BOPI 04 BR/2023 REPERTOIRE NUMERIQUE 33 spaced apart from each other to define a gap between them through which the pipeline extends. A removable lifting frame (12) is mounted on the foundations to bridge over the pipeline disposed in the gap. The lifting frame comprises a pair of feet (32) that are cooperable with respective support formations (34, 36) on the foundations. One support formation defines a hinge component to restrain one of the feet for pivotal movement. The other support formation defines a platform on which the other foot can rest in any of various positions within a support area. This compensates for differences in level, spacing or alignment between the foundations. The lifting frame (12) can be transferred to another location by dismounting it from a first pair of foundations and then mounting it onto a second pair of like foundations in a corresponding manner.

(57) The invention relates to an anti-copy optical element comprising a caustic layer and a mask layer configured to simultaneously display a visible image reproducing a reference image and form a projected image containing a visible caustic pattern reproducing a reference pattern, upon illumination of the optical element with a light source, the projected image being distinct from the reference image. The invention also relates to a method for designing a relief pattern of a lightredirecting surface of said caustic layer consistently with the transmission properties of the mask layer.
