  • Publication number: 20140212274
    Abstract: A device for axial locking of a moving part in rotation with respect to a reference part, includes a downstream locking wedge provided with lugs laid out such that the downstream locking wedge can be placed in: a first angular position in which the downstream locking wedge may be translated axially with respect to the moving part, a second angular position in which the lugs axially immobilise the downstream locking wedge with respect to the moving part; an upstream locking wedge able to prevent the rotation of the downstream locking wedge with respect to the moving part; and a stop segment able to immobilise axially the upstream locking wedge against the downstream locking wedge.

  • Patent number: 8540813
    Abstract: An ink for the engraved copperplate intaglio printing inks is disclosed, which comprises high-molecular-weight dendritic polymer as a binder component. Inks comprising such polymer can be formulated so as to contain a significantly reduced amount of organic solvent (volatile organic components, VOC) while still being in the appropriate viscosity range required by the intaglio printing process. The printed and cured intaglio ink of the present invention has improved chemical and mechanical resistance properties.

  • Publication number: 20120308072
    Abstract: The present invention is related to a device useful as a security element comprising first and second LC ink layers representing a graphical object exhibiting, when observed with an appropriate viewing equipment, a three-dimensional appearance, wherein one of said ink layers shows a first color at a certain viewing angle and is a left-handed circularly polarizing coating or comprises left-handed circularly polarizing pigment, and the other of said ink layers shows the same or another color at said viewing angle and is a right-handed circularly polarizing coating or comprises right-handed circularly polarizing pigment, said first and second LC ink layers representing a first and a second image corresponding to a pair of stereoscopic projections of said object, characterized in that said first and second images are composed of separate building blocks which are superimposed or can be superimposed.
