Abstract: Ion exchange resin particles bearing ion exchange groups only in the most accessible portions of the particles possess kinetic advantages over fully functionalized resins in continuous-flow treatment of fluids. Resin beads are functionalized in an outer region that is from 32 to 73% of the bead radius thick: non-spherical or macroporous particles are similarly functionalized in a layer that is adjacent to the outer surface of the particle or to the surface of the macropores. Such a functionalization is obtained using a reagent system in which the functionalization rate is faster than the rate of diffusion of the reagent into the particle, and stopping the reaction when from 68% to 98% of the most readily accessible, functionalizable sites are functionalized.

Abstract: Circuit for recognising a line-synchronising signal in a video signal in which a synchronising signal is sent to a phase-lock loop comprising an oscillator (8) with a voltage-controlled frequency (VCO) in order to deliver a line-scan signal to a display means. The invention provides for disabling the operation of the loop and causing the VCO to oscillate at its natural frequency, in the absence of the line-synchronising signal; producing a detection window related to the oscillation of the VCO; and detecting the presence of the synchronising signal in this window in order to deliver, either a validation signal following detection of a chosen number of synchronising pulses, this validation signal bringing back into circuit the VCO in the loop, or a disabling signal if said detection is interrupted during the said chosen number of synchronising pulses. …<IMAGE>…

Abstract: The approximately 23% strength waste sulphuric acid (DS) produced in the digestion of titanium raw materials is concentrated to about 70% by weight (CS) and is subjected together with precipitated metal salts completely or at least to a large extent to roasting (R). While the metal oxides (MeO) formed are deposited, the sulphur oxide gases produced are reacted with water to give highly concentrated, for example 98% strength, sulphuric acid (HCS), which is recycled into the digestion of titanium raw materials. Since the proportion of recycled metal compounds is substantially reduced in recirculation, a titanium dioxide pigment of higher quality can be produced with less complicated equipment and less energy. <IMAGE>

Abstract: La présente invention se rapporte à un nouveau procédé servant à préparer un pro-catalyseur soutenu d'un système catalytique destiné à la polymérisation d'oléfines, dans lequel le produit de réaction formé par de l'halogénure de magnésium et un alcool est traité pour retirer l'alcool et est activé au moyen d'un composé métallique de transition et éventuellement d'un donneur d'électrons. Dans les solutions actuelles, le composé métallique de transition réagit avec l'alcool ainsi qu'avec le chlorure de magnésium et sert en plus de milieu pour séparer le produit dérivé formé par lui-même et par l'alcool. Le problème qui se pose alors est que de grandes quantités du métal de transition sont perdues et que ce produit dérivé constitue un déchet dangereux difficile à traiter. La présente invention résout ces problèmes en retirant l'alcool à l'aide d'une étape de pulvérisation-évaporation séparée. L'étape de pulvérisation-évaporation est de préférence effectuée avec des pulvérisateurs à jet utilisant un gradient thermique pour le gaz.
