Abstract: Detecteur de controle de la fonction du stator et des diodes de redressement dans un systeme de charge (20) d'une batterie a partir d'un alternateur multi-phase. Un circuit combine des signaux de phase individuels de l'alternateur (22) pour former un neutre artificiel ou un signal d'onde normalement symetrique est present. Des premiers moyens de comparaison detectent des deviations dans le signal d'onde normalement symetrique d'une valeur superieure a un premier niveau de tension de seuil. Des seconds moyens de comparaison detectent des deviations dans le signal d'onde normalement symetrique inferieures a un second niveau de tension de seuil. Des moyens couples au premier et au second comparateur produisent un signal de sortie toutes les fois que le signal d'onde normalement symetrique devie d'une valeur superieure au premier niveau de tension de seuil ou inferieure au second niveau de tension de seuil. La detection d'asymetrie dans le signal d'onde normalement symetrique indique une defaillance dans le stator ou les diodes de redressement de l'alternateur.

Abstract: Des compositions photographiques de protection ou reconstitution polymerisables par radiation consistent en un urethane acryle, un acide carboxylique aliphatique ethyleniquement non sature, un acrylate multifonctionnel, et un polycarbinol contenant un siloxy. Des elements photographiques, tels que des films inanimes, des films a image mobile, des impressions sur papier, des microfiches et autres, sont pourvus d'une couche de revetement de protection qui est liee en permanence a l'element, et sert a le proteger contre l'abrasion et les egratignures, en revetant l'element avec la composition polymerisable par radiation et en irradiant le revetement pour le lier sur l'element et le polymeriser pour former une couche polymere reticulee transparente, flexible, resistante aux egratignures. La couche de revetement de protection peut etre appliquee sur le cote portant l'image de l'element ou sur le cote support de l'element ou sur les deux cotes. La composition polymerisable par radiation est egalement reconstituante et peut etre revetue sur des elements photographiques qui ont des egratignures, des traces d'abrasion et autres, ce qui porte atteinte aux caracteristiques d'aspect ou de projection de l'element. En reconstituant l'aspect des elements photographiques, la composition polymerisable par radiation peut etre appliquee localement dans la region des defectuosites seulement, pour les eliminer effectivement et reconstituer l'element en lui redonnant un etat sensiblement parfait, ou elle peut etre appliquee sur toute la surface de l'element pour a la fois eliminer les defauts et former une couche de revetement de protection pouvant le proteger contre d'eventuelles egratignures ou abrasions.
