Abstract

LA PRESENTE INVENTION CONCERNE UN DISPOSITIF DE RECHAUFFAGE ET DE MAINTIEN A LA TEMPERATURE DE 25 DU FILM "POLAROID" NOIR ET BLANC OU COULEUR, EN VUE DE RESULTATS PHOTOGRAPHIQUES CONSTANTS. CE DISPOSITIF SE COMPOSE D'UN CYCLINDRE APPLIQUE CONTRE LA BASE DE L'APPAREIL PHOTOGRAPHIQUE, CONTENANT DES RESISTANCES ELECTRIQUES CHAUFFANTES, ALIMENTEES PAR LE COURANT DU SECTEUR 110 OU 220 VOLTS. L'INVENTION A SON UTILITE DANS TOUS LES STUDIOS PHOTOGRAPHIQUES, POUR FAIRE LES PHOTOS D'IDENTITE, AVEC LES APPAREILS "POLAROID".
