Title (EN) RADIOFREQUENCY WAVE TREATMENT OF A MATERIAL USING A SELECTED SEQUENCE OF MODES
(FR) TRAITEMENT PAR ONDES DE HAUTES FREQUENCES D'UNE MATIERE A L'AIDE D'UNE SEQUENCE SELECTIONNEE DE MODES
Abstract:
(EN) A radiofrequency wave apparatus including an applicator (112, 120) which provides multiple, sequenced processing modes is described. The modes in the applicator are selected to suit each stage of the processing of a material (B). The apparatus can include multiple currents (10, 11 and 12) which couple the radiofrequency waves to the applicator by means of probes (111a, 121a and 122a). The result is the optimum processing of the material.
(FR) Est décrit un appareil produisant des ondes hautes fréquences, comprenant un applicateur (112, 120), lequel produit des modes de traitements multiples en séquences. Les modes de l'applicateur sont sélectionnés pour s'adapter à chaque étape du traitement d'une matière (B). L'appareil peut comprendre des courants multiples (10, 11, et 12), lesquels couplent les ondes de hautes fréquences à l'applicateur au moyen de sondes (111a, 121a, et 122a). Le résultat est un traitement optimum de la matière.
