Abstract: A two-stage method of recovering the noble metal content of a mixture of noble metals, for example, platinum, palladium, and rhodium, this mixture being, for example, comprised on or throughout a pellet or on or throughout a ceramic monolith of a spent catalyst, the method comprising first reductive chlorination at an elevated temperature by a gaseous chlorinating agent in the presence of a reducing agent (preferably the reducing agents sulfur dioxide and carbon monoxide in stages); minimizing the amount of aluminum trichloride formed from either washcoat or underlying ceramic chlorination, and separating the aluminum trichloride or other washcoat chlorides from the products of chlorination of the noble metals, as by sublimation of the former in a reducing atmosphere at a temperature below the vaporization temperatures of the latter, thereby recovering the noble metal chlorides in a concentrated form. As a second stage, temperature is further increased in an atmosphere of chlorine alone to volatilize rhodium trichloride for collection separately from the palladium and platinum chlorides volatilized previously in the first-stage reductive chlorination.

Abstract: A dough-stretching roller apparatus is provided to produce a continuous web of dough (7) in a process to manufacture confectionery and bread. The apparatus includes a pair of upper rollers (3), a sensor means (5) that detects the width of dough at the gap between the upper rollers (3), and a controller (11) that controls a motor (8) driving the upper rollers (3) in response to a signal from the sensor means (5). The controller (11) decreases the rotational speed of the upper rollers (3) when the sensors (5) detect that the width of dough is broader than a predetermined width of dough passing through the upper rollers (3), while the controller (11) increases the rotational speed of the upper rollers (3) when the sensors (5) detect that the width of dough is narrower than the predetermined width of the dough passing through the upper rollers (3). Thus, even if the amount of dough supplied from a hopper (2) is unstable, production of a stretched web of dough (7) having a constant volume per unit length can be stably continued.

Abstract: Matière photochromique adaptée pour recouvrir des matières transmettant la lumière. La matière photochromique contient des cristaux d'halogénure d'argent photosensible dont les dimensions se situent dans la plage comprise entre approximativement 50 Angstroems et 800 Angstroems. Les cristaux d'halogénure d'argent sont dopés en surface à l'aide d'ions cuivre ainsi que d'autres agents de sensibilisation choisis parmi des agents de réduction modérée, des thioéthers ou des ions porteurs de soufre, et ils sont traités à l'aide d'un agent afin d'accélérer la réaction avant et de maîtriser la réaction inverse. Les accélérants sont des ions sélectionnés dans le groupe composé de cobalt, de chrome, de manganèse, de magnésium et de métaux de terres rares telles que le cérium, le samarium et l'europium. L'agent destiné à maîtriser la réaction inverse est un agent conférant une conductivité électrique à la matière, et tandis que le glycérol contenant une concentration élevée d'ions métal, l'acide sulfonique de méthane et le chlorure d'ammonium benzyltriméthylique sont utiles à cette fin, l'agent préféré est l'acide phosphorique. Les cristaux sont dispersés dans un ou plusieurs polymères protecteurs ne se liant pas de manière irreversible à l'halogène.
