Title: A method and an apparatus for excitation of a plasma
Inventor: WINTHER-JENSEN BJ SLZERORN
IPC: B01J19/08
Filed: 2001-10-27
Abstract: A method of exciting a plasma, wherein a gas is subjected to an electrical field generated by means of a plurality of electrodes. One electrode is form ed by an outer metal pipe (1). This outer metal pipe (1) surrounds one or more inner metal pipes (2) which form the other electrode. The idea is to turn it  to account that plasma is generated in one or more of the inner pipes. These  pipes are easier to clean, and the cleaning process is therefore simplified considerably. To this should be added that the distance between the electrod es may now be increased considerably, thereby reducing the risk of breakdown between the electrodes.

Title: Method and apparatus for change-over of the molten metal coating composition in a steel strip coating line
Inventor: GARZA-DAVILA JOSE CARLOS
IPC: C23C2/40
Filed: 2003-11-06
Abstract: A method and apparatus for rapid and efficient. changing-over the coating molten metal in a continuous steel strip coating line from a first aluminum-based coating composition to a second zinc-based coating comprising a first ceramic-lined tank provided with heating means for controlling the temperature of the molten metal in said first tank and a second smaller removable tank without heating means for containing said second coating molten metal adapted to be placed within said first tank, wherein the wall of the second removable tank is effectively heat conductive and preferably has a wall downwardly converging so that its positioning within the first tank is facilitated and damage to its ceramic lining is avoided. The weight of the second tank is mostly supported by the floating forces of the molten bath in said first tank. During use of the second tank, the composition of said first bath is adjusted away from its coating composition by removing a large portion of the aluminum-zinc content and adding zinc to the remaining bath; so that its melting point is lowered to prevent solidification at the zinc coating temperatures, preferably to within 400°C and 480°C and its density is preferably in the range of 5.5 to 6.0 tons/m3. The volume of the second tank is designed so as to simplify the adjustment of composition of the first bath by withdrawing a predetermined volume of the aluminum-based coating metal (sufficient to accommodate the placement and immersion of the second tank in the first tank) and adding molten zinc thus obtaining the desired melting temperature and density and filling volume in the first tank.

Title: Procede de modification d'administration de traitement radiotherapique
Inventor: HUGHES JOHN H
IPC: G06T1/00
Filed: 2003-03-06
Abstract: L'invention concerne un nouveau procédé de repositionnement de dose anatomique profilée (CADR) utilisé en tant que moyen destiné à repositionner automatiquement un patient afin de mieux rétablir une administration de dose prévue sans réoptimiser le plan de traitement. La technique CADR met en oeuvre en particulier des images tomodensitométriques, l'administration de dose prévue, et des images en ligne permettant de repositionner l'administration de dose pour un jour donné. Des profils sont également placés sur les images au moyen de techniques manuelles, automatiques, basées sur un modèle, ou autres. La technique CADR optimise ensuite le repositionnement du corps rigide du patient de sorte que l'administration de dose quotidienne corresponde étroitement avec l'administration de dose prévue. L'invention concerne également un procédé d'optimisation multimarge à sélection quotidienne (MMODS) destiné à améliorer l'administration de rayonnement sans réoptimisation. Pendant la procédure initiale d'optimisation, des plans sont optimisés pour plusieurs marges de plusieurs profils (par exemple serré, intermédiaire, relâché, etc.) ou avec des objectifs différents (par exemple traitement agressif, économie de structure sensible, etc.). De la même manière, si plusieurs ensembles d'images de patients sont disponibles, des plans peuvent être optimisés pour les représentations anatomiques différentes, au moyen d'informations ponctuelles ou d'informations accumulées associées à la superposition d'emplacements d'organes dans la combinaison d'images. Un utilisateur peut ensuite choisir en temps réel parmi une variété de plans optimisés, généralement avec des marges différentes, pendant le procédé de traitement, et ainsi compenser une modification reconnue dans la taille ou la position d'une tumeur ou d'un tissu avoisinant.
