Abstract

DANS UN SENSITOMETRE COMPORTANT UN COUVERCLE 2 ET UN BOITIER 1 ENTRE LESQUELS PEUT ETRE PLACEE UNE PELLICULE PHOTOGRAPHIQUE A MESURER, LE COUVERCLE PEUT ETRE ACTIONNE D'UNE MAIN ET ENCLENCHE, LORSQU'IL EST ABAISSE, UN INTERRUPTEUR 20 A TEMPS POUR L'ALIMENTATION D'UNE PLAQUE ELECTROLUMINESCENTE QUI SERT DE SOURCE LUMINEUSE 7 POUR LA PROJECTION D'UNE ECHELLE DENSITOMETRIQUE 6 SUR LA PELLICULE PHOTOGRAPHIQUE. POUR L'INDICATION, ON UTILISE UN RONFLEUR 24. LE COUVERCLE ET LE BOITIER SONT ARTICULES L'UN A L'AUTRE DE MANIERE TELLE QUE DANS L'ETAT DE FERMETURE LE BOUT DE FILM SOIT PRESSE A PLAT D'UNE MANIERE ETANCHE A LA LUMIERE CONTRE L'ECHELLE DENSITOMETRIQUE ET QUE DANS LA POSITION DE REPOS, LE COUVERCLE SOIT QUELQUE PEU OUVERT. APPLICATION: SENSITOMETRIE DE MATERIEL PHOTOGRAPHIQUE.IN A SENSITOMETER CONTAINING A COVER 2 AND A BOX 1 BETWEEN WHICH A PHOTOGRAPHIC FILM TO BE MEASURED MAY BE PLACED, THE COVER CAN BE ACTUATED WITH ONE HAND AND LOCKED, WHEN IT IS LOWERED, A SWITCH 20 IN TIME FOR THE POWER SUPPLY 'AN ELECTROLUMINESCENT PLATE WHICH SERVES AS A LIGHT SOURCE 7 FOR THE PROJECTION OF A DENSITOMETRIC SCALE 6 ON THE PHOTOGRAPHIC FILM. FOR INDICATION, A SNORER 24 IS USED. THE COVER AND THE HOUSING ARE HINGED TO ONE ANOTHER SUCH THAT IN THE CLOSED STATE THE FILM END IS PRESSED FLAT WATERTIGHTLY. LIGHT AGAINST DENSITOMETRIC SCALE AND THAT IN THE REST POSITION, THE COVER IS SOMEWHAT OPEN. APPLICATION: SENSITOMETRY OF PHOTOGRAPHIC EQUIPMENT.
