a linear response from low to medium brightness flames, that is, no distortion of flame signal occurs with regard to any amplifier saturation or AGC action(compression). However, saturation will occur with the PbS element on bright flame. This condition can easily be rectified by using orificing(placing disk with small aperture in front of lens to reduce the amount of light or radiation).  3, fiche 3, Anglais, - orificing

Le convertisseur à résistance négative, étudié en préliminaire, est utilisé pour compenser les pertes d'un circuit LC, en particulier celles de l'inductance. On enregistre alors la «naissance» de l'oscillation qui permet de mettre en évidence la partie à croissance exponentielle et la stabilisation de l'amplitude due à la saturation de l'amplificateur.  2, fiche 4, Français, - saturation%20de%20l%27amplificateur
