Abstract

L'APPAREIL SELON LA PRESENTE INVENTION COMPREND UN CIRCULATEUR 1 AUQUEL SONT RACCORDES, RESPECTIVEMENT, PAR DES OUVERTURES 2, 4 ET 6, UN MAGNETRON 3, UN GUIDE D'ONDES RESONNANT FERME 7 ET UNE CHARGE FICTIVE 5. LA MATIERE A SECHER PASSE A TRAVERS LE GUIDE D'ONDES A TRAVERS DES FENTES 9 MENAGEES DANS LES GRANDS COTES DE CE DERNIER, LE GUIDE D'ONDES ETANT ACCORDE DE TELLE MANIERE QUE LES VENTRES DES ONDES STATIONNAIRES SE TROUVENT A DES ENDROITS VOULUS CORRESPONDANTS A DES ZONES EXIGEANT UN PLUS GRAND SECHAGE. APPLICATION : SECHAGE DES PELLICULES PHOTOGRAPHIQUES, DES TEXTILES, DES CIGARETTES, ETC.THE APPARATUS ACCORDING TO THE PRESENT INVENTION CONSISTS OF A CIRCULATOR 1 TO WHICH ARE CONNECTED, RESPECTIVELY, BY OPENINGS 2, 4 AND 6, A MAGNETRON 3, A CLOSED RESONANT WAVE GUIDE 7 AND A FICTIVE LOAD 5. THE MATERIAL TO BE DRY PASSED TO THROUGH THE WAVEGUIDE THROUGH SLOTS 9 CONDUCTED IN THE LARGE SIDES OF THE LATTER, THE WAVEGUIDE BEING GRANTED SO THAT THE VENTURES OF THE STATIONARY WAVES ARE LOCATED AT DESIRED LOCATIONS CORRESPONDING TO ZONES REQUIRING GREATER DRYING. APPLICATION: DRYING PHOTOGRAPHIC FILMS, TEXTILES, CIGARETTES, ETC.
