Abstract: Est décrite une méthode pour faire du dioxyde de titane soluble dans l'acide. La méthode comprend les étapes suivantes: (1) l'addition d'un composé de magnésium ou de manganèse à un minéral titanifère si le minéral ne contient pas suffisammemt de manganèse et de magnésium; (2) le chauffage du minéral en présence d'un agent de réduction pendant une période de temps suffisamment longue et à une température suffisamment élevée pour permettre la réduction des composés contenant du fer en fer métallique et permettre au dioxyde de titane présent de se convertir en une forme soluble dans l'acide; (3) le refroidissement du minéral; et (4) la séparation du fer du minéral au moyen d'une étape d'aération aqueuse. Le minéral titanifère contient du magnésium et du manganèse en quantité insuffisante quand l'expression suivante n'est pas satisfaite: 1,98a + 1,14b/d = 0,08 où a représente le pourcentage en poids de MgO contenu dans le minéral, (b) représente le pourcentage en poids de MnO contenu dans le minéral; et (d) représente le pourcentage en poids de TiO2 contenu dans le minéral. Le composé de magnésium ou de manganèse est soit un oxyde soit un composé qui est capable de se convertir en oxyde dans des conditions de réaction. Une technique d'aération aqueuse décrite dans la description de brevet comprend l'utilisation d'un séquestrant qui est capable de faire la séquestration du fer du minéral sans produire une baisse significative du pH local et en permettant en même temps la formation d'un oxyde de fer à un point éloigné du minéral. L'acide citrique est un exemple de ce type de séquestrant.

Abstract: A thin-film, flat panel, pixelated detector array serving as a real-time digital imager and dosimeter for diagnostic or megavoltage X rays or gamma rays, including a plurality of photodiodes made of hydrogenated amorphous silicon arrayed in columns and rows upon a glass substrate. Each photodiode is connected to a thin film field effect transistor also located upon the glass or quartz substrate. Upper and lower metal contacts are located below and above the photodiodes to provide the photodiodes with a reverse bias. The capacitance of each photodiode when multiplied by the resistance of the field effect transistor to which it is connected yields an RC time constant sufficiently small to allow fluoroscopic or radiographic imaging in real time.
