Abstract: Improvement to the development stage of thin film chromatography, development device for implementing such improvement and installation comprising this device. The thin layer chromatography development process entails contact being made under relatively even pressure between the chromatography developing plate and a suitable material impregnated with a suitable substance or developing reagent. The developing device for thin layer chromatography includes: porous material (20, 20', 72), which resists the ordinary chromatography development reagents and is absorbent enough to impregnate completely a chromatography plate without immersing it at the time of contact under pressure and to reabsorb the surplus reagent when the porous material is withdrawn from the chromatography plate; and a handling support (10, 11, 10', 11', 70) which is inert in relation to the development reagents and rigid enough to allow for suitable pressure to be placed on a thin layer chromatography plate and on which the porous material is mounted or fixed.

Abstract: Cartridges for use in ultrafiltration or reverse osmosis separation devices are formed by injection molding a generally tubular, smooth, seamless shell about a spirally-wrapped semipermeable membrane assembly. These cartridges can be used within traditional separation devices having pressure vessels of precise interior diameter, for which the cartridges are uniquely suited because they have cylindrical surfaces of true circular cross-section and close tolerances. The cartridges can also be created so as to incorporate integral pressure vessels and thus permit their use in separation processes without the need for surrounding supporting pressure vessels. A reaction injection molding process is shown which provides for substantial efficiencies in the overall manufacturing of semipermeable membrane separation cartridges of the spirally-wound variety. <IMAGE>

Abstract: Le flux de particules de métal en fusion du dispositif de diffusion est défléchi d'un bord à l'autre par un gaz sortant de deux buses disposées de manière diamétralement opposées par rapport au flux.

Les sections de passage des orifices d'admission et de sortie sont supérieures à la section de passage maximale de la rainure, de telle sorte que la quantité de gaz atteignant les buses à tout moment est déterminée par la surface efficace instantanée de la rainure (26). La limitation de la quantité de gaz libérée par les buses correspondant à une déflexion maximale de diffusion des particules de métal est toutefois déterminée par le total des sections de passage des buses de l'ensemble. Toute augmentation de la quantité de gaz libérée par les buses accroît la déflexion du flux de particules métalliques.

Abstract: A method and system is disclosed for converting a feed, such as a carbonaceous waste, to dissolved atomic constituents for subsequent oxidation of the dissolved atomic constituents. The feed is injected into a molten bath which, at a sufficient temperature, causes conversion of essentially all of the feed to its atomic constituents, such as atomic carbon. Essentially all of the atomic constituents which are to be oxidized in the molten bath dissolve in the molten bath. An oxidant is injected into the molten bath at a rate sufficient to cause the oxidant to exothermically react with the dissolved atomic constituents to heat at least a portion of the molten bath. The heated portion is thereafter exposed to subsequently injected feed, whereby essentially all of the subsequently injected feed is converted to atomic constituents, and whereby essentially all of the atomic constituents which are to be oxidized in the molten bath dissolve in the molten bath, thereby converting the feed to the dissolved atomic constituents for subsequent oxidation of the dissolved atomic constituents.

Abstract: A vertical-cavity surface-emitting laser is disclosed comprising a laser cavity sandwiched between two distributed Bragg reflectors. The laser cavity comprises a pair of spacer layers surrounding one or more active, optically emitting quantum-well layers having a bandgap in the visible which serve as the active optically emitting material of the device. The thickness of the laser cavity is m  lambda /2neff where m is an integer,  lambda  is the free-space wavelength of the laser radiation and neff is the effective index of refraction of the cavity. Electrical pumping of the laser is achieved by heavily doping the bottom mirror and substrate to one conductivity-type and heavily doping regions of the upper mirror with the opposite conductivity type to form a diode structure and applying a suitable voltage to the diode structure. For radiation in the yellow to green portion of the spectrum, the laser includes an active layer of GaP or AlGaP quantum wells and AlP/AlGaP mirrors. For radiation in the blue portion of the spectrum, the laser includes an active region of InGaN or GaN quantum wells and AlN/AlGaN mirrors.
